STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT — NOT APPLICABLE INCORPORATION-BY-REFERENCE OF MATERIAL SUBMITTED ON A COMPACT DISC — NOT APPLICABLE BACKGROUND OF THE INVENTION Technical Field of the InventionThis invention relates generally to computer networks and more particularly to an exchange item marketplace network.
Description of Related ArtThe use of credit cards, debit cards, and gift cards to pay for goods and services is well known. It is further known to use services such as PayPal™ or Apple Pay™ to expand the use of credit cards and debit cards through computing devices (e.g., computers, tablets, cell phones, etc.). The use of these services is aided by the standardized numbering system and format used by credit card issuers and debit card issuers.
For a credit card and debit card transaction, the credit or debit cardholder presents the credit or debit card to a merchant (e.g., on line or brick & mortar) to pay for a purchase. The merchant uses point of sale (POS) equipment to capture the information of the credit or debit card and to enter the amount of the purchase. This information is sent to an acquirer (e.g., the financial institution of the merchant). The acquirer sends the transaction information via a secure network of a credit card company to the cardholder's issuer (e.g., a financial institution that issued the credit or debit card to the cardholder).
The issuer approves or declines the transaction and sends the response back to the acquirer via the secure network of the credit card company. The acquirer sends the response (e.g., approved or declined) to the merchant to complete the transaction. Money, however, is not exchanged at the time of purchase, but is done during clearing and settlement.
Clearing and settlement begins when the merchant deposits the transaction receipt with the acquirer. The acquirer credits the merchant's account and sends the transaction receipt to the issuer via the secure network. The issuer posts the transaction to the cardholder's account. The cardholder pays the issuer in response to receiving a monthly statement.
The issuance and use of a gift card is significantly different than that of a credit card.
The processor service provides the gift cards to a distributor who is responsible for distributing the gift cards so that a consumer may purchase them. For example, the distributor may provide gift cards to merchants so they may sell the gift cards. At some point, a consumer purchases a gift card (e.g., a sporting goods company gift card for $50.00). The payment for the gift card is processed such that the distributor, processing service, and branded company each are paid their respective shares.
If the gift card is used, a merchant (e.g., a franchise owner of the branded company) captures information of the gift card via point of sale (POS) equipment. The information of the gift card is processed to determine if it is a valid gift card and to determine the balance remaining on the gift card. If the card is valid, the use of the gift card is authorized up to the balance remaining on the gift card. Once the use is complete, the balance is updated, processing fees are paid, and the branded company is debited.
Another difference between credit cards and gift cards is that gift cards do not have a standardized numbering system or format. As such, gift cards can have one of thousands of different numbering systems and formats, which have to be recognizable by the POS equipment.
Yet another different between credit cards and gift cards is when money is processed. For credit cards, money is not processed until a purchase occurs, while gift cards are purchased and then subsequently used. As such, money is processed at the time of purchase of the gift card and again if the gift card is used.
A still further difference between credit cards and purchased gift cards is that, if a credit card goes unused, no money is spent. In contrast, if a purchased gift card goes unused, money has been spent to acquire the card, but no goods or services are acquired. It is estimated that billions of dollars worth of purchased gift cards go unused annually. While this may be a favorable scenario for the branded company, it is not a favorable scenario for consumers.
As is further known, payment through digital means presents many trust and corruption issues for users and merchants.
Each of the user devices 12, 14, and 16 is a computing device that includes a computing core. In general, a computing device is any electronic device that can communicate data, process data, and/or store data. A further generality of a computing device is that it includes a central processing unit (CPU), a memory system, user input/output interfaces, peripheral device interfaces, and an interconnecting bus structure.
As specific examples, each of the user devices 12-16 may be a portable computing device and/or a fixed computing device. A portable computing device may be a social networking device, a gaming device, a cell phone, a smart phone, a personal digital assistant, a digital music player, a digital video player, a laptop computer, a handheld computer, a tablet, a video game controller, and/or any other portable device that includes a computing core. A fixed computing device may be a personal computer (PC), a computer server, a cable set-top box, a satellite receiver, a television set, a printer, a fax machine, home entertainment equipment, a video game console, and/or any type of home or office computing equipment that includes a computing core. An embodiment of a computing device 12-16 is further described below with reference to
The exchange item marketplace network 10 supports the selling and purchasing of exchange items. An exchange item is a closed loop financial instrument and/or other digital goods. For example, a closed loop financial instrument is a gift card, a voucher, a store credit, and/or other brand company (or merchant) sponsored form of credit for a specific use (e.g., in a specific store, in a specific chain of stores, for a particular type of goods, etc.). A closed loop financial instrument is distinguished from an open loop financial instrument, such as a credit card.
A digital good is digital item that can legally be sold or resold by an individual. For example, the digital item may be an original digital book, an original digital photograph, an original video clip, a purchased video game, a purchased software application, a purchase video, a purchased music file, a purchased digital book, a purchased audio book, etc. In support of selling an exchange item, the marketplace server 18 communicates with a user device of a seller (e.g., individual or bulk) to verify the user device (and the seller) and to ascertain information regarding the exchange item being offered for sale. For example, the marketplace server 18 verifies user information (e.g., the seller's name, account, personal identification number (PIN), a user identification number (ID), payment account information (e.g., a credit card number, checking or savings account information), seller's mailing address, etc.) and device information (e.g., an IP address, device serial number, a marketplace application ID, etc.) of the seller's computing device. Verification of the seller and corresponding computing device is discussed in greater detail with reference to
Upon receiving the information regarding the exchange item, which includes a brand name (e.g., a coffee franchise, a sporting good franchise, an electronics store, etc.), a serial number, a selling price, a remaining balance, restrictions of use, a bar code, and/or other pertinent information, the marketplace server 18 verifies it. When the seller and the information regarding the exchange item are verified, the marketplace server 18 posts it in the virtual marketplace of exchange items 22, which is stored in database 20.
The marketplace server 18 posts the exchange item in the virtual marketplace 22 by creating a digital representation of the exchange item. To do this, the server creates a digital image of the exchange item, determines the brand of the exchange item, and the information regarding the exchange item (e.g., a brief description, brand, selling price, balance, serial number, restrictions (if any), expiration date (if any), and/or any other pertinent information). In accordance with an organization protocol of the virtual marketplace, the digital representation of the exchange item is added. For instance, the organization protocol groups exchange items by types (e.g., restaurants, sporting goods, coffee shops, automotive goods, etc.), by brands (e.g., a sporting goods chain, a coffee shop chain, etc.), by sales price, by balance of the exchange item, by a savings value (e.g., a difference between the balance and the sales price), by expiration date, by date offered for sale, by special promotions, by seller, by restrictions, by a brief description (e.g., title of a video for resale), and/or any other organization scheme that lends itself to searching for particular items.
As such, for a particular exchange item offered for sale, its digital representation is added to the database 20 and will be displayed within a grouping per the organization protocol when a potential buyer or other user of the system 10 selects the grouping. In one example, if the exchange item is a gift card, a digital image of the gift card is displayed along with at least some of the related information (e.g., sales price, balance, etc.). If the gift card includes a logo of the branded company offering the gift card, the logo is often displayed in accordance with requirements of the branded company.
A potential buyer of an exchange item offered for sale accesses the system 10 using its user device 16. For example, the user device 16 logs into the system 10. If the user device 16 is associated with a buyer that does not have an account with the system 10, the buyer creates one through the user device 16 with the system. For buyers with an account, the marketplace server 18 verifies the buyer user device 16 before allowing it access to the virtual marketplace 22. The buyer verification process is discussed in greater detail with reference to
The buyer computing device 16 receives an input corresponding to a selection of one of the exchange items of interest for purchase. The buyer computing device 16 sends the selected exchange item to the marketplace server 18 for processing.
The marketplace server 18 processes the selected exchange item via a multiple step process. One step includes verifying that the buyer is authorized to purchase the exchange item (e.g., has the financial resources, is not limited by buying restrictions (e.g., dollar amount, quantity, type, etc.), is a legitimate buyer, etc.). Another step includes verifying integrity of the information of the selected exchange item (e.g., balance remaining is accurate, the offer to sell the exchange item has not been withdrawn, the exchange item is not currently being processed for sale to another buyer, the exchange item is not expired, the exchange item has not been voided by the branded company, etc.).
When the buyer is authorized and the information regarding the selected exchange item has been verified, another step includes removing the exchange item from the virtual marketplace 22. Another step includes processing payment for the selected exchange item. The multiple step buying process is further described with reference to
The computing core 52 includes a video graphics processing unit 60, one or more processing modules 62, a memory controller 64, main memory 66 (e.g., RAM), one or more input/output (I/O) device interface module 68, an input/output (I/O) interface 70, an input/output (I/O) controller 72, a peripheral interface 74, one or more USB interface modules 76, one or more network interface modules 78, one or more memory interface modules 80, and/or one or more peripheral device interface modules 82. Each of the interface modules 68, 76, 78, 80, and 82 includes a combination of hardware (e.g., connectors, wiring, etc.) and operational instructions stored on memory (e.g., driver software) that is executed by the processing module 62 and/or a processing circuit within the interface module. Each of the interface modules couples to one or more components of the computing device 12-16. For example, one of the IO device interface modules 68 couples to an audio output device 56. As another example, one of the memory interface modules 80 couples to flash memory 92 and another one of the memory interface modules 80 couples to cloud memory 98 (e.g., an on-line storage system and/or on-line backup system).
The computing core 122 includes a video graphics processing unit 60, a plurality of processing modules 62, a memory controller 64, a plurality of main memories 66 (e.g., RAM), one or more input/output (I/O) device interface module 68, an input/output (I/O) interface 70, an input/output (I/O) controller 72, a peripheral interface 74, one or more network interface modules 78, and/or one or more memory interface module 80.
The MP server 18 performs function blocks that includes a seller verification 200, a deny 202, an exchange item verification 204, an add exchange item to marketplace 206, a buyer verification 208, a deny 210, an exchange item purchase verification 212, an exchange item payment processing 214, a remove exchange item from marketplace 216, an add exchange item to buyer's wallet 218, an exchange item use 220, and an exchange item balance update 222.
As an example of operation, the mobile application 198 of the seller's computing device 12 sends a request to sell an exchange item to the marketplace (MP) server(s) 18. The server 18 performs the seller verification 200 functional block to determine whether the seller and/or the seller's computing device 12 are a valid seller (e.g., device and/or seller are valid). When invalid, the server(s) 18 performs the deny 202 functional block to communicate a denial of the request to sell the exchange item to the seller's computing device 12.
When the seller is verified, the server performs the exchange item verification 204 functional block to determine whether the exchange item is valid (e.g., is a valid exchange item, perform a balance check with an associated entity, i.e., a retailer, etc.). When invalid, the server(s) perform the deny 202 functional block. When the exchange item is valid, the server(s) 18 perform the add exchange item to marketplace 206 functional block to add a digital representation of the exchange item to the virtual marketplace of exchange items 22 (e.g., creates a new entry for inventory within the virtual marketplace of exchange items 22). When a buyer desires to purchase an exchange item, the mobile application 198 of the buyer's computing device 16 sends a request to buy a selected exchange item to the MP server(s) 18. The server(s) 18 perform the buyer verification 208 functional block to determine whether the buyer is valid (e.g., the user and/or buyer computing device are valid). When invalid, the server(s) 18 perform the deny 210 functional block to issue a denial of the purchase request to the buyer's computing device 16.
When the buyer is validated, the server(s) 18 perform the exchange item purchase verification 212 functional block to verify that the buyer, via the buyer's computing device, has sufficient means (e.g., money, credit, valid credit card, valid debit card, etc.) to pay for the selected exchange item. For example, the exchange item purchase verification 212 functional block enables the server 18 to receive buyer information from the buyer's financial server 194 verifying payment and/or verifying an ability to pay. When unable to purchase the selected exchange item, the server 18 performs the deny 210 functional block.
When the buyer is able to purchase the selected exchange item, the server 18 performs the exchange item payment processing 214 functional block to process payment for the selected exchange item. For example, the server 18 collects payment from the buyer's e-wallet, the buyer's computing device 16, or the buyer's financial server 194, issues a payment to the seller's e-wallet, to the seller's computing device, or to the seller's financial server 190, and issues a commission payment to the service provider's financial server 192.
After processing payment or concurrent with the processing of the payment, the server 18 performs the remove exchange item from marketplace 216 functional block to remove the selected exchange item from the virtual marketplace of exchange items 22. For example, the server 18 deletes an entry associated with the selected exchange item from the database 20.
The server 18 performs the add exchange item to the buyer's wallet 218 functional block to facilitate adding the exchange item to a buyer's e-wallet. For example, the server 18 updates a representation of the buyer's wallet within the database 20 to include a digital representation of the purchased exchange item and issues a message to the mobile application 198 to store a local copy of the digital representation within the buyer's computing device 16.
When the buyer desires to purchase something using an exchange item, the mobile application 198 communicates a utilization message to the server 18. The server 18 evokes the exchange item use 220 functional block to receive the utilization message and to facilitate communication with other servers for verification and transaction execution. For example, the server 18 forwards the utilization message to a retailer server associated with the exchange item to initiate execution of the transaction. Having successfully used the exchange item, the server 18, via the exchange item balance update 222 functional block, updates the buyer's wallet to indicate that the exchange item has been utilized and to update the balance remaining on the exchange item, when appropriate.
Each seller 702 and each buyer 704 corresponds to a computing device 12-16 that includes a marketplace interface module 716 that enables the computing device access to the marketplace 700 and to function therein. The marketplace interface module 716 includes a browser application 722, a mobile device application 720, and/or any type of application that enables access to the marketplace 700. The computing core 52 of the user device executes one or more of these applications. For instance, each of the applications includes operational instructions that are stored in memory (e.g., main memory, flash memory, SS memory, HD memory, and/or cloud memory) and executed by the processing module 62 of the computing core 52.
Alternatively, the marketplace interface module 716 includes a processing circuit and memory, wherein the memory stores and the processing circuit executes the operational instructions of the application. As yet another alternative, the processing circuit of the marketplace interface module 716 and the processing module 62 of the computing core 52 co-process the operational instructions of one or more of the applications. Interface 718 functions in a similar manner to provide bulk resellers 708 and/or retailers 710 access and function within the marketplace 700.
One or more marketplace servers 18 supports the on-line exchange item (EI) marketplace 700 by performing the functions of the corresponding functional blocks. The functional blocks include seller software tools 738, individual seller fraud detection 724, individual sale processing 726, bulk seller verification processing 730, bulk sale processing 732, retailer verification processing 734, retailer sale processing 736, displaying exchange items for sale 728 in the marketplace 700, payment processing 748, MP user e-wallet 750, buyer fraud detection 740, purchase processing 742, consumer profiles 744, and market customization 746. A functional block includes one or more of a standalone processing module that executes operational instructions to perform the corresponding functions of the block, a software algorithm executed by the computer core of the server to perform the corresponding functions of the block, and/or a combination thereof.
The server(s) 18 perform the marketplace user e-wallet functional block 750 to create and maintain an e-wallet for a user of the marketplace 700. The e-wallet is essentially a file for an individual user (e.g., a person, a legal entity, etc.) that stores information regarding exchange items bought, sold, and/or used by the user. For example, the e-wallet stores a digital representation of each purchased exchange item that has a value greater than zero. For example, a digital representation of a gift card is displayed in an asset section of the e-wallet while the gift card has a balance above zero and the gift card has not expired. When the balance is zero or the gift card expires, the digital representation is removed and the information regarding the gift card is stored in an archive section of the e-wallet.
The e-wallet is further capable of storing and tracking marketplace credit. For example, a user may purchase marketplace credit that is subsequently used to purchase an exchange item.
In addition, a seller of an exchange item may be paid in marketplace credit that the seller may use to purchase an exchange item or cash out.
The e-wallet further functions to archive data regarding previous exchange item purchases and/or previous exchange item sales. The amount of data stored for each exchange item purchase or sale may be user defined or set based on a system default setting. For example, the data for a purchase includes one or more of a purchase price, the exchange item ID, a serial number, a brand name, a purchase date, the value of the exchange item, restrictions of the exchange item, and an expiration date. The data for a purchased exchange item may further include use information (e.g., when the exchanged item was used, the amount of value used, the date of use, the place of use, etc.) and/or remaining value information.
As another example, the data for a sale includes one or more of an asking selling price, a sold price, the exchange item ID, a serial number, a brand name, an offer for sale time stamp, a sold time stamp, the value of the exchange item, restrictions of the exchange item, and an expiration date. The data for a sold exchange item may further include price reduction information (e.g., the amount of the change, a change time stamp, etc.) and/or information regarding a withdrawal of an offer for sale.
The server(s) 18 perform the seller software tools functional block 738 to assist a seller (e.g., individual, bulk, or retailer) in setting a price for an exchange item. For example, the server(s) 18 record data regarding exchange items offered for sale, data regarding purchases of exchange items, and data regarding exchange items for which the offer for sale was withdrawn. From this data, the server(s) 18 determines predictive sales information. For example, the server(s) 18 determines for a particular type of exchange item (e.g., a gift card for a particular franchise) a correlation between the value of the exchange item and duration in the marketplace (e.g., a $250 gift card has an average duration of 1 day, a $100 gift card has an average duration of 12 hours, a $50 gift card has an average duration of 5 hours, etc.). As another example of predictive sales information, the server(s) 18 determine a correlation between sales price and duration in the marketplace (e.g., a 5% discount has an average duration of 12.5 hours, a 3% discount has an average of 1 day, and a 10% discount has an average duration of 1.5 hours). As yet another example, the server(s) 18 determine a periodic sales volume for a particular exchange item (e.g., how many sold in an hour, six hours, a day, etc.). As yet another example, the server(s) 18 determine a current quantity of the particular exchange items for sale (e.g., how many are currently being offered for sale, at what sales price, the current average duration in the marketplace, etc.). The server(s) 18 may further analyze any type of data maintained by the system 10A to assist in the creation of predictive sales information.
In addition to creating the predictive sales information, the server(s) 18 generate a seller's profile, which includes information regarding the sales tendencies and/or preferences of a particular seller. For example, the seller's profile includes information regarding one or more of the types of exchange items offered for sale, information regarding if and when exchange item offers for sale are withdrawn, initial asking prices for exchange items offered for sale, actual sales price information and corresponding discounted percentage, frequency for which initial asking price is adjusted, average duration of exchange items in the marketplace, standard deviation of duration of exchange items in the marketplace, etc.
From the predictive sales information and the seller's profile, the server(s) 18 provide a suggested sales price for a particular exchange item. For example, the seller profile indicates that the seller has a tendency to offer a particular exchange item with a minimal discount and prefers that the exchange item remain in the marketplace for less than 6 hours. Further, the predictive sales information for the particular exchange item indicates that there is currently above normal quantity of the exchange item for sale, the current asking price has a greater discount than the seller's preference, and the current average duration in the marketplace is 7 hours, the server(s) 18 provides one or more recommendations and corresponding predictive outcomes (e.g., an initial asking price below the seller's profile to sell the exchange item within 6 hours, an initial asking price corresponding to the seller's profile to sell the exchange item within 11 hours, etc.). The server(s) 18 may further provide the predictive sales information to the seller's computing device.
The server(s) 18 perform the individual seller fraud detection functional block 724 to automate detection of a fraudulent seller and/or a fraudulent exchange item. This includes the seller verification and the exchange item verification as discussed in
To extend the use of the marketplace to retailers or branded companies (i.e., the entity that initiates a gift card and ultimately accepts the gift card as payment), the server(s) 18 perform the retailer verification processing functional block 734 and the retailer sale processing functional block 736. The retailer verification processing functional block 734 includes one or more of setting up an account for a retailer to sell exchange items via the marketplace, verifying the retailer at least at the setup of the account and potentially for each transaction conducted via the marketplace, verifying the exchange items being offered for sale, and/or other verification mechanisms. As an example, a secure portal is established between the retailer seller and the marketplace server(s) 18 such that any communications via the secure portal is at least initially deemed a valid communication.
The retailer sale processing functional block 736 includes one or more of creating digital representations of the exchange items offered for sale, determining selling parameters and posting the digital representations and the parameters in the marketplace. The selling parameters include one or more of sales price, listing duration before changing price, restrictions, withdraw procedures, etc.
The server(s) 18 perform the buyer fraud detection functional block 740 to automate detection of a fraudulent buyer and/or fraudulent financial information used for purchasing. This includes the buyer verification and the purchase verification as discussed in
The server(s) 18 perform the consumer profiles functional block 744 for a buyer. For the buyer, its consumer profile includes data regarding exchange item purchases of the buyer. The data includes one or more of the exchange items purchased, frequency of purchases, average purchase price, average value of purchased like exchange items (e.g., coffee shop gift cards), preferred discounts, etc. Note that this may be included in the buyer's e-wallet or maintained as a separate file.
The server(s) 18 perform the market customization functional block 746 to customize marketing of exchange items being offered for sale to particular buyers based on their buyer profiles. The market customization functional block 746 further includes determining a type and a quantity of exchange items a retailer should offer for sale and directing marketing efforts to a particular segment of buyers. In this manner, the system 10A efficiently and effectively couples exchange items for sale to buyers who typically buy such exchange items.
The server(s) 18 perform the individual sales processing function block 726, the bulk seller verification processing functional block 730, the bulk sale processing functional block 732, and the purchase processing functional block 742 as described with reference to one or more of
The marketplace database 20 includes a variety of databases, such as an agreement database 930, a user database 932, and an exchange item database 934. Each of the databases will be discussed in greater detail with reference to following figures. The marketplace server 18 includes a variety of processing capability, which may be implemented as a plurality of processing modules. In an embodiment, the marketplace server 18 includes a set of processing 936, a sale processing 938, a use processing 940, and a rule processing 942. Each of the processing modules will be discussed in greater detail with reference to following figures.
The EI buyer computing device 926 includes a digital wallet 944 and the initial owner computing device 928 includes another digital wallet 946. Each of the digital wallets 944-946 is utilized to store a variety of information associated with one or more exchange items, such as balance information, pricing information, history of sale, brand affiliation, rules, conditions, use options, owner information, and security information to ensure trust of the content of the digital wallet.
In an example of operation of the generating of the transactions blockchain, the EI distributor 800 generates a block 0 of the transactions blockchain to establish exchange item (EI) information when determining to offer an exchange item for sale. The determining may be based on one or more of receiving a purchase request from the seller's computing device 12, receiving a bulk EI creation request, receiving the EI information from one or more of a branded company server and a processor service, and interpreting a schedule. For example, the EI distributor 800 determines to establish the EI information when receiving, via the processor service, EI information for a plurality of exchange items from the branded company server. As another example, the EI distributor 800 determines to establish the EI information when receiving, via a retail point-of-sale device, a purchase request for the EI from the seller's computing device 12.
Having determined to offer the EI for sale, the EI distributor 800 obtains the EI information. The obtaining includes receiving the EI information from the processor service and generating the EI information. The generating the EI information includes obtaining one or more of available balance, serial number, personal identification number (PIN), brand, EI type, expiration date, pricing approach, purchase restrictions, a hash of one or more of the elements of the EI information (e.g., a secure hash of the EI type using a private key of a private/public key pair of the brand server(s) 26), and the public key of the private/public key pair of the brand server(s) 26. Having obtained the EI information, the EI distributor 800 generates the block 0 to include the EI information.
The generating of the block 0 includes populating the block zero with a representation of the EI information and establishing trust for the block 0 utilizing a trust approach. The trust approach includes at least one of a digital signature approach utilizing a private key of a private/public key pair of the EI distributor 800 and encrypting the EI information utilizing the private key of the private/public key pair of the EI distributor 800 to produce the representation of the EI information. For example, the EI distributor 800 encrypts the EI information and the public key of the EI distributor 800 utilizing the private key of the EI distributor 800 to produce the transaction section of the block 0 when utilizing the encryption trust approach. As another example, the EI distributor 800 utilizes the private key of the EI distributor 800 to generate a digital signature over the EI information and the public key of the EI distributor 800 to produce the transaction section of the block 0.
When receiving the EI purchase request from the seller's computing device 12, the EI distributor 800 generates a block 1 of the EI transactions chain to indicate that the seller's computing device 12 is purchasing the EI from the EI distributor 800, where the block 1 is chained to the block 0 in accordance with a trusted chaining approach, and where the block 1 is generated utilizing the trust approach (e.g., as utilized when generating the block 0). The trusted chaining approach is discussed in greater detail with reference to
The generating of the block 1 includes generating seller to distributor payment information 1 (e.g., purchase price of this transaction, a timestamp of this transaction, purchaser identifier, and the transaction portion of the previous block), and establishing trust for the block 1 utilizing the trust approach. For example, the EI distributor 800 obtains a public key of a private/public key pair of the seller's computing device 12, encrypts the seller to distributor payment information 1 and the public key of the seller's computing device 12 utilizing the private key of the EI distributor 800 to produce the transaction portion of the block 1 when utilizing the encryption trust approach. As another example, the EI distributor 800 utilizes the private key of the EI distributor 800 to generate a digital signature over the seller to distributor payment information 1 and the public key of the seller's computing device 12 to produce the transaction section of the block 1.
Having generated the block 1 chained to the block 0, the EI distributor 800 issues secure EI information 804 to the seller's computing device 12. The issuing includes generating the secure EI information 804 to include the EI transactions chain (e.g., blocks 0-1) and sending the secure EI information 804 to the seller's computing device 12.
When determining to offer the EI for sale via the virtual marketplace of exchange items 22, the seller's computing device 12 issues secure EI information 806 to the MP servers 18, where the secure EI information 806 includes one or more of the secure EI information 804 and a request to sell the EI via the virtual marketplace of exchange items 22. Having received the secure EI information 806, MP servers 18 communicates pricing information 808 with the seller's computing device 12, where the pricing information 808 includes one or more of a desired price, a desired price range, a recommended price range, a recommended price, and a confirmed price.
Having communicated the confirmed price, the seller's computing device 12 and the MP servers 18 communicates secure sale information 810. For example, the MP servers 18 updates inventory information 809 (e.g., brand, balance, price, expiration date, volume, pricing rules by brand, etc.) to provide a representation of the EI for storage in the database 20 based on the transaction portion of the block 1, the MP servers 18 provides a public key of a private/public key pair of the MP servers 18 to the seller's computing device 12, and the seller's computing device 12 generates a block 2 of the EI transactions chain to indicate that the MP servers 18 is representing the EI for purchase by a buyer's computing device 16, where the block 2 is chained to the block 1 in accordance with the trusted chaining approach, and where the block 2 is generated utilizing the trust approach (e.g., as utilized when generating the block 1).
The generating of the block 2 includes generating a marketplace to seller representation and/or payment information 2 (e.g., desired price, a timestamp of this transaction, purchaser identifier, and the transaction portion of the previous block), and establishing trust for the block 2 utilizing the trust approach. For example, the seller's computing device 12 obtains the public key of a private/public key pair of the MP servers 18, encrypts the seller representation and/or payment information 2 and the public key of the MP servers 18 utilizing the private key of the seller's computing device 12 to produce the transaction section of the block 2 when utilizing the encryption trust approach. As another example, the seller's computing device 12 utilizes the private key of the seller's computer device 12 to generate a digital signature over the seller representation and/or payment information 2 and the public key of the MP servers 18 to produce the transaction portion of the block 2.
Having generated the block 2 chained to the block 1, the seller's computing device 12 issues the secure sale information 810 to the MP servers 18. The issuing includes generating the secure sale information 810 to include the EI transactions chain (e.g., blocks 0-2) and sending the secure sale information 810 to the MP servers 18.
When determining to purchase the EI for sale via the virtual marketplace of exchange items 22, the buyer's computing device 16 issues an EI purchase request 812 to the MP servers 18, where the EI purchase request 812 includes a request to purchase the EI (e.g., buyer's computing device 16 identifier, public key of a private/public key pair of the buyer's computing device 16, a purchase price, etc.). Having received the EI purchase request 812, the MP servers 18 communicate secure buyer wallet information 814 with the buyer's computing device 16. For example, the buyer's computing device 16 sends payment instructions to the MP servers 18 (e.g., purchase price, payment account information), the MP servers 18 generates a block 3 of the EI transactions chain to indicate that the buyer's computing device 16 is purchasing the EI for the purchase price amount, where the block 3 is chained to the block 2 in accordance with the trusted chaining approach, and where the block 3 is generated utilizing the trust approach (e.g., as utilized when generating the block 2).
The generating of the block 3 includes generating buyer to marketplace payment information 3 (e.g., a confirmed purchase price, payment instructions, a timestamp of this transaction, purchaser identifier, and the transaction portion of the previous block), and establishing trust for the block 3 utilizing the trust approach. For example, the MP servers 18 obtains the public key of the private/public key pair of the buyer's computing device 16, encrypts the buyer to marketplace payment information 3 and the public key of the buyer's computing device 16 utilizing the private key of the MP servers 18 to produce the transaction section of the block 3 when utilizing the encryption trust approach. As another example, the MP servers 18 utilizes the private key of the MP servers 18 to generate a digital signature over the buyer to marketplace payment information 3 and the public key of the buyer's computing device 16 to produce the transaction section of the block 3.
Having generated the block 3 chained to the block 2, the MP servers 18 issues secure buyer wallet information 814 to the buyers computing device 16. The issuing includes generating the secure buyer wallet information 814 to include the EI transactions chain (e.g., blocks 0-3) and sending the secure buyer wallet information 814 to buyer's computing device 16, where the mobile app 198 facilitates storage of the transactions chain as a secure EI record 822 in the flash memory 92.
When the buyer's computing device 16 determines to utilize the EI for payment of a transaction with the retailer computing device 802, the buyer's computing device 16 sends a transaction request 816 to the retailer computing device 802, where the transaction request 816 includes one or more of a retail transaction identifier of the transaction with the retailer computing device 802, and payment instructions that identifies the EI.
Having received the transaction request 816, the retailer computing device 802 and the buyer's computing device 16 communicate secure balance verification 818. The communicating of the secure balance verification information 818 includes the buyer's computing device 16 sending one or more of the secure EI record 822 (e.g., blocks 0-3) to the retailer computing device 802 and the public key of the private/public key pair of the MP servers 18.
Having received the secure EI record 822, the retailer computing device 802 verifies that a sufficient balance level is associated with the secure EI record 822 to facilitate completion of the transaction request 816. For example, the retailer computing device 802 decrypts the secure transaction section of the secure EI record 822 utilizing the public key of the MP servers 18 to reveal the balance level and a public key of the buyer's computing device 16 for verification with a public key received directly from the buyer's computing device 16. The retailer computing device 802 indicates favorable verification when the revealed balance level is sufficient and the received public key from the buyer's computing device 16 compares favorably (e.g., substantially the same) to the revealed public key from the secure EI record 822. As another example, the retailer computing device 802 verifies a signature over the secure transaction portion of the secure EI record 822 utilizing the public key of the MP servers 18 to verify the balance level and to verify the public key of the buyer's computing device 16. The retailer computing device 802 indicates favorable verification when the verified balance level is sufficient and the public key from the buyer's computing device 16 is verified from the secure EI record 822. As yet another verification example, the retail computing device 802 decrypts the hash of the one or more of the elements of the EI information using the private key of the EI distributor 800 (e.g., or a brand server(s) 26) and indicates favorable verification when the decrypted hash is substantially the same as a calculated hash over the one or more of the elements of the EI information. As such, the EI can be considered a legitimately issued EI from the brand server(s) 26 (e.g., from the brand owner).
When the verifications are favorable, the retailer computing device 802 and the buyer's computing device 16 communicate secure transaction completion 820. For example, the buyer's computing device 16 sends payment instructions to the retailer computing device 802 (e.g., purchase price, EI information), the buyer's computing device 16 generates a block 4 of the EI transactions chain to indicate that the buyer's computing device 16 is utilizing the EI for the purchase price amount, where the block 4 is chained to the block 3 in accordance with the trusted chaining approach, and where the block 4 is generated utilizing the trust approach (e.g., as utilized when generating the block 3).
The generating of the block 4 includes generating buyer to retailer payment information 4 (e.g., a confirmed purchase price, payment instructions utilizing the EI, a timestamp of this transaction, purchaser identifier, and the transaction portion of the previous block), and establishing trust for the block 4 utilizing the trust approach. For example, the buyer's computing device 16 obtains the public key of the private/public key pair of the retailer computing device 802, encrypts the buyer to retailer payment information 4 and the public key of the retailer computing device 802 utilizing the private key of the buyer's computing device 16 to produce the transaction section of the block 4 when utilizing the encryption trust approach. As another example, the buyer's computing device 16 utilizes the private key of the buyer's computing device 16 to generate a digital signature over the buyer to retailer payment information 4 and the public key of the retailer computing device 802 to produce the transaction section of the block 4.
Having generated the block 4 chained to the block 3, the buyer's computing device 16 issues the secure transaction completion 820 to the retailer computing device 802. The issuing includes generating the secure transaction completion 820 to include the EI transactions chain (e.g., blocks 0-4) and sending the secure transaction completion 820 to the retailer computing device 802, where the mobile app 198 may facilitate storage of an updated transactions chain as an updated secure EI record 822 in the flash memory 92. Alternatively, or in addition to, each of the seller's computing device 12, the MP servers 18, and the buyer's computing device 16 may validate information within the EI transactions chain by validating the chaining of each block to a next block utilizing the trusted chaining approach and may further validate information with the EI transactions chain by validating integrity of the transaction section of one or more of the blocks utilizing the trust approach (e.g., verifying a signature, decrypting an encrypted transaction to reveal a public key for verification).
In another example of operation of the generating of the transactions blockchain, at least one of the EI distributor 800, the seller's computing device 12, and the MP server(s) 18, authenticates value of an exchange item to produce an authenticated value of the exchange item. The exchange item includes one of a closed loop financial instrument and a digital good. The authenticating of the value includes a variety of authenticating approaches.
A first authenticating approach includes the seller's computing device 12 authenticating the value of the exchange item via a communication with a brand server (e.g., issue an authentication request, interpret a received verification response to identify an available balance of the exchange item associated with the brand server), generating a secure exchange item package, and securely passing, by the seller's computing device 12 to the marketplace servers 18, control over the secure exchange item package such that the marketplace server 18 obtains the control over the secure exchange item package. The securely passing includes updating a transaction section of the secure exchange item package by including a public key of a recipient device (e.g., the marketplace servers 18) of the secure exchange item package and signing the secure exchange item package by a transferring device (e.g., the seller's computing device 12) of the secure exchange item package. The secure exchange item package includes a header section and a transaction section. The secure exchange item package is discussed in greater detail with reference to
With the authenticated value of the exchange item produced, the marketplace servers 18 obtains control over the secure exchange item package, where the secure exchange item package includes identity of the exchange item, identity of an authenticated owner of the exchange item, identity of the marketplace server, and the authenticated value (e.g., face value of the exchange item or remaining balance of the exchange item) of the exchange item and where only a device possessing control over the secure exchange item package may modify the secure exchange item package.
As an example of the obtaining of the control, the marketplace servers 18 receives from the seller's computing device 12, a request to sell the exchange item (e.g., receives the secure EI information 806). In response to valid processing of the request to sell (e.g., communicating pricing information 808), the seller's computing device 12 securely passes, to the marketplace servers 18, control over the secure exchange item package (e.g., communicates secure sale information 810). Having obtained control, the marketplace servers 18 lists a representation of the exchange item for sale by storing associated inventory information 809 in the database 20 to update the virtual marketplace of exchange items 22.
With the exchange item represented within the virtual marketplace of exchange items 22, the marketplace server 18 receives, from the buyer's computing device 16, a request to purchase the exchange item (e.g., the EI purchase request 812). Having received the request to purchase the exchange item, the marketplace servers 18, in response to valid processing of the request to purchase the exchange item (e.g., exchanging secure buyer wallet information 814), securely passes to the buyer computing device 16, control over the secure exchange item package (e.g., via the secure buyer wallet information 814). Having received the secure buyer wallet information 814, the mobile app 198 stores the secure buyer wallet information 814 as the secure EI record 822 in the flash memory 92.
For use of the exchange item (e.g., as initiated with the transaction request 816), the buyer computing device 16 securely passes, to the retailer computing device 802 (e.g., the merchant server), control over the secure exchange item package. The use may further include the retailer computing device 802 into verifying that the balance of the exchange item is sufficient for a purchase transaction by communicating secure balance verification 818 with the buyer's computing device 16.
With control over the secure exchange item package, the merchant server (e.g., the retailer computing device 802) executes use of the exchange item by updating the value of the exchange item to produce an updated value of the exchange item. For example, the retailer computing device 802 subtracts an amount of the purchase transaction (e.g., for goods provided by a retailer to a user of the buyer's computing device 16) from the value of the exchange item to produce the updated value of the exchange item.
Having generated the updated value of the exchange item, the retailer computing device 802 generates an updated secure exchange item package, where the updated secure exchange item package includes identity of the exchange item, identity of the merchant server, identity of the buyer computing device, and the updated value of the exchange item. Having generated the updated secure exchange item package, the merchant server (e.g., the retailer computing device 802) securely passes control over the updated secure exchange item package to the buyer's computing device 16 (e.g., by communicating the secure transaction completion 820).
Alternatively, or in addition to, for a second use of the exchange item, the buyer's computing device 16 securely passes, to a second merchant server, control over the updated secure exchange item package. The second merchant server executes the second use of the exchange item by updating the updated value of the exchange item to produce a second updated value of the exchange item, generating a second updated secure exchange item package, where the second updated secure exchange item package includes identity of the exchange item, identity of the second merchant server, identity of the buyer's computing device 16, and the second updated value of the exchange item, and securely passes, to the buyer's computing device 16, control over the second updated secure exchange item package.
An example of operation of the generating of the secure exchange item package, when the user device 2 has control of the secure exchange item package and is passing control of the secure exchange item package to the user device 3 (e.g., the user device 3 is transacting an exchange with the user device 2), the user device 2 obtains the user 3 public key from the user device 3, performs a hash function 2 over the user 3 public key and the transaction 2 to produce a hashing resultant (e.g., preceding transaction to user device 2) and performs a signature function 2 over the hashing resultant utilizing a user 2 private key to produce a user 2 signature. Having produced the user 2 signature, the user device 2 generates the transaction 3 to include the user 3 public key, the user 2 signature, user 3 payment to the user 2 information, and EI information 2-3. The user 3 payment to the user 2 information includes payment instructions from user 3 to user 2. The EI information 2-3 includes an updated balance of the exchange item (e.g., after the transaction between the user device 3 and the user device 2), a serial number of the exchange item, an expiration date of the exchange item, a type of the exchange item, a brand identifier, an image, a personal identification number, and utilization rules for the exchange item.
Having produced the transaction 3 section of the block 3 (e.g., a secure exchange item package 3), a processing module (e.g., of the user device 2, of the user device 3, of a transaction mining server, of the marketplace server 18) generates the header section by performing a hashing function over the transaction section 3 to produce a transaction 3 hash, performing the hashing function over the preceding secure exchange item package (e.g., block 2) to produce a block 2 hash. The performing of the hashing function may include generating a nonce such that when performing the hashing function to include the nonce of the header section, a desired characteristic of the resulting hash is achieved (e.g., a desired number of preceding zeros is produced in the resulting hash).
Having produced the secure exchange item package 3, the user device 2 sends the secure exchange item package 3 to the user device 3. Having received the secure exchange item package 3, the user device 3 validates the received secure exchange item package 3. The validating includes one or more of verifying the user 2 signature over the preceding transaction section (e.g., transaction 2) and the actual user 3 public key utilizing the user 2 public key (e.g., a re-created signature function result compares favorably to user 2 signature) and verifying that an extracted user 3 public key of the transaction 3 compares favorably to the user 3 public key held by the user device 3. The user device 3 considers the received secure exchange item package 3 validated when the verifications are favorable (e.g., the available balance of the exchange item is trusted).
As an example of the authenticating the value of the exchange item, a seller device authenticates the value of the exchange item via a communication with a brand server, generates a secure exchange item package, and securely passes, to the marketplace server, control over the secure exchange item package such that the marketplace server obtains the control over the secure exchange item package. The securely passing includes updating a transaction section of the secure exchange item package by including a public key of a recipient device of the secure exchange item package and signing the secure exchange item package by a transferring device of the secure exchange item package. The secure exchange item package includes a header section and a transaction section. As another example of the authenticating the value of the exchange item, the marketplace server authenticates the value of the exchange item via a communication with the brand server, generates the secure exchange item package, and obtains control over the secure exchange item package as a result of being an originator of the secure exchange item package.
The method continues at step 832 where the marketplace server obtains control over the secure exchange item package, where the secure exchange item package includes identity of the exchange item, identity of an authenticated owner of the exchange item, identity of the marketplace server, and the authenticated value (e.g., face value of the exchange item and/or a remaining balance of the exchange item) of the exchange item and where only a device possessing control over the secure exchange item package may modify the secure exchange item package. As an example of the obtaining of the control, the marketplace server receives, from the seller device, a request to sell the exchange item and in response to valid processing of the request to sell, the seller device securely passes, to the marketplace server, control over the secure exchange item package.
The method continues at step 834 where the marketplace server receives, from a buyer device, a request to purchase the exchange item. In response to valid processing of the request to purchase the exchange item, the method continues at step 836 where the marketplace server securely passes, to the buyer device, control over the secure exchange item package. For use of the exchange item, the method continues at step 838 where the buyer device securely passes, to a merchant server, control over the secure exchange item package.
The method continues at step 840 where the margin server executes use of the exchange item by updating the value of the exchange item to produce an updated value of the exchange item (e.g., deducting a purchase price of a purchase transaction from the value of the exchange item to produce the updated value the exchange item). The method continues at step 842 where the merchant server generates an updated secure exchange item package, where the updated secure exchange item package includes identity of the exchange item, identity of the merchant server, identity of the buyer device, and the updated value of the exchange item. The method continues at step 844 where the merchant server securely passes, to the buyer device, control over the updated secure exchange item package.
Alternatively, or in addition to, for a second use of the exchange item, the buyer device securely passes, to a second merchant server, control over the updated secure exchange item package. The second merchant server executes the second use of the exchange item by updating the updated value of the exchange item to produce a second updated value of the exchange item, generates a second updated secure exchange item package, where the second updated secure exchange item package includes identity of the exchange item, identity of the second merchant server, identity of the buyer device, and the second updated value of the exchange item, and securely passing, to the buyer device, control over the second updated secure exchange item package.
The method described above in conjunction with one or more of the processing module, the seller device, the marketplace server, the buyer device, the merchant server, the second merchant server, can alternatively be performed by other modules of the exchange item marketplace network or by other devices. In addition, at least one memory section (e.g., a non-transitory computer readable storage medium, a computer readable memory) that stores operational instructions can, when executed by one or more processing modules of one or more computing devices of the exchange item marketplace network, cause the one or more computing devices to perform any or all of the method steps described above.
When receiving an EI purchase request from a seller computing device, the method continues at step 852 where a processing module of an EI distribution entity generates a first block of the EI transactions chain, where the EI distribution entity signs the transaction portion of the first block, where the transaction portion indicates that the seller computing device is purchasing the EI from the distribution entity, and where the first block is chained to the origination block in accordance with a chained security approach (e.g., hash of transaction portion, hash of a previous block). The EI distribution entity may be implemented utilizing the EI origination entity. For example, the EI distribution entity signs the transaction portion utilizing a private key of a private/public key pair of the seller computing device to produce the transaction portion of the first block.
When transacting a representation of the EI with a marketplace server, the method continues at step 854 where the seller computing device generates a second block of the EI transactions chain, where the seller computing device signs a transaction portion of the second block, where the transaction portion indicates that the MP server is representing the EI for the seller computing device, and where the second block is chained to the first block in accordance with the chained security approach. For example, the MP server receives secured EI information from the seller computing device (e.g., an offer for sale), provides pricing information to the seller computing device, receives a confirmed price from the seller computing device, issues secure sale information to the seller computing device, and updates inventory information within a virtual exchange item marketplace, where the secure sale information includes the second block of the EI transactions chain and a public key of the MP server.
When receiving a purchase request for the EI from a buyer computing device, the method continues at step 856 where the MP server generates a third block of the EI transactions chain, where the MP server signs a transaction portion of the third block, where the transaction portion indicates that the buyer computing device is purchasing the EI from the seller computing device via the marketplace, and where the third block is chained to the second block in accordance with the chained security approach. For example, the buyer computing device issues an EI purchase request to the MP server based on received inventory information from the MP server, the MP server generates secure buyer wallet information, the buyer computing device stores a security EI record, where the secure buyer wallet information includes the third block of the EI transactions chain and the secure EI record includes the EI transactions chain. For instance, the MP server signs a public key of the buyer computing device and the transaction portion utilizing a private key of a private/public key pair of the MP server to produce the transaction portion of the third block.
When utilizing the EI for payment in a purchasing transaction with a retailer computing device, the method continues at step 858 where the buyer computing device generates a fourth block of the EI transactions chain, where the buyer computing device signs a transaction portion of the fourth block, where the transaction portion indicates that the buyer computing device is utilizing the EI for payment in the purchasing transaction, and where the fourth block is chained to the third block in accordance with the chained security approach. For example, the buyer computing device issues a transaction request to the retailer computing device, the retailer computing device exchanges secure balance information with the buyer computing device (e.g., verifies the trust of the EI transactions chain, where the EI transactions chain indicates an available balance of the EI verifying that an available balance is sufficient), the retailer computing device issues secure transaction completion information to the buyer computing device, where the secure transaction completion information includes the fourth block of the EI transactions chain. The buyer computing device signs the public key of the retailer computing device and the transaction portion to produce a transaction portion of the fourth block. Alternatively, or in addition to, each entity of the plurality of transactions may verify the EI transactions chain by verifying a stored public key matches to recovered public keys when validating signatures over associated blocks.
The method described above in conjunction with the exchange item origination entity, the seller computing device, the buyer computing device, and the retailer computing device can alternatively be performed by other modules of the exchange item marketplace network or by other devices. In addition, at least one memory section (e.g., a non-transitory computer readable storage medium, a computer readable memory) that stores operational instructions can, when executed by one or more processing modules of one or more computing devices of the exchange item marketplace network, cause the one or more computing devices to perform any or all of the method steps described above.
The establishing of the conditions includes utilizing the predetermination, interpreting the lookup, interpreting a query response, receiving the conditions, identifying the conditions based on or more of identification of the initial owner, identification of the brand of the EI, an EI type indicator, and EI serial number, and an EI utilization rule, etc. For example, the marketplace server performs a lookup based on a serial number of the exchange item to establish the initial conditions.
The method continues at step 866 where the processing module determines whether the EI has been used (e.g., redeemed, utilized for making a purchase, bartered, etc.). The determining includes interpreting a status associated with the EI of an exchange item database, interpreting a received a use message, receiving purchase transaction information, etc. the method branches to step 874 when the processing module determines that the EI has not been used. The method continues to step 868 when the processing module determines that the EI has been used.
When the EI has been used, the method continues at step 868 where the processing module processes the EI use. The processing includes one or more of facilitating completion of a purchase transaction, facilitating payment distribution, and updating the exchange item database to indicate the use. The method continues at step 870 where the processing module determines whether the EI is exhausted (e.g., no value left). The determining includes comparing a balance value associated with the EI to a minimum threshold level (e.g., zero dollars). For example, the processing module indicates that the EI has been exhausted when the balance value is zero. The method looks back to step 866 when the EI is not exhausted. The method continues to step 872 when the EI is exhausted where the EI is retired. Alternatively, and in accordance with a rule associated with exchange item, the processing module maintains the zero balance exchange item without retiring the exchange item (e.g., to keep open an opportunity to refresh the exchange item). The retiring includes the processing module updating the exchange item database to indicate that the EI has been exhausted and retired from use.
When the EI has not been utilized, the method continues at step 874 with a processing module determines whether the EI is to be offered for sale. The determining includes receiving a request to offer the EI for sale, interpreting a rule with regards to sale, interpreting a status associated with the EI, and receiving a purchase request for the EI. The method branches to step 878 when the EI is not to be offered for sale. The method continues to step 876 when the EI is to be offered for sale where the processing module posts the EI in the marketplace. For example, the processing module updates the exchange item database to indicate that the EI is for sale.
The mother continues at step 878 where the processing module determines whether the EI has been sold. The determining includes one or more of receiving purchase transaction information, interpreting a request for purchase of the EI, and interpreting a status associated with the EI in the exchange item database. The method branches to step 882 when the EI has not been sold. The method continues to step 880 when the EI has been sold where the processing module processes the sale and updates information. For example, the processing module updates the exchange item database to indicate that the EI has been sold, the purchase amount, and identification of the (new) owner.
The method continues at step 882 where the processing module updates the conditions. For example, the processing module obtains updated date and time information, sports scores, stock market information, world events information, and weather information. With the conditions updated, utilization and sale of other exchange items may be affected as different use rules associated with the different exchange items may unable shifts in parameters associated with exchange items. For example, an additional discount for a particular branded exchange item may be enabled when a temperature value of a temperature condition is less than a low threshold value. As another example, a balance of another exchange item may be increased by 10% for a two-hour time frame when a local baseball team wins a game and the exchange item is associated with a brand of the local baseball team. Having updated the conditions, the method loops back to step 866
A method associated with the creation of the EI rule includes step 890 where a processing module (e.g., by a brand server, by a marketplace server) determines whether an exchange item (EI) rule has been invoked. The determining may be based on one or more of interpreting values of conditions in accordance with the EI rule, receiving a message indicating that the rule has been invoked, and detecting an activity associated with the invoking of the rule. The method branches to steps 892 and 894 when the EI rule has been invoked. The method branches to step 902 when the EI rule has not been invoked where the processing module determines whether the EI rule has changed. The determining may be based on one or more of interpreting a change flag, receiving a change message, observing activity associated with a change of the rule, and comparing a previous EI rule to the EI rule. The method continues to step 904 when the EI rule has not been changed where the processing module determines whether the EI rule has expired (e.g., detecting that an active timeframe associated with the EI rule has elapsed). The method loops back to step 890 when the EI rule has not expired.
When the EI rule has been invoked, the method continues at step 892 where the processing module notifies a current owner of the invoked EI rule (e.g., issuing a message to a brand server that established (i.e., owner) the rule) and the method continues at step 894 where the processing module updates the EI based on the invoked EI rule. The updating includes modifying a record of the EI in the marketplace server database immediately or upon receiving a permissions grant from the owner, modifying the record of the EI in the marketplace server database.
The method continues at step 896 where the processing module determines whether the EI rule has been revoked. The determining may be based on one or more of interpreting updated conditions associated with the EI rule and indicating that the EI rule has been revoked and receiving a message indicating that the EI rule has been revoked (e.g., from a brand server). The method loops back to step 890 when the EI rule has not been revoked. The method continues to steps 898 and 900 when the EI rule has been revoked. The method continues at step 898 where the processing module notifies the current owner of the revoked EI rule (e.g., issuing an EI revoked message) and updates the associated EI based on the revoked EI rule (e.g., updates the marketplace server database).
A method associated with the invoking of the EI rule includes step 906 where the processing module tracks conditions for exchange items of a rule set. For example, the processing module receives conditions data associated with a plurality of conditions types and maps the conditions data a plurality of exchange items associated with rules that rely on the conditions to activate a course of action. The method continues at step 908 where the processing module, per exchange item, determines when a condition conforms to a rule to invoke the rule. For example, the processing module indicates to invoke the rule when a condition of the rule meets a threshold level.
A method associated with the updating of the EI rule includes step 910 where the marketplace server takes control of the exchange item. The taking of control includes invoking a rule that includes granting updating authority for the marketplace server. With the authority to update the exchange item in the marketplace server database, the marketplace server may modify a rule, add a rule, delete a rule, add conditions associated with a rule, delete conditions associated with a rule, and modify conditions associated with a rule.
The method continues at step 912 where the marketplace server updates the exchange item. For example, the marketplace server recovers a portion (e.g., a single transaction blockchain including a ledger of all exchange items) of the marketplace server database and modifies the recovered portion (e.g., modifies the blockchain) to produce an updated portion of the marketplace server database. The method continues at step 914 where the marketplace server signs the updated exchange item. For example, the marketplace server utilizes a private key of a public/private key pair of the marketplace server to electronically sign the updated exchange item to produce a signature of the marketplace server. The method continues at step 916 where the marketplace server returns control of the signed updated exchange item. For example, the marketplace server stores the signed updated exchange item into the marketplace or database and pushes the signed updated exchange item to one or more entities of the exchange item marketplace network. For instance, the marketplace server sends the signed updated exchange item to a computing device associated with purchase of the exchange item. As another instance, the marketplace server sends the signed updated exchange item to a brand server associated with the exchange item. Such a signed updated exchange item is illustrated where exchange item serial number 5, that is associated with owner AA, includes conditions e3, f6, p5 that is associated with the exchange item 5, and that now follows a rule set 4.
In an example of operation of the establishing of the agreements and setting up of the exchange items, the setup (i.e., or set up) processing 936 of the marketplace server 18 establishes the agreement database 930. The establishing includes receiving agreement information and updating the agreement database 930 within the marketplace database 20. For example, the marketplace server 18 issues a query to one or more of the EI issuing server 920, another issuing server, a merchant server, another merchant server; and receives a query response. As another example, the marketplace server 18 receives an unsolicited message including the agreement information. Having received the agreement information, the marketplace server updates the agreement database 930. The agreement database 930 correlates issuer information, merchant information, and agreement information. For example, the agreement database 930 associates issuer A_1 with a merchant A_1_n as bound by an agreement aa (e.g., including one or more agreement points).
Having established the agreements, the marketplace server 18 facilitates setting up of the exchange items to include establishment of exchange item (EI) rules. An initiating entity establishes a first rule for a new exchange item. The initiating entity includes at least one of the EI issuing server 920 and the set up processing 936 of the marketplace server 18. The first rule is associated with establishment of a security approach to ensure that and subsequent rules associated with the EI can be trusted by all marketplace participants as time proceeds. For example, the EI issuing server 920 establishes trust information 954 to include a first contract block of a contract blockchain, where private/public key pairs are utilized to ensure trust as previously discussed with reference to
The initiating entity further establishes the new exchange item. For example, the EI issuing server 920 establishes EI information 950 (e.g., value, type, issuance date, expiration date, use parameters, etc.). The initiating entity further establishes content of the first rule, and further content of other rules as an EI rule set 952. For example, the EI issuing server 920 utilizes a fourth set of EI rules and an EI of serial number 5 for issuer B_K (e.g., identity of the EI issuing server 920) to include EI 05 info. The EI005 is to be for sale and is bound by a fourth set of EI rules which are associated with conditions e3, f6, p5 in accordance with use options of the issuer B_K. Having obtained the EI information 950 and the EI rule set 952, the set up processing 936 verifies the received EI information and set by exchanging set up verification 956 with the EI trusted module 922. For example, the EI trusted module 922 verifies the contract blockchain and sends an indication of a status of the verification to the marketplace server 18.
When the EI information 950 in the EI rule set 952 have been verified, set up processing 936 updates the exchange item database 934 of the marketplace database 20 with the EI information 950 in the EI rule set 952. For instance, the setup processing 936 establishes the role of the exchange item database 934 associated with the EI serial number 005. The set up processing 936 may further update the user database 932 to include a list of known users of the marketplace, a history of EI buying, selling, and using. For example, the set up processing 936 updates the user database 932 when the initial owner computing device 928 (e.g., owner AA) purchases the new EI by exchanging set up information 958 with the marketplace server 18. The initial owner computing device 928 updates a digital wallet 946 of the initial owner computing device 928 with an owner table. The owner table includes one or more of a list of EI serial numbers, and for each EI, an identifier of an issuer, associated EI information, use options, EI rules associated with the EI, and conditions associated with the EI. Alternatively, or in addition to, the marketplace server maintains a copy of the owner table in the marketplace database 20.
In an example of operation of the processing of the sale of the EI serial number 005 by the initial owner computing device 928 (e.g., owner AA) the EI buyer computing device 926 (e.g., owner DZ), the sale processing 938 of the marketplace server 18 exchanges sale information 966 with the initial owner computing device 928, where the sale information 966 includes one or more of the EI serial number 005, a sale price, use options, a commission amount (e.g., to the marketplace), and credit information (e.g., a 05 credit of generic value usable in the marketplace to purchase another EI or to be converted into another form of payment). The initial owner computing device 928 updates the digital wallet 946 to indicate that the EI serial number 005 has been sold and that the 05 credit is available.
The sale processing 938 further exchanges sale verification 968 with the EI trusted module 922. For example, the EI trusted module 922 verifies the contract blockchain and a transaction blockchain associated with the EI to ensure that the sale is within sale allowance parameters associated with the EI as imposed by one or more of an agreement, and EI rule, conditions, and use options. When verified, the EI trusted module 922 issues the sale verification 968 to the sale processing 938 indicating that the sale is verified.
The sale processing 938 further exchanges purchase information 970 with the EI buyer computing device 926, such that the EI buyer computing device 926 updates the digital wallet 944 indicating that owner DZ has the EI serial number 005. Having processed the sale of the EI 005, the sale processing 938 updates the marketplace database 20 indicating that the EI serial 005 is now associated with owner DZ and is not currently for sale.
In an example of operation of the use of the EI, the EI buyer computing device 926 obtains EI info from the digital wallet 944 to issue buyer use information 976 to the marketplace server 18 when desiring to utilize the exchange item (e.g., EI serial number 005) with a merchant associated with the merchant server 924 for purchase of goods and/or services. When receiving the buyer use information 976, the use processing 940 of the marketplace server 18 verifies the use by exchanging use verification 978 with the EI trusted module 922. The use verification 978 includes one or more of the buyer use information 976 and an associated row of the exchange item database 934 associated with the exchange item (e.g., the row associated with the exchange item serial number 005). For example, the EI trusted module 922 verifies that the use of the EI compares favorably with the associated rules, conditions, and use options.
When receiving favorable use verification 978, the use processing 940 exchanges merchant use information 980 with the merchant server 924 to complete the use of exchange item. Alternatively, the marketplace server 18 receives the merchant use information 980 from the merchant server 924 via the EI buyer computing device 926 as part of the buyer use information 976 (e.g., a secure blockchain element is generated by the merchant server 924 and communicated directly to the EI buyer computing device 926).
The merchant use information 980 includes one or more of the buyer use information 976, the use verification 978, and any additional information to complete the use of the EI. Upon completion of the use of the EI, the use processing 940 updates the exchange item database 934 indicating that the EI has been utilized (e.g., indicating an amount of an outstanding balance utilized and a remaining available balance etc.). Alternatively, or in addition to, the use processing 940 performs a merchant verification process in accordance with a rule associated with the exchange item. For example, the use processing 940 extracts security information from the merchant use information 980, exchanges use information 978 with the EI trusted module 922, and interprets a use verification 978 response from the EI trusted module 922 to determine whether the merchant server 924 is verified (e.g., non-fraudulent). The EI trusted module 922 may verify the merchant server 924 by a variety of approaches including accessing a database of fraudulent merchants, invoking a rule of an associated exchange item to test a plurality parameters associated with the merchant use information 980, and requesting that the merchant server 924 electronically sign a message to verify that the merchant server 924 holds a correct private key associated with a previously verified merchant server 924.
In an example of operation of the processing of the rules, the rule processing 942 of the marketplace server 18 records conditions for a plurality exchange items. A condition of the conditions for the plurality of exchange items further includes one of a range of time, a range of dates, a geographic location, a building address, a list of items, a user tendency profile, and a user loyalty profile. For example, the marketplace server 18 obtains the condition from a corresponding condition source.
For an exchange item of the plurality of exchange items, where the exchange item has a quantifiable value (e.g., valid tender, offered something formally in writing, offered a sum for a settlement, same as money, offer made to settle something), a serial number, and a current owner, the rule processing 942 determines whether a corresponding condition of the exchange item is compliant with one or more rules of an applicable set of rules (e.g., a contract regarding the exchange item from the issuer, where a set of rules is utilized for each EI, or for a group of EIs, for each owner, by brand, by retailer, etc.). The determining includes utilizing a sliding scale of compliance (e.g., conditional chaining) based on one or more of a user profile, exchange item information, an exchange item issuer, limited exchange item use, and timing of use. For example, the rule processing 942 obtains information with regards to conditions and EI rules from the exchange item database 934 and interprets conditions data in accordance with the EI rules to determine the compliance. For example, the rule processing 942 indicates that a weather rule is compliant when a temperature condition indicates a temperature value that is greater than a temperature threshold value associated with the weather rule.
The rule processing 942 may verify the compliance with the EI rule by obtaining issuer rule information 986 from the EI issuing server 920 associated with the EI and by further verifying compliance by exchanging rule verification 990 with the EI trusted module 922. The verifying of compliance further includes verifying a security scheme (e.g., contract blockchain or the EI rules) and by checking that the EI rule compares favorably to the issuer rule information 986 from the EI issuing server 920.
The rule processing 942 may update the applicable set of rules based on one or more of a rule changing, a rule expiring, and a new rule being added to the set. For example, the rule processing 942 updates the exchange item database 934 and sends owner rule info 988 to the EI buyer computing device 926 to indicate an EI rule change associated with a particular EI when current conditions and a previous rule indicate changing the rule when the conditions are compliant.
The rule processing 942 may further determine a specific use as the one or more rules of the applicable rule set (e.g., for a specific product, a specific store, etc.). For example, the rule processing 942 identifies raising a discount level for the exchange item in accordance with the EI rule as the specific use in accordance with the EI rule and favorable conditions to alter the discount level. Alternatively, or in addition to, the rule processing 942 determines a specific time frame as the one or more rules of the applicable rule set (e.g., for a set period of time, a day, etc.). For example, the rule processing 942 identifies a two-hour time window for the raised discount level for the exchange item in accordance with the one or more rules.
When the corresponding condition of the exchange item is compliant with the one or more rules, the rule processing 942 establishes a secure communication with a computing device affiliated with a current owner (e.g., of the exchange item and/or of the contract blockchain) to take control of the exchange item (e.g., to update an exchange item record of the exchange item). Having control includes holding a private key associated with modifying a blockchain associated with the exchange item. For example, the rule processing 942 exchanges a secure owner rule information 988 with the EI buyer computing device 926 associated with an exchange item serial number 005, where the rule processing 942, in accordance with a security rule, is allowed to modify the contract blockchain with regards to the EI rules.
While having control over the exchange item, the rule processing 942 securely modifies the quantifiable value of the exchange item based on the one or more rules to produce a modified exchange item. For example, the rule processing 942 adds another contract block to the contract blockchain, where the additional contract block includes a modified exchange item as modified exchange item info serial number 005. The modifying of the quantifiable value includes increasing the quantifiable value for the specific use when the specific use is utilized as the one or more rules of the applicable rule set and securely modifying the quantifiable value of the exchange item in accordance with the blockchain protocol.
Having modified the quantifiable value of the modified exchange item, the rule processing 942 sends a notification message (e.g., owner rule information 988) to the computing device (e.g., the EI buyer computing device 926) regarding the increased quantifiable value and the specific use. Having received the notification message, the EI buyer computing device 926 stores the (modified) exchange item in accordance with the blockchain protocol (e.g., stores the contract blockchain including the new contract block in the digital wallet 944).
The modifying of the quantifiable value may further include increasing the quantifiable value for use during the specific time frame when the specific time frame is utilized as the one or more rules of the applicable rule set (e.g., an increase discount level for the next two hours). Having modified the quantifiable value, the rule processing 942 sends another notification message to the computing device regarding the increased quantifiable value and the specific time frame.
While having control over the exchange item, the rule processing 942 further prevents the computing device or another computing device from accessing the exchange item. For example, the rule processing 942 issues owner rule information 988 to the EI buyer computing device 926 indicating that the exchange item is not to be utilized while being modified. Alternatively, or in addition to, the rule processing 942 updates the exchange item database 934 indicating that the exchange item is not to be accessed while being modified. When completing the modification, the rule processing 942 releases, via the secure communication, control of the modified exchange item to the computing device affiliated with the current owner. For example, the rule processing 942 issues yet another owner rule information 988 to the EI buyer computing device 926 indicating that the exchange item has been updated and released.
With the exchange item updated, and when the specific time frame expires (e.g., when utilized) and the modified exchange item is unused (e.g., the EI buyer computing device 926 has not used the modified exchange item at all), the rule processing 942 facilitates reverting of the exchange item. The reverting of the exchange item includes one or more of establishing another secure communication with the computing device affiliated with exchange item to take control of the modified exchange item and while having control over the modified exchange item, decreasing the increased quantifiable value to the quantifiable value to produce a reverted exchange item, preventing the computing device or another computing device from accessing the exchange item, releasing, via the other secure communication, control of the reverted exchange item to the computing device affiliated with the current owner, and sending another notification message to the computing device regarding the reverted exchange item.
Alternatively, when the specific time frame expires, and the modified exchange item was used but did not exhaust the quantifiable value, the rule processing 942 facilitates producing a further modified EI. The facilitating to produce the further modified EI includes one or more of identifying another rule of the applicable set of rules to further modify the modified exchange item, establishing another secure communication with the computing device affiliated to take control of the modified exchange item, and while having control over the modified exchange item, the rule processing 942 increases a remaining quantifiable value to produce a further modified exchange item, prevents the computing device or another computing device from accessing to the modified exchange item, releases, via the other secure communication, control of the further modified exchange item to the computing device affiliated with the current owner, and sends another notification message to the computing device regarding the further modified exchange item.
With the modified exchange item, the EI buyer computing device 926 may utilize the modified exchange item in conjunction with a purchase transaction from a merchant. For example, the EI buyer computing device 926 sends a use request to another server (e.g., a merchant server) regarding the modified exchange item (e.g., to utilize the modified EI for the purchase transaction). Having received the use request, the other server sends a use notification to the marketplace server 18. Having received the use notification, the rule processing 942 of the market place over 18 establishes a second secure communication with the computing device affiliated with the current owner to take control of the modified exchange item (e.g., exchanges owner rule information 988 with the EI buyer computing device 926).
While having control over the exchange item, the marketplace server 18 securely adjusts the quantifiable value of the exchange item based on the use notification to produce an adjusted exchange item (e.g., decrements a remaining balance by an amount of the purchase transaction and updates one or more of a transaction blockchain and the contract blockchain) and prevents the computing device, the other server, or other computing devices from accessing the exchange item. Once modified, the marketplace server 18 releases, via the second secure communication, control of the adjusted exchange item to the computing device affiliated with the current owner.
To ensure favorable security, a controlling entity desiring to modify the blockchain must be associated with control of the blockchain as indicated by the blockchain control field of the exchange item database 934. The controlling entity may change from one entity to another during the EI lifecycle and may further be constrained as indicated by the EI rules. For example, a particular blockchain may be controlled by the EI issuer in the beginning and later controlled by the marketplace server in accordance with the EI rules established by the EI issuer. As another example, the blockchain may be controlled by the merchant server to update rules and conditions to support a particular promotion as allowed by the original and current EI rules.
A most recent revision of a particular blockchain may be temporarily stored in one or more entities of the exchange item marketplace as indicated by the blockchain location field. As such, the controlling entity may utilize the exchange item database 934 to identify the entity where the blockchain is temporarily stored to gain access to the blockchain for modification in accordance with the rules and conditions.
The contract blockchain includes one or more contract blocks representing changes to rules and/or conditions of the EI of the EI information. For example, the contract blockchain includes a complete contract blockchain for substantially all of the rules and/or conditions changes. As another example, the contract blockchain includes at least one contract block associated with the transaction block. Alternatively, or in addition to, the contract blockchain is maintained separately and is not included within the transaction block. Further alternatively, a single combined transaction and contract blockchain is maintained as one entity.
Each contract block includes a security bridge from a last block to this block, a contract package (from a last contract block to this contract block), and a signature by a current rules owner over the contract package. Each contract package includes at least one next owner public key (e.g., associated with an exchange item marketplace entity expected to be a next owner of the contract blockchain), and contract information. The contract information includes one or more of EI rules, conditions, use options, EI information, agreements, merchant identifiers, issuer identifier, EI serial number, owner identifier, an offer for sale indicator, etc. The signature over the contract packages created by a current owner of the contract blockchain signing the contract package utilizing a private key of a public/private key pair associated with the current owner of the contract blockchain. The or more blockchains may be verified from time to time utilizing industry-standard mining approaches and are applicable to both proof of work, proof of stake, and other hybrid mining techniques.
When the corresponding condition of the exchange item is compliant with the one or more rules, the method continues at step 1004 where the processing module establishes a secure communication with a computing device affiliated with the current owner to take control of the exchange item. For example, the processing module accesses a contract blockchain currently possessed by the computing device.
While having control over the exchange item, the method continues at step 1006 where the processing module securely modifies the quantifiable value of the exchange item based on the one or more rules to produce a modified exchange item. The modifying may include modifying the quantifiable value by increasing the quantifiable value for the specific use when the specific use is utilized as the one or more rules of the applicable rule set and securely modifying the quantifiable value of the exchange item in accordance with a blockchain protocol (e.g., of the contract blockchain). The modifying may further include sending a notification message to the computing device regarding the increased quantifiable value and the specific use and storing, by the computing device, the exchange item in accordance with the blockchain protocol. The modifying of the quantifiable value may further include increasing the quantifiable value for use during the specific time frame (e.g., an increased discount for the next two hours) when the specific time frame is utilized as the one or more rules of the applicable rule set and sending a notification message to the computing device regarding the increased quantifiable value and the specific time frame. While having control over the exchange item, the processing module prevents the computing device or another computing device from accessing the exchange item (e.g., marking the modified exchange item as not accessible).
The method continues at step 1008 where the processing module releases, via the secure communication, control of the modified exchange item to the computing device affiliated with the current owner. For example, the processing module marks the modified exchange item as accessible enabling use of the modified exchange item by the computing device (e.g., to make a purchase transaction). When the specific time frame expires (e.g., two hours has elapsed), and the modified exchange item was used but did not exhaust the quantifiable value, the method branches to step 1012. When the specific time frame expires and the modified exchange item is unused, the method continues to step 1010.
When the specific time frame expires and the modified exchange item is unused, the method continues at step 1010 where the processing module facilitates producing a reverted EI. The facilitating includes establishing another secure communication with the computing device affiliated to take control of the modified exchange item. While having control over the modified exchange item, the processing module decreases the increased quantifiable value to the quantifiable value to produce a reverted exchange item, prevents the computing device or another computing device from accessing the exchange item, releases, via the other secure communication, control of the reverted exchange item to the computing device affiliated with the current owner, and sends another notification message to the computing device regarding the reverted exchange item. The method branches to step 1014.
When the specific time frame expires, and the modified exchange item was used but did not exhaust the quantifiable value, the method continues at step 1012 where the processing module facilitates producing a further modified EI. The facilitating of producing the further modified EI includes identifying another rule of the applicable set of rules to further modify the modified exchange item and establishing another secure communication with the computing device affiliated to take control of the modified exchange item. While having control over the modified exchange item, the processing module increases a remaining quantifiable value to produce a further modified exchange item, prevents the computing device or another computing device from accessing to the modified exchange item, releases, via the other secure communication, control of the further modified exchange item to the computing device affiliated with the current owner, and sends another notification message to the computing device regarding the further modified exchange item.
The method continues at 1014 where the computing device sends a use request to another server regarding the modified exchange item (e.g., to utilize the modified exchange item for a purchase transaction). The method continues at step 1016 where the other server sends a use notification to the other server (e.g., including information with regards to the purchase transaction). The method continues at step 1018 where the processing module of the server establishes a second secure communication with the computing device affiliated with the current owner to take control of the modified exchange item.
While having control over the exchange item, the method continues at step 1020 where the processing module of the server securely adjusts the quantifiable value of the exchange item based on the use notification to produce an adjusted exchange item (e.g., decrements a remaining balance by an amount of the purchase transaction). The adjusting may further include preventing the computing device, the other server, or other computing devices from accessing the exchange item during the adjusting. The method continues at step 1022 where the processing module of the server, and via the second secure communication, releases control of the adjusted exchange item to the computing device affiliated with the current owner.
The method described above in conjunction with the processing can alternatively be performed by other modules of the exchange item marketplace network or by other devices. In addition, at least one memory section (e.g., a computer readable memory, a non-transitory computer readable storage medium organized into a first memory section, a second memory section, a third memory section, a fourth memory section, etc.) that stores operational instructions can, when executed by one or more processing modules of one or more computing devices (e.g., one or more servers) of the exchange item marketplace network, cause the one or more computing devices to perform any or all of the method steps described above.
In an example of operation of the transferring the secure custody of the exchange item between entities, the marketplace server 18 (e.g., the server) establishes an initial validity of the exchange item that includes data regarding a quantifiable value, a serial number, and issuance information, where the initial validity authenticates the exchange item and the data. The issuance information includes one or more of issuer identity, and issuance date, and expiration time frame, EI rules, and use parameters. The establishing may include receiving a plurality of exchange items from the EI issuing server 920, where the plurality of exchange items includes the exchange item, and establishing the initial validity of the exchange item with the EI issuing server 920. For example, the set up processing 936 receives EI information 950 and an EI rule set 952 from the EI issuing server 920, where the EI issuing server 920 issues trust information 954 (e.g., a first contract block of the contract blockchain) to the EI trusted module 922 while generating the EI information 950 and the EI rule set 952. Having received the EI information 950 and the EI rule set 952, the set up processing 936 exchanges set up verification 956 with the EI trusted module 922 to validate the EI information 950 and the EI rule set 952.
Having established the initial validity of the exchange item, the marketplace server 18 executes a secure custody protocol to establish that the initial owner computing device 928 (e.g., a first computing device) of the exchange item marketplace network (e.g., data communication system) has secure custody of the exchange item and to maintain validity of the exchange item. The secure custody protocol may further include one or more of a chain of custody mechanism (e.g., the blockchains), exchange item modification restrictions for computing devices of the data communication system (e.g., the initial owner computing device 928, the EI buyer computing device 926, the merchant server 924), and exchange item modification rights for servers of the data communication system. For example, the sale processing 938 exchanges set up information 958 with the initial owner computing device 928 (e.g., a request to purchase the exchange item, confirmation of sale, the EI info 950, one or more of the transaction blockchain and the contract blockchain).
Having executed the secure custody protocol, in response to an exchange item transfer and in accordance with the secure custody protocol, the marketplace server 18 facilitates transfer of the secure custody of the exchange item from the first computing device (e.g., the initial owner computing device 928) to the server or to a second computing device (e.g., the EI buyer computing device 926) of the data communication system. Such transfer supports one or more of a sale of the exchange item, use of the exchange item for a purchase transaction with a merchant associated with the merchant server 924, and modification of the exchange item in accordance with the EI rule set 952.
The transferring the secure custody of the exchange item from the initial owner computing device 928 to the EI buyer computing device 926 includes creating, by the sale processing 938, an offer for sale digital file for the exchange item in response to an offer for sale request from the initial owner computing device 928 and writing the offer for sale digital file for the exchange item to the marketplace database 20 (e.g., a virtual marketplace database) that includes a user interface for computing devices of the data communication system to view offer for sale digital files for a plurality of exchange items. The transferring further includes the sale processing 938 receiving purchase information 970 that includes a request to purchase the exchange item from the EI buyer computing device 926 and upon successful execution of the purchase, transferring the secure custody of the exchange item to the EI buyer computing device 926. For example, the sale processing 938 exchanges sale verification 968 with the EI trusted module 922 to update the transaction blockchain to indicate that the EI buyer computing device 926 is purchasing the exchange item from the initial owner computing device 928.
The transferring the secure custody of the exchange item from the first computing device to the second computing device may further include the sale processing 938 transferring, in response to another exchange item transfer and in accordance with the secure custody protocol, the secure custody of the exchange item from the second computing device to the marketplace server 18 or to a third computing device of the data communication system. The transferring the secure custody of the exchange item from the first computing device to the second computing device may still further include the initial owner computing device 928 sending a request to use the exchange item to the use processing 940 of the marketplace server 18, where the request to use the exchange item identifies the second computing device. When the use is authorized (e.g., the use processing 940 verifies that such use is authorized in accordance with the EI rule set 952), the use processing 940 transfers the secure custody of the exchange item to the second computing device for the second computing device to execute the use, where the second computing device changes the quantifiable value of the exchange item to produce a use modified exchange item (e.g., modified EI info 1030), and the use processing 940 transfers secure custody of the use modified EI info 1030 from the second computing device to the first computing device.
When transferring the secure custody of the exchange item from the initial owner computing device 928 (e.g., the first computing device) to the EI buyer computing device 926 (e.g., the second computing device), the rule processing 942 of the marketplace server 18 determines whether a change to the data of the exchange item occurred while the exchange item is in the secure custody of the second computer. For example, the rule processing 942 indicates the change to the data when the use processing 940 receives merchant use information 980 from the merchant server 924 in response to the EI buyer computer device 926 issuing buyer use information 976 to the use processing 940 to facilitate the purchase transaction with the merchant server 924.
When the change to the data of the exchange item occurred while the exchange item is in the secure custody of the second computer, the use processing 940 of the marketplace server 18 determines whether the exchange item is exhausted (e.g., a remaining balance of zero). When the exchange item is exhausted, the use processing 940 retires the exchange item (e.g., removes the exchange item from the marketplace database 20 and/or issues retirement information to a current owner of exchange item.
When the exchange item is in the secure custody of the server, the rule processing 942 of the marketplace server 18 may modify the data of the exchange item to produce a modified exchange item. The modifying of the data of the exchange item includes identifying a set of rules regarding the exchange item, where the set of rules includes one or more rules, where a rule of the set of rules includes an amount of data change and one or more conditions on when to apply the amount of change. The modifying further includes the rule processing 942 determining that a condition involving the first computing device conforms to the one or more conditions and when the condition involving the first computing device conforms to the one or more conditions, the rule processing 942 modifies the data of the exchange item in accordance with the amount of change (e.g., updates the marketplace database 20). Having modified the data of the exchange item, the rule processing 942 transfers secure custody of the modified exchange item to the initial owner computing device 928 device in accordance with the secure custody protocol.
The method continues at step 1102 where the processing module executes a secure custody protocol to establish that a first computing device of the data communication system has secure custody of the exchange item and to maintain validity of the exchange item. For example, the processing module generates a secure transaction block of a transaction blockchain, where the secure transaction block indicates that the first computing device has secure custody.
The method continues to step 1104 where the processing module transfers, in response to an exchange item transfer and in accordance with the secure custody protocol, the secure custody of the exchange item from the first computing device to the server or to a second computing device of the data communication system (e.g., for a sale, a purchase, or a modification). The method branches to step 1112 when transferring to the server. When transferring to the second computing device, the transferring the secure custody of the exchange item from the first computing device to the second computing device includes creating an offer for sale digital file for the exchange item in response to an offer for sale request from the first computing device the offer for sale digital file for the exchange item to a virtual marketplace database that includes a user interface for computing devices of the data communication system to view offer for sale digital files for a plurality of exchange items, receiving a request to purchase the exchange item from the second computing device, and upon successful execution of the purchase, transferring the secure custody of the exchange item to the second computing device.
The transferring the secure custody of the exchange item from the first computing device to the second computing device may further include transferring, in response to another exchange item transfer and in accordance with the secure custody protocol, the secure custody of the exchange item from the second computing device to the server or to a third computing device of the data communication system. The transferring the secure custody of the exchange item from the first computing device to the second computing device may still further include sending, by the first computing device, a request to use the exchange item to the server, where the request to use the exchange item identifies the second computing device. When the use is authorized, processing module transfers the secure custody of the exchange item to the second computing device for the second computing device to execute the use, where the second computing device changes the quantifiable value of the exchange item to produce a use modified exchange item, and transfers secure custody of the use modified exchange item from the second computing device to the first computing device.
When transferring the secure custody of the exchange item from the first computing device to the second computing device, the method continues at step 1106 where the processing module determines whether a change to the data of the exchange item occurred while the exchange item is in the secure custody of the second computing device (e.g., a lowering of a remaining balance based on usage of the exchange item). When the change to the data of the exchange item occurred while the exchange item is in the secure custody of the second computing device, the method continues at step 1108 where the processing module determines whether the exchange item is exhausted (e.g., remaining balance has reached zero). When the exchange item is exhausted, the method continues at step 1110 where the processing module retires the exchange item.
When the exchange item is in the secure custody of the server, the method continues at step 1112 or the processing module modifies the data of the exchange item to produce a modified exchange item. The modifying the data of the exchange item includes identifying a set of rules regarding the exchange item, where the set of rules includes one or more rules, where a rule of the set of rules includes an amount of data change and one or more conditions on when to apply the amount of change, determining that a condition involving the first computing device conforms to the one or more conditions, and when the condition involving the first computing device conforms to the one or more conditions, modifying the data of the exchange item in accordance with the amount of change. The method continues at step 1114 where the processing module transfers secure custody of the modified exchange item to the first computing device in accordance with the secure custody protocol.
The method described above in conjunction with the processing can alternatively be performed by other modules of the exchange item marketplace network or by other devices. In addition, at least one memory section (e.g., a computer readable memory, a non-transitory computer readable storage medium organized into a first memory section, a second memory section, a third memory section, a fourth memory section, a fifth memory section etc.) that stores operational instructions can, when executed by one or more processing modules of one or more computing devices (e.g., one or more servers) of the exchange item marketplace network, cause the one or more computing devices to perform any or all of the method steps described above.
The enterprise storage 1122 includes one or more of the agreement database 930 of
The set up module 1126 functions to initially validate exchange items and create records in the exchange item database 934 for validated exchange items, where each of the exchange items includes data regarding a quantifiable value, a serial number, and issuance information.
The sale module 1128 functions to securely transfer a selected exchange item from the first computing device to the second computing device. The use module 1130 functions to securely apply the selected exchange item to a closed loop digital transaction in accordance with an agreement of the agreements database 930. The rule application module 1132 functions to securely modify the data of the selected exchange item in accordance with an applicable set of rules from the rules database 1120. Examples of operation of the enterprise server 1124 are discussed in greater detail below.
The enterprise storage 1122 further functions to store the user database 932, where the user database 932 includes one or more of a user identifier field (e.g., identified person and associated computing devices), an exchange item buying information field; (e.g., which EIs the user buys), and exchange item use information field (e.g., how much, how often, and what types of EIs the user uses), and an exchange item selling information field.
To facilitate offering exchange items for sale, the processing module of the enterprise server 1124 accesses a record in the user database 932 of a user associated with a computing device, accesses one or more of the exchange item database, the agreements database, and the rules database to identify one or more exchange items of interest to the user, and sends, via the network interface, a message to the computing device regarding the one or more exchange items of interest.
When acquiring an exchange item, the computing device of the plurality of computing devices stores a user exchange item database (e.g., a portion of the exchange item database 934 that is pertinent to the user and computing device) that includes one or more of an exchange item identifier field, an issuer identifier field, an exchange item information field, a use options field, a control field, a location field, a status field, and a transaction field. The exchange item database 934 includes one or more records, where each record includes one or more of an exchange item identifier field, an issuer identifier field, a current owner identifier field, an exchange item information field (e.g., value, type, issuance date, expiration date, use parameters), a conditions field (e.g., tracks conditions of an owner regarding potential applicability of rules), a rules identifier field (e.g., identifies one or more applicable rule sets), an offer for sale field (e.g., an indication that current owner is offering the EI for sale, doesn't prohibit current owner from using EI), a use options field (e.g., identifies which merchants will accept the EI as a form of payment, this is determined based on content of the agreement database 930), a control field (e.g., identifies the entity that currently has the right to use or modify the EI), a location field (e.g., identifies the entity that currently has physical possession of the EI, which may be different than the entity that has control, for example, the server may have physical possession and a computing device may have control), a status field (e.g., identify the status of the EI such as active, inactive, valid, questionable validity, exhausted, expired, etc.), and a transaction field (e.g., a record of the transaction history of the EI, built into blockchain). Each field may include sub-fields to accommodate various pieces of information being recorded.
The agreements database includes one or more of an issuer identifier field, an exchange item type field (e.g., identifies the types of EI that are part of the agreement), a recipient entity identifier field (e.g., identifies the entities that will accept the EI as a form of payment), an agreement identifier field (e.g., agreement between issuer and recipient entity on use of EI), and a rules identifier field (e.g., if rules exist for EI, do they apply for use with the recipient, may vary from recipient to recipient). The rules database includes one or more of an issuer identifier field, an exchange item type field (e.g., per issuer), a rule set field (e.g., includes rules for a set of rules: discount, conditions to be met, etc.), and a rules applicability field (e.g., for an EI type, does the rule set apply or not).
When adding a new exchange item to the data communication system, the set up module 1126 establishes establish, via the network interface and the network 24, a secure communication link with the trusted issuing server 1134, where the issuing server 1134 performs one or more of creating the EI to put directly into the exchange item database, providing on-the-fly creation at request of a user or merchant, providing the EI as a location based promotion, and providing the EI as a user based promotion, etc. Having established the link, the set up module 1126 receives, via the network interface and the network 24, the data of the exchange item from the trusted issuing server 1134 in accordance with a secure custody protocol (e.g., utilizing a contract blockchain). Having received the data, the set up module 1126 establishes the enterprise server 1124 as having secure custody of the exchange item (e.g., as a current owner as noted within the contract blockchain). Having established the secure custody, the set up module 1126 creates a record in the exchange item database 934 for the exchange item.
When the exchange item is to be sold to a computing device, the sale module 1128 receives, via the network interface and the network 24, a request to sell a particular exchange item for a first computing device (e.g., computing device 1). Having received the request, the sale module 1128 verifies that the first computing device has secure custody of the particular exchange item in accordance with the secure custody protocol (e.g., verifies a signature of the computing device 1). When the first computing device has secure custody of the particular exchange item, the sale module 1128 verifies the data of the exchange item (e.g., verifies with the trusted issuing server 1134, verifies with the exchange item database 934, verifies a signature over the data). When the data of the exchange item is verified, the sale module 1128 adds an offer for sale digital record for the particular exchange item in the network-based virtual exchange item marketplace (e.g., indicates for sale in the exchange item database 934).
When the exchange item is to be sold from the first computing device to the second computing device, the sale module 1128 receives, via the network interface and the network 24, a request to purchase a particular exchange item from the second computing device (e.g., computing device 2) and authenticates the second computing device. When the second computing device is authenticated, the sale module 1128 transfers secure custody of the particular exchange item from the first computing device to the second computing device in accordance with the secure custody protocol (e.g., facilitates modification of the contract blockchain to indicate that the computing device 2 is the new owner), and removes the offer for sale digital record for the particular exchange item from the network-based virtual exchange item marketplace (e.g., updates the exchange item database 934).
When a computing device (e.g., computing device 2) utilizes an exchange item in a purchase transaction (e.g., a closed loop digital transaction), the use module 1130 receives, via the network interface and the network 24 from a computing device, a request to use the exchange item in a particular closed loop digital transaction with a recipient entity server (e.g., the merchant server 924). Having received the request, the use module 1130 accesses the agreements database 930 to determine whether an agreement exists between an issuing server (e.g., the trusted issuing server 1134) of the particular exchange item and the recipient entity server. When the agreement exists, the use module 1130 determines whether the particular closed loop digital transaction is in accordance with the agreement (e.g., user is allowed, the particular type of transaction is allowed, rules and conditions apply, etc.). When the particular closed loop digital transaction is in accordance with the agreement, the use module 1130 authorizes the particular closed loop transaction. When the agreement does not exist or the particular closed loop digital transaction is not in accordance with the agreement, use module 1130 denies the particular closed loop transaction.
From time to time, the rule application module 1132 considers modifying the data of the exchange item (e.g., based on one or more of interpreting a schedule, receiving a request, detecting a change in a condition). When considering the modifying of the data, the rule application module 1132 obtains condition information of a computing device having secure custody of a particular exchange item (e.g., condition from user profile and history provides the condition information, physical location, environmental conditions, etc.). The obtaining includes one or more of identifying a condition source, interpreting condition data from the identified condition source, receiving the condition information, performing a lookup, and generating the condition information based on condition data.
Having obtained the condition information, the rule application module 1132 accesses rules of the applicable set of rules associated with the particular exchange item from the rules database 1120. Having accessed the rules, the rule application module 1132 compares the condition information with the rules of the applicable set of rules. When the condition information compares favorably with the rules of the applicable set of rules, the rule application module 1132 obtains secure custody of the particular exchange item from the computing device in accordance with the secure custody protocol (e.g., physically take custody by a data transfer or update the exchange item database 934 to indicate that the enterprise server 1124 has secure custody). While having secure custody, the rule application module 1132 modifies the data of the particular exchange item in accordance with the rules of the application set of rules to produce a modified exchange item and transfers secure custody of the modified exchange item to the computing device.
The method continues at step 1142 where the processing module initially validates exchange items and creates records in the exchange item database for validated exchange items, where each of the exchange items includes data regarding a quantifiable value, a serial number, and issuance information. The initially validating the exchange items and creating records in the exchange further includes establishing a secure communication link with a trusted issuing server, receiving the data of an exchange item from the issuing server in accordance with a secure custody protocol, establishing the enterprise server as having secure custody of the exchange item, and creating a record in the exchange item database for the exchange item.
The method continues to step 1144 where the processing module securely transfers a selected exchange item from a first computing device to a second computing device in accordance with an offer for sale of the selected exchange item. The secure transferring of the selected exchange item from the first computing device to the second computing device in accordance with the offer for sale of the selected exchange item further includes a variety of approaches. In a first approach, the processing module receives a request to sell the selected exchange item from the first computing device, and verifies that the first computing device has secure custody of the particular exchange item in accordance with a secure custody protocol. When the first computing device has secure custody of the particular exchange item, the processing module verifies the data of the exchange item. When the data of the exchange item is verified, the processing module adds an offer for sale digital record for the particular exchange item in a network-based virtual exchange item marketplace (e.g., an exchange item database).
In a second approach to the securely transferring the selected exchange item from the first computing device to the second computing device in accordance with the offer for sale of the selected exchange item, the processing module receives a request to purchase a particular exchange item from the second computing device, and authenticates the second computing device. When the second computing device is authenticated, the processing module transfers secure custody of the particular exchange item from a first computing device to the second computing device in accordance with a secure custody protocol and removes an offer for sale digital record for the particular exchange item from the network-based virtual exchange item marketplace (e.g., from the exchange item database).
The method continues at step 1146 where the processing module securely applies the selected exchange item to a closed loop digital transaction between two computing entities (e.g., computing device or server) in accordance with an agreement of the agreements database. The securely applying the selected exchange item to the closed loop digital transaction further includes receiving, from a computing device, a request to use an exchange item in a particular closed loop digital transaction with a recipient entity server, and accessing the agreements database to determine whether an agreement exists between an issuing server of the particular exchange item and the recipient entity server. When the agreement exists, the processing module determines whether the particular closed loop digital transaction is in accordance with the agreement. When the particular closed loop digital transaction is in accordance with the agreement, the processing module authorizes the particular closed loop transaction. When the agreement does not exist or the particular closed loop digital transaction is not in accordance with the agreement, the processing module denies the particular closed loop transaction.
The method continues at step 1148 where the processing module securely modifies the data of the selected exchange item in accordance with an applicable set of rules from the rules database. The securely modifying of the data of the selected exchange item further includes obtaining condition information of a computing device having secure custody of a particular exchange item, accessing rules of the applicable set of rules associated with the particular exchange item from the rules database, and comparing the condition information with the rules of the applicable set of rules. When the condition information compares favorably with the rules of the applicable set of rules, the processing module obtains secure custody of the particular exchange item from the computing device in accordance with secure custody protocol. While having secure custody, the processing module modifies the data of the particular exchange item in accordance with the rules of the application set of rules to produce a modified exchange item and transfers secure custody of the modified exchange item to the computing device.
The method described above in conjunction with the processing can alternatively be performed by other modules of the exchange item marketplace network or by other devices. In addition, at least one memory section (e.g., a computer readable memory, a non-transitory computer readable storage medium organized into a first memory section, a second memory section, a third memory section, a fourth memory section, a fifth memory section etc.) that stores operational instructions can, when executed by one or more processing modules of one or more computing devices (e.g., one or more servers) of the exchange item marketplace network, cause the one or more computing devices to perform any or all of the method steps described above.
The EI information 950 includes an exchange item serial number as originally issued by at least one of the brand server 26 of
Having received the EI info 950, the set up processing 936 of the marketplace server 18 establishes one or more security parameters (e.g., hereafter interchangeably referred to as EI security parameters 1290 or security parameters) for the exchange item, where the exchange item includes an exchange item data file having a quantifiable value, a serial number (e.g., a static identifier), and issuance information (e.g., issuer identity, an issuance date, an expiration time frame, EI rules, use parameters). The one or more security parameters includes one or more of a secret key, a time interval truncation function (i.e., interchangeably referred to as a time interval increment), a generator algorithm identifier (ID) to identify one of a plurality of generator algorithms, and an arithmetic algorithm identifier (i.e., interchangeably referred to as a combiner algorithm ID) to identify one or more of a plurality of arithmetic algorithms (e.g., logical and/or mathematical functions). The establishing may be based on one or more of a predetermination, system registry information, a security requirement, and a request. The generating of the EI security parameters 1290 includes one or more of generating the secret key (e.g., anonymously in a random fashion as a shared key, subsequently in conjunction with the EI buyer computing device 926 utilizing a Diffie Hellman approach), selecting the time interval truncation function (e.g., truncate time to within 1 minute), selecting the generator algorithm ID, and selecting the combiner algorithm ID.
The establishing may further include the set up processing 936 of the marketplace server 18 receiving the exchange item data file (i.e., EI information 950) from the issuing server 920 of the data communication system. The receiving may include the EI issuing server 920 utilizing a first level of secure communication regarding the exchange item (e.g., secure link, trusted certificates, first level encryption using a public-private key pair after exchanging public keys). Alternatively, the receiving may include the set up processing 936 receiving the EI information 950 from an initial owner computing device (e.g., the initial owner computing device offers the exchange item for sale via the exchange item marketplace).
Having generated the EI security parameters 1290, the set up processing 936 stores the EI information 950 and the EI security parameters 1290 in the marketplace database 20. Having performed the storing, when the exchange item is purchased by the EI buyer computing device 926, the marketplace server 18 securely provides the one or more security parameters to the user computing device of the data communication system. For example, the set up processing 936 sends the EI information 950 and the EI security parameters 1290 to the EI buyer computing device 926 for storage in the digital wallet 944 for a subsequent EI redemption operation. For instance, the set up processing 936 identifies the EI purchase (e.g., a request from the EI buyer computing device 926 that identifies the static EI serial number), accesses the marketplace database 20 based on the static EI serial number, retrieves the associated EI information 950 and the EI security parameters 1290, and transmits the EI information 950 and the EI security parameters 1290 to the EI buyer computing device 926. Alternatively, the EI security parameters 1290 include parameters to establish the secret key between the set up processing 936 and the EI buyer computing device 926 utilizing an industry approach (e.g., Diffie Hellman approach) such that the secret key is not directly communicated between the marketplace server 18 and the EI buyer computing device 926.
The generating the first dynamically secure exchange item data includes executing, as part of the dynamic securing function, a generator function of a plurality of generator algorithms on the user time value and the one or more security parameters to produce an intermediate resultant (e.g., a number, a value, a code, etc.) and executing an arithmetic function of a plurality of arithmetic functions on the intermediate resultant and the one or more aspects of the copy of the exchange item data file to produce the first dynamically secure exchange item data. (e.g., any type of arithmetic and/or function — add, subtract, combine, append, aggregate, truncate, etc.). The generating of the first dynamically secure exchange item data is discussed in greater detail with reference to
The generating the first dynamically secure exchange item data may alternatively include executing, as part of the dynamic securing function, a generator function of the plurality of generator algorithms on the user time value (e.g., a local time kept by the EI buyer computing device 926 which may be synchronized with a common time source) and the one or more security parameters to produce an intermediate resultant; executing a first arithmetic function of a plurality of arithmetic functions on the intermediate resultant and a first aspect of the one or more aspects of the copy of the exchange item data file to produce first partial dynamically secure exchange item data; executing a second arithmetic function of the plurality of arithmetic functions on the intermediate resultant and a second aspect of the one or more aspects of the copy of the exchange item data file to produce second partial dynamically secure exchange item data; and executing a third arithmetic function of a plurality of arithmetic functions on the first and second partial dynamically secure exchange item data to produce the first dynamically secure exchange item data.
Having generated the first dynamically secure exchange item data, the EI buyer computing device 926 sends the first dynamically secure exchange item data (e.g., dynamic EI information 1292) to the marketplace server 18. The market place server 18 receives the first dynamically secure exchange item data from the user computing device. For example, when the EI buyer computing device 926 redeems the EI, the use processing 940 receives merchant use information 980 (i.e., redemption transaction information, a merchant ID, a brand ID) and the dynamic EI information 1292 (e.g., may be considered as a secure version of the EI info received from the merchant server 924 via the POS equipment 32), where the EI buyer computing device 926 generates the dynamic EI information 1292 based on the EI information 950 utilizing the EI security parameters 1290, where the EI buyer computing device 926 generates buyer use information 976 (e.g., redemption transaction information: purchase amount, identifier of an item purchased, etc.), and where the merchant server 924 issues the merchant use information 980 to the use processing 940 based on the buyer use information 976 received from the EI buyer computing device 926 via the POS equipment 32 (e.g., received via one or more of magnetic stripe, security chip, QR code, barcode, 3-D barcode, manual entry, etc.).
Having received the first dynamically secure exchange item data, the marketplace server generates second dynamically secure exchange item data using the dynamic securing function having inputs that includes a marketplace time value (e.g., a local time kept by the marketplace server 18 which may be synchronized with the common time source), the one or more security parameters, and one or more aspects of the exchange item data file. The generating of the second dynamically secure exchange item data includes executing, as part of the dynamic securing function, the generator function of the plurality of generator algorithms on the marketplace time value and the one or more security parameters to produce an intermediate resultant and executing the arithmetic function of the plurality of arithmetic functions on the intermediate resultant and the one or more aspects of the exchange item data file to produce the second dynamically secure exchange item data.
As an example of the generating of the second dynamically secure exchange item data, the use processing 940 retrieves the EI information 950 and the EI security parameters 1290 from the marketplace database 20 and generates the second dynamically secure exchange item data based on the retrieved EI information 950 and the EI security parameter 1290. Having generated the second dynamically secure exchange item data, the marketplace server compares the first dynamically secure exchange item data with the second dynamically secure exchange item data (e.g., compares a received dynamic identifier to a locally generated dynamic identifier of the exchange item). When the first dynamically secure exchange item data substantially matches the second dynamically secure exchange item data, the marketplace server authorizes the use of the exchange item by the user computing device. For example, the use processing 940 indicates that the use of the exchange item by the user computing device is authorized when the received dynamic ID substantially matches the locally generated dynamic ID.
The use processing 940 may further verify the redemption of the EI. For example, the use processing 940 retrieves the EI serial number from the EI information 950 (i.e., from the marketplace database 20), issues a supplemental use verification request 1294 (i.e., EI info, redemption transaction info) to the EI issuing server 920 that includes the EI information 950 and the information of the redemption (e.g., merchant use information 980), where the EI issuing server 920 exchanges trust information 954 with the EI trusted module 922, and interprets a received supplemental use verification response 1296 (i.e., EI info, redemption transaction info, approval status: yes/no) to produce a further indication of authorization (i.e., indicate favorable authorization when the response is favorable, such as when the EI trusted module 922 and/or the EI issuing server 920 verify that a remaining balance of the exchange item (e.g., based on the static portion of the EI serial number) is sufficient to provide payment for a purchase associated with the redemption of the exchange item).
In an example of operation of the generating of the dynamic EI information, the dynamic number generator 1298 applies one or more deterministic functions (e.g., a hash based message authentication code (HMAC), a sponge function, a hashing function, a signature function, a cyclic redundancy check (CRC), a checksum function, and a mask generating function (MGF) in accordance with the generator algorithm ID 1308 (e.g., to select which deterministic function(s)) to the time 1302 (e.g., real-time) in accordance with a time interval increment 1306 (i.e., a time truncation interval of 30 seconds) utilizing a secret key 1304 to produce a dynamic EI number portion 1314. For example, the dynamic number generator 1298 selects the HMAC based on the generator algorithm ID 1308, represents the time 1302 within a 30 second interval (i.e., xx:xx:00 or xx:xx:30) when the time interval increment 1306 indicates 30 second intervals, and applies the HMAC function to the represented time utilizing the secret key 1304 to produce an HMAC function output as the dynamic EI number portion 1314.
With the dynamic EI number portion 1314 produced, the combiner combines the dynamic EI and a portion of the EI information 950 (i.e., a static EI number portion 1312 of the EI information 950 in accordance with a combiner algorithm ID 1310 (i.e., arithmetic function) of the EI security parameters 1290) to produce the dynamic EI information 1292. As such, the dynamic EI information produces a secure version of the EI serial number, where a portion of the secure version may include static bits of the static EI number portion 1312 and dynamic bits of the dynamic EI number portion 1314 in accordance with the combiner algorithm ID 1310. For instance, the combiner algorithm ID indicates which bits are to be utilized for static bits and which bits are to be utilized for dynamic bits. Alternatively, or in addition to, the combiner 1300 may utilize one or more other variables to produce the static and dynamic bits, where the one or more other variables includes one or more of the time 1302, the secret key 1304, the time interval increment 1306, and the generator algorithm ID 1308. The combiner 1300 may replace static bits of the EI serial number with dynamic bits including replacement of most significant bits, middle bits, we significant bits, random bits, a combination, a personal identification (PIN) portion, etc. For example, the combiner 1300 utilizes most significant bits associated with 10 most significant numbers of the EI serial number and least significant bits of the dynamic EI number portion 1314 to generate 6 least significant numbers of the EI serial number to produce a 16-digit secure version of the EI serial number as the first or second dynamically secure exchange item data.
The method continues at step 1322 where the marketplace server securely provides the one or more security parameters to the user computing device of the data communication system. For example, the marketplace server provides the one or more security parameters to the user computing device when the user computing device purchases the exchange item.
When the user computing device desires to use the exchange item, the method continues at step 1324 where the user computing device generates first dynamically secure exchange item data using a dynamic securing function having inputs that include a user time value, the one or more security parameters, and one or more aspects of a copy of the exchange item data file in the possession of the user computing device (e.g., when the one or more aspects of the copy of the exchange item data file are held by the user computing device). The generating the first dynamically secure exchange item data includes executing, as part of the dynamic securing function, a generator function of a plurality of generator algorithms on the user time value and the one or more security parameters to produce an intermediate resultant. For example, the user computing device performs a hash based message authentication code on the user time value in accordance with a time truncation interval (i.e., 1 minute intervals) utilizing a secret key of the one or more security parameters to produce the intermediate resultant. The generating further includes executing an arithmetic function of a plurality of arithmetic functions on the intermediate resultant and the one or more aspects of the copy of the exchange item data file to produce the first dynamically secure exchange item data. For example, the user computing device replaces a most significant 10 bits of a static exchange item identifier of the one or more aspects of the copy of the exchange item data file with a most significant 10 bits of the intermediate resultant to produce the first dynamically secure exchange item data.
The generating the first dynamically secure exchange item data may alternatively include executing, as part of the dynamic securing function, a generator function of the plurality of generator algorithms on the user time value and the one or more security parameters to produce an intermediate resultant; executing a first arithmetic function of the plurality of arithmetic functions on the intermediate resultant and a first aspect of the one or more aspects of the copy of the exchange item data file to produce first partial dynamically secure exchange item data; executing a second arithmetic function of the plurality of arithmetic functions on the intermediate resultant and a second aspect of the one or more aspects of the copy of the exchange item data file to produce second partial dynamically secure exchange item data; and executing a third arithmetic function of the plurality of arithmetic functions on the first and second partial dynamically secure exchange item data to produce the first dynamically secure exchange item data.
For instance, the user computing device performs the hash based message authentication code function on the user time value utilizing the secret key of the one or more security parameters to produce the intermediate resultant; replaces a most significant 8 bits of the static exchange item serial number with a most significant 8 bits of the intermediate resultant to produce the first partially dynamically secure exchange item data; replaces a least significant 3 bits of a remaining balance indicator of the one or more aspects of the copy of the exchange item data file to produce the second partial dynamically secure exchange item data and combines the first and second partial dynamically secure exchange item data to produce the first dynamically secure exchange item data, where the first dynamically secure exchange item data includes 8 bits of the static exchange item serial number, 3 bits of the static exchange item serial number, and 3 bits of the remaining balance.

When the computing device initiates redemption of the marketplace exchange item, the method continues at step 1596 where the processing module exchanges purchase information with the computing device to fill facilitate purchase of one or more of the exchange items for purchase. The exchanging includes one or more of receiving an identifier for an exchange item to purchase when redeeming the marketplace exchange item associated with the computing device and sending a confirmation of the purchase of the exchange item to the computing device.
In an example of operation, the marketplace server 18 determines to generate a dynamic ID 1604 for an exchange item having EI information. The EI information includes the exchange item value, type, issuance date, expiration date, use parameters, a static ID 1602, etc. The static ID 1602 includes an EI serial number and an EI issuer ID, where the EI serial number is issued at creation of the exchange item. For example, the exchange item currently owned by computing device 1598 (e.g., a first owner AA) has an EI serial number 001 and an EI issuer IDA_1 as its static ID 1602.
The marketplace server 18 may determine to generate a dynamic ID for an exchange item for several reasons. For example, the marketplace server 18 determines to generate a dynamic ID for an exchange item if the computing device 1598 sends the marketplace server 18 a request to create the dynamic ID and/or the marketplace server 18 identifies that the computing device 1598 has a standard procedure to generate a dynamic ID for exchange items. Alternatively, or additionally, the marketplace server 18 determines to generate a dynamic ID for an exchange item when the marketplace server 18 identifies a standard procedure of generating dynamic IDs for exchanges items from a particular processor server, a particular brand server, and/or a particular distributor server. As other examples, the marketplace determines to generate a dynamic ID by one or more of interpreting an exchange item rule, waiting a predetermined time period, and determining a security issue. For example, the marketplace server 18 determines to generate a dynamic ID to protect the exchange item from corruption when fraud is detected within the network.
The marketplace server 18 generates the dynamic ID 1604 by one or more of generating a random alphanumeric value, applying a deterministic function on at least part of the exchange item information, applying an encrypting function on at least part of the exchange item information, applying an encoding function on at least part of the exchange item information, and applying at least one of a mathematical function and a logical function on at least part of the exchange item information. A secure chain of custody for the exchange item (which includes a secure data block featuring the EI information) is updated to include a new secure data block representative of the generation of the dynamic ID 1604 and to include an indication that use of the static ID 1602 has been suspended in favor of use of the dynamic ID 1604 within the marketplace computing network. Updating the secure chain of custody will be discussed in greater detail with reference to
The marketplace server 18 updates the exchange item within the computing device's 1598 digital wallet 1600 to include the dynamic ID 1604. For example, to update the digital wallet 1600, the marketplace server 18 downloads the dynamic ID 1604 to the digital wallet 1600. The owner table is updated to include a column for the dynamic ID 1604 generated for the exchange item (e.g., dynamic ID 100). The marketplace server 18 also sends a notification 1606 that use of the static ID 1602 is suspended in favor of the dynamic ID 1604. Alternatively, the marketplace server 18 may send a notification 1606 that the static ID 1602 is to be replaced with the dynamic ID 1604. The marketplace server 18 updates the secure chain of custody to include a new secure data block representative of updating the digital wallet 1600. The marketplace server 18 also shares security parameters 1608 with the computing device 1598 to allow the computing device 1598 to access sections of the secure chain of custody relevant to the generation of the dynamic ID and the updating of the digital wallet 1600.
The marketplace server 18 further updates the EI database 934 to include the dynamic ID 1604 for the exchange item, the indication that the use of the static ID has been suspended in favor of use of the dynamic ID, and a copy of the static ID. As shown, a dynamic ID of 100 is generated for the exchange item owned by the computing device 1598 and added into the EI database 934. An additional dynamic ID column demonstrates that an exchange item may be assigned more than one dynamic ID associated with the same owner. For example, various dynamic IDs may be used to set boundaries for different types of purchases.
The marketplace server 18 detects use of the exchange item 1610 by the computing device 1598 (e.g., a purchase transaction or a sale of the EI). When the detected use of the exchange item 1610 is in accordance with the dynamic ID, the marketplace server 18 can trust the computing device and processes the use of the exchange item. For example, if the detected use is a purchase transaction using the exchange item, the marketplace server 18 facilitates completion of the purchase transaction, facilitates payment distribution from the computing device 1598 to a merchant of the marketplace computing network, and updates the exchange item information to reflect the completed purchase transaction and the payment distribution. When the detected use is a sale of the exchange item, the marketplace server 18 facilitates completion of the sale of the exchange item, facilitates payment distribution from a purchaser of the exchange item to the computing device 1598, and updates the exchange item information to reflect the completed sale and the payment distribution.
When the detected use of the exchange item 1610 is in accordance with the static ID 1602, the marketplace server 18 denies the requested use of the exchange item 1606.
In reference to
When the marketplace server updates the computing device's digital wallet, the marketplace server is the transactor and the computing device is the transactee. The secure chain of custody 1616 is updated by adding the secure data block x+2 which includes a transaction section 1614 populated with information regarding updating the digital wallet (e.g., dynamic ID is downloaded to the digital wallet and a notification that use of the static ID is suspended in favor of the dynamic ID (or replaced with the dynamic ID) is sent).
At some later point in time, the marketplace server detects use of the exchange item by the computing device (e.g., a sale of the EI or a purchase transaction). When the detected use is in accordance with the dynamic ID, the use is processed and this information is included in the transaction section of secure data block x+3, which is added to the secure chain of custody 1616. Alternatively, when the detected use is in accordance with the static ID, the use is denied and this information is included in the transaction section of secure data block x+3, which is added to the secure chain of custody 1616.
The marketplace server may determine to generate a dynamic ID for an exchange item for several reasons. For example, the marketplace server determines to generate a dynamic ID for an exchange item if the computing device sends the marketplace server a request to create the dynamic ID and/or the marketplace server identifies that the computing device has a standard procedure to generate a dynamic ID. Alternatively, or additionally, the marketplace server determines to generate a dynamic ID for an exchange item when the marketplace server identifies a standard procedure of generating dynamic IDs for exchanges items from a particular processor server, a particular brand server, and/or a particular distributor server. As other examples, the marketplace determines to generate a dynamic ID by one or more of interpreting an exchange item rule, waiting a predetermined time period, and determining a security issue. For example, the marketplace server determines to generate a dynamic ID to protect the exchange item from corruption when fraud is detected.
The method continues with step 1620 where the marketplace server generates the dynamic ID by one or more of generating a random alphanumeric value, applying a deterministic function on at least part of the exchange item information, applying an encrypting function on at least part of the exchange item information, applying an encoding function on at least part of the exchange item information, and applying at least one of a mathematical function and a logical function on at least part of the exchange item information.
The method continues with step 1622 where a secure chain of custody for the exchange item (which includes a secure data block featuring the EI information) is updated to include a new secure data block representative of the generation of the dynamic ID and to include an indication that use of the static ID has been suspended in favor of use of the dynamic ID within the marketplace computing network.
The method continues with step 1624 where the marketplace server 18 updates the exchange item within the computing device's digital wallet to include the dynamic ID. For example, to update the digital wallet, the marketplace server downloads the dynamic ID to the digital wallet. The marketplace server also sends a notification that use of the static ID is suspended in favor of the dynamic ID. Alternatively, the marketplace server may send a notification that the static ID is to be replaced with the dynamic ID. The marketplace server updates the secure chain of custody to include a new secure data block representative of updating the digital wallet. The marketplace server also shares security parameters with the computing device to allow the computing device to access sections of the secure chain of custody relevant to the generation of the dynamic ID and the updating of the digital wallet. The marketplace server further updates the EI database to include the dynamic ID for the exchange item, the indication that the use of the static ID has been suspended in favor of use of the dynamic ID, and a copy of the static ID. An exchange item may be assigned more than one dynamic ID associated with the same owner. For example, various dynamic IDs may be assigned to set boundaries for different types of purchases.
The method continues with step 1626 where the marketplace server detects use of the exchange item by the computing device (e.g., a purchase transaction or a sale of the EI). The method continues with step 1628 where, when the detected use of the exchange item is in accordance with the dynamic ID, the marketplace server processes the use of the exchange item. For example, if the detected use is a purchase transaction using the exchange item, the marketplace server facilitates completion of the purchase transaction, facilitates payment distribution from the computing device to a merchant of the marketplace computing network, and updates the exchange item information to reflect the completed purchase transaction and the payment distribution. When the detected use is a sale of the exchange item, the marketplace server facilitates completion of the sale of the exchange item, facilitates payment distribution from a purchaser of the exchange item to the computing device, and updates the exchange item information to reflect the completed sale and the payment distribution. However, when the detected use of the exchange item is in accordance with the static ID, the marketplace server denies the requested use of the exchange item.

- when the use request includes the dynamic identifier, facilitating executing of the use request regarding the first exchange item.
5. The method of claim 4 further comprises:
- when the use request does not include the dynamic identifier, denying the use request regarding the first exchange item.
6. The method of claim 1 further comprises:
- determining to convert a second exchange item of the plurality of exchange items from a second static exchange item into a second dynamic exchange item, wherein the converting includes: obtaining second static bits of a second static identifier associated with the second exchange item; generating second dynamic bits based on second security parameters associated with the second exchange item; performing a second dynamic securing function to combine at least a portion of the second static bits with at least a portion of the second dynamic bits to produce a second dynamic identifier; and updating, in the marketplace database, a second record associated with the second exchange item to include the second dynamic identifier.
7. The method of claim 1, wherein the determining to convert the first exchange item is based on receiving a conversion request.
8. The method of claim 1, wherein the determining to convert the first exchange item is based on a predetermination.
9. The method of claim 1, wherein the determining to convert the first exchange item is based on interpreting an exchange item rule associated with the first exchange item.
10. The method of claim 1, wherein the determining to convert the first exchange item is based on determining a security issue.
11. The method of claim 1, wherein the determining to convert the first exchange item is based on determining a time period has lapsed.
12. The method of claim 1 further comprises:
- detecting use of the first exchange item; and
- when the detected use is in accordance with the dynamic identifier, processing the use of the first exchange item.
13. The method of claim 1, wherein the static identifier comprises:
- an exchange item serial number and an exchange item issuer identifier, wherein the exchange item serial number is issued at creation of the exchange item.
14. The method of claim 1, wherein the determining to convert the first exchange item is based on one or more of:
- receiving a conversion request from an owner computing device that is associated with the first exchange item; and
- identifying a standard procedure of converting the first exchange item based on at least one of:
- a particular processor server, a particular brand server, and a particular distributor server.
15. The method of claim 1 further comprises:
- updating a secure chain of custody of the first exchange item to include the dynamic identifier and to include an indication that use of the static identifier has been suspended in favor of use of the dynamic identifier within the marketplace computing network.
16. The method of claim 15, wherein the updating the secure chain of custody of the first exchange item comprises:
- creating a secure data block regarding the dynamic identifier, wherein the secure data block is included in the secure chain of custody of the first exchange item, wherein the secure data block incudes a header section and a transaction section, and wherein the transaction section includes information regarding the dynamic identifier and the indication that use of the static identifier has been suspended in favor of use of the dynamic identifier.
17. The method of claim 1, wherein the producing the dynamic identifier further comprises:
- determining, based on a combiner function, particular ones of the static bits to be replaced by the at least a portion of the dynamic bits.
18. The method of claim 1, wherein the dynamic bits are generated based on applying a deterministic function on at least part of exchange item information associated with the first exchange item.
19. The method of claim 1, wherein the dynamic bits are generated based on applying an encoding function on at least part of exchange item information associated with the first exchange item.
20. The method of claim 1, wherein the dynamic bits are generated based on applying a encryption function on at least part of exchange item information associated with the first exchange item.
