Abstract: A method for execution by one or more servers of an exchange item marketplace network includes receiving, from a computing device, an acquisition request regarding an exchange item of a plurality of exchange items of the exchange item marketplace network. The method further includes obtaining user information associated with the computing device and device information associated with the computing device. The method further includes selecting a fraud determination approach of a plurality of fraud determination approaches based on the user information and the device information, where the selected fraud determination approach includes a traversing nodes of a fraud decision tree. The method further includes performing a decision tree analysis function on the fraud decision tree to produce a predicted fraud level for the acquisition request.

Abstract: A method includes initiating, by a first computing device, ownership acquisition of a good from a second computing device using a digital exchange item. The method further includes determining, by the second or a third computing device, whether a first warranty is applicable to the good. When the first warranty is applicable, the method further includes obtaining, by the second and/or the third computing device, a representation of the first warranty. The method further includes executing, by the second and/or the third computing device, the ownership acquisition of the good by the first computing device using the digital exchange item, wherein the executing includes updating a digital chain of custody of the digital exchange item. The method further includes updating, by the second and/or the third computing device, the digital chain of custody to include affiliation of the first warranty to the good and to the first computing device's user.

Abstract: A method includes establishing an agreement between a first issuing server and a second issuing server regarding first exchange items to have an extended use corresponding to a second type of use. The method further includes storing, by a server, the agreement. The method further includes receiving, by the server, a request for use of a first exchange item from a merchant server regarding a transaction by a user computing device for a particular item. The method further includes determining, by the server, whether the merchant server is affiliated with the first or second issuing server. The method further includes, when the merchant server is affiliated with the second issuing server, interpreting, by the server, the agreement to determine extended use parameters. The method further includes processing, by the server and in accordance with the extended use parameters, use of the first exchange item for the particular item.

Abstract: A method begins with a server recording conditions for an exchange item. The method continues with the server determining whether a corresponding condition of the exchange item is compliant with one or more rules of an applicable set of rules. When the corresponding condition of the exchange item is compliant with the one or more rules, the method continues with the server establishing a secure communication with a computing device affiliated with a current owner to take control of the exchange item. While having control over the exchange item, the server securely modifies a quantifiable value of the exchange item based on the one or more rules to produce a modified exchange item and prevents the computing device or another computing device from accessing the exchange item. The method continues with the server releasing control of the modified exchange item to the computing device affiliated with the current owner.

Abstract: A method begins with detecting an error regarding one or more parameters associated with a blockchain transaction between a first entity and a second entity to be included in a primary blockchain in accordance with a primary blockchain protocol. The method continues with facilitating generation of a secondary blockchain between the first entity and a third entity in accordance with a secondary blockchain protocol, where the secondary blockchain includes blockchain data corresponding to the one or more parameters to resolve the error. The method continues by validating the secondary blockchain in accordance with the secondary blockchain protocol. When the secondary blockchain is valid, the method continues with including the secondary blockchain within the blockchain transaction to produce an updated blockchain transaction, adding the updated blockchain transaction to a next block of the primary blockchain, and linking the next block to the primary blockchain in accordance with the primary blockchain protocol.

Abstract: A method includes a marketplace server establishing one or more security parameters for an exchange item and securely providing the one or more security parameters to a user computing device of the data communication system. When the user computing device desires to use the exchange item, the method further includes generating, by the user computing device, first dynamically secure exchange item data. The method further includes the marketplace server receiving the first dynamically secure exchange item data from the user computing device, generating second dynamically secure exchange item data, and comparing the first dynamically secure exchange item data with the second dynamically secure exchange item data. When the first dynamically secure exchange item data substantially matches the second dynamically secure exchange item data, the method further includes authorizing, by the marketplace server, the use of the exchange item by the user computing device.

Abstract: A method begins with a server in a data communication system identifying an instance for a user computing device associated with an exchange item to utilize the exchange item for acquisition of a particular item, where the particular item has an acquisition value. For the instance, the method continues with the server determining whether a quantifiable value of the exchange item compares favorably to the acquisition value, where a set of exchange item rules includes rules established by an issuing server regarding use of the exchange item with respect to the particular item. When the quantifiable value of the exchange item does not compare favorably to the acquisition value, the method continues with the server determining an alternative exchange item utilization protocol to facilitate the acquisition of the particular item and when requested, executing the alternative exchange item utilization protocol to facilitate the acquisition of the particular item.

Abstract: A method begins with a server in a data communication system establishing an initial validity of an 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 method continues with the server executing a secure custody protocol to establish that a first computing device has secure custody of the exchange item and to maintain validity of the exchange item. The method continues with the server transferring the secure custody of the exchange item from the first computing device to the server or to a second computing device. When the exchange item is in the secure custody of the server the method continues with the server modifying the data of the exchange item to produce a modified exchange item and transferring secure custody of the modified exchange item to the first computing device.
