Abstract: A method includes detecting, by a marketplace server of a computing network, fraudulent acquisition of an exchange item by a first computing device of the computing network. The exchange item has a first dynamic identifier (ID) that was created for the first computing device, where the first computing device is a first owner of the exchange item, exchange item information is associated with the exchange item, and the exchange item information includes a static ID of the exchange item. The method further includes deactivating, by the marketplace server, the first dynamic ID in response to the detecting fraudulent acquisition. The method further includes, after deactivating the first dynamic ID, detecting, by the marketplace server, requested use of the exchange item by the first computing device, denying, by the marketplace server, the requested use of the exchange item, and reclaiming, by the marketplace server, ownership of the exchange item.

Abstract: A method begins with storing, by an enterprise storage, an exchange item database, an agreements database, and a rules database. The method continues with an enterprise server initially validating exchange items and creating 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 method continues with the enterprise server securely transferring 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 and securely applying the selected exchange item to a closed loop digital transaction between two computing entities in accordance with an agreement of the agreements database. The method continues with the enterprise server securely modifying the data of the selected exchange item in accordance with an applicable set of rules from the rules database.

Abstract: A method includes receiving, by a marketplace server, a request to use a digital exchange item from a computing device. The method further includes obtaining secure custody of a digital chain of custody of the digital exchange item where the digital exchange item has been updated in regards to the request. The method further includes verifying exchange item information and exchange item use information and updating the digital chain of custody of the digital exchange item accordingly. When the exchange item information and exchange item use information is verified, the method further includes verifying merchant information regarding the requested use of the digital exchange item and updating the digital chain of custody of the digital exchange item accordingly. When the merchant information is verified, the method further includes executing the use of the digital exchange item and updating the digital chain of custody of the digital exchange item accordingly.

Abstract: A method includes receiving, by a warehouse server, flash sale data file from a retail-type server. The method further includes storing, by the warehouse server, the flash sale data file in a database that functions as a virtual warehouse of flash sales. The method further includes interpreting, by the warehouse server, the information of the flash sale data file to determine flash sale parameters. The method further includes determining, by the warehouse server, whether a computing device has customer-device data that corresponds to the flash sale parameters. The method further includes, when the computing device has the customer-device data that corresponds to the flash sale parameters, generating, by the warehouse server, a customer specific coupon regarding the flash sale. The method further includes transmitting, by the warehouse server, the customer specific coupon to the computing device.
