AUTHENTICATION NETWORK FOR TRANSACTION DATA

Abstract:

Various embodiments herein each include at least one of systems, methods, software, and data structures of an authentication network for transaction data. One method embodiment includes electronically receiving an account identifier associated with a purchase transaction and, for each item in the purchase transaction, an item identifier and price data. The method proceeds by generating a data structure in memory for each item included in the purchase transaction. The data structure of each item includes an item identifier and respective price data. Each data structure is then signed in memory with a private key of a private/public key-pair of a merchant of the purchase transaction. The method further proceeds by transmitting each data structure generated for the purchase transaction to a location associated with the account identifier.
