TRANSACTION SIGNING UTILIZING ASYMMETRIC CRYPTOGRAPHY

摘要

Embodiments relate to systems, apparatuses, and methods for performing transaction signing utilizing asymmetric cryptography and a private ledger. A transaction data is signed by a user device using a private key, and may be utilized in an authorization request message without including a real credential of the user. A transaction verification and accounting module (TVAM) can verify the signed transaction data and can continue processing the transaction.

1. A method comprising:
receiving, at a server computer, an authorization request message for a transaction involving a user and a recipient, wherein the authorization request message includes a public key of the user and signed transaction data, wherein the signed transaction data was signed using a private key of the user; determining, by the server computer, that the public key of the user matches a stored public key associated with an entry of the user; determining, by the server computer using the public key, that the signed transaction data was signed using the private key of the user; and sending, by the server computer, an authorization response message indicating that the transaction is authorized.
