Abstract

The present invention provides a blockchain-based payment system and method, which relate to the technical field of payment and include: a payee payment terminal, a face recognition server, a blockchain node and a cloud storage system, and the payee payment terminal stores transaction information Perform attribute encryption on the face data sent by the face recognition device, send the first data ciphertext to the face recognition server through the gateway, and the face recognition server decrypts the face data and the payer’s wallet address, and obtains them from the cloud storage system The private key corresponding to the payer’s wallet address and the preset face data, if the face data and the preset face data meet the preset identification conditions, the private key is called to sign the transaction, and the transaction information after attribute encryption is broadcast to the system , the blockchain node decrypts the transaction information and verifies it, and if it passes, the transaction information is recorded in the blockchain. The blockchain-based payment system of the present invention introduces facial recognition payment and encrypts transaction information, which can meet diversified payment requirements and security requirements.

Description

technical field [0001] The present invention relates to the technical field of transaction payment, in particular to a blockchain-based payment system and method.
