Abstract

The invention provides a blockchain-based payment system and a blockchain-based payment method and relates to the technical field of payment. The blockchain-based payment system comprises a payee payment terminal, a face recognition server, a blockchain node and a cloud storage system, wherein the payee payment terminal executes attribute encryption on traction information and face data transmitted by face recognition equipment and transmits a first data ciphertext to the face recognition server through a gateway; the face recognition server performs decryption to acquire face data and a payerwallet address as well as acquires a private key corresponding to the payer wallet address and preset face data from a cloud storage system; and if the face data and the preset face data meet the preset recognition condition, the private key is invoked to sign the transaction, the transaction information after attribute encryption is broadcast in the system, the blockchain node decrypts the transaction information and performs verification, and the transaction information is recorded in the blockchain if the verification is passed. The blockchain-based payment system introduces face swiping payment, encrypts the transaction information and can meet diversified payment requirement and safety requirement.

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. Background technique [0002] At present, when a user uses a payment system based on blockchain technology in the prior art for transaction payment, the user usually needs to use a hardware device (such as a mobile phone) that stores its own private key to complete the digital signature of the transaction. The payment method is single and cannot Meet the diverse payment needs of users. Moreover, most of the existing payment technologies lack the protection of transaction information, which easily leaks the user's privacy and brings inconvenience to the user. Contents of the invention [0003] In view of this, the purpose of the present invention is to provide a blockchain-based payment system and method to alleviate the need for the user to complete the digital signature of the transaction with the help of a har...
