摘要
A method and system for decentralized biometric signing of a digital contract. A private key is encrypted using biometric data captured, from a user, on a mobile device. The encrypted private key, a public key associated with the private key, and a digital identity pertaining to the user and the captured biometric data are stored on the mobile device. A digital hash of the digital contract is generated. Using the captured biometric data, the user is authenticated and the encrypted private key is decrypted. The digital hash is signed with the decrypted private key. The signed digital hash of the digital contract, the digital contract prior to being hashed, the identifier, the certifier of the identifier, the public key, a certification of the public key by a third party, and a record of a successful authentication of the user using the biometric data are stored in a blockchain.
