Abstract
A method and system for decentralized biometric signing of a digital contract. A digital identity including a private key is created. The private key was encrypted on a mobile device via use of captured biometric data. A digital hash of the digital contract is generated. A user using biometric data is authenticated. Usage of the biometric data is authorized. Responsive to the usage of the biometric data being authorized, the encrypted private key is decrypted. The digital hash is signed with the decrypted private key. The signed digital hash is stored in a blockchain.
