Abstract
A biometric data processing method implemented by a proof entity and a verification entity that are connected. The proof entity has a candidate biometric data, a reference biometric data, cryptographic footprints of the reference biometric data, and the candidate biometric data. The verification entity has a set of cryptographic footprints of reference biometric data of authorized users. The method includes generating the proof entity of a zero-knowledge proof of the fact that the candidate biometric data and the reference biometric data match. Transmitting to the verification entity the zero-knowledge proof of the cryptographic footprints of the candidate biometric data and the reference biometric data. Verifying that the zero-knowledge proof is valid, and the received cryptographic footprint of the reference biometric data belongs to the set of cryptographic footprints of reference biometric data in the possession of the verification entity.
