A Novel Biometric Authentication Scheme with Privacy Preserving

In this paper, a novel biometric authentication scheme is proposed, which combines zero-knowledge proof, Σ - protocols and bit commitment scheme. The remote server compares biometric template using committed values, this can keep privacy of user´s biometrics. To the best knowledge of us, this is the first scheme which uses Σ - protocols as a basic tool to implement biometric authentication. Compared with the previous schemes, this scheme has advantages as higher security, lower computation complexity and privacy keeping of biometric template.
