Abstract

This paper proposes a novel secure biometric authentication scheme that hides the biometric features and the distance between the enrolled and authenticated biometric features, and prevent impersonation. To confirm that the proposed scheme has such properties, we formally model secure biometric authentication schemes by generalizing the related and proposed schemes. As far as we know, the proposed scheme is the first one that has been proved to satisfy all the properties. In particular, the proposed scheme achieves security under the decisional Diffie-Hellman assumption.
