Biometric authentication establishes the identity of an individual based on biometric templates (i.e. fingerprints, retina scans etc.). Although biometric authentication has important advantages and many applications, it also raises serious security and privacy concerns. In this parer, we investigate a privacy-preserving biometric authentication protocol that has been proposed by Bringer et al. and adopts a distributed architecture (i.e. multiple entities are involved in the authentication process). We present an attack algorithm that can be employed to mount a number of attacks on the protocol under investigation and propose an improved version of the Bringer et al. protocol that combats the presented attacks.
