A Privacy-preserving Biometric Authentication Protocol Revisited

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