Capacity and Examples of Template-Protecting Biometric Authentication Systems

Abstract. In this paper, we formulate the requirements for privacy protecting biometric authentication systems. The secrecy capacity Cs is investigated for the discrete and the continuous case. We present, furthermore, a general algorithm that meets the requirements and achieves Cs as well as Cid (the identification capacity). Finally, we present some practical constructions of the general algorithm and analyze their properties.
