Capacity and Examples of Template Protecting Biometric Authentication Systems

P. Tuyls and J. Goseling

Abstract

In this paper, we formulate precisely 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.
