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.
