International Workshop on Biometric Authentication, 2004•SpringerIn this paper, we formulate precisely the requirements for privacy protecting biometric
authentication systems. The secrecy capacity C s is investigated for the discrete and the
continuous case. We present, furthermore, a general algorithm that meets the requirements
and achieves C s as well as C id (the identification capacity). Finally, we present some
practical constructions of the general algorithm and analyze their properties.

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.
