Title:
Capacity and Examples of Template Protecting Biometric Authentication Systems

Authors: P. Tuyls, 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.
