Capacity and Examples of Template-Protecting Biometric Authentication Systems

چکیده
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.

متن کاملSmart Cards: Remote Authentication using Biometrics
This paper presents an architecture for a secure and reliable remote authentication system, based on local biometric signature validation. Biometric systems are a more secure and reliable authentication mechanism than those that use PIN and passwords. This authentication is based on something that is unique to each person and cannot be lost or borrowed, ensuring the presence of the specific per...
