Cryptographic protection of biometric templates: Chance, challenges and applications

: In this contribution a survey is presented about the possibilities and difficulties of a cryptographic protection of biometric information for the purpose of authentication. The crucial role of sufficient information content of biometric templates will be presented. It will be shown how to use this approach of a cryptographic protection of biometric templates in connection with biometric databases. Finally, a proposal is given, how to combine it with centralised PIN verification procedures in online banking scenarios as a new application scenario.
