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.enText/Conference Paper1617-5468
