Abstract

It is proposed to combine the advantages of PIN-based protection systems and biometry-based protection systems and avoid the disadvantages of the respective systems by generating the PIN biometrically uniquely. For this purpose it is provided that only characteristic data that are uniquely reproducible are derived from the determined biometric raw data. On the basis of these uniquely reproducible characteristic data a key record is then generated that either constitutes the PIN code or is used to generate the PIN code. The PIN code is thus always reproducible uniquely on the basis of the biometric data. The user need no longer remember the PIN code, and the PIN code cannot be passed on to third parties.
