The invention relates to a personal identification method based on requirements. An authentication checking system (1) thereby receives an authentication requirement (7) from a service provision system (5) and said requirement is analyzed and the required authentication level (9) is determined from the same. After activating (21) a detecting means (3) of a detecting device (2), a personal identifier is detected (22) and compared (23) to a corresponding reference feature (14) stored in a memory unit (15, 16). If the comparison matches, a release signal (17) is provided to the service provision system (5); if the match is incorrect (25) a further detecting means (3) of the detecting device (2) is activated and the corresponding process steps are repeated.
