Abstract
In a method for authenticating persons, video information of certain body features associated with a user or a user group is recorded in a point of presence (POP). Such recorded video information is processed to derive biometric keys, which are stored in tables of a biometric server and in a SIM-card of the user. Each biometric key in the tables is assigned to a respective user. When the user inserts the SIM-card containing a personal biometric key into a communication terminal device, video information describing current body feature of the user is recorded via a video sensor that is not in the communication terminal device. The recorded current video information is then transmitted from the video sensor to the communication terminal device. To authenticate the user, the recorded current video information is processed to derive current biometric keys and compared with pre-stored biometric keys. The authenticity of the user is ensured if the comparison yield a positive result.
