The first processing station is arranged for storing data corresponding to a signature and to caller identification information for respective users. The second processing station or stations each include a speaker verification unit and a processor. The speaker verification unit is adapted for receiving, via the public telephone system, a voice and/or touch-tone signal representing a signature of a possible user, and for digitally signal processing the signal representing the signature. The processor is connected to the speaker verification unit and is adapted for connection to the first station via a telephone line between the first and second stations, programmed to receive caller identification information for the possible user and to receive a digitally processed signature signal for the possible user from the speaker verification unit, and programmed to communicate with the first station via the telephone line in order to test the signature of the possible user against the valid signature of the user corresponding to the received caller identification information.Other References
