Abstract: A terminal (40) and a transponder (10) contain a corresponding oscillating circuit (Li,Ci,24,L2,C2). An AM transmission of a signal sends a boundary-mark toward the transponder a signal (Rx) undergo a phase demodulation in the boundary-mark. The depth o modulation (tm) of the amplitude is lower than 100%. An Independent claim is included for: (a) a terminal for performing a claimed method (b) a transponder

Abstract: The invention relates to a method of supplying a private quantity (s) in an integrated circuit involved in an authentication procedure by means of an external device that takes said private quantity into account. In order to verify the integrity of said memory element, the private quantity is a function of a signature (SIGN) of at least one memory element (4, 10, 11, 12) associated with the integrated circuit.

Abstract: A portable means of identification (10) has a fingerprint captor (1) which is associated with an extraction and digitization unit (12). An identifier (16) which is drawn from a system of physical parameters (17) such as a time constant relating to the captor is combined with the fingerprint data and scrambled (15). The result is compared (13) with a reference model (14) to give an identification An Independent claim is also included for: A portable identifying equipment which uses the captor physical parameter identifier
