A biometric identification method includes the steps of acquiring biometric data, analysing the data to produce a current signature, and comparing the current signature with a reference signature. To this process is added the further step of verifying the origin of the current signature, by determining whether the signature is actually the result of the analysis of the biometric data obtained during the acquisition phase. The verification and comparison steps are preformed in a portable electronic device, such as a smart card.

Biometric identification method, portable electronic device and electronic device acquiring biometric data therefor

A method for detecting portable objects from a network of N antennae controlled by a centralized management unit. Signals are simultaneously emitted by the management unit to all antennae. Resulting response signals from antennae that have detected a portable object are received by the management unit. Each object thus detected is successively selected from these signals according to a pre-established sequence. The invention applies in particular to access control.
