Abstract: The invention is a method of managing communication between a host device and a secure element comprising two virtual profiles. The method comprises the steps of: running simultaneously both virtual profiles in the secure element, generating an incoming data from the host device by multiplexing a first command targeting one virtual profile and another command targeting the other virtual profile and sending the incoming data to the secure element, demultiplexing both commands at the secure element side and sending each command to the targeted virtual profile, getting response messages generated by both virtual profiles by executing said commands, generating an outgoing data by multiplexing the response messages and sending this outgoing data to the host device, and demultiplexing the response messages at the host device side.

Abstract: 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.

Abstract: 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.

Abstract: The invention concerns a biometric identification method comprising a step which consists in acquiring biometric data, a step which consists in analysing said data producing a current signature and a step which consists in comparing said current signature with a reference signature. The invention is characterised in that the method further comprises a step which consists in verifying the origin of the current signature, determining whether the signature is actually the result of the analysis of the biometric data obtained during the acquisition phase. The invention also concerns a portable electronic device and a device for acquiring biometric data for implementing the method.
