Abstract
A smart card includes a plurality of application circuits that are each related to at least one application service securely contained within the card, each application circuit is energizable by an outside signal; a control unit making it possible to identify the energized application circuit and the related service and moreover to activate the service in response to activation authorization; and a biometric circuit for authenticating the user so as to generate the activation authorization.
Claims11
A secured communication device, comprising:
- a plurality of application circuits which are each related to at least one application service securely contained within the device, each application circuit being excitable by an external signal;
- a control unit making it possible to identify the excited application service, the related service and to activate said service in response to an activation authorization;
- and
- a biometric circuit for authenticating the user so as to generate said activation authorisation.
A method implemented in a secured communication card including a plurality of application circuits, a control unit and a biometric circuit;
- the method including the following steps:
- an excitation external signal is detected by means of one of the application circuits, each application circuit being related to at least one application service securely contained within the card;
- and
- within the control unit, the excited application circuit and the application service related to this excited application circuit are identified, and an authentication process is started by biometric comparison within the biometric circuit, and then said excited application circuit is activated in response to an activation authorization from the biometric circuit.
