CA 2571848

.A security system and method is provided. An embodiment includes a security access device that includes a first transmitter for transmitting authentication to a computer and a second transmitter for transmitting verification information to a computer. The first transmitter is typically active and consumes power from the access device, while the second transmitter is typically passive, and consumes less or nil power from the access device. When the security access device is initially brought proximal to the computer and activated, the authentication information is sent to the computer and the user is logged in. Periodically, the computer will query the passive transmitter for verification information, to ensure that the security access device is still proximal to the computer.

L~invention concerne un système et un procédé de sécurité. Un mode de réalisation comprend un dispositif d~accès de sécurité qui comprend un premier émetteur pour transmettre une authentification à un ordinateur et un second émetteur pour transmettre des informations de vérification à un ordinateur. Le premier émetteur est actif en règle générale et consomme une puissance provenant du dispositif d~accès, tandis que le second émetteur est passif en règle générale et consomme moins de puissance ou aucune provenant du dispositif d~accès. Lorsque le dispositif d~accès de sécurité est initialement amené à proximité de l~ordinateur et activé, les informations d~authentification sont envoyées à l~ordinateur et l~utilisateur est connecté. Périodiquement, l~ordinateur interrogera l~émetteur passif pour des informations de vérification, afin de s~assurer que le dispositif d~accès de sécurité est toujours à proximité de l~ordinateur.
