Title (EN) PREVENTING UNAUTHORIZED USE OF DEVICES
(FR) PRÉVENTION D'UTILISATION NON AUTORISÉE DE DISPOSITIFS
Abstract:
(EN) Unauthorized use of a secured device can be prevented using customized hardware that only permits operation of the secured device while an enable signal is being generated, and prevents its operation at all other times. The enable signal is only generated when variations in incoming ultrasound waves indicate that a specific ultrasound activation signal has arrived. This ultrasound activation signal is generated by an activation unit that is acoustically coupled into an ultrasound conductive body (e.g., a person's body). Because the ultrasound activation signal cannot cross air gaps, the ultrasound activation signal will only be able to reach its destination when both the activation unit and the secured device maintain acoustic contact with the ultrasound conductive body. In addition, the signal that is actually received by the secured device must be the same specific ultrasound activation signal that the secured device is expecting to receive.
(FR) L'utilisation non autorisée d'un dispositif sécurisé peut être empêchée à l'aide d'un matériel personnalisé qui permet le fonctionnement du dispositif sécurisé uniquement pendant qu'un signal de validation est généré, et qui empêche son fonctionnement à tout autre moment. Le signal d'activation n'est généré que lorsque des variations d'ondes ultrasonores entrantes indiquent qu'un signal d'activation ultrasonore spécifique est arrivé. Ce signal d'activation ultrasonore est généré par une unité d'activation qui est couplée acoustiquement à un corps conducteur ultrasonore (par exemple, le corps d'une personne). Du fait que le signal d'activation ultrasonore ne peut pas traverser des espaces d'air, le signal d'activation ultrasonore pourra uniquement atteindre sa destination lorsque l'unité d'activation et le dispositif sécurisé maintiennent un contact acoustique avec le corps conducteur ultrasonore. De plus, le signal qui est réellement reçu par le dispositif sécurisé doit être le même signal d'activation ultrasonore spécifique que celui que le dispositif sécurisé s'attend à recevoir.
