  • Method for controlling authorization to an object and a computer program product for the authorization control
    Patent number: 7859386
    Abstract: Method and arrangement for controlling authorization for access to an object, in which a signal communication via electromagnetic waves is established between the object and a wireless portable unit when a tripping device on the object is actuated. The signal communication includes at least one first signal (X1 . . . Xn) that is sent from the object to the portable unit, and at least one second signal (Y3, Z1 . . . Zn) that is sent from the portable unit to the object in response to the first signal(s). The second signal(s) includes sufficient information for verifying that the portable unit has an approved identity. The verification information is checked, a distance is measured between the object and the portable unit and the authorization is confirmed if both the checked verification information is approved and the measured distance is less than a predetermined value.
