ABSTRACT:
A method and apparatus for inhibiting unauthorized access to or utilization of a container or other protected device wherein a free standing lock or other control is provided, the state of which may be varied in response to receipt of a dynamic non-predictable code. The device may be a lock which when in a first state locks the container or other device, but which may switch to an unlocked state in response to verification that an authorized dynamic non-predictable code has been received. Alternatively, the control may be a mechanism integrally formed with the protected device which, when in a first state, inhibits and prevents normal operation of the device, permitting such operation when the mechanism is in its second state. The non-predictable code may be produced by a token carried by an authorized user, may involve query response operations, or may otherwise be generated in manners known in the art.
