Lock with tamper-evident security
A safe with lock tampering capabilities is provided. A lock apparatus includes a lock body, a lock backplate, a lock, and a sensor. The sensor raises an event when a first end and/or a send end of the sensor loses contact with a surface of the lock body and/or a surface of the lock backplate. The event is reported by the safe as a lock tampering event. Whenever the safe loses power and is subsequently restored power, the safe reports a lock tampering event.
1. A safe, comprising:
a housing comprising media cassettes that store currency notes;
an access door on the housing to provide authorized access to the media cassettes;
a display or keypad affixed to an external surface of the access door,
a lock apparatus comprising a lock backplate, a lock body, a sensor, and a lock integrated into the access door and the lock body, wherein a portion of the lock body is secure attached to an inside surface of the access door;
a processor;
a non-transitory computer-readable storage medium comprising executable instructions;
the executable instructions when executed by the processor cause the processor to perform operations comprising:
detecting a lock tampering event raised by the sensor when a surface of the lock backplate is no longer in contact with the sensor indicating that the lock backplate was removed from the lock body; and
reporting the lock tampering event when the safe is restored power after having lost power;
wherein the sensor is anchored on an inside surface of the lock body proximate to the lock and includes a first end anchored to the lock body extending to a second end that makes surface contact with the lock backplate.
2. The safe of claim 1 , wherein the executable instructions when executed by the processor further cause the processor to perform additional operations comprising:
resetting the lock tampering event based on an authorization code received from a terminal or server after the power is restored and the lock tampering event was reported to one or more of the terminal and the server.
3. The safe of claim 1 , wherein the safe is integrated into a media recycler or dispenser.
4. The safe of claim 3 , wherein the media recycler or dispenser is a peripheral device of a media terminal.
5. The safe of claim 4 , wherein the media terminal is an automated teller machine, a self-service terminal, or a point-of-sale terminal.
6. The safe of claim 1 , wherein the sensor is a contact sensor that makes contact with a surface of the lock body and a surface of the lock backplate when the lock body is interlocked with the lock backplate on the inside surface of the safe door.
7. The safe of claim 1 further comprising:
an external network connection to a server; and
an internal network connection to a media recycler or dispenser;
wherein the safe is a peripheral device of the media recycler or dispenser, and wherein the media recycler or dispenser is a peripheral device of a media terminal.
8. The safe of claim 7 , wherein the executable instructions when executed by the processor further cause the processor to perform additional operations comprising:
receiving an access authorization code via the display or the keypad;
authenticating the access authorization code with the server over the external network connection and receiving access details for the access authorization code from one or more of the server and the media terminal;
controlling the lock apparatus to unlock the lock and open the safe door when the server authenticates the access authorization code; and
logging or reporting the access details.
