1. An electronic security device, comprising:
- a mechanical fastener configured to physically secure a container latch in a closed position;
at least one non-zero electrical resistor embedded in said mechanical fastener, wherein said non-zero electrical resistor has a resistance value that changes when said mechanical fastener is tampered with; and
electronics, circuitry, and a digital memory that contains a unique electronic identification code for said electronic security device, wherein said electronic identification code is combined with said resistance value of said non-zero electrical resistor to create a unique seal identification code when said electronic security device is fastened to said container latch;
wherein the resistance value is randomized based on a randomized embedded length of the non-zero electrical resistor, the randomized embedded length being embedded in said mechanical fastener.

Abstract
A tamper-proof bolt-seal incorporating a unique identification tamper detection sensor that cannot be restored or duplicated after the bolt. The sensor employs a resistive sensor wire embedded in the bolt. The resistive sensor wire has a randomized length to enable a unique resistive value for that sensor. The resistive value of the sensor is combined with an electronic identification code to create the unique seal identification for the tamper detection sensor, therefore giving the bolt a seal identification that is unique and that cannot be restored or duplicated.

17. A method for detecting a breach attempt on an electronic security device, said method comprising the steps of:
-
attaching said electronic security device to a container latch to establish a continuity circuit for said electronic security device, wherein said continuity circuit has a baseline resistance value that is a unique baseline resistance value based on a randomized embedded length of an electrical resistor that is embedded in a mechanical fastener of said electronic security device; generating a unique seal identification based in part on said baseline resistance value of said continuity circuit and an electronic identification code associated with said electronic security device; recording said unique seal identification to a data store as an original seal identification; scanning said electronic security device to obtain a current seal identification of said electronic device; comparing said current seal identification to said original seal identification; and issuing an identification mismatch alert for any mismatch between said current seal identification and said original seal identification. - View Dependent Claims (18)
