Method and optical shield for detecting tampering

A system comprising:

• an optical fiber with a first end and a second end, the optical fiber conformed to an object, the object comprising a container having multiple parts that physically alter the optical fiber when the container or at least one of the multiple parts is tampered with;
• a detachable light source configured to emit a light pulse, the optical fiber configured to receive the light pulse at the first end and emit an optical signature at the second end;
• a detachable optical spectral analyzer configured to capture a current optical signature from the second end, the optical spectral analyzer in communication with a data store, the optical spectral analyzer comprising a processor configured to:
• retrieve a stored optical signature from the data store, the stored optical signature captured from the second end when the light pulse was applied to the first end prior to the detachable optical spectral analyzer capturing the current optical signature from the second end,
• determine whether a difference between the current optical signature, captured from the second end of the optical fiber and resulting from the light pulse at the first end, and the stored optical signature, captured from the second end of the optical fiber and resulting from the light pulse at the first end, exceeds a threshold, and
• determine that at least one of the container or the multiple parts has been tampered with based on the difference exceeding the threshold.
