Method of detection of unauthorized intervention in an identification structure which is designed to aid such detection

An identification structure for detecting unauthorized intervention, the unauthorized intervention being a physical intervention, an electrical intervention or a combination thereof, the identification structure comprising:

• a plurality of layers stacked together;
• and
• a plurality of identification elements selected from a group comprising physical elements, electrical elements, optical elements, and combinations thereof, with the plurality of identification elements being selectively positioned on different layers of the plurality of layers for interaction with the intervention, wherein
• a top layer of the plurality of layers provided with the physical elements having a predetermined depth for propagating the intervention along different layers of the identification structure in a manner such as to cause a propagation of the intervention in a controlled manner so that the unauthorized intervention leaves behind a signature of a detectable alteration in a corresponding attribute of any one or more of the identification elements, and in a manner such that at least one of the identification elements is retained intact without damage.
