摘要： A method of detection of unauthorized intervention into an identification structure is provided. The method includes configuring the identification structure such that the identification structure interacts with the intervention such as a physical intervention, or mechanical intervention, or electrical intervention. Further, the method involves propagating the intervention along the identification structure in such a control as to cause a detectable alteration in any predetermined attributes associated with the identification structure including a physical attribute, mechanical attribute, electrical attribute, and an optical attribute. Finally, the alteration in the attributes is detected by visual, electrical, or optical assessments or a combination of assessments.
