Abstract: An anti-tamper system includes a first object, second objects, and an anti-tamper circuit that includes conductive networks and a control unit. Each conductive network includes: conductive modules, each of which is sandwiched between the first object and a corresponding second object; and conductive connection members which are coupled to the conductive modules in such away that at least the conductive modules and the conductive connection members cooperatively form a corresponding electrical path sequentially going through the second objects. The control unit detects damage of each electrical path, and initiates a predetermined action upon detecting the damage.
