Electronic tampering detection system

An electronic alteration detection system is applied to the blank which can be formed in the form of a package through use of the closing tab coated using conductive adhesive. An electronic chip or CPU is attached blank, and electric conduction trace is printed on a blank, or it is formed with an option, and CPU is connected to the 1st closing tab pairs, and an electric circuit is formed. Other traces on a blank connect the 1st closing tab pairs to other closing tabs, and the widened circuit is formed. CPU has a procedure memory, data memory, a power supply, a clock, and a means of communication relevant to it. When a package is opened wide by chance or intentionally before the time of opening wide with a closing tab, an electric circuit is disconnected, and in order that the time stamp from a CPU clock may search later, data memory memorizes. A circuit can be formed as parallel resistance and can supply a suitable signal to CPU using an analog-to-digital converter. The electric circuit can supply the signal in the penetration event to which covers the great portion of blank surface, and the formed package is not permitted.
