Abstract
The present invention provides an apparatus and method for detecting if a person has attempted to tamper with an integrated circuit (IC). The apparatus is located on the IC and comprises detection circuitry that detects a build up of electrical charge on the IC and disablement circuitry that disables the IC when the detection circuitry detects a build up of electrical charge on the IC. The method comprises detecting if a build up of electrical charge on the IC has occurred and disabling the IC when a build up of electrical charge on the IC has been detected.
