Abstract
Apparatus, method and program product detect an attempt to tamper with a microchip by determining that an electrical path comprising one or more connections and a metal plate attached to the backside of a microchip has become disconnected or otherwise altered. A tampering attempt may also be detected in response to the presence of an electrical path that should not be present, as may result from the microchip being incorrectly reconstituted. Actual and/or deceptive paths may be automatically selected and monitored to further confound a reverse engineering attempt.
