A system for protection of information on a secured microdevice, including a control unit, an obliteration driver, and a circuit arranged to conduct the at least one pulse of electric current. The circuit incorporates at least one resistive load having a localized predetermined resistance such that the delivered portion of stored electric energy is locally resistively converted into a mechanical energy of motion during a time period shorter than a duration of time needed for heat diffusion out a volume in the proximity of the at least the fraction of stored information.
