Method and apparatus for prevention of tampering and unauthorized extraction of information from microdevices

A system for prevention of tampering, unauthorized use, and unauthorized extraction of information from at least one secured microdevice device, comprising:

• a control unit arranged to generate a command to trigger a controlled obliteration of at least a fraction of stored information on the at least one secured microdevice;
• an obliteration driver arranged to store electric energy and to generate, when triggered by the control unit, at least one pulse of electric current;
• a circuit arranged to conduct the at least one pulse of electric current toward at least one resistive dissipative load structure arranged in a proximity of the at least the fraction of stored information on the at least one secured microdevice, and connected to controllably release the delivered portion of stored electric energy in the proximity of the at least the fraction of stored information on the at least one secured microdevice, such that the at least the fraction of stored information has been obliterated during the controllable release;
• wherein, the circuit arranged to conduct the at least one pulse of electric current incorporates at least one resistive load having a localized predetermined resistance and at least one coupling structure, 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, transferred through the at least one coupling structure, and controllably applied upon the proximity of the at least the fraction of stored information on the at least one secured microdevice, such that the at least the fraction of stored information has been obliterated during the controllable release.

• a control unit arranged to generate a command to trigger a controlled obliteration of at least a fraction of stored information on the at least one secured microdevice;
• an obliteration driver arranged to store electric energy and to generate, when triggered by the control unit, at least two distinct pulses of electric current;
• a circuit arranged to conduct the at least two distinct pulses of electric current toward at least two resistive dissipative load structures arranged in a proximity of the at least the fraction of stored information on the at least one secured microdevice, and connected to controllably release the delivered portions of stored electric energy in the proximity of the at least the fraction of stored information on the at least one secured microdevice, such that the at least the fraction of stored information has been obliterated during the controllable release;
• wherein, the circuit arranged to conduct the at least two distinct pulses of electric current incorporates a plurality resistive loads each having a localized predetermined resistances and at least one disconnecting element, such that the portion of stored electric energy, delivered by at least one pulse of electric current, 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 while switching the at least one disconnecting element into an open nonconductive state regarding any subsequent pulse of electric current.
