Patent ID: 8332661

Claim:
A method for prevention of tampering, unauthorized use, and unauthorized extraction of information, from at least one information containing region of a secured microdevice in a processing device by controlled obliteration of said information comprising the following steps: (a) implementing control protocols and hardware which generate at least one command to trigger said controlled obliteration of said information; (b) establishing of a local energy storage device which stores energy in a form of localized electromagnetic fields to be used to initiate and perform said controlled obliteration of said information; (c) establishing of localized controlled release of the stored energy from the local energy storage device and at least partial deposition of the stored energy in a proximity of the at least one information containing region of the secured microdevice, upon generation of said at least one command to trigger said controlled obliteration of said information; (d) maintaining of conditions for controlled release of the energy stored in the local energy storage device upon generation of said command to trigger said controlled obliteration of said information for the duration of time necessary to achieve desired controlled obliteration of said information; wherein the at least partial deposition of stored energy in a form of localized electromagnetic fields in the proximity of the at least one information containing region of the secured microdevices is maintained for a period of time shorter than the time needed for a heat from the energy released in the proximity of the at least one information containing region of the secured microdevice to diffuse through a volume of the at least one information containing region of said secured microdevice.
