DEVICE AND METHOD FOR DISABLING ELECTRONIC DEVICES
Document Type and Number:
WIPO Patent Application WO2003066248
Kind Code:
A3
Abstract:
The invention relates to a device and a method for disabling electronic devices in order to reliably prevent third parties from gaining unauthorized knowledge of data in the event of loss of the storage medium. The device comprises a gas generator, with a pyrotechnic propelling charge, disposed in the area of the storage medium. At least one fuel or at least one oxidator of the propelling charge releases, when the latter is triggered, well conducting metals, especially precious or semi-precious metals which are deposited on the electronic parts of the electronic device. According to the inventive method, the igniter can be triggered manually, by sensors or remote-controlled. The invention further relates to an electronic data processing system and a telephone comprising such a device.
