CA 2256373

The present invention relates to an electronic anti-theft device for computers and other processor-assisted electronics, such as memory components, hard disks, plug-in boards and processors. The anti-theft device comprises a blocking-circuit which is integrated with the component to be protected, said circuit comprising a memory for storing a specific identity code (ID-code) for each blocking circuit. In addition, the circuit comprises an input for inputting a key code into the circuit, and a comparator for comparing the introduced key code with the ID-code of the circuit, the circuit being adapted to block the component from further use in case of an incorrect key code.

La présente invention concerne un dispositif électronique antivol destiné à des ordinateurs et autres composants électroniques assistés par un processeur, tels que des mémoires, disques durs, des cartes enfichables et des processeurs. Ce dispositif antivol comprend un circuit de blocage intégré dans le composant à protéger, ce circuit comportant une mémoire destinée à stocker un code d'identité spécifique (code ID) servant pour chaque circuit de blocage. En outre, ce circuit présente une entrée servant à entrer un code d'identification dans le circuit, ainsi qu'un comparateur servant à comparer le code d'identification introduit avec le code d'identité spécifique du circuit, et il est conçu pour bloquer le composant et empêcher l'utilisation de celui-ci, en cas d'entrée d'un code d'identification incorrect.
