Patent

CA 2371334

A device and method for protection of legitimate software against used software and counterfeit software in recording media. The device includes a disk set in a main unit. A specific title code is used, and if this title code has been registered, the main unit shifts to a normal operation. If the code has not been registered, verification software is initiated, PG detection is performed, and when a PG pattern and verification data match, the code is registered in the COCT. If matching does not occur, the disk is processed as illegitimate software.

La présente invention concerne un dispositif et un procédé de protection de logiciels authentiques contre des logiciels déjà utilisés ou contrefaits dans un support d'enregistrement. Ce dispositif comprend un disque placé dans une unité principale. Un code d'appellation spécifique est lu. Si ce code d'appellation a été enregistré, l'unité principale passe à une opération normale. En revanche, si le code n'a pas été enregistré, la vérification du logiciel s'enclenche, la détection PG s'effectue, et lorsqu'un motif PG et des données de vérification correspondent, le code est enregistré dans le COCT. Si la correspondance n'a pas lieu, le disque est traité comme un logiciel non authentique.
