Title (EN) PERSONAL COMPUTER HARD DISK PROTECTION SYSTEM
(FR) SYSTEME DE PROTECTION DE DISQUES DURS D'ORDINATEUR PERSONNEL
Abstract:
(EN) The personal computer hard disk protection system (220) is designed to protect data stored on computer hard disks (34) of computers utilizing non-ISA buses while permitting multiple user operation. The personal computer hard disk protection system (220) prevents unauthorized access to the hard disk (34) by software applications, and permits safe servicing of requests which use the BIOS. The basis for the personal computer hard disk protection system (220) functions is the dynamic transformation of the file system to the configuration of the current user. The system (220) is based on a hardware device called the protection-program support module (222) and a set of protection programs (24), most of which is stored in the protection-program support module (222). The protection program support module (222) is an external board and is connected to the computer system bus (58, 60, 62), and to the base IDE connection level, the latter of which is controlled by the protection program support module (222) for either permitting or denying access to the hard disk (34).
(FR) L'invention porte sur un système de protection (220) de disques durs d'ordinateur personnel protégeant les données enregistrées sur les disques durs d'ordinateurs à bus non ISA tout en permettant leur exploitation par plusieurs utilisateurs. Ledit système (220) empêche l'accès non autorisé au disque dur par l'intermédiaire de logiciels tout en permettant le traitement protégé des demandes utilisant le BIOS (système de base entrée/sortie). Le principe du système de protection (220) repose sur la transformation dynamique du système de fichiers par rapport à la configuration de l'utilisateur actuel. Le système (220) est basé sur un dispositif logiciel (222) appelé module de support (222) de programmes de protection et sur un ensemble de programmes de protection (24) presque tous chargés dans le susdit module (222) qui est constitué par un circuit extérieur relié au système de bus (58, 60, 62) de l'ordinateur et au niveau de connexions IDE dont le dernier est commandé par le module support (222) pour permettre ou refuser l'accès au disque dur (34).
