Patent

CA 2538850

The record carrier of the present invention has a storage area for storing data. The record carrier receives an access requisition to the storage area from a terminal device having the record carrier attached thereto, acquires an access condition indicating authorization to access the storage area, judges whether or not the access requisition satisfies the access condition. When confirming that the access requisition does not satisfy the access condition, the record carrier prevents the access to the storage area. This allows for preventing an unauthorized user from accessing the data stored inside in the case where the record carrier is lost.

L'invention concerne un support d'enregistrement comprenant une zone de stockage permettant de stoker des données. Ledit support d'enregistrement reçoit une demande d'accès à la zone de stockage provenant d'un dispositif de terminal auquel est fixé le support d'enregistrement, acquière une condition d'accès indiquant une autorisation d'accès à la zone de stockage et juge si la demande d'accès satisfait ou non la condition d'accès. Lorsqu'il est confirmé que la demande d'accès ne satisfait pas la condition d'accès, le support d'enregistrement empêche l'accès à la zone de stockage, ce qui interdit à un utilisateur non autorisé d'accéder aux données stockées à l'intérieur dans le cas où ledit support d'enregistrement est perdu.
