Abstract

L'invention concerne une carte de données et un procédé associé d'accès multi-utilisateurs d'une carte de stockage externe. Lorsqu'un utilisateur accède à un stockage externe, la carte de données recherche dans la carte de stockage externe un fichier auquel l'utilisateur a le droit d'accéder conformément à l'attribut d'identité de l'utilisateur, et affiche le fichier à l'attention de l'utilisateur. Lorsqu'il est détecté que l'utilisateur crée un fichier dans la carte de stockage externe ou télécharge avec succès un fichier dans la carte de stockage externe, l'utilisateur est invité à définir une autorisation d'accès pour le fichier. L'invention classe l'utilisateur conformément à l'attribut d'identité, et lorsque l'utilisateur vient de créer un fichier dans le stockage externe ou télécharge avec succès un fichier vers le stockage externe, l'utilisateur est invité à définir une autorisation d'accès pour le fichier nouvellement créé ou téléchargé, ce qui permet de garantir, outre le fait qu'un utilisateur ayant l'attribut d'identité est un administrateur, que le fichier dans la carte de stockage externe peut être parcouru, téléchargé ou supprimé uniquement par l'utilisateur ajoutant le fichier ou un utilisateur autorisé. L'invention protège efficacement les données privées de l'utilisateur.
