Abstract

L'invention concerne un dispositif de traitement d'informations dans lequel une unité de commande d'affichage (22a) affiche une fenêtre de dialogue. Ensuite, lorsqu'un dossier chiffré doit être déchiffré, un utilisateur appuie sur un bouton « Ouvert » qui est disposé sur la fenêtre de dialogue et est associé au dossier chiffré. Lorsque l'utilisateur appuie sur le bouton « Ouvert », une unité de réception (25) reçoit cette opération de pression et détermine si un réglage dissimulé a été mis sur « Marche » pour le dossier associé au bouton « Ouvert ». Si le réglage dissimulé a été mis sur « Marche » pour le dossier, alors une unité de développement (26) développe le dossier et affiche le dossier développé dans une fenêtre d'affichage. Une unité de commande de déchiffrement (27) déchiffre ensuite les fichiers dans le dossier selon un ordre prédéterminé.
