Abstract

L’invention décrit un système de téléchargement et de distribution de contenus, dans lequel système la copie non autorisée de fichiers de contenu peut être supprimée. Un dispositif de lancement (8) a été installé dans un terminal utilisateur (5). Le dispositif de lancement (8) acquiert des informations matérielles inhérentes du terminal utilisateur (5) et enregistre, sous forme d’informations du registre local (10), et stocke un ID utilisateur, un mot de passe et les informations matérielles inhérentes. Dans le cas du téléchargement d’un contenu, le contenu une fois téléchargé est décompressé, et l’ID utilisateur et les informations matérielles inhérentes des informations du registre local (10) sont ajoutées au contenu, lequel est ensuite à nouveau décompressé et stocké. Dans le cas du lancement d’un contenu, le contenu est décompressé, et un ID utilisateur et les informations matérielles inhérentes sont extraites du contenu. Ensuite, l’ID utilisateur et les informations matérielles inhérentes extraites du contenu sont comparés à l’ID utilisateur et aux informations matérielles inhérentes des informations du registre local (10), et uniquement lorsqu’ils coïncident les uns avec les autres, le contenu est lancé.
