Abstract

L'invention concerne un système destiné à la gestion des droits relatifs à un ou plusieurs fichiers de contenu numérique dans un réseau informatique, permettant la lecture en ligne de ces fichiers de contenu par un utilisateur autorisé. Pour gérer ces droits, le système code les fichiers de contenu afin d'empêcher tout accès non autorisé aux fichiers. Le codage s'effectue à l'aide d'une ou de plusieurs clés associées à un ou plusieurs segments du fichier de contenu. Ces clés permettent à un utilisateur autorisé de décoder et de lire les fichiers de contenu ultérieurement. Lorsqu'il reçoit les clés, un système d'utilisateur final récupère une licence d'un serveur de licences précisant les droits de l'utilisateur vis à vis des fichiers de contenu.
