Abstract

L'invention porte sur un serveur de gestion de contenu électronique (20) qui est connecté à une pluralité de terminaux utilisateur par l'intermédiaire d'un réseau de communication afin de gérer l'utilisation de contenus électroniques, et qui comprend une base de données d'informations de droit d'utilisation servant à stocker les informations de droit d'utilisation pour un contenu électronique. Une unité centrale (CPU) (21) gère la pluralité de terminaux utilisateur d'une manière telle que chaque terminal utilisateur peut utiliser seulement un contenu électronique pour lequel chaque terminal utilisateur possède le droit d'utilisation, sur la base des informations de droit d'utilisation stockées dans la base de données d'informations de droit d'utilisation, et lorsque, parmi la pluralité de terminaux utilisateur, un premier terminal utilisateur propose à un second terminal utilisateur de prêter temporairement le droit d'utilisation pour un contenu électronique possédé par le premier terminal utilisateur, le droit d'utilisation pour le contenu électronique est temporairement prêté au second terminal utilisateur par modification des informations de droit d'utilisation pour le contenu électronique dans la base de données d'informations de droit d'utilisation. De ce fait, le droit d'auteur d'un contenu peut être suffisamment protégé pendant que l'utilisation du contenu peut être réalisée par un tiers.
