Title
(EN) METHOD FOR REDISTRIBUTING DRM PROTECTED CONTENT
(FR) PROCEDE POUR REDISTRIBUER UN CONTENU PROTEGE PAR DRM
Abstract
(EN)
The present invention relates to a method and a device (207) for providing a party (214) with a content item license (202). A basic idea of the present invention is to enable redistribution of, or giving away/gifting of, digital content items while satisfying DRM requirements. Hence, determining means in the form of e.g. a proximity verifier receives authentication data of a first party (213) wishing to give away or redistribute a content item (215). The proximity verifier also receives authentication data of a second party (214) to which the content item is to be transferred. Further, a license (202) associated with the content item and the first party is received at the proximity verifier (207) from the first party. The license may be associated with the first party and the content item by a first party identifier (203) and a content item identifier (204) comprised in the license. The proximity verifier determines whether the first party and the second party are in physical proximity to each other. If that is the case, the verifier creates a new license (212) associated with said content item (215) as well as with the second party (214), and revoking the license (202) associated with the first party (213).

La présente invention concerne un procédé et un dispositif (207) pour fournir un permis d'élément de contenu (202) à une partie (214). Une idée de base de l'invention est de permettre la redistribution ou le don d'éléments de contenu numérique tout en satisfaisant aux critères DRM. Ainsi, un moyen de détermination, prenant la forme par exemple d'un vérificateur de proximité, reçoit les données d'authentification d'une première partie (213) souhaitant donner ou redistribuer un élément de contenu (215). Le vérificateur de proximité reçoit également des données d'authentification d'une seconde partie (214) à laquelle l'élément de contenu doit être transféré. De plus, une licence (202) associée à l'élément de contenu et à la première partie est reçue sur le vérificateur de proximité (207) de la première partie. La licence peut être associée à la première partie et à l'élément de contenu d'un premier identifiant de partie (203), ainsi qu'à un identifiant d'élément de contenu (204) compris dans la licence. Le vérificateur de proximité détermine si la première et la seconde partie sont en proximité physique l'une de l'autre. Dans l'affirmative, le vérificateur crée une nouvelle licence (212) associée à l'élément de contenu (215) ainsi qu'à la seconde partie (214) et révoque la licence (202) associée à la première partie (213).
