发明名称 METHOD FOR REDISTRIBUTING DRM PROTECTED CONTENT
摘要 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).
