This invention relates to a method of processing rights relating to content, that can be communicated between devices. Typically, a Digital Rights Management (DRM) system imposes limitations of use and distribution, imposed by the service provider, content provider or distributor. The method of the invention renders it possible for a user who has received DRM rights to restrict the right further. The invention is more particularly related to the receipt of DRM rights to Authorized Domain Digital Rights Management (AD-DRM) systems and the introduction of user attributed rights in the form of further restrictions introduced to the received DRM rights. The invention further relates to a Rights Program Template (RPT) facilitating the introduction of such further restrictions in a user friendly way. Finally, the invention relates to a system supporting the method of the invention.
