Abstract

A method, device and system for stably issuing a rights object (RO) to a memory, namely, an SRM, via a terminal. When RO has been issued to the memory card, namely, to the SRM, by using the stable procedure, the RO can be compatible with a different terminal that does not support the stable procedure, whereby the RO can be completely used by the different terminal.

Description

technical field [0001] The present invention relates to digital rights management (DRM) and more particularly to methods, devices and systems for directly downloading and installing rights objects in a DRM environment. Background technique [0002] Digital Rights Management (DRM) is a technology that securely protects and systematically manages rights objects of digital content (eg, music, movies, documents, images, etc.). DRM prevents unauthorized and / or illegal copying of digital content. DRM also provides acquisition of Rights Object (RO) of DRM content, production and distribution of DRM content, and protection and management of a series of use processes. [0003] figure 1 The general structure of a conventional DRM system is shown. [0004] Conventional DRM systems control how users receive and process received digital content according to ROs given to users. In this regard, a content provider is an entity that corresponds to a content issuer (CI) 30 and / or a rights...
