Abstract

A host device and a method of implementing Digital Rights Management (DRM) systems in a low-efficiency storage device are provided. The host device includes a plurality of DRM systems and a DRM system-shared interface module. The DRM systems provide pieces of DRM-related data and data identifiers (IDs) which identify the pieces of data. The DRM system-shared interface module adds DRM system IDs, which are used to identify the DRM systems, to the pieces of data and the data IDs, and provides results, which are obtained by adding the DRM system IDs, to a low-efficiency storage device.

Description

[0001] This application claims priority from Korean Patent Application No. 10-2005-0114983 filed in the Korean Intellectual Property Office on Nov. 29, 2005, which is hereby incorporated by reference. technical field [0002] Apparatus and methods according to the present invention relate to digital rights management (DRM), and more particularly, to implementing multiple DRM systems in inefficient storage devices. Background technique [0003] Recently, research on DRM has been actively conducted, and business services to which DRM is applied have been proposed or are being proposed. DRM is a technical concept for protecting digital content that is easily copied and distributed illegally. [0004] Although efforts have been made in the past to protect digital content, these efforts have been based on preventing illegal access to digital content. [0005] For example, only users who have paid for the digital content are allow...
