Abstract
For the usage of the different standard technology among DRM vendors, the DRM technologies in today could not guarantee the interoperability between the digital contents and digital devices. While users have been guaranteed the protection of contents, they have to put up with the limitation and inconvenience. The Superdistribution methods that InterTrust has proposed is the content distribution technology which is possible to use the content only by the user authentication with the license regardless of the acquisition of the DRM contents. However, it need a additional license with re-authentication from DRM server when the original contents need to be moved to other devices from the own device. In this paper, to reduce the inconveniences of re-authentication and re-issue procedures of the license and continually to protect the rights of contents on the offline, we propose the DRM system that creates domain between home devices and enable users to freely transfer contents with the domain.
