Multimedia rights management for the multiple devices of end-user

This paper describes multimedia rights management enforcement for the multiple devices of end-user. Today, contents sharing and superdistribution of the multiple devices has become easy due to advancement in computer technology. However, most DRM vendors require only DRM client system of their own then end-user must have installed various clients and may worry about limited computing capacity. And the DRM vendors may worry that end-users could give or lend the multimedia rights of protected contents to device of another user what the DRM vendors don't allow. To resolve these problems, we propose a multimedia rights management scheme in which multiple devices of end-user are managed by only proxy manager controlled with interoperable client of each device. This scheme supports rights governance by public key based group communication that ensures that only legitimate operations can apply to the multimedia content.
