Problems solved by technology

For example, a rights object that allows user A to use content does not allow user B who has this rights object to use the content.
For example, when a mobile node in domain E is moved to domain F and content in a device therein is used, how an available rights object in domain E should be used becomes an issue.
In addition, even when the rights object is not available in units of a domain, it is not easy for other devices to acquire a rights object without an infringement of copyright.
Accordingly, this can be a major obstacle to the distribution of DRM systems.

Abstract

A method of enabling roaming of a rights object in a digital rights management (DRM) system is provided. The method includes issuing disposable authentication information to a mobile device, receiving a request for a remote authentication as well as the authentication information from an unauthorized device, transmitting a query required for the remote authentication to the unauthorized device, receiving a response to the query from the unauthorized device, and transmitting data that approves of the authentication of the unauthorized device to the unauthorized device.

Description of the Related Art[0005]DRM was introduced as a way of protecting digital content under copyright. Conventionally, DRM has been applied to the content but the emphasis has gradually changed to the rights object that controls content consumption or use.[0006]In DRM, content can be constrained depending on who owns the rights object. For example, a rights object that allows user A to use content does not allow user B who has this rights object...
