摘要
A device for managing a rights object and revoking a content object. The device includes a content/rights object storage unit for storing at least one content object, and a rights object corresponding to each content object. An authentication module performs mutual authentication between devices giving and taking a rights object, and when a revocation notification of a rights object among the stored rights object is received, authenticates whether an author having transferred the revocation notification is an author having a revocation right. A content object checking unit checks if the content object is valid before the content object is executed. A rights object management module searches for a rights object corresponding to a content object to be executed, and deletes a rights object corresponding to the revocation notification when the author is an author having the revocation right. A controller controls the modules and the units.
