Abstract

A method for protecting a rights object for a content, wherein when a discard of a rights object with respect to a certain content is requested due to a missing of a terminal which stores the rights object with respect to the content, a rights issuer (Rl) receives a confirmation request for whether a certificate has been discarded from the terminal, confirms the certificate discard through an Online Certificate Status Protocol (OCSP) responder, and then notifies the terminal of the certificate discard, and accordingly the terminal confirms the discard of the certificate of the terminal and removes the rights object with respect thereto. In addition, a user who has removed the rights object with respect to the content can continuously use the corresponding content by entirely or partially re-obtaining the rights object with respect to the content from which the rights object has been discarded.
