Abstract: PURPOSE: A content rights protecting method is provided to easily perform the access and use of a legitimate user about contents. CONSTITUTION: A digital rights management (DRM) agent determines whether a content which a user requests to a device has integrity or not (S110). The DRM agent collects a content identifier of a content which has integrity, a time at which the use of the content is requested, and content user location information of the time which is requested to use (S120). The DRM agent transmits the collected information to a server. The server determines whether 'a different content which has a content identifier which is same with the obtained content identifier' is used in a different place or not by using the transmitted time and location information (S130). [Reference numerals] (AA) Start; (BB) End; (S110) Determine whether there is integrity of contents or not; (S120) Collect the identifier, sight, and location information of contents; (S130) Determine whether the same content identifier is used or not
