ABSTRACT:
Provided is a method for delivering all or part of a rights object (RO) of a user associated with the content to other users. The method includes creating a rights object to be transmitted to a second user within a limit of the rights object held by the first user, and forwarding the created rights object to the second user. The method allows each user to share its own RO with other users within the limit of the RO without server authentication.
