A method of managing content, the method being performed by a device
including an analyzing unit and a control unit. The method includes
judging, via the analyzing unit, whether the content can be moved to an
external entity based on moving control information, the moving control
information being different from copy control information indicating
whether the copy of the content is permitted, determining whether an
authentication with the external entity is needed in order to move the
content to the external entity, if the judging step judges that the
content can be moved, and controlling, via the control unit, a moving
operation of the content to the external entity such that the content can
be moved to the external entity without the authentication if the
determining step determines the authentication is not needed.
