A method of moving a rights object according to the present invention includes the following steps. First, a rights object in the memory card is disabled. Then, the rights object is copied from the memory card in response to a retrieval request and installed to a content player. After the installation, a removal request is transmitted to the memory card and the rights object in the memory card is removed (deleted). After transmitting the removal request, second state information is generated and held in the content player to indicate that the removal of the rights object in the memory card has not yet been completed and that the rights object installed in the content player is conditionally enabled. When the memory card receives the removal request, the memory card removes the rights object from the memory card and transmits a removal response for notifying completion of the removal to the content player.
