Patent number: 8332640Abstract: A user can watch desired content among a plurality of encrypted contents recorded in a storage apparatus having a large capacity recording medium when the user wants to watch. Usage Pass (UP) necessary for watching content and encrypted content are recorded in a rental storage apparatus. The UP is in an invalid state when the storage apparatus is rented, and processing for validating the corresponding UP is executed between the storage apparatus and a host apparatus through which content is watched to thereby make content watchable. A history that processing for validating the UP is executed is recorded in the storage apparatus. A service provider bills a content use fee to the user based on the history of the storage apparatus.Type: GrantFiled: December 10, 2008Date of Patent: December 11, 2012Assignee: Hitachi, Ltd.Inventors: Haruko Takano, Yukihide Inagaki, Tatsuya Hirai

Patent number: 7953098Abstract: The invention flexibly limits a terminal able to play content and prevents unfair utilization of the content. In one embodiment, an identifier proper to each terminal device is allocated to discriminate each playback equipment. The identifier of a terminal which is allowed to play the content is registered to this license. When the content is played, authentication is performed between the terminal device as a license transfer destination and a memory device as a license transfer source. The identifier of the terminal device itself is transmitted to the memory device as a transfer source at an authenticating time. The memory device collates the identifier sent from the terminal device with an identifier registered to the license. If these identifiers are the same identifier, the memory device transfers the license to the terminal device. In contrast to this, if these identifiers are different identifiers, the memory device stops the transfer of the license.Type: GrantFiled: June 14, 2006Date of Patent: May 31, 2011Assignee: Hitachi Global Storage Technologies, Netherlands B.V.Inventors: Haruko Takano, Tatsuya Hirai
