Patent number: 8559428Abstract: MTID of a terminal apparatus is preliminarily registered into a database of an ISP. In step S2, when a power source of the terminal apparatus is turned on first, (MTID=B) is transmitted from the terminal apparatus to a router. A transmission signal is received by the router and (HGWID=A, MTID=B) is transmitted from the router to the ISP. If (HGWID=A, MTID=B) has been registered in the database, the ISP transmits a permission message in step S5. In step S6, an IP address for a new terminal apparatus is allocated and the new terminal apparatus can participate in a homenetwork. If (HGWID=A, MTID=B) is not registered, a refusal message is sent to the router.Type: GrantFiled: January 2, 2009Date of Patent: October 15, 2013Assignee: Sony CorporationInventors: Shinya Kimura, Takahiro Sasaki, Motoki Nakade, Yoshiyuki Kunito, Akihiro Hokimoto, Makoto Oka, Shinako Matsuyama, Atsushi Shionozaki

Patent number: 8538887Abstract: In a content delivery system, delivery of content and charging the fee of the content are performed and managed in a highly secure and effective fashion. If a content-purchasing request is transmitted from a user device to a shop server, a charging process is performed. A user device authentication server, which manages content delivery, converts an encrypted content key KpDAS(Kc) encrypted using a public key of the user device authentication server (DAS) into an encrypted content key KpDEV(Kc) encrypted using a public key KpDEV of the user device. If the charging process is successfully completed, the shop server transmits, to the user device, the encrypted content key KpDEV(Kc).Type: GrantFiled: October 31, 2001Date of Patent: September 17, 2013Assignee: Sony Computer Entertainment Inc.Inventors: Kenji Yoshino, Yoshihito Ishibashi, Toru Akishita, Taizo Shirai, Makoto Oka, Masaharu Yoshimori

Patent number: 7496756Abstract: A system in which content usage conditions can be upgraded without the need for a service provider to control content-usage rights of a user. In the system in which encrypted content is distributed and is allowed to be utilized only by authorized users, the service provider receives a content usage-right certificate from the user, and on the condition that it is determined that data is not tampered with by verifying a digital signature of an issuing entity of the content usage-right certificate, the service provider obtains user information and content purchase information of the user from the content usage-right certificate, and performs upgrade processing by, for example, changing the usage conditions. It is thus possible to change the content usage conditions without the need for the service provider to possess usage control data.Type: GrantFiled: August 15, 2002Date of Patent: February 24, 2009Assignee: Sony CorporationInventors: Makoto Oka, Yoshihito Ishibashi, Hiroshi Abe, Noboru Shimada, Masahiko Enari, Kenji Yoshino

Publication number: 20040039906Abstract: A system and method for performing reliable access limitation in communication via a network are realized. In communication among communication processing devices via a communication network, a relay server such as a home server verifies and examines an attribute certificate of the access source, and determines whether or not the access source is a permitted member of the access destination. Only when the access source is permitted by the access destination, a name resolution process is performed, and the address information of the access destination is notified to the access source. A group attribute certificate in which the domain name and the host name of the access source are described is used, and the address corresponding to the domain name and the host name is updated.Type: ApplicationFiled: June 5, 2003Publication date: February 26, 2004Inventors: Makoto Oka, Noboru Shimada, Takayoshi Kawaguchi, Madoka Masugi, Yoshihito Ishibashi, Hiroshi Abe, Nobutaka Toyoshima
