Publication number: 20120254935Abstract: An authentication collaboration server of an authentication collaboration system performs a secrecy calculation process using authentication information as input for an authentication process, generating secret authentication information for each piece of the authentication information. An authentication information verification server obtains and compares sets of the combination of secret authentication information generated by the authentication server, and a user ID identifying a user of a user terminal using the authentication information that is a source of the secret authentication information. The authentication information verification server extracts the plurality of pieces of authentication information that have been applied.Type: ApplicationFiled: January 26, 2012Publication date: October 4, 2012Applicant: HITACHI, LTD.Inventors: Akifumi YATO, Tadashi KAJI, Naoki HAYASHI, Shinichi IRUBE

Publication number: 20120198039Abstract: A processing load on service is distributed to improve the availability of linkage service even if the details of the processing of the linkage service are unknown. A service dynamic linkage device (110) sequentially selects pieces of web service which can be executed on the basis of dependence relationship information having identified a web server which should have already been executed among pieces of web service included in a scenario, the execution of which has been requested from a user-side communication terminal (140), and repeatedly performs processing to be executed until there are no pieces of web service included in the scenario.Type: ApplicationFiled: February 15, 2010Publication date: August 2, 2012Applicant: Hitachi, Ltd.Inventors: Naoki Hayashi, Tadashi Kaji, Akifumi Yato, Dan Yamamoto, Shinichi Irube

Publication number: 20120005362Abstract: A streaming data delivery system contrived to curtail the procedure until a session is established between a delivery server and a user terminal includes a delivery device, a server for provisional coupling, format conversion servers, a terminal, and a 3PCC device which implements Third Party Call Control. The 3PCC device obtains format information from the terminal and establishes a session between the terminal and the server for provisional coupling; also obtains data format information from the data delivery device and establishes a session between the delivery device and the server for provisional coupling; further selects a format conversion server, transfers the session between the delivery device and the server for provisional coupling into a session between the delivery device and the selected format conversion server, and transfers the session between the terminal and the server for provisional coupling into a session between the terminal and the selected format conversion server.Type: ApplicationFiled: March 24, 2011Publication date: January 5, 2012Inventors: NAOKI HAYASHI, Tadashi Kaji, Dan Yamamoto, Shinichi Irube

Data communication system enabling data communication between communication devices through a server
Patent number: 7940780Abstract: A method and a system for speeding up session establishment are provided, wherein the time required to establish a session is reduced, even in the case where a session management server requires a large amount of time to process respective functions required for establishing the session (such as making a decision regarding whether to permit or deny provision of a service, or generating a session key). The session management server is provided with means for conducting, in parallel, processing to issue processing requests for respective functions required for establishing a session (such as making a decision regarding whether to permit or deny provision of a service, or generating a session key) and processing to forward a communication message transmitted by a communications device or another session management server attempting to establish a session.Type: GrantFiled: September 5, 2008Date of Patent: May 10, 2011Assignee: Hitachi, Ltd.Inventors: Dan Yamamoto, Tadashi Kaji, Akifumi Yato, Takahiro Fujishiro, Shinichi Irube -
Publication number: 20100138899Abstract: An authentication server is dynamically changed in consideration of a user's situation, a kind of service used by the user and user's convenience. When a terminal device 1 is going to receive provision of service from a service providing server 2, an authentication intermediary server 4 selects an authentication server 3 among authentication servers 3 that satisfy selection conditions previously set by the user of the terminal device 1 such as presence information, priority, usage condition, service providing server conditions and the like, so that the user of the terminal device 1 undergo authentication by the selected authentication server 3.Type: ApplicationFiled: November 24, 2009Publication date: June 3, 2010Inventors: Dan YAMAMOTO, Tadashi Kaji, Takahiro Fujishiro, Shinichi Irube

Publication number: 20090327394Abstract: Technology is provided for easily converting data for use with a plurality of receiving devices. The structure-specific message generator of an information providing server generates reference information by converting the data structure of information received from a transmitting device into a data structure processable by a plurality of receiving devices. A SOAP notification generator then generates notification information for each of the receiving device by replacing information at predetermined parts in the generated reference information with receiving device-specific information.Type: ApplicationFiled: February 24, 2009Publication date: December 31, 2009Inventors: Tadashi KAJI, Dan Yamamoto, Takahiro Fujishiro, Shinichi Irube, Fumihiko Inoda, Akio Ito
