Patent number: 8341703Abstract: In remotely coupling one terminal apparatus to a server apparatus, if an authentication processing of a user of one terminal apparatus has been already completed, the user can switch one terminal apparatus to another without an additional authentication processing. Authenticated information indicating that the authentication of the user has already been successfully completed is transferred to another terminal apparatus by coordinating the authenticated information between more than one terminal apparatuses. Another terminal apparatus receives a service from the server apparatus using the authenticated information. Upon coordinating the authenticated information among more than one terminal apparatuses, another terminal apparatus to receive the authenticated information may be authenticated. A storage medium which conducts the authentication may be coupled to a terminal apparatus to be authenticated.Type: GrantFiled: August 12, 2009Date of Patent: December 25, 2012Assignee: Hitachi, Ltd.Inventors: Katsuyuki Umezawa, Akira Kanehira, Katsuya Terada, Yoshiaki Yamaguchi

Patent number: 7996911Abstract: In order to protect the user security data, provided is a memory card capable of preventing the data leakage to a third party not having the access authority by imposing the limitation on the number of password authentications and automatically erasing the data. In a system comprised of a multimedia card and a host machine electrically connected to the multimedia card and controlling the operations of the multimedia card, a retry counter for storing the number of password authentication failures is provided and the upper limit of the number of failures is registered in a register. When passwords are repeatedly entered once, twice, . . . and n times and the retry counter which counts the entries reaches the upper limit of the number of failures, the data is automatically erased so as not to leave the data in the flash memory.Type: GrantFiled: July 29, 2008Date of Patent: August 9, 2011Assignee: Renesas Electronics CorporationInventors: Satoshi Yoshida, Kunihiro Katayama, Akira Kanehira, Masaharu Ukeda

Publication number: 20100261452Abstract: A coupling authentication of a mobile phone terminal is performed between the mobile phone terminal and an authentication server. Both the mobile phone terminal and an authentication server store therein coupling authentication information. In performing an authentication at a service device, the mobile phone terminal generates service authentication information using coupling authentication information and transmits the generated service authentication information to the authentication server. The authentication server performs the authentication using the coupling authentication information and the service authentication information and transmits a result of a service authentication to the service device. The service device determines whether or not the service authentication has been successfully completed, based on the service authentication result.Type: ApplicationFiled: February 16, 2010Publication date: October 14, 2010Inventors: Katsuyuki UMEZAWA, Akira Kanehira, Kenya Nishiki
