Patent number: 7254711Abstract: A certificate authority for certifying the validity of the collation result from a user terminal is placed on a communication network. The user terminal identifies a user himself or herself by collation by using biometrical information of the user. In response to notification of the collation result from the user terminal across the communication network, a service providing apparatus requests across the communication network the certificate authority to certify the validity of the collation result. When a certificate which certifies the validity of the collation result is notified from the certificate authority across the communication network, the service providing apparatus provides a predetermined service to the user.Type: GrantFiled: April 4, 2002Date of Patent: August 7, 2007Assignee: Nippon Telegraph and Telephone CorporationInventors: Satoshi Shigematsu, Mamoru Nakanishi, Hiroki Suto

Patent number: 6990219Abstract: An image capturing apparatus includes an image capturing section and capture control section. The image capturing section converts the shape of an object into an electrical quantity in accordance with the parameter value set in a parameter setting section, and outputs image data representing an image corresponding to the shape of the object. The capture control section receives the image data output from the image capturing section, calculates an evaluation index for evaluating the image quality of the image from the image data. If the evaluation index falls outside the range of a preset reference value, the capture control section changes the parameter value set in the parameter setting section so as to make the evaluation index fall within the range of the reference value to output the image data which is received from the image capturing section and the evaluation index of which falls within the range of the reference value.Type: GrantFiled: December 12, 2001Date of Patent: January 24, 2006Assignee: Nippon Telegraph and Telephone CorporationInventors: Hiroki Morimura, Toshishige Shimamura, Kenichi Saito, Yukio Okazaki, Hakaru Kyuragi, Chikara Yamaguchi, Hiroki Suto, Satoshi Shigematsu

Publication number: 20030048173Abstract: An authentication method includes the first, second, and third steps. In the first step, a biometrical information sensor reads the biometrical information of a user. In the second step, the read biometrical information is collated with registered biometrical information in a registration memory. When the collation result represents that collation has successfully been done, user unique information from an authentication information output section is converted into an emulator signal corresponding to a service provided by a use device. The emulator signal is transmitted to the use device. In the third step, the use device provides the service to the user on the basis of the received emulator signal. An authentication system and authentication token are also disclosed.Type: ApplicationFiled: September 5, 2002Publication date: March 13, 2003Inventors: Satoshi Shigematsu, Takahiro Hatano, Hiroki Suto, Yukio Okazaki, Hakaru Kyuragi
