Patent number: 8000503Abstract: A biometrics authentication system utilizes information of the palm of the hand of a body to perform individual authentication. A processing unit obtains an image of the palm of the hand of the same body a plurality of times from an image capture unit, judges the degrees of similarity among the characteristic data sets of the plurality of images of the palm of the hand, and registers a plurality of characteristic data sets with a high degree of similarity in a storage unit. And the shape of the hand in the image is checked from the outlines in the image of the palm of the hand, so it is possible to rapidly judge whether image capture has been successful and extract characteristic data, and registration processing can be executed in a short length of time.Type: GrantFiled: March 18, 2005Date of Patent: August 16, 2011Assignees: Fujitsu Limited, Fujitsu Frontech LimitedInventors: Hideo Kamata, Takumi Kishino, Shinichi Eguchi

Patent number: 7725733Abstract: A biometrics authentication device uses biometrics information to perform individual authentication. Primary and secondary verification of biometrics characteristic data from an image capture device are performed by a control unit and IC card. The biometrics character data is scrambled and transmitted between devices. The second registration data which is more important to authentication is stored within the IC card, and first registration data is registered in the IC card in a scrambled state. Security is improved, and moreover the load on the CPU of the IC chip in the IC card is reduced.Type: GrantFiled: February 24, 2005Date of Patent: May 25, 2010Assignees: Fujitsu Limited, Fujitsu Frontech LimitedInventors: Yasuyuki Higashiura, Takumi Kishino, Shinichi Eguchi, Masaki Watanabe, Toshio Endoh, Yutaka Katsumata

Patent number: 7660992Abstract: An electronic data storage system stores electronic data with attaching an electronic signature, and output the electronic data along with the attached electronic signature, which decreases the operation costs with a simple operation. By using a public key-based signature, a third party can verify the data, and by using a secret check code, the electronic signature at registration is always valid without risk of falsification. Also by attaching an electronic signature at access, the validity of the stored data is assured, and a third party can verify the data. By using all of these features, the verification by a third party becomes possible over the long term. In this way the long term storage of electronic data is implemented.Type: GrantFiled: January 30, 2004Date of Patent: February 9, 2010Assignees: Fujitsu Limited, Fujitsu Frontech LimitedInventors: Yasuyuki Higashiura, Takumi Kishino, Keizo Sato, Shoki Kadowaki, Seigo Kotani

Patent number: 7469263Abstract: A content management system manages an original of electronic data content and is capable of handling increases in the volume of electronic data and maintains uniqueness of the original. Serial content management or processing history is managed by an original management device, and content data alone is archived on portable media with media IDs. Therefore, increases in the volume of electronic data can be easily handled, a history of updates to the original can be managed by the system, and uniqueness of the original can be confirmed by the media IDs because the medium-specific media IDs are treated as original data.Type: GrantFiled: June 26, 2003Date of Patent: December 23, 2008Assignees: Fujitsu Limited, Fujitsu Frontech LimitedInventors: Yasuyuki Higashiura, Takumi Kishino
