Patent number: 7272717Abstract: Each embodiment of this invention implements step-by-step and empirical authentication of devices upon digital authentication among a plurality of devices. Each of a plurality of authentication devices of each embodiment can unidirectionally generate a hash value of a low experience rank from a hash value of a high experience rank, and receives a set of high experience rank and hash value in accordance with an experience. Upon receiving a certification request of the experience rank from another authentication device, the authentication device transmits a corresponding hash value to the authentication device as a request source. Upon sending a certification request of an experience rank to another authentication device, the authentication device verifies a hash value obtained from the other authentication device on the basis of a self hash value. In this way, the authentication devices authenticate each other's experience ranks.Type: GrantFiled: February 27, 2003Date of Patent: September 18, 2007Assignee: Kabushiki Kaisha ToshibaInventors: Shingo Miyazaki, Naoki Endo, Takehisa Kato, Daigo Yoshii, Koichi Noguchi, Hideo Shimizu, Toru Kambayashi, Yasuhiko Suzuki, Akio Okazaki, Kenichi Hiramatsu, Sunao Wada, Koji Mikami, Akira Toshima, Masao Suga, Akihiro Kasahara

Patent number: 6882741Abstract: A first illumination section radiates light at a certain degree of illuminance toward the face of a human recognition object from an upper right part or an upper left part of a camera, and a second illumination section radiates light at a certain degree of illuminance toward the face of the human recognition object from a lower part of a camera. The camera photographs and inputs a facial image of the human recognition object. The image processing section extracts a feature value of the face of the human recognition object from a facial image inputted by the camera and collates the feature value extracted with a standard feature value registered in advance so as to recognize a facial image of the human recognition object.Type: GrantFiled: March 22, 2001Date of Patent: April 19, 2005Assignee: Kabushiki Kaisha ToshibaInventors: Hironori Dobashi, Toshio Hirasawa, Akio Okazaki, Toshio Sato, Hiroshi Sukegawa
