Patent number: 8514240Abstract: A processing unit executes a process for creating a dedicated color palette (color palette dedicated for a palm vein GUI) as an initialization process, and creates the color palette dedicated for a palm vein GUI. The processing unit replaces a 256-level gradation grayscale palette set in an acquired photographed image with the color palette dedicated for the palm vein GUI. The processing unit performs guide GUI display for guiding a palm to an appropriate position, using a display image formed by setting the color palette dedicated for the palm vein GUI for the photographed image acquired from a photographed image-acquiring process.Type: GrantFiled: August 7, 2012Date of Patent: August 20, 2013Assignee: Fujitsu Frontech LimitedInventors: Naoko Suzuki, Junichiro Toya, Shinya Iwasaki, Yasuhiko Mita, Kiyomi Ozawa

Patent number: 8423786Abstract: A biometrics authentication device which detects body characteristics, performs verification against registered biometrics data, and performs individual authentication, by which confidentiality is improved even when biometrics data is separated, distributed and stored. A biometrics information key is created from biometrics data detected by a detection device, the biometrics data is divided into a plurality of portions, and the portions are stored on different media. The biometrics information key is stored on one media, and at the time of authentication, the separated biometrics data portions are combined and a biometrics information key is created and is compared with the biometrics information key, to judge the linked relationship. Hence confidentiality of the association of the individual separated data portions can be improved even when the biometrics data is separated, distributed and stored, contributing to prevent illicit use resulting from leakage or theft of biometrics data.Type: GrantFiled: September 11, 2007Date of Patent: April 16, 2013Assignees: Fujitsu Limited, Fujitsu Frontech LimitedInventors: Kazuo Takaku, Yasuhiko Mita, Naoko Suzuki, Shinya Iwasaki, Masayuki Yano, Ikuo Mutou

Patent number: 8184866Abstract: A biometrics authentication device identifies characteristics of the body from captured images of the body and performs individual authentication. The device guides a user, at the time of verification, to the image capture state at the time of registration of biometrics characteristic data. At the time of registration of biometrics characteristic data, body image capture state data is extracted from an image captured by an image capture unit and is registered in a storage unit, and at the time of verification the registered image capture state data is read from the storage unit and is compared with image capture state data extracted at the time of verification, and guidance of the body is provided. Alternatively, an outline of the body at the time of registration, taken from image capture state data at the time of registration, is displayed.Type: GrantFiled: September 13, 2007Date of Patent: May 22, 2012Assignees: Fujitsu Limited, Fujitsu Frontech LimitedInventors: Kazuo Takaku, Yasuhiko Mita, Naoko Suzuki, Shinya Iwasaki, Masayuki Yano

Patent number: 7885433Abstract: A biometrics authentication system detect body characteristics, verify the characteristics against registered biometrics data to perform individual authentication. In 1:n authentication, a plurality of different type biometrics database sets of a user are registered in a database, and at the time of verification of one type biometrics data set with one type registered biometrics data set, the control unit judges whether similar biometrics data sets of other person are registered, and if other person's similar biometrics data sets are registered, performs verification of each of the another type biometrics data sets of the plurality of similar biometrics data sets with the detected another type biometrics data set, and identifies the individual in question.Type: GrantFiled: January 31, 2007Date of Patent: February 8, 2011Assignees: Fujitsu Limited, Fujitsu Frontech LimitedInventors: Masayuki Yano, Yasuhiko Mita, Naoko Suzuki, Shinya Iwasaki, Kazuo Takaku, Ikuo Mutou, Yutaka Katsumata

Patent number: 7697730Abstract: In a biometrics authentication device which uses biometrics information to authenticate individuals, guidance is provided such that image capture of biometrics information is performed appropriately. An image capture device is caused to perform a plurality of image capture operations (including distance measurement) at short intervals. And when image capture NG occurs frequently, a control unit stacks the NG results, and if image capture NGs are not resolved even after a prescribed number of image capture operations, judges that the relation between the body part and the image capture device must be corrected, analyzes the stacked image capture NG causes, and displays a guidance screen on a display device according to the analysis result.Type: GrantFiled: March 10, 2005Date of Patent: April 13, 2010Assignees: Fujitsu Limited, Fujitsu Frontech LimitedInventors: Sagiri Okamura, Kiyotaka Awatsu, Yasuhiko Mita, Takahiro Kudo
