Patent number: 11443068Abstract: The invention prevents data from leaking. In a data management system (1), a terminal device (2) saves a remaining data among the remaining data and an incomplete data acquired by partitioning an image data of an ID card of a user in a storage unit, and uploads the incomplete data to a data management server (5) via a network (N). A data recovery device (4) acquires the remaining data from the terminal device (2), and acquires the incomplete data from the data management server (5) via the network (N). Further, the data recovery device (4) recovers the image data of the ID card of the user from the remaining data and the incomplete data.Type: GrantFiled: November 15, 2021Date of Patent: September 13, 2022Assignees: SATORI ELECTRIC CO., LTD., A⋅T COMMUNICATIONS CO., LTD.Inventors: Takafumi Kakioka, Hiroshi Toyoizumi, Youichi Azuma

Patent number: 10102463Abstract: In a two-dimensional code generation device (100), a white point determiner (111) determines a white point in an environment to output a two-dimensional code. A threshold acquirer (112) acquires a threshold of lightness used by a reading device for reading multiple cells in binary, the threshold being represented in a device-independent color space that is based on the white point determined by the white point determiner (111). A two-dimensional code generator (113) generates a two-dimensional code expressing information by a distribution pattern of multiple cell dots formed by coloring the multiple cells in a color of lightness equal to or higher than the threshold acquired by the threshold acquirer (112) and in a color of lightness lower than the threshold.Type: GrantFiled: January 13, 2015Date of Patent: October 16, 2018Assignee: A.T Communications Co., Ltd.Inventors: Hiroshi Toyoizumi, Youichi Azuma, Toshiki Nishiyama, Takuji Tokiwa

Publication number: 20180145962Abstract: A server device for safely managing information is configured to store prescribed character codes and converted character codes in correlation with each other, said server device being connected, via a network (N), to a terminal device for receiving a converted character code string corresponding to a character string indicating personal information stored in a storage unit device. Responsive to the reception of a prescribed character code string corresponding to a character string indicating an item included in the personal information by the terminal device, the server device converts each of prescribed character codes included in the prescribed character code string to a corresponding converted character code, thereby generating a converted character code string corresponding to the character string indicating the item.Type: ApplicationFiled: July 21, 2015Publication date: May 24, 2018Applicant: A.T COMMUNICATIONS CO., LTD.Inventors: Hiroshi TOYOIZUMI, Youichi AZUMA, Tetsuya TAKAHASHI, Maya TAKAMI

Patent number: 9654291Abstract: In an authentication system, a mobile communication client transmits to an authentication server a bit signal that includes an image capture bit sequence obtained by capturing an image of a self-aware two-dimensional code having authentication information embedded in a correction area, and a number bit sequence that indicates a serial number of an authentication application program being stored in storage. The authentication server authenticates the user of the mobile communication client and the self-aware two-dimensional code. Subsequently, the authentication server transmits designated information expressed by the self-aware two-dimensional code to the mobile communication client, on the condition that the user and the self-aware two-dimensional code are successfully authenticated. Consequently, the mobile communication client is able to acquire the designated information expressed by the self-aware two-dimensional code.Type: GrantFiled: July 3, 2013Date of Patent: May 16, 2017Assignee: A.T Communications Co., Ltd.Inventors: Hiroshi Toyoizumi, Youichi Azuma

Patent number: 9547815Abstract: A logo-added two-dimensional code creation device determines the color of a two-dimensional code to be superimposed on a logo image by adjusting the L value indicating the color lightness, whereby a logo-added two-dimensional code readable regardless of influence of post-printing processing and/or ambient light can be created. The logo-added two-dimensional code has smaller cells superimposed on the tiger character that can easily lose the design integrity than the cells superimposed on the background part, ensuring the design integrity of the logo image without impairing the readability of information.Type: GrantFiled: November 3, 2015Date of Patent: January 17, 2017Assignee: A.

Patent number: 9436852Abstract: A two-dimensional code authenticating device reads a self-authentication two-dimensional code to obtain an RS bit string, and detects a bit string c? as an error using the RS bit string. Next, an exclusive OR between a bit string l included in the RS bit string and the bit string c? detected as an error is calculated to obtain a bit string c?, and a bit string md is obtained by decrypting the bit string c? through a scheme corresponding to the encryption. Subsequently, it is determined whether or not the decrypted bit string md matches the bit string m included in the RS bit string, thereby authenticating the self-authentication two-dimensional code.Type: GrantFiled: August 17, 2012Date of Patent: September 6, 2016Assignee: A.T.

Patent number: 8860699Abstract: A two-dimensional code display system has a display unit which can display a two-dimensional code representing predetermined information by plural cells arrange in a matrix, and a control unit which changes the display form of the two-dimensional code. For example, after 0.5 second has elapsed since the display unit starts displaying the image of a logo mark, the control unit controls the display unit to change the display from the image of the logo mark to a two-dimensional code. After 2.0 seconds has elapsed since the display unit starts displaying the two-dimensional code, the control unit controls the display unit to change the display from the two-dimensional code to the image of the logo mark. By repeating such control, the control unit can control the display unit to display alternately the image of the logo mark and the two-dimensional code.Type: GrantFiled: October 29, 2008Date of Patent: October 14, 2014Assignee: A.

Patent number: 8498443Abstract: The present invention provides a watermark information embedding device, a watermark information processing system, a watermark information embedding method and program that can provide a two-dimensional code enabling detection of copying. The watermark information embedding device comprises a first wavelet transform unit (12), a watermark information embedding unit (14) and an inverse wavelet transform unit (150). The first wavelet transform unit (12) performs a discrete wavelet transform on an original image of a two-dimensional code and decomposes this into various frequency components, namely an LL component, an LH component, an HL component and an HH component. The watermark information embedding unit (14) embeds the watermark information in the HH component as a high-frequency component in an oblique direction.Type: GrantFiled: June 2, 2010Date of Patent: July 30, 2013Assignees: Kagoshima University, A.T Communications Co., Ltd.Inventors: Satoshi Ono, Shigeru Nakayama, Makoto Tsutsumi
