Patent number: 7586641Abstract: A data processing method, which is provided in an image processing system in which a server and a data processor communicate with each other to perform a predetermined data process, includes a step of extracting a feature amount of electronic data to be output from a printer, a step of transmitting original specifying information including the extracted feature amount and a user ID for discriminating a print requester of the electronic data, to the server, a step of controlling generation of print data to be output to the printer, based on original certification information notified by the server, and a step of causing the printer to print the generated print data and information indicating that the print data corresponds to an original. By this method, a large storage capacity is not required to certify one data, and to keep a secret of the stored electronic data is easy.Type: GrantFiled: February 10, 2004Date of Patent: September 8, 2009Assignee: Canon Kabushiki KaishaInventors: Yoichi Takaragi, Kenichi Takahashi, Tatsuo Shinagawa, Akihiro Matsuya, Kunio Yoshihara

Patent number: 7546244Abstract: Since an image processing system that can authenticate the originality of digital data adopts an arrangement that does not save and manage digital data in a server, the server scale can be prevented from increasing, and the security can be improved. To this end, in this invention, in an image processing system in which a client and server are connected to be able to communicate with each other, the feature amount and user ID of digital data to be registered are registered in the server, and the digital data is saved in the client in correspondence with the registration number and registration date upon registering the feature amount and user ID.Type: GrantFiled: December 1, 2004Date of Patent: June 9, 2009Assignee: Canon Kabushiki KaishaInventors: Kunio Yoshihara, Yoichi Takaragi, Akihiro Matsuya, Tatsuo Shinagawa

Image processing apparatus and method, storage medium storing computer-readable program, and program
Publication number: 20050193200Abstract: An image processing apparatus extracts feature information from electronic data to be transmitted to an output device, and encrypts the electronic data before transmitting it to the output device. The image processing apparatus manages an output time and date at which the transmitted electronic data is to be printed, and transmits a decryption key for decrypting the transmitted encrypted electronic data to the output device at the output time and date. A hash value extracted from the electronic data decrypted by the output device is checked against a hash value extracted by the image processing apparatus. When these hash values are consistent with each other, the image processing apparatus instructs printing of the electronic data decrypted by the output device.Type: ApplicationFiled: February 24, 2005Publication date: September 1, 2005Applicant: Canon Kabushiki KaishaInventors: Rieko Akiba, Etsuko Maeda, Tatsuo Shinagawa, Shuji Someya -

Patent number: 5937427Abstract: In recording of information, upon reception of a write request from a host computer, recording information from the host computer is stored in a cache memory, and thereafter, a notification of write completion is transferred to the host computer to accept the next request. A request from the host computer is compared with a most recent prior request so as to judge if two requests are sequential write accesses. When it is determined that the two requests are sequential write accesses, a write operation corresponding to the next write access is sequentially performed after a write operation corresponding to the most recent prior request.Type: GrantFiled: July 14, 1997Date of Patent: August 10, 1999Assignee: Canon Kabushiki KaishaInventors: Tatsuo Shinagawa, Yutaka Ogasawara
