  • Patent number: 8045194
    Abstract: A document management system capable of reliably implementing disposal management of printed matter resulting from print output based on document data. A print history of images based on the document data printed by a printing device is managed. A deletion instruction for at least one set of document data stored in a document storage device is received. The document data targeted for deletion from the document storage device based on the deletion instruction is deleted. Management information of the document data targeted for deletion from the document storage device based on the print history managed by the management unit is deleted.

  • Patent number: 7764404
    Abstract: When an image including a specific image is created and stored, it is determined whether or not the height/width ratio of the specific image has been changed by a user in the image that includes the specific image. Whether or not to store the image including the specific image is controlled based on the results of the determination.

  • Patent number: 7586641
    Abstract: 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.

  • Patent number: 7546244
    Abstract: 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.

  • Publication number: 20050193200
    Abstract: 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.

  • Patent number: 5937427
    Abstract: 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.
