  • Patent number: 8094946
    Abstract: The present invention provides an image processing system, which can reduce calculation time by alleviating a calculation load in assessing the occurrence of tampering of an image. For example, the image processing system of the present invention first identifies a type of a form of an image to be assessed in assessing the occurrence of tampering. Next, a characteristic amount of a certain region (flexible region) corresponding to the identified type of a form is extracted as a characteristic amount of the image to be assessed. Then, the extracted characteristic amount of image to be assessed and the characteristic amount extracted from a certain region in an original image are compared and the compared result is notified as the assessment result. A flexible region, to which a user writes, is preferably specified as said certain region.

  • Patent number: 7771133
    Abstract: An apparatus being connectable to a printing apparatus and an information processing apparatus, comprising, a reception unit adapted to receive identification information used to identify the printing apparatus and used to specify a printer driver in the information processing apparatus, from the printing apparatus after connection to the printing apparatus, a storage unit adapted to store the identification information received by said reception unit, a transmission unit adapted to transmit the identification information stored in said storage unit to the information processing apparatus after connection to the information processing apparatus, a second reception unit adapted to receive print data generated in the information processing apparatus using a printer driver specified based on the identification information, from that information processing apparatus, and a second transmission unit adapted to transmit the print data received by said reception unit to the printing apparatus.

  • Patent number: 7684077
    Abstract: An image processing method includes steps of acquiring information about image conditions, such as resolution settings, supported by a first print device for printing image data; generating an image data item corresponding to each acquired image condition; determining an image attribute, such as a character image or a dot image, included in each of the generated image data items; trimming an image in an area including the image attribute from each of the image data items; laying out the trimmed images on prepared template data; and printing out the template data using a second print device different from the first print device.

  • 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.
