An electronic document encrypting system, for accomplishing an object of providing a system capable of distributing an electronic document containing important information with a browsing restriction being set and information with none of the browsing restriction being set without removing the important information, includes: an encryption area extracting unitextracting an encryption target area from an electronic document; a digital image generating unit generating a digital image on the basis of the area extracted by the encryption area extracting unit in the electronic document; an encrypting unitencrypting the digital image generated by the digital image generating uniton the basis of an encryption key; and an encrypted electronic document generating unitgenerating an encrypted electronic document in which when the electronic document is output, in place of the extracted information, an encrypted image encrypted by the encrypting unitis output to an area to which the information extracted by the encryption area extracting unitis to be output.

Electronic document encrypting system, decrypting system, program and method

Configuring a paper medium information encrypting system to include a digital image acquiring unit acquiring a digital image of information by capturing an image of a paper medium, an encryption area designating unit designating an encryption target partial area in the digital image, an image converting unit converting the image of the partial area into a processed image on the basis of an encryption key, a pixel value converting unit generating a converted image having a regularity at a spaced interval, used for specifying a position of the partial area when performing decryption, by regularly converting pixel values of the processed image, and an output unit outputting an encrypted image containing the converted image, wherein the encryption area designating unit designates, as the encryption target partial area, an area specified by an area designating information for specifying the area on the digital image.

Paper medium information encrypting system, decrypting system, program and method

Provided is an image processing system capable of simply executing image processing for encryption and decryption without causing a user to perform a time-consuming operation of generating a processing target image, the system including: a rendering information input accepting unitaccepting an input of rendering information for depicting a content of electronic data; a digital image generating unitgenerating a digital image defined on the basis of the accepted rendering information; a definition information acquiring unitacquiring definition information containing area designating information for specifying an encrypting target partial area in the generated digital image and key information used on the occasion of encrypting the partial area; an encrypting unitgenerating an encrypted image by converting the image of the partial area on the basis of the key information; and an output unitoutputting the encrypted image.

Image processing system, program and method

A read-image transfer apparatus is connected to an image reader and to a weblog server via a network. The read-image transfer apparatus stores therein user setting information including at least destination address information for the weblog server, a transfer protocol for the weblog server, and user identification information for causing the weblog server to identify a user. The read-image transfer apparatus controls the image reader so as to read image information from a document, stores the read image information in a memory, and transfers the stored image information to the weblog server based on the stored user setting information.
