Abstract: An information output system for tampering detection 100, including: a digital image acquiring unit 15 for acquiring a digital image including target information for tampering detection as an image; an encrypting unit 11 for converting the digital image based on an encryption key to generate an encrypted image; and an output unit 18 for outputting the encrypted image generated by the encrypting unit 11 so that the encrypted image is recorded on a paper medium on which the image of the target information is to be recorded or on which the image of the target information is recorded.

Abstract: An electronic document processing system 900 includes a digital image generating unit 15 generating a digital image in a predetermined range of the electronic document; an image encrypting unit 11 generating an encrypted image by converting at least a partial area of the generated digital image; a data encrypting unit 21 generating encrypted data by extracting data contained in the predetermined range in pieces of data organizing the electronic document and encrypting the data; an encrypted data storing unit 22 storing the encrypted data; and an encrypted electronic document generating unit 23 generating an encrypted electronic document by replacing the data contained in the predetermined range in the electronic document with the encrypted image.

Abstract: 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 unit 21 accepting an input of rendering information for depicting a content of electronic data; a digital image generating unit 15 generating a digital image defined on the basis of the accepted rendering information; a definition information acquiring unit 23 acquiring 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 unit 11 generating an encrypted image by converting the image of the partial area on the basis of the key information; and an output unit 12 outputting the encrypted image.

Abstract: An image reading apparatus includes an image reading unit, a touch panel, a storage unit, and a control unit, wherein the storage unit includes a storage-location-information storage unit that stores storage location information related to a storage location of an image file of a document read by the image reading unit, and the control unit includes an image displaying unit that displays a storage location icon representing the storage location and an image display area showing the image file, a display mode changing unit that changes, when an image selection instruction to select the image file is input, a display mode of the image display area so that the storage location icon can be viewed, and a storing unit that stores, when an icon selection instruction to select the storage location icon is input, the image file in the storage location corresponding to the storage location icon.
