    摘要: When creating a marker, an encryption apparatus extracts each pixel value in a region and allows a storing unit to save, as restoration information, the high-order bits of each extracted pixel value. Then, the encryption apparatus creates a marker by changing the high-order bits of the pixel value in a region in which the marker is created and embeds encrypted information in an encrypted region specified by the marker. When decoding the encrypted information, a decoding apparatus detects the marker from a digital image, decodes the encrypted information in the encrypted region specified by the marker, and overwrites bits contained in the restoration information with the high-order bits of the pixel value of the marker.

    摘要: An encrypting device encrypts original document data by use of a password of an addressee, thereby generating encrypted document data. A decryption authority changing device, of which operating authority is held by the addressee, generates authority changing information M structured by encrypting the password of the addressee with a password of a proxy, and notifies a decrypting device of the information, of which the operating authority is held by the proxy. The decrypting device decrypts the password of the addressee by employing the password of the proxy, and decrypts the encrypted document data by use of the decrypted password of the addressee.

    摘要: An image processing system includes: an image input unit which reads an image printed on a medium and generates electronic data representing the image; and a processing unit which corrects the image represented by the electronic data. The processing unit implements the functions of: detecting, from the image represented by the electronic data, a first pattern having a first size and shape that is attached to the image; measuring a degree of degradation by measuring an amount of displacement of the size of the detected first pattern from the first size; and correcting the image represented by the electronic data to reduce the degree of degradation.
