摘要： A figure pattern (113, 711) expressing information to be embedded (112, 713), or a position of an area in which the information to be embedded exists, is embedded in an area other than the background of image data (111, 601, 712, 1801), thereby generating image data embedded with a watermark (114, 602, 715, 1802) . Then, the figure pattern is detected from the generated image data embedded with the watermark, and embedded information expressed by the detected figure pattern or embedded information existing in an area at a position expressed by the detected figure pattern is detected.

摘要： A storing unit (311) stores video information (611) obtained by photographing an object illuminated by light in which embedded information is superimposed onto a plurality of components in a color space. A detecting unit (312) emphasizes a signal obtained from an image included in the video information on the basis of a result of emphasizing a first color component more than a second color component according to a spectral reflection characteristic (612) in a range including the object, and detects the embedded information from the emphasized signal, the first color component and the second color component being from among a plurality of color components that correspond to a plurality of wavelengths, the first color component having a reflectance higher than a reflectance of the second color component. An output unit (313) outputs information on the basis of the embedded information detected by the detecting unit.

摘要： In an image encryption apparatus, each of pixel-value inverse-converters applies pixel-value inverse-conversion on an input image in each of previously-encrypted areas. An image combiner superimposes images with inversely-converted pixels in the previously-encrypted areas to the input image to obtain a ready-to-encrypt image. An image encryptor scrambles blocks in the ready-to-encrypt image. A pixel-value converter applies pixel-value conversion on each of scrambled blocks to obtain a multiply-encrypted image. In an image decryption apparatus, a pixel-value inverse-converter applies pixel-value inverse-conversion on each scrambled block in the multiply-encrypted image to obtain a dot-erased image. An image decryptor inversely scrambles the scrambled blocks in the dot-erased image to obtain a decrypted image. Each of pixel-value converters applies pixel-value conversion on the decrypted image in each of previously-encrypted areas. An image combiner superimposes images with converted pixels in the previously-encrypted areas to the decrypted image to obtain a previously-encrypted image.

摘要： Area data indicating an encryption area of image data and level data indicating an authority level for the encryption area are received. Upon being triggered by an input password, an encryption key is generated for each received authority level. Check data to be detected in verifying whether or not the encrypted image data in the encryption area is appropriately decrypted through decryption is implanted in the encryption area. Image encryption is performed on the encryption area where the check data is implanted, by using the encryption key corresponding to the authority level designated for the encryption area. In decryption, all decryption keys corresponding to all authority levels lower than or equal to the set authority level are used to decrypt each encryption area and determines whether or not an appropriate decryption has been performed on the basis of the result of the detection of the check data.
