Abstract: Additional information is embedded in document data by inputting document data, inputting additional information, and inputting image data. The additional information is embedded in the input image data using a first digital watermark method, and the additional information is embedded in the input document data using a second digital watermark method. The document data embedded with the additional information is composited with the image data embedded with the additional information, with the image data as a background image. In a case where an original document containing information embedded using the second digital watermark method is copied by a copying machine, the information embedded in the copied document cannot be detected. The first digital watermark method has a robustness such that, when an original document containing information embedded using the first digital watermark method is copied by a copying machine, information embedded in the copied document can be detected.

Abstract: Whether or not information has been tampered with can be detected while authentication information is set to be inseparable from digital information, and original digital data can be restored as long as it is free from tampering. For this purpose, when authentication information is embedded into digital information input by an image input unit (201), a Hash value calculation unit (202) generates authentication information based on that digital information, an encryption unit (203) encrypts the authentication information using an encryption key, and a digital watermarking unit (204) embeds the encrypted information in the digital information as a digital watermark.

Abstract: In a semiconductor memory, in order to eliminate unbalance of the coupling capacitance between a bit line and a bus line so as to prevent noises from occurring, a layer of a column selection signal line is disposed in an intermediate layer position between a layer of the bit line and a layer of the bus line. Also, the width of the column selection line is increased to cover the bit lines whose width are different from each other due to a contact, to thereby shield the bit line and the bus line by the column selection signal line, and to balance of the coupling capacitance between the bit line and the bus line.

Abstract: A array including array elements in a number smaller than the minimum number of pixels, having values larger than Th_c, and a plurality of array elements having values smaller than Th_c is generated. A formation array having the same size as that of a latent image is generated from the generated array. An image obtained by replacing the pixel value at a pixel position within the first region in the latent image with the value at the pixel position in the formation array is generated as a configuration image. The pixel value at each pixel position in the configuration image, that corresponds to each pixel position in the input image, is output as the amount of a highly infrared absorbent color material used to print a pixel at this pixel position in the input image.
