摘要： This invention allows verifying whether or not an original image content has been altered, to specify all edit processes applied to the original image content, and to hold the edited content. To this end, upon inputting a digital content file to be edited, first verification data included in that file is verified. After the content is edited, edit record information for the content is generated. Upon completion of the edit process and outputting the edited content, second verification data is generated based on the verification result of first verification unit, the edit record, and the edited content. The edited content, the edit record, the verification result of the first verification unit, and the second verification data are combined as an edited digital content file, and the combined file is output.

摘要： A semiconductor device including an AND-NOR composite gate of which AND unit is supplied with input signals IN and VDD and NOR unit is supplied with an inverted signal EB of an enable signal E, and an AND-NOR composite gate of which AND unit is supplied with an input signal INB and an enable signal E and NOR unit is supplied with VSS. These gates are inserted into a path to which the input signals IN and INB are supplied. Thereby, a symmetric property of a complimentary signal can be retained. Further, outputs of the AND-NOR composite gates are fixed irrespective of a logical level of the enable signal E. Thus, a sub-threshold current also is inhibited.

摘要： 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.

摘要： 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.
