    Abstract: A forensic marking system and method for identifying the printing device on which a medium was printed. Encoded forensic markings which identify the device but are of low perceptibility to the human eye are superimposed on the printed image. The markings have a color, size, density, and repetition pattern that only minimally affect print quality while providing highly accurate identification of the printing device, even if the printed medium contains high-density image content.

    Abstract: In an image processing apparatus, an antenna is arranged in a traveling member of a scanner, a reader/writer receives a radio wave from a radio tag added to an original via the antenna when the reader/writer reads an image from the original, a demodulation circuit generates a demodulated signal, a radio tag identification number identifying and judging unit, which has received the demodulated signal, identifies a type of the radio tag, and when it is judged that the original is a forgery prevention object original, a forgery prevention processing unit applies forgery prevention processing to the original.

    Abstract: The present method concerns inserting manipulation-proof digital fingerprints into electronic documents making it possible to detect manipulations by purchasers or groups of purchasers. According to the present invention based on a predefined number of copies and a maximum number of copying hackers per document, a location or an area for the digital fingerprint of the customer is defined for each copy. All the locations or areas defined in the document for digital fingerprints are subject in their totality to an enclosed finite geometric ordering system, in which intersections of the digital fingerprints occur at defined locations or areas. By analyzing the intersection points not found by the hackers, the hackers involved in the manipulation can be uniquely determined. The method described is suitable, in particular, for identifying copies of documents which are subject to copyright protection.
