    Abstract: This patent document relates generally to steganography and digital watermarking. One claim recites an apparatus comprising: memory for storing data representing an image or video, in which the data comprises first data corresponding to first color data, second data corresponding to second color data and third data corresponding to third color data, the image or video to host auxiliary information; a processor programmed for: weighting the first data, the second data and the third data according to at least the following two factors: i) a color direction associated with an expected embedding direction; and ii) expected image capture or signal processing; and determining from weighted first data, weighted second data and weighted third data, changes in one or more image or video attribute(s), in which the auxiliary information is conveyed through the changes. Of course, other claims and combinations are provided too.

    Abstract: This invention can generate printed matter on which a multi-valued discrimination image of three values or more cannot be visually confirmed under ordinary light but can be visually confirmed via an infrared camera under infrared light. To this end, a holding unit holds items of color information C1, C2, and C3 each indicating usage amounts of printing materials of three types, used by a printing apparatus, which have a color difference under visible light not more than a pre-set threshold, and which have different infrared light ray absorption rates. When a latent image generating unit generates infrared light ray latent image data of three tones, a discrimination image data generating unit decides one color information item Ci (1≦i≦3) held by the holding unit, and outputs the decided Ci to an output unit which outputs the received pixel values to the printing apparatus.

    Abstract: This patent document relates generally to steganography and digital watermarking. One claim recites, a method of encoding auxiliary information in an image or video. The method includes: determining a watermark tweak for an attribute of an image or video sample to encode auxiliary information in the image or video; and altering color values of the image or video sample to effect the watermark tweak, said altering alters color values based at least in part on both: i) visibility of color value alterations, and ii) anticipated watermark detection. Of course, other claims are provided too.
