A color verification system of an aspect of the present invention includes an information processing apparatus that generates a job and an image forming apparatus that forms a color image on a sheet on the basis of the job. The information processing apparatus includes a storage portion that stores: information of the image forming apparatus under management; and target information including a target profile set to the image forming apparatus. Furthermore, when a plurality of different target profiles is set to the image forming apparatus, the information processing apparatus includes a job generation portion that generates the job: including image data containing a plurality of color verification images associated with the plurality of target profiles, respectively; and including an output setting.

The present disclosure relates generally to data hiding for retail product packaging and other printed objects. One embodiment embeds an information signal in a spot color for product packaging. The spot color is screened, and overprinted with process color tint. The tint is modulated prior to overprinting with optimized signal tweaks. The optimization can include consideration of a detector spectral dependency (e.g., red and/or green illumination). Many other embodiments and combinations are described in the subject patent document.

Information processing with detection of the falsification of an image is disclosed. In one example, an information processing device includes a color conversion unit that makes an estimate of color conversion applied to a second image generated by image editing on a first image, and outputs a color conversion trial result in which color conversion according to the estimate is applied to the first image. A judgement unit compares the color conversion trial result with the second image to judge the presence or absence of falsification in the second image. The technology can be applied, for example, to a falsification detection system that detects whether image editing for falsifying an image has been performed when the image is uploaded to social media.
