摘要： In verification of image data of a captured image as to whether it is original one, the verification is possible even for image data subjected to a peripheral illumination correction or an exposure correction. An order information calculation unit selects a pixel set including two or more pixels based on pixel values and information on an image space of image data of a captured image, and calculates an order of magnitude between pixels in the selected pixel set. A verification data producing unit generates verification data used in verification of whether the image data has not been tampered with, based on the calculated order of magnitude. An image output unit outputs the image data and the verification data.

摘要： The invention enables a verifier to easily confirm that the image data was captured in the multiple exposure mode, and also to easily confirm which area in the image captured in the multiple exposure mode was greatly affected by multiple exposure. An image generating unit generates exposure image data pieces by exposing an image sensor a plurality of times. An image composition unit combines exposure image data pieces to generate a single piece of composite image data. A reference image generating unit generates reference image data composed of data pieces for distinguishing pixel positions at which the exposure amount exceeds a threshold from the other pixel positions. A verification data generating unit generates verification data for determining whether alteration has been made from the composite image data and the reference image data to output a single file.

摘要： This invention provides a technique of preventing determination of image alteration when digital image data has undergone, e.g., rotation without any substantial change in contents. To do this, an area separation processing unit separates image data into areas. For each of the separated areas, an area feature value calculator calculates an area feature value independent of the coordinate information of the image. An area order sorter sorts the separated areas in accordance with the calculated area feature values. A validation data generation processing unit generates validation data based on the sort result.
