Abstract In the article the digital cameras and scanner identification possibility based on digital images formed by them is presented. The digital images preprocessing algorithm for digital cameras non-uniformity map creation, which allows to reduce the necessary number of images to create the sensor’s non-uniformity map. The modification of the presented algorithm adapted for scanner non-uniformity map creation is presented. The experimental exploration of algorithms and evaluations of digital recording devices identification accuracy are given based on digital cameras and scanners identification.
