Copy-move image forgery is carried out by copying a specific region from an image and pasting the copied image segment elsewhere in the same image. Copy-move forgery may be carried out to hide something within the image, or to increase number of objects in an image, for example, in the widely popular fake Iranian missiles image, in which copy-move forgery is employed to hide a miss fired missile with a fired missile. Because the duplicated image segments originate from the same original image, all of the image features, for example, noise patterns, color distribution, dynamic range etc remain unchanged from the original image. This is why it is almost impossible for a human eye to notice these kind of forgeries in images. If done professionally with available advanced image manipulation software, this kind of forgery is difficult to detect even using the advanced multimedia forensics tools as well.
