Copy-Move-Forgery (CMF) is one of the common ways of tampering digital images. Forging an image has become very easy and visually confusing to detect it from the authentic one. Broadly speaking, CMF detection methods generally use either block-based or feature point-based approaches. In this paper, we proposed a new technique called keypoint based Circle-Block model in which first keypoints are extracted; then Circle-blocks are constructed centering the keypoints. Block matching is made using color and pixels behavior of the blocks.
