Comprehensive Display of Digital Image Copy-Move Forensics Techniques

Digital Images considered as a natural and effective communication media to the human, owing to the swiftly and the easy manner to comprehend their content. After the appearing of the high-quality digital camera, personal computers, and sophisticated photo editing software, the manipulation becomes more common. One of the most popular tools to manipulation is a copy-move forgery (CMF) that precedes via copying portion of the digital image and paste it into another position in the same image to conceal the object behind. In this paper, a comprehensive expansion of digital image copy-move detection techniques is presented to display the appropriate techniques which are presently used. Many algorithms have been developed, algorithms based on DCT, algorithms using invariant image moments, algorithms using texture and intensity descriptors, algorithms using invariant key points, algorithms based on mutual information, and algorithms based on SVD to determine the existence of digital image forgery.
