To rotation, are almost always needed when two or more images verify the authenticity and further to trace back the processing are spliced together to create convincing image forgeries. In history of digital images, a number of techniques have been recent years, researchers have developed many digital forensic techniques to identify these operations. Most previous works in developed in the past few years. Among many other methods, this area focus on the analysis of images that have undergone passive forensic methods have attracted substantial research single geometric transformations, e.g., resizing or rotation. In interest since they do not require any additional information several
