Abstract: Copy move forgery is a region duplication forgery in which a part of a digital image is copied and pasted within the same image. Many algorithms have been developed for detecting the copy move forgery. Copy move forgery is mainly classified into two types which is block based and keypoint based. The block based method includes PCA, DCT, DWT etc and key point based method includes SIFT and SURF. This paper will include a detail study of different image forgery detection techniques, different tampering techniques and a detailed study of different block based and keypoint based method.
Keywords: Copy Move Forgery, DCT, DWT, SIFT, SURF
