A Review Paper on Copy Move Forgery Detection Techniques

Abstract

Digital images are easy to manipulate and edit due to availability of powerful image processing and editing software. Nowadays, it is possible to add or remove important features from an image without leaving any obvious traces of tampering. As digital cameras and video cameras replace their analog counterparts, the need for authenticating digital images, validating their content and detecting forgeries will only increase. This paper reviews the detection techniques for copy move forgery tampering attacks. The copy-move attack in which a part of the image is copied and pasted somewhere else in the image with the intent to cover an important image feature is discussed in particular. It is done for hiding some image object, or adding more details resulting in atleast some part being cloned.
