Passive Forgery Detection Techniques:A Survey

The practice of altering images without authorization is referred to as digital image forgery (DIF). Digital manipulation is now a reasonably simple technique. The primary research topics for the detection of image forgeries are two categories of image forgery: copy-move and image splicing forgery. A piece of an input image is copied, and then another section of the same digital image has the copied section pasted over it this manipulation is called copy-move forgery. While splicing is a form of manipulation that merges various sections from the same or different sources to produce a composite forged image. However, this paper compared and analyzed two forgery techniques and attempted to describe recent findings in both kinds by gathering and organizing them according to the qualities that were employed.
