Easy access to digital cameras and photo editing software has resulted in creating counterfeiting images and changing the content of
original ones. So the reliability and authenticity of digital media for a court of law is now questionable. Any processing on images to
transform a photograph into a desired image such as adding/ removing people or objects from the image scene, adjusting the
brightness and contrast, scaling, rotating some parts of the image is called “image manipulation” or image forgery.
Digital Image Forensics (DIF) is an emerging subject which studies tools and methods for distinction of authentic images from
digitally manipulated ones
