Digital images can now be easily created, altered, and manipulated with no obvious traces of having been subjected to any of these operations. There are currently no established methodologies to verify the authenticity and integrity of digital images in an automatic manner. Digital image forensics is an emerging research field with important implications for ensuring the credibility of digital images. In an attempt to assist these efforts, this chapter surveys the recent developments in the

Proposed techniques in the literature are categorized into three primary areas based on their focus: image source identification, discrimination of synthetic images, and image forgery detection. The main idea of the proposed approaches in each category is described in detail, and reported results are discussed to evaluate the potential of the methods.
