Image forgery detection is emerging as one of the hot research topic in the area of image forensics. In this modern digital era due to availability of advanced technology, powerful computer photo editing tools and software packages digital images can be easily forged. In the fields such as forensics, medical imaging, industrial photography and e-commerce authenticating the originality of images and detecting traces of manipulation without any prior knowledge of the image content or any embedded information is a challenging task and quite impossible to say images are authentic. As a result, photographs have almost lost their trustworthiness.
