With the development of image editing software such as Adobe Photoshop, digital image can easily be manipulated and hardly detected by human eyes. If we take this issue for granted, it may eventually be harmful for our digital world, especially for the credibility of news coverage. Many researchers have worked on image forensics and a number of image tampering detection techniques have been proposed in recent years.
