Passive Image Forensic Method to detect Copy Move Forgery in Digital Images

IOSR Journal of Computer Engineering, 2014
Tampering in digital images has become very easy due to the availability of advanced image editing softwares to the users. Images are being tampered in a very efficient manner without leaving any visual clue. As a consequence, the content of digital images cannot be taken as for granted. There are various types of image tampering techniques. One of the
