Abstract

Digital Images are the reliable means of communicating visual information. It finds a wide range of application in our day-to-day life such as evidence. Throughout our day, what we come across almost all the time are images. In today's sophisticated world of advanced technologies, the reliability of these digital images has been put into question. This is because of the widely available image processing software's that even a novice tampers and creates a synthetic image, counterfeiting both its origin and content. Moreover the technology advent has also led to these forgeries difficult to distinguish from the authentic photographs. It incorporates a skilful tampering of images whereby, deceiving the viewers and avoiding further suspicion. Thus a number of digital image forensic techniques have been developed to verify the authenticity of digital images. This paper gives an idea on the digital image forensics and a survey specially focusing on the Block based copy move forgery detection method.
