Digital Image Authenticity Verification System

Abstract

In today's day today life digital images are available everywhere and it is very easy to manipulate these digital images by using powerful editing software. Now a day's many people add, crop or remove important features from an image without leaving any proof of fake images. There are many techniques used for forgery detection. One of the technique most commonly used is Copy-Move forgery in which coping a some part of image and pasting it into the same image in order to hide some data or part of an image and other most commonly used technique is staganalysis in which some message is hidden inside the image which is not easily possible to see with naked human eye. In this paper we search the problem of detecting the forgery and describe robust detection method. this method successfully detect the forged part even when the copied area is edited to combine it with the background of an image and even if the forged image is saved in the JPEG format.
