Copy Paste Detection from the Color Images Using DWT

As the use of digital multimedia content such as images and video has increased, so the incentive to create digital forgeries. Presently, powerful editing software allows forgers to create perceptually convincing digital forgeries. Accordingly, there is a great need for techniques capable of authenticating digital multimedia content. In response to this, researchers have begun developing digital forensic techniques capable of identifying digital forgeries. We use DWT and different filters for forensic tasks such as identifying cut-and-paste forgeries from JPEG compressed images. Additionally, we consider the problem of multimedia security from the forger's point of view. We demonstrate the technique that is used to detect the copy paste part from the colour image. In this tempered image is their that is used to detect the temper image and calculate the frames and their PSNR values.
