Exposing Digital Forgeries by Detecting Traces of Image Splicing

In this paper, we investigate the trace of seamless splicing for blind image splicing. Image splicing is an essential operation for digital photomontage, which in turn is a technique for creating image forgery. Although good forgeries may leave no visual clues of having been tampered with, they may, nevertheless, alter the underlying statistics of an image. Through investigating the observation of the photomontages, we find the specific correlations in the image, which can be detected and used as evidence of digital tampering. The features derived from the proposal are useful and are proved by experimentation
