Abstract
Verifying the content of digital images or identifying forged regions would be obviously useful when digital pictures are presented as evidence. We present a curvelet logo watermark based on the image fusion approach. The forgery is determined as the one which lacks the logo watermark. We have used structural distortion approach for integrity verification which we have tested on examples of real forgeries. We have also investigated the effect of attacks such as lossy compression, brightness, etc. Region of interest influences our approach to verify image integrity.
