Nowadays, the pervasiveness of images and videos as primary sources of information has led the image forensics community to question their reliability and integrity more and more often. Image and video forensics were developed to deal with the need to verify the trustworthiness of such multimedia contents, determining their authenticity and origin. In fact, recovering from digital evidence as much information as possible about the acquiring device or on the processing that has been applied could be fundamental to understand if an image is authentic or has been manipulated to change its meaning. In particular, it could be of basic importance to succeed in reconstructing the history of a specific image or video that might help in addressing an on-going forensic investigation or in debunking of certain news.
