While existing forensic networks have demonstrated strong performance on image forgeries, recent results reported on the Adobe VideoSham dataset show that these networks fail to identify fake content in videos.

Understanding the transferability of adversarial attacks, i. e. an attacks ability to attack a different CNN than the one it was trained against, has important implications for designing CNNs that are resistant to attacks.

In this paper, we propose a new anti-forensic attack framework designed to remove forensic traces left by a variety of manipulation operations.

We propose new image forgery detection and localization algorithms by recasting these problems as graph-based community detection problems.

In this paper we introduce a new digital image forensics approach called forensic similarity, which determines whether two image patches contain the same forensic trace or different forensic traces.

Furthermore, forensic analysts need ‘general purpose’ forensic algorithms capable of detecting multiple different image manipulations.
