Abstract: Adversarial machine learning (ML) has been a hot research topic in ML community, showing that many state-of-the-art, sophistically designed ML algorithms can be easily fooled.  Meanwhile, image forensics and anti-forensics have been extensively studied in the multimedia security community for over a decade. In this talk, our recent work on SIFT keypoint removal/injection is used an example to demonstrate that adversarial ML is closely connected to image forensics from many aspects.
