Paolo Bestagini gave a talk on video forensics at the Institute of Computing (IC) of the State University of Campinas (UNICAMP) invited by Prof. Anderson Rocha.
Abstract: The recent development of multimedia devices and editing tools, together with the proliferation of video sharing websites, has made the acquisition, alteration, and diffusion of video content relatively easy tasks. As a consequence, it is possible to find more and more video sequences available on the Internet, but each of them has been potentially tampered with by anyone. It is then clear that the development of tools that enable the recovery of past history of video sequences in order to prove their origin and authenticity is more than an urgent necessity. In this talk, we discuss some of the video forensic techniques that have been proposed in the last few years. Specifically, we will focus on blind forensic methods exploiting either model-based or data-driven solutions.
