  • Informatics Colloquium 3.12. Differential Imaging Forensics

    Informatics Colloquium 3.12. 2019, 14:00 lecture hall D2 prof. Jianxin Yan, Department of Computer and Information Science, Linköping University, Sweden Differential Imaging Forensics Abstract: Given a single photo, is it possible to deduce who was the cameraman? To resolve this problem, I teamed up with Aurélien Bourquard (MIT) for a collaboration, codenamed Project C(razy). Along the way, we have invented some new forensics, which we call Differential Imaging Forensics (DIF). The DIF paradigm has practical applications in crime investigation and surveillance; it also informs intelligence operations. We also identified some unanticipated applications (e.g. deepfake detection), as well as many future research opportunities. (The only prerequisite assumed for this talk, if any, perhaps is a curious mind. No technical prerequisite is required.)
