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.)
