This seminar is part of the Jones Seminars on Science, Technology, and Society series.
From the tabloid magazines to main-stream media outlets, political campaigns, courtrooms, and the photo hoaxes that land in our email, doctored photographs are appearing with a growing frequency and sophistication. The resulting lack of trust is impacting law enforcement, national security, the media, e-commerce, and more. The field of digital photo forensics has emerged to help return some trust in digital photographs. In the absence of any digital watermark or signature, we work on the assumption that most forms of tampering will disturb some statistical, physical, or geometric property of an image. To the extent that these perturbations can be quantified and detected, they can be used to invalidate or authenticate a photo. I will provide a broad overview of our work in this area.
