"Forensic Identification of Fake Digital Photographs"

Abstract

The global impact resulting from the distribution of doctored digital photographs has reached an epidemic proportion. These digitally altered photos are distributed through social media, news outlets, traditional web resources and are making their way into the mainstream media. The impact of these photos can dramatically change the way people think, act, react, believe and can ultimately cause harm. At the simplest level they represent visual fraud.

During this presentation, I will convey real examples along with the resulting impacts that have already occurred.

Most importantly, I will demonstrate a new methodology rooted in the dark art of steganography that can actively identify these fraudulent photos and even trace their origins back to their creators.
