Just Deepfakes

Just Deepfakes

Original Release Date: August 27, 2020

In episode seven of our 2020 Digital Evidence season, Just Science interviews Dr. Catalin Grigoras and Cole Whitecotton from the National Center for Media Forensics about deepfakes.

Deepfakes are a form of synthetic media that replace an existing image with someone else’s likeness. While relatively new, deepfake technology has grown in sophistication over the last few years. In some cases, the synthetic image is almost indiscernible from the person that it is imitating, which can create a lot of problems for forensic analysts. Dr. Catalin Grigoras and Cole Whitecotton are working to understand and combat deepfakes. Listen along as they discuss the capability, implications, and the future of deepfake technology in this episode of Just Science.

This episode of Just Science is funded by the National Institute of Justice’s Forensic Technology Center of Excellence [Award 2016-MU-BX-K110].
