Deepfakes: How they deceive us (and how we detect them)

Can you tell if a photo is generated by artificial intelligence (AI)? When is video evidence no evidence at all? What are the pros and cons of creating AI algorithms that have “imagination?”

Monday, Jan. 11, 5:30–7 p.m., Juston Moore, research scientist in the Advanced Cyber Systems group at Los Alamos National Laboratory, leads the virtual conversation, “Deepfakes and the AI-Enabled Misinformation Age,” the latest in the Science on Tap lecture series.

Juston is an expert in adversarial artificial intelligence. He will discuss deepfakes, which are fake images, videos, audio and other media created by artificial intelligence algorithms. While some deepfakes are entertaining, such as actor Nicolas Cage’s face superimposed on Yoda’s body, the potential to make malicious deepfakes of political leaders, false disasters or other misleading content raises questions about the weaponization of information and its impact on law enforcement and national security.

Juston will discuss why we are seeing the emergence of deepfakes now and the potential approaches to reduce risk of AI-generated misinformation.

Juston received a bachelor’s in computer science from New Mexico Institute of Mining and Technology and a master’s in computer science from the University of Massachusetts, Amherst. He joined the Lab as a graduate research assistant and has been a cyber data scientist since 2016. Juston’s research applies machine learning and statistics to solve problems in network security and information assurance. His primary contributions at Los Alamos include developing REDUCE, an open-source toolset for statistically guided malware analysis, and leading a team to build detectors for deepfake images and videos.

Science on Tap is a convivial opportunity to engage with Lab scientists on their current projects. A brief presentation is followed by questions, answers and discussion. The fun takes place on the third Monday of each month from 5:30 to 7 p.m. virtually — and eventually at local watering holes in Los Alamos and White Rock. The free lecture series is a joint project between the Bradbury and the Los Alamos Creative District.
