Sniffing out deepfakes by knowing your moves

Longtime Adobe collaborator Prof. Hany Farid writes,

Led by the incredibly talented Matyáš Boháček, we have built a new behavioral model that combines both facial and gestural characteristics to distinguish a real person from a deep-fake impersonator. We show the efficacy of this model in protecting Ukrainian President Zelenskyy from deep-fake imposters.

The paper says,

We describe a facial and gestural behavioral model that captures distinctive characteristics of Zelenskyy’s speaking style. Trained on over eight hours of authentic video from four different settings, we show that this behavioral model can distinguish Zelenskyy from deep-fake imposters.This model can play an important role–particularly during the fog of war–in distinguishing the real from the fake.
