Gotcha: A Challenge-Response System for Real-Time Deepfake Detection. (arXiv:2210.06186v1 [cs.CR])
cs.CR updates on arXiv.org arxiv.org
The integrity of online video interactions is threatened by the widespread
rise of AI-enabled high-quality deepfakes that are now deployable in real-time.
This paper presents Gotcha, a real-time deepfake detection system for live
video interactions. The core principle underlying Gotcha is the presentation of
a specially chosen cascade of both active and passive challenges to video
conference participants. Active challenges include inducing changes in face
occlusion, face expression, view angle, and ambiance; passive challenges
include digital manipulation of the webcam …
