FakeTracer: Proactively Defending Against Face-swap DeepFakes via Implanting Traces in Training

no code implementations27 Jul 2023 Pu Sun, Honggang Qi, Yuezun Li, Siwei Lyu

Face-swap DeepFake is an emerging AI-based face forgery technique that can replace the original face in a video with a generated face of the target identity while retaining consistent facial attributes such as expression and orientation.

Landmark Breaker: Obstructing DeepFake By Disturbing Landmark Extraction

no code implementations1 Feb 2021 Pu Sun, Yuezun Li, Honggang Qi, Siwei Lyu

In this paper, we describe Landmark Breaker, the first dedicated method to disrupt facial landmark extraction, and apply it to the obstruction of the generation of DeepFake videos. Our motivation is that disrupting the facial landmark extraction can affect the alignment of input face so as to degrade the DeepFake quality.
