The malicious applications of deep forgery, represented by face swapping,
have introduced security threats such as misinformation dissemination and
identity fraud. While some research has proposed the use of robust watermarking
methods to trace the copyright of facial images for post-event traceability,
these methods cannot effectively prevent the generation of forgeries at the
source and curb their dissemination. To address this problem, we propose a
novel comprehensive active defense mechanism that combines traceability and
adversariality, called Dual Defense. Dual Defense invisibly embeds a single
robust watermark within the target face to actively respond to sudden cases of
malicious face swapping. It disrupts the output of the face swapping model
while maintaining the integrity of watermark information throughout the entire
dissemination process. This allows for watermark extraction at any stage of
image tracking for traceability. Specifically, we introduce a watermark
embedding network based on original-domain feature impersonation attack. This
network learns robust adversarial features of target facial images and embeds
watermarks, seeking a well-balanced trade-off between watermark invisibility,
adversariality, and traceability through perceptual adversarial encoding
strategies. Extensive experiments demonstrate that Dual Defense achieves
optimal overall defense success rates and exhibits promising universality in
anti-face swapping tasks and dataset generalization ability. It maintains
impressive adversariality and traceability in both original and robust
settings, surpassing current forgery defense methods that possess only one of
these capabilities, including CMUA-Watermark, Anti-Forgery, FakeTagger, or PGD
methods.
