Screen-Conditioned Watermarking Against Multi-Screen Collusion Attacks
Mingyue Chen, Xin Liao, Yufeng Wu +2
Screen-shooting poses a significant threat to confidential information protection. While existing screen-shooting watermarking methods enable copyright verification, the copyrighte…
NiMark: A Non-intrusive Watermarking Framework against Screen-shooting Attacks
Yufeng Wu, Xin Liao, Baowei Wang +3
Unauthorized screen-shooting poses a critical data leakage risk. Resisting screen-shooting attacks typically requires high-strength watermark embedding, inevitably degrading the co…
DDNet: A Dual-Stream Graph Learning and Disentanglement Framework for Temporal Forgery Localization
Boyang Zhao, Xin Liao, Jiaxin Chen +2
The rapid evolution of AIGC technology enables misleading viewers by tampering mere small segments within a video, rendering video-level detection inaccurate and unpersuasive. Cons…
Sim-to-Real: An Unsupervised Noise Layer for Screen-Camera Watermarking Robustness
Yufeng Wu, Xin Liao, Baowei Wang +4
Unauthorized screen capturing and dissemination pose severe security threats such as data leakage and information theft. Several studies propose robust watermarking methods to trac…
