Where Does the Watermark Hide? Push-Pull Disentanglement for Invisible Watermark Removal
Jidong Yang, Huaike Yu, Qi Li +4
Fixed image distortions do not cover an attacker that learns from paired clean and watermarked images. We study this paired-training threat with single-image inference: deployment…
RemTraceNet: Few-Shot Forensic Detection of Invisible Watermark Attacks
Jidong Yang, Huaike Yu, Qi Li +6
Removing an invisible watermark and concealing the forensic evidence are distinct objectives: successfully disrupting the embedded watermark does not imply that the removal process…
Disentangle and Drop: Robust Universal Removal of Image Watermarks via Reconstructive Grayscale Residual Decomposition
Qi Li, Jidong Yang, Feng-Lei Fan +7
Invisible image watermarks are commonly evaluated against benign postprocessing operations such as compression, resizing, blur, and color changes. These tests leave out a different…
Style as Cover: Deep Image Steganography via Stylized Transmission
Qi Li, Jidong Yang, Huaike Yu +6
Image steganography hides secret message within normal images, with most existing works relying on cover-preserving transmission. However, such a paradigm becomes vulnerable once t…
One Prompt Is Enough: Watermark Laundering Through Foundation Image Models
Jidong Yang, Qi Li, Wei Zong +5
Invisible watermarks are typically evaluated against predefined perturbations such as compression, blur, noise, cropping, and denoising. Public foundation image models expose a dis…
SPFM-Net: Semantic-Prior-Guided Frequency-Constrained Mamba for Invisible Watermark Attack
Chunpeng Wang, Yanan Shi, Zhiqiu Xia +3
Existing watermark attacks typically rely on predefined signal-processing operations or locally constrained restoration networks, making it difficult to capture the long-range depe…
FDDWAN: A Frequency-Decoupled Diffusion Network for Watermarking Attack
Chunpeng Wang, Yuxin Li, Xiaoyu Wang +3
Existing invisible watermark removal methods often struggle to accurately capture the watermark-bearing features, leading to an unfavorable trade-off between watermark suppression…
