EditGuard: Versatile Image Watermarking for Tamper Localization and Copyright Protection

no code implementations CVPR 2024 Xuanyu Zhang, Runyi Li, Jiwen Yu, Youmin Xu, Weiqi Li, Jian Zhang

In the era where AI-generated content (AIGC) models can produce stunning and lifelike images, the lingering shadow of unauthorized reproductions and malicious tampering poses imminent threats to copyright integrity and information security.

CRoSS: Diffusion Model Makes Controllable, Robust and Secure Image Steganography

1 code implementation NeurIPS 2023 Jiwen Yu, Xuanyu Zhang, Youmin Xu, Jian Zhang

Current image steganography techniques are mainly focused on cover-based methods, which commonly have the risk of leaking secret images and poor robustness against degraded container images.

Large-capacity and Flexible Video Steganography via Invertible Neural Network

1 code implementation CVPR 2023 Chong Mou, Youmin Xu, Jiechong Song, Chen Zhao, Bernard Ghanem, Jian Zhang

For large-capacity, we present a reversible pipeline to perform multiple videos hiding and recovering through a single invertible neural network (INN).

Robust Invertible Image Steganography

no code implementations CVPR 2022 Youmin Xu, Chong Mou, Yujie Hu, Jingfen Xie, Jian Zhang

Previous image steganography methods are limited in hiding capacity and robustness, commonly vulnerable to distortion on container images such as Gaussian noise, Poisson noise, and lossy compression.
