InvZW: Invariant Feature Learning via Noise-Adversarial Training for Robust Image Zero-Watermarking

Abdullah All Tanvir, Frank Y. Shih, Xin Zhong

This paper introduces a novel deep learning framework for robust image zero-watermarking based on distortion-invariant feature learning. As a zero-watermarking scheme, our method l…

Watermarking Language Models through Language Models

Agnibh Dasgupta, Abdullah Tanvir, Xin Zhong

Watermarking the outputs of large language models (LLMs) is critical for provenance tracing, content regulation, and model accountability. Existing approaches often rely on access…
