Could LLM Watermark Detection be Public?

This work quantifies whether a public detector would be an additional liability in a deployment setting at varying levels of access, and introduces a split-key public-private watermarking method that exposes one key through a public detector while keeping the other for full verification and forensics.

TTMark: Pairwise Distortion-Free Watermarking Beyond Single-Token Entropy

Tandem Token WaterMark (TTMARK), a general pairwise watermarking framework that extends distortion-free watermarking from individual tokens to adjacent token pairs, and introduces a branch-isolating concatenated tandem generation algorithm that efficiently constructs the joint distribution in a single forward pass.

More Haste, Less Speed: Weaker Single-Layer Watermark Improves Distortion-Free Watermark Ensembles

This work proposes a general framework that utilizes weaker single-layer watermarks to preserve the entropy required for effective multi-layer ensembling and demonstrates that this counter-intuitive strategy mitigates signal decay and consistently outperforms strong baselines in both detectability and robustness.
