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.
