TTMark: Pairwise Distortion-Free Watermarking Beyond Single-Token Entropy
Distortion-free watermarking enables reliable attribution of machine-generated text while preserving output distribution. However, existing methods operate independently on each generated token, making their detection capability fundamentally constrained by the entropy of the next-token distribution. We present Tandem...
