ArcMark is a multi-byte LLM watermark that achieves distortion-free embedding of several bytes per few hundred tokens by treating generation as a channel coding problem and using optimal transport to match distributions.
Derives matched converse and achievability bounds that characterize optimal trade-offs among false-alarm probability, detection error probability, distortion, and information rate for multi-bit watermarking of stationary ergodic stochastic processes.
