Global Sketch-Based Watermarking for Diffusion Language Models
Researchers have developed new methods for watermarking diffusion language models to ensure content provenance. One approach, "Global Sketch-Based Watermarking," uses a global sketch representation of text, decoupling detection from local contexts and offering order-agnostic statistics. Another method, DiffMark, is a plug-and-play framework that embeds a persistent perturbation during denoising steps, enabling fast, multi-bit extraction and cross-architecture transferability without retraining.
