HiMark: Hierarchical and Controllable Multi-bit Watermarking for Large Language Models
HiMark introduces hierarchical multi-bit watermarking for LLM outputs, advancing technical readiness for the content-provenance labelling the EU AI Act will require.

arXiv:2610.30601v1 Announce Type: new Abstract: With the rapid adoption of large language models (LLMs) in text generation applications, it has become increasingly difficult to trace generated content and assign responsibility for its use, raising concerns about provenance, copyright protection, and accountability. Multi-bit watermarking addresses these issues by embedding multi-bit provenance information into generated text, but reliable extraction remains difficult due to sparse per-bit evide
Editorial Analysis
EU AI Act transparency obligations will require technical measures for labelling AI-generated content; hierarchical watermarking schemes offer a more granular and robust approach than current methods.
