arXiv:2606.00613v1 Announce Type: new Abstract: Watermarking should identify language-model output without degrading quality or limiting verification to the model provider. Multilingual deployment makes this harder because morphology, segmentation, and script change where watermark evidence can enter naturally. We introduce LUNA, a linguistically adaptive watermark that combines model-free detection with single-token non-distortion under the standard random-key model. LUNA estimates normalized next-tag entropy from part-of-speech contexts in an external corpus and uses it to set the depth of a
The proliferation of powerful LLMs and the increasing need for provenance and authenticity in AI-generated content drive the urgent development of advanced watermarking techniques.
This development addresses a critical challenge in AI ethics and content integrity, ensuring that AI output can be identified without compromising quality, which is vital for trust and accountability in AI systems.
The ability to accurately watermark multilingual LLM output without distortion radically improves the verifiability and auditability of AI-generated text, shifting the landscape of content provenance.
