arXiv:2605.25796v1 Announce Type: cross Abstract: Semantic-level watermarking (SWM) improves robustness against text modifications by treating sentences as the basic unit. However, robustness to paragraph-level paraphrasing remains difficult because such attacks globally disrupt watermark signals by changing sentence order. In this work, we propose SAMark, a self-anchored watermarking framework that removes the dependency on sentence order by establishing a step-independent green region in semantic space. To improve detectability, we introduce a multi-channel hyperbolic scoring mechanism that
The proliferation of advanced generative AI models necessitates robust methods to ensure content authenticity and attribution, driving rapid innovation in watermarking techniques.
Sophisticated watermarking like SAMark is crucial for mitigating risks associated with misinformation, intellectual property theft, and the blurring lines between AI-generated and human-created content, impacting trust in information.
The ability to watermark text with enhanced robustness against semantic-level evasions, particularly paragraph-level paraphrasing, significantly improves the integrity and traceability of AI-generated content.

Increased trust and accountability in large language model outputs are enabled by more resilient watermarking methods.
This could lead to widespread adoption of mandatory watermarking for AI-generated text, influencing platform policies and regulatory frameworks.
The development of advanced watermarking may also spur a cat-and-mouse game with increasingly sophisticated removal techniques, driving further research and development in both areas.
