Can LLM Watermarks Robustly Prevent Unauthorized Knowledge Distillation?

ACL 2025long

The radioactive nature of Large Language Model (LLM) watermarking enables the detection of watermarks inherited by student models when trained on the outputs of watermarked teacher models, making it a promising tool for preventing unauthorized knowledge distillation. However, the robustness of water…

WaterSeeker: Pioneering Efficient Detection of Watermarked Segments in Large Documents

NAACL 2025findings

Watermarking algorithms for large language models (LLMs) have attained high accuracy in detecting LLM-generated text. However, existing methods primarily focus on distinguishing fully watermarked text from non-watermarked text, overlooking real-world scenarios where LLMs generate only small sections…

A Semantic Invariant Robust Watermark for Large Language Models

ICLR 2024poster

Watermark algorithms for large language models (LLMs) have achieved extremely high accuracy in detecting text generated by LLMs. Such algorithms typically involve adding extra watermark logits to the LLM's logits at each generation step. However, prior algorithms face a trade-off between attack robu…
