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…

An Entropy-based Text Watermarking Detection Method

ACL 2024long

Text watermarking algorithms for large language models (LLMs) can effectively identify machine-generated texts by embedding and detecting hidden features in the text. Although the current text watermarking algorithms perform well in most high-entropy scenarios, its performance in low-entropy scenari…

MarkLLM: An Open-Source Toolkit for LLM Watermarking

EMNLP 2024system demonstrations

Watermarking for Large Language Models (LLMs), which embeds imperceptible yet algorithmically detectable signals in model outputs to identify LLM-generated text, has become crucial in mitigating the potential misuse of LLMs. However, the abundance of LLM watermarking algorithms, their intricate mech…
