SimMark: A Robust Sentence-Level Similarity-Based Watermarking Algorithm for Large Language Models
EMNLP 2025
The widespread adoption of large language models (LLMs) necessitates reliable methods to detect LLM-generated text. We introduce SimMark, a robust sentence-level watermarking algorithm that makes LLMs’ outputs traceable without requiring access to model internals, making it compatible with both open
