Defining Cost Function of Steganography with Large Language Models

Hanzhou Wu, Yige Wang

In this paper, we make the first attempt towards defining cost function of steganography with large language models (LLMs), which is totally different from previous works that rely…

A Fingerprint for Large Language Models

Zhiguang Yang, Hanzhou Wu

Recent advances confirm that large language models (LLMs) can achieve state-of-the-art performance across various tasks. However, due to the resource-intensive nature of training L…

Yet Another Watermark for Large Language Models

Siyuan Bao, Ying Shi, Zhiguang Yang +2

Existing watermarking methods for large language models (LLMs) mainly embed watermark by adjusting the token sampling prediction or post-processing, lacking intrinsic coupling with…
