Is It Generated by AI? - Attacks and Robust Watermarking for Generative AI

Generative AI have demonstrated incredible power, but the synthetic generation also challenges authenticity of the content. In this talk, we will address two fundamental questions regarding responsible use of generative AI: (1) How can we accurately identify AI-generated text and images? (2) What measures can safeguard the intellectual property of GenAI? We will first present a strong image watermark attacking method and a paraphrasing-based text watermark attacking approach that are capable of removing watermarks. 

We will introduce two robust watermarking techniques designed for text and models. Our discussion will encompass the theoretical underpinnings that ensure the correctness of watermark detection, along with robustness against evasion attacks. These findings establish a solid technical groundwork for policymakers, legal professionals, and generative AI practitioners alike. joint work with Xuandong Zhao, Yu-Xiang Wang, Prabhanjan Ananth, Kexun Zhang
