TL;DR#
The proliferation of AI-generated text poses challenges for various institutions, leading to concerns regarding plagiarism and misinformation. Current watermarking schemes struggle with robustness against adversarial edits (insertions, deletions, and substitutions) in AI-generated content. Existing methods often rely on strong assumptions, such as the independence of edits or a model being equivalent to a binary symmetric channel, limiting their applicability and effectiveness in real-world scenarios.
This research introduces a novel watermarking scheme that provides provable guarantees for both undetectability and robustness against a constant fraction of adversarial edits. This is achieved through the development of specialized pseudorandom codes that are robust to insertions and deletions, along with a transformation to watermarking schemes for any language model. The approach significantly improves upon previous work by relaxing computational assumptions and providing a more realistic robustness guarantee.

Why does it matter?#
This paper is crucial for researchers working on AI safety and security, particularly those focused on detecting and mitigating the misuse of AI-generated content. It offers a novel approach to watermarking language models that is more robust to adversarial attacks than previous methods. This robustness is particularly important considering the increasing prevalence of AI-generated content, opening new avenues for watermarking research and development.
