A Google TechTalk, 2025-06-18, presented by Nikola JovanovićPrivacy in ML Seminar. ABSTRACT: As generative AI becomes more capable and increasingly integrated into everyday tools and platforms, watermarking has emerged as a promising technique for content attribution, provenance tracking, and misuse detection. This talk presents recent advances and challenges in watermarking, focusing on autoregressive generative models. First, we expose vulnerabilities in current LLM watermarking schemes by introducing a novel class of adversaries capable of cheaply mounting both spoofing and removal attacks. Second, we shift to defense, demonstrating how LLM watermarks can be repurposed to enable data owners to provably detect unauthorized use of their content in retrieval-augmented generation (RAG) systems. Finally, we extend token-level watermarking to autoregressive image generation models, a paradigm that has recently gained traction, by identifying and addressing key modality-specific challenges, enabling a theoretically principled, strong, and robust watermark.Uploaded 26-01-26
