A new study published on arXiv investigates the privacy risks associated with large language models (LLMs) when used in interactive and retrieval-augmented systems. The research introduces a unified threat model and conducts an ablation study to assess the impact of factors like model architecture, scale, and dataset characteristics on various privacy attacks. Findings indicate that membership inference attacks are generally reliable, while backdoor attacks are consistently successful due to their trigger-based nature. Attribute inference and data extraction attacks, though less accurate, pose significant risks by targeting sensitive personal information. AI
