A new research paper published on arXiv explores the complex relationship between memorization and differential privacy in large language models. The study identifies that current differential privacy (DP) methods, often used as a proxy for preventing memorization, do not uniformly control all forms of data extraction. Researchers have established precise DP bounds for counterfactual memorization and adaptive extraction, demonstrating that these two aspects do not necessarily correlate. The paper highlights that DP can cap memorization while still allowing for extraction, and vice versa, creating blind spots for current auditing and unlearning verification methods, even in large-scale models.
