New research reveals privacy risks in fine-tuned LLMs

A new research paper published on arXiv explores the privacy risks associated with supervised fine-tuning (SFT) of large language models. Researchers demonstrated that personally identifiable information (PII) can be reconstructed from models trained on proprietary datasets, particularly in sensitive domains like medical and legal settings. They developed a novel decoding algorithm called COVA, which enhances an adversary's ability to recover PII by leveraging contextual knowledge and multi-turn interactions, highlighting significant privacy leakage concerns in SFT models.
