New research reveals type-dependent privacy risks in code LLMs

A new research paper published on arXiv explores the privacy risks associated with large language models for code (LLM4Code). The study, authored by Hua Yang, investigates how different types of personally identifiable information (PII) are learned and leaked by these models. The findings indicate that leakage risks vary significantly based on the PII type, with easily learnable data like IP addresses being more prone to leakage than complex data such as keys and passwords. This research provides the first causal evidence of type-dependent leakage and suggests methods for developing more effective privacy defenses for LLM4Code. AI

IMPACT Highlights the need for type-aware privacy defenses in code-generating LLMs.
