Researchers have developed PrivMeSA, a novel multi-agent system designed to enhance medical consultations using large language models (LLMs) while preserving patient privacy. This system allows local agents to consult more powerful remote LLMs by learning to control the disclosure of sensitive information. Through reinforcement learning, PrivMeSA balances task accuracy with the risk of re-identification, significantly reducing the percentage of cases with direct personal detail disclosure and the number of potential patient matches in registries. The system also incorporates a local memory to distill and reuse expertise from past consultations, enabling subsequent cases to benefit from prior remote exchanges without further data transmission.
