MedTech Chain Demo: Decentralised, Secure and Privacy-preserving Platform for Medical Device Data Research

Employing blockchain and privacy-enhancing technologies, MedTech Chain promises an authenticated, decentralised, secure, and privacy-preserving environment for the real-time research and monitoring of medical device data. Through its querying functionalities, the platform can provide valuable insights for threat intelligence, medical research and hospital management. To our knowledge, the approach is among the first to employ ϵ-differential privacy in the context of medical device data. The current work details the framework’s functionality and demonstrates a negligible time overhead induced by ϵ-differential privacy to data analysis.
