Abstract

This paper proposes SmartMed, a tool that aims to control access to distributed medical data through smart contracts running on a private blockchain. SmartMed promotes access to various digital health systems and their interoperability. It enables secure and agile access to information stored in non-standard and heterogeneous data silos, ensuring compliance with regulations and data privacy laws. Smart contracts ensure the tool conforms to security requirements as sensitive data access transactions are executed and recorded in a blockchain immutable way, providing a complete audit trail for sensitive data access. The demonstration at SBSeg focuses on traceability in electronic medical record systems by integrating them with SmartMed via the OAuth2.0 protocol for authentication and access control.
