Leveraging Blockchain Technologies for Secure and Efficient Patient Data Management in Disaster Scenarios

This paper offers a proof-of-concept system for patient drug prescriptions, utilizing blockchain technology to minimize the sharing of patient data between hospitals and pharmacies. Ensuring security and privacy guarantees is crucial for adopting healthcare management systems, with specific data protection requirements mandated by regulations like the General Data Protection Regulation (GDPR). This work emphasizes the drawbacks of traditional centralized electronic healthcare systems. To minimize data sharing while maintaining patient data confidentiality, we leverage the Hyperledger Fabric blockchain to establish private data channels and incorporate client identity query features. Our approach demonstrates effective monitoring, prevention, and management of potential disasters arising from centralized systems, which pose a single point of failure risk for servers housing sensitive patient data and can compromise the confidentiality of such data.
