MediBlock: A Blockchain-based Architecture for Secure Healthcare System

The existing healthcare domain has numerous components such as sharing of private medical records, medical insurance claims, and exchange of medical products among untrusted stakeholders viz. users (patients, doctors, nurses, healthcare staff, hospitals), and agencies (life insurance companies, pharmaceutical companies). However, the data exchange between different stakeholders of healthcare suffers from issues viz. fraud in the medical supply chain, dependency for coordination and collaboration among its stakeholders, traceability, reliability, security, and privacy of data. To achieve privacy& security of data as well as profitability & trust for all its stakeholders, Blockchain technology in healthcare is an appropriate alternative that proffers a complete scheme that records and shares essential data securely. The encrypted data generated by Blockchain technology becomes immutable. Hence, this research is intended to propose a Blockchain-based mechanism viz. MediBlock addresses the issues related to the healthcare domain by connecting various stakeholders. We further discuss the implications and potential for the actual adoption of MediBlock.
