Blockchain based Enhanced Healthcare Framework for Secure Interoperability
Satish Kumar, Saurabh Kumar · 2024
Medical history of patients is sensitive and crucial for the treatment. During epidemics like COVID-19, secure data exchange between hospitals is very important. However, shareability of data with security in existing healthcare system is a big concern. To overcome this, we have presented a blockchain based enhanced healthcare system for secure interoperability. To protect the system from external threats, hospitals are connected to each other with the distributed networks. And to protect the system from internal threats, a hospital is further divided into distributed peers where a peer represents a section or a department of hospital. Identity managers are implemented at both peer and organizational levels to ensure efficient access control. Through simulation analysis, we have found that the reading and writing throughput is improved around 16 % and 25 % with respect to existing method.
