A Secure and Efficient Blockchain Protocol for Protecting Electronic Health Records

The proposed architecture eliminates the need for computationally intensive Proof-of-Work mechanisms by using both public and private blockchains to enable peer-to-peer communication between IoT devices and SDN controllers. These systems, however, rely on traditional client/server infrastructures that confront considerable security and privacy challenges, as well as strict compliance with healthcare privacy regulations. For modern health care systems, it is essential to manage electronic health records (EHRs) efficiently. With these challenges in mind, the proposed model introduces a blockchain-based approach for securing authorization and integrity maintenance, scalable and manageable enough to integrate seamlessly with existing healthcare systems. Blockchain and the healthcare sector are explored in this paper, highlighting the features and recent developments of this technology. In conclusion, blockchain plays an essential role in improving health records organization, security, and management, thus making healthcare more efficient and secure.
