【Abstract】Data interoperability in health-care is a problem that has yet to be solved. The key question is how to accomplish data confidentiality, data integrity, user anonymity, drug traceability, and data misuse in the health-care industry, including detecting fake drugs. Blockchain technology combined with smart contracts (Chain code) provides a novel technique to securely store patient medical records. Patients will have more control over their information thanks to Blockchain, and health providers, such as hospitals, will have access to patient medical records held by others. Furthermore, Blockchain in healthcare allows users to check the accuracy of patient health information, drug traceability, conduct immutable medical audits, and maintain data security. In this article, we design a secure decentralized authentication framework for Telecare medical information system using Blockchain (TMIS-Chain). Smart contracts written in the Solidity programming language are used to create the proposed decentralized system. Consequently, the healthcare contracts are compiled using Remix and deployed to the personal Blockchain network. In addition, the security strength of the protocol is verified using a push button tool called Automated Validation of Internet Security Protocols and Applications. Finally, a rigorous performance evaluation is carried out to measure the computational and communication overhead of the proposed system. The results shows that the proposed decentralized authentication framework is secure, efficient, and practically implementable in the healthcare system.
