Blockchain-Enabled Smart Healthcare Systems Using IoT

Abstract

A healthcare system is the medical platform through which patients get better treatment. Several hospitals and doctors are linked together through this platform in a hierarchy and treat the patient easily. In view of the COVID-19 pandemic, it is a very challenging task to treat the patients physically; therefore, there is a need to redevelop the healthcare system to fulfill the modern demand. The state of the art of this scheme is to provide remote treatment facilities and build a secure online system. Blockchain technology combined with IoT provides the solution through its vital features of transparency, immutability, decentralization, and trust-less environment. IoT devices capture the patient health status and process it and send to blockchain; therefore, information sharing between devices, hospitals, and doctors are at risk and need to provide security. Using key management scheme in smart contract to ensure integrity of data, this scheme provides better treatment at cheap cost as well as efficiency and security compared to traditional healthcare systems.
