Blockchain-Enabled Secure and Smart Healthcare System

Technology has developed over the years, making our lives easier. The healthcare sector has benefited from the advancement in technology, leading to an increase in the average life expectancy of human beings. However, there are several problems with the way the sector functions. There is a lack of transparency in the healthcare system, which results in inherent trust problems between patients and hospitals. There is no guarantee of getting the proper treatment from the hospital for the fee charged. Blockchain integrated with the smart contract is a well-known disruptive technology that builds trust by providing transparency to the system. In this paper, we propose a blockchain-enabled Secure and Smart HealthCare System. Fairness of the two entities, patient and hospital, involved in the system are guaranteed if they behave honestly. Privacy and security of patients' medical data are ensured as well. We have implemented the prototype in the Ethereum platform and Ropsten test network and have included the analysis as well.
