A Health Information Exchange Based on Block Chain and Cryptography

Abstract

This study will propose a HealthCoin scheme that can provide hospitals, doctors and patients to exchange health information with each other. The HealthCoin also is a transaction certificate for health information exchange. The study is based on block chain and cryptography and there are three rules: hospitals, doctors and patients that are nodes on our proposed block chain scheme. However, medical records relate to the privacy of patients and medical institutions must not only have the electronic health information exchange mechanism, but also pay more attention to the network security and patients’ data protection. So there was a third-party fair association to integrate the health information exchange mechanism and many associations want to be third parties fair. As a result, many hospitals or medical institutions do not know who to integrate or exchange with. Therefore, the project will use block chain technology and cryptography to solve the problem of third-party fairness and exchange health information with each other using HealthCoin.
