Abstract: In this emerging technological era, digitisation becomes unavoidable and dominates our daily lives. However, in order to ensure the privacy of the data, it must be securely stored and exchanged. Blockchain is commonly employed in the administration of patient health information. In this paper, a health information exchange and secure storage system based on the private blockchain is presented. The network is hosted by individual hospitals to enhance the security of their client's information. The system includes a Central Healthcare Provider (CHP), which manages the patients' healthcare information by utilising this trustworthy system, doctors can access patients' historical data while maintaining patients' privacy. Additionally, a mechanism for symptom-matching is proposed for patients and doctors. It enables two distinct patients/doctors to share their experience with each other. This can be accomplished by performing a mutual handshake between two entities and generating a key to secure communication during the session.

Keywords: blockchain; central health provider; healthcare; symptom-matching; tamper resistance.
