Abstract:	With the advancement and popularization of science and technology, much research explores the provision of health care services or health management with the assistance of information technology in addition to traditional clinical diagnosis. Personal Health Records (PHR) are available for personalized health record information in the autonomous management system. The personal health record system is to improve disease management or strengthen personal health management. However, users are concerned about the safety and confidentiality of PHR in healthcare systems. In 2008, the blockchain architecture was proposed by Satoshi as a peer-to-peer network architecture that contains a Distributed Ledger Technology (DLT). In this study, we proposed a blockchain-based PHR system using the homomorphic encryption to improve the privacy and security of the users. It allows a third party to perform operations on the ciphertext which can be retrieved correctly later, while the privacy and security of the nodes on the chain are ensured and provided for multiple users to protect the security of their information.
