Abstract
Electronic Health Records (EHRs) are designed to manage the complexities of multi-institutional and lifetime medical records. As patients move among providers, their data become scattered across different organizations, losing easy access to past records. The records should be kept in digitized format with required protection from unauthorized access. There are many schemes to solve these issues, which includes central server based systems, cloud based systems and blockchain based systems. The trending solutions are cloud based and blockchain based solutions. Even though cloud based system provides much scalability through various mechanisms, it is trusted as a secure system in which data may be corrupted with or without the knowledge of cloud provider. The blockchain technology overcomes the barrier of trusting an agent. But the blockchain based system lacks scalability and requires huge storage space. The proposed system, HealthChain, provides a secure health care record management system with scalability and low storage space. HealthChain divides the whole system into regions and uses two kinds of blockchains, Private Blockchain: for intra-regional communication and, Consortium Blockchain: for inter-regional communication. The proposed system utilizes a consensus mechanism for mining.
