Abstract
The Electronic Health Record (EHR) systems provide health information
about patients. Data security, integrity, and management of EHR are crucial problems.
Records can be modified and altered by different stockholders as the different users
may be using them in more than one form. Medical records management is a suitable
application for blockchain-enabled records that can be stored, tracked, and managed by
all the transactions to prevent fraudulent activities. A novel framework has been
presented here in the healthcare sector by using the blockchain concept. The major goal
of this article is to implement BlockChain for electronic health records (EHR), and its
decentralized approach eliminates the chance of a single point of failure, making the
system robust. The proposed work also covers the extensible problem faced by
BlockChain in common with the help of an off-chain repository of the data. The results
indicate that computing is much more secure and free from a scam than the traditional
health record system. Finally, the proposed approach suggests scenarios such as EHR
where the introduced approach should prove adequate.
