A Blockchain Approach for Health Care Sector to Prevent Fraudulent Activities in Medical Records

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.
