Abstract

Blockchain has been an interesting research area for a long time and the benefits it provides have been used by several various industries. Similarly, the healthcare sector stands to benefit immensely from blockchain technology due to security privacy confidentiality, and decentralization. Nevertheless, the Electronic Health Record (EHR) systems face problems regarding data security integrity and management. In this paper, we discuss how blockchain technology can be used to transform EHR systems and could be a solution to these issues. We present a framework that could be used for the implementation of blockchain technology in the healthcare sector for EHR. Healthcare systems provide fewer security measures to secure health records. Blockchain is a distributed and decentralized ledger that plays a vital role in securing data and transactions. The aim of our proposed framework is firstly to implement blockchain technology for EHR and secondly to provide secure storage of electronic records by defining granular access rules for the users of the proposed framework. Moreover, this framework also discusses the scalability problem faced by blockchain technology in general via the use of off-chain storage of the records. This framework provides the EHR system with the benefits of having a scalable secure and integral blockchain-based solution.
