Using Blockchain for Electronic Health Records

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