Abstract:
Blockchain have been an interesting research area for a long time and the benefits it
provides have been used by a number of various industries. Similarly, the healthcare
sector stands to benefit immensely from the 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 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 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 the blockchain technology in general via 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.
