Abstract

There is an increasing adoption of blockchain technology over
different environment for leveraging security features. After reviewing
existing blockchain-based approaches, it is noticed that there is still a
large scope of improvement towards data security using blockchain.
Therefore, this paper considers a case study of healthcare facilities,
where the sensitive information of patient are required to be accessed as
well as stored using a novel blockchain-based approach. The proposed
system contributes towards developing a novel access control policy as
well as a cost-effective authentication policy using a simplified hashing
scheme. The prime contribution of the study is to prove that without using
sophisticated encryption, it is feasible to integrate blockchain with
hashing method for offering higher degree of threat mitigation measures
by proposed system.
