A Granular Approach to Secure the Privacy of Electronic Health Records Through Blockchain Technology

The method of storing data in traditional Electronic Health Records (EHRs) becomes even more obsolete when it has to undertake data from more than one institution. This problem is bigger than it seems as, most of the times the patients' medical data is scattered among various Healthcare Centers. Also, these multiple and inconsistent health records are almost never reviewed which further makes them unreliable. All this can be achieved by implementing the Blockchain Technology into the traditional Electronic Health Records. We propose a blockchain technology based Electronic Health Record portal for patients, doctors, and other users to provide temper proof, secure, and efficient access to health records while maintaining the privacy of patient’s health records. The aim of this paper is to deal with the various needs of patients, doctors, and third parties, as well as to see how the system could resolve privacy and security issues in the healthcare industry.
