Adoption of Blockchain Technology to Secure Electronic Healthcare Record for Efficient Healthcare System

Today, blockchain technology has become one of the most important inventions and unique breakthroughs that have had a significant impact on people and various sectors. Specifically, in the healthcare sector, blockchain shows a promising future in storing medical records on the internet in a secure manner. Through this paper, we are spreading light on the Electronic Health Records (EHR) system, which is based on blockchain technology. As we all know, a blockchain ledger is an immutable, secure, and organized database. Thus, storing medical records of individuals on this ledger will help them to efficiently share documents with their authorized doctors, cloud storage facilities, as well as tamper-proof hash cryptography of data. There are plenty of different architectural approaches to attain this proposed objective. But, the distribution of public keys and private keys is the core system for EHR as it is developed on blockchain. The public and private keys are distributed in EHR to different clients for accessing data, along with that user’s ability to change the rights accordingly from view to edit. Blockchain-based Personal Health Records (PHRs) systems have emerged as the newest thing in patient-driven healthcare.
