A Systematic Review on Medical Health Data Management Using Blockchain Technology

Abstract

“Data” is the trending word since last few decades. When it comes to any type of data its security is important. Relating the same, maintaining the medical health data is also very significant. When the medical health data is stored or retrieved from the internet is called as Electronic Health Record (EHR). Many times an EHR can be accessed in an unethical way when it is maintaining through conventional approach. Misuse of the same data can lead to many unavoidable problems. Use of Blockchain Technology plays pivotal role in dealing with such problems. An already proven and completely functional Blockchain Technology based Crypto-currencies are the best examples of how efficient and capable Blockchain Technology is. Peer to peer network is used in Blockchain Technology to store the data. Key features of Blockchain-based network are Public Distributed Ledger or non-centralization, Hashing Concept, PoW which makes Blockchain Technology one of most robust technology and highly recommended to use to store and retrieve the data safely.  Goal of stated work is to study various benefits of Blockchain Technlogy, how an Electronic Health Record (EHR) can be access in a predefined way where the medical health data/an Electronic Health Record (EHR) will remain immutable throughout its existence.
