Patient Health Record Security Based on Blockchain

Abstract

It is necessary to keep the patient’s health history confidential as it attracts various attackers who can steal the patient’s valuable information and can lead to wrong medication which is dangerous for the patients. Healthcare using block chain provides security measures using various algorithms and one of them is consensus algorithm. Block chain is a secure gateway composed of decentralized ledger, when it comes to a specific grant of personalized access. Block chain plays a vital role when it comes to security. In Healthcare Block chain organizes the data so that transactions (i.e. Patient’s record) can be verified. Also, Block chain is decentralized ledger which is distributed in nature and has a vital role in securing the data and transactions. Block chain basically contains records in order and is arranged particularly in a block type structure.
