Abstract
Today, information security world is witnessing frequent attacks on electronic records by the naive and professional hackers and crackers. Security of Patient’s Electronic Medical Record (EMR) in Hospital Management System is of paramount importance and so warrants immediate attention. In this research work, BlockChain containers running on multiple ports are proposed to be used for holding patient’s medical records. To perform this task effectively, a BlockChain framework named as “Medichain” was developed from scratch that contains all basic functionalities of a BlockChain to secure patient’s data. Each block of the BlockChain keeps a list of records of patient details. Users would be provided with an option of uploading the file containing the list of records as a JSON file, in a decisive, distributed and decentralized network. The proposed BlockChain Algorithm, consisting of cryptographic hash of the records, proof of work and a Merkle tree formulation, were simulated in Python. Results have been positive and encouraging.
