Security Barrier against Integrity Based Attacks in Block Chain Health Care

Abstract

Healthcare data has grasp the attention cyber attacker because of the sensitivity of the data. Healthcare data has been the victim of many integrities based cyber-attacks recently. Further, patient’s privacy has been adversely effected by keeping the data in a centralized manner as the data is valuable asset for the patients as well as for the medical staff. For the solution of aforementioned problems, we have addressed block chain as a barrier for integrity based attack son healthcare data stored in the block chain. We have designed Healthcare Block chain with a web-interface to keep the medical records of the patients safe against every integrity based attack and unauthorized access. Clients, patients, medical staff and miners can access the Healthcare Block chain via web-interface. The Healthcare Block chain have been divided into two views: Front End (Miner View) and Client End View. Miners can access the Healthcare Block chain via Front End View for the confirmation of valid medical data transactions. On the other hand, clients, patients and medical staff and access the Block chain for doing medical data transactions, viewing health records via Client End View. These web-based interfaces provided the functionality of accessing the data in a distributed manner. This security mechanism has provided the patient with the right of controlled data sharing with the concerned medical staff. Additionally, it provides the medical staff with the facility of managing the data in a decentralized and secure way.
