HEALTH CARE SYSTEM TO BUILT SECURE PAITIENT RECORD BY USING BLOCKCHAIN AND ARTIFICIAL INTELLEGENCE
Data is the new fuel. In almost every sector data is maintained for future sector or domain investigation. This data is used for later information gathering, it can be a confidential data, and it is a system responsibility that data should be reliable and secure. knowledge and data needs to be transferred among various devices, this data transfer is a need to generation. There are many challenges in storing and retrieving this data in secure manner, also data should be available for each user according to their role. A system which is centralized is more prone to system halt. To protect this scenario and other potential hacks, block chain can be used. Blockchain uses consensus technology in which all nodes validates the nodes and changes which protect from any changes to the existence data. In case of clinical management is consensus and proof of work can protect the data, along with that in many situation there is a need of data mining so that instead of reliving on current dataset, historical dataset can be used to gain new knowledge and to find hidden pattern, in such scenario data gets exposed to other uses, this kind of data privacy concern and solutions are also addressed in this paper. It is observed that Block chain technology in health care system is not only more secure but also has less time and cost complexity over traditional health care data management system .
