Access Control of Healthcare Data using Blockchain Technology

Abstract

The innovative development in the internet of things is not only giving rapid growth in the development of efficiency of new technologies but also giving a threat relative to the integrity and confidentiality of data. So, it requires security, privacy, data integrity, confidentiality, authentication and authorization which is provided by the Blockchain Technology. This paper mainly represents access control mechanism for different nodes in the smart healthcare environment. For this it uses multiple access control smart contracts. Here the smart contract is implemented using Ethereum Smart Contract increasing the confidentiality and integrity of data by providing Authentication, Access control, Authorization for the management of data sharing and storage of data. Here the smart contracts will provide Node Authentication and authorization of each device, based on the registration to provide the data security which is missing in other Internet of Thing’s applications.
