Data Security in Healthcare Using Blockchain Technology

Data are the most important assets in all kinds of industries, as every organization is moving to cloud storage but still data security is a challenging one in many fields. One of the most important fields is Healthcare because it handles with most sensitive information. Since the data in healthcare includes patient's medical information, prescriptions, their medical insurance, etc. Due to the sensitive nature of the information stored within the EHRs(Electronic Health Records) data security is very essential. Blockchain is a technology that is developed based on two major mathematical concepts such as hashes and cryptography. Blockchain stores data as an immutable ledger that is duplicated and shared throughout all networks in a delegation from a central authority. In this paper, we provide how data can securely be stored and accessed in healthcare. Since one node blockchain is often used for worldwide electronic health records (EHR) it will store and manage patient data in a very verifiable manner & blockchain can be in public gettable in real time by anyone within the aid service supplier chain. This paper aims to discuss the issues in the existing systems and solutions to the challenges of using blockchain technology.
