Digital Health Data Supervision using Blockchain in Ethereum Testnet

Abstract

In current systems, patients’ data and information that are critical are scattered across different systems and institutions. Due to this, non-trivial data is not handily available or accessible when needed. Such problems related to patient healthcare data can be handled effectively using blockchain solutions. This ever-increasing data leads to problems in managing patient information within clinics and hospitals. Our project aims to create a hash for individual patient health information blocks. It would also permit patients to keep their identity secret and reveal the necessary information to third parties at the same time. The access permissions and time limit for data sharing can also be controlled by them. A platform called "Ethereum" will be used as the blockchain technology to create an application that will store patients’ data securely in the blockchain. A contract-based language called "Solidity" will be used to bind each patient’ data with their unique addresses to the blockchain and to provide functionalities to the application. A browser-based user-interface will be developed to be used by the users that will connect with the blockchain internally.
