Preserving the Privacy of the Healthcare, Clinical and Personal Data using Blockchain

Abstract

Objective: The healthcare sector produces more data in every day. The security and privacy of this data are prone to misuse. This work aims to use blockchain technology to create healthcare systems that provide users with privacy, control, and data security. Methods: This study envisages a new method to secure private healthcare data and allows only the patients, doctors, and a few medically equipped persons to access the precious data by incorporating a recognition method, authorization of the user, user access monitoring, verification using digital signature and storing the confidential data in the blockchain. Finding: An elliptical curve (EC) method with a digital signature is used to generate recognition. If permission is granted the hash key will be held off-chain to reduce the burden of checking with the main blockchain. The blockchain 3.0 revolution has conveyed hopes for the healthcare sector. In blockchain 3.0, the multi-party computation protocol provides the healthcare data with the highest level of security and privacy to handle the ownership of the user data to the users and allow them to grant permission to the required personnel. Novelty: The decentralization of the data is done and by using blockchain technology in the healthcare sector, the users will have ownership and the privacy of the precious data can be maintained properly. Also, the user can decide who can access their private data. This proposed work can perform non-monetary transactions on the blockchain, which is extensively used in various sectors like supply chain, video streaming, the internet of things, and non-fungible tokens.
