Data Security in Healthcare System using Blockchain

Abstract

Blockchain is a decentralized ledger that may be used to store a wide range of personal information. Once safe storage is established, data privacy should be protected. Some systems rely on blockchain and good contracts to maintain auditability. Blockchain technology will not check/address a method of securing information. Blockchain technologies, which have just lately gained popularity in the field of eHealth, can aid in the creation of a reliable, localized, and patient-driven record management system. We look at the growing literature and implementations for blockchain-based consent management in the tending system in this study. It claims that they may be used to share medical data in a secure and auditable manner. Furthermore, smart contracts based on the blockchain can make some types of permission and data processing, as well as data access management and analysis, easier. The goal of this paper was to perform a thorough investigation on the potential of blockchain as a method of securely storing health-care data.
