Abstract

Blockchain is an engrossing research field area to introduce in the healthcare sector due to its security, privacy, confidentiality and decentralization. In Blockchain-based systems, data and authority can be distributed, and transparent and reliable transaction ledgers created. Privacy-enabling approaches for Blockchain have been introduced, such as private blockchains, and methods for enabling parties to act pseudonymously. We explore a set of proposed uses of Blockchain within cyber security and consider their requirements for privacy. We compare these requirements with the privacy provision of Blockchain and explore the trade-off between security and privacy, reflecting on the effect of using privacy-enabling approaches on the security advantages that Blockchain can offer. In this research, we present a framework that will help to reduce the inconsistencies that we have to risk in our everyday lives. The aim of this framework is to implement blockchain on storing healthcare records in a pre-assigned database.
