Cyber Security and Cyber Resilience for the Australian E-Health Records

Abstract

Cybersecurity is a critical consideration for all users of electronic health records (EHR), particularly for patients. With the advent of Healthcare 4.0, which is based on the internet of things (IoT) and sensors, cyber resilience has become a key requirement in ensuring the protection of patient data across devices. Blockchain offers crypto-enforced security, data immutability, and smart contracts-based business logic features to all the users in the network. This study explores how blockchain can be a single digital option that can address both the cybersecurity and cyber resilience needs of EHR. The effective use lens is adopted to analyze how blockchain can be leveraged to meet cybersecurity needs while the novel use lens is adopted to analyze how blockchain can be leveraged to address cyber resilience needs originating from IoT. Based on the analysis, this study proposes two Hyperledger-based security models that contribute to individual privacy and information security needs.
