- Abstract
In this thesis, we analyze the challenges of using and sharing electronic health information exchange (HIE) in hospitals and clinics. In Canada, there is a lack of HIE platforms that provide interoperability for hospitals and other medical institutions across the country. In this research, we explore a potential use case of utilizing blockchain technology as a tool to facilitate better HIE between users involving patients, doctors, and researchers. Our proposed proof-of-concept evaluates the impact of using and implementing smart contracts to assist in automating the digital identity and access management of medical data via the use of public-key cryptography. In addition, we apply Shamir's secret sharing scheme by distributing the public keys of users to safeguard better the identities and data of users in our system. We evaluate our proposed solution in the context of scalability, complexity, and efficiency, as well as comparing our approach to other blockchain-based healthcare solutions.
