User-Controlled, Auditable, Cross-Jurisdiction Sharing of Healthcare Data Mediated by a Public Blockchain
Xiaohu Zhou, Vítor Jesus, Yonghao Wang, Mark B. Josephs · 2020
We tackle the problem of sharing eHealth data across different jurisdictions. As a general rule, and due to the sensitive nature of the information, different national regulations impose severe limits on what can be exchanged, even in case of emergencies. Furthermore, different systems in different jurisdictions do not communicate. We propose BRUE as a scheme that allows eHealth data to be securely exchanged, with the data subject always in the position of mediation. We combine several technologies, namely, Blockchain, OAuth and User-Managed Access, and concept Receipts, to achieve our aim.
