RBAC-HDE: On the Design of a Role-based Access Control with Smart Contract for Healthcare Data Exchange

Abstract

Recently there have been many emerging innovated Blockchain applications in various sectors including healthcare. In this paper, we propose a role-based access control system, namely, RBAC-HDE, which harnesses the powerful features of Blockchain such as immutability and decentralization, in order to facilitate secure data exchange for healthcare. We design and implement an Ethereum-based testbed to demonstrate the basic idea. Our preliminary results have shown the feasibility and potential of this approach.
