Adopting healthcare information systems and electronic health records (EHRs) result in various benefits for the healthcare sector such as realtime decision support and availability of critical medical information.Despite the many benefits that are associated with adopting EHRs, the transition to digitally stored and shared records hold various challenges regarding the privacy and security of medical data.This paper aims to offer an alternative design to manage EHRs with blockchain technology, where the emphasis of our design lies in adopting blockchain and smart contracts as a permission management database.We present a general overview of the architecture of our blockchain-based EHR permission management system and describes the value exchanges that take place between the different parties participating in the EHR ecosystem in which our blockchain-based system is to be implemented.1
