A Smart Contract-based Access Control Architecture for Telemedicine During Covid-19

Abstract

In the fight against the COVID-19 epidemic that is currently a major global public health issue, social distancing has been imposed to prevent the massive transmission, thus doctors in hospitals have turned to telemedicine in order to be able to monitor their patient notably those suffering from chronic diseases. To do so, patients need to share their physiological data with doctors. In order to share this data safely, prevent malicious users from tampering with it and protect the privacy of patients, access control becomes a fundamental requirement. In order to set up a real-time (Internet of Thing) IoT enabled healthcare system (HS) scenario like telemedicine, Fog computing (FC) seems to be the best solution comparing to Cloud computing since it provides low latency, highly mobile and geo-distributed services and temporary storage. In this paper, the focus is on access control in the telemedicine systems. Our proposal is based, on one hand, the concept of Fog computing to ensure the distributed aspect needed in the monitoring of patient health remotely; and on the other hand Blockchain (BC) smart contracts, in order to provide a dynamic, optimized and self-adjusted access control.

Smart Contract-Based Secure Decentralized Smart Healthcare System

“…The main focus of this paper is on health data storage and security in the DSHS systems. The proposed system makes use of the idea of cloud computing to assure the distributed component required in remote patient health monitoring as well as blockchain-based smart contracts to provide access control that is dynamic, optimum, and self-adjusting (Bekr et al, 2021). The blockchain is a technology of a series of blocks in which each block depicts a series of transactions.…”
