Preserving Privacy in a Smart Healthcare System Based on IoT

Abstract

Internet of things (IoT) refers to a new technology made up of many heterogeneous resources that are interconnected, controlled, monitored, and analysed through the Internet. These connected devices and resources are part of the smart environment. Recently, many IT organizations and companies adopted this technology. Today, modern societies are highly dependent on technology information and communications, especially, based on IoT which becomes an emerging IT technology being used increasingly in industry, government and healthcare. In a smart healthcare system based on IoT, there are usually many distributed care units with shared resources. One of the most challenging tasks in a smart healthcare system based on IoT is the preservation of privacy. In fact, protecting personal information from unauthorized persons is considered an essential requirement for many smart systems. The traditional access control models do not support privacy requirements and inflexible. In this paper, we propose a new access control model, called activity and attribute-based access control (ABAC), which can efficiently preserving privacy in a smart healthcare system based on IoT.KeywordsInternet of things (IoT)Smart healthcare systemPrivacyAccess controlAABAC
