Ontology-Based Access Control Framework for Smart Building IoT Devices

Abstract

Smart buildings with a large number of installed IoT devices require access control systems to manage access to IoT devices by a large number of people. However, the design and implementation of access control systems for each building tends to be very complex due to the large number of devices and users to be managed. To solve this problem, this paper proposes an ontology-based access control framework with the capability to automatically construct IoT systems with access control functions in smart buildings. This paper also proposes a new access control scheme using web ontologies based on role-based access control (RBAC) to reduce the administrative burden. We have implemented a prototype system with access control features at the Minoh Campus of Osaka University using the proposed framework, and evaluated its effectiveness.
