Improving Home Automation Security; Integrating Device Fingerprinting into Smart Home

Abstract

This paper explains the importance of accessing modern smart homes over the Internet, and highlights various security issues associated with it. This paper explains the evolution of device fingerprinting concept over time, and discusses various pitfalls in existing device fingerprinting approaches. In this paper, we propose a two-stage verification process for smart homes, using device fingerprints and login credentials, which verifies the user device as well as the user accessing the home over the Internet. Unlike any other previous approaches, our Device Fingerprinting algorithm considers a device's geographical location while computing its fingerprint. In our device identification experiment, we were able to successfully identify 97.93% of the devices that visited our Webpage using JavaScript, Flash, and Geolocation.
