Advancing Security and Data Protection for Smart Home Systems through Blockchain Technologies

Internet of Things (IoT) systems are becoming ever-present in our lives and the demand recently increased with the explosion of external services offered by healthcare, smart city or smart home providers. However, the connection of private IoT-driven smart home systems and passing data to these external services can pose significant privacy issues, such as information theft or attacks to control, monitor, or harm personal resources. In our paper, we address the identified security issues through a comprehensive architecture based on blockchain technology, namely the Hyperledger Fabric platform. We underscore the value that a permissioned blockchain brings in addressing performance issues both architecturally and through fog computing, and propose a pipeline to mitigate known security threats through static and live monitoring techniques.
