Enhanced Privacy Setup for Blockchain-Enable IoT Devices Using Multi-Factor Authentication

As the number of Internet of Things (IoT) devices keeps growing, security has become a major concern. With trade-offs like complexity and scalability, maintaining privacy in the system is a highly desired characteristic. This work presents an architecture for the management of IoT devices with Hyperledger Fabric. We incorporated our system with blockchain and Closed Circuit Television (CCTV) surveillance camera at a rental property. When new renters arrive, the CCTV security camera automatically reroutes its stream. We implemented multi-factor authentication via push notifications and web tokens to enhance security between renters and property owners. One of our contributions is an effective architectural framework that makes use of multi-factor authentication and key invalidation circumstances. Our proposed scheme enhances the security of IoT devices with blockchain technology and mitigates the risk of a single point of failure, providing a robust and reliable solution.
