A Blockchain Based Cloud Integrated IoT Architecture Using a Hybrid Design

The Internet of Things (IoT) and its applications are gaining popularity in recent years due to features like ease of use and increased availability of the Internet. We can enhance the efficiency of IoT based systems by adding other advanced technologies like cloud infrastructure and blockchain technology. Through these enhancements IoT applications can be accessed at any time from any place. However, a database is required for storing the information of the application. Cloud infrastructure is an ideal solution for storing IoT based applications as it provides remote services such as storage, computation, and analysis. The major drawback of these applications are their inability to provide security and privacy for data. Blockchain technology helps in overcoming these drawbacks with features like immutability, transparency, and distributed structure. In this paper, a blockchain based cloud integrated IoT application is proposed that can assist to identify intruders through virtual monitoring. The main advantage of this application is that it can operate in areas where manual monitoring is challenging and data is stored in a blockchain-based tamper-free environment.
