In recent years, the incredible growth and diversity of IoT systems and applications have generated an enormous amount of sensing data which play an essential role in IoT-based smart systems. So far, it has consumed much time and cost to collect these sensing data enough for these intelligent systems, which is the main reason leading to the needs of sharing available data to shorten time-consuming and cost savings for the data collection process. However, there are many challenges in ensuring integrity, security, and fairness in the data sharing process. In this paper, the authors propose a model leveraging the emerging Blockchain technology as an alternative solution to enhance the security of IoT data sharing management in terms of three principal criteria including confidentiality, integrity, and availability. Our prototype on Ethereum Blockchain demonstrates the feasibility of the proposed model.
