A Use Case in Cybersecurity based in Blockchain to deal with the security and privacy of citizens and Smart Cities Cyberinfrastructures

In today Smart Cities, the automation strategy based on massive IoT devices deployment to gather Big Data to get insights into city behavior to improve its services. The Smart IoT devices interconnected to the Cyberinfrastructure in a Smart City can be exposed to security threats. To overcome failures and Cyberinfrastructure hacker's attacks, surveillance systems to monitor every citizen activity, compromise their privacy rights. We propose in this paper a use case where Blockchain is a promise to conciliate security versus privacy. Moreover, we discuss how we can start implementing a control access system integrating Blockchain, and we discuss benefits and challenges briefly.
