IoT Data Validation Using Blockchain and Dedicated Cloud Platforms

The Internet of Things world has grown exponentially in recent years, projecting the future toward an increasingly automated reality in which human presence results less and less and decisions about processes are made directly by machines, which exchange information, operating to maximize a goal. Such complex and automated systems pose quite a few challenges from the standpoint of securing cyber-physical spaces, particularly tampering with the data of specific components and/or sensors, which can go a long way in impacting the operation of the entire system and causing damage. This work aims to reduce the possibility of data tampering by using Blockchain systems integrated into cloud platforms for data collection and analysis so that in the case of critical decisions, this information can be verified in a certified way and thus proceed safely. An application case study based on ThingsBoard and HyperLedger Busu technologies was proposed showing how these technologies can integrate and collaborate to achieve effective results.
