Internet das coisas, blockchain e contratos inteligentes aplicados à saúde

Abstract

The Internet of Things aggregates devices able to capture information and interfere in the environment, acting in systems of different domains of application, such as healthcare. These systems need a layer of security to guarantee, among other characteristics, the irrefutability, anonymity, and integrity of the manipulated data. In this sense, an integration with a blockchain, through smart contracts, would meet this need. This chapter, therefore, presents current research using IoT, blockchain, and smart contracts in healthcare. The details for using these technologies in healthcare, the technical challenges and the consensus protocols involved in the main applications will be discussed. This chapter presents a practice that applies knowledge in the health supply chain, building a decentralized application (DApp) that monitors the temperature of vaccines during their storage. In the end, it offers an informative guide that allows participants to design training in this area, including practical exercises.
