ABSTRACT

Cybercriminals are now focusing on the healthcare industry. As a result, many methods are employed to safeguard the confidential information in the healthcare system. Different industries, including industry 5.0, government agencies, banking systems, cryptocurrencies platforms, healthcare, etc., adopt blockchain-based architecture. A new paradigm has been established with blockchain-enabled intelligent Internet of Things (IoT) architecture for secured healthcare systems. Because it is used to securely create, manage, and transmit healthcare data. An enormous amount of generated data, which is called the big data, is produced with the growing use of IoT devices. Artificial intelligence (AI) can be used to assess and forecast real-time data, which is crucial for predicting patient disease. However, smart healthcare system’s data has problems as it is centralised in nature and suffered from different security and privacy-related issues. The newly developed technology, like, the blockchain can solve the problems with the data in smart healthcare. Here the data can be kept on the blockchain in a decentralised format, with some nodes (i.e., servers). It also provides various security properties. It offers immutability characteristics for resource management, authentication, and allowing secure access to the smart healthcare devices of the healthcare system. In this book chapter, we first introduce the architecture of a blockchain-enabled intelligent Internet of Things system for secured healthcare applications (BIoTS-SH). Then, issues, challenges, security requirements, applications of BIoTS-SH have been discussed. Finally, we present a systematic and comprehensive overview of the existing secure blockchain-enabled IoT-based systems for healthcare applications.
