How does the book discuss the role of technology, such as blockchain and 5G networks, in addressing privacy and security concerns in the IoT era, and what are the potential benefits and drawbacks of these technologies?

The book discusses how technologies like blockchain and 5G networks can address privacy and security concerns in the IoT era. Blockchain is highlighted for its potential to provide a tamperproof audit trail of supply chain events and data associated with a product life cycle, enhancing trust. However, it doesn't solve the trust problem associated with the data itself. 5G networks are praised for their reliability, ultra-low-latency, and high bandwidth, which can mitigate pandemic-related challenges. The potential benefits include improved data security and efficiency in operations. Drawbacks include challenges in GDPR compliance, potential intrusiveness, and the complexity of integrating these technologies.
