Blockchain Technology in IoT Devices and Privacy-Preserving Techniques

Abstract

The rapid proliferation of Internet of Things (IoT) devices and privacy-preserving techniques have brought unprecedented connectivity and convenience to various sectors, ranging from healthcare to smart homes and industrial automation. However, this surge in connectivity also introduces significant security challenges, as IoT devices become prime targets for cyberattacks due to their often inadequate security measures. Traditional centralized security approaches are proving insufficient to mitigate the evolving threats landscape, necessitating innovative solutions. Blockchain technology has emerged as a promising paradigm for securing IoT devices, offering decentralization, immutability, and cryptographic security features.

This paper provides a comprehensive review of the integration of blockchain technology in IoT devices and privacy-preserving techniques. It highlights ongoing research efforts and industry initiatives aimed at leveraging blockchain technology to enhance IoT security. It also discusses emerging trends and future directions in this field, including the integration of artificial intelligence and machine learning for anomaly detection and threat mitigation in blockchain-enabled IoT ecosystems. By synthesizing existing literature and analyzing real-world implementations, this paper contributes to a deeper understanding of the potential benefits, challenges, and opportunities associated with deploying blockchain technology to secure IoT devices. Ultimately, it underscores the importance of interdisciplinary collaboration and continued research efforts to develop robust and scalable blockchain-based solutions that can effectively safeguard IoT infrastructures against malicious attacks in an increasingly interconnected world.
