Abstract

This review paper examines the evolving landscape of IoT security through the lens of decentralized blockchain-based techniques. It evaluates how distributed ledgers provide privacy-preserving features for sensitive user data, contrasting these with traditional security models. The authors provide a structured overview of decentralized identity (DID) management, encryption techniques, and access control mechanisms designed to mitigate risks such as unauthorized data harvesting and sybil attacks. By exploring various case studies, the study highlights how blockchain techniques empower users to maintain granular control over their IoT device data. The significance of this work resides in its focus on privacy and compliance, offering a critical analysis of how decentralization can satisfy emerging regulatory requirements for data protection in connected device environments.

Key Findings

  • 1Blockchain-based access control significantly reduces the risk of unauthorized data exposure in IoT devices.
  • 2Decentralized identity protocols are vital for protecting user privacy in heterogeneous IoT networks.
  • 3Encryption techniques paired with decentralized storage mitigate the risks of central data compromise.
  • 4Regulatory alignment is easier to achieve when data logs are verifiable and immutable.
