Blockchain-enhanced internet of thing networks for data privacy

Abstract

The Internet of Things (IoT) continues to revolutionize industries by interconnecting billions of devices, but this growth comes with critical challenges related to data privacy and security. Traditional centralized systems for managing IoT data are prone to cyberattacks, data tampering, and breaches, raising concerns about user privacy. Blockchain, a decentralized, tamper-resistant technology, offers a promising solution to these challenges. By integrating blockchain with IoT, data integrity can be ensured through transparent, immutable records. This paper examines how blockchain can enhance IoT networks by improving data privacy, security, and scalability. Case studies from blockchain-based IoT implementations and mathematical models for transaction time and network efficiency are explored.
