Enhancing IoT Data Security: Using the Blockchain to Boost Data Integrity and Privacy

Abstract

The Internet of Things (IoT) is a technology that can connect billions of devices or “things” to other devices (machine to machine) or even to people via an existing infrastructure. IoT applications in real-world scenarios include smart cities, smart houses, connected appliances, shipping, monitoring, smart supply chain management, and smart grids. As the number of devices all over the world is increasing (in all aspects of daily life), huge amounts of data are being produced as a result. New issues are therefore arising from the use and development of current technologies, regarding new applications, regulation, cloud computing, security, and privacy. The blockchain has shown promise in terms of securing and preserving the privacy of users and data, in a decentralized manner. In particular, Hyperledger Fabric v2.x is a new generation of blockchain that is open source and offers versatility, modularity, and performance. In this paper, a blockchain as a service (BaaS) application based on Hyperledger Fabric is presented to address the security and privacy challenges associated with the IoT. A new architecture is introduced to enable this integration, and is developed and deployed, and its performance is analyzed in real-world scenarios. We also propose a new data structure with encryption based on public and private keys for enhanced security and privacy.

Exploring the Impact of METO Factors with Data Privacy Changes at IoT Systems: A Comprehensive Review

“…Additionally, privacy impact assessments (PIAs) and compliance with regulations influence the identification, assessment, and mitigation of privacy risks. This paper investigated Technological aspects that impact privacy concerns including Security Updates [43][44][45][46] regarding technology adoption and mechanisms of development. technological risks included privacy threats [10,24].…”

EPOPTIS: A Monitoring-as-a-Service Platform for Internet-of-Things Applications

“…In this work, data are directly stored in the BC, which is not efficient, and the evaluation is performed in a simulated environment that is not realistic given the current advances in BC technology. The HyperLedger Fabric (https://www.hyperledger.org/projects/fabric (accessed on 25 March 2024)) BC (HLF) is used in [32] to provide data integrity and storage, also employing IPFS (https://ipfs.tech/distributedstoragesystem (accessed on 25 March 2024)) for distributed storage. This platform consists of four layers (physical, network, middle, application), and the authors have demonstrated its scalability in terms of throughput and transaction time and average latency; however, a limitation is that the integrity verification process is "hardcoded", merely based on BC and HLF, as no SCs are employed.…”
