Adoption of Blockchain Technology for Privacy and Security in the Context of Industry 4.0

Abstract

Compared to centralized and decentralized models, distributed models have the potential to dramatically expand the scalability of existing IoT and Industry 4.0 solutions while maintaining participant organizations’ security and privacy. This is partly because participating firms are not required to rely on or trust other services or third parties to manage the data they gather and transfer, out of concern that these parties could misuse the data or, in the worst-case scenario, share it with mass surveillance programs. However, until blockchain technology (BCT) demonstrates its viability as a means of developing security solutions in decentralized, collaborative, and trustless environments, the vast majority of these use cases will struggle to meet the requirements for integrity, immutability, traceability, and notarization. By utilizing BCT, it is possible to eliminate intermediaries, enabling individuals and devices to manage their data independently of third parties and most significantly to achieve a high level of traceability with information flow harmony. This technology enables transaction, transparency, and traceability by enabling for the interchange of historical data. The fundamentals of blockchain are examined in this research paper, along with an investigation of its operation and a discussion of some of its most fundamental aspects and concepts. A concise overview of smart contracts enables us to completely reimagine how network members create and automate transactions. Finally, several IoT and Industry 4.0 application possibilities that leverage blockchain are investigated, as is the blockchain’s future trajectory.

Enhanced Homomorphic Encryption and Dual Blockchain Authentication for Securing Medical Data on the Internet of Things

“…The blockchain can be defined by a communication procedure that can be an architecture related to distributed database logic [19]. The healthcare data is saved in different devices which can be combined composed by nodes in the architecture.…”

Leveraging big data and analytics for enhanced public health decision-making: A global review

“…Ensuring compliance with data protection regulations, safeguarding sensitive health information from unauthorized access (Hodge, et al, 1999;Keshta, and Odeh, 2021;Gostin, 2001). Adoption of encryption techniques, blockchain technology, and secure data sharing platforms to enhance data security and privacy (Liu, et al, 2020;Joshi, et al, 2022;Agyekum, et al, 2021). Variability in data quality, lack of standardization across data sources, interoperability issues hindering data integration.…”

Fundamental pillars for industry 4.0 development: implementation framework and challenges in manufacturing environment

“…Therefore, it is more essential to make changes within established production lines without affecting its impact on customers (Trappey et al, 2017) (Kannan and Garad, 2021). Some of advance technologies such as blockchain (Joshi et al, 2022), artificial intelligence (AI) (Munim et al, 2020) (Goyat et al, 2019b), machine learning (ML), smart city and Internet of things (IoTs) (Singh et al, 2022a) have been playing crucial and trajectories role over last decade with imperceptible overlap in their own. In the form of data and their processing, there is a more evident association among all technologies.…”
