Abstract:
This article investigates the use of blockchain technology to improve data security in smart buildings, addressing the growing vulnerabilities caused by the interdependence of IoT devices. The paper thoroughly examines the existing issues and limitations of traditional security solutions in smart buildings. Through a comprehensive literature review and qualitative analysis, this research identifies decentralisation, cryptographic mechanisms, transparency, and distributed ledger technology as core features of blockchain that can significantly improve data security and confidentiality in smart buildings. This paper qualitatively assesses the importance of the identified blockchain features which enhance data security in the context of smart buildings aiming to create a secured system environment that enhances data security and prevents unauthorised access. The methodology employs a qualitative approach, including semi-structured interviews with industry experts and data analysis, to validate the effectiveness of the identified blockchain features. According to the findings, blockchain not only improves data transaction security yet nurtures a resilient infrastructure to meet the changing demands of smart building management. The study contributes to academic literature and provides practical insights for professionals looking to adopt blockchain-based security solutions in smart buildings, with implications for legislation and future research paths.
