Secure Blockchain-Based Consumer Electronics Platform for Smart Homes with Efficient Access Control and Performance Evaluation

Abstract

Blockchain technology has emerged as a pivotal solution in contemporary digital ecosystems, addressing challenges ranging from supply chain management to the preservation of data integrity. One prominent application domain is consumer electronics, where smart homeowners increasingly rely on interconnected devices to access services in a seamless and efficient manner. While these technologies significantly enhance convenience and quality of life, they also introduce critical security and privacy concerns due to data sharing, unauthorized access, and potential cyberattacks. Addressing these challenges requires robust and reliable security mechanisms that ensure trust and transparency. This study proposes a smart and secure blockchain-based framework tailored for consumer electronics platforms, with a primary focus on identifying potential security threats and mitigating them through appropriate blockchain solutions. A set of practical case studies is presented to demonstrate how blockchain can enhance secure service access while maintaining data authenticity and resistance to tampering. The proposed framework is implemented and evaluated using a private Geth network, enabling controlled experimentation and performance analysis. Performance evaluation primarily focuses on the time required for data loading, retrieval, and block access operations. Experimental results indicate that the proposed Blockchain-Based Consumer Electronics Store (B2CES) exhibits a steady and linear increase in processing time as the number of items scales from 1 to 500, ranging from 0.10 seconds to 8.60 seconds. This performance demonstrates improved efficiency when compared to existing approaches, which exhibit a sharper increase from 0.38 seconds to 9.29 seconds for similar operations. Furthermore, block access time for a set of 500 items is reduced to 7.12 seconds in the proposed framework, compared to 9.29 seconds in conventional implementations. These results confirm the effectiveness of the proposed blockchain solution in achieving enhanced security with reduced computational overhead.Blockchain technology, Consumer electronics, Smart homes, Data security, Access control, Performance evaluation.
