Blockchain-Based Framework for Enhancing Data Security in IoT Systems

Article investigates a blockchain-based framework for enhancing data security in Internet of Things (IoT) systems. Employing a qualitative research methodology, the study explores the integration of blockchain technology to address vulnerabilities in IoT ecosystems, including data breaches, unauthorized access, and the challenges of centralized data storage. By analyzing existing literature, case studies, and expert opinions, the research identifies blockchain's potential to provide secure, decentralized, and immutable data management in IoT systems. The findings highlight blockchain's ability to enhance data integrity through distributed ledgers, ensure data confidentiality via advanced cryptographic techniques, and improve accountability with transparent transaction records. Additionally, the research underscores the scalability challenges of blockchain in IoT, proposing hybrid architectures that combine private and public blockchain systems to optimize performance and resource utilization. Real-world applications such as smart home systems, healthcare IoT, and industrial IoT demonstrate the practical viability of blockchain integration for improving security. The study also emphasizes the importance of regulatory frameworks and cross-industry collaboration to address interoperability and privacy concerns. This research contributes to the growing discourse on secure IoT infrastructure by presenting a comprehensive blockchain-based security framework. The proposed framework offers actionable insights for IoT developers, researchers, and policymakers seeking to enhance trust, reliability, and resilience in IoT systems.
