Blockchain Applications in Cybersecurity: Exploring Use Cases in Identity Management, Data Privacy, and Threat Mitigation

Abstract

Cybersecurity has encountered significant challenges, including identity theft, data breaches, and evolving threats to cyberspace. The decentralized, immutable, and transparent characteristics of blockchain technology have significantly enhanced its efficacy in bolstering cybersecurity. The application of blockchain in identity management, data privacy, and threat mitigation is examined, indicating it as a technology that addresses vulnerabilities inherent in conventional systems. Their capacity to enhance security, user autonomy, and trust is evidenced by decentralized Digital Identities (DIDs), smart contract-enforced data utilization policies, and blockchain-based threat intelligence systems. Despite its robustness, blockchain faces challenges, including scalability, interoperability, regulatory compliance, and energy consumption. Emerging trends (blockchain integration with AI and ML, quantum-resistant cryptography, etc.) are moving toward innovative solutions to these issues. Furthermore, the overlap of blockchain with zero-trust architectures highlights the utility of blockchain in present-day cybersecurity frameworks. The use of blockchain in finance is emphasized through this study as a demand for industry collaboration, scalable innovations, and a supportive regulatory framework to unleash the potential of the blockchain. A blockchain solution can help fill existing gaps in security strategies and pave the way to adoptive security.
