Abstract: Identity management is a critical component of cybersecurity, ensuring that only authorized individuals can access sensitive systems and data. Traditional identity management systems, which rely on centralized databases, face growing challenges related to data breaches, unauthorized access, and identity theft. Blockchain technology, with its decentralized, transparent, and tamper-resistant nature, has emerged as a promising solution to enhance identity management frameworks and improve overall cybersecurity.
This paper proposes a novel identity management framework leveraging blockchain technology to address the limitations of conventional systems. The proposed system utilizes blockchain's immutable ledger to securely store and verify digital identities, eliminating the need for centralized databases and mitigating the risk of data breaches and identity fraud.Zero-knowledge Self-sovereign identities (SSI) cryptography a key feature of blockchain, empowers individuals to control and manage their own identity data, granting them the ability to selectively share information with trusted entities without relying on intermediaries. The novelty of this approach lies in the integration of blockchain's smart contracts for automated, conditional access control and cryptographic techniques to ensure user privacy and security. By combining these technologies, the system enables the dynamic issuance of identity verifications, such as multi-factor authentication (MFA) tokens, on-demand, reducing reliance on static credentials and enhancing resistance to phishing and credential theft. This decentralized model not only improves security but also enhances user experience by providing a unified and simplified approach to digital identity management. Through extensive analysis, the paper demonstrates how the adoption of blockchain in identity management can significantly reduce cybersecurity risks, such as unauthorized access, data breaches, and identity theft. The proposed framework promises to redefine digital identity management by providing a more secure, private, and user-centric model, which is essential in the evolving landscape of cybersecurity.
