Abstract
With the rapid evolution of cloud computing and the growing concerns over identity theft and unauthorized access, securing user identities has become critical. Traditional identity management systems (IDMS) often face challenges such as centralization, lack of transparency, and vulnerability to breaches. This paper proposes a blockchain-enabled identity management system designed to enhance security, compliance, and user privacy in cloud environments. Utilizing distributed ledger technology (DLT), smart contracts, and cryptographic protocols, the system ensures decentralized authentication and immutable audit trails. The proposed framework is evaluated against key security and compliance benchmarks. Comparative performance metrics and architectural analysis reveal improved resilience, scalability, and regulatory alignment compared to legacy IDMS.
