1	A Review of Blockchain Based Identity Management for Cloud, Fog, IoT and Enterprise Systems Anant Wairagade, Nikhil Gupta, Vijay Govindarajan Abstract - In the realm of technology, the need to validate and secure digital identities among different environments, including cloud, fog computing, Internet of Things (IoT), and enterprise systems, is more than ever. Traditional identity management systems, though aiming to provide the solution, suffer from data breaches because of dependence on centralized architecture and further encounter challenges. The incorporation of blockchain into identity management gives a decentralized, tamper-proof ledger along with robust cryptographic protocols that improve the security challenges of authentication, authorization, and privacy. This article reviews the existing blockchain based identity management methods in the field of cloud, fog computing, IoT, and enterprise systems. A critical analysis was performed which highlighted these methods strengths in providing security while pointing out limitations in the form of energy, latency, communication overhead, and scalability concerns. Furthermore, existing use cases of blockchain platforms that employ identity management solutions such as IoTeX, IOTA, Neblio, Kaleido, Sovrin, SelfKey, Civic, VerseOne are also explored, and a comparison is made between them. Moreover, an evaluation is performed under specific criteria to show which systems work efficiently under specific criteria. On the basis of evaluation of existing literature and use cases, several challenges came to light, such as lack of scalability, performance issues, and compliance with the regulatory framework. Future directions provide insights into a possible improvement, such as improving scalability and performance, and the use of quantum-resistant algorithms to improve security and enhancing interoperability standards to address existing challenges. Overall, this study gives a detailed roadmap for researchers and identity management practitioners which aim to develop efficient blockchain based identity management systems, balancing strong security and performance while keeping compliance in evolving landscape of IoT, cloud, fog computing and enterprise systems.
