Integrating technology in Identity and Access Management (IAM) for cloud computing has
significant advantages. It ensures the security and integrity of identity information through a
ledger, enhancing user privacy and control over personal data. Contracts automate identity
verification, reducing the need for centralized authorities. This approach improves access
management transparency, accountability, and audibility, creating a robust and user-focused
framework for cloud computing (Vanmaele, 2019).
Vanmaele (2019) states that integrating blockchain into IAM enables transactions without
intermediaries. Merging blockchain with IAM in cloud computing shifts to a model that enhances
resilience and security while reducing the risk of data breaches thanks to blockchain’s
cryptographic integrity.
Blockchain is revolutionizing digital identity and access management within cloud computing. It
provides a ledger that cannot be altered or tampered with easily. This empowers individuals to
manage their identities without relying on intermediaries while simultaneously improving security
measures and mitigating risks associated with centralized data storage. The inherent security
features of technology ensure that identity records remain tamper-proof, which in turn fosters trust
and privacy (Habiba et al., 2014).
According to Graupmans (2021), blockchain can potentially significantly transform IAM in cloud
computing. It suggests replacing centralized systems with decentralized networks to enhance
security and prevent identity theft and fraud. Incorporating encryption and smart contracts within
technology can address privacy concerns, while shared ledgers facilitate transparent tracking of
identity attributes. These developments indicate a shift towards transparency and user-controlled
data.
Blockchain’s introduction into IAM for cloud computing holds potential. It introduces a
decentralized structure that improves security and transparency. It effectively mitigates risks
commonly associated with IAM systems, such as data breaches and account hijacking.
Implementing Self Sovereign Identity (SSI) on blockchain allows individuals to have control over
their identities. However, there are still challenges in terms of scalability, integration, and
compliance with regulations (Harshavardhan et al., 2018).
Blockchain revolutionizes IAM in cloud computing by introducing a decentralized framework for
managing digital identities. It moves away from centralized systems and provides an immutable
ledger that enhances security and simplifies identity verification processes. This technology aligns
well with the distributed architecture of cloud computing, creating a foundation for IAM
(Vanmaele, 2019).
According to experts like Marc Vanmaele and researchers such as Habiba, Masood, and Shibli,
blockchain is considered a game changer in IAM as it offers a model that puts users at the center.
While cloud-based IAM systems are known for their flexibility and scalability, they are susceptible
to points of failure.
Finally, the blockchain’s ability to decentralize, maintain immutability, and provide transparency
has the potential to address these risks effectively. It can establish a cloud-based IAM system that’s
not only more secure and efficient but also gives users greater control over their information
(Vanmaele, 2019; Habiba et al., 2014).
