A Blockchain-Enabled Data Privacy and Governance Framework for Multi-Cloud Environments

Abstract: Multi-cloud architectures have been selected by industries today to achieve enhanced scalability, resilience and flexible operation capabilities and non-vendor lock-in. Organizations can boost their system uptime and service performance by spreading their computing tasks and storage needs across multiple cloud service providers; however, this approach causes major difficulties for organizations because they need to maintain uniformity in their data control processes, protection of personal information, and auditing procedures, and their ability to meet legal requirements. The research investigates traditional centralized governance systems because they do not work effectively with their existing systems of access control systems inside multiple cloud environments. The study creates a blockchain-based system that protects data privacy rights and establishes governance standards that apply to multiple cloud computing environments. The proposed architecture uses a permissioned blockchain system combined with smart contracts to create unchangeable governance rules and permanent audit trails, while Attribute-Based Encryption (ABE) controls access to sensitive information through precise security measures. The system implements off-chain storing solutions in order to achieve both. performance enhancement and efficient operations, whereas compliance monitoring system. conducts automatic evaluations that comply with the regulations of both GDPR and CCPA. The study aims at developing a decentralized system of governance that is secure and transparent and offers wide multi-cloud management systems.
