Abstract: Secure data sharing is the most challenging and essential problem to be addressed in cloud systems. In traditional works, various blockchain and cryptographic approaches are deployed for enabling secured data storage and retrieval in cloud platform. However, the conventional frameworks require third-party entities for user authentication, data verification, and identity management. In our proposed work, an intelligent blockchain-based cryptographic data security (IBCDS) scheme is developed, where no third-party auditor is required for authentication and validation for secured data sharing over cloud systems with minimal overhead and computational complexity. In IBCDS, blockchain acts like user management system that stores information of each cloud user in the form of transactions by assuring reliability and integrity of each transaction along with tamper-proof. During analysis, IBCDS mechanism is evaluated and compared by using different parameters where security performance is improved to 99%, time complexity reduced to 98%, and overall throughput is maximised to 99%.
