Cloud computing faces challenges regarding data integrity and security due to its centralized nature. This paper proposes a blockchain-based data integrity management system that decentralizes cloud data storage and ensures authenticity and traceability. By leveraging smart contracts, the proposed system validates data transactions, prevents unauthorized alterations, and provides a transparent audit trail. Experimental results reveal that the system can maintain high levels of data integrity with minimal latency and computational overhead, offering a practical solution to enhance data security in decentralized cloud environments.
