Abstract—Cloud computing has revolutionized data storage, offering scalable and flexible solutions for diverse applications. Despite its advantages, significant concerns regarding data security, privacy, and integrity remain. Blockchain technology, renowned for its decentralized, transparent, and tamper evident properties, presents a promising solution to address these challenges. This paper explores the integration of blockchain technology with cloud-based data storage systems to enhance security and trustworthiness. We propose a novel framework that leverages the immutable nature of blockchain to ensure data integrity, confidentiality, and availability in cloud environments. Our research delves into the architectural design, implementation challenges, and potential benefits of the proposed system. Key components include decentralized data management, secure data sharing, and robust access control mechanisms. Additionally, we discuss the integration of smart contracts for automated data governance and compliance. The effectiveness of our approach in safeguarding data against unauthorized access, tampering and data breaches is demonstrated while maintaining high performance and scalability. The proposed framework aims to provide a secure, efficient, and trustworthy solution for data storage in the era of cloud computing.

Keywords—cloud computing, blockchain technology, data security, data storage, smart contracts, decentralized data management, secure data sharing, access control
