ABSTRACT:

Cloud computing plays a vital role in modern data storage and management, offering scalability and flexibility for users. However, increasing reliance on cloud services raises serious data security concerns, such as breaches, unauthorized access, integrity issues, and cyberattacks. Traditional methods like encryption and identity management often fall short in fully addressing these risks. Blockchain technology, with its decentralized, tamper-resistant nature, offers a promising solution for enhancing cloud security. This paper explores how blockchain’s features—decentralization, immutability, transparency, and smart contracts—can address issues like data integrity, unauthorized access, and secure sharing. It also examines real-world applications in cloud storage, identity verification, and data privacy. While integration faces challenges like scalability, performance, and regulatory compliance, blockchain presents a transformative approach to secure cloud environments. The paper concludes by highlighting future potential and the need for continued research to address current limitations.
