Cloud Storage Security Based on Blockchain: A Survey

Blockchain technology and cloud storage security have advanced significantly as a result of privacy and data security concerns. answer the growing concerns about data privacy and safety. Cloud storage can improve data integrity and secrecy by utilizing Blockchain's decentralized and irreversible capabilities. Blockchain offers a more reliable option that reduces the chance of theft, even though encryption techniques still provide some security. Access control, transparency, and data integrity are all intended to be improved by this integration. The risks of typical cloud storage are discussed in this paper, with a focus on file uploads, which are prone to theft and unauthorized access. We investigate how data integrity and secrecy in cloud storage systems might be improved by blockchain's decentralized and irreversible properties. Our approach entails a thorough analysis of the body of research on blockchain applications in cloud storage, with a particular emphasis on encryption, decentralized storage, and access control techniques. The findings show that by using tamper-resistant techniques that lower the risk of theft and improve data integrity, blockchain technology offers a more dependable substitute for protecting cloud storage. However, there are hazards involved that cloud service providers and specialized blockchain security companies need to consider, including issues with scalability, regulatory compliance, and implementation difficulty. Finally, our results demonstrate the exciting new directions and insights that blockchain-based cloud storage security solutions present. By offering insights into the application of blockchain technology to improve data integrity, transparency, and access control, this research adds to the body of knowledge already in existence and helps scholars and practitioners in their search for blockchain-powered secure cloud storage solutions.
