Abstract: Today, major storage providers are the only sources of cloud storage. These storage companies take on the role of unreliable third parties who handle data in order to transfer, store, and receive data from a business. Numerous problems exist with this system, including excessive operational costs, subpar software, and data security. In this study, we provide a multi-user access control system concept for databases that make use of blockchain technology to provide reliable, distributed data processing. Using a web interface, the data owner can upload the data to the system. As a result, the folder can only be accessed by the user who has the secret key to the data that has been encrypted and uploaded to the Cloud. Actually, by maintaining the blockchain's integrity and consistency while processing it on the cloud, the technology enhances data privacy. We designed a safe, blockchain-based data storage and access control solution to increase the security of cloud storage.
