The rapid development of cloud computing has been greatly aided by the popularity and power of cloud storage. Nonetheless, there are still serious security incidents that, as a consequence of malicious attack and management negligence, cause widespread sensitive data exposures at the cloud storage tier. To preserve the privacy of cloud data, this study created (CSSM). By combining data dispersion with dispersed storage, CSSM was able to provide encrypted, chucked, and scattered storage, preventing data intrusions at the storage layer. In addition, CSSM used a system of management levels and combined user passwords with secret sharing to avoid any unauthorized access to cryptographic materials. The experimental results show the proposed method can successfully store enormous amounts of cloud data without introducing a substantial latency cost, and is also suitable for securing data at the storage layer from leakingCloud storage today depends entirely on large storage providers. Such storage providers function as untrusted third parties that process data for storing, sending and receiving data from an entity. This style of system has many problems, such as high operating costs, software quality and data security. In this paper, we present a model of a multi-user access control system for databases that use blockchain technology to provide stable, distributed data processing. The system allows the data owner to upload the data via a web portal. So, the user who has the secret key to the particular data that has been uploaded to Cloud in encrypted form can only access the folder. Eventually, the system promotes data privacy by maintaining the immutability of the blockchain by processing it in the cloud. We have proposed a secure, blockchain-based data storage and access control system to increase the security of cloud storage.
