Due to the high need for unstructured data storage nowadays, cloud storage technology is crucial for storing and accessing data on remote servers for better growth. Due to a lack of security, there are several privacy leakage issues in use today's cloud storage services. There is a potential that unauthorised users might misuse the data by deleting or altering the data that already exists in the data repository because, in general, all cloud servers attempt to store and access the data under a centralised storage location. This inspired me to suggest this essay, which incorporates fog computing to completely secure the data. Here, we created a multi-level privacy protection system where each and every portion of a cloud server that is divided into pieces is viewed as a fog node The data will be split up into several chunks at first, and each block is individually and securely deposited into a fog node. Here, the data that is saved on the cloud server was encrypted and decrypted using the block chain technology. We ultimately arrived to the conclusion that our suggested SBBS is effective at protecting cloud data from unauthorised user access by running several experiments on our proposed model, and if this is launched in cloud servers, there will be significant security for the distant data.
