Cloud computing is modifying the way many organizations are managing their data, because of its robustness. Privacy concerns come up whenever sensitive data is transferred on to the cloud. A simple method for protecting data privacy of data is to apply certain privacy techniques on data, and then uploading the modified data on cloud. The privacy methods used in existing research shows that privacy violation of data for cloud computing happens by external or internal attackers. In proposed system such issues are solved using various privacy protection methods also this system has three models, which initially have zero trust among them. Multi-level image fusion technique is used for generating a strong and secure key that will be given by the transaction manager to the user whenever required. In this way proposed system will provide much better privacy and security of the data in cloud and provide a better secure access of data.
