In most of the organization, database management is the key component in the case of information infrastructure. A two- cloud architecture with a series of interaction protocols for outsourced database service, which ensures the privacy preservation of data contents, statistical properties and query pattern. In place of database management in-house, the computer industries have moved on the latest trend of outsourcing the database. The principle reason is that database is facilitated and handled in cloud server, which is outside the ability to control of data proprietors. In the database management, one of the necessary requirements is to provide security to the database by holding the confidential information, but when the database is encrypted there exist the problem of processing queries. Furthermore enhance the security while ensuring practicality and the logical and mathematical queries those plans can't give adequate security assurance against possible difficulties. We have studied some of these research works and analyzed the best possible ways to come to the desired level of privacy preservation for cloud computing. The security analysis shows that the confidentiality of numeric information is strongly protected against cloud providers in our proposed architecture.
