In the present scenario, businesses and people are outsourcing database to minimize their effort and to obtain a low cost service. In order to provide the sufficient functionality for SQL queries, many secure database schemes have been proposed. However, such schemes are vulnerable to privacy leakage to cloud server. For numerical range inquiry (>, <, and so forth.) these neglect to give adequate security insurance. A portion of the difficulties faced are privacy leakage of statistical attributes, access patterns and so on. Likewise increased number of queries will release more information to the cloud server. We have studied some of these research works and analyzed the best possible ways to come to the desired level of privacy preservation in the case of cloud computing. We have proposed a two-cloud architecture for secure database, with a series of intersection protocols that provide privacy preservation to various numeric-related range queries. Security analysis shows that privacy of numerical information is strongly protected against cloud providers in our proposed scheme.
