Cloud storage is a service model in which data is maintain, manage and backup remotely and made available to users over a network. Data Sharing is beneficial activity in cloud memory. The main challenge is maintaining data privacy with respect to untrusted parties i.e., cloud service provider, as well as providing relevant query results in real-time to authenticated users and it shows how to protectively, effectively scalable data is shared with others in cloud database. Existing approaches either compromise Confidentiality, security and privacy of the data or suffer from high communication cost between the server and the user. To overcome this problem, the proposed system uses dual transformation and encryption over spatial data. User fire encrypted queries on encrypted database present on a cloud server and encrypted results are returned to the user. The result is decrypted at the user end. Along with the database query, database user roles are mentioned which provides restricted database access to the user. The proposed system provides encryption level as well as database level security and requires only one round of communication for query execution.
