In cloud computing, data owner can outsource their data on cloud server and only the authorized user can access or request for this data. This service is called as database-as-a-service. But there are different issues related to the confidentiality, correctness, query and access permission of outsourced data because cloud is managed by un-trusted third party. Owners are always suspected about security of the data. So the authors consider this as basic idea for propose concept. The existing system does not provide security against possible attack of clouds, but the propose system can provide security against collusion attack, DDOS attack.
