Confidential and efficient query services in the cloud with RASP

Now a day cloud computing is quite popular. By using cloud users can save their cost for query services. But some of the data owners are hesitate to put their data's in cloud because, sometimes the data may be hack like as inside attackers when they use in cloud unless the confidentiality of data and secure query processing will be provided by the cloud provider. In cloud if the user can get secured query service then the efficiency of query processing will be increased as speed of retrieve and the workload of the query processing will also be saved. To provide the confidentiality and efficient query service used RASP method. RASP denotes RAndom Space Perturbation. It also combines order preserving encryption, random projection and random noise injection. To process the range query to kNN query here used kNN-R algorithm and also analyze the RASP method will secure the multidimensional range and it will increase the working process of query.
