To Secure Query Services in the Cloud with RASP Data Perturbation

To host day services in public cloud is an best solution to save operating expense. However users have concerns on data security to lost control of infrastructure. RASP used to provide security to the setting of cloud based computing while enabling much faster query processing compared to the encryption based approach. In RASP encryption data confidentiality and query privacy are guaranteed when appealing it for range query and kNN. In order to process the range query to kNN query here we used kNN-R algorithm.
