摘要：The Cloud computing needs are increasing due to more of user access to the cloud databases. The cloud service providers should provide efficient services since more number of users are trying to access cloud databases for their storage requirements. But, in this scenario the issue that is to be addressed is Security. Hence User privacy must be protected in addition to querying of cloud. Therefore different private searching techniques are developed by researchers to provide privacy. This paper presents description of different private searching techniques like Ostrovsky, COPS, EIRQ (with trusted ADL) and EIRQ (No trusted ADL) protocols which are currently available for retrieving information from clouds. The Pallier cryptosystem is used by the secure search protocols as an encryption scheme.
