Abstract: There has been immense research performed in the area ofcloud and cloud computing. The cloud platform has been known the world over forits ease of use and simplicity. The cloud can be utilized for the purpose ofstorage of any kind and also is capable of proving a very powerfulcomputational power at a relatively low price. Therefore, there has beenincreased interest in this platform which has been attributed to its growth inrecent years. The cloud technology helps reduce the dependency of the user on aspecific fixed set of hardware and storage and move it over to the cloud, whichcan provide ubiquitous storage capability without the need of maintaining andscaling up the hardware. This has to lead to a lot of individuals andorganization including the healthcare facilities, to migrate to the cloudplatform. This introduces a new concern of security, therefore, all the datauploaded on the cloud is encrypted, and this encrypted data is impossible tosearch and reduces the Quality of Experience. Therefore, this paper utilizesthe reverse circle encryption technique to achieve efficient search over theencrypted data.
