Cloud computing helps users to store massive data and allows them to process or retrieve the data whenever required without the aid of any infrastructure investment. But in the cloud, the privacy of the data is a major concern. For processing the data, data is classified into multiple data sets. So in order to maintain the privacy, the common approach used is to encrypt all intermediate data sets and store in the cloud. But this paper will increase the cost and also will consume more time which would be a big challenge.
