Cloud computing provides massive storage capacity to the users to deploy their applications without any infrastructure investment. Along with those applications a large set of intermediate datasets will be generated, and it is a challenging problem to preserve the privacy of those intermediate datasets. Encrypting all datasets in cloud is generally used in existing approaches. But the authors proposed that, encrypting all intermediate datasets are either cost effective nor efficient because it is a time consuming process for data intensive applications to encrypt and decrypt data repeatedly while performing any operation on that data.
