In this paper, the authors are proposing an efficient privacy preserving cost effective mechanism through classification and cryptographic approach, when sharing of resources like data in cloud, it should provide security while storing data and privacy over data. In this paper, they are using ID3algorithm for classification of intermediate data set and store into cloud. Before storing the data into cloud the data owner should encrypt the data by using cryptographic algorithm i.e. triple DES technique. If any user required to retrieve data from the cloud, it can be decrypted with same key and it can reduces time complexity and it is cost effective.
