Data outsourcing to cloud storage has recently become a trend. Economic advantage is the significant reason. A large number of clients or data owners store their important data in remote servers in the cloud and it is provided back to them whenever needed. Data owners don't even leave a copy of the data in their local computers so as to save the storage space. By sending the data to be processed in the cloud, data owners transfer control of their data to a remote party that may raise security challenges. Sometimes the data stored in the cloud is so important that the clients must ensure that it is not lost or corrupted, i.e., the integrity of data has to be ensured.
