In the field of storage area, cloud computing is an emerging field which is raising its importance to large extent. Every user wants to store large capacity of data. Users want to acquire storage devices for storing this data. The capacity of the storage devices is the limitation parameter. And so the data is stored online or it is outsourced which makes the security of data vulnerable. In this paper, the prime focus is on maintaining the data integrity and hence security. Security can be maintained by using three main parameters that are confidentiality, integrity and availability.
