Cloud computing is a rising term that offers number of essential focal points. One of the key preferences of Cloud computing is pay according to utilise, and clients will pay by their use of the storage space. Concept of Third Party Service Provider and Auditing are widely used for providing different techniques like data storage, encryption. Data replication is face by clients whenever he is provided with backup management for storing data hence to overcome this problem of redundancy mapping hash key is used as a key factor which is further discussed in paper. How to provide security in the form of integrity, correctness and confidentiality is focused in this paper.
