Cloud is platform where client can store its large amount of data. Cloud computing has gain market of data storage. Service is faces some attack or vulnerability then there is irretrievable losses to the client. The traditional cryptographic techniques based on hash functions and signature schemes cannot support for data integrity verification without local copy of data. Due to vast amount of data stored on cloud it is very difficult to download whole copy of data security audit is an important solution enabling trace back and analysis of any activities including data access.
