Cloud computing model has become immensely popular with its breakthrough advantages over other computational models. The massive computational power offered by cloud provides the ability of data storage on cloud servers. These being an advantage for cloud user, also raises concerns for data security. Users have to deeply rely on the existing offsite storage architecture for the security of data. The foremost constraints of data auditing are legitimate access of data, availability of data and integrity of stored data.
