In this paper we are going to say an efficient technique that describe how integrity is maintained in storage of the data. Cloud computing is used to store the data from various resources by the user. It is very complex for the user to store whole data within the system. In that case cloud has to provide to store as much large amount of the data as user wants. This Stored data has to be integrated by cloud in very efficient way and maintain with the help of Trusted Third Party Auditor (TTPA). In this paper, we present two scheme based on homomorphism verifiable response and hash index hierarchy. We propose a secure cloud storage system supporting data integrity and availability in multi-cloud storage. We further extend our result to enable the TPA to monitor for multiple users simultaneously and efficiently. Our resulting is focuses on introduces lower computation & communication overheads in comparison with the non co-operative approaches.
