Keywords: Provable data possession | Multi- cloud | Cooperative | Parallel | Distributed

In this paper we are going to say an efficient techniquethat describes how integrity is maintained in storage of the data. Weprovide this by using the concept of Provable data possession whichsupports a good service and migration of data in a distributed cloudenvironment, where we take into account of multiple cloud serviceto store and also to maintain the data of the clients. We herebydeliver a new concept called cooperative provable data possession(CPDP) using hash index hierarchy and homomorphic verifiableresponse. Security of the system is proved based on a scheme zeroknowledgeproof system. We use optimal parameters to improve thesystem performance efficiently and cost of computation for theclient and cloud storage providers.
