Provable records possession (PDP) is a method for making sure the integrity of statistics in storage outsourcing. In this paper, we tackle the building of an environment friendly PDP scheme for dispensed cloud storage to aid the scalability of provider and statistics migration, in which we reflect onconsideration on the existence of more than one cloud carrier carriers to cooperatively shop and hold the clients data. We current a cooperative PDP (CPDP) scheme primarily based on homomorphic verifiable response and hash index hierarchy. We show the protection of our scheme based totally on multi-prover zero-knowledge proof system, which can fulfill completeness, information soundness, and zero-knowledge properties. In addition, we articulate overall performance optimization mechanisms for our scheme, and in specific existing an environment friendly approach for choosing top-quality parameter values to reduce the computation charges of consumers and storage provider providers. Our experiments exhibit that our answer introduces decrease computation and verbal exchange overheads in contrast with non-cooperative approaches.
