Survey of Integrity Verification in Multi-Cloud Storage by Efficient Cooperative Provable Data Possession

Abstract

Provable data possession (PDP) is one of the techniques to ensure the integrity of data in storage outsourcing.Here in this paper, we speak to the creation of an efficient PDP method for distributed cloud storage to maintain the scalability of service and data migration.On the basis on homomorphic verifiable response and hash index hierarchy we projected a cooperative PDP (CPDP) method.We confirm the security of our method based on multi-prover zeroknowledge proof scheme, which can satisfy knowledge soundness, fullness , and zero-knowledge properties.As well, we expressive performance optimization mechanisms for our method, and in particular present an capable method for selecting finest parameter values to reduce the addition expenses of storage service providers and client.Our experiment shows that our solution introduces lower addition and communication overheads in evaluation with noncooperative approaches.
