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

Abstract- Provable data possession (PDP) is one of the procedure to make sure the integrity of data in storage outsourcing. Here in this paper, we talk to the creation of an efficient PDP method for distributed cloud storage to preserve the scalability of service and data migration. On the origin on homomorphic verifiable response and hash index hierarchy we anticipated a efficient cooperative PDP (ECPDP) method. We verify the security of our method founded on multi-prover zero-knowledge proof method, which can satisfy knowledge accuracy, fullness, and zero-knowledge assets. As well, we expressive performance optimization apparatus for our method, and in particular present an capable method for selecting finest parameter values to reduce the addition expenses of storage service bringers and client. Our experiment shows that our solution pioneers communication overheads and lower addition in evaluation with non-cooperative approachs
