Advanced Cooperative Provable Data Possession based Data Integrity Verification for Multi-Cloud Storage

Abstract

Cloud computing is an emerging field which is raising its importance in the field of storage of data.Every individual, firm or organization wants to store data that has the limited storage capacity.For that purpose, there is need to outsource data to some Cloud Service Provider, there arises a problem of security of data.Security comes with 3 main parameters confidentiality, integrity and availability.For these issues, there is term called Provable Data Possession, it is nothing but the proof given by service provider to the data owner when there is demand by owner.Paper proposes an effective PDP model for integrity verification of data on distributed multicloud storage by using web-servers and Trusted Third Party.Here proposed the use of techniques such as, Advanced Cooperative Provable Data Possession (Advanced CPDP), Homomorphic Verifiable Response and Hash Index Hierarchy for Multiprover Zero Knowledge Proof System which is an Interactive Proof System.
