Advanced Approach of Data Integrity Verification for Multicloud Storage

Vaibhav Bharati, Manisha Patil

Abstract In the field of storage area, cloud computing is an emerging field which is raising its importance to large extent. Every user wants to store large capacity of data. Users want to acquire storage devices for storing this data. The capacity of the storage devices is the limitation parameter. And so the data is stored online or it is outsourced which makes the security of data vulnerable. In this paper the prime focus is on maintaining the data integrity and hence security. Security can be maintained by using three main parameters that are confidentiality, integrity and availability. Provable Data Possession (PDP) can handle these issues more effectively which is nothing but the proof given by service provider to the data owner according to demand. The project proposes an effective PDP model for verification of data integrity on distributed multicloud storage by using web-servers and Trusted Third Party. 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 (Multiprover- ZKPS) which is an Interactive Proof System are proposed. Keywords: Advanced Cooperative Provable Data Possession, Cloud Service Provider, Multicloud storage, Web Server based Multicloud, Zero Knowledge Property
