Due to the high maintenance and estimating costs, the customer is unable to keep a big volume of data on his local system. This is why the client provides cloud storage. The customer has security concerns such data integrity, confidentiality, etc., when storing data on the cloud. Clients may need to utilize data storage across many cloud servers. Both distributed storage and integrity checking are required, although the former is more pressing due to the need to reduce verification costs. Data stored on several cloud servers may be protected using a method called distributed provable data possession. It allows customers to check the safety of their outsourced data without having to download it all. In light of the foregoing, we present a new methodology for ensuring data integrity across several cloud storage providers using identity-based distributed proofs of possession (RDI-IDPDP). Based on distributed computing and Provable Data Possession, a concrete RDI-IDPDP protocol is built. The proposed RDI-IDPDP protocol is safe when the computational Diffie-Hellman (CDH) problem is hard, the decisional Diffie-Hellman (DDH) problem is easy, and the Gap Diffie-Hellman (GDH) groups are small. Additionally, our RDI-IDPDP methodology is both effective and flexible. Client verification, third-party verification, and Identity-based public-key cryptography that does away with the need for cumbersome certificate administration are all within the purview of the proposed RDI-IDPDP protocol.
