The document proposes an identity-based distributed provable data possession model (ID-DPDP) for verifying the integrity of data stored across multiple cloud servers. It aims to efficiently verify data integrity without downloading the entire file. The proposed ID-DPDP protocol is based on bilinear pairings and is provably secure under the computational Diffie-Hellman assumption. It also supports private, delegated, and public verification of data integrity based on the client's authorization.
