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.

1. IDENTITY-BASED DISTRIBUTED PROVABLE DATA POSSESSION IN MULTI-
CLOUD STORAGE
ABSTRACT:
Remote data integrity checking is of crucial importance in cloud storage. It can make the clients
verify whether their outsourced data is kept intact without downloading the whole data. In some
application scenarios, the clients have to store their data on multi-cloud servers. At the same
time, the integrity checking protocol must be efficient in order to save the verifier’s cost. From
the two points, we propose a novel remote data integrity checking model: ID-DPDP (identity-
based distributed provable data possession) in multi-cloud storage. The formal system model and
security model are given. Based on the bilinear pairings, a concrete ID-DPDP protocol is
designed. The proposed ID-DPDP protocol is provably secure under the hardness assumption of
the standard CDH (computational Diffie- Hellman) problem. In addition to the structural
advantage of elimination of certificate management, our ID-DPDP protocol is also efficient and
flexible. Based on the client’s authorization, the proposed ID-DPDP protocol can realize private
verification, delegated verification and public verification.
EXISTING SYSTEM:
The foundations of cloud computing lie in the outsourcing of computing tasks to the third party.
It entails the security risks in terms of confidentiality, integrity and availability of data and
service. The issue to convince the cloud clients that their data are kept intact is especially vital
since the clients do not store these data locally. Remote data integrity checking is a primitive to
address this issue. For the general case, when the client stores his data on multi-cloud servers, the
distributed storage and integrity checking are indispensable. On the other hand, the integrity
checking protocol must be efficient in order to make it suitable for capacity-limited end devices.
Thus, based on distributed computation, we will study distributed remote data integrity checking
model and present the corresponding concrete protocol in multi-cloud storage.

2. DISADVANTAGES OF EXISTING SYSTEM:
 Data checking in more complex using multi servers.
 Needed large storage space.
 In sufficient data loss.
PROPOSED SYSTEM:
In identity-based public key cryptography, this paper focuses on distributed provable data
possession in multi-cloud storage. The protocol can be made efficient by eliminating the
certificate management. We propose the new remote data integrity checking model: ID-DPDP.
The system model and security model are formally proposed. Then, based on the bilinear
pairings, the concrete ID-DPDP protocol is designed. In the random oracle model, our ID-DPDP
protocol is provably secure. On the other hand, our protocol is more flexible besides the high
efficiency. Based on the client’s authorization, the proposed ID-DPDP protocol can realize
private verification, delegated verification and public verification.
ADVANTAGES OF PROPOSED SYSTEM:
 It has more significant storage space.
 It provides secure public data’s.
 Using Private Key generation.
