Identity-Based Distributed Provable Data Possession in Multi-Cloud Storage 
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 verifierโ€™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 DiffieHellman) problem. In addition to the structural 
advantage of elimination of certificate management, our ID-DPDP protocol is also efficient and 
flexible. Based on the clientโ€™s authorization, the proposed ID-DPDP protocol can realize private 
verification, delegated verification and public verification. 
In cloud computing, remote data integrity checking is an important security problem. The 
clientsโ€™ massive data is outside his control. The malicious cloud server may corrupt the clientsโ€™ 
data in order to gain more benefits. The formal system model and security model are existing 
models. 
In the PDP model, the verifier can check remote data integrity with a high probability. 
Based on the RSA, they designed two provably secure PDP schemes. PDP allows a verifier to 
verify the remote data integrity without retrieving or downloading the whole data. It is a 
probabilistic proof of possession by sampling random set of blocks from the server, which 
drastically reduces I/O costs. The verifier only maintains small metadata to perform the integrity 
checking. PDP is an interesting remote data integrity checking model. 
In POR, the verifier can check the remote data integrity and retrieve the remote data at 
any time. On some cases, the client may delegate the remote data integrity checking task to the 
third party. It results in the third party auditing in cloud computing

Identity-Based Distributed Provable Data Possession in Multi-Cloud Storage 
DISADVANTAGES OF EXISTING SYSTEM: 
๏‚ท Does not provide efficiency in remote data integrity checking. 
๏‚ท More expensive. 
๏‚ท The existing system provides less flexibility. 
Remote data integrity checking is of crucial importance in cloud storage. In multi-cloud 
environment, distributed provable data possession is an important element to secure the remote 
data. we propose a novel remote data integrity checking model: ID-DPDP (identity-based

provably secure under the hardness assumption of the standard CDH (computational Diffi 
Hellman) problem. The proposed ID-DPDP protocol can realize private verification, delegated 
verification and public verification. 
ADVANTAGES OF PROPOSED SYSTEM: 
๏‚ท The distributed cloud storage is indispensable. 
๏‚ท Elimination of the certificate management.

The verifier only maintains small metadata to perform the integrity checking. PDP is an interesting remote data integrity checking model. In POR, the verifier can check the remote data integrity and retrieve the remote data at any time. On some cases, the client may delegate the remote data integrity checking task to the third party. It results in the third party auditing in cloud computing Contact: 9703109334, 9533694296 EXISTING SYSTEM: Email id: academicliveprojects@gmail.com, www.logicsystems.org.in
  • 2. Identity-Based Distributed Provable Data Possession in Multi-Cloud Storage DISADVANTAGES OF EXISTING SYSTEM: ๏‚ท Does not provide efficiency in remote data integrity checking. ๏‚ท More expensive. ๏‚ท The existing system provides less flexibility. Remote data integrity checking is of crucial importance in cloud storage. In multi-cloud environment, distributed provable data possession is an important element to secure the remote data. we propose a novel remote data integrity checking model: ID-DPDP (identity-based distributed provable data possession) in multi-cloud storage. The proposed ID-DPDP protocol is provably secure under the hardness assumption of the standard CDH (computational Diffi Hellman) problem. The proposed ID-DPDP protocol can realize private verification, delegated verification and public verification. ADVANTAGES OF PROPOSED SYSTEM: ๏‚ท The distributed cloud storage is indispensable. ๏‚ท Elimination of the certificate management.
