“…Latest work was proposed by Wang H. which was an ID based RDPC approach for multi cloud storage [1]. In 2007, provable data possession (PDP) paradigm was proposed by Ateniese et al [2], where the verifier can check remote data integrity with a high probability. Based on the RSA technique, they provided two provably secure PDP schemes.…”

“…The total communication is about (16)*n+255+c bits where n is number of blocks requested, in this approach we are assuming single query submission. The scheme [2] gives considerable performance but causes additional cost c for client request initiation and major communication overhead due to client reference. If client needs to generate challenges with small durations, the constant value grows rapidly.…”

Cloud-based outsourced storage relieves the client's load of storage management and preservation by providing an equivalently flexible, inexpensive, location-independent platform. As clients no longer have physical control of data, outsourced data integrity checking is of crucial importance in cloud storage. It allows the clients to verify data intactness and correctness without downloading the entire data. As the verification is to be done at client end, the integrity checking protocol must be efficient to save client's time. Another aspect of the protocol is flexibility, which improves the quality of integrity checking by allowing user specific block partition size. Moreover in case of company oriented scenario, maintaining log records of each verification request can help in security analysis. Taking these three points into consideration, we have proposed the flexible, automated and log based RDPC model as: Auto ID-RDPC model for singlecloud storage. The proposed model is based on bilinear pairings and RDPC technique. The approach eliminates certification management with the help of Identity management and additionally provides log management towards data integrity. The model makes client free from initiating verification request and keeps track of previous records which reduces client's time. The principle concept here is to make data integrity checking a painless job for any client. Our results demonstrate the effectiveness of our approach.

“…So, it is clear that the auditing schemes on the ID-based cryptography system will reduce the costs of the data users and the auditor. Many ID-based public auditing schemes are proposed [20][21][22][23]. But, in ID-based public auditing schemes, the PKG (private key generator) knows any user's private key.…”

With cloud computing being integrated with wireless body area networks, the digital ecosystem called cloud-assisted WBAN was proposed. In cloud-assisted medical systems, the integrity of the stored data is important. Recently, based on certificateless public key cryptography, He et al. proposed a certificateless public auditing scheme for cloud-assisted WBANs. But He et al. 's scheme is not a scheme with privacy preserving. After many checks on some of the same data blocks, the auditor can derive these data blocks. In this paper, we propose a certificateless public auditing scheme with privacy preserving for cloud-assisted WBANs. In the proof phase of the proposed scheme, the proof information is protected from being directly exposed to the auditor. So, the curious auditor could not derive the data blocks. We also prove that the proposed scheme is secure in the random oracle model under the assumption that the Diffie-Hellman problem is hard, and we give a comparison of the proposed scheme with He et al. 's scheme in terms of security and computation cost.

“…This lack of control for privacy data would exhibit data confidentiality and privacy protection problem. For the CSP, some errors may occur, such as software or hardware failures and operational errors of system administrator [2][3][4][5]. For maintaining the CSP's reputation, he/she usually tries to hide data loss incidents.…”

More and more organizations outsource their data to remote cloud servers (RCSs). Data owners rent the cloud service providers (CSPs) infrastructure to store their unlimited resources by paying fees metered in month or gigabyte. For increasing the availability and scalability of data, the data owners store their data replicas on multiple servers across multiple data centers. Data owners should ensure that the CSPs actually store all their copies according to the service contract. In this paper, we present an efficient dynamic multicopies possession checking scheme that has the following properties: (1) the data owner uses fully homomorphic encryption (FHE) algorithm to generate multiple copies; (2) the scheme supports data block dynamic operation; (3) the scheme supports third-party auditor's public validation. Finally, security analysis and experimental results show that our scheme can resist forgery, replacement, and replay attack and perform better than some other related scheme published recently.
