“… Data Owner Management: In case that a real data owner uploads the data later than the data holder, the CSP can manage to save the data encrypted by the real data owner at the cloud with the owner generated and later on, AP supports re-encryption of at CSP for eligible data holders. Figure.2 is referred from [1] which illustrates the procedure of data deduplication at CSP with the support of private server based on the proposed scheme. We suppose that user saves its sensitive data at CSP with protection using , while user is a data holder who tries to save the same data at CSP.…”

Cloud computing deals with the practice of using a network of remote servers hosted on the Internet to store, manage, and process data, rather than a local server or a personal computer. The most important and popular cloud service is data storage. The data which is of primary importance is stored in an encrypted manner over the cloud so as to maintain its privacy. Hackers can access the data and can cause serious damages to the proprietary data and for its privacy concern data is stored in encrypted form. Now in cloud storage, deduplication technique is used by cloud service provider (CSP) to maintain the space complexity, privacy and to avoid redundancy. This is done by avoiding duplication of data and maintains a single copy of that particular file. However in the management of big data using encrypted manner for deduplication files is tedious task. Traditional deduplication scheme cannot work in encrypted manner because encrypted data are saved as different contents by applying different encryption keys. Whereas the present scenario of deduplication scheme lacks privacy or it is suffered from weakness in providing privacy. In this paper, we propose a scheme to deduplicate encrypted data stored in cloud based on ownership challenge and proxy reencryption. It integrates cloud data deduplication with access control. We evaluate its performance based on extensive analysis and computer simulations. The results show the superior efficiency and effectiveness of the scheme for potential practical deployment, especially for big data deduplication in cloud storage.

“…Moreover, in CAONT-RS, a cryptographic hash generated from the initial data is used instead of the random key of the AONT transform. Furthermore, the authors in [28] have introduced a technique of data ownership challenge and proxy re-encryption (PRE) to manage encrypted data storage with de-duplication.…”

Exponential increase in data inside endeavors is making a gush in the storage requirements and its security. Typical encrypting techniques of separable nature suffer against powerful adversaries due to the exponential improvement of computing power. Therefore, some cloud storage systems apply erasure coding in addition to encryption to prevent adversaries from revealing or/and controlling stored information. Nevertheless, still a powerful adversary can extract useful information from a compromised server. In this paper, a new storage scheme is introduced implying an AllOr-Nothing (AON) encryption mode to separately randomize the encrypted blocks and hashing the resulted pseudorandom blocks altogether afterwards, and with the aid of the salting technique, called Replicated BYTE, integrity is ensured. The scheme will be called Randomized AON plus Replicated BYTE (RAON-RB). By employing systematic Reed Solomon erasure coding, the proposed scheme will be more applicable to distributed systems. The proposed scheme is secure even if all but one storage servers have been compromised and even if the encryption key is disclosed. Moreover, to resist share modification and localize faulty server(s), the proposed scheme verifies the received shares before they are involved in the reconstruction process, and hence, the scheme can save superfluous computations as well.

:-The explosive growth of multimedia contents, especially videos, is pushing forward the paradigm of cloudbased media hosting today. The wide attacking surface of the public cloud and the growing security awareness from the society are both calling for data encryption before outsourcing to cloud. Data de-duplication has been widely used in backups to save storage space and network bandwidth. Under the circumstance of encrypted videos, how to still preserve all the service benefits of cloud media centre remains to be fully explored. Videos may have to be encrypted before outsourcing for privacy concerns. For practical purposes, the cloud media centre should also provide the adaptively disseminate videos to heterogeneous networks and different devices to ensure the quality of service. This paper discusses various ideas related to security and video de-duplication when user stores data in the cloud.
