ABSTRACT
With cloud storage, users can expand their storage capacity without upgrading their hardware, removing a major resource bottleneck that can otherwise prevent them from taking full advantage of the benefits of cloud computing. Cloud data is always transmitted in an encrypted format to safeguard sensitive information and user privacy. However, encrypted data may require a great deal of extra space, and gaining quick access to shared data in the cloud may prove challenging for authorised users. We are still having issues with replica as a storage and management mechanism for encrypted data. Historically, deduplication techniques have been built around a single application architecture, giving data owners or cloud servers full authority over the process. However, they are limited in their ability to meet the changing needs of data owners by the volume of sensitive information they store. We introduce a strategy for managing data storage that is heterogeneous, spanning many Cloud Service Providers, in a way that is both flexible and synchronous in terms of access control and deduplication (CSPs).
