Implementation of Client-Side Deduplication on Encrypted Data with Public Auditing in Cloud Storage

Cloud storage is one of popular cloud service model that stores data on the Internet through the cloud computing provider who manages and provides Storage as a service to the end users. In cloud storage huge amount of data will becomes duplicated due to the multiple uploads from the different users for the same data. The cloud servers want to reduce the volume of data stored by the client which has the similar content and the client wants to maintain the integrity of the data uploaded to the cloud storage. To achieve this there are several models defined using the deduplication and integrity auditing delegation techniques. This paper work is to show an implementation of the combining the deduplication algorithm with the data integrity auditing algorithm to achieve the goals of removing the duplication of data and providing the integrity of data to the client. The data considered will be in encrypted form and the hash data is used to verify the correctness of the data. The proposed algorithm will satisfy the fundamental security requirements and provides an user interface for the client and the server admin to present the proper management of the data stored on cloud storage. The project work is implemented using the java language on Google drive storage.
