Removing Duplication Data in Cloud with Secure Accessibility

Abstract

In recent days, cloud computing offering various resources over Internet. Among those resources, one of the important services is data storage. In order to preserve the privacy of users, the data is stored in cloud in an encrypted form. Deduplication becomes crucial and a challenging task when the data is stored in encrypted form, which also leads to complexity in storing large data and processing in cloud. A usual deduplication method does not work on encrypted data. Cloud does not provide access control and revocation in terms of storage. Hence, the deduplication schemes are not in practice. In this paper, we propose a technique to avoid redundant storage. It incorporates cloud data deduplications with access control. In result we have shown the efficient and practical storage of vast data and its storage. For secured files downloading we will retrieve files by fast keyword searching and files will downloaded having security keys.
