Stopping the Duplication of Data Storage in Public & Private Cloud Storage using S-CSP

Abstract

In recent days, cloud computing became an emerging service model which provides highly available storage and massively parallel computing. Cloud storage enables users to out- source their data backup over remote cloud providers. Managing ever increasing growth of data, is became a great headache. To address this problem, data deduplication technique is introduced which eliminates redundant data copies by keeping a physical copy. For security concerns encryption becomes a necessary before updating data into the cloud. Since these are two challenges that we focused in this paper. For achieving deduplication along with data security, secure hashing algorithm is used.
