Data Security and Deduplication Framework for Securing and Deduplicating Users’ Data in Public and Private Cloud Environment

Abstract

Maintaining the security of data stored in the public or private cloud is a more tedious task. The cloud is the only arrangement for storing enormous amounts of data, but there is a possibility of storing the same data more than once. The traditional security system generates different unreadable data for the same readable content of a file. Therefore, it is necessary to address data security of the cloud and duplication in cloud storage. This paper concentrates on developing a data security and deduplication framework with different security techniques and mechanisms to address the said difficulties in the cloud. The framework proposed in this paper focuses on reducing security vulnerability as well as data duplication. The paper describes the components used in the frameworks. The main research contribution of the framework is having enhanced the convergent encryption technique, key generation techniques, and deduplication mechanism for maintaining a single copy of data in the cloud. The proposed framework’s efficiency is measured by implementing the work by developing a cloud-based application that coded for all the procedures of the proposed framework and tested in the cloud environment.
