Policy and Attribute Based Deduplication System

Abstract

Cloud storage is a platform where we can store and access the data through internet. Many Social and business applications are backing up their data in cloud. So, the requirement of cloud storage increases day by day. But most of the files present in the cloud storage are redundant. Removing redundant files in cloud is one way to manage the storage space requirement. For that purpose, we apply File-level data deduplication technique. In this paper, a method for deduplication is proposed which is named as policy and attribute based dedupe system. This system includes access control over files to enhance the security. It also reduces the storage space and increase the security of user data.
