A Secure Verifiable Storage Deduplication Scheme on Bigdata in Cloud

Abstract

Cloud Computing is a emerging technology where we can get platform as a service, Software as a service, infrastructure as a service, while getting storage as a service from cloud. Memory management are very most important in cloud computing. In existing paper user can upload text files only and not a secured. In existing paper we propose a user can upload all type of files (jpg, gif, png, audio, video, pdf, ppt) using deduplication technology. We propose a scheme to deduplicate encrypted data stored in cloud based on ownership challenge and proxy re-encryption. It is commonly used to reduce the space and bandwidth requirements of service by eliminating redundant data and storing only a single copy of file using cloud service provider. Here we propose secure deduplication to avoid the same files uploaded multiple times.
