Survey: Using Multiple Storage Clouds for Data Security on Cloud

Sandeep Nehe | M. B. Vaidya

Abstract: Currently there are several cloud systems which provide storage as a service which are PaaS systems. They provide access to their services via web services. Can we create a unification framework that integrates different IaaS cloud layers in order to collaborate storage space of two or more storage clouds We have one question always in mind i. e. How can we provide security to the files being uploaded on cloud storage People are always worried about the security for the data being uploaded to storage cloud. One way of doing this is encrypting the files being uploaded. This ensured that the files cannot be opened by any other person. But if once decryption key is known then the data can be easily In this paper we proposes a middleware system that authenticates users and uses storage cloud systems such as DropBox, Box. net and OneDrive as backend storage. We provide a layer of security above these storage systems by distributing the storage to each cloud. We also encrypt each segment being distributed. Our middleware split a file being uploaded into segments, encrypt them and then upload each segment to each backend cloud storage. The system maintains all these segmentation, encryption and distribution information and user information to the systems database. When user want to download a file, system again recreate the original uploaded file and allow downloading it. We use web services or web APIs provided storage clouds for implementing this system.
