Secure Cloud Backup for Data Sources Based on Blockchain

Abstract

Users can upload, save and download their data with cloud storage. The cloud does however handle the user’s generation of data, as well as devices created by the fast Internet development of stuff, including such webcam, and IoT and edges cameras. This growth in outsourced data volume has posed two main problems in cloud infrastructure cloud management: optimum data storage and data protection. Cloud storage employs a deductibility strategy to prevent redundant data to solve the former problem and uses cryptography to solve the latter problem. Both of these questions however are orthogonal. The convergent encryption is concurrently tackles the two problems. The conventional systems rely on web server, however which put some confidence in a private entity that may malfunction in one stage. In this paper we propose a new, transparent, authenticated online storage framework, which removes data replication from the security of the file and enhances the credibility of blockchain software. Two different approaches to data deduplication secrecy are discussed, in particular: double hazing is used and symmetrical encryption is used. We have implemented the suggested architecture in order to show stability and accessibility in spite of the increase request throughput requirements for cloud data processing.\
