IMPROVING THE PERFORMANCE OF CLOUD STORAGE THROUGH ELIMINATION OF DUPLICATE ENCRYPTED BIG DATA

Big data means a situation where the logistics of storing, processing, or analyzing data have surpassed traditional operational abilities of organizations. Cloud computing is purported to be the future of the IT industry. In cloud computing environment, as the infrastructure not owned by users, it is desirable that its security and integrity must be protected and verified time to time. Cloud computing marks a true paradigm shift in how the computing would happen in the future and cloud computing is likely to have the same impact on IT industry that foundries have had on the manufacturing industry. Although, providing security to cloud storage and access the information is the significant issue. In this paper, a security system is designed to eliminate the duplicate encrypted big data stored in cloud storage utilizing proxy re-encryption algorithm. The experimental results indicate the effectiveness of the proposed security system for big data deduplication in cloud storage.
