Paper Title
Deduplication System With Security And Improved Reliability

Abstract
Deduplication of data is a technique used for eliminating duplicate copies of records also has been usually used in cloud storage to decrease storage space and upload bandwidth. Though, there is only one copy for each and every file stored in cloud even if such a file is owned by a vast number of users. As a result, deduplication system improves storage operation even as reducing reliability. Still, the challenge of privacy for sensitive data also arises when they are outsourced by users to cloud. Target to address the above security challenges, our system makes the first attempt to formalize the view of distributed reliable deduplication system. We suggest new distributed deduplication system secure in terms of maximum reliability, data confidentiality, Integrity and proof of ownership. The security requirements of data confidentiality and integrity are also achieve by introducing a deterministic secret sharing scheme in distributed cloud storage systems. As a proof of idea, we are improving the future systems and reveal that the incurred overhead is very limited in practical environments.
