Elimination Of Repeated Data Copies With Enhanced Security In Hcloud
Journal Title: International Journal of Research in Computer and Communication Technology - Year 2015, Vol 4, Issue 9
Abstract
Intending at economically solving the trouble of deduplication with discrepancy privileges in cloud computing we regard as a hybrid cloud structural design consisting of a public cloud and a private cloud. Dissimilar existing data deduplication systems, the private cloud is occupied as a proxy to tolerate data owner/users to firmly achieve duplicate check with differential privileges. Such architecture is realistic and has concerned much attention from researchers. The data owners only outsource their data storage by employing public cloud while the data operation is handled in private cloud. A new deduplication system supporting differential duplicate check is planned under this hybrid cloud architecture where the S-CSP dwells in the public cloud. The user is only authorized to carry out the duplicate ensure for files marked with the corresponding privileges. The users without equivalent privileges cannot perform the duplicate check. Additionally such unconstitutional users cannot decrypt the cipher text even conspire with the S-CSP.
