A Fusion Cloud Method for Protected Authorised Deduplication
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 5
Abstract
Data de-duplication is one of important data compression techniques for eliminating duplicate copies of same data, and has been used in area of cloud storage to reduce the amount of storage space and saving the more bandwidth. To protect the confidentiality of sensitive data while supporting de-duplication of files, the convergent encryption technique has been proposed to encrypt the data before outsourcing. To protect the security of the data itself, the paper makes the first attempt to address the problem of authorized data de-duplication. Different from other de-duplication systems, the users are further considered in duplicate check besides the data. We also present several new de-duplication constructions supporting authorized duplicate check in fusion cloud architecture. Security analysis explains that our scheme is secure in terms of the definitions specified in the proposed security models. As a proof of concept, we implement a prototype of our proposed authorized duplicate check scheme and conduct test bed experiments using our prototype concept. We show that our proposed authorized de-duplicate check scheme incurs minimal overhead compared to normal operations.
