Detailed Investigations on a A Hybrid Cloud Approach for Secure Authorized Deduplication
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 2
Abstract
Data deduplication is one of important data compression techniques which is for eliminating duplicate copies of repeating data, and has been widely used in cloud storage in order to reduce the amount of storage space and save bandwidth. To protect the confidentiality of sensitive data while supporting deduplication, the convergent encryption technique has been proposed to encrypt the data before outsourcing. To better protect data security, paper’s makes the first attempt to formally address the problem of authorized data deduplication. Different from traditional deduplication systems, the differential privileges of users are further considered in duplicate check besides the data itself. Also present several new deduplication constructions supporting authorized duplicate check in hybrid cloud architecture. Security analysis demonstrates that the proposed scheme is secure in terms of the definitions specified in the proposed security model.
