Secure Deduplication with Authorized Duplicate Check Using Convergent Encryption in Cloud
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 3
Abstract
Increased growth of cloud storage turns the focus of cloud service providers to save their resources to earn more profit by renting them to the multiple cloud users. One of the main factors that utilizes more space and causes resource unavailability for new cloud users is the presence of duplicate copies of data files of different owners. Data duplication is one of the most efficient technique which attempts to reduce the multiple redundant copies of single file into the same file. To provide the memory consumption in the considerable manner, in this work convergent key encryption based duplicate reduction is introduced. This mechanism will encrypt the data file by using the part of content of same file which would be stored along with the encrypted copy of data file. A new user, in order to upload a new file needs to send the convergent copy of own file to the cloud service providers which will be matched with the other copy of file. If it already exists, then the redundant storage of files can be avoided considerably. The experimental results of this work prove that the proposed approach leads to a better result than the existing work in terms of accuracy.
