Secure and Efficient Deduplication Using Hybrid Cloud Approach

Abstract

In cloud computing, the big attention always is on security, about the abilities in which the shared data must be stored in high level security system, not all the users can access in the cloud, just who has the privilege given by the cloud itself or by who owns the data and so on. In addition, and as we all know that the customers are buying clouds to get benefits of never mind about the infrastructure and to be sure that all their data will totally be in safe. There is also big attention on how to never duplicate the files in cloud in order to reduce the amount of storage space because as we know that the customer is paying to get the storage and for sure nobody wants his data to be repeated in his system. For that, this paper will discuss a type of deduplication of files securely by giving just the owner the rights to choose the users who will be able to get access and have the right to upload or download files, and the use of AES algorithm as a way to encrypt/decrypt.
