Analysis of hybrid cloud approach for private cloud in the de-duplication mechanism

Data De-duplication is one of the important techniques for eliminating duplicate copies of repeated data, and has been widely used in cloud storage to reduce the amount of storage space. To protect the confidentiality of data differential authorized duplicate check is used. Different from the traditional duplication system, different privileges of user are considered besides the data itself. We present this authorized duplicate check in hybrid cloud architecture. The hybrid cloud architecture proposes about both the public cloud and the private cloud. the private cloud plays an important role in this system, moreover the security of this system is less, as the private cloud of this mechanism is not secure, unauthorized access of the data resulting in fail in security. In order to provide more security, the private cloud is provided with multilevel authentication. As a proof of concept we have analyzed the existing Hybrid de-duplication system that is the public cloud and private cloud. We have showed that our system is more secure and provide confidentiality to data. In this paper, detail of our proposed system has been explained along with the architecture, data flow and algorithms.
