Achieving Secure Deduplication by Using Private Cloud and Public Cloud

At the present time, cloud computing furnish large volume of area for storage of data as well as huge equivalent computing at affordable rate. Due to advantages of cloud computing it turn out to be widespread; extreme quantity of data can be stored on cloud. But, rise in size of data has raised numerous new obstacles. Deduplication is one of significant compression method of data for reducing carbon copy of replicating data that being used in cloud to reduce the volume of storage area and it utilizes less network bandwidth. Data Deduplication is the convergent encryption technique that has been projected to encrypt the data before it’s been sent out that preserve the confidentiality of responsive data. For better data security, it makes the initial effort that officially point out the dilemma of authorized data Deduplication. There are numerous new Deduplication structures that provides authorized duplicate check in hybrid cloud structural design that acquire negligible overhead over standard operation.
