A Hybrid Cloud Approach for Secure

Authorized Deduplication

Abstract

Data deduplication is one of important data compression techniques for

eliminating duplicate copies of repeating data, and has been widely used in cloud

storage 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, this paper 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. We also present several new deduplication

constructions supporting authorized duplicate check in a hybrid cloud architecture.

Security analysis demonstrates that our scheme is secure in terms of the definitions

specified in the proposed security model. As a proof of concept, we implement a

prototype of our proposed authorized duplicate check scheme and conduct testbed

experiments using our prototype. We show that our proposed authorized duplicate

check scheme incurs minimal overhead compared to normal operations.

EXISTING SYSTEM

Data deduplication is one of important data compression techniques for

eliminating duplicate copies of repeating data, and has been widely used in cloud

storage to reduce the amount of storage space and save bandwidth.

DRAWBACK OF EXISTING SYSTEM

One critical challenge of cloud storage services is the management of the

ever- increasing volume of data.

PROPOSED SYSTEM

The convergent encryption technique has been proposed to encrypt the data

before outsourcing. To better protect data security, this paper makes the first

attempt to formally address the problem of authorized data deduplication.

Convergent encryption has been proposed to enforce data confidentiality while

making deduplication feasible.

ADVANTAGE OF PROPOSED SYSTEM

To improve storage utilization and can also be applied to network data

transfers.

Reduce the number of bytes that must be sent.

Eliminating duplicate copies of repeating data.

Reduce the amount of storage space and save bandwidth.

SYSTEM SPECIFICATION

Hardware Requirements

System : Pentium IV 2.4 GHz

Hard Disk : 40 GB

Floppy Drive : 1.44 Mb

Monitor : 15 VGA Colour
