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.

• 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.

• our proposed authorized duplicate check scheme incurs minimal overhead compared to

normal operations.our proposed authorized duplicate check scheme incurs minimal overhead

compared to normal operations.

ARCHITECTURE

• Cloud computing provides seemingly unlimited “virtualized” resources to users as

services across the whole Internet, while hiding platform and implementation details.

• Today’s cloud service providers offer both highly available storage and massively

parallel computing resources at relatively low costs.

• Cloud computing becomes prevalent, an increasing amount of data is being stored in

the cloud and shared by users with specified privileges, which define the access rights

of the stored data.

EXISTING SYSTEM

EXISTING SYSTEM DISADVANTAGES

• One critical challenge of cloud storage services is the management of the ever-

increasing volume of data.

• Increasing of duplicate data in cloud storage and it increases size of occupation and

increases bandwidth.

PROPOSED SYSTEM

• 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.

• Our proposed authorized duplicate check scheme incurs minimal overhead

compared to normal operations.

PROPOSED SYSTEM ADVANTAGES

• Decreasing of duplicate data in cloud storage and save the server space.

• It Decreases size of occupation and Decreases bandwidth.

• One critical challenge of cloud storage services is the management of the ever-

increasing volume of data.

ALGORITHMS

• Key Gen Algorithm.

• AES Algorithm.

• Tag Gen Algorithm.
