INTRODUCTIONWHAT IS DEDUPLICATION?

OBJECTIVE

•Providing Secure client side

deduplication for cloud storage.

EXISTING SYSTEM

• For saving resources consumption in both network bandwidth

and storage capacities, many cloud services, namely Dropbox

apply client side deduplication.

• Existing deduplication can make it easy for outsiders to know

what's already on storage servers.

PROPOSED SYSTEM

• Proposed the use of the convergent encryption, i.e., deriving

keys from the hash of plaintext and a security model for secure

data deduplication.
