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.
FORMULATED SOLUTIONDEDUPLICATION ON ENCRYPTEDD DATA
CONVERGENT ENCRYPTION
