In the cloud, When data is de-duplicated, it becomes a single piece of information. By
using the Cloud Data De-Duplication approach, users will be required to upload only one copy of
each file, resulting in significant storage and performance gains. As it is, the existing system has
several flaws. For starters, there is a lack of user-level protection and the level of security given by
the Cloud is lower because the entire data file resides in a single Cloud. This paper proposes a new
system to address these issues. Using the new technology, data is uploaded to multi-cloud storage in
a nonduplicate encrypted format. There are no two data partitions stored on the same cloud. Cloud
data security is now better protected as a result of these changes. The new system generates a One
Time Password (OTP) for every user login in order to further enhance cloud data security. A pregenerated
hash code is used to schedule the de-duplication process. DriveHQ's experimental
analysis runs on Java/Jsp and MySQL.
