IRJET - A Novel Approach Implementing Deduplication using Message Locked Encryption
0 likes20 views
This document proposes a novel approach to implementing data deduplication on the cloud using message locked encryption. It aims to overcome limitations of existing deduplication techniques like convergent encryption by using erasure code technology, encryption algorithms like DES and MD5 hashing, and tokenization to securely store and protect client data on the cloud. The proposed system gives clients proof of ownership of their data by allowing them to choose who can access their files and see any changes made over time. The system architecture involves a client uploading encrypted data to the cloud, and recipients selected by the client being able to access and retrieve encrypted pieces of the data.

ABSTRACT: Cloud is the most prominent and fastest-
growing technology after the start of the 20th century. Since
it becomes, most brilliant and intelligent service, accessible
across all the domains of technology makes it vulnerable to
attacks, and even some other errors like replicating of data,
the efficiency of storage, and the amount of space needed. To
sort the problem of duplication and storage of data, Data
compression known as deduplication used on the cloud. We
have implemented a system that overcomes the limitations
which use Erasure Code technology, tokenization, and
encryption algorithms to protect data loaded onto the cloud
by the client. Our implementation sees not only one side of
the problem but also another side; this is how. People always
want their particulars, personals, and essential date to be
perfectly safe and secured, and nobody should control and
rule over except them themselves. So instead of making a
third-party auditor, we have given the power to the client to
choose who is the person can check and access the there
data. The client can even check what happens with the data,
which uploads onto the cloud, which ensures the proof of
ownership principle. Here, I like all good things all together
and nothing impure. It sounds perfect, but we know that
perfection is a myth. Convergent encryption has some
vulnerabilities. That's why we planned to implement
message locked encryption, as described above.
Keywords: erasure code technology, DES, MD5Sum,
deduplication, tokenization
1. INTRODUCTION
In this article, we see the process of deduplication in the
cloud. Traditional deduplication algorithms such as
convergent encryption which fails to protect the data. We
have implemented a technique called Message Locked
Encryption; in this, we used various encryption algorithms
and tokenization with Erasure code technology to protect
and save the data. MD5 Sum is used to check deduplication
between the files on the application.
Our paper is organized as follows. First, we formally
review the present state of data storing and read
performance. Second, we introduce our approach. Third,
we present our experimental methodology. Finally, we
highlight our conclusions and outline future steps.
2. OBJECTIVE
The objective of this project is to implement secure
deduplication on the cloud with all the necessary terms
mentioned terms and not just making it deduplication in
all aspects but also no compromise with the security.
3. LITERATURE REVIEW
3.1 Secure Enterprise and Read Performance
Enhancement in data deduplication
Description: With the tremendous growth of data in the
world, the use of Cloud technology and providers are
gaining more popularity since these types of services
provide end to end-user benefit it is essential to provide
with the best computational power they need. The paper
talks about the proof of retrievability and proof of
ownership concept to save the data of the user from
tampering or manipulation. They used data in the form of
Chunk to retrieve the data readily over the period. It helps
in useful communication of data.[16].
3.2 A Hybrid Cloud Approach for secure Authorised
Deduplication
Description: paper revolves around securing the cloud
storage and adding a way of maintaining ownership of
data. They used the concept of differential privileges of
users to check duplicate data on the cloud. They even used
a hybrid cloud architecture to check the data and save it on
the cloud. The proposed idea in the paper is useful for
backup storage. They showed a lock level encryption on
the file .even private and public cloud is a significant
helpful way to show how data is secured and stored.[3]](https://image.slidesharecdn.com/irjet-v7i4203-210130142919/85/IRJET-A-Novel-Approach-Implementing-Deduplication-using-Message-Locked-Encryption-1-320.jpg)

3.3ASurveyofSecureDataDeduplication
Description: The paper discusses the way and how to
effect storage in the cloud is shown by less costly means
.the article discusses the backup storage and how
companies are spending a lot of money on the room .it also
surveys the method of deduplication which helps the
companies to save the data and money. [2]
4. EXISTING SYSTEM
Since the modern era of the digital world has begun, .the
concern over the storage and accessing of data is also
increased, which inturns gain a lot of attraction of tech
genius and company working to protect it. In late 2000,
after the introduction of the cloud system, the way of
storing and accessing the data has improved a lot in recent
times. Still, various problems also arise with traditional
cloud-based encryption, such as deduplication attacks on
the cloud system. Convergent encryption was introduced
to protect the data and remove deduplication. As time
passed, the encryption technique is disregarded since it is
posed to file system attacks on the server. It also does not
support the principle of POW(proof of ownership). [3]
5. PROPOSED SYSTEM
Paper discusses our proposed technique that we called
message locked encryption on data. Using Erasure code
technology, which results in efficient storage and
encryption, we are using DES and MD5 for hashing
.tokenization for efficient file retrieval. Since it envelops
the message with layers of encryption and by code
technology, we are data breaking into the pieces before
storage, connecting it by tokens for easier retrieval and
protection from attacks. To check deduplication ewe used
a program called MD5Sum, which acts as a checksum to
check the deduplication. We have also provided proof of
ownership by giving the client the power to choose whom
file to be shared and can check what changes have done to
file over time.
6. SYSTEM ARCHITECTURE
The project of ours has three components.
6.1 The client
6.2 The Cloud
6.3 The Recipient
6.1 THE CLIENT
A Client is a person who is the one who uploads data onto
the cloud. He is the one who has the privilege to choose the
person whom the data is to receive.
6.2 THE CLOUD
The cloud is the basis of implementing all the functionality
in the project. All the deduplication related process occur
inside the cloud. People can access after the specific people
in an enterprise designate them.
6.3 THE RECIPIENT
A Recipient is a person who is selected by user access the
client data.

using MySQL API (SSL supported), and the full character
set/Unicode support. [14].
7.2 ERASURE CODE TECHNOLOGY
Erasure codes are a way of data protection in which the
data brakes into fragments, expanded and encoded with
redundant data, and stored across a set of different
locations in the storage media. This technology is used
instead of RAID in various applications and current use
cases in Cloud Storage [9][7].](https://image.slidesharecdn.com/irjet-v7i4203-210130142919/85/IRJET-A-Novel-Approach-Implementing-Deduplication-using-Message-Locked-Encryption-2-320.jpg)

7.3 MD5SUM(CHECKSUM)
MD5 is program that calculates and checks md5 128bit
hashes. It is to verify the integrity of files, as virtually any
change to a file will cause its MD5 hash to change. Most
commonly, md5sum is used to confirm that a file has not
changed as a result of a faulty file transfer, or non-
malicious meddling. The md5sum program is implemented
in most Unix-like operating systems or compatibility
layers, such as Cygwin. [5][6].
7.4 DATA ENCRYPTION STANDARD
The DES is most profound and one of the most important
algorithms used in encryption nowadays. The
programmers use this algorithm in various ways. It is
beneficial to use since it uses the plain text of size 64 bit
and generates block - ciphertext of the same size [18].
7.5 JDK(JAVA DEVELOPMENT KIT)
JDK is a software used for developing java applications
and applets.
7.6 SMTP
These are the security guideline used to allow the
software to send electronic mail on the internet based on
email addresses.
7.7 TOKENIZATION
Tokenization is a technique to provide the token to a given
data to secure the given data and access it with the help of
the token.[17]
7.8 WEB BROWSER
The implementation of ours is going to be in the form of a
web application. So a browser is necessary, although IE-11
is preferred specifically.
7.9 GLASSFISH
This web application is to runs on the localhost with the
help of glassfish. It is an application server that helps in the
smooth running of JAVA EE applications.[13]

9. CONCLUSIONS
In this paper, the notion of effectively storing and retrieval
of data in the cloud with deduplication proposed we used
Erasure code technology to save the data and tokenization
with some encryption algorithm to create the layer of
security around the data to preserve it.
We gave power to the client to check what changes
occurred on the data after uploading the data onto the
cloud. It can also confirm whether the changes occurred
were right or wrong in the file. On the application, we have
a portal that allows the user to check the changes that
occurred to file. At the back, when the receiver uploads the
same file again, the server verifies it against the original
hash created of file for the changes and deduplication .the
result is shown to the client onto the portal.
