ABSTRACT

This paper facilitates the techniques to be used with the images that cannot be misused by
unauthorized users. This method is to provide the security for images by using key concepts. The
Invisible Watermarking concept is used for secret message and images to send one node to another
node with a private key. A package is developed to attain the above said technology. This package is
mainly applicable for a software company which focuses on how to secure the data from the hackers
while transferring the information. It gives controlled redundancy, data independence, more accuracy
and integrity, privacy and security and also a good performance.

Keywords- Invisible Watermarking, Stegnography, Encryption

1. INTRODUCTION
DIGITAL watermarking is a process of embedding marks which are typically invisible and that can
be extracted only by owner’s authentication. This technology is to be used with the image that cannot

be misused by the unauthorized users. This allows one to do without any distortion and keeping much
better stegno-image quality, also in a reliable and secured manner guaranteeing efficient retrievals of
secret file. Digital watermarking finds wide application in security, authentication, copyright
protection and all walks of internet applications. There has been effective growth in developing
techniques to discourage the unauthorized duplication of data and applications. The watermarking
technique is one, which is feasible to design to protect the data and also applications related The term’
cover’ is used to describe the original message in which it will hide our secret message, data file or
image file. Invisible watermarking and visible watermarking are the two important types of the above
said technology. The main objective of this package is to reduce the unauthorized duplication of data
and application, provide security, authentication, and copyright protections to all walks of internet
applications. During the implementation stage, the system is physically created, necessary programs
are coded, debugged and documented and operating procedures are developed. The test plan is also
established. Based on the specification above, the necessary code is developed in “.NET” and tested
successfully with the test data. Software is tested with real data and the report generated are accurate
and error free. The system is portable and flexible for further development. It gives user friendly
screens to enter data and enquire database. It is also tested on various browsers in order to check the
consistency and reliability. This application has a great impact on the people who want to gather latest
information and very useful as well as user friendly.

2. PROBLEM IDENTIFICATION

Here the problem is to transfer a message in a safe and secure way. Previously we had used the
method of cryptography to transfer a message in a safe way with the help of encryptions and
decryptions algorithm. Growth of internet transferring a message or file using this concept made a
problem since the hackers easily hack the data. To overcome this problem a new technique called
watermarking is used. In this technique the information is using with a media file (image, audio, and
video).Visible Watermarking means information hidden with image but that has visible on the image.
It also made problem to transfer data. So the invisible watermarking scheme is selected for
transferring the information. In this method, the information is hidden with media file, while
transferring data it fully converted as media file. When the receiver wants to retrieve it, he will open
with the help of the private key of receiver. As we are transferring message embedded with image,
audio, video file, while transferring data from sender to receiver it is necessary to encrypt it by private
key. After decryption, the information fully converted as the media file. The receiver decrypts the
message whenever he wants to access by the same key. Likewise, we are transferring the message
with media file.

3. PROPOSED SYSTEM

The most widely used existing method is encryption, which takes data and mixes it up with an
algorithm and a key to output unreadable data. The receiver then must also have a key to decrypt the
data in order to read it. Another form of data hiding is encryptions using steganography.
Steganography is the act of hiding data inside other data. For example, hiding the words into an
image. But we can conceal limited words into image here. The digital images can be protected from
illegal copying and manipulation through the digital watermarking technique. Commonly,
watermarking is built to endure un-malicious or malicious attacks like scaling, cropping, compression
and so forth. It is chiefly intended towards copyright Protection. The proposed watermarking scheme
is blind, since it doesn’t require the original image or any of its characteristics for the extraction of
watermark. This scheme makes use of a binary image as watermark data for protecting the copyrights
of images. The term cover is used to describe the original message in which it will hide our secret
message, data file and image. Once it embeds our secret file into the cover, the new image is known
as the stegno image.
3.1 Software Requirement Specification
The software requirements specification (SRS) is produced at the culmination of analysis task
establishing a complete functional descriptor. Design constraints and the other data pertinent to

2

requirements and refines the function and performance allocated to software as part of the system
engineering. This is the base of all software engineering activities that flow.

3.2 Formal Description
This technology mainly contains four modules, namely authentication, embedding, retrieval module
and data transmission. In that embedding technique covers message embedding, word document
embedding and image embedding. Retrieval module consists of message retrieval, word document
retrieval and also image retrieval. Application architecture is as shown in fig. 2. The main objectives
concentrated in data design are, controlled redundancy, data independence, accuracy and integrity,
privacy and security also performance.

4. FUNCTIONAL DESIGN
Functional design is otherwise known as hierarchy (or) structural chart. It is a graphical tool for
representing hierarchy. The following principles are used for architectural design.

4.1 Modularity and Partitioning

Each system should consist of a hierarchy of modules. Lower level modules are generally small in
scope and size compared to higher level modules and serve to partition processes into separate
functions.

4.2 Coupling
Modules should have little dependence on other modules in a system. Coupling between the modules
is the strength of interconnection between modules (or) a measure of interdependence among
modules. There are two types of coupling. First one is highly coupled (modules are joined by strong
inter connections), and the second one is loosely coupled (modules have weak inter connections).

4.3 Interface Design

The user interface design activity focuses on supporting the interaction between the user and the
developed site. User Interface design is frequently a prototyping process where the working models or
prototypes of user interface methods are design and modified several times with the feedback from the
customer. Data design activity focus on the design of the structure of the database and files to be used
by the proposed websites. In this paper the data design of the website have a detailed description of
data flow.

5. PROCESS DESIGN

This activity focuses on the design of the user interaction forms i.e. the program and procedures
needed to develop the forms. (See fig. 1 , 2)

5.1 System Specification
It formalizes the design of the applications user interface methods, Database structures and
processing, and controlled procedures. Therefore system designers will frequently develop hardware,
software, data and personal specifications for proposed system.
5.2. Low Level Design

The procedural design or component level design is also treated as low level design which will deal
with the lowest level of the functional details such as implementation details etc., Addition and
modification of user information procedure is given below.

5.3 Adding User information

6. IMPLEMENTATION

Operating procedures must be developed. The test plan must be established. The implementation stage
normally ends Execution is the stage of the system when the theoretical design is turned into a
working system. During the implementation stage, the system is physically created, necessary
programs are coded, debugged and documented and with formal system test involving all components
and procedures if the implementation stage is not carefully planned and controlled. It can cause chaos.
Thus it can be considered to be the most crucial stage in achieving a new successful system. Based on
the specification above, the necessary code is developed in “.NET” and tested successfully with the
test data (See Fig. 3).

7. FORSEEABLE ENHANCEMENTS

Every application has its own merits and demerits. This invisible watermarking technology has
covered almost all the requirements. Further requirements and improvements can easily be done since
the coding is mainly structured or modular in nature. Changing the existing modules or adding new
modules can append improvements. Further enhancements can be made to the application, so that the
windows functions very attractive and useful manner than the present one.
8. CONCLUSION

We hope that the developed software would be of great help in the process of transferring data in a
secured way. This is used to automate secure file management system and to overcome client
difficulties by providing all the latest information to achieve the desire goals of them. This software
includes all the facilities like navigation from one page to another page using links. Software is tested
with real data and the report generated are accurate and error free. The system is portable and flexible
for further development. It gives user friendly screens to enter data and enquire database. It is also
tested on various browsers in order to check the consistency and reliability. This application has a
great impact on the people who want to gather latest information and very useful as well as user
friendly.
