1. Steganography at Large
1.1 Introduction
Steganography derives from the Greek word steganos,
meaning covered or secret, and graph (writing or drawing).
On the simplest level, steganography is hidden writing,
whether it consists of invisible ink on paper or copyright
information hidden in an audio or image file.
Where cryptography scrambles a message into a code to
obscure its meaning, steganography hides the message
entirely. These two secret communication technologies can
be used separately or together—for example, by first
encrypting a message, then hiding it in another file for
transmission. As the world becomes more anxious about the
use of any secret communication, and as regulations are
created by governments to limit uses of encryption,
steganography’s role is gaining prominence.
What Steganography essentially does is exploit human
perception, human senses are not trained to look for files
that have information hidden inside of them, although there
are programs available that can do what is called
Steganalysis (Detecting use of Steganography.)
Steganography hides the secreted message within the host data set
and presence imperceptible and is to be reliably communicated to a

8
receiver. The host data set is purposely corrupted, but in a covert
way, designed to be invisible to an information analysis.

1.2 Where Hidden Data hides?
It is possible to alter graphic or sound files
slightly without losing their overall viability for the
viewer and listener. With audio, you can use bits of
the file that contain sound not audible to the human
ear. With graphic images, you can remove redundant
bits of color from the image and still produce a
picture that looks intact to the human eye and is
difficult to discern from its original.
It is in those bits that stego hides its data. A
stego program uses an algorithm, to embed data in
an image or sound file, and a password scheme to
allow you to retrieve information.
1.3 What does the project do?
- Hiding the text message in audio or image file.
- Encryption of the same message, so as to
support more secure steganography.
- The decoding of the message, decryption and
source message retrieval are also supported.

3. Objective
The goal of steganography is to covert communication. So, a
fundamental requirement of this steganography system is that
the hider message carried by stego-media should not be sensible
to human beings.
The other goal of steganography is to avoid drawing
suspicion to the existence of a hidden message. This approach of
information hiding technique has recently became important in a
number of application area
This project has following objectives:
• To product security tool based on steganography
techniques.
• To explore techniques of hiding data using encryption
module of this project
• To extract techniques of getting secret data using
decryption module.
Steganography sometimes is used when encryption is not
permitted. Or, more commonly, steganography is used to
supplement encryption. An encrypted file may still hide
information using steganography, so even if the encrypted file
is deciphered, the hidden message is not seen.

4. Module Description
Home:
This page will have the home display of the software and it will
have the link to other modules also. Once the module is open it can
then link to the database and retrieve the settings from the database.
This module is also responsible to apply the settings on the other
modules. This module will have only database reading capabilities and
not writing.
Hide / Encrypt the data :
 Create a File using the Text editor : This module will be used
to create a file that will contain the Plaint text with no
formatting. Also the file created under this module will not be
saved in the system and can and will only be saved as a
Encrypted (Visual encryption) or will be concealed under an
image file.
 Import file: In this module we will be able to import a file from
the computer and that will be concealed under an image file.
Unhide / Decrypt the data:
 Import file: This module will have the ability to import file(s). It
will be able to decrypt, Unhide the file from the image file and it
will also be able to retrieve the message from the image files
generated by the encryption module using the Visual
Cryptography.

6. Software Support

Operating system:
Windows or GNU/Linux
JDK (1.7) :
The Java Development Kit (JDK) is an implementation of
either one of the Java SE, Java EE or Java ME platforms released by
Oracle Corporation in the form of a binary product aimed at Java
developers on Solaris, Linux, Mac OS X or Windows.
Java is fast, secure, and reliable. I am using Java because of some
the most desirable features of Java. Some of those are list below-
 Security
 Portability
 Java Architecture
 Object-Oriented Robust
 JDBC (Java Database Connectivity)
Swing :
Swing, which is an extension library to the AWT, includes new
& improved components that enhance the look and functionality of
GUIs. Swing can be used to build Standalone swing GUI Applications as
well as Servlets and Applets. It employs model/view design
architecture. Swing is more portable and more flexible than AWT.
Swing is built on top of AWT and is entirely written in Java, using
AWT’s lightweight component support. The architecture of Swing
components makes it easy to customize both their appearance and
behavior.

7. LSB ALGORITHM for IMAGE
7.1 Implementation:
Structure of image files is that an image is created from pixels
that any pixel created from three colors ( red, green and blue
said RGB) each color of a pixel is one byte information that
shows the density of that color. Merging these three color makes
every color that we see in these pictures. We know that every
byte in computer science is created from 8 bit that first bit is
Most-Significant-Bit (MSB) and last bit Least-Significant-Bit
(LSB), the idea of using Steganography science is in this place;
we use LSB bit for writing our security information inside
pictures. So if we just use last layer (8st layar) of information, we
should change the last bit of pixels, in other hands we have 3 bits
in each pixel so we have 3*hight*width bits memory to write
our information. But before writing our data we must write
name of data(file), size of name of data & size of data. We can do
this by assigning some first bits of memory (8st layer).

7. LSB ALGORITHM for AUDIO
IS WORKS MOSTLY SIMILAR TO THE IMAGE STEGANOGRAPHY

8. (a) User Manual for
IMAGE STEGANOGRAPHY
The Embed stegonographic message box will
get opened where the message is to be
embedded

Then click on the OPEN tab.
Type the message to be embedded

Select the original image and than click to EMBED tab.
Than click to SAVE INTO NEW FILE tab .
Staganographed image get formed.
To decode steganographic image.
Select the open tab.

Select the steganographed image and click the DECODE
tab.
The decode message will displayed in
DECODED MESSAGE box.

8. (B) User Manual
AUDIO STEGANOGRAPHY
The Embed stegonographic message box will
get opened where the message is to be
embedded

Then click on the OPEN tab and give the file name which you
want to encode.

After giving the file type the message you want to encode
and then click the encode button

Visit:
After giving the path of the file click on decode and
give the unique key for decryption

Hence you can see your MESSAGE.
9. Summary
Steganography is a really interesting subject and outside of the
mainstream cryptography and system administration that most
of us deal with day after day.

Steganography can be used for hidden communication. We have
explored the limits of steganography theory and practice. We
printed out the enhancement of the image steganography system
using LSB approach to provide a means of secure
communication. A stego-key has been applied to the system
during embedment of the message into the cover image.
This steganography application software provided for the
purpose to how to use any type of image formats to hiding any
type of files inside their. The master work of this application is in
supporting any type of pictures without need to convert to
bitmap, and lower limitation on file size to hide, because of
using maximum memory space in pictures to hide the file.
Steganography, like cryptography, will play an increasing role in
the future of secure communication in the “digital world”.
