This document discusses steganography, which is the process of hiding a secret message within an ordinary message. It begins with a definition and brief history of steganography. It then explains how modern digital steganography works, encrypting data and hiding it within files like images, audio, and video by modifying file contents. The document lists several common file types used for steganography and some available steganography tools. It concludes with step-by-step instructions for using steganography to hide files within a JPEG image on a computer without using additional software.

3. Steganography
from the Greek word steganos meaning “covered” and the
Greek word graphie meaning “writing”
Steganography is the process of hiding of a secret
message within an ordinary message and extracting it at its
destination.
Anyone else viewing the message will fail to know it
contains hidden/encrypted data

4. Steganography (continued)
Modern digital Steganography
data is encrypted
then inserted and hidden, using a special algorithm
which may add and/or modify the contents of the file
This technique may simply append the data to the file,
or disperse it throughout
Carefully crafted programs apply the encrypted data
such that patterns appear normal

9. Implementation: Steganography
Hiding the file in jpeg without any software.
We can hide the confidential content in jpeg file

10. Requirements
Winrar
Command prompt

Step 1: - Put all the files you wish to hide in the folder

folder named hidden.
Step 3:-
Now Look For Any jpeg image and name it
logo.jpeg and put it in the folder hidden.

13. 08/11/13
Step 4:-
Open command prompt make sure your working directory is c:/hidden

14. 08/11/13
Step 5:-
Now type in cmd COPY /b logo.jpeg + secret.rar output.jpeg[logo.jpeg is
the picture you want to show and secret.rar is the file u want to hide and
output.jpeg is the file which contains both.

15. 08/11/13
Step 6:-
After this you will see output.jpeg in c:/hidden.open it and it will
show the picture .now try opening the same file via winrar :)
So In these Way we can stegnograph any king of extension and
hide our sensitive information and make it secrete .
