Hide Data/files Behind an JPG Image file[tutorial]

Ritesh Warke

Art of hiding information in image files is called as Steganography. Today I am going to explain you how to hide your data files such as text,mp3,exe,3gp,avi etc. behind an image file.This tutorial will help you to store as many files you want behind an .jpg file.

The tools needed are,

1) PC

2)7-ZIP,Winrar ,or Winzip installed on your PC.

Here the tutorial starts,

• Create a folder Hideit on your system drive C:/ drive and copy the files you wanted to hide behind an image file along with that image file into that Hideit folder.
• Select the files you want to hide(not image file that we are using to hide files behind),after right clicking you will get an option to add them to a compressed ZIP or RAR file.
• Now name the compressed folder what ever you want say Ritesh.rar
• Now you have go to Start then click on Run, In Run type cmd and press enter now command prompt window will open.
• Type cd/ (this is a command to get to the root directtory i.e. C:/) and hit enter,now type cd Hideit ( meaning of this command is to change the directory to Hideit)
• Now type in this  copy /b image.JPG + Ritesh.rar image.jpg  and hit Enter.(I have used word image.jpg by considering that the name of the JPG image that we are using to hide our data is image,you can change name to whatever you want,also make sure you should change .rar to .zip if your compressed file is in .zip format).
• Now all your data is hidden behind the image,jpg file,you will clearly see that the size of your image file is increased according to the compressed archive.
• You can see or extract the hidden files any time by opening image.jpg file using winrar or winzip(or any equivalent software).
