Hiding Data Behind Image

The method i am going to describe is called as Stenography.

It means Hiding anonymous data behind a single image. This is how they Cheat.

Step1: Create a folder in your C drive and name it as “hack”

Step 2:Copy all the images you want to hide and also the image behind which you want hide into this directory.
 

Step 3: Now select the images you want to hide and add them to archive i.e keep them in winrar. You can do this by right clicking the selected images->add to archive->click ok.


Now you will see one more file named “hack.rar” in your directory.

Step 4: now open command prompt and change your root to your current directory as shown in the figure and type the following command.
Copy /b 1.jpg + hack.rar romance.jpg
 Here “1.jpg “ is the image behind which you want to hide.
“hack.rar” is the file of images to be hidden.
“romance.jpg “ is the output file that we want.
After executing the following command, we will see an extra image called “romance.jpg” as shown in the figure.

Now you can delete all the files except “romance.jpg”.
If you double click the file, it opens a normal image. 
But you can see the hidden files by opening the file with winrar.

In this way you can hide any kind of data you want behind any thing.
It is best to hide sensitive data always like this.
Thank You.
