Hide Data Behind Images Without Using Softwares

In my previous article i have given a small intro to steganography. There you can find the basics of steganography, it's uses and the techniques used.
In this article we will see how to hide data behind images without using softwares.

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.
