Hiding a file in an image file is called 'Steganography'. It's a technique using which we can exchange data across the world over internet without using any encryption or decryption method. What happens actually is we just bind the file (we want to send) with an image file. The actual file becomes hidden within an image file and hence becomes more protected. The image file functions normally as it should. Even if someone snoop into our network and gets his hands on over that image, he just can't unbind the actual file hidden within that image until unless he doesn't know the exact trick. Lets see how to do this. Follow the steps below carefully.

Hiding the File

  1. Create a new folder anywhere in your system. For example: "D:\NewFolder".
  2. Select all files you want to hide and get them zipped using WinZip or WinRar. Let this file be called 'womb.rar'.
  3. Select an image file like 'ppp.jpg' in which you want to hide your 'womb.rar'.
  4. Place both 'ppp.jpg' and 'womb.rar' into the folder you created.
  5. Open command prompt (press 'Window+R', type 'cmd' & press 'Enter' key).
  6. In Command Prompt window, navigate to the folder where you placed both 'ppp.jpg' & 'womb.rar' files. Just type "cd folder-path" for example: cd D:\New Folder in Command Prompt.
  7. Type following command very carefully in Command Prompt:copy /b ppp.jpg+womb.rar ppp.jpg.
  8. Well done! If everything went good, 'womb.rar' (contains all those files you want to hide) has been hidden in the 'ppp.jpg' (image file you selected).

Accessing the Files

  1. Realize that 'ppp.jpg' is a JPEG extension file. Hence its properties will remain same. It'll work like any other JPEG image file. But your data 'womb.rar' is still hidden within it.
  2. Know that there are two file extraction methods:
    • Method 1: Simply right-click 'ppp.jpg' and select 'open with winrar'. You (or anyone you send the file to) can see 'womb.rar' zipped file there. Just unzip it and here your all files are.
    • Method 2: Change the extension from 'ppp.jpg' to 'ppp.rar'. Then, double-click to open it. You can see 'womb.rar' zipped file there. Just unzip it, and here are all your files.

Warnings

  • You may need administrative privileges for Command Prompt in order to navigate to the folder you created for your files. Log in to your system using the administrator account.
