Hiding and extract any Text File behind an Image File/Audio File using Windows Command Prompt

 

The steps for hiding and extract any Text File behind an Image File/Audio File using Windows Command Prompt

We can see that, Most of our data not 100% secure on interconnected devices which are connected in network. So, we need to take care of our device or file security. Therefore, we need to create some basic level security. For that we are going to hide our text file behind any Image File or Audio File by using Windows Command Prompt.

1) First we need to take any Image File along with our Confidential File.


2) Type any confidential message into our TXT File (Confidential File). Just like below:

3) Then open command prompt, and type following command on it.
  • copy /b ImageFileName.png+TextFileName.txt Result.png

In binary mode, copy /b copies all characters (including special characters such as CTRL+C, CTRL+S, CTRL+Z, and ENTER) to the device, as data.

4) Then open Result.png as normal photo viewer first. We see that only image is display, and now open it as notepad. In notepad, we see that unreadable format text at starting and then go to the end we can see that our original message present there.


We successfully hide our text behind Image File. We can use Audio File as well using similar process.
