Hide text behind images (Stegnography)


Stegnography is the technique to place text content behind images. This is generally performed by the terrorists to hide the Secret messages behind the images and conveying the message via sending the image via internet

Windows internal commands as well as Stegnography tool 'ImageHide' can be used to perform this technique.

Steps To Perform Stegnography

1. Let's say image file is 'Pic.jpg' and text file is 'Messages.txt'. The command to hide the message would be :

Copy /b Pic.jpg+Message.txt Final.jpg

2. To view the Hidden messages, Right click on Final.jpg > Open With > Notepad > Go to End of the File

Note: Your Dos prompt root directory should point to path where image and message is stored otherwise you will have to use full path like "C:\Pic.jpg". and I'll prefer you to use double quotes surround path like:
Copy /b "Pic.jpg"+"Message.txt" "Final.jpg"

Hope You Will like it.
