The art and science of writing hidden messages in the image is known as steganography. Its the safe and cool way to pass your message to your loved ones with out knowledge of anyone else.
Can’t believe?? save the above image on your desktop and open it with WinRAR OR WinZip. See the magic. 🙂
Hiding data inside the image was never easy task but below tricks will show how to do this quickly and easily.
Below trick uses JPEG(JPG) image to store any data inside it. when i say any data means literally any file, .txt, .doc, .ppt, .exe, .pdf,.mp3 and so on..
Step 1 :
Take a JPEG and a text file for this trick. you can use any file instead of .txt, I have taken it for the sake of easy understanding. save it on C:\> drive
Now compress these two files to .zip or .rar file. save all these files on C:\ drive
Now go to command prompt.
start–> run–> type ‘cmd’ and press Enter.
start–> type ‘cmd’ and press Enter. (for windows 7)
a command prompt will open. go to C:\> by pressing cd..
Now combine image and .RAR OR .ZIP file to create new image, this new image will look same as original image. in command prompt, Type
c:\>copy /b monalisa.JPEG+secretMessage.rar NewMonalisa.jpeg
It will create new image same as original image but now its with the .rar file embedded inside it.Note that size of new image has increased.
[For enthusiasts /b converts the files in to binary format ie 010101.. thats why its possible to add .rar file in the image.]
But how to Extract the data from that image?
Its also very simple Just open that image file with winRAR or change its extension from .jpeg to .RAR and
open that compressed file to your PC.
Thats it !! Good Luck !
