HIDE ANY TEXT INSIDE IMAGES AND AUDIO FILES

Are you familiar with the word "Steganography"? If not, this post is dedicated to you.  

Wiki says:

"Steganography is the art and science of writing hidden messages in such a way that no one, apart from the sender and intended recipient, suspects the existence of the message, a form of security through obscurity."

"Its a trick for hiding some text in images keeping the original image unaffected"  

These are all the tricks used for this kind for hiding text within any image. With the last one being the best.

1st trick: (worst*)
First download imagehide software. Its a freeware utility for hiding text in an image. Click here to download Imagehide. The interface of Imagehide is very simple .Once it is installed all you have to do is to load the image in which you want to hide your text (Steganography) type the text and hit the Write data option.You can also password protect the text so that it can only be opened with the help of a password.


WTF! who's gonna download a 500kB software for such a small task??

2nd trick: (knowledge-able/didn't work*)

Step 1 Copy an image file to c: of your computer.

Step 2 Copy the text(which you want to hide) to clipboard, by writing it in notepad and selecting it, right clicking it, then copy.

Step 3 Open cmd, by going to Start — All Programs — Accessories — Command Prompt.

Step 4 In cmd type :

cd \

echo “your text to hide” >> “image.jpg”.

Step 5 Now right click on image.jpg — Open with — Notepad. You can see your hidden text at the end of your image file contents.

Though all the comments attached to this post were negative with problems "access denied". This can be bypassed by Right clicking at CMD and choosing Run as admin:

I also tried doing this (in Win7) and what I got in return was Half-success (may be I have tried it wrong way or committed some mistake in the procedure). The image remained as it is and a new file got created with same name and " at the beginning also filetype was JPG'.

Here is the screen-shot with high-lighted result:

3rd trick: (working) 

Step1: Open your notepad and write whatever text you wanna hide and save the text file as text.txt (or any other name).

Step2: Now choose the image in which you would like to hide your text.

Keep both the files in the same directory (i recommend C:).

Now open your Command prompt. If you have kept your bith file in C:, you must run the Command prompt as Admin. (see the 1st screen-shot on how to do this)

Step3: Navigate to the folder where your files are stored using “cd” command.

or just keep the directory C: if you have kept both file in C: drive. 

Now,type the following command:

copy /b Image.jpg + Text.txt Output.jpg

                                                                                     and press enter.
Where, Image.jpg is the name of your image file and Text.txt is the name of your text file. Give a space between [Image.jpg + Text.txt] and [Output.jpg].
Note:Make sure that Image file name comes first and then the text file name after copy /b. Doing the opposite will not work.
You’ll see an Output.jpg file that will get created in that same directory. You could now open the image, the image will open normally. Now the trick comes, open the Output.jpg file with notepad, scroll down to the end of the text and you’ll see something like this:

4th trick: (Best)

It really takes long time doing all this tricks step by step. But in view, the best trick for Steganography is simply right click on the image in which you want to enter your secret text and open it with notepad. Then, scroll down to the end of the text and simply enter your secret text there and the save the image.

Thats all! Try re-opening the image and you will still see the entered text in there. Isn't this the best trick? 

Note: Remember to enter your secret text only in the end of the text. Entering it anywhere in between will ruin your image.
