Hide it!!(basics of steganography)

Steganography is a technique of hiding data in a audio or a image file. Originally designed for spies, this technique is often used by malicious elements and government officials. But now a days all sorts of people use it to hide their data even if its sensitive or not.
There are a bunch of tools that are available on the internet that you can download and use. All these tools have simple wizards which can be used to hide your data. 
For example I can use any random software to explain it but I would prefer using DeepSound to explain it.

How to? 

1. Download and install Deepsound on your computer.
2. Now open Deepsound, you will see a window like this.
3. First of all select the carrier file in which you want hide the data.                            
4. Now add the files which you want to hide.
5. Hit encode to start the encoding.
6. Now you will you can check the check-box under encrypt to set a password if you want to make it even more secure else just hit OK.                         
7.  To extract the data just open the file under the  carrier file tab and hit extract secret file.
