Introduction
People always search internet to hide data and transfer it across to your friends. Imagine you get a MP3 file with your password in it. Now you can transfer any confidential file or data via audio file (MP3, WMA, WAV, APE). Later on same can be retrieved easily. Researcher of International Institute of Cyber Security comments “we have seen forensics cases where information is shared using these steganography channels“.
Using this we can also convert the MP3 extension to (.ape, .wav, and .flac). This application is very simple to use and easy to understand. Now we will move on to step by step tutorial on how to use DeepSound.
