SoundKeylogger

An experimental project to demonstrate how a user keyboard input may be sniffed through the pattern analysis of the sounds emitted by the keystrokes (based on pyAudioAnalysis).

This field of study is called Acoustic cryptanalysis, (also known as Acoustic Keyboard Eavesdropping) and is a type of side channel attack towards electronic devices.

This project was created as an assignment for the IF754 - Musical Computing class of 2016.1 at CIn/UFPE.
