Audio Steganography Using High Frequency Noise Introduction

This paper presents a new method of audio steganography that allows character data to be encoded into audio in a way that is indiscernible to prying third-parties. Unlike typical methods of audio steganography that propose storage by modifying the least significant bits or the phase of the audio data, this approach makes use of frequency ranges that are undetectable to the human ear. The method proposed in this paper provides for a reasonably high-bandwidth and is resistant to common detection and prevention techniques.
