Summary:We combine recent theoretical and algorithmic advances in the area
of information-hiding with the current mature knowledge-base in the
human audio perception system to propose a novel audio data-hiding
technique that significantly pushes the state-of-the-art in the field.
Our work is based on a combination of advances in two disjoint fields:
information-hiding and human auditory masking. The field of
information-hiding has recently seen a resurgence due to advances in the
understanding of fundamental bounds from information theory. By
integrating this with the human perceptual system knowledge that has
been successfully exploited for several years in the audio compression
community, we derive a new and improved audio data-hiding technique that
finds application in a number of exciting scenarios like music
enhancement and digital communications over analog data channels. Our
preliminary results show that we can embed data at a rate an order of
magnitude higher than existing audio data hiding systems, while being
robust to channel noise
