StegIbiza: New Method for Information Hiding in Club Music
This addresses the problem of covert communication for users in club music settings, but it is incremental as it adapts existing concepts like Morse code to a new carrier.
The authors tackled the problem of information hiding in club music by modulating tempo with a 3-value coding scheme, achieving a result where testers could not identify differences with a 1% margin of changed tempo in the worst case.
In this paper a new method for information hiding in club music is introduced. The method called StegIbiza is based on using the music tempo as a carrier. The tempo is modulated by hidden messages with a 3-value coding scheme, which is an adoption of Morse code for StegIbiza. The evaluation of the system was performed for several music samples (with and without StegIbiza enabled) on a selected group of testers who had a music background. Finally, for the worst case scenario, none of them could identify any differences in the audio with a 1% margin of changed tempo.
