Abstract

A method to implement digital audio watermarking in the frequency domain is presented. The embedding is performed by using chaos based sequences to increase the signature hiding properties. The proposed scheme takes into account the MPEG psychoacoustic model I to improve the robustness against the MP3 compression. Some tests have been performed to verify the system robustness against the MP3 compression and also against the signal cropping, re-sampling, re-quantization and filtering.
