An audio Watermarking Algorithm Based on Chaos
This thesis proposes a new algorithm of the Chaos-based audio data hiding.The Chaos theory is introduced in design a new algorithm of the audio data hiding:with one section of audio as the watermarking,the Chaotic sequences select one part of the original audio signal as the carrier,and then embed the Chaos-encrypted audio watermarking into the carriers wavelet coefficients.Experimental results show that embedded watermark is imperceptibility and robust to many attacks,such as noise adding,re-sampling,low pass filtering,reverberation,MP3 compression and re-quantization and so on.
