High capacity audio watermarking using the high frequency band of the wavelet domain

Abstract

This paper proposes a novel high capacity robust audio watermarking algorithm by using the high frequency band of the wavelet decomposition at which the human auditory system (HAS) is not very sensitive to alteration. The main idea is to divide the high frequency band into frames and, for embedding, to change the wavelet samples depending on the average of relevant frame's samples. The experimental results show that the method has a very high capacity (about 11,000 bps), without significant perceptual distortion 0] and SNR about 30dB), and provides robustness against common audio signal processing such as add noise, filtering, echo and MPEG compression (MP3).

“…Note that high-capacity robust watermarking schemes exist for embedding that amount of information. For example, the method proposed in [17] allows embedding up to 11,000 bits in a second of audio. -10 seed buyers were generated (M = 10).…”

An imperceptible and robust audio watermarking algorithm

“…Many variations among the different algorithms exit; however, the main variation is in the sub-band chosen for embedding the watermark bits. In [27][28][29], the approximation sub-band is used for embedding the watermark bits, while in most algorithms, only one detail sub-band is used to embed the watermark bits [30][31][32][33][34][35][36]. Claims of good imperceptibility and robustness have been reported using the two embedding approaches.…”

“…Thus, it is very important for researchers to achieve a convenient trade-off between the above mentioned properties according to the application requirements. Various watermarking schemes [Fallahpour and Megías, 2011;Cao and Huang, 2012] have been proposed to achieve a better trade-off between these properties.…”
