Robust and High Capacity Steganography in Audio
Yu Liu · Jisuanji gongcheng · 2008
This paper proposes an audio information hiding algorithm.It uses CDMA spread spectrum scheme to preprocess secret message,and uses a discrete wavelet transformation to obtain the Approximate Coefficient of the Cover-audio(ACOCA).The preprocessed secret message is embed in the discrete cosine transform domain of the ACOCA.Experimental results show that the proposed algorithm has high capacity and is very robust to wide range of attacks.These attacks include amplitude-normalize,quick filter,special distortion,noise reduction,and these combined attacks.
