New adaptive capacity of audio steganography based on the wavelet transform

WithF. Pan, J. Shen & Y. Zhang

MP3stego [1] devised by F. Petitcolas is currently a popular audio steganography tool, but A. Westfeld proposed a steganalysis method[2] based on block length variance is against it. In addition, StegHide, Hide4PGP, Security Suit and other audio steganographys tools use LSB (Least Significant Bit) [3] algorithm in the time domain, but as the bits that are replaced increasing, the imperceptibility is worse and worse.
