摘要: This paper presents a new approach for hiding information in digital audio based on the audio-to-image wavelet transform (A2IWT) and vector quantization (VQ). In our scheme, cover signal is first transformed into an image by utilizing re-sampling coefficients, then secret data are embedded obtained using VQ-based steganographic finally together with remaining coefficients inversely back to stego signal. Experimental results show that proposed scheme effective efficient.
