An Audio Hiding Algorithm Based on Spline Interpolation and Wavelet Transform

Abstract:

Based on the characteristics of sampling points to get approximate numerical interpolation point, first to the whole speech signal wavelet decomposition, the extract is not sensitive to the human ear hearing wavelet coefficients as the location of the embedded watermark information, the interpolation factor by using spline interpolation to replace known the low-frequency wavelet coefficients to embed watermark. The simulation results show that the algorithm not only has imperceptibility, such as MP3 compression, low-pass filtering, white noise, sampling, quantitative attack has good robustness. It achieves a better balance in robustness and imperceptibility.
