| Summary: | 碩士 === 玄奘大學 === 資訊管理學系碩士班 === 99 === In this thesis we use the spline interpolation technique to embed the secret data in the wave form of the original audio data. We set the control points,adjust the control points of the partitions, to rebuild the spline curve to fit the original curve. We use the different between original and spline curve to embed the secret data to be a stego-audio. The extracting steps are simply to use the unchanged control points to compute the spline curve then find the different between spline curve and the stego-audio, to obtain the embedded secret data. The experiments show the control points to adjust the spacing can be embedded in a larger volume.
