| Abstract | ||
| In this paper, a method of a steganography is introduced for hiding secret data in digital speech signal. Hiding in speech becomes a challenging discipline, since the Human Auditory System is extremely sensitive. The proposed method is used to embed binary sequence with high data rate by modulating the amplitude of WAVE file. The embedding process utilizes the amplitude modulation of the cover signal; the manipulation of the sample depends on its two previous samples and next two samples. By using this hiding method, good hiding rate is achieved. All of the fidelity measures (Mean Absolute Error, Mean Square Error, Signal to Noise ratio and Peak Signal to Noise ratio) obtained in the tests have indicated good results for PSNR. In this method the reconstructed data is exactly the same as secret data. | ||
