| Summary: | This paper propose a method for security threw hiding the image inside the speech signal by replacing the high frequency
components of the speech signal with the data of the image where the high frequency speech components are separated and analyzed using
the Wavelet Packet Transform (WPT) where the new signal will be remixed to create a new speech signal with an embedded image. The algorithm is implemented on MATLAB 15 and is designed to achieve best image hiding where the reconstruction rate was more than 94% while trying to maintain the same size of the speech signal to overcome the need for a powerful channel to handle the task. Best results were achieved with higher speech resolution (higher number of bits per sample) and longer periods (higher number of samples in the media file). |
