Audio Steganography for Covert Image Data Transmission through Frequency Spectrogram

Abstract

In the current internet community, secure data transfer is limited due to its attack made on data communication. So more robust methods are chosen so that they ensure secured data transfer. One of the solutions which came to the rescue is the audio Steganography. But existing audio steganographic systems have poor interface, very low level implementation, difficult to understand and valid only for certain audio formats with restricted message size. Here have chosen sound steganography, where we aim to create a code that could encode a picture into sound and then read it on a frequency spectrogram. We reach our goal and we created a main code that has also an encoding part divided in amplitude computation and wave’s computation, and a frequency spectrum code.
