Double coding mechanism for robust audio data hiding in videos

This paper proposes a simple and robust method of audio data embedding into videos. Robustness in this method comes because of the use of double coding mechanism. Here double coding means using two kinds of codes on the same data one after another. This provides more security and reliability to the hidden data into video. As security is the most important matter of concern in present data communication scenario, thus our proposed method provides satisfactory results. The method performed in wavelet domain by using pseudo random codes and morse codes. The performance of this method is evaluated by MSE (Mean Square Error) and PSNR (Peak Signal to Noise Ratio). Further testing is done on videos after embedding, by exposing it to video compression technique. The obtained test result doesn't affect much to the quality of extracted audio data.
