For the sensitive information, the best privacy demand must be supported in commercial, technical and legal regulations. In this system we used combination of steganography and cryptography techniques in order to improve imperceptibility, robustness, payload capacity and to transmit data securely. As the preprocessing step, Arnold scrambling and discrete wavelet transform (DWT) techniques are used over the secret image. Then the referable values are calculated from the values of transformed secret image with the use of a secret key and embed these referable values in the video file by least significant bit (LSB) technique. Moreover, the secret key is encrypted with a pre-shared key by a new stream cipher Twisted Exchange Algorithm. And the result encrypted message is embedded behind the audio file by Parity coding technique. As the experimental results, performance of the system is tested with different real time images and various video quality files and measured by different parameters (PSNR, MSE), then it is also analyzed with attacks.
