Abstract

Lack of security of transmission channels in the network at the time of data transmission and testing the comparison of encryption processes using the DCT and DWT Steganography Methods on MP4 Video Files. The goal of the study was to test the quality of stego-video after the image insertion process through measurements of Peak Signal to Noise Ratio (PSNR) and Mean Square Error (MSE) parameters.The study analyzed the insertion of image files into video files using discrete cosine transform (DCT) and discrete wavelet transform (DWT) algorithms. The image files used are jpg and gif format and the video file format uses AVI and MP4. After testing both DCT and DWT algorithms as many as 5 videos and also 5 images, each stego-video experienced changes in MSE and PSNR values. 2. The designed system successfully knows the comparison of MSE and PSNR values from both algorithms by showing different numbers. To improve results and add more image and video files to better know mse and PSNR values. 2. For the system that is built next to be further refined by displaying the results of MSE and PSNR values each doing DCT and DWT processes.
