Abstract
In research, steganography of data into video files using Discrete Cosine Transform (DCT) and Discrete Wavelet Transform (DWT) algorithms. Their results show that the value of Peak Signal to Noise Ratio (PSNR) obtained by 29 is lower than the PSNR result of the existing method, therefore further research is needed to increase the value of PSNR. In this research, PSNR value was improved on researchers by doing combination of DCT − 2D algorithm with DWT. The results of the experiments on 12 image samples that the DCT-DWT Combination algorithm is better than the two above algorithms i.e. the average MSE value of 2.35 and PSNR of 44.45.
