Perlindungan Hak Cipta Konten Video Digital dengan Robust Video Watermarking Menggunakan Algoritma Undecimated Dual-Tree Complex Wavelet Transform

Abstract

In digital era, there are often problems of theft and copyright claims on digital video content. Therefore, a Steganography method with Robust Video Watermarking Techniques is needed to label ownership or copyright of a digital video using the Undecimated Dual-Tree Complex Wavelet Transform Algorithm in the embedding and extraction process. Video watermarking uses *.mp4 format and *.jpeg/jpg image format, the system is designed using 2 programming languages, namely HTML/CSS as a medium for displaying output results, and Python for performing mathematical embedding and extraction calculations, testing is done with 5 files with the format *.MP4 with different duration. The results of the research in chapter 4 are on testing that with the same process as the file size and long duration, the embedding and extraction process will take quite a long time and the file will get bigger. Tests were carried out such as MSE, PSNR with the smallest MSE value of 0.81 and the largest PSNR value of 49.00 db where there is no significant difference to the original frame by naked eye, and other tests Croping, Rotating, changing the resolution of the watermarked video, doing watermarking from the watermarked frame so that when the above test is carried out and the video extraction is carried out on the tested video the result is that the watermark image cannot be read, and is not resistant to attack, but in testing the watermarking of the watermarked frame in test no. 3 – 6 the results are resistant to attack.
