Abstract

Digital video watermarking is one of the solutions for copyright protection of digital multimedia data and draws great attention of both researchers and digital video owners. In this work, a new hybrid digital video watermarking method which uses the discrete cosine transform (DCT) and discrete wavelet transform (DWT) is proposed. Each frame is processed with one of the DCT and DWT methods or a combination of them, half of a frame by the DCT method and the other half by the DWT method. Selection of the watermarking for each frame in the video is determined randomly. The proposed method has undergone several attacks in order to check its robustness and compare to the DCT and DWT methods. The proposed hybrid method including a watermarking diversity throughout the video improves robustness against attacks.Keywords: Digital video watermarking, discrete cosine transform (DCT), discrete wavelet transform (DWT), copyright protection.
