基于Android系统视频水印算法的研究

Research on video watermarking algorithm based on Android system

随着信息科技和移动互联网的飞速发展,智能手机或平板录制的视频版权安全问题日益突出,因此要进行手机或平板视频与数字水印相结合的研究。文中提出了基于Android系统的视频水印系统,并提出基于空间域的双伪随机序列的水印算法,不仅提高了鲁棒性,同时满足了透明性和实时性的要求。

With the rapid development of information technology and mobile Internet,the recorded video copyright security of smartphone or tablet is particularly prominent. So the research on smart phone or tablet video which combined with digital watermarking is generated. This paper proposes the video watermarking system based on the Android system as well as the pair of pseudo random sequence watermarking algorithm based on space domain,which improves the robustness and satisfies the requirement of transparency and real-time.
