[2D Graphic] shuiyin DL : 0: 视频水印技术是利用某些特定的算法把一些标志性的水印信息嵌入到视频当中，它用于视频的版权保护，是信息隐藏技术领域研究的一个重要方向。本课题通过分析视频水印技术的发展背景、应用领域、发展现状及其相关理论知识，提出了一种在视频关键帧中嵌入水印的算法。该算法首先利用Arnold置乱技术对水印图像进行加密预处理，然后根据欧式距离法提取出视频关键帧，最后通过LSB算法在关键帧中实现水印的嵌入和提取。处理过的关键帧合成视频中后仍然可以正常播放，且不会被人的感知系统察觉或注意到。实验表明该算法合理易实现。-Video watermarking technology is the use of certain algorithms to embed some of the iconic video watermark information to them, it' s the video for copyright protection, information hiding technology research in the field is an important direction. This topic through analysis of the development of the background video watermarking technology, applications, development status and related theoretical knowledge embedded in the paper, a video key frame watermark algorithm. The algorithm uses Arnold scrambling technology to encrypt watermark image pre-processing, and then extract the video key frame according to the Euclidean distance method. Finally, LSB algorithm to embed and extract watermark in keyframes. Treated composite video key frame can still be normal after play, and will not be noticed or noticed the human perceptual system. Experiments show that the algorithm is reasonably easy to achieve.
