摘要：with the rapid development of network and digital technology, security of digital contents is a serious problem. Digital watermarking can provide an effective security protection to digital contents. A digital watermark is embedded in an electronics document to provide multimedia copyright protection and authentication purposes. In this paper we start from some basic knowledge about digital watermarking. Then we go deeply with algorithm. We discuss digital video watermarking scheme based on Principal Component Analysis. Lastly we discuss applications of watermarking. A video file is a continuous collection of static images, and each image is composed of three color channels. Algorithms used over here allow us to embed a watermark in the three color channels RGB of an input video file. The main advantage of this method is that the same or multi-watermark can be embedded into the three color channels(R,G,B) of the image that helps to increase the robustness of the watermark. Furthermore, using PCA transform allows choosing the suitable significant components into which to embed the watermark
