An effective video watermarking for video copy right protection helps to avoid piracy of videos. The video is read and it is splitted into the frames and they are arranged in the binary tree structure according to the number of frames in the video. The root frames are selected with the help of secret key generated by dedicated cryptographic algorithm to extract feature points. The feature points of frame and frame-patch of different users is taken and it is extracted by using Harris feature point extraction. With the help of these feature points, the embedding and extracting regions are identified. Then the watermark content is embedded in Discrete Wavelet Transform (DWT) domain. In the extraction process, we synchronize the embedded region from the deformed video by using feature point matching method. The watermark synchronization process is performed to get the robust watermarking locations before watermark embedding and extraction is performed. Then rotation, scaling, translations are performed and the values are measured.
