Multiple video watermarking algorithm based on wavelet transform

Digital watermarking techniques embed information in multimedia, such as image, audio and video. The watermark has been resolved copyright ownership and verifying the integrity of content. This paper proposed a watermarking technique based on wavelet transform and binary watermark. The embedded algorithm has been done in two bands of video. Furthermore, the watermark extraction process does not need the original video sequence. The experimental results show the algorithm is more robust and it can achieve copyright protection and authentication.
