• Recently, digital contents are copied easily because of the development of digital technology. So digital watermark technique which aims at copyright protection of digital contents becomes more and more important, and various watermarking methods have been proposed. In this paper, we proposed a method of digital watermark for still image by using wavelet packets, and examine the robustness of the watermarking method against several image processings. This method can be easily applied to the watermark for video because in this method, embedded data are detected without original image. Therefore, we extend the wavelet-based watermarking method to the case of watermark for video.
