| Abstract |
Digital watermark technologies conceal the information of video contents that presents who is the owner and/or who is the user. In spite of various attempts to insert watermark, trials to mark information of users or buyers into contents have not been successful. It is the reason that the rates of detection is decreased seriously if there are some attacks to the contents such as resizing or bitrate decreasing. In this paper, the algorithm to insert the coded watermarks of users into video contents and to detect them without original contents under attacks will be described. |
