  Abstract

With the development of video capturing tools, it is possible to attack the watermarks embedded in the video data by the capturing. Since the capturing attack normally includes various image processing attacks, it is not so easy to deal with. However, we found that color space conversion based on the RGB color space is the major element of the capturing attack. In this paper, we present experimental and theoretical results on the effect of the color conversion between RGB and YCbCr to embedded watermarks. According to our experimental results, the previous watermarking method based on the spread spectrum scheme is vulnerable to the color conversion attack. A solution to this problem is devised from the formula of the color conversion.
