These days, non-professional users can manipulate digital videos easily with a video editing tool. Owing to this situation, many digital videos are distributed illegally in irregular form. In this paper, we propose a dual digital watermarking system which can estimate the distorted region of digital videos to resolve copyright infringement problems. The proposed system can identify geometrical and temporal distortions.
