Digital watermarking technology can be applied to reference services that provide digital information related to pictures taken by mobile phone cameras. Conventional reference services for mobile phones are designed for still images and detect watermarks from single pictures. We propose a video watermarking scheme for fast, robust detection to develop a reference service for video. To handle spatial synchronization, the scheme uses the rectangular tracking technique, and to provide temporal synchronization and robustness against noise, it uses the watermark technique based on the SFPSS method. We also introduce a quantitative evaluation method to determine reliability of the detection results. Finally, we evaluate the scheme's implementation on a mobile phone and demonstrate its efficiency.
