ABSTRACT
Digital watermarking is an effective way to achieve copyright protection. For the current application limitations in fractal image watermarking by using 0, 1 serial number as a watermark, this paper propose a fractal theory and XML technology combined digital watermark technology. The watermarking algorithm FXBWM, include the watermark embedding algorithm FXBWM-EM and the watermark detection algorithm FXBWM-DT. The LAB color space is used instead of the RGB color space which is found to be more suitable for watermarking application. Experimental results indicate that compare to the traditional watermarking algorithms, the watermark embedding and detection process is fast and the FXBWM algorithm can achieve the meaningful watermark embedding without compromising the image quality and watermark robustness. This is also a new direction in XML technology for digital watermarking.
