ABSTRACT:
A method for protecting content of vector graphics formats is provided. A first vector graphics is scrambled to generate a second vector graphics. Then a plurality of pixel samplings are performed by the first vector graphics which generating at least a recovery information object according to a predetermined graphics. The predetermined graphics is watermarked to generate a watermark object. And the recovery information object is encoded and embedded in the watermark object to generate a recovery information watermark. Finally, the second vector graphics, the recovery information watermark, and the recovery code are combined to generate a protected first vector graphics.
