Flash Animation Watermarking Algorithm Based on SWF Tag Attributes

This paper presents a Flash animation watermarking algorithm based on SWF tag attributes. First, the SWF file is converted into an XML file, and the watermark image is converted into a binary data stream. Second, filter and categorize the tags and their attributes that have minimal effect on the animation in the XML file, and embed the binary data stream into the XML file according to a certain sequence of tag attributes. Finally, the XML file embedded in the watermark information is converted into a SWF file. Experiments show that the algorithm proposed in this paper has good transparency and invisibility, and it has the characteristics of high hiding capacity.
