数字水印技术中基于SVG标签特性的哈希归类算法设计

Design of Hash Classification Algorithm Based on SVG Tags in Digital Watermarking Technology

本文在分析了SVG特性的基础上,从SVG是XML的一种扩展的角度出发,利用这个特性将标签或属性值通过哈希函数散列到不同的值中,然后将散列值对应位的水印信息嵌入的SVG文档中,提出了一种新的基于标签归类的SVG数字水印算法。

On the basis of analyzing the characteristics of SVG,from SVG is an extension of XML.Use this feature to hash a label or attribute value to a different value by hash function,then the hash value corresponding to the watermark information embedded in the SVG document,a new SVG digital watermarking algorithm based on label classification is proposed.
