Research and implementation of fragile watermark for vector graphics
矢量图形脆弱水印研究与实现*

This paper described the methods of integrity authentication for vector graphics fistly,and then introduced digital watermarking for vector graphics.For vector graphics composed by linear entities,it proposed a fragile watermark algorithm,which was based on that the linear entities of vector graphics were divided into different groups,and watermark information was embedded in these groups.The extraction procedure not only verified the integrity of the watermarked vector graphics,but also located modificatio...
