） 摘要： 面对开放的网络环境和便捷的信息处理技术
提出了一种应用长度比例变换算法实现数字水印的嵌入
） Abstract： In the face of on-limits internet and technology of information disposal, the problems of copyright protect and information security become more and more salient
It is necessary to solve the problems at once
As one of the most potential technology, the figure watermark has used widely
So it becomes a hotspot of copyright and tortuous survey
From the early airspace to commutation area and based on physical model, the disquisitive extension has developed widely
There are many typical arithmetic, attack instruments and evaluating benchmarks of figure watermark
Aim at lots of lines, circles and arcs in engineering chart, the commutation arithmetic of length and scale is one of the most effective arithmetic
At last, it set out some problems of figure watermark in engineering chart and expectation of the direction and points in future
