Abstract
Engineering graph plays an important role in design and manufacture, such as architecture, machinery, manufacture, military and so on. However, almost no persons consider the security and copyright of two-dimensional engineering graph. A novel method for two-dimensional engineering graph watermark based U system is proposed in this paper. Watermarks generated by this technique can be successfully extracted even after rotated, translated, and scaling transformed.
