| 摘 要： | 综合分析了二值图像数字技术，得到可根据结构特征设计二值图像信息嵌入算法的结论。针对一类特定的二值图形——PDF417二维图形码，提出了基于边界移位的隐藏信息嵌入算法。将此算法与RS编码结合，可以在二维图形码的数字水印中得到广泛的应用。

| Abstract: | After analyzing the digital watermarking techniques for binary images, the conclusion that a successful information hiding technique must be based on the special structure of the hidden media was made. Aiming at a specific binary images PDF417 2D Barcode, a new information hiding method based on boundary shift was brought up. Being combined with RS-code, this method can be widely used in 2D Barcode digital watermarking techniques. |
