| 摘 要： | 针对现有PDF417条码的数字水印嵌入和检测算法比较复杂、水印的嵌入强度不好控制以及对条码打印机和扫描仪的精度要求比较高等问题,提出了一种在PDF417条码的合适边缘嵌入盲水印信息的方法,将二维条码和数字水印技术相结合以提高PDF417二维条码的安全性和保密性.

| Abstract: | PDF417 is one of popular 2D BarCodeff there are some problems related to it.For example,the algorithm of embedding and examining the watermark based on the 2D BarCode is complex.The embedding intensity of the watermark is not easy to control and the current algorithm relies on bar code printers and scanners which have high precisions.Aiming on these problems,this paper proposed a method of embedding blind watermark in suitable marginal.It will combine the 2D BarCode with a watermark to improve the security and secrecy of 2D BarCode. |
