A method of 2D BarCode anti-counterfeit based on the digital watermark

FU Ming1,HE Ye1,LIU Hong2(1.School of Computer and Communication Engineering,Changsha University of Science & Technology,Changsha 410076,China;2.Hunan Branch Center of China Article Encoding Center,Changsha 410007,China)  
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.
