Application of the digital watermarking technique in 2-D barcode certificate anti-counterfeit systems

摘要：

At present, two dimensional barcode has been used in many fields. The safety of information in barcode is important, so this article brings up an effective two dimensional barcode encryption technology to assure it. Either two-dimensional barcode or digital watermarking technique is one of the most important parts and research focuses in anti-counterfeit fields. This paper designs and realizes a whole set of certificate administration system based on QRcode. On this platform the digital watermarking technique based on the spatial domain is used to encrypt the two dimensional barcode. The combination of two dimensional barcode and digital watermarking can improve the security and secrecy of personal information, and realize real anti-counterfeit certificates.
