摘　　要：分析了二维码的防伪原理,提出了在可变数据印刷中应用二维码进行防伪的方案,在完成基于可变数据印刷的二维码的生成和识别实验的基础上,设计实验比较得出了不同二维码(PDF417码与QR码)的防伪特性的差异。理论分析及实验结果表明,利用二维码对可变数据印刷进行防伪的方案是可行的,并且不同二维码的防伪特性存在差异,在实际应用中可以根据具体的要求选用不同的二维码。The principle of two-dimensional bar code anti-counterfeiting technology was analyzed.A plan of applying two-dimensional code anti-counterfeiting technology in variable-data printing was put forward.On the basis of experiments on generation and recognition of two-dimensional bar code,anti-counterfeiting properties of two different two-dimensional bar codes（PDF417 code and QR code） were obtained and their difference was compared.The theoretical analysis and experiment results showed that anti-counterfeiting technology based on two-dimensional bar code can be used in variable data printing,besides,different two-dimensional bar codes have different anti-counterfeiting properties;different two-dimensional bar code should be selected according to specific requirements.
