摘　　要：针对运用数字化智能检测应用于防伪识别的重要性与复杂性,基于龟纹产生的光学机理以及防伪码设计的再现原稿信息和唯一数据样本原则,提出了二维防伪码的新设计方案。首先将原稿的图像信息傅里叶变换转化成函数值输入系统,经过RIP绘制各值拟合的贝塞尔曲线,用Visual Basic以函数的形式输出图像信息,最后应用于印刷品,提升了防伪码的可信度,为防伪标记的设计和智能检测提供了新思路。In view of the importance and complexity of the digital intelligent detection used in anti fake recognition mechanism,optical moire arise and the reappearance of the original information and the only sample data security code based on the design principle,puts forward a new design scheme of two-dimensional code.First the image information of Fourier transform the original into a function value input system,through the RIP drawing the value of Bessel curve fitting,using Visual Basic to form the output image information function,finally the application of printed matter.To enhance the credibility of the security coding,provided a new design thinking and intelligent detection of anti fake mark.
