样条函数在防伪图标隐藏技术中的应用研究

Research and application of hidden anti_counterfeiting mark based splines

本文提出了一种防伪图标隐藏方案,对于用Beta样条曲线形成的隐藏图形,通过调整Beta样条曲线中特有的形状参数β1和β2的值,使得图像随之发生变化,从而使系列产品上的防伪图标有所区别。将Beta样条形成的图像与二值图像隐藏算法相结合,使防伪图标的安全性得到更大的提高。实验证明该算法的有效性。

A new hiding method of anti_counterferiting mark is introduced in the paper.The hidden image shaped by Beta_splines can be modified by adjusting the shape parameters of Beta_spline, thus a series of products mark are changed, The security of anti_counterfeiting mark is improved. Experimental results demonstrate the efiectiveness of the method.
