基于微结构网点的信息隐藏防伪技术研究

摘要

The improved screening method is proposed based on screening with threshold matrix and with the artistic dot with micro-structure anti-counterfeiting function designed,using the technology of dot hiding information hide information and investigating its potential application in information hiding.Test results show that the combination of dot security and the information hiding security could achieve better visual secret effect;under the condition of almost no increase in cost,the technical level of security and the added value of the product are improved.%对基于阈值矩阵的加网方法中的阈值矩阵进行改进，设计出具有微观防伪功能的艺术型网点，利用半色调信息隐藏技术进行信息隐藏，研究其在半色调信息隐藏技术中潜在的应用价值。实验结果表明，将信息隐藏防伪和网点结构防伪结合，可使信息隐藏达到更好的视觉保密效果，在不增加成本的条件下提高了防伪技术水平和产品附加价值。
