基于分形技术的防伪方法

THE ANTI-COUNTERFEITING METHOD BASED ON FRACTAL

商品包装防伪在商品的整个生产销售过程中占有重要的地位,简单可行的防伪技术能够最大程度地降低生产厂家的损失,保护消费者的权益.目前市场上运用最广泛的防伪技术是高壁垒防伪技术,但该技术成本高且容易被仿造.针对以上问题,本文提出了一种基于分形技术的防伪方法.该方法首先利用分形技术生成防伪图标,同时为每张分形图生成一张对应的二维码.消费者通过扫描二维码,对比查看两幅图片是否一致就能知道商品真伪.本文方法利用分形图对参数敏感并且难以复制仿造的特点有效生成商品商标,能够有效提高防伪水平.实验证明,使用基于分形技术的方法进行防伪,仿造难度大、防伪效果明显,具有广阔的前景.

Forgery prevention plays an important role in the whole process of production and sales. Simple and feasible anti - counterfeiting method can protect consumers＂ interests and reduce the manufacturer＇ loss. At present, the most widely used method is the High Barrier Technology. However, it is costly and easy to be imitated. This paper propose an anti - counterfeiting method based on fractal technology. First, we generate the fractal graph. At the same time, a corresponding two - dimensional code is generated for each fractal graph. second, Consumers scan the two - dimensional code and receive a fractal graph. Then the Authenticity of goods can be known by comparing this graph with the picture which is printed on the package. The fractal graph, which is parameter sensitive and difficult to replicate, can improve the anti -counterfeiting quality effectively. Experiments show that the method based on fractal technology is effective and has a broad prospect.
