摘要:
A method and apparatus for determining a digital signature from an article made of paper, cardboard, plastic or many other material types. A coherent light source directs a beam to illuminate the article and a detector arrangement collects data points from light scattered from many different parts of the article to collect a large number of independent data points, typically 500 or more. By collecting a large number of independent signal contributions specific to many different parts of the article, a digital signature can be computed that is unique to the area of the article that has been scanned. This measurement can be repeated whenever required to test authenticity of the article. Using this method, it has been discovered that it is essentially pointless to go to the effort and expense of making specially prepared tokens, since unique characteristics are measurable a in a straightforward manner from a wide variety of every day articles.
摘要(中):
一种用于由纸,纸板,塑料或许多其他材料类型制成的物品确定数字签名的方法和装置。 相干光源引导光束照射物品,检测器装置从物品的许多不同部分散射的光收集数据点,以收集大量独立数据点,通常为500或更多。 通过收集特定于文章许多不同部分的大量独立信号贡献,可以计算出已被扫描的文章区域唯一的数字签名。 当需要测试文章的真实性时,可以重复该测量。 使用这种方法,已经发现,由于独特的特征是可以从各种各样的每一天的文章中直接的方式来衡量的,所以去做特别准备的令牌的努力和费用基本上是毫无意义的。
