    • A method of authenticating a document includes providing a document having a substrate comprising an optical brightener; printing a background with a ultraviolet (UV) absorbing material on the substrate comprising a first pattern of lines having a first frequency and a first orientation; printing a security mark with the UV material on the substrate comprising a second pattern of lines having a second frequency or a second orientation or both; placing a lenticular lens over the security mark and background; illuminating the security mark and background through the lenticular lens with UV light; orienting the lenticular lens to match either the first orientation or the second orientation; and authenticating the document if the security mark matches a predetermined security mark.
    • 认证文件的方法包括提供具有包括荧光增白剂的基底的文件; 在衬底上用紫外线(UV)吸收材料印刷背景,包括具有第一频率和第一取向的线的第一图案; 用衬底上的UV材料印刷安全标记,其包括具有第二频率或第二取向或两者的第二线条图案; 将双凸透镜放在安全标记和背景上; 用紫外线照射透镜透镜的安全标记和背景; 定向双凸透镜以匹配第一取向或第二取向; 并且如果安全标记与预定的安全标记相匹配,则认证文档。

    • A method for authenticating an object that includes providing a label (12) with invisible indicia (14) printed with optically active material on a reflective substrate; providing a device that has a digital camera (18) having a light source (20), an image sensor (22), a first polarizing filter (24) having a first orientation, and a second polarizing filter (26) having a second orientation; illuminating the label with the light from the light source through the first polarizing filter; forming an image with the image sensor using reflected light from the label wherein the reflected light passes through the second polarizing filter prior to reaching the sensor; wherein the second polarizing filter makes the invisible indicia visible; and authenticating the object.
    • 一种用于认证对象的方法,包括在反射基板上提供标有印有光学活性材料的不可见标记(14)的标签(12) 提供一种具有数字照相机(18)的装置,其具有光源(20),图像传感器(22),具有第一取向的第一偏振滤光器(24)和具有第二取向的第二偏振滤光器(26) ; 用来自光源的光通过第一偏振滤光器照射标签; 使用来自标签的反射光与图像传感器形成图像,其中反射光在到达传感器之前穿过第二偏振滤光器; 其中所述第二偏振滤光器使所述不可见标记可见; 并验证该对象。
