摘要： A method of eliminating background noise from a system for authenticating security markers includes capturing an image of a background of the security marker; illuminating the security marker; capturing a plurality of images of the optical response of the security marker; averaging the plurality of optical response images; smoothing the background image; and subtracting the smoothed background image from the average of the plurality of optical response images.

摘要： A labeling method for marking a product with invisible information. The label includes a removable laminate formed from a light transmissive layer, and a light transmissive adhesive that detachably affixes the label to a product. The label includes an invisible marker that contains information, detectable by light of selected wavelength. The amount of marker selected is sufficient to allow information in the marker to be detected only when the laminate is affixed over a surface with a selected optical background. The label laminate is removed from the surface of the product and affixed to a surface having the selected optical background and is exposed to light that renders the information in the marker detectable. The method allows covert information in the label laminate to be reliably detected and read with the use of minimal quantities of marker material.
摘要翻译：用不可见信息标记产品的标签方法。该标签包括由透光层形成的可移除层压材料，以及将标签可拆卸地粘贴到产品上的透光粘合剂。该标签包括一个不可见的标记，其中包含可通过所选波长的光检测的信息。选择的标记的量足以仅当层压体被固定在具有所选光学背景的表面上时才能检测标记物中的信息。将标签层压材料从产品的表面去除并固定到具有所选光学背景的表面上，并暴露于使标记中的信息可检测的光。该方法允许使用最少量的标记材料可靠地检测和读取标签层压板中的隐蔽信息。
