Abstract: A document contains a security element that combines a correlation mark and pantograph mark. The pantograph mark includes a dot pattern, part of which is printed to correspond to foreground pixels of the correlation mark, and another part of which is printed to correspond to background pixels of the correlation mark.
Abstract translation: 文档包含一个组合相关标记和受电弓标记的安全元素。 受电弓标记包括点阵图形，其一部分被打印以对应于相关标记的前景像素，并且打印其另一部分以对应于相关标记的背景像素。

Abstract: A document contains a security element that combines a correlation mark and microgloss mark so that foreground pixels of the correlation mark are printed in a toner of a first color, and pixels of the correlation mark overwrite portions of the correlation mark in a second color, but neither the first color nor the second color appear on areas that correspond to background pixels of the correlation mark.
Abstract translation: 文档包含组合相关标记和微距标记的安全元件，使得相关标记的前景像素被打印在第一颜色的调色剂中，并且相关标记的像素以第二颜色覆盖相关标记的部分，但是 第一颜色和第二颜色都不对应于相关标记的背景像素的区域上。

Abstract: A system generates a secure barcode by: identifying a primary pattern for a two-dimensional barcode to be printed on a substrate, wherein the primary pattern comprises of a set of dark cells and a set of light cells; identifying a two-dimensional micro-shape, wherein the micro-shape has a size that is no larger than a size of each cell of the two-dimensional barcode; generating a secondary pattern comprising a plurality of the micro-shapes; and superimposing the secondary pattern with the primary pattern for the two-dimensional barcode to yield a secure barcode. The resulting two-dimensional barcode includes a primary pattern comprising a set of dark cells and a set of light cells, where the sets represent encoded data, along with a secondary pattern of micro-shapes that are superimposed with the primary pattern.
Abstract translation: 系统通过以下方式产生安全的条形码：识别要印刷在基板上的二维条形码的主图案，其中所述主图案包括一组暗单元格和一组光单元; 识别二维微形状，其中所述微形状的尺寸不大于所述二维条形码的每个单元的尺寸; 产生包括多个所述微型的次级图案; 并且将二次图案与用于二维条形码的主图案叠加以产生安全的条形码。 所得到的二维条形码包括包括一组暗单元格和一组光单元的主图案，其中所述组表示编码数据，以及与主图案叠加的微形二次图案。
