    摘要: A reading device reads ambiguous target elements of an authentication target printed on a medium. Each ambiguous target element has a number of different manners by which the ambiguous target element can be interpreted by the reading device. The authentication target as read by the reading device is compared against an authentication signature of the reading device. The authentication signature specifies for each ambiguous target element an expected manner by which the reading device interprets the ambiguous target element as one of the different manners by which the ambiguous target element can be interpreted. Where the authentication target as read by the reading device matches the authentication signature of the reading device, the reading device is signaled as having passed authentication.

    摘要: A method and system for generating a document having a void pantograph highlight pattern is presented. The method includes computing a score for a void pantograph highlight pattern layer in relation to a document formatted content layer, incrementing a relative position of the void pantograph highlight pattern layer and the document formatted content layer, repeating the computing and the incrementing steps to obtain a plurality of scores at a plurality of relative positions, evaluating the plurality of scores to determine an optimal alignment, and printing the document using variable-data printing techniques, wherein the printed document has a multi-layer architecture including the document formatted content layer and the void pantograph highlight pattern layer. The system includes a control processor, a score computation unit and an evaluation unit. The control processor provides a printer with data containing a multi-layer architecture document having a document formatted content and a void pantograph highlight pattern.

    摘要: A printed information device includes a region of interest in an image, and at least two channels assigned to the region of interest by different means of logical partitioning. The region of interest represents a physical area of the image. Each of the channels has a different error tolerance. Continuous and/or cyclic information is independently encoded in each of the at least two channels. The deterrent is configured to be read substantially simultaneously by at least two distinct reading strategies.

    摘要: A multiple resolution readable color array printed for labeling or displayed electronically achieves readable data at multiple optical resolutions. The array has a hierarchy of cells, where cells at a lower level of resolution include spatially adjacent smaller cells at a higher level of resolution. Colors are encoded in redundant cells within the hierarchy so that overall color assigned to a lower resolution cell depends on the colors encoded in the included data cells at a higher resolution.
