Abstract:
A variable data addition method and system are disclosed herein. The method includes generating an original image, and defining at least one sub-section of the original image to transform individually. A reversible transformation is applied to the defined at least one sub-section, thereby altering the original image to form an altered image that is non-readable until an inverse of the reversible transformation is applied to the altered image.
Abstract:
A method for model-based signature profile extraction includes capturing an image of an authentic glyph. An outline model is fit to the image of the authentic glyph, and an authentic signature profile is extracted based on the outline model. A signature profile extracted from an image of another glyph may be compared to the to the authentic signature profile so as to forensically verify authenticity of the other glyph The system for model-based signature profile extraction includes a controller, a capture unit, an outline unit, a profiling unit, and a forensic verification unit. A computer readable medium containing executable instructions is also described.
Abstract:
A counterfeit detection system is disclosed herein. The system includes an image reduction system for minimizing size of at least one original image using a plurality of different reduction strategies to generate a plurality of minimized images. The system further includes a classification system which includes a first sub-system for generating at least one accuracy comparative assessment metric for each of the plurality of minimized images, a second sub-system for comparing the at least one accuracy comparative assessment metric for each of the plurality of minimized images with an accuracy assessment metric for the at least one original image, and a third sub-system for determining if at least one of the plurality of minimized images can be transmitted with improved or equivalent classification accuracy at a reduced bandwidth when compared to the original image are also part of the system.
Abstract:
A method for decoding information from a physical image having a plurality of payload patches includes generating a digital representation of the physical image. A plurality of regions are mapped to the plurality of payload patches in the digital representation. A scramble pattern is identified and the plurality of mapped regions of the digital representation are reordered according to the identified scramble pattern. Information is decoded from the payload patches of the reordered plurality of mapped regions.
Abstract:
A method for using void pantographs involves generating a test sheet including multiple void pantographs, where each of the multiple void pantographs includes a pantograph foreground and a pantograph background. The test sheet is printed, and from the printed test sheet, at least one of the multiple void pantographs having a covert or semi-covert pantograph foreground and background is identified. The printed test sheet is scanned, and from the scanned test sheet, at least one of the multiple void pantographs having an overt pantograph foreground is identified. A workflow is developed for the at least one of the multiple void pantographs having both i) the covert or semi-covert pantograph foreground and background after printing, and ii) the overt pantograph foreground after scanning.
Abstract:
A void pantograph and a method for generating the same are disclosed herein. The void pantograph includes a foreground portion based on a region of an image that is defined using a predetermined filter, and a background portion based on another region of the image that is defined using the predetermined filter.
Abstract:
A method for enhancing security printing of a layout template is disclosed. The method includes receiving the layout template, and acknowledging one or more constraints for the layout template. At least one unconstrained layout element of the layout template is varied, thereby generating a varied layout template. The varied layout template is printed and scanned. The method further includes determining a number of bits that can be encoded in the varied layout template, where the number of bits depends on the varying of the at least one unconstrained layout element.
Abstract:
A blur resistant barcode is disclosed. The blur resistant barcode comprise a plurality of parallel lines and spaces where information is encoded in the barcode by variations in the thicknesses of the plurality of parallel lines and by variations in the spacing between the plurality of parallel lines. The blur resistant barcode has at least one blur resistant feature that has a thickness in an axis of motion greater than a maximum thickness of any one of the plurality of parallel lines. The axis of motion is perpendicular to the plurality of parallel lines.
Abstract:
Various multi-modal security deterrents (10) and methods of generating the same are disclosed herein. One embodiment of the deterrent (10) includes first and second sets (12, 16) of 180° phase-insensitive glyphs (14). One or more of the glyphs (14, Gi8o) in the second set (16) are rotated 180° from corresponding glyphs (14, G0) in the first set (12) such that the sets (12, 16) of glyphs (14) have an identical signature pollable by a suitable transmitter/receiver operating in the GHz-THz range and such that the sets (12, 16) of glyphs (14) have a different visual appearance. Data is encoded in one or more of the glyphs (140 of the first set (12) and one or more of the glyphs (14) of the second set (16) such that each set encodes a different message.
Abstract:
The present disclosure is directed to method and systems of sorting print jobs for assignment to a plurality of printers having different printing characteristics. Print jobs can be received, sorted based on the print parameters of the print jobs, combined into print job groupings based on printing prioritizations, and sent to a plurality of printers having printing configurations that achieve the print parameters and the printing prioritizations.
