摘要： Document copying systems and methods include initiating a copy job for copying a document having document content. A log of the copy job is generated, and the document is scanned to create a document content image. The log is encoded using an input image to produce a data-bearing halftone image which is merged with the document content image. The merged data-bearing halftone image and the document content image are printed to produce a copy of the document.

摘要： A forensic verification system (900) extracts a print signature via a print signature extractor (910) from a captured image of a printed halftone. The system (900) utilizes a comparator (920) to compare the print signature to a reference signature stored in a registry to determine differences between the print signature and the reference signature. The system (900) utilizes a forensic analyzer (930) to perform a forensic analysis on the signatures based on the comparison to authenticate the printed halftone.

摘要： A forensic verification system (700) extracts a print signature via print signature extractor 710 from the boundary of a halftone contained in an image. The system (700) compares the print signature to a reference signature stored in a registry via comparator 720 to determine differences between the print signature and the reference signature. The system 700 performs a forensic-level statistical image analysis via forensic analyzer 730 on the print signature and the reference signature based on the comparison to authenticate the printed media.

摘要： A forensic verification system (1100) extracts a print signature via a print signature extractor (1110) from an interior of a halftone contained in an image. The system (1100) utilizes a comparator (1120) to compare the print signature to a reference signature stored in a registry to determine differences between the print signature and the reference signature. The system (1100) utilizes a forensic analyzer (1130) to perform a forensic analysis on the signatures based on the comparison to authenticate the image.

摘要： Document copying systems and methods include initiating a copy job (20) for copying a document (1) having document content. A log (22) of the copy job is generated, and the document is scanned to create a document content image (24). The log is encoded using an input image to produce a data-bearing halftone image (26) which is merged with the document content image (28). The merged data-bearing halftone image and the document content image are printed (30) to produce a copy (2) of the document.

摘要： 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.

摘要： A system for creating a data-bearing image can include a reference image generator configured to apply a clustered-dot halftone screen to a continuous-tone image. The resulting reference halftone image includes carrier cells in which a pixel cluster can be shifted to at least two shift positions in the carrier cell. The system also includes a payload encoder configured to segment the data payload and encode data segments into one of the carrier cells by shifting the cluster to one of the shift positions. The system also includes an output device configured to output the resulting data-bearing halftone image.
