ABSTRACT:
A method is provided for embedding dispersed miniature security marks within documents and images, utilizing a mark parameters database, graphical user interface, and detection simulator. The method includes predicting detection error rates for each pixel location of a host image, defined as a digital representation of at least one recipient of the dispersed miniature security marks, with each dispersed miniature security mark including a plurality of scattered dots. The detection error rates for each pixel are displayed with the host image on a graphical user interface and the desired dispersed miniature security mark locations are selected. At least one set of dispersed miniature security mark parameters is identified, with the parameters being mark parameters that enable determination of an optimized balance between detectability and visibility of the dispersed miniature security marks. The host image with the dispersed miniature security mark is displayed for review and adjustment by an operator.
