Enhanced security printing of a layout template

摘要

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.
