A system that hides information in a customer supplied graphic. The apparatus of this invention provides a device for verifiable security in a postage meter or other devices using dot or drop printing. Security is achieved by counting the number of signal pulses that are used to produce ink drops or ink dots that are required to reproduce the customer supplied graphic. The aforementioned may be accomplished by adding a smart module to digital print head modules. The smart module would capture driver pulses from the print head module and interpret the pulses associated with regions of the graphic. Thus, the smart module would take data from the printer controller that is used to cut off printing when the ink is consumed and relate “set” values to the drops produced during the production of the graphic or portions of the graphic, thereby linking the postal value printed in the indicia to the information hidden in the graphic or portions of the graphic.
