What is the DoubleTake™ Personalization System (DPS)?
DoubleTake™ is a new and patented method for protecting images. The DoubleTake™ Personalization System (DPS) is an application of that method for creating personalized ID graphics that are extremely resistant to scanning, copying, and alteration.
Almost all of the printed graphic images we see around us are created in the same way. An image's colours are simplified into those which can be displayed using just three primary colours: cyan, magenta, and yellow. Black is often added as a fourth primary colour. Grade school art class taught us that mixing primary colours makes a new colour. Just like combining red and yellow makes orange, the combination of the primary colours used in printing make a rainbow of colour possible. The mechanism for mixing these primary colours is the halftone dot screen. Each primary colour is screened using a grid of dots, where the size of each dot varies in comparison to the remaining white-space. Each primary colour is treated the same way, so that when they are overlaid, they combine to convey a broad range of colours. All printed graphics, from the ultra-high-end to the stuff you print on your ink-jet printer, are created using this dot-screen system. Figures 1 and 2 illustrate the technique, often called Process Colour.

DoubleTake™ images are different. They do not use dots. Rather, DoubleTake™ screens are built from recognizable characters. They can convey any message desired, from a person's name to your grandmother's recipe for chocolate-chip cookies. Figure 3 illustrates the unique DoubleTake™ character based screens, which in this case spell the name Jane C. Dough. The DPS program can use any phrase or set of words or alpha-numeric characters to create these screens, on a customized, imageby- image basis. Each graphic image run through the DPS can be encoded with its own unique set of characters in which the images are inseparably formed.

That's Really Cool, But How Does it Provide Security?

DoubleTake™ provides security protection for images in several ways and on many levels. The initial levels offer a deterrent that opportunistic counterfeiters will find difficult to crack. The deeper levels will leave the most accomplished professional wishing they had never gotten involved, and the deepest levels will forestall assault by even the best equipped and well-funded organizations. From overt to covert to forensic, the DPS has a lot to offer. Figure 4 illustrates the construction of a photo ID card using the DPS program.
