A Brief History of Hidden Word Technology Other methods use the traditional “big dot/little dot” technology, which was developed many years ago when only black & white copiers were readily available. Once color copiers became commonplace at every student union and corner copy shop incidents of fraud began to rise, because the higher the resolution of the copier, the less effective “big dot/little dot” becomes. Our patented method Optical Deterrent Technology™ (ODT™), was specifically designed to work on color copiers and scanners. Since black & white transcipts are never accepted as official, it is critical that you use a method proven to work on the copiers that pose the greatest threat to your transcript security. |

Why is Today's technology can provide anybody the tools necessary to fraudulently duplicate and alter any transcript document. Optical Deterrent Technology™ (ODT™) is a patented security feature that forces a hidden word to appear when a transcript is copied or scanned. ODT™ works with a high degree of effectiveness in protecting your transcript from unwanted duplication and alteration on today's color copiers and scanners. ODT™ can be fully customized to fit your layout with the hidden word of your choice. Our standard paper contains a built-in chemically reactive security feature. ODT™ is the best hidden word deterrent feature on the market today! Even high resolution digital cameras are no match for ODT! |
