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.
