This study puts forward a new idea that the Random dot stereogram and Visual Cryptography Technology and Infrared image hidden technology is combined, called a polynomial hidden anti-counterfeiting printing technology, three hidden image technology, find a common element, the Amplitude Modulation (FM). After the experiment, Random dot stereogram is complete, and the Visual Cryptography Technology, and finally processes the Infrared image hidden technology. The results of the experiment demonstrate that the combination of multiple hidden anti-counterfeiting printed techniques can be achieved, although the overall result is a little difference, the future is still There is a space with improved.
