METHOD FOR PROVING TRUE ARTICLE

摘要

PURPOSE: A method for proving a true article is provided to discriminate the true/false of the article by comparing a microstructure registered/linked to the same artificial information with the random microstructure of a proof card. CONSTITUTION: The proof card has the random microstructure. The information for the random microstructure is registered to a computer by linking with the artificial information. When the artificial information discriminate the true/false of the same proof card, the true/false is discriminated by comparing the information for the microstructure linked/registered to the same artificial information with the information for the microstructure formed on the target proof card.
