Abstract

The invention relates to an anti-counterfeiting system used for anti-counterfeiting by matching the relationship between a micro image code and a verification code. The system comprises a micro image code recognition device and an anti-counterfeiting certificate, wherein the micro image code for representing an article to be verified and the verification code corresponding to the micro image code are printed on the surface of the anti-counterfeiting certificate; the micro image code is formed by a plurality of micro image units, different micro image codes are distinguished according to combination manners of the plurality of micro image units in each micro image code, and the micro image units are combined to form a micro graphic which cannot be recognized by human eyes; and a unique information code obtained after decoding the micro image code by the code recognition device is matched with and corresponds to the verification code printed on the surface of the anti-counterfeiting certificate.

Description

[0001] The present invention is a divisional application based on the following patent application: the application number is 200810113069.X, the application date is May 27, 2008, and the title of the invention is "method for identifying authenticity by checking miniature image codes and verification codes" ". 【Technical field】 [0002] The present invention relates to an anti-counterfeiting anti-counterfeiting system utilizing miniature image codes and verification codes to match, and in particular to an anti-counterfeiting anti-counterfeiting system that is printed with matching miniature image codes and verification codes, and checks whether the miniature image codes and verification codes match. system. 【Background technique】 [0003] In the existing anti-counterfeiting technology, the anti-counterfeiting measures adopted for documents such as ID cards and passports mainly include the following: 1) The more common method is to set a laser holographic pattern on the docum...
