Abstract

The invention relates to a method for genuine or counterfeit identification by checking a micro image code and a verification code, comprising the following steps: the surface of an anti-counterfeit certificate is printed with the verification code representing an article to be checked and the micro image code matched with the verification code; an optical module obtains a microscopically magnified optical image on the surface of the anti-counterfeit certificate, and an image sensor generates the optical image into a digital image; an image identification processing unit checks whether the micro image code exists or not from the digital image generated by the image sensor; if the micro image code exists in the digital image, the micro image code is picked up and is decoded into an information code uniquely corresponding to the micro image code, and a control module controls an output unit to output the information code; the information code output by the output unit is compared with the verification code printed on the surface of the anti-counterfeit certificate; if the information code is matched with the verification code, the anti-counterfeit certificate is true, otherwise, the anti-counterfeit certificate is counterfeit.

Description

【Technical field】 [0001] The present invention relates to a method for identifying the authenticity by checking the miniature image code and the verification code, in particular to a kind of printed matching miniature image code and verification code, and verifying the authenticity by checking whether the miniature image code and the verification code match Methods. 【Background technique】 [0002] 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 document, which uses human eyes to identify anti-counterfeiting signs. The disadvantage is that as long as similar equipment can be used for imitation and forgery, it is impossible to distinguish between true and false, not only the anti-counterfeiting function is not strong, but also the cost is extremely high; The point level is managed according t...
