Abstract

The invention relates to a method for genuine or counterfeit identification by identifying a micro image code, comprising the following steps: an anti-counterfeit certificate which is matched with an article to be checked is arranged, and the surface of the anti-counterfeit certificate is printed with the micro image code; a corresponding table is generated and is stored in a storage unit; an optical module obtains a microscopically magnified optical image on the surface of the article, and an image sensor generates the optical image into a digital image; an image identification processing unit checks whether the micro image code exists in the digital image or not; if the micro image code exists in the digital image, the micro image code is picked up and is decoded into a verification code uniquely corresponding to the micro image code, and a control module looks up the attribute of the article which is to be checked and corresponds to the verification code obtained by decoding in the corresponding table; and if the control module looks up the attribute of the article which is to be checked and corresponds to the verification code in the corresponding table, the attribute of the article to be checked is output and is used for genuine or counterfeit identification of the article to be checked.

Description

【Technical field】

[0001] The invention relates to a method for identifying the authenticity of miniature image codes, in particular to a method for identifying the authenticity by identifying the miniature image codes. 【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 to the level. The disadvantage is that it is easy to leak secrets. The anti-counterfeiting method adopts the common anti-counterfeiting method. If one p...
