Embodiment Construction

[0024] In order to further explain the technical means and effects adopted by the present invention to achieve the intended purpose, the specific implementation method, Structure, characteristic and effect thereof are as follows in detail.

[0025] see figure 1 As shown, it is a structural block diagram of the miniature image coding anti-counterfeiting system of the present invention. The miniature image coding anti-counterfeiting system includes a miniature image coding identification device and an anti-counterfeiting certificate. The miniature image code printed on the certificate is in one-to-one correspondence with the attributes of different items to be inspected. The above miniature image code recognition device includes: an optical module for obtaining a microscopically enlarged optical image on the surface of the anti-counterfeiting certificate; an image sensor for generating a digital image from the optical image obtained by the optical module; Pick up the miniature...

Abstract

The invention relates to an anti-counterfeit certificate printed with a micro image code. The surface of the anti-counterfeit certificate is printed with the micro image code corresponding to the attribute of an article to be checked. The micro image code comprises a plurality of micro image units, different micro image codes are distinguished by the combination mode of the micro image units in every micro image code, and the micro image units are combined and form micro patterns which can not be identified by human eyes; a verification code obtained by the micro image code through unique decoding corresponds to the attribute of the article to be checked. The invention adopts a mode of directly reading the micro image code printed on the surface of the anti-counterfeit certificate to carry out check, so that the invention has high identifying speed and completes the check work of a great deal of articles to be checked in a shorter period.

Description

【Technical field】 [0001] The invention relates to an anti-counterfeit certificate printed with a miniature image code, in particular to an anti-counterfeit certificate printed with a miniature image code, which can identify the authenticity of an inspection item. 【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 th...
