Micro image code recognition device matched with anti-counterfeiting certificate

Abstract

The invention relates to a micro image code recognition device matched with an anti-counterfeiting certificate. The micro image code recognition device comprises an optical module, an image sensor, an image recognition and processing unit, an output unit and a control module, wherein the optical module is used for obtaining a microscopically-amplified optical image on the surface of the anti-counterfeiting certificate; the image sensor is used for generating the optical image obtained by the optical module to a digital image; the image recognition and processing unit is used for picking up a micro image code from the digital image generated by the image sensor and decoding the micro image code to a unique information code corresponding to the micro image code; the output unit is used for outputting the information code obtained after the micro image code is decoded; and the control module is used for receiving the information codes output by the image recognition and processing unit and controlling the output unit to output the information code.

Description

[0001] The present invention is a divisional application based on the following patent application: the application number is 200810113068.5, the application date is May 27, 2008, and the title of the invention is "anti-counterfeiting certificate for authenticity identification by checking micro-image coding and verification code". 【Technical field】 [0002] The invention relates to an anti-counterfeit system for identifying authenticity by checking micro-image codes and verification codes, in particular to a micro-image code identification device matched with an anti-counterfeit certificate. 【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 document, which uses human eyes to identify anti-counterfeiting signs. The disadvantage is that as long as similar equipmen...
