A method and system for identifying counterfeit certificates based on a cis image acquisition system

Abstract

The invention discloses a method and system for identifying counterfeit licenses based on a CIS image acquisition system. The method includes correcting the collected license images, detecting and segmenting the reading area of ​​the license images, recognizing the surface characters of the license images, and identifying information on the license chip. Reading and authentication of license images; its system includes transmission device, CIS tube image acquisition system, main control module, ID card or passport chip reading module, host computer interface, and stored in the host computer and executed when called The computer program of the steps of the authentication method; the certificate authentication method and system of the present invention are compatible with the authentication of ID cards and passports, and have strong anti-interference ability, can meet the collection and authentication requirements of various situations, and are universal It also has multiple security protections for counterfeiting, which can improve the accuracy of counterfeiting while ensuring efficiency, and meet the needs of the technical field of certificate identification and counterfeiting.

Description

technical field [0001] The invention belongs to the technical field of certificate identification and identification, and in particular relates to a method and system for identification and identification of certificates based on a CIS image acquisition system. Background technique [0002] A passport is a legal document issued by the country to prove the nationality and identity of a citizen when he or she enters or leaves the country and travels or resides abroad. Whether at the airport or customs, a passport is a must-have document for people. The ID card is the most important ID card for everyone in the country, and it will be used no matter whether you take a train, send a courier, or fly. Therefore, it is very important to read and authenticate certificates. [0003] Existing license detection technology, such as the second-generation ID card authenticity identification method and device disclosed in the Chinese patent application number 201310355211.2, is to combine...

Problems solved by technology

[0003] Existing license detection technology, such as the second-generation ID card authenticity identification method and device disclosed in the Chinese patent application number 201310355211.2, is to combine the text information and face image stored in the ID card's built-in chip with the text information on the ID card surface and The surface face images are compared separately, and the authenticity of the ID card is judged by the difference between the similarity and the preset threshold; the authenticity of the ID card can be identified without being limited by the ID card data database, which improves the second-generation identity. However, with the emergence of more and more counterfeit documents, the clarity of the images collected by the existing license reader can no longer meet the current needs of counterfeiting, which also brings great Security risks

In the prior art, there is a technology that uses CIS tubes to collect bills, and the collection of bill images is completed by running from one end of the device to the other through the transmission device; however, the passport has more than one page, and cannot run from one end of the device to the other through the transmission device. The other end is used to collect images of passports with more than one page that need to be turned over, so it is not suitable for ID verification
