CIS image collection system-based certificate authenticity identification method and system

Abstract

The invention discloses a CIS image collection system-based certificate authenticity identification method and system. The method comprises the steps of correcting a collected certificate image; detecting and segmenting a certificate image reading region; identifying surface characters of the certificate image; reading certificate chip information; and identifying the authenticity of the certificate image. The system comprises a transmission apparatus, a CIS tube image collection system, a main control module, an identity card or passport chip reading module, an upper computer interface, and acomputer program stored in an upper computer and used for executing the steps of the certificate authenticity identification method when being called. The certificate authenticity identification method and system is compatible with identity card and passport authenticity identification, has a strong anti-jamming capability, can meet collection and authenticity identification demands in multiple conditions, is wide in universality and applicability, has multiple security protection authenticity identification, can improve the authenticity identification accuracy under the condition of ensuringthe efficiency, and meets the demands in the technical field of certificate reading and authenticity identification.

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
