Second-generation identity card-based authentication method and system

Abstract

The invention provides a second-generation identity card-based authentication method and a second-generation identity card-based authentication system. The method comprises the following steps of: A, reading an image stored in a built-in anti-counterfeiting chip of a second-generation identity card to obtain a first image, and performing image acquisition on the face of a card holder to obtain a third image; B, scanning a photo printed on the surface of the second-generation identity card to obtain a second image; C, judging whether similarity between the first and second images is more than or equal to a first preset threshold or not by utilizing a face recognition technology, executing a step D if the similarity between the first and second images is more than or equal to the first threshold, otherwise outputting authentication failure information; and D, judging whether the similarity between the second and third images is more than or equal to a second preset threshold or not by utilizing the face recognition technology, outputting authentication success information if the similarity between the second and third images is more than or equal to the second threshold, otherwise outputting the authentication failure information. By the method and the system provided by the invention, the reliability and efficiency of authentication can be improved.

Description

technical field [0001] The invention relates to image recognition technology, in particular to a method and system for identity verification based on a second-generation ID card. Background technique [0002] At present, my country's second-generation ID cards have been widely popularized. Since the second-generation ID card has a built-in anti-counterfeiting chip, the anti-counterfeiting chip can provide a certain amount of storage space for storing the photo of the cardholder, laying a good foundation for the electronic application of the second-generation ID card. [0003] As a special certificate, the second-generation ID card is mainly used to verify the identity of the holder, and this verification process includes two important links. The first link is the authenticity of the second-generation ID card itself. The second link is the consistency between the second-generation ID card and the holder; among them, the first link can be realized through anti-counterfeiting ...

AI Technical Summary

Problems solved by technology

Since the assistance of relevant staff is needed in the authenticity verification process of the second-generation ID card and the consistency verification process between the second-generation ID card and the cardholder, the reliability of the entire verification process depends on the experience and experience of the staff. The recognition ability is closely related, and the reliability of verification needs to be improved

In addition, some counterfeiters can further reduce the reliability of the second-generation ID card by falsifying the photos on the surface of the second-generation ID card and various anti-counterfeiting marks.

[0005] With the popularization and application of the second-generation ID card, more and more occasions need to accurately verify the identity of the card holder in a short period of time, which puts forward higher requirements for the reliability and efficiency of identity verification. , such as airport security checks, large-scale conference security checks, etc., but in the existing methods of identity verification based on second-generation ID cards, the reliability and efficiency of identity verification are limited due to the need for assistance from relevant staff during the entire identity verification process. Sexuality needs to be further improved
