The method includes the following steps that: acquiring the information of an identity card; recognizing the information of the identity card; carrying out blacklisted identity card verification; acquiring biological characteristic information; carrying out blacklisted biological characteristic verification; carrying out biological characteristic recognition; and updating basic information in a basic information storage module. The information of the identity card itself is verified, so that the identity card itself can be a valid identity card, and therefore, the counterfeiting of the identity card can be prevented; the information of the identity card is compared with blacklisted identity cards, the biological characteristic information card of the holder of the identity card are compared with that of blacklisted people, so that the holder of the identity card can be judged, and therefore, a dangerous person can be prevented from being mixed himself or herself into ordinary people, and the safety of coming and going people can be improved; grading setting is adopted when the information of the identity card is compared with the basic information, and therefore, comparison rate can be improved; and the basic information of people is updated, so that the time interval of the acquired biological characteristic information of the holder of the identity card and the basic information of the people can be shortened, and the accuracy of biological recognition can be improved.

technical field [0001] The invention relates to the field of identity verification, more specifically, it relates to a method and system for verifying ID cards based on biological characteristic identification. Background technique [0002] In recent years, the social environment has become increasingly complex, public security and criminal crimes have occurred from time to time, especially anti-social and anti-human cases have gradually increased.

AI Technical Summary

Problems solved by technology

[0004] 1. The identity card or the identity of the card holder cannot be determined,

[0005] 2. When the time interval between shooting the ID card is long, the accuracy rate of comparing the image collected on-site with the photo stored in the ID card will decrease;

[0006] 3. Since the ID photos of all ID cards are stored in a storage library, the process of obtaining ID card information is slow
