Certificate authenticity verification method and device, computer equipment and storage medium

Abstract

The invention discloses a certificate authenticity verification method and device, computer equipment and a storage medium. The certificate authenticity verification method comprises the following steps: acquiring image information of the target certificate at different continuous shooting angles, and performing feature detection on the image information at each shooting angle to obtain a plurality of continuous feature information, the feature detection including performing color-changing ink value detection on an optical color-changing ink area in the image information, and the feature information including a color-changing ink value; calculating a difference value between every two adjacent color-changing ink values and taking absolute values to obtain a plurality of color-changing inkabsolute values; judging whether a first color-changing ink absolute value greater than a preset color-changing ink absolute value exists in the plurality of color-changing ink absolute values or not;and if so, outputting the information that the target certificate is true. The certificate authenticity verification method can solve the problems of low efficiency and low accuracy of manual verification of identity card authenticity in the prior art.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a certificate authenticity verification method, device, computer equipment and storage medium. Background technique [0002] As a legal document to prove the personal identity of citizens, ID cards play a very important role in application scenarios such as banks, customs, airports, and railway stations. More and more occasions have raised the issue of the efficiency and accuracy of ID card verification. higher requirements. [0003] In the prior art, in order to verify the authenticity of the ID card, it is generally necessary for relevant staff to compare the consistency of the information read from the chip with the information derived from the identity information database, or use the information read from the chip to Face photos and photos printed on the surface of the ID card are similarly compared to determine the authenticity of the ID card. Most of the verif...
