Abstract
A kind of invisible two-dimensional codes anti-counterfeit method of credentials, the method for anti-counterfeit, a width image in 2 D code is made of two-dimension code anti-counterfeit information first, then image in 2 D code is printed on the blank area of certificate with color ink using metamerism, a kind of invisible two-dimensional codes image is generated in the blank area of certificate, show blank image in the blank area of certificate under visible light, show image in 2 D code under infrared light, it is obtained by scanning correct two-dimensional barcode information, certificate can be identified in this way with the presence or absence of personation infringement problem.
Description
Technical field:
The present invention relates to a kind of anti-counterfeit method of credentials, especially a kind of invisible two-dimensional codes anti-counterfeit method of credentials, the certificate false proof skill
Art can be used in the anti-counterfeit printing of various certificates.
Background technique:
Certificate serves to demonstrate how the certificate and file of identity, experience etc., such as resident identification card, passport, employee's card, student's identity card, finishes
Industry card etc., the fraud of various forms of certificates has given society and the people to bring serious threat, and certificate false proof technology is main
There are digital encryption, digital watermarking, laser anti-false sign, cipher counterfeit-proof labeling, texture anti-fake, biological identification technology etc., with
The development of science and technology, certificate forge means also in the continuous improvement, and simple certificate false proof technology is no longer satisfied certificate
Anti-fake needs, it is necessary to constantly promote certificate false proof technology, society and the legitimate interests of the people could be protected, maintain the steady of society
Fixed and safety.
Summary of the invention:
In order to improve the reliability and safety of certificate false proof, the present invention is for deficiency existing for existing certificate false proof to existing card
Part anti-counterfeiting technology is improved, and a kind of invisible two-dimensional codes anti-counterfeit method of credentials, the method for anti-counterfeit, first by two dimensional code are proposed
Anti-counterfeiting information constitutes a width image in 2 D code, then image in 2 D code is printed on to using metamerism with color ink the sky of certificate
On white area, a kind of invisible two-dimensional codes image is generated in the blank area of certificate, shows blank in the blank area of certificate under visible light
Image shows image in 2 D code under infrared light, is obtained by scanning correct two-dimensional barcode information, can reflect in this way
Other certificate is with the presence or absence of personation infringement problem.
Metamerism typically refers to yellow black four member ink sets of green product into one group of ratio match with color ink, this group of ink exists
It is seen that identical color, i.e., homochromy under visible light；And under infrared light because yellow black four color ink of green product match different productions
The spectral difference that adds lustre to is different to show different colors, i.e., different spectrum, this phenomenon is referred to as metamerism phenomenon.
The technical solution adopted by the present invention to solve the technical problems is: adjust yellow black four color ink of green product matches color ratio
Example generates a kind of metamerism with color ink, should show under visible light white with color ink, and show black under infrared light,
It is made of a width image in 2 D code two-dimension code anti-counterfeit information, the color lump in the color lump figure of the image in 2 D code is all divided into two kinds, and one
Kind is black color lump, and another kind is white color lump,
Image in 2 D code is printed on the white space on certificate, for the white color lump in image in 2 D code color lump figure,
Ask under visible light with all show white under infrared light, using ordinary white ink print, in image in 2 D code color lump figure
Black color lump require show white under visible light, show black under infrared light, using above-mentioned metamerism match color ink
Printing, the image in 2 D code being printed on the white space of certificate in this way show white under visible light, show under infrared light
Image in 2 D code is obtained by scanning correct two-dimensional barcode information, and the personation and abuse of certificate can be effectively prevented.
Detailed description of the invention
The following further describes the present invention with reference to the drawings.
Fig. 1 image in 2 D code.
The Local map of Fig. 2 image in 2 D code.
Specific embodiment
In fig. 1 and 2, the color matching ratio for adjusting yellow black four color ink of green product, generates a kind of metamerism with color ink,
White should be shown under visible light with color ink, and show black under infrared light, width two dimension is made of two-dimension code anti-counterfeit information
Code image 1, the color lump in the color lump figure of the image in 2 D code 1 is all divided into two kinds, and one is black color lump 3, another kind is white
Color lump 2,
Image in 2 D code 1 is printed on the white space of certificate, for the white color lump 2 in 1 color lump figure of image in 2 D code,
Ask under visible light with all show white under infrared light, using ordinary white ink print, in 1 color lump figure of image in 2 D code
Black color lump 3 require show white under visible light, show black under infrared light, using above-mentioned metamerism match color ink
Printing, is printed on the white space of certificate in this way, shows white under visible light, image in 2 D code 1 is shown under infrared light,
It is obtained by scanning the information of correct image in 2 D code 1, the personation and abuse of certificate can be effectively prevented.
Claims (3)
1. a kind of invisible two-dimensional codes anti-counterfeit method of credentials, it is characterized in that: the method for anti-counterfeit, is made of two-dimension code anti-counterfeit information first
Then image in 2 D code is printed on the blank area of certificate using metamerism with color ink, is being demonstrate,proved by one width image in 2 D code
The blank area of part generates a kind of invisible two-dimensional codes image, shows blank image in the blank area of certificate under visible light, infrared
Show image in 2 D code under light, be obtained by scanning correct two-dimensional barcode information, whether can identify certificate in this way
There are problems that palming off infringement.
2. invisible two-dimensional codes anti-counterfeit method of credentials according to claim 1, it is characterized in that: adjusting yellow black four color ink of green product
Color matching ratio generate a kind of with color ink, white should be shown under visible light with color ink, and show black under infrared light.
3. invisible two-dimensional codes anti-counterfeit method of credentials according to claim 1, it is characterized in that: in the color lump figure of image in 2 D code
Color lump be all divided into two kinds, one is black color lump, another kind is white color lump, sky image in 2 D code being printed on certificate
