8, the value for calculating key1%20, obtains key1=5；
9, the value for calculating key2%24, obtains key2=22；
It then, is row number by line number, key2 of key1, the 5th row the 22nd of queries dictionary table column obtain corresponding color sequence,
By color sequence in conjunction with corresponding two dimensional code sequence number, different colours are assigned to each group number according to obtained color sequence,
Obtain colorful number sequence.Finally carried out using pattern in 2 D code and colorful number sequence number of the two dimensional code spray code spraying apparatus to generation
Printing is sprayed the pattern in 2 D code of black by black code spraying head, is sprayed below the pattern in 2 D code by colored code spraying head
Apply colorful number sequence.
When anti-fake, using the pattern in 2 D code on barcode scanning equipment scanning product, two-dimensional code data therein, server-side are obtained
Pattern in 2 D code is generated according to the two-dimensional code data of acquisition；Meanwhile server-side uses color sequence algorithm to two dimensional code sequence number
It is calculated, obtains corresponding color sequence, by color sequence in conjunction with corresponding two dimensional code sequence number, generate colorful number sequence
Column；Finally, by pattern in 2 D code and the pattern in 2 D code that shows of colorful number sequence and server-side and colorful number on product
Sequence compares, if the two mismatches, which is imitated imitative code.
The present invention is divided into several groups by the printed color two dimensional code sequence number below pattern in 2 D code, two dimensional code sequence number
Number, every group is printed using different colors, obtains colorful number sequence, wherein color sequence is by color sequence algorithm meter
Obtain, after barcode scanning equipment barcode scanning, server-side press same algorithm, should show completely the same two dimensional code, with swept two
It is completely the same to tie up code, the color sequence of lower section, if the two mismatches, swept two dimensional code is imitated imitative code.Therefore, by one
Known two dimensional code can not derive the pattern and colorful number sequence of another two dimensional code, solve two dimensional code by batch
The problem of copying, the true and false can not be differentiated.
Above content is only to structure of the invention example and explanation, affiliated those skilled in the art couple
Described specific embodiment does various modifications or additions or is substituted in a similar manner, without departing from invention
Structure or beyond the scope defined by this claim, is within the scope of protection of the invention.
