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 character matrix, different colours are assigned to number in each lattice according to obtained color sequence, are obtained
To colorful number matrix.Finally printed using pattern in 2 D code and colorful number matrix number of the two dimensional code spray code spraying apparatus to generation
Brush is sprayed the pattern in 2 D code of black by black code spraying head, is sprayed by colored code spraying head in the pattern in 2 D code side
Colorful number matrix.
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 character matrix, generate colorful number matrix；
Finally, by pattern in 2 D code and colorful number matrix and the server-side pattern in 2 D code and colorful number matrix that show on product
It compares, if the two mismatches, which is imitated imitative code.
The present invention passes through the colorful number matrix in pattern in 2 D code side printing nine grids form, nine grids size and two
It ties up code pattern magnitude to be adapted, number is printed using different colors in every lattice, obtains colorful number matrix, wherein color sequence
It is to be calculated by color sequence algorithm, after barcode scanning equipment barcode scanning, server-side presses same algorithm, should show completely the same
Two dimensional code, it is completely the same with the colorful number matrix of the pattern in 2 D code and one side swept, if the two mismatch, swept
Two dimensional code is imitated imitative code.Therefore, by a known two dimensional code, the pattern and colour of another two dimensional code can not be derived
The problem of character matrix solves two dimensional code by the imitated of batch, can not differentiate the true and false.
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
