in the second step, basic bar code elements of the two-dimensional code or the one-dimensional bar code are associated with the content of the bar code, and the basic bar code elements of each bar code have a unique arrangement mode; the method comprises the steps that verification character strings generated after the content capable of being identified by the bar code per se is compiled through a certain rule or the content capable of being identified by the bar code per se is decomposed into continuous single characters, and the characters are correspondingly printed on each basic element of the bar code according to the definable rule and have a one-to-one corresponding relation;
in the third step, the magnifying glass is used for identifying the tiny characters attached to the basic elements of the bar code, the characters are sequentially formed into character strings, the character strings are compared with the clear codes of the bar code content or the verification character strings displayed on the link website, and if the character contents are consistent, the characters can be identified as true and effective; if the microcode is not identifiable, or the microcode does not have a complete one-to-one correspondence with the bar code elements in the physical position, or the content is inconsistent with the content of the verification character string, the label is not produced through a normal channel, and the label is considered as counterfeit.
Preferably, in the second step, the basic barcode element is a minimum point on the two-dimensional code or a minimum line on the one-dimensional barcode.
Preferably, in the third step, the user-defined arrangement mode of the miniature character strings is one of horizontal arrangement, vertical arrangement or oblique line arrangement.
Preferably, in the third step, the miniature character string can customize the cycle display mode and the cycle number.
Preferably, in the third step, the size ratio relationship between the miniature characters and the basic barcode elements can be customized.
Preferably, in the third step, the position relationship between the miniature character and the basic barcode element is self-defined.
Preferably, in the third step, the miniature character printing can select fonts with different sizes and types, and can be a negative character, a positive character, a framed character or a set pattern for replacement.
Compared with the prior art, the invention has the beneficial effects that: the invention is safe and reliable, the micro characters are printed on the minimum point on the two-dimensional code or the minimum line on the one-dimensional bar code, the anti-counterfeiting purpose is realized by self-defining the arrangement mode, the circulation mode and the display mode of the micro character strings and the physical corresponding positions of the micro characters on bar code elements, the micro characters attached to the bar code basic elements are identified through a magnifier to form character strings in sequence, and the character strings are compared with the bar code content explicit codes or the verification character strings displayed on a link website to identify and use the bar code; due to the uniqueness of the content and the shape of each bar code, the bar codes and the two-dimensional code printing content generated by software in the anti-counterfeiting mode have great workload of manual drawing of each bar code and each two-dimensional code if copying and copying are carried out in the later period, so that the anti-counterfeiting effect is greatly improved.
