Electronic grain anti-fake method

Abstract

The present invention relates to one kind of product anti-fake method by utilizing the texture characteristics, such as shape, color, etc. of material and making anti-fake marker with the material. The randomly formed figure, color and amount in the marker are used as the anti-fake information, recorded, converted into code and stored in the data base of computerized identification system while being printed in anti-fake marker. The consumer can check the figure and color in the label via comparison with the code to verify the truth of the commodity and may also check the codes in the marker via comparison with those in computer data base to verity the truth of the commodity through modern communication means.

Description

technical field [0001] The invention relates to an anti-counterfeiting technology, in particular to an anti-counterfeiting method in which anti-counterfeiting information features are set on a product, and consumers can also check the number of patterns or colors of a structure by themselves, and also query the plain code corresponding to the number of patterns or colors as anti-counterfeiting information . Background technique [0002] Anti-counterfeiting is to solve a problem that is not easy to forge and easy to identify. At present, there are several anti-counterfeiting methods commonly used: one is to use special printing technology to make anti-counterfeiting signs, such as laser anti-counterfeiting, hidden ink anti-counterfeiting, super energy anti-counterfeiting, mesh anti-counterfeiting, etc., and use special equipment to manufacture product packaging , its anti-counterfeiting feature is all the same, and the anti-counterfeiting feature is manufactured, which is ea...

Problems solved by technology

Print the password on the logo and cover it up, and store the number in a computer database that can be queried by consumers. When purchasing, consumers tear off the number on the logo and enter it for comparison and identification by telephone or the Internet. The same is true, and the difference is false. However, in practice, it is found that: due to its extremely low query rate, about 2 / 1000 to 5 / 1000, (1) both a large number of numbers can be recycled, and one code can be used. Multi-printing, batch forgery, (2) A large number of numbers can be copied, (3) Special instrument perspective code, (4) Malicious destruction of the enumeration method program, (5) The covering layer of the marker cannot be scratched due to too long time

One is texture anti-counterfeiting: mainly to change the anti-counterfeiting feature of electronic code anti-counterfeiting printing - digital password into the inherent structural texture of non-man-made identification materials, that is, after scanning the graphics on paper with fibers (such as the new version of RMB) that people intentionally make Store it in a queryable database, and then divide the anti-counterfeiting mark into 12 small squares. Consumers can check whether there is fiber or check their graphics in these 12 small squares by phone. However, it is found through practice that (1) the query procedure is very complicated , consumers have no intention of querying, and will not query

(2) Since the answer is yes and no, the answer is too simple and rough, with only 12 squares, and it is judged by simple "yes or no" or checking graphics

(3) Due to the problems mentioned in (1) and (2), the inquiry rate is extremely low, about two thousand molecules, and a large number of markers have not been inquired, which means that no anti-counterfeiting is used

(4) Due to the low query rate, complex queries and simple answers, it is easy for counterfeiters to reproduce in batches by recycling old labels and reprinting them

(5) Due to the low query rate, the manufacturer does not think it is necessary to use anti-counterfeiting
