Embodiment Construction

[0011] Assuming that a certain type of product of a certain manufacturer is the first product to adopt this anti-counterfeiting code, then the category code of this product is 0001, this product is the first product of this type of product in 2013, and the annual output of this type of product is 8 digits , then its code is 1300000001. The secret level required by the manufacturer is one billionth, so its password is * * * * * * * *.

[0012] The overall code of the first product of this type of product in 2013 is:

[0013] "A" "B" "C"

[0014] 0001 1300000001 * * * * * * * *。

[0015] The overall code of the Nth product of this type of product in 2013 is:

[0016] 0001 13N * * * * * * * *. and so on.

Abstract

The invention discloses an anti-counterfeiting coding method which relates to a three-section composite code composed of a product category code, a product sequence code and a disorder random cipher, wherein the product sequence code comprises time information.

Description

technical field [0001] The invention is an anti-counterfeiting coding method. Background technique [0002] Currently known anti-counterfeiting methods are either complicated and inconvenient to use, difficult for ordinary consumers to identify, or have limited capacity and high rate of duplication. Contents of the invention [0003] The anti-counterfeiting coding method of the present invention adopts three sections of composite coding: A+B+C. [0004] A is the manufacturer and category code of the product. [0005] B is a product serial code containing time information (at least containing the year). [0006] C is an irregular random password, which needs to be covered. [0007] The number of digits of code A is determined by the number of manufacturers and product categories that adopt this encoding method, and the digits increase smoothly from less to more. [0008] The number of digits of the B code is determined by the annual output of the product, as long as it ...
