Embodiment Construction

[0046] In this embodiment, a method for generating a two-dimensional code is performed in the following steps:

[0047] Step 1, define variable i, initialize i=1;

[0048] Step 2. Generate traceability codes in batches;

[0049] Step 2.1, using formula (1) to obtain the interval length R of the traceability code l ;

[0050]

[0051] In formula (1), l represents the length of the traceability code; n represents the number of generated traceability codes, and R max Indicates the maximum value of the random function Rand();

[0052] Assuming that the length of the traceability code is l=9, the traceability code is generated from 000000000 to 99999999, and a maximum of 1000000000 traceability codes can be generated; assuming that the product needs to generate 100,000 traceability codes, that is, n=100000, then the formula (1 ) to calculate the interval length This example is running in the windows environment, taking the maximum value R of the random function Rand() max...

Abstract

The invention discloses a two-dimensional code generation method and an application thereof. The method is characterized by including the steps: 1 generating source tracing codes; 2 generating prefix codes; 3 generating Y-bit verification codes; 4 storing the source tracing codes, the prefix codes and the Y-bit verification codes into an anti-fake database, and generating an initial two-dimensional code by the aid of a bar code generator after the source tracing codes and the prefix codes are combined; embedding the Y-bit verification codes into the middle of the initial two-dimensional code to form a two-dimensional code. A lot of two-dimensional codes with high anti-fake performance and difficult simulation can be rapidly and stably generated, so that uniqueness of the two-dimensional code is effectively ensured, and the two-dimensional code is prevented from being copied or repeatedly used.

Description

technical field [0001] The invention relates to the technical field of two-dimensional code anti-counterfeiting, in particular to a method for generating a two-dimensional code and an application thereof. Background technique [0002] At present, anti-counterfeiting methods based on QR codes mostly adopt the method of "scanning + input": download and install the specified mobile client, "scan" the QR code through the mobile client to link to the corresponding website verification interface, and open the "Input" the verification code in the verification interface, and then the server completes the verification of the authenticity of the verification code, and returns the verification result information to the client to complete the verification of the product's authenticity. This anti-counterfeiting method has its limitations: [0003] 1. Verify the authenticity of the product through a verification code, with a single method and simple anti-counterfeiting means. [0004] 2...
