Embodiment 1

[0038] A two-dimensional code anti-counterfeiting method for metal parts, characterized in that:

[0039] Step 1, generate a product QR code from the product identification code;

[0040] Step 2, select a random point in the two-dimensional code, and store the random point information in the database;

[0041] Step 3: Mark the two-dimensional code of the product on the surface of the metal part, and make the marking depth of a random point in the two-dimensional code have a depth difference from the reference marking depth of other points in the two-dimensional code.

[0042] Step 4: Scan the product QR code on the metal part through the client 2 to obtain the product identification code, connect to the database, check whether the product identification code and the corresponding random point position match the information in the database, and finally obtain the authenticity information of the metal part.

[0043] The invention discloses an anti-counterfeiting method for two-...

Abstract

The invention belongs to the field of anti-counterfeiting labels, and in particular relates to a two-dimensional code anti-counterfeiting method for a metal part. The method is used for authenticity identification by randomly marking different depths on a metal part, and includes a first step of generating a product two-dimensional code from a product identification code; a second step of selecting a random point in the two-dimensional code, and storing the random point information in a database; a third step of marking the product two-dimensional code on the surface of the metal part, and enabling a depth difference between the marking depth of the random point in the two-dimensional code and the reference marking depth of the rest points of the two-dimensional code; and a fourth step ofobtaining the product identification code by scanning the product two-dimensional code on the metal part with a client, connecting to the database, inquiring whether the product identification code and the corresponding random position location match the information in the database, and finally obtaining authenticity information of the metal part. The invention discloses the two-dimensional code anti-counterfeiting method for the metal part, the two-dimensional code is allowed to have an anti-counterfeiting function and, combined with the characteristics of the metal part, a counterfeiter cannot perform batch copying.

Description

technical field [0001] The invention belongs to the field of anti-counterfeiting labels, and in particular relates to a two-dimensional code anti-counterfeiting method for metal parts which is used for authenticity identification by randomly marking different depths on the metal parts. Background technique [0002] The two-dimensional code uses a specific geometric figure to record data symbol information in a black and white pattern distributed on a plane according to a certain rule. In the code compilation, "0" and "1" (the white part is "0", the black part is "1"), which is essentially a two-dimensional matrix composed of "0" and "1". figure 1 It is a QR code with the content "12345678", figure 2 is the matrix corresponding to this QR code. [0003] With the improvement of network speed and the promotion and application of smart phones, more and more industrial products are printed with QR code information, and users can quickly query product information by scanning th...
