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-...
Embodiment 2
[0045] A two-dimensional code anti-counterfeiting method for metal parts, characterized in that:
[0046] Step 1, generate a product QR code from the product identification code;
[0047] Step 2, select a random point in the two-dimensional code, and store the random point information in the database;
[0048] 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.
[0049] 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.
[0050] In the second step, while the two-dimensional code is obtained...
Embodiment 3
[0061] A two-dimensional code anti-counterfeiting system for metal parts, including a two-dimensional code generation module, a random point generation module, a metal coding machine 1, a scanning module, an anti-counterfeiting query module, a client 2 and a data server, the two-dimensional code Generation module, random point generation module and anti-counterfeit query module are connected with database server 3 signals respectively, and described two-dimensional code generation module and random point generation module are connected with metal coding machine 1 signal, and described scanning module and anti-counterfeit query module are connected with client The terminal 2 signal is connected.
[0062] The two-dimensional code generation module utilizes the product logo code to generate two-dimensional code graphics; the random point generation module is used to generate a group of random points in the black area of the two-dimensional code; the scanning module calls the cam...
