Problems solved by technology

Traditional two-dimensional codes such as QR codes need a clean area for placement, and QR codes, etc., as an open technology, can be forged at will, and it is easy to connect to an unsafe website by using the scanner that comes with the mobile phone. Not only will it lose the anti-counterfeiting function, it will also bring unexpected losses

Embodiment Construction

[0040] Such as figure 1 As shown, the anti-counterfeiting method based on the two-dimensional code of the present invention comprises the following steps:

[0041] Step 11: Correspond each product to an independent number S, and generate an index I for the independent number;

[0042] Step 12: Encrypt the index I with a private key to obtain an encryption number E, and the encryption number E corresponds to the index I one by one;

[0043] Step 13: Encoding the encryption number E and generating a two-dimensional code;

[0044] Step 14: The two-dimensional code and the logo icon are fused to form an anti-counterfeiting map, the two-dimensional code is placed on the upper layer, the logo icon is placed on the lower layer, and the overlapping area between the black module of the two-dimensional code and the logo icon shows the Described black module, described logo icon is shown in the overlapping area of ​​described two-dimensional code white module and logo icon;

[0045] S...

Abstract

The invention provides an anti-counterfeiting method based on a two-dimension code. Double effects of anti-counterfeiting are realized through the encryption of a public key and a private key and the integration and image acquisition of a two-dimension code and a logo icon. The combination of an anti-counterfeiting position and the logo icon has an obvious feature which can be identified at a glance. A counterfeiter bypassing the pattern is identified at a glance. Tampering and batch copying of a code content of the counterfeiter can be prevented.

Description

technical field [0001] The invention relates to anti-counterfeiting technology, in particular to an anti-counterfeiting method based on a two-dimensional code. Background technique [0002] The market has a wide demand for anti-counterfeiting of goods. Although the anti-counterfeiting effect at the physical level is good, the cost is relatively high. With the popularization of two-dimensional code reading equipment, using two-dimensional codes for anti-counterfeiting has its special advantages. Not only is the cost low, but also the product can be traced. Using the mobile network, it can also be connected to the database to obtain more product information. Traditional two-dimensional codes such as QR codes need a clean area for placement, and QR codes, etc., as an open technology, can be forged at will, and it is easy to connect to an unsafe website by using the scanner that comes with the mobile phone. Not only lose the anti-counterfeiting function but also bring unexpecte...
