Method and device for identifying anti-counterfeiting mark composed of two-dimensional code and raster graphic

Abstract

The invention provides a method capable of identifying a two-dimensional code and a raster graphic at the same time. The method includes the following steps that the two-dimensional code is scanned, a two-dimensional code image is analyzed, a raster graphic ID after the analysis is extracted; the raster graphic is scanned, a raster graphic image is analyzed, and therefore a raster graphic ID after the analysis is extracted; the two raster graphic IDs are compared, and therefore whether the two raster graphic IDs are matched or not can be judged; according to a matched result, content information corresponding to the two raster graphic IDs at the same time is called in a database; the content information is broadcasted. A device adopting the method comprises a shell, a trigger, a mainboard provided with a central processing chip, a two-dimensional code scanning part, a raster graphic scanning part, a comparison module, a calling module and a feedback module. According to the method and device for identifying the anti-counterfeiting mark composed of the two-dimensional code and the raster graphic, the anti-counterfeiting mark implanted into the surface of an article and composed of the two-dimensional code and the raster graphic can be scanned at the same time, after the two raster graphic IDs are compared, relevant content is fed back, and the defect that the anti-counterfeiting mark cannot be identified at present is overcome.

Description

technical field [0001] The invention relates to a recognition method, in particular to a method and device for recognizing an anti-counterfeiting mark composed of a two-dimensional code and a dot matrix pattern. Background technique [0002] Two-dimensional codes have been gradually introduced into the field of anti-counterfeiting technology because of their advantages such as large encoding information capacity, high decoding reliability, and easy production. By distinguishing different styles of two-dimensional codes, the authenticity of the item can be known. However, since the two-dimensional code can be easily copied or copied, the authenticity of the item can still be known when the copied or copied two-dimensional code is identified. Therefore, the information stored in the two-dimensional code is not safe. In addition, because the coding rules of the two-dimensional code are relatively simple, it is also very easy to be cracked. Once the coding rules of the QR code ...

However, since the two-dimensional code can be easily copied or copied, when the copied or copied two-dimensional code is identified, the authenticity of the item can still be known. Therefore, the information stored in the two-dimensional code is not safe.

In addition, because the coding rules of the two-dimensional code are relatively simple, it is also very easy to be cracked.

Once the coding rules of the QR code printed on the product are deciphered by others, it will not be able to achieve its effective effect, and it will be difficult to effectively crack down on counterfeit and shoddy goods

[0003] In order to solve the problem of poor anti-counterfeiting effect of the above-mentioned two-dimensional code, a new idea has emerged, which combines the two-dimensional code and dot matrix graphics to form a new type of anti-counterfeiting mark

Yet for this kind of anti-counterfeiting label, there is no method for identifying it at present
