Further, in order to improve readability and effectiveness of generating the two-dimensional code and avoid misidentification caused by local damage, the random number is generated on the redundant bit of the two-dimensional code.
Referring to fig. 2, a two-dimensional code recognition method is applied to an article attached with a two-dimensional code, where the two-dimensional code is generated by using the two-dimensional code generation method, and the recognition method includes:
s201, the scanning terminal identifies an anti-counterfeiting code in the two-dimensional code, and the anti-counterfeiting code is used as a first anti-counterfeiting code and is sent to a server;
specifically, the scanning terminal may adopt an intelligent terminal with a scanning function, after the two-dimensional code is scanned, the anti-counterfeiting code in the scanning information is acquired and sent to the server through the network, and the server may adopt a cloud server.

S203, according to the prompt of the verification page, the scanning terminal obtains the image information of the attached two-dimensional code and uploads the image information to the server;
specifically, the scanning terminal takes a picture of the two-dimensional code attached to the article and uploads the two-dimensional code, when the two-dimensional code is taken a picture, multi-angle shooting can be performed, and one picture or a plurality of pictures are uploaded, so that the method is not limited.
S204, the server processes the image information to obtain a random number and an anti-counterfeiting code on a redundant bit of the two-dimensional code in the image information, and takes the anti-counterfeiting code of the two-dimensional code in the image information as a second anti-counterfeiting code;
specifically, after image information of a verification page is obtained, a random number and an anti-counterfeiting code on a redundant bit of a two-dimensional code in the image information are obtained for verification, if the encrypted random number is inconsistent with the random number in a database, a 'the label is a fake label' is directly prompted, if the encrypted random number is consistent with the random number, the label is compared with an original picture collected when the two-dimensional code is attached to an article stored in a server, and due to the fact that the two-dimensional code is provided with a round hole, the two-dimensional code is torn off when being attached, and the round hole cannot be copied due to the; by the method, the situation that the real label is simulated by photographing and copying can be avoided.
S205, the server judges whether the second anti-counterfeiting code is stored in a database, if the second anti-counterfeiting code exists in the database, the server encrypts the random number according to preset key information to obtain a target random number, and if the second anti-counterfeiting code does not exist in the database, the server sends first prompt information to the scanning terminal;
s206, when the server judges whether the target random number is the same as the two-dimensional code in the generated image information, the random numbers stored in the database are different, if so, third prompt information is sent to the scanning terminal, and if so, second prompt information is sent to the scanning terminal.
Specifically, when the server does not exist or cannot acquire the anti-counterfeiting code in the identification process, the server directly sends first prompt information: and similar alarm information such as 'the code does not exist, please note' and the like is sent to the scanning terminal, when the acquired anti-counterfeiting code exists, the random number is acquired again, encryption processing is carried out, the encrypted target random number is obtained and compared with the random number stored in the database, and different prompt information is sent to the scanning terminal according to different comparison results.
Further, in order to enrich the diversity of the prompt information, the first prompt information, the second prompt information and the third prompt information are one or more of character information, picture information, video information and audio information, the first prompt information can adopt similar information such as ' the code does not exist and please note ', the second prompt information can adopt similar information such as ' the code exists, the label is a true label and is a genuine product ', and the third prompt information can adopt similar information such as ' the code exists, the label is a false label and please note
In specific applications, for example: for example, when a two-dimensional code (www.zy.com/qr/2345656777555) is generated, the generated random number is ABC, according to a key RTC, the generated random number is DCE, so that data reserved in the database is DCE, and the key is set when a client generates the code.
We identify the two-dimensional code by the program:
if the anti-counterfeiting code 2345656777555 is not in our database, the description is false;
if the data hidden on the anti-counterfeiting code does not have a string of characters preset by us, the anti-counterfeiting code is false;
if the data hidden on the anti-counterfeiting code is DFD, the random number is found to be ABD instead of DCE through encryption of a preset key, which indicates that the data is false;
if the data hidden on the anti-counterfeiting code is ABC, the fact that the random number is DCE is found through encryption of a preset secret key.
According to the invention, when the two-dimensional code is generated, the safety and the effectiveness of the generated two-dimensional code are improved by performing the key verification, the generation of the random number and the anti-counterfeiting code and arranging the round holes on each side of the two-dimensional code, and the authenticity can be conveniently identified in the identification process; meanwhile, through a specific identification method and a verification step, the authenticity judgment in the two-dimensional code identification process is improved, and the probability of counterfeiting the two-dimensional code is reduced.
