Further illustrated, in a campus passing verification scenario, as shown in fig. 9, the first target two-dimensional code 902 is composed of a first identity character 904 and a first sequence value 906, where the first identity character 904 is "http:// wx.url.cn 002/2022092 052011111/09541", including a first character 904-1 indicating an identity home position, a second character 904-2 indicating identity version information, a third character 904-3 indicating identity verification time, and a fourth character 904-4 indicating identity identification details, where the first character 904-1 is "http:// wx.url.cn" indicating identity position information corresponding to the first target two-dimensional code 904, the second character 904-2 is "v002" indicating that the identity verification version corresponding to the first target two-dimensional code 904 is 002 version, the third character 904-3 is "20220921-052011" indicating that the identity verification time corresponding to the first target two-dimensional code 904 is 20 seconds in 21 days 05 for 2 years and the fourth character 904-4 is "20209 seconds," and the fourth character 904-4 is "v002" indicating that the identity information corresponding to the first target two-dimensional code 904 is 09541.

It should be noted that, the third character 904 may be, but is not limited to, used for indicating whether the first target two-dimensional code 902 is valid, for example, assuming that the valid time of the target two-dimensional code is 10s, when 20 minutes and 33 seconds are 21 days of 2022, 09 months, and 21 days, the first target two-dimensional code 902 is overdue and invalid, and the corresponding authentication information is invalid and does not have the right of campus passing. And verifying the identity information corresponding to the first target two-dimensional code once, wherein the verification comprises the steps of sequentially verifying whether the identity attribution position represented by the first character corresponds to the current campus position information, whether the identity version information represented by the second character corresponds to the current campus passage verification version information, whether the identity verification time represented by the third character accords with the identity information to be verified, whether the identity identification detail represented by the fourth character is the identity identification allowed to pass by the current campus or not, and the identity information corresponding to the first target two-dimensional code passes the sequential verification under the condition that the verification passes sequentially.

Further by way of example, assume that the verification conditions for the target two-dimensional code for the current campus traffic are: the campus location information is 'http:// wx.url.cn', the current campus passing verification version information is v002, the maximum effective time of identity information to be verified is 10s, namely, the cached two-dimensional code information is unavailable after 10s, and the identity mark of the current campus allowed passing is 00000-99999.

As shown in fig. 9, in the identity information corresponding to the first target two-dimensional code 902, the identity attribution position represented by the first character 904-1 is consistent with the current campus location information, the identity version information represented by the second character 904-2 is consistent with the current campus traffic verification version information, the identity verification time represented by the third character 904-3 is effective, and the identity identification detail represented by the fourth character 904-4 is the identity identification allowed to pass by the current campus, so that the identity information corresponding to the first target two-dimensional code 902 passes verification.

As shown in fig. 9, in the identity information corresponding to the second target two-dimensional code 908, the identity attribution position represented in the second identity character 910 is consistent with the current campus location information, but the identity version information represented in the second identity character 910 is inconsistent with the current campus passage verification version information, so that the identity information corresponding to the second target two-dimensional code 908 is not verified.

According to the embodiment provided by the application, under the condition that the first identity character is obtained, the first identity character is verified once, wherein the first identity character comprises at least one of the following: a first character for representing the home location of the identity, a second character for representing the version information of the identity, a third character for representing the authentication time, and a fourth character for representing the identity details.

It should be noted that, the three-time verification of the identity information corresponding to the second target two-dimensional code and the one-time verification of the identity information corresponding to the first target two-dimensional code may be, but are not limited to, the same manner, and the specific embodiment may refer to the specific embodiment of the one-time verification of the identity information corresponding to the first target two-dimensional code.

As an alternative, after determining that the identity information associated with the target terminal is correct, the method further includes:

S1, opening the passing authority of target equipment for a user of the target terminal, wherein the target equipment is equipment for performing code scanning verification and opening the passing authority after the code scanning verification is passed.

After confirming that the payment information associated with the target terminal is correct, the consumption payment amount is deducted for the corresponding user, and the user completes the corresponding consumption payment.

In the public transportation scene, the target terminal is a client of the bus taking information of the associated user, the target device is a code scanner for carrying out bus taking verification on the bus taking two-dimension code of the bus taking information of the associated user, and the bus taking two-dimension code of the bus taking information of the associated user is displayed on the target terminal. After confirming that the riding information associated with the target terminal is correct, the user is instructed to complete the trip registration. A step of

As an alternative scheme, as shown in fig. 10, the above two-dimensional code verification method is applied to a two-dimensional code verification system 1002, where the two-dimensional code verification system 1002 includes a two-dimensional code acquisition module 1004 and a two-dimensional code verification module 1006, the two-dimensional code acquisition module 1004 includes a two-dimensional code acquisition sub-module 1008 and a two-dimensional code binding sub-module 1010, and the two-dimensional code verification module 1006 includes a two-dimensional code verification sub-module 1012, a two-dimensional code analysis sub-module 1014 and a two-dimensional code verification sub-module 1016. Further illustrating, the specific contents of the above sub-modules are as follows when the target two-dimensional code verification system 1002 is applied to a campus passing right verification scenario through an applet target two-dimensional code:

first two-dimensional code acquisition sub-module 1008

The two-dimensional code acquisition submodule 1008 may be used for, but is not limited to, instructing the server to acquire the two-dimensional code bound with the user ID. After the user passes the identity authentication, opening an applet, and acquiring a two-dimensional code through a network interface, wherein the two-dimensional code is bound with the ID of the user, and the two-dimensional code comprises the following components: the two-dimensional code with version number v002 being v2 version is followed by the character string encrypted by the user id through encryption algorithm, such as: http:// wx.url.cn/v 002/xxxxxxxx.

It should be noted that the encrypted character string may be used, but not limited to, for indicating the identification details corresponding to the user, or may be used, but not limited to, for indicating the identification details corresponding to the user and the effective time of identity verification of the two-dimensional code.

Note that, the authentication valid time information may be, but not limited to, set in another character string formed by the two-dimensional code, which is not limited in this embodiment.

After one two-dimensional code is acquired, in order to relieve the pressure of the server, one two-dimensional code is acquired at regular intervals of 1 minute. The user can also click the two-dimensional code to refresh.

(Two) two-dimensional code binding sub-module 1010

The two-dimensional code binding sub-module 1010 may be used, but is not limited to, for concatenating strings onto two-dimensional codes. After the two-dimensional code is obtained, in order to realize quick flashing of the two-dimensional code, a character string with a certain check rule is generated through a certain algorithm, and then the character string is spliced to the back of the two-dimensional code. The following is a custom of various algorithms for generating "concatenation strings", and the following explanation of how to concatenate is explained using the manner of "incremental algorithm". For example, based on the incremental algorithm used, the user two-dimensional code obtained from the server is: http:// wx.url/v 002/xxxxxxxx, and if the character string generated by the first algorithm is 100, the two-dimensional code displayed at the terminal is spliced as follows: the character string generated by the next increment algorithm is 101, the two-dimensional code generated after splicing is http:// wx.url/v 002/xxxxxx-101, and the like, which is equivalent to the two-dimensional code displayed on the user equipment, and consists of a spliced character string generated by the algorithm and binding the two-dimensional code of the user id.

And on the time interval, refreshing the two-dimensional code on the applet once by generating a character string through an algorithm every 100ms and then splicing the character string to the two-dimensional code. The effect that the two-dimensional code always flashes is seen from the UI. Within one minute, the same original two-dimensional code obtained from the server is used, but a character string with a certain rule generated by an algorithm is spliced at the back, so that the character string becomes a new two-dimensional code. The algorithm rules are used in the subsequent two-dimensional code verification module 1006.

Further, as shown in fig. 11, the same character strings included in the character string area 1104 indicate the same original two-dimensional code 1102, and different character strings included in the character string area 1106 indicate different two-dimensional codes having different sequence values, respectively. For example, the string region 1108 indicates two different two-dimensional codes, and the strings within the string region 1104 corresponding to the different two-dimensional codes are the same, while the strings within the corresponding string region 1106 are different. The two different two-dimensional codes are used for identity verification by the code scanner 1110.

In the time interval, the two-dimensional code on the applet is refreshed once by generating a character string through an algorithm and then splicing the character string to the two-dimensional code every 100 ms. The two-dimension code is always in the flickering effect from the UI, and the same original two-dimension code obtained from the server is used within one minute, and the character string with a certain rule generated by the algorithm is spliced at the back, so that the original two-dimension code becomes a new two-dimension code. This algorithm rule is used in the subsequent two-dimensional code verification module 1006.

(III) two-dimensional code verification sub-module 1012

The two-dimensional code verification sub-module 1012 can be used for verifying whether the type corresponding to the two-dimensional code is correct, for example, if the two-dimensional code with the code data beginning of http:// wx.url.cn corresponding to the two-dimensional code correctly indicates the current campus code, the identity information corresponding to the two-dimensional code with the code data beginning of other codes cannot obtain the campus right.

The two-dimensional code verification sub-module 1012 may be used for verifying whether the two-dimensional code is complete, for example, if the code data starts with http:// wx.url.cn/V002 is a V2 version campus code, the integrity judgment code length is 126; the code data is http:// wx.url.cn/V003 is the campus code of V3 version, and the integrity judgment code length is 211.

It should be noted that, the versions of the two-dimensional codes are different, and the corresponding integrity judgment code lengths are different.

Two-dimensional code verification sub-module 1012 may be used to verify, but is not limited to, whether the first campus code of the cache is out of date. When campus code data are cached, time is also cached, when a second complete campus code is read, the time interval between the first code and the second code cannot be more than 450ms, the campus code is refreshed once at 200ms, the interval is 450ms, the two-dimensional code which is continuously read is ensured to be only one code to be missed, if two codes are continuously missed, the interval time exceeds 450ms, the cached first campus code is discarded, and the two-dimensional code is accumulated again.

(IV) two-dimensional code resolution sub-Module 1014

The two-dimensional code parsing sub-module 1014 may be used for parsing and checking two campus codes that are continuously read.

(Five) two-dimensional code verification sub-module 1016

The two-dimensional code verification sub-module 1016 may be used for, but is not limited to, determining whether the spliced data is incremental data or not according to the generation specification of the applet end. For example, if the splicing rule is an incremental algorithm, then the code scanner needs to check whether the spliced portion of the two-dimensional codes satisfies incremental management, for example, the spliced portion of the first two-dimensional code is 101, the spliced portion of the second two-dimensional code is 102, and the check result is that incremental management is satisfied.

The two-dimensional code verification sub-module 1016 may be used, but is not limited to, for data verification to verify whether the parsed user data is consistent. The two-dimension code consists of a two-dimension code (II) binding user id and a spliced character string generated according to an algorithm, wherein after the spliced character string is verified to meet a rule in the first step, the two-dimension code of the user is proved to be not in screen capturing, the second part is to analyze the two-dimension code binding the user id, the section (http:// wx.url.cn 002/xxxxxxxx) is calculated through an encryption algorithm, the step is to decode the id of the user through a secret key, acquire the detailed information identity of the user through the id, and judge whether the user is a valid user of the current campus.

The two-dimensional code verification sub-module 1016 may be used for, but is not limited to, wind-controlled verification: the time difference between the resolved code generation time and the code scanner time is less than 300 seconds, wherein the interval time validity background is controllable, and the code can be issued through configuration.
