Description

Attendance checking method and device, computer equipment and storage medium

Technical Field

The present application relates to the field of positioning technologies, and in particular, to an attendance checking method, an attendance checking apparatus, a computer device, and a storage medium.

Background

Mobile attendance checking, also known as lbs (location Based services) attendance checking, is an attendance checking system that obtains the current location of a mobile terminal using various types of positioning techniques and sends the location to a network service platform through the internet to determine the attendance of a group or an individual at a specific place and within a specific time.

In the conventional technology, the mobile attendance checking usually adopts a positioning technology, and has four types: (1) global Positioning System (Global Positioning System): when the satellite and the mobile terminal are used, the longitude and latitude of the mobile terminal are obtained by a triangulation method according to the communication delay between a plurality of satellites and the same terminal. The current mobile phone GPS positioning precision is generally 50 meters away. (2) WiFi positioning: and when the mobile terminal is connected to a certain WiFi access point, the position of the user can detect more accurate longitude and latitude by accessing a corresponding table in the database. The WiFi positioning accuracy is generally about 20-50 meters. (3) And (3) IP address positioning: when the mobile terminal accesses the internet, it is assigned an IP address, which is region-dependent. By using the existing mapping relationship between the IP address and the area, the position of the mobile object can be located to an area of a city size. (4) Triangulation method: triangulation is a method of measuring the distance of a target triangularly and geometrically by measuring the angle of the target point to a known end of a fixed reference line. Triangulation can obtain the latitude and longitude of the user when the mobile terminal is within the signal range of three mobile telephone base stations.

However, in the current mobile attendance method, the user position information is based on the GPS or mobile base station signal, and the user positioning signal is required to be accurate, so that the mobile attendance cannot be completed when the user positioning has a large error.

It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

The attendance checking method can be applied to the application environment shown in figure 1. Wherein the terminal 102 communicates with the server 104 via a network. The terminal 102 is configured to send login information to the server 104, the server 104 queries scheduling information corresponding to the login information after receiving the login information, the scheduling information at least includes attendance reference point coordinates, then the terminal 102 acquires current positioning information, and checks the current positioning information based on the attendance reference point coordinates, if the current positioning information cannot be checked successfully, the positioning information may have a problem, so that a current position of the terminal which has checked successfully can be acquired, and the current positioning information is corrected according to the current position; and sending the corrected current positioning information to a server for attendance checking. Therefore, when the verification of the current positioning information fails, the position of the terminal is corrected according to the current position of the terminal which has succeeded in checking the attendance, a new attendance position is obtained, additional WiFi equipment does not need to be introduced for auxiliary positioning, the cost of an enterprise is not increased, in addition, the position is corrected, the accuracy of the attendance is guaranteed, moreover, the verification of the current positioning information is placed on the terminal side, the pressure on the server side can be reduced, the attendance efficiency is improved, wherein the terminal 102 can be but not limited to various personal computers, notebook computers, smart phones, tablet computers and portable wearable equipment, and the server 104 can be realized by an independent server or a server cluster consisting of a plurality of servers.

In an embodiment, as shown in fig. 2, an attendance checking method is provided, which is described by taking the method as an example applied to the terminal in fig. 1, and includes the following steps:

s202: and sending login information to the server, and receiving scheduling information corresponding to the login information returned by the server, wherein the scheduling information at least comprises attendance reference point coordinates.

Specifically, the login information may include a user name and a password, the user name and the password are information for logging in the attendance software, and the user name may be a user account name. Preferably, the login information further includes device information, which is information for uniquely identifying the terminal.

The scheduling information is the scheduling of the user corresponding to the login information, and the scheduling information may be acquired by the server from a scheduling server, and the scheduling information at least includes the coordinate of the attendance reference point, and optionally, the attendance information further includes the information such as the maximum distance value allowed by the attendance reference point, the attendance time interval, and the like.

Specifically, after receiving the login information, the server acquires a user name corresponding to the login information, then queries corresponding scheduling information based on the user name, and sends the queried scheduling information to the terminal. In addition, optionally, before the server inquires the scheduling information, the server can also acquire the device information corresponding to the user name, if the device information transmitted by the acquired device information checking terminal is the same, the login is successful, and the corresponding scheduling information is continuously inquired, otherwise, the login is failed, namely, the server firstly checks the device information, and if the device information is not matched, the server prompts that the original device is required to be unbound to log in the new device, so that the problem of punching the card instead of checking the attendance among the users can be prevented by a mode of binding the user identity information (the user name and the password) and the device information.

In addition, optionally, for a user who successfully logs in for the first time, that is, a server does not inquire a corresponding user name, storing login information, that is, binding the user name and device information, and generating a random character string as a key corresponding to the device information for use in subsequent device card-punching and signature; and the user opens the software for the second time, the software automatically logs in, the server firstly verifies the equipment information, and if the equipment information is not matched, the server prompts that the new equipment can be logged in only if the original equipment needs to be unbundled.

It should be noted that, if the user identity authentication is passed, the server returns the user scheduling information for checking the local attendance of the user mobile device. The scheduling information comprises attendance reference point coordinates, an attendance reference point allowed maximum distance value, an attendance time interval and other information. Therefore, the shift information is verified on the mobile equipment local machine, so that the pressure of invalid attendance requests on the server can be reduced, and the processing capacity of the server is improved.

S204: and acquiring current positioning information.

Specifically, the longitude and latitude of the current position of the user are acquired through a GPS positioning technology.

S206: and checking the current positioning information according to the coordinates of the attendance reference point.

Specifically, the longitude and latitude of the position and the coordinate longitude and latitude of the attendance reference point are subjected to linear distance calculation, and if the longitude and latitude of the position and the coordinate longitude and latitude of the attendance reference point are smaller than the maximum distance value allowed for attendance, the local position passes verification.

Optionally, after checking the current positioning information according to the attendance reference point coordinates, the method further includes: and if the verification is successful, uploading the current positioning information to the server. That is to say, after the local verification of the user passes, the user clicks the attendance checking and card punching button to report the position information of the user. And the server records the data to the database when receiving the information, and waits for the subsequent second verification (the non-instant verification can improve the processing capacity of the server during the time period of punching the card by the user).

S208: and if the verification fails, acquiring the current position of the terminal with successful attendance checking, and correcting the current positioning information according to the current position.

And when the GPS positioning information of the user has a large error with the actual position, and the user cannot check and punch the card through checking, entering position information correction logic to correct the GPS position of the user to the actual position.

Specifically, the correction mode may be to acquire the current position of the terminal that succeeds in attendance, so that the current positioning information is corrected according to the current position, that is, the terminal of the user that succeeds in attendance is used as the fixed attendance machine. Optionally, in practice, the condition for acquiring the terminal with successful attendance may be set to be that the terminal is close to the terminal with successful attendance, for example, the current position of the terminal with successful attendance can be acquired only in a code scanning manner. Thus, the current positioning information is corrected through the current position.

S210: and sending the corrected current positioning information to a server for attendance checking.

Specifically, the user clicks an attendance card punching button and reports the user position information. And the server records the data to the database when receiving the information, and waits for the subsequent second verification (the non-instant verification can improve the processing capacity of the server during the time period of punching the card by the user).

According to the attendance checking method, when the current positioning information is failed to be checked, the position of the terminal is corrected according to the current position of the terminal which has successfully checked, a new attendance checking position is obtained, additional WiFi equipment does not need to be introduced for auxiliary positioning, cost cannot be increased for enterprises, in addition, the position is corrected, the attendance checking accuracy is guaranteed, the pressure of a server side can be reduced by placing the current positioning information to be checked on the terminal side, and therefore the attendance checking efficiency is improved.

In one embodiment, acquiring the current location of the terminal that has successfully checked in includes: scanning a graphic code generated by a terminal which has successfully checked in, wherein the graphic code is generated according to the position information of the terminal which has successfully checked in; and analyzing the graphic code to obtain the current position of the terminal with successful attendance checking.

Specifically, referring to fig. 3, fig. 3 is an environment diagram of a current location information correction manner in an embodiment, in which the purpose is to correct the GPS display location of user B to the actual location of user B, and then B sends a network request to complete the card punching through its own terminal, for example, a mobile device.

As shown in fig. 3, O is an attendance reference point, r is an attendance range radius, B is an actual position of the user B, and B is a GPS display position of the user B. A is the attendance position of the user A.

And br is greater than r due to the GPS positioning position error of the user B, and the card cannot be punched. And the user A normally positions and punches the card for normal attendance. At this moment, after attendance checking is successful, the mobile device of the A can be used as a fixed attendance machine, namely, the mobile device of the A generates a two-dimensional code according to the position information, the device information, the user information and the local time information of the A, the two-dimensional code is newly generated every 3 seconds (preventing user screen capture cheating), the mobile device of the B can correct the position of the B to the position of the A by scanning two continuous two-dimensional codes of the A, and then the B can finish attendance checking and card punching (Br < r after correction).

Namely, the A can punch the card normally, which shows that the position information and the equipment information of the A pass the server authentication, and the equipment of the A can be used as one of the punching attendance points in the attendance system; b can scan the two-dimensional code of A, which shows that the two codes are close to each other in actual distance, so that B can be also positioned at the actual position of A; the two-dimensional code of A changes once every 3 seconds, has prevented that user A from sending to the people far away from oneself through the network after the screen shot, and B need scan two consecutive two-dimensional codes that A generated, the possibility of attendance cheating.

In one embodiment, after sending the login information to the server, the method further includes: receiving key information returned by the server, wherein the key information is generated by the terminal logging in the server for the first time; sending the corrected current positioning information to a server for attendance checking, wherein the attendance checking method comprises the following steps: and encrypting the corrected current positioning information through the secret key, and sending the encrypted current positioning information to a server for attendance checking.

Specifically, in order to ensure the security of the current positioning information, when the terminal registers, the server allocates a unique secret key for the terminal, so that when the terminal needs to send the current positioning information to the server, the terminal can encrypt the current positioning information through the secret key, thereby ensuring the security of the current positioning information, and particularly under the condition of an offline state, the user information is transmitted by using a two-dimensional code technology and an encryption technology, so that offline attendance card printing under the condition of no network is realized.

In one embodiment, before sending the corrected current positioning information to the server for attendance checking and/or before uploading the current positioning information to the server, the method includes: acquiring a current network state; and when the current network state is an offline state, generating signature information according to the current positioning information, wherein the signature information is used for sending the current positioning information to the server after the terminal in the online state scans.

Specifically, when the mobile device of the user B has a poor signal or no signal, the mobile device cannot be positioned or cannot send position information to the server, information transmission can be performed offline, user information, device information and the like of the user B can be conveniently transmitted to the adjacent attendance device a, the attendance device of the user B is used for completing card punching, and the identity information of the user B does not need to be manually input into the device of the user B.

In practical application, the user A can punch a card normally, the position information and the equipment information of the user A are proved to pass the server authentication, and at the moment, the equipment of the user A can be used as one of the punching attendance points in the attendance system.

If the user B equipment has no network or cannot be positioned, B can open attendance software, the software reads the local equipment information, time information, random code information and signature information (the equipment information, the time information, the random code information and the secret are combined together and generate the signature information according to an SHA1 algorithm, wherein the secret is generated and issued by a server when the user binds the equipment at first and is matched with the equipment information), a two-dimensional code is generated, and the two-dimensional code is refreshed every 3 seconds.

And the user B scans the two-dimensional code generated by the attendance software for the equipment A.

Optionally, after the signature information is scanned by the terminal in the online state, the terminal in the online state performs time check, and after the time check passes, the current positioning information is sent to the server. That is to say, after the device A scans and identifies the two-dimensional code, the time information in the two-dimensional code is compared with the time of the device A, the time check is passed within 3 seconds of error, and then the device information and the time information in the two-dimensional code are sent to the server. And the server checks the time information again, and the time check is passed within 5 seconds of the time error of the server.

After the time check is passed, the server generates signature information by using the device information, the time information, the random code information and the secret corresponding to the device stored by the server together with SHA1, and compares the signature information with the uploaded signature information, if the signature information is consistent, the signature check is passed. If the request is not consistent, the request is forged, and the signature verification is not passed.

After the signature verification is passed, the server side receives the device information of the B uploaded by the A, obtains the user information corresponding to the device through the 1:1 binding relationship between the device and the user recorded by the server, records the user information as that the user B punches the card once, and records the user B attendance card successfully when the user B punches the card twice continuously.

The user A can punch a card normally, the position information and the equipment information of the user A are proved to pass the server authentication, and the equipment of the user A can be used as one of the punching attendance points in the attendance system. And the B equipment information is bound with the B user identity information when the previous user identity authentication is successful, namely the B equipment information can be regarded as the B user identity information. The two-dimensional code of B changes once every 3 seconds, and needs A to scan two-dimensional codes of B continuously and send information to the server for verification and pass, has prevented that user B sends the cheating possibility of a very far away A scanning and punching card through the network after the screen two-dimensional code is intercepted. The B two-dimensional code contains signature information unique to the B device, and the possibility that a user breaks away from the device to forge a card punching request is prevented.

In the above embodiment, when the signal of the mobile device of the user is not good or no signal exists, the mobile device cannot be positioned or cannot send the position information to the server, and offline information transmission can be performed to complete attendance checking and card punching.

In an embodiment, as shown in fig. 4, an attendance checking method is provided, which is described by taking the method as an example applied to the server in fig. 1, and includes the following steps:

s402: and receiving login information sent by the terminal, and inquiring scheduling information corresponding to the login information, wherein the scheduling information at least comprises attendance reference point coordinates.

Specifically, after receiving the login information, the server acquires a user name corresponding to the login information, then queries corresponding scheduling information based on the user name, and sends the queried scheduling information to the terminal. In addition, optionally, after receiving the login information sent by the terminal, the method further includes: extracting device information from the login information; and judging whether the equipment information is consistent with the equipment information stored in advance, and if not, sending login failure information to the terminal. Before the server inquires the scheduling information, the server can also acquire the equipment information corresponding to the user name, if the equipment information sent by the equipment information checking terminal is the same, login is successful, and corresponding scheduling information is continuously inquired, otherwise, login is failed, namely, the server firstly checks the equipment information, and if the equipment information is not matched, the server prompts that the original equipment is required to be unbound to log in new equipment, so that the problem of card punching instead of attendance checking between users can be prevented by a mode of binding the user identity information (the user name and the password) and the equipment information.

In addition, optionally, after receiving the login information sent by the terminal, the method further includes: judging whether a terminal corresponding to the login information logs in for the first time or not; when the terminal logs in for the first time, key information is generated and sent to the terminal, and the key information is used for encrypting the current positioning information when the terminal sends the current positioning information. That is, for a user who successfully logs in for the first time, that is, a server does not inquire a corresponding user name, the login information is stored, that is, the user name and the device information are bound, and a random character string is generated and used as a secret key corresponding to the device information for subsequent device card-punching signature; and the user opens the software for the second time, the software automatically logs in, the server firstly verifies the equipment information, and if the equipment information is not matched, the server prompts that the new equipment can be logged in only if the original equipment needs to be unbundled.

S404: and sending the scheduling information to the terminal, wherein the scheduling information is used for verifying the current positioning information according to the coordinates of the attendance reference point after the terminal acquires the current positioning information, acquiring the current position of the terminal which has successfully checked after the verification fails, and correcting the current positioning information according to the current position.

Specifically, the terminal obtains the longitude and latitude of the current position of the user through a GPS positioning technology. And performing linear distance calculation on the longitude and latitude of the position and the coordinate longitude and latitude of the attendance reference point, and if the longitude and latitude of the position and the coordinate longitude and latitude of the attendance reference point are smaller than the maximum distance value allowed for attendance, checking the local position to pass. Optionally, after checking the current positioning information according to the attendance reference point coordinates, the method further includes: and if the verification is successful, uploading the current positioning information to the server. That is to say, after the local verification of the user passes, the user clicks the attendance checking and card punching button to report the position information of the user. And the server records the data to the database when receiving the information, and waits for the subsequent second verification (the non-instant verification can improve the processing capacity of the server during the time period of punching the card by the user).

S406: and receiving the corrected current positioning information sent by the terminal, and finishing attendance checking according to the corrected current positioning information.

In one embodiment, the generation mode of the attendance reference point coordinates includes: acquiring current positioning information uploaded in a preset time period; and carrying out equalization processing on the position in the current positioning information to obtain the coordinate of the attendance reference point.

Specifically, after the attendance system operates for a period of time, the server records the coordinates of attendance check-in points of many users, and recalculates a new more reasonable attendance reference point by analyzing the distribution of the coordinate points which are successfully checked-in, thereby being beneficial to improving the user experience and improving the actual success rate of checking-in of the users.

The preset time period can be set by a user according to needs, namely, the periodical updating of the coordinates of the attendance reference point is realized.

The equalization processing may be to calculate an average value of the current positioning information in a preset time period, and use a position corresponding to the average value as a new attendance reference point coordinate.

Specifically, referring to fig. 5, fig. 5 is a scene diagram of coordinate updating of an attendance reference point in an embodiment, in which a point O is a current attendance reference point, and a point a, a point B, a point C, a point D, a point E, a point F, a point G, a point H, a point I, a point J, and the like are coordinate point sets for checking on the attendance of a user. The point O is the central point of A-J, namely the actual card punching positions of the user are all around the point O for punching, and the actual card punching positions are offset from the original reference point O. The origin O is the reference point, point K in fig. 5 cannot be punched because point K is outside the range of point O. After the attendance reference point is corrected to be a red o point, the point K is located in the range of the new reference point o, and the point K in the figure 5 can be used for successfully punching the card.

The o (x, y) point coordinate calculation method:

x = (Ax + Bx + ... + Jx) / N

y = (Ay + By + ... + Jy) / N

x is longitude, y is latitude, and N is the number of points participating in the calculation, i.e., the number of current positioning information in the preset time period.

In the embodiment, the position of the attendance reference coordinate point is corrected by using a data analysis technology, so that the attendance reference coordinate point is more reasonable.

In one embodiment, after completing attendance checking according to the corrected current positioning information, the method further includes: acquiring a risk early warning model, wherein the risk early warning model is generated according to preset attendance checking rules; inquiring attendance information corresponding to the current positioning information, and inputting the attendance information into a risk early warning model to judge whether the attendance information has risks; and when the attendance information has risks, outputting an attendance risk prompt.

Specifically, after receiving the current positioning information, the server may analyze the current positioning information, where the analysis dimensions include time to punch a card, place to punch a card, a mode to punch a card (punching a card by the device itself, punching a card after position correction, offline data transfer punching a card), and a device to punch a card, that is, the server needs to first obtain attendance information corresponding to the current positioning information, and input the attendance information to the risk early warning model together through the associated positioning information to determine whether the attendance information is at risk. Specifically, the attendance rules may include: in an actual attendance card punching scene, a certain user cannot punch cards at the same time of punching cards continuously for several days, the user cannot punch cards continuously for several days on the same longitude and latitude coordinates, position correction or offline card punching should not be frequently performed in a short period, the user should not continuously punch cards for several days, and a certain device completes self card punching and also completes offline card punching actions for assisting other devices for many times in several minutes every day (batch cheating actions may exist). Therefore, the card punching information of the user can be analyzed through the preset risk early warning model to identify whether attendance cheating behaviors exist or not, and early warning is carried out. The risk model thresholds include: the continuous 2-day card punching time is the same (accurate to the second)/the continuous 2-day card punching coordinate is the same in longitude and latitude/the position correction card punching mode within 5 days exceeds 3 times/the offline data transmission card punching mode within 5 days exceeds 3 times/the device punches the card per se within 2 days and assists other devices to punch the card offline for more than 3 times within 5 minutes. Wherein the specific values can be adjusted as desired. The suspected cheating attendance behavior can be analyzed and found through the risk early warning, and then manual examination and intervention can be carried out by personnel.

In the embodiment, the data analysis technology is used for automatically examining the user attendance data and carrying out early warning and reminding on cheating behaviors of the user attendance.

It should be understood that although the steps in the flowcharts of fig. 2 and 4 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise. Moreover, at least some of the steps in fig. 2 and 4 may include multiple steps or multiple stages, which are not necessarily performed at the same time, but may be performed at different times, which are not necessarily performed in sequence, but may be performed in turn or alternately with other steps or at least some of the other steps.

In one embodiment, as shown in fig. 6, there is provided an attendance checking apparatus applied to a terminal, including: a first sending module 100, a positioning module 200, a verification module 300, a correction module 400 and a second sending module 500, wherein:
