[0002] At present, when using a wireless router device (wifi device) to record attendance for employees, students and other users, the user needs to connect to the wifi device and log in to the corresponding attendance software. Then the user performs identity authentication on the attendance software to complete the attendance record. The user needs to connect to the wifi device and log in to the attendance software, and this process takes too much time. In addition, the administrator needs to maintain the wifi device and attendance software, which also requires more resources. Furthermore, due to the large number of wifi devices, when the user performs attendance verification, if he cannot determine the wifi device he needs to connect to or connects to the wrong wifi device, he cannot complete the attendance verification, resulting in low attendance verification efficiency.

[0112] The following will be combined with the drawings in the embodiments of this specification to clearly and completely describe the technical solutions in the embodiments of this specification. Obviously, the described embodiments are only part of the embodiments of this specification, not all of the embodiments. Based on the embodiments in this specification, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this specification.

[0113] It should be noted that the terms "first", "second", etc. in the description and claims of this specification and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of this specification described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, device, product or equipment that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or equipment.

[0114] It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0115] In the technical solutions of this specification, the collection, storage, use, processing, transmission, provision, disclosure and application of user personal information involved are in compliance with the relevant laws and regulations, necessary confidentiality measures are taken, and do not violate public order and good morals.

[0116] Figure 1The diagram of the implementation system of an attendance method in an embodiment of the specification is shown, which may include: a hotspot terminal 101 and a server 102, wherein the hotspot terminal 101 and the server 102 communicate with each other through a network, and the network may include a local area network (LAN), a wide area network (WAN), the Internet or a combination thereof, and is connected to a website, a user device (such as a computing device) and a back-end system. A user may connect to or disconnect from the hotspot terminal 101 through an electronic device, and the hotspot terminal 101 determines the user ID of the electronic device, and the determined connection time and disconnection time. The hotspot terminal 101 sends the connection time and disconnection time to the server 102 as the start time and the end time, respectively. The server 102 may perform attendance verification for the user ID, the start time and the end time obtained through the hotspot terminal 101. When the user ID, the start time and the end time are all verified, the attendance success information is associated with the user ID. In the case that one of the user identification, start time and end time fails to pass the verification, the undetermined information is associated with the user identification, and a cancellation request is sent to the user's electronic device or other electronic devices associated with the electronic device. Further, a modification request is received from the user's electronic device or other electronic devices associated with the electronic device, and the modification request is verified. When it is determined that the modification request passes the verification, the modification request is determined to be a modification instruction, and the undetermined information is updated to attendance success information. Optionally, the server 102 can be a node of a cloud computing system (not shown in the figure), or each server 102 can be a separate cloud computing system, including multiple computers interconnected by a network and working as a distributed processing system.

[0117] In an optional embodiment, the hotspot terminal 101 may include any device that can connect an electronic device to a wireless local area network, and the electronic device is not limited to a smart phone, a collection device, a desktop computer, a tablet computer, a laptop computer, a smart speaker, a digital assistant, an augmented reality (AR) / virtual reality (VR) device, a smart wearable device, and other types of electronic devices. Optionally, the operating system running on the electronic device may include but is not limited to Android, IOS, Linux, Windows, and the like.

[0118] In addition, it should be noted that Figure 1 What is shown is only an application environment provided by this specification. In actual application, multiple hotspot terminals 101 may also be included, and this specification does not impose any limitation.

[0119] Figure 2The flowchart of an attendance method in an embodiment of this specification is shown. The attendance verification process is described in this figure, but it may include more or fewer operation steps based on conventional or non-creative labor. The order of steps listed in the embodiment is only one way of executing the steps among many orders, and does not represent the only order of execution. When the actual system or device product is executed, it can be executed in the order of the method shown in the embodiment or the accompanying drawings or in parallel. Specifically, Figure 2 As shown, the method may include:

[0120] S210, matching the user identifier with each preset user identifier in the preset user identifier set according to the received attendance request;

[0121] S220, when it is determined that the user identifier matches the target user identifier in the preset user identifier set, obtaining preset time period information;

[0122] S230, matching the first time period information with the preset time period information;

[0123] S240: When it is determined that the first time period information matches the preset time period information, the attendance success information is associated with the user identifier.

[0124] By receiving the attendance request sent by the wifi device, the user identification and the first time period information included in the attendance request are verified respectively. When both the user identification and the first time period information are verified, the attendance success information is associated with the user identification to complete the attendance verification. This improves the efficiency of attendance verification based on the wifi device and reduces the waste of resources in the verification process.

[0125] According to an embodiment of the present specification, the attendance request may be, for example, an instruction to request cancellation of a class. The attendance request is sent by a first device, which includes a wireless router device (wifi device). Cancellation of a class indicates that the target student has completed the study of the target course. For example, there is an English class in classroom 301 from 8:00 to 9:00, and student Zhang has signed up for the English class, and student Zhang has taken the English class in classroom 301 from 8:00 to 9:00, which means that student Zhang has completed the study of the target course (English class). The English class in classroom 301 from 8:00 to 9:00 may be cancelled for student Zhang. The user identifier may be, for example, address information of an electronic device, and the first time period information may be, for example, a successful connection time and a disconnection time associated with the address information of the electronic device.

[0126] Before the student starts the course to be taken, he / she enters the target associated classroom corresponding to the course to be taken, and uses an electronic device to connect to the wifi device of the target associated classroom, and the wifi device records the address information of the electronic device and the time of successful connection. After the course to be taken ends, the student uses the electronic device to disconnect the wifi device of the target associated classroom, and the wifi device records the address information of the electronic device and the time of disconnection. It should be noted that the wifi device records the address information and the time of successful connection for each electronic device connected to the wifi device when the connection is successful. Similarly, the wifi device records the address information and the time of disconnection for each electronic device disconnected from the wifi device when the connection is disconnected.

[0127] After the course is over, the wifi device sends the recorded address information of multiple electronic devices, the connection success time associated with each electronic device, and the disconnection time associated with each electronic device to the server.

[0128] The preset user identifiers of the students who attend the target course are summarized in advance to obtain a preset user identifier set, and the preset user identifier set is associated with the wifi device identifier of the target associated classroom corresponding to the target course.

[0129] In addition, the time period of the target course is associated with the preset user identification set as the preset time period information. For example, from 8:00 to 9:00, there is an English class in classroom 301, and the students taking the English class are student Zhang, student Li, and student Wang. Then the preset user identification set includes (student Zhang, student Li, and student Wang), and the preset user identification set is associated with the wifi device identification of the wifi device in classroom 301, and the preset user identification set is associated with the preset time period information of 8:00-9:00.

[0130] When receiving multiple user identifications sent by the wifi device, each user identification and the first time period information corresponding to the user identification are verified respectively. According to the wifi device identification, a set of preset user identifications to be selected corresponding to each course time period is determined, and from the multiple sets of preset user identifications to be selected, a set of preset user identifications to be selected corresponding to the course time period matching the current course time period is determined as the preset user identification set.

[0131] Taking a user ID and the first moment information corresponding to the user ID as an example to explain attendance verification, the user ID is matched with each preset user ID in the preset user ID set corresponding to the current moment to determine whether there is a preset user ID that is consistent with the user ID. When it is determined that there is a preset user ID that is consistent with the user ID, the preset user ID is used as the target user ID, and the target user ID is matched with the user ID.

[0132] When it is determined that there is a target user identifier that matches the user identifier, the preset time period information associated with the target preset user identifier set is obtained.

[0133] According to the matching of the first time period information and the preset time period information, the intersection duration of the first time period information and the preset time period information is determined. When it is determined that the intersection duration is greater than the preset duration threshold, it is determined that the first time period information matches the preset time period information, and the user ID is cancelled. The cancellation of the user ID may be, for example, associating the cancellation information with the user ID. The preset duration threshold may be, for example, 98 percent of the preset duration data included in the preset time period information.

[0134] For example, the first time period information is 8:01-9:03, and the preset time period information is 8:00-9:00, then the intersection time period is 8:01-9:00, the intersection duration is 59 minutes, the duration information of the preset time period information is 60 minutes, and the preset duration threshold is 58.8 minutes. If the intersection duration is greater than the preset duration threshold, it is determined that the first time period information matches the preset time period information, and the user identifier corresponding to the first time period information is cancelled.

[0135] According to another embodiment of the present specification, a method for determining a preset user identification set includes: determining, in a time period library, a plurality of course time periods corresponding to the current moment; determining, from the classroom location information corresponding to each course time period, target-associated classroom location information associated with the first device identifier; and using a plurality of preset address information corresponding to the target-associated classroom location information as a plurality of preset user identifiers to obtain a preset user identification set.

[0136] The time period library includes multiple preset course time periods and preset classroom location information corresponding to each preset course time period. The preset classrooms associated with each preset classroom location information are equipped with a wifi device, and the preset classroom location information is associated with the wifi device identifier. The preset address information includes the address information of the electronic device entered by the student when registering for the course. For each target course set in the preset classroom during each preset time period, the preset address information of the students who register for the target course is pre-associated with the preset classroom location information.

[0137] When the user identification and the first time period information sent by the wifi device configured in the target associated classroom are received, the device identification associated with the wifi device is used as the first device identification.

[0138] Determine whether the current moment is included in multiple preset course time periods, use the preset course time period including the current moment as the course time period, and use the preset classroom location information corresponding to each of the course time periods as the classroom location information. Obtain the wifi device identifier associated with each classroom location information. From the multiple wifi device identifiers, determine the wifi device identifier that is consistent with the first device identifier, and determine the classroom location information associated with the wifi device identifier as the target associated classroom location information associated with the first device identifier. After determining the target associated classroom location information, each of the multiple preset address information associated with the target associated classroom location information is used as a user identifier, and the multiple user identifiers are aggregated to obtain a preset user identifier set.

[0139] According to another embodiment of the present specification, the first time period information includes a start time and an end time, the preset time period information includes preset duration data, and matching the first time period information with the preset time period information includes: determining the duration data based on the start time and the end time; comparing the duration data with the preset duration data; and determining that the first time period information matches the preset time period information when it is determined that the duration data is greater than or equal to the preset duration data.

[0140] The preset duration data is the class duration of the target course. For example, there is an English class in classroom 301 from 8:00 to 9:00, and the preset duration data is 60 minutes.

[0141] When the first time period information includes a start time and an end time, the end time is subtracted from the start time to obtain the duration data. The duration data is compared with the preset duration data. If the duration data is greater than or equal to the preset duration data, the user identifier corresponding to the first time period information is cancelled.

[0142] When the first time period information includes, for example, multiple start times and multiple end times, each start time and each end time are sorted by time, and starting from the first start time, the sub-time lengths of adjacent start times and end times are determined to obtain multiple sub-time lengths. The sum of the multiple sub-time lengths is calculated, and when it is determined that the sum of the multiple sub-time lengths is greater than or equal to 98 percent of the preset time length data, the interval time length of the adjacent sub-time lengths is determined. When it is determined that the interval time lengths are all less than or equal to the interval time length threshold, it is determined that the first time period information matches the preset time period information.

[0143] Figure 3Shown is a schematic diagram of an attendance method according to an embodiment of this specification.

[0144] According to another embodiment of the present specification, the first time period information includes a start time and an end time, the preset time period information includes a preset start time set and a preset end time set, and matching the first time period information with the preset time period information includes: determining whether there is a target preset start time matching the start time in the preset start time set; if it is determined that the target preset start time exists, determining whether there is a target preset end time matching the end time in the preset end time set; if it is determined that the target preset end time exists, determining duration data based on the first time period information; determining the duration between the latest preset start time in the preset start time set and the earliest preset end time in the preset end time set as the preset duration data; and if it is determined that the duration data is greater than or equal to the preset duration data, determining that the first time period information matches the preset time period information.

[0145] The preset start time set includes the time information of the first preset time before the target course starts. The preset end time set includes the time information of the second preset time after the target course ends. For example, the first preset time includes 30 minutes before the target course starts, and the second preset time includes 30 minutes after the target course ends. When the start time and the end time are 8:00 and 9:00 respectively, the preset start time set includes all times between 7:30-8:00, and the preset end time set includes all times between 9:00-9:30.

[0146] When the first time period information includes, for example, a start time and an end time, determine whether there is a target preset start time that is consistent with the start time in the preset start time set. If it is determined that it exists, determine whether there is a target end time that is consistent with the end time in the preset end time set. If it is determined that it exists, subtract the start time from the end time to determine the duration data. Determine the latest time in the preset start time set, determine the earliest time in the preset end time set, and subtract the latest time from the earliest time to obtain the preset duration data. Compare the duration data with the preset duration data. When it is determined that the duration data is greater than or equal to the preset duration data, determine that the first time period information matches the preset time period information, and cancel the course for the user identifier corresponding to the first time period information.

[0147] like Figure 3As shown, the entire teaching area is taken as a preset area, and the teaching area includes six classrooms. For the preset area 300, it includes a first classroom 301, a second classroom 302, a third classroom 303, a fourth classroom 304, a fifth classroom 305, and a sixth classroom 306. For each classroom, a corresponding wifi device is equipped, and device 1, device 2, device 3, device 4, device 5, and device 6 are respectively equipped in the first classroom 301, the second classroom 302, the third classroom 303, the fourth classroom 304, the fifth classroom 305, and the sixth classroom 306.

[0148] The classroom location information associated with the first classroom 301 is used as the target-associated classroom location information associated with the device identifier associated with device one. Similarly, the classroom location information associated with the second classroom 302 is used as the target-associated classroom location information associated with the device identifier associated with device two; the classroom location information associated with the third classroom 303 is used as the target-associated classroom location information associated with the device identifier associated with device three; the classroom location information associated with the fourth classroom 304 is used as the target-associated classroom location information associated with the device identifier associated with device four; the classroom location information associated with the fifth classroom 305 is used as the target-associated classroom location information associated with the device identifier associated with device five; and the classroom location information associated with the sixth classroom 306 is used as the target-associated classroom location information associated with the device identifier associated with device six.

[0149] When receiving the user identification and the first time period information sent by the device 1 configured in the first classroom 301, the device identification associated with the device 1 is used as the first device identification, and the preset user identification set is determined from the time period library according to the first device identification and the current time. The user identification is verified using the preset user identification set, and when the user identification passes the verification, the preset time period information is obtained, and the first time period information is verified using the preset time period information, and when it is determined that the verification passes, the user identification is cancelled.

[0150] It should be noted that Figure 3 The number of devices and classrooms in the description is only used as an example and does not constitute any limitation to the embodiments of this description. In practice, any number of devices and classrooms may be used.

[0151] Figure 4 Shown is a schematic diagram of an attendance method according to another embodiment of the present specification.

[0152] According to another embodiment of the present specification, the attendance request is associated with the first device identifier, and according to the received attendance request, matching the user identifier with each preset user identifier in the preset user identifier set includes: matching the user identifier with each first sub-preset user identifier in the first sub-preset user identifier set associated with the first device identifier; when it is determined that the user identifier does not match any first sub-preset user identifier in the first sub-preset user identifier set, determining at least one target device identifier from the second device identifier set; obtaining the second sub-preset user identifier set associated with each target device identifier; and matching the user identifier with each second sub-user identifier in each of the second sub-preset user identifier sets.

[0153] The first sub-preset user identification set is a preset user identification corresponding to the first device identification. The second device identification set is composed of all device identifications in the preset area except the first device identification, and each of the device identifications is used as a second device identification.

[0154] When receiving an attendance request sent by a wifi device configured in a target associated classroom, the device identifier associated with the wifi device is used as the first device identifier, and based on the first device identifier and the current time, the first sub-preset user identifier set corresponding to the first device identifier is determined from the time period library. It is determined whether there is a target sub-preset user identifier consistent with the user identifier in the first sub-preset user identifier set. If it is determined that the target sub-preset identifier does not exist in the first sub-preset user identifier set, at least one target device identifier associated with the first device identifier is determined from the second device identifier set. Furthermore, based on each target device identifier, the corresponding second sub-preset user identifier set is determined, and the user identifier is verified using each second sub-preset user identifier set.

[0155] Perform a Wi-Fi connection test on the Wi-Fi device configured in the target associated classroom in advance, that is, whether the target associated classroom can be connected to the Wi-Fi device associated with the second device identifier, and determine whether the second device identifiers of the Wi-Fi devices associated with the second device identifier that can be connected are all associated with the first device identifier, so as to improve the efficiency and accuracy of attendance verification when students are taking classes in the target associated classroom and connect to the wrong Wi-Fi device or forget the name of the Wi-Fi device to be connected.

[0156] According to another embodiment of the present specification, determining at least one target device identification from a second device identification set includes: determining a first coverage range of a first device associated with a first device identification; determining a second coverage range of a second device associated with each second device identification in the second device identification set to obtain multiple second coverage ranges; determining at least one overlapping coverage area based on the first coverage range and the multiple second coverage ranges; and determining at least one target device identification based on the at least one overlapping coverage area.

[0157] The first coverage range represents the range of the wifi device corresponding to the first device identifier that can be connected within the preset area. The second coverage range represents the range of the wifi device corresponding to the second device identifier that can be connected within the preset area. The overlapping coverage area represents the area within the preset area that can be connected to both the wifi device corresponding to the first device identifier and the wifi device corresponding to the second device identifier. The overlapping coverage area can also be represented, for example, by the area within the target associated classroom area that can be connected to both the wifi device corresponding to the first device identifier and the wifi device corresponding to the second device identifier.

[0158] After the overlapping coverage area is determined, all second device identifiers corresponding to the overlapping coverage area are used as target device identifiers.

[0159] According to another embodiment of the present specification, determining a first coverage range of a first device associated with a first device identifier includes: acquiring a coverage radius and location information associated with the first device identifier; and determining the first coverage range within a preset area based on the location information and the coverage radius.

[0160] The coverage radius may be, for example, the connectable radius of the wifi device. The location information is the location of the wifi device in the preset area. In the preset area, based on the location information and the coverage radius, the first coverage range may be determined, for example, by taking the location information as the center and the coverage radius as the radius, and obtaining a circular area as the first coverage range. In the preset area, based on the location information and the coverage radius, the first coverage range may be determined, for example, by taking the location information as the center and the coverage radius as the radius, and obtaining a circular area; based on the loss ratio of the structures in the circular area, each boundary point on the circular area is corrected to obtain a corrected boundary point, and the first coverage range is obtained based on the corrected boundary point.

[0161] According to another embodiment of the present specification, determining at least one target device identification based on at least one overlapping coverage area includes: determining area data of each overlapping coverage area in at least one overlapping coverage area to obtain at least one area data; determining at least one target area data from the at least one area data; and determining a second device identification corresponding to each target area data as the target device identification.

[0162] Using the integral, each overlapping coverage area is calculated to obtain the area data of each overlapping coverage area. The at least one area data obtained is sorted in order from large to small, the area data of the preset ratio is determined as the target area data, and the second device identifier corresponding to each target area data is determined as the target device identifier. The preset ratio can be 80, for example. Thus, the wifi device that the students in the target associated classroom may be connected to is determined, and the user identifier corresponding to the student has been verified using the preset user identifier set corresponding to the wifi device, which improves the efficiency and accuracy of attendance verification when the students are in the target associated classroom and connect to the wrong wifi device or forget the name of the wifi device to be connected.

[0163] According to another embodiment of the present specification, determining at least one target area data from at least one area data includes: comparing each area data with a preset threshold; and determining area data greater than the preset threshold as the target area data.

[0164] like Figure 4 As shown, the preset area includes the first classroom 401, the second classroom 402, the third classroom 403, the fourth classroom 404, the fifth classroom 405 and the sixth classroom 406. Each classroom is equipped with a corresponding wifi device, and the device 1, device 2, device 3, device 4, device 5 and device 6 are respectively equipped in the first classroom 401, the second classroom 402, the third classroom 403, the fourth classroom 404, the fifth classroom 405 and the sixth classroom 406.

[0165] The classroom location information associated with the first classroom 401 is used as the target associated classroom location information associated with the device identifier associated with the device 1. Similarly, the classroom location information associated with the second classroom 302, the third classroom 403, the fourth classroom 404, the fifth classroom 405 and the sixth classroom 406 is used as the target associated classroom location information associated with the device identifiers associated with the devices 2, 3, 4, 5 and 6.

[0166] When receiving the attendance request sent by the device 1 configured in the first classroom 401, the device identification associated with the device 1 is used as the first device identification. The user identification included in the attendance request is verified using the first sub-preset user identification set corresponding to the first device identification.

[0167] In the case where the user identification verification fails, for device one, the first coverage range 411 is determined. The device identifications associated with device two, device three, device four, device five and device six are all used as second device identifications. For device two, device three, device four, device five and device six, the second coverage range 412, the second coverage range 413, the second coverage range 414, the second coverage range 415 and the second coverage range 416 are determined respectively. The overlapping coverage area of ​​the first coverage range 411 and each second coverage range is determined to obtain the overlapping coverage area 421 between the first coverage range 411 and the second coverage range 412, the overlapping coverage area 422 between the first coverage range 411 and the second coverage range 414, and the overlapping coverage area 423 between the first coverage range 411 and the second coverage range 415. The area data are calculated for the overlapping coverage area 421, the overlapping coverage area 422 and the overlapping coverage area 423 respectively. The target area data is determined from the three area data. For example, the target area data is the area data corresponding to the overlapping coverage area 421 and the overlapping coverage area 422 respectively. Then the second device identifiers corresponding to the device 2 and the device 4 respectively are used as the target device identifier.

[0168] The user identification is verified according to a second sub-preset user identification set corresponding to the target device identification.

[0169] It should be noted that Figure 4 The number of devices and classrooms in the description is only used as an example and does not constitute any limitation to the embodiments of this description. In practice, any number of devices and classrooms may be used.

[0170] Figure 5 Shown is a schematic diagram of an attendance method according to another embodiment of the present specification.

[0171] According to another embodiment of the present specification, after matching the user identifier with each preset user identifier in a preset user identifier set according to the received attendance request, it also includes: when it is determined that the attendance request does not meet the preset conditions, sending a class cancellation request to the client and associating the undetermined information with the user identifier, and when a modification instruction from the client is received, updating the undetermined information to attendance success information, wherein the preset conditions include determining that the user identifier matches at least one preset user identifier in the preset user identifier set, or the first time period information matches the preset time period information.

[0172] The undetermined message includes any message other than the attendance success message, such as the attendance failure message, the waiting verification message, and the verifying message. The client may be, for example, a client used by a user who registers for a course. The modification instruction includes information that can be verified by the user identification and the first time period information. For example, it may include the proof of attendance with a signature uploaded by the user through the client and other certification materials that connect the user identification and the corresponding first device identification.

[0173] like Figure 5 As shown, for the target associated classroom 511, a first device 501 (wifi) is configured. The first device 501 is connected to the server 502 through a network to ensure communication. For example, when a user wants to register for a target course, the first user terminal 504 can be used to send a registration request to the server 502. When the server 502 receives the registration request, it verifies the registration request, and after the verification is passed, it sends an address request to the first user terminal 504. The address request includes a request for the user to enter the address information of the second user terminal 503 that the user carries when attending offline classes. When the user receives the address request, the address information of the second user terminal is sent to the server 502. It should be noted that Figure 5 In the example, the terminal device used by the user for registration and the terminal device carried to the class are different terminal devices, but the terminal device used by the user for registration and the terminal device carried to the class can also be the same terminal device. In the case of the same terminal device, the first user terminal 504 sends the address information of the first user terminal to the server.

[0174] After scheduling classes based on the address information received from the second user terminal, the server 502 associates the target course time period and the address information with the first device identifier corresponding to the first device 501 .

[0175] During the target course time period, the student who needs to attend the class brings the second user terminal 503 to the target associated classroom 511, and uses the second user terminal 503 to connect to the first device 501 (wifi). After the target course is over, the student uses the second user terminal 503 to disconnect from the first device 501 (wifi), or leaves the target associated classroom 511, so as to automatically disconnect the second user terminal 503 from the first device 501 (wifi). The first device 501 (wifi) records the start connection time and the end connection time and the address information corresponding to the second user terminal 503, and sends the start connection time and the end connection time and the address information corresponding to the second user terminal 503 as an attendance request to the server 502. The server 502 verifies the attendance request, and if the verification fails, sends a cancellation request to the first user terminal 504, and associates the undetermined information with the address information corresponding to the second user terminal 503. After receiving the cancellation request, if the first user terminal 504 has any objection to the cancellation request, it uploads a modification request. After receiving the modification request, the server 502 verifies the modification request. If the modification request passes the verification, the server 502 determines that the modification request is a modification instruction and modifies the undetermined information into attendance success information. Figure 5 In the example, the attendance request verification failure is taken as an example. However, when the attendance request verification is successful on the server 502, the attendance success information is associated with the user ID.

[0176] It should be noted that Figure 5 The number of the first user terminal, the second user terminal, the first device and the target associated classroom is only used as an example and does not constitute any limitation to the embodiments of this description. In practice, any number of the first user terminal, the second user terminal, the first device and the target associated classroom can be used.
