Description

Technical Field

[0001] This application relates to the field of mobile Internet location service technology, and in particular to an attendance method, device and computer equipment. Background Technology

[0002] Mobile attendance tracking avoids the need for dedicated hardware; employees can complete attendance checks using only their smartphones, significantly simplifying the process, improving efficiency, and offering advantages such as convenience, low cost, and ease of deployment. However, in scenarios like corporate training attendance, the temporary and variable nature of the check-in location presents challenges. Firstly, while traditional wireless fingerprint recognition methods offer high accuracy, they require pre-collecting signal fingerprints and maintaining a static fingerprint database. For frequently changing check-in locations, this method is costly and inflexible. Secondly, indoor positioning signals can be obstructed or drift, and are susceptible to software tampering and remote proxy signing, making accurate attendance statistics difficult. Therefore, a new attendance method, device, and computer equipment are urgently needed to overcome these problems. Summary of the Invention

[0003] To address the challenges of establishing an environmental signal fingerprint database, location signal deviation, and susceptibility to tampering encountered when using mobile terminals for attendance tracking, this application provides the following technical solutions.

[0004] Firstly, an attendance method is provided, including: In response to receiving an attendance request initiated by the first terminal, the system obtains a list of first signals identified by the first terminal, wherein the list of first signals includes the first wireless local area communication signal identified by the first terminal.

[0005] Based on the first signal list, determine the attendance reference signal list.

[0006] Based on the attendance reference signal list, a similarity threshold is determined, which is used to determine whether the check-in request from the second terminal is valid.

[0007] The system receives a check-in request from the second terminal and obtains a list of second signals identified by the second terminal, wherein the list of second signals includes second wireless local area communication signals identified by the second terminal.

[0008] The response result for the check-in request is determined based on the attendance reference signal list, the second signal list, and the similarity threshold.

[0009] Further, based on the first signal list, an attendance reference signal list is determined, including: Obtain the organization unique identifier of the device that generates any first wireless local area communication signal in the first signal list.

[0010] According to the organization unique identifier, filter out the fixed device signal list from the first signal list, where the fixed device signal list includes fixed device signals, and the fixed device signals are wireless local area communication signals generated by fixed devices.

[0011] Determine the attendance reference signal list according to the fixed device signal list.

[0012] Further, determining the attendance reference signal list according to the fixed device signal list includes: Generate an attendance reference signal list based on any fixed device signal in the fixed device signal list.

[0013] Further, determining the attendance reference signal list according to the fixed device signal list further includes: Send the fixed device signal list to the first terminal for the user of the first terminal to select and feedback at least one fixed device signal.

[0014] Obtain at least one fixed device signal feedback by the user of the first terminal.

[0015] Generate an attendance reference signal list based on at least one fixed device signal.

[0016] Further, the attendance reference signal list includes at least one attendance reference signal. According to the attendance reference signal list, determining the similarity threshold includes: In response to N S < N, then take the product of the number of attendance reference signals and the base weight as the similarity threshold, where N S represents the number of attendance reference signals in the attendance reference signal list, and N is a preset number.

[0017] In response to N S ≥ N, then take the similarity preset value as the similarity threshold.

[0018] Further, according to the attendance reference signal list, the second signal list, and the similarity threshold, determining the response result of the check-in request includes: Traverse the second wireless local area communication signals in the second signal list, compare any second wireless local area communication signal with the attendance reference list, and determine the matching score of the second wireless local area communication signal. [[ID= forty-two]]

[0019] According to the matching score of any second wireless local area communication signal in the second signal list, determine the total matching score corresponding to the check-in request. >

[0020] Compare the total matching score with the similarity threshold.

[0021] In response to the total matching score being greater than the similarity threshold, the first result is used as the response result, where the first result is used to indicate successful check-in.

[0022] Furthermore, comparing any second wireless local area communication signal with the attendance reference list to determine the matching score of the second wireless local area communication signal includes: According to: S i = M i · (W B + W R · P i ), determine the matching score of the second wireless local area communication signal, where S i represents the matching score of the second wireless local area communication signal, i is a natural number used to correspond to the second wireless local area communication signal in the second signal list, W B represents the basic weight, W R represents the precision weight, M i takes a value of 0 or 1. When M i takes a value of 0, it means that the second wireless local area communication signal does not exist in the attendance reference list. When M i takes a value of 1, it means that the second wireless local area communication signal exists in the attendance reference list. P i takes a value of 0 or 1. When P i takes a value of 0, it means that: |R T - R S | ≥ R. When P i takes a value of 1, it means that: |R T - R S | < R, where R T represents the signal strength recognized by the first terminal for the signal corresponding to the second wireless local area communication signal in the attendance reference list, R S represents the signal strength recognized by the second terminal for the second wireless local area communication signal, and R represents the signal strength difference threshold.

[0023] Furthermore, the attendance method further includes: In response to the response result being the second result, record the second result in the log, and / or send a prompt message to the second terminal, where the second result is used to indicate failed check-in.

[0024] In a second aspect, an attendance device is provided, including: A first signal acquisition module, configured to, in response to receiving an attendance request initiated by a first terminal, acquire a first signal list recognized by the first terminal, where the first signal list includes a first wireless local area communication signal recognized by the first terminal.

[0025] The reference list generation module is used to determine the attendance reference signal list based on the first signal list.

[0026] The threshold determination module is used to determine the similarity threshold based on the attendance reference signal list. The similarity threshold is used to determine whether the check-in request of the second terminal is valid.

[0027] The second signal acquisition module is used to receive the check-in request from the second terminal and acquire the second signal list identified by the second terminal, wherein the second signal list includes the second wireless local area communication signal identified by the second terminal.

[0028] The attendance determination module is used to determine the response result of the check-in request based on the attendance reference signal list, the second signal list, and the similarity threshold.

[0029] Thirdly, a computer device is provided, including a memory, a processor, and an attendance program stored in the memory and executable on the processor. When the processor executes the attendance program, it implements the attendance method described in the first aspect.

[0030] Fourthly, a computer-readable storage medium is provided, on which an attendance program is stored, wherein when the attendance program is executed by a processor, the attendance method described in the first aspect is implemented.

[0031] Fifthly, a computer program product is provided, including a computer program that, when executed by a processor, implements the attendance method described in the first aspect.

[0032] The beneficial effects of the technical solution provided in this application are as follows: By implementing the attendance method, apparatus, and computer equipment disclosed in this application, dynamic attendance reference signals and similarity thresholds can be generated based on the first signal list identified by the first terminal. These signals are then compared with the second signal list identified by the second terminal to verify whether the second terminal performing attendance check-in is in the same physical environment. This achieves an attendance mechanism that does not rely on a preset signal fingerprint database, requires no positioning signals, and is suitable for temporary locations. By establishing a "relative reference system" of wireless local area communication signals to replace the "absolute position" of the check-in terminal, the accuracy of indoor attendance can be improved. This eliminates the need for pre-deploying an environmental fingerprint database, avoids inaccurate indoor positioning, and prevents remote proxy check-in. Attached Figure Description

[0037] The various embodiments according to this disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that in the drawings, the same reference numerals are assigned to components having substantially the same or similar structure and function, and repeated descriptions of them will be omitted.

[0038] To address the problems of establishing an environmental signal fingerprint database, location signal deviation, and susceptibility to tampering when using mobile terminals for attendance tracking, this application provides the following embodiments: In some embodiments, such as Figure 1 As shown, an attendance method includes: S100: In response to receiving an attendance request initiated by the first terminal, the system obtains a list of first signals identified by the first terminal, wherein the list of first signals includes the first wireless local area communication signal identified by the first terminal.

[0039] S200: Determine the attendance reference signal list based on the first signal list.

[0040] S300: Determine the similarity threshold based on the attendance reference signal list. The similarity threshold is used to determine whether the check-in request of the second terminal is valid.

[0041] S400: Receives the check-in request from the second terminal and obtains the second signal list identified by the second terminal, wherein the second signal list includes the second wireless local area communication signal identified by the second terminal.

[0042] S500: Determine the response result of the check-in request based on the attendance reference signal list, the second signal list, and the similarity threshold.

[0043] The first terminal refers to the terminal device that initiates the attendance request. This terminal device communicates with the management backend via a network and is at least capable of searching for existing wireless local area communication signals in the space. It can be a personal computer equipped with a wireless network card, or a mobile terminal such as a smartphone, tablet, or laptop. A smartphone is preferred.

[0044] In this application, the management backend can execute the aforementioned attendance method. Before executing the attendance method, it grants the terminal device the permission of a first terminal, namely, the permission to initiate an attendance request. The management backend records the personnel and their corresponding terminal devices. Based on the actual check-in scenario, it grants a certain person's corresponding terminal device the permission of a first terminal, enabling them to initiate a check-in request. For example, in a certain class, there are three participants: A, B, and C. Among them, A is the teacher of this class, and B and C are students. The management backend will grant A the permission to initiate a check-in request so that B and C can check in. In this scenario, the terminal device corresponding to A is the first terminal, and the terminal devices corresponding to B and C are both second terminals.

[0045] Wireless local area communication (WLAN) signals refer to communication signals that enable data transmission between devices via radio waves within a limited spatial range. They are used to construct wireless local area networks (WLANs) or for short-range point-to-point or point-to-multipoint communication. Illustratively, WiFi signals, Bluetooth signals, Zigbee signals, Z-Wave signals, and UWB signals all fall under this category. Among these, WiFi and Bluetooth signals are the most widely used. This application will use WiFi signals as an example to illustrate the implementation method, but it does not limit the technical solutions implemented using other signals besides WiFi.

[0046] The first wireless local area communication signal refers to the wireless local area communication signal identified by the first terminal. Taking WiFi signals as an example, the first terminal identifies the first wireless local area communication signal by actively scanning the wireless signals broadcast by access points (APs) in the surrounding environment through the wireless network card or WiFi chip built into the first terminal. First, the phone's WiFi chip listens to each channel on the 2.4GHz and / or 5GHz frequency bands in the background or when triggered by the user; it sends "probe request" frames to inquire about nearby WiFi networks; after receiving the frames, the surrounding access points reply with "beacon frames" or periodically broadcast beacon frames. Second, the operating system of the first terminal (e.g., Android / iOS) organizes the received information into a WiFi scan result list. Subsequently, this scan result list is organized into the first signal list.

[0047] An access point is a network device that provides a bridge for wireless devices to connect to a wired network or the Internet. Common access points are fixed devices (such as wireless routers) or WiFi hotspot devices. WiFi hotspot devices are devices with cellular network connectivity and support network sharing functions. Common WiFi hotspot devices include: smartphones, dedicated mobile hotspot devices (such as MiFi devices), cellular routers, tablets, laptops, combinations of USB cellular network cards and computers, in-vehicle hotspot systems, IoT gateway devices, smartwatches, emergency communication devices, and portable base stations. In this application, WiFi hotspot devices will be excluded from the attendance reference signal list.

[0048] The attendance reference signal list, in this embodiment of the application, is a list of signals used in conjunction with a similarity threshold to compare whether the second terminal has performed a valid attendance check-in. Its specific content will be described in detail below.

[0049] In this embodiment, the second terminal is used for check-in. Preferably, it is a mobile terminal. Indicatively, the second terminal can be a smartphone, tablet computer (PAD), laptop computer, smartwatch, or other similar device.

[0050] The second wireless local area communication signal refers to the wireless local area communication signal identified by the second terminal.

[0051] The response to the check-in request is a prompt indicating whether the check-in was successful or failed. This application does not specify the specific format.

[0052] By implementing the above method, dynamic attendance reference signals and similarity thresholds can be generated based on the first signal list identified by the first terminal. These signals are then compared with the second signal list identified by the second terminal to verify whether the second terminal performing attendance check-in is in the same physical environment. This achieves an attendance mechanism that does not rely on a preset signal fingerprint database, requires no location signals, and is suitable for temporary locations. By establishing a wireless local area communication signal comparison mechanism, indoor attendance accuracy is improved.

[0053] Specifically, S200: Based on the first signal list, determine the attendance reference signal list, including: S210: Obtain the organization-unique identifier of the device that generates any of the first wireless local area communication signals in the first signal list.

[0054] S220: Based on the organization's unique identifier, filter the first signal list to obtain a fixed device signal list, wherein the fixed device signal list includes fixed device signals, which are wireless local area communication signals generated by fixed devices.

[0055] S230: Determine the attendance reference signal list based on the fixed equipment signal list.

[0056] The device that generates any of the first wireless local area communication signals in the first signal list includes: fixed devices and WiFi hotspot devices.

[0057] An Organizationally Unique Identifier (OUI) is a 24-bit (6 hexadecimal characters) unique prefix assigned by the IEEE (Institute of Electrical and Electronics Engineers) to equipment manufacturers to identify the manufacturer of network equipment.

[0058] The signals included in the fixed equipment signal list are all generated by fixed equipment in the surrounding environment.

[0059] The OUI of a fixed device can be obtained by querying the official IEEE OUI database or a public database. The first 6 characters of the MAC address are then compared with the hexadecimal value to filter fixed devices.

[0060] To illustrate, the OUI of common device manufacturers is as follows: Apple iPhone: AC:DE:48, FC:EC:DA; Samsung phones: D0: 22: BE, A4: 77: 33; Huawei phones: 2C:5B:B8, BC:92:6B; TP-Link: F4: 8E: 09.

[0061] In this application, signals such as those from TP-Link are generated by fixed devices, while signals from Apple, Samsung, and Huawei phones are WiFi hotspots. Devices from other manufacturers can be found by looking up their corresponding OUI tables, and are not listed here.

[0062] The pseudocode for implementing the above process is as follows: public boolean verify(Fingerprint teacher, Fingerprint student) { / / Filter mobile hotspots (Anti-Hotspot) filterMobileHotspots(teacher); filterMobileHotspots(student); By identifying and extracting WiFi hotspot signals using the organization's unique identifier in the MAC address, only signals emitted by fixed devices are retained as attendance reference signals. This improves the stability and spatial uniqueness of environmental fingerprinting, avoiding misjudgments caused by interference from temporary mobile devices.

[0063] Optionally, the attendance reference signal list can be determined based on the fixed equipment signal list in two ways: Firstly: S231a: Generate an attendance reference signal list based on any fixed equipment signal in the fixed equipment signal list.

[0064] That is, all signals in the fixed equipment signal list can be used as attendance reference signals.

[0065] Secondly: S231b: Send a list of fixed device signals to the first terminal so that the user of the first terminal can select and provide feedback on at least one fixed device signal.

[0066] S232b: Acquire at least one fixed device signal from user feedback at the first terminal.

[0067] S233b: Generate a list of attendance reference signals based on signals from at least one fixed device.

[0068] The first end user selects a portion of the fixed equipment signal list as the attendance reference signal.

[0069] Teachers, as the primary end-users, can improve the flexibility of attendance reference signal selection by filtering the fixed equipment signal list. This makes the sign-in verification conditions more stringent, thereby improving the accuracy of student sign-in.

[0070] The attendance reference signal list includes at least one attendance reference signal. Specifically, S300: determining a similarity threshold according to the attendance reference signal list, including: S310: in response to N S < N, then take the product of the number of attendance reference signals and the base weight as the similarity threshold, where N S represents the number of attendance reference signals in the attendance reference signal list, and N is a preset number.

[0071] S320: in response to N S ≥ N, then take the similarity preset value as the similarity threshold.

[0072] Schematically, the base weight is 20, the similarity preset value is 60, and the preset number N = 3.

[0073] When N S = 2, that is, the number of attendance reference signals in the attendance reference signal list is 2, and the similarity threshold is 40; When N S = 4, the similarity threshold is 60.

[0074] The pseudo-code for implementing the above process is: / / Dynamically calculate the threshold double threshold = calculateDynamicThreshold(teacher.size()); According to the number N of attendance reference signals in the attendance reference signal list S Adaptively adjust the passing threshold, so that full matching is required when the signals are sparse, and a fixed standard score is adopted when the signals are rich. Solve the problem of different WiFi coverage densities in different venues, and avoid false rejections due to too high thresholds in environments with few signals (such as small meeting rooms), or false acceptances due to too low thresholds in environments with many signals; improve the robustness and universality of the system.

[0075] S500: determining the response result of the check-in request according to the attendance reference signal list, the second signal list, and the similarity threshold, including: S510: Traverse the second wireless local area communication signals in the second signal list, compare any second wireless local area communication signal with the attendance reference list, and determine the matching score of the second wireless local area communication signal.

[0076] S520: Determine the total matching score corresponding to the check-in request according to the matching score of any second wireless local area communication signal in the second signal list.

[0077] S530: Compare the total matching score with the similarity threshold.

[0078] S540: If the total matching score is greater than the similarity threshold, the first result is used as the response result, where the first result is used to indicate successful check-in.

[0079] Compare the student signal with the attendance reference list item by item, accumulate the scores, and compare with the dynamic similarity threshold to finally determine whether the check-in is valid. Implement a quantitative and configurable verification logic to make the attendance result have an objective basis.

[0080] Specifically, compare any second wireless local area communication signal with the attendance reference list to determine the matching score of the second wireless local area communication signal, including: According to: S i = M i · (W B + W R · P i ), determine the matching score of the second wireless local area communication signal, where S i represents the matching score of the second wireless local area communication signal, i is a natural number used to correspond to the second wireless local area communication signal in the second signal list, W<s B represents the basic weight, W R represents the precision weight, M i takes a value of 0 or 1. When the value of M i ]>is 0, it means that the second wireless local area communication signal does not exist in the attendance reference list. When the value of M i is 1, it means that the second wireless local area communication signal exists in the attendance reference list. P i takes a value of O or 1. When the value of P i is 0, it means that: |R T - R S | ≥ R. When the value of P i is 1, it means that: |R T - R S | < R, where R T represents the signal strength of the signal corresponding to the second wireless local area communication signal in the attendance reference list recognized by the first terminal, R S represents the signal strength of the second wireless local area communication signal recognized by the second terminal, and R represents the signal strength difference threshold.

[0081] Optionally, set the value of R to 15.

[0082] Schematically, Teacher A scans the WiFi signals around the space and gets the following results: <00​​​​Next, verify the signal strength differences of F4:8E:09:A1:B2:C3 and 64:70:02:11:22:33 respectively.

[0084] The signal strength difference between F4:8E:09:A1:B2:C3 is: | -55 – (-58)| = 3 dBm, which is a precision match.

[0085] The signal strength difference at 64:70:02:11:22:33 is: | -60 - (-62)| = 2 dBm, which is a precision match.

[0086] Its S1 = 60, while the corresponding similarity threshold is 40. Student B has passed the check-in.

[0087] Trainee C, whose actual location is 20 meters away from the conference room, has the following scan results: Student C only scanned “F4:8E:09:A1:B2:C3”, but not “64:70:02:11:22:33”.

[0088] The signal strength difference between F4:8E:09:A1:B2:C3 is: | -85 – (-58)| = 30 dBm > 15 dBm. Precision mismatch.

[0089] Therefore, student C's score S2 = 20, corresponding to a similarity threshold of 40. Student C's attendance check-in is unsuccessful.

[0090] For each matched wireless signal, both an existence score (whether it is in the reference list) and a distance accuracy score (whether the RSSI difference is within the tolerance) are calculated simultaneously and then summed with weights.

[0091] The pseudocode for implementing the above process is as follows: / / Calculate weighted score double score = 0; for (AP ap : student.getAccessPoints()) { AP ref = teacher.findAP(ap.bssid); if (ref != null) { score += WEIGHT_BASE; / / Base overlap score / / Signal attenuation verification if (Math.abs(ref.rssi - ap.rssi) <RSSI_TOLERANCE) { score += WEIGHT_PRECISION; / / Distance precision score } } } return score>= threshold; } The dual verification mechanism of signal overlap and signal strength difference significantly improves the accuracy of location determination and effectively resists cheating behaviors such as "remote signing" and "signal forgery".

[0092] Preferably, the attendance method further includes: S600: If the response result is the second result, then the second result will be recorded in the log. And / or send a notification message to a second terminal, wherein the second result is used to indicate that the check-in failed.

[0093] The logs retain the check-in results from the second terminal. Preferably, the management backend can also send the check-in results to the corresponding second terminal, reminding the relevant user to complete the check-in.

[0094] Logging out failed check-in attempts and / or sending notifications to users can improve system maintainability and user experience. Logs facilitate post-event auditing and troubleshooting, and real-time notifications can help users retry or contact the administrator promptly.

[0095] By implementing the attendance method, apparatus, and computer equipment disclosed in this application, dynamic attendance reference signals and similarity thresholds can be generated based on a first signal list identified by a first terminal. These signals are then compared with a second signal list identified by a second terminal to verify whether the second terminal performing attendance check-in is in the same physical environment. This achieves an attendance mechanism that does not rely on a preset signal fingerprint database, requires no positioning signals, and is suitable for temporary locations. By establishing a "relative reference system" of wireless local area communication signals to replace the "absolute position" of the check-in terminal, indoor attendance accuracy can be improved. This eliminates the need for pre-deployment of an environmental fingerprint database, avoids inaccurate indoor positioning, and prevents remote proxy check-in.

[0096] It should be understood that, although Figure 1 The steps in the flowchart are shown sequentially as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order in which these steps are executed, and they can be performed in other orders. Figure 1At least some of the steps in the process may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least some of the sub-steps or stages of other steps.

[0097] In other embodiments, such as Figure 2 As shown, an attendance device includes: The first signal acquisition module is used to, in response to receiving an attendance request initiated by the first terminal, acquire a first signal list identified by the first terminal, wherein the first signal list includes a first wireless local area communication signal identified by the first terminal.

[0098] The reference list generation module is used to determine the attendance reference signal list based on the first signal list.

[0099] The threshold determination module is used to determine the similarity threshold based on the attendance reference signal list. The similarity threshold is used to determine whether the check-in request of the second terminal is valid.

[0100] The second signal acquisition module is used to receive the check-in request from the second terminal and acquire the second signal list identified by the second terminal, wherein the second signal list includes the second wireless local area communication signal identified by the second terminal.

[0101] The attendance determination module is used to determine the response result of the check-in request based on the attendance reference signal list, the second signal list, and the similarity threshold.

[0102] By implementing the attendance device disclosed in the embodiments of this application, dynamic attendance reference signals and similarity thresholds can be generated based on a first signal list identified by a first terminal. These signals are then compared with a second signal list identified by a second terminal to verify whether the second terminal performing attendance check-in is in the same physical environment. This achieves an attendance mechanism that does not rely on a preset signal fingerprint database, requires no positioning signals, and is suitable for temporary locations. By establishing a comparison mechanism for wireless local area communication signals, the accuracy of indoor attendance is improved.

[0103] For specific limitations regarding the attendance device described above, please refer to the limitations on the attendance method above; they will not be repeated here. Each module in the aforementioned attendance device can be implemented entirely or partially through software, hardware, or a combination thereof. These modules can be embedded in or independent of the processor in the computer device in hardware form, or stored in the memory of the computer device in software form, so that the processor can call and execute the corresponding operations of each module.

[0104] In other embodiments, such as Figure 3 As shown, a computer device includes a memory, a processor, and an attendance program stored in the memory and executable on the processor. When the processor executes the attendance program, it implements the attendance method described above. Specifically, it includes: S100: In response to receiving an attendance request initiated by the first terminal, the system obtains a list of first signals identified by the first terminal, wherein the list of first signals includes the first wireless local area communication signal identified by the first terminal.

[0105] S200: Determine the attendance reference signal list based on the first signal list.
