Specifically, the first server may provide an attendance management service by interworking with each of the terminals 10, 20, 30, and 40 through at least one web page or application.

The second server 200 is a server for authenticating consent and/or approval for an absence report (absence request or absence report), early leave request, and the like.

The second server 200 may be implemented in the form of a system each including a server for performing authentication, a server for registering and managing signatures, and the like.

When the guardian's signature for agreeing to at least one absence notice is received through the guardian terminal 20, the second server 200 may perform authentication on the corresponding signature.

In addition, the second server 200 may perform authentication on signatures received through each of the teacher terminal 30 and/or the manager terminal 40 in order to approve the absence report.

The third server 300 may verify the validity of each signature authenticated through the second server 200 and update attendance information according to the absence record.

The attendance information includes information on each student's daily attendance, absence, early departure, truancy, and early departure without notice. Attendance information may be registered separately for each certain period (ex. semester, year).

Attendance information may be stored on the third server 300 or at least one server communicable with the third server 300 .

The student terminal 10 is a terminal device of a student who is the subject of attendance, and the guardian terminal 20 is a terminal device of a guardian of the student terminal 10 . The teacher terminal 30 is a terminal device of a student in charge or a homeroom teacher, and the manager terminal 40 is a terminal device of a person in charge (eg, principal, assistant principal, etc.) who is responsible for managing attendance information.

Each terminal may correspond to various terminal devices such as a smart phone, a tablet PC, a notebook PC, a desktop PC, a PDA, and a wearable device, but is not limited thereto.

2 is a flowchart illustrating a method for managing attendance of a system according to an embodiment of the present disclosure.

FIG. 2 assumes a situation in which an absence report is received from the student terminal 10 through an application or web page provided by the first server 100 .

The first server 100 based on the student's input received through the student terminal 10, the target date, report type (ex. absent, late, early leave, result, etc.), and report reason (ex. disease, appeal) etc.) can be received. In addition, the first server 100 may upload at least one evidential document to prove the reason for reporting according to the student's input received through the student terminal 10 .

And, referring to FIG. 2 , the first server 100 may transmit the absence report received from the student terminal 10 to the guardian terminal 20 that matches the student terminal 10 (S210).

In this case, the first server 100 may identify information about the guardian terminal 20 according to the student's input received through the student terminal 10 . Information on the guardian terminal 20 may include the contact information (eg, mobile phone number) of the guardian terminal 20 .

In addition, the first server 100 may obtain information about the guardian (eg, name, relationship with the student, etc.) according to the student's input.

In addition, the first server 100 may transmit a message requesting a signature for agreeing to the absence report to the contact information of the guardian terminal 20 . In this case, the first server 100 may transmit the absence report (target date, report type, report reason, etc.) to the guardian terminal 20 together.

As a result, the guardian terminal 20 may output information and a message about the absence system.

In this case, according to the request of the first server 100 and/or the guardian terminal 20, the second server 200 may interoperate with the guardian terminal 20.

At this time, the second server 200 may perform authentication on the guardian's first signature for agreeing to the absence notice (S220). Specifically, the second server 200 may compare the registered guardian's signature with the input guardian's first signature, and may identify that authentication is successful on the premise that the matching degree is equal to or greater than a threshold value.

When authentication of the first signature fails or the first signature is not input, the second server 200 may transmit information indicating that authentication has failed to the first server 100 . As a result, the first server 100 may transmit to the student terminal 10 a message informing that consent of the guardian for the absence report has not been obtained.

On the other hand, when the authentication of the first signature is performed, the first server 100 may transmit an absentee report to the teacher terminal 20 (S230).

In this case, according to the request of the first server 100 and/or the teacher terminal 30 , the second server 200 may interwork with the teacher terminal 30 .

At this time, the second server 200 may perform authentication on the teacher's second signature for approving the absence report (S240). Specifically, the second server 200 may compare the registered teacher's signature with the input teacher's second signature, and may identify that authentication has been successful on the premise that the degree of matching is equal to or greater than a critical value.

When authentication of the second signature fails or the second signature is not input, the second server 200 may transmit information indicating that authentication has failed to the first server 100 . As a result, the first server 100 may transmit a message informing that the teacher's approval for the absence report has not been obtained to the student terminal 10 and the guardian terminal 20 . In this case, the first server 100 may transmit the contact information of the teacher terminal 30 to the guardian terminal 20 according to the guardian's request received through the guardian terminal 20 .

Alternatively, when an input of a teacher rejecting an absence report is received through the teacher terminal 30 , the first server 100 may transmit information indicating that the absence report has been rejected to the guardian terminal 20 . In this case, the first server 100 may transmit the contact information of the teacher terminal 30 to the guardian terminal 20 according to the guardian's request received through the guardian terminal 20 .

When authentication of the teacher's second signature for approving the absence report is performed, the first server 100 may transmit the absence report to the manager terminal 40 (S250).

In this case, according to the request of the first server 100 and/or the manager terminal 40 , the second server 200 may interwork with the manager terminal 40 .

At this time, the second server 200 may perform authentication for the third signature of the person in charge terminal 40 for approving the absence report (S260). Specifically, the second server 200 may compare the previously registered signature of the person in charge with the input third signature of the person in charge, and may identify that the authentication is successful on the premise that the degree of matching is equal to or greater than a critical value.

When authentication of the third signature is performed, the first server 100 may transmit an absentee report to the third server 300 (S270).

In addition, the first server 100 and/or the second server 200 may transmit the input first to third signatures to the third server 300 .

In this case, the third server 300 may verify the validity of each signature, and may update attendance information according to the absence report on the premise that validity is verified (S280).

Specifically, the third server 300 may verify the validity of each signature through information about the input time of each signature and the terminal to which each signature was input.

For example, the third server 300 determines each signature according to whether the first signature, the second signature, and the third signature are sequentially received after the time when the application for absenteeism is received from the student terminal 10. validity can be verified.

In addition, the third server 300 checks whether the first signature, the second signature, and the third signature are input on the guardian terminal 20, the teacher terminal 30, and the manager terminal 40, respectively, so that each signature is valid. can also be verified.

The third server 300 may determine whether the signature is forged by using at least one artificial intelligence model trained to detect whether the signature is forged or not. This artificial intelligence model can be trained based on a pair of training data consisting of a real signature (image) and a forged signature (image) of the real signature, and CNN (Convolutional Neural Network) for outputting a judgment result through feature information of the image. ), but is not limited thereto.

When validation is performed, the third server 300 may update the attendance information by changing the attendance information of the student on the corresponding day according to the absence report.

Meanwhile, FIG. 3 is a diagram for explaining an operation of a system that provides a user interface (UI) for submitting an absence report through a student terminal according to an embodiment of the present disclosure. 3 illustrates a situation in which an absence report is received through the student terminal 10 .

Referring to FIG. 3 , the first server 100 may provide a UI 310 including various menus related to attendance management services of (logged-in) students through the student terminal 10 .

When a user's input for selecting the "reason for attendance" item in the UI 310 is received, the first server 100 inputs information about the absence report (target date, report type, report reason, etc.) through the student terminal 10. A UI 320 for receiving may be provided.

And, if “submit” is selected, the first server 100 may receive input of information (contact information) on the guardian terminal through the UI 330 . And, the first server 100 may transmit information about the absence record to the guardian terminal of the corresponding contact.

4 is a diagram for explaining the operation of a system that provides a UI related to consent of an absentee system through a guardian terminal according to an embodiment of the present disclosure.

Referring to FIG. 4 , the first server 100 may transmit a message 410 requesting a signature for the absence report to the guardian terminal 20 .

Here, when “Confirm contents and sign” is selected according to the user input received through the guardian terminal 20, the first server 100 displays a UI including information about the absence report through the guardian terminal 20 ( 420) can be provided.

At this time, as the item "Confirm contents and sign (421)" is selected, the first server 100 provides a UI 430 for receiving the signature of the guardian (parent) agreeing to the absence report through the guardian terminal 20. can provide.

Here, the conditions for providing the UI 430 may be set according to the time point when the guardian's intention to sign is confirmed.

For example, when the guardian's signature intention to agree to the absence notice is entered within a predetermined time (ex. 30 minutes, 1 hour, etc.) from the time the message 410 is transmitted (: "Check the contents and sign" (421 ) is selected), the first server 100 may provide a UI 430 for receiving the guardian's signature through the guardian terminal 20 .

On the other hand, when the guardian's signature intention to agree to the absence notice is input after a predetermined time from the time when the message 410 is transmitted, the first server 100, through the guardian terminal 20, indicates that the absence notice has expired. can inform

As such, if the absence report is set to expire according to the time point at which the guardian's signature intention is input, administrative procedures after the absence report request can be managed relatively quickly/accurately.

Referring to FIG. 4 , when a guardian's signature is input through the UI 430, the second server 200 interworking with the first server 100 may perform authentication of the input signature.

5 is a diagram for explaining an operation of a system that provides a UI related to approval of an absence report through a teacher terminal according to an embodiment of the present disclosure.

5 illustrates an example of a screen of the teacher terminal 30 in the process of approving an absence report.

Referring to FIG. 5 , the first server 100 may provide a UI 510 representing login information and a UI 520 including menu items through the teacher terminal 30 .

Here, when the electronic payment system 521 item is selected, information 530 about an absence report received from at least one student terminal may be provided.

In addition, a UI 535 indicating a payment procedure may be provided together.

Here, if the teacher's signature is input through the UI 540 for receiving a signature for approving the absence report, the second server 200 linked with the first server 100 may perform authentication for the corresponding signature. .

Similar to the screen of the teacher terminal 30 shown in FIG. 5 , similar UIs may be provided through the manager terminal 40 , and authentication may be performed according to the signature of the manager.

Meanwhile, FIG. 6 is a diagram for explaining an operation of a system providing an attendance management service screen through a teacher terminal according to an embodiment of the present disclosure.

6 corresponds to a screen of an attendance management service provided through the teacher terminal 30 when attendance management 522 is selected from menu items.

Referring to FIG. 6 , the first server 100 may provide a UI 610 for selecting at least one absence system through the teacher terminal 30 . Specifically, a target year, target class (grade/class), report type, etc. may be selected through the UI 610 .

And, according to the selection result, at least one absence record item 620 may be provided. Within this category, information regarding the type of report of absence, target date, reporter (student), approval status, etc. may be included.

And, if the corresponding absence record item 620 is selected, a UI 630 including more detailed information on the absence record may be provided. The UI 630 may provide at least one evidential document file in addition to the guardian's name, reason for reporting, and details of the reason for reporting.

Meanwhile, when an absence report is received from the student terminal 10 , the first server 100 may obtain a student's attendance record of the student terminal 10 .

Specifically, the first server 100 may identify a student's attendance history for a certain period of time (eg, a certain period before the time when the absence report is received) based on the attendance information registered in the third server 300. .

In this case, the first server 100 may identify the student's attendance level according to the student's attendance history.

Here, the first server 100 may identify the student's absenteeism frequency according to the student's attendance history, and may determine a lower attendance grade as the absenteeism frequency increases.

As a specific example, when the identified absenteeism frequency is less than the critical value, the first server 100 may identify the student's attendance grade as the first grade. On the other hand, when the identified absentee frequency is greater than or equal to the threshold value, the first server 100 may identify the student's attendance grade as the second grade.

Also, the first server 100 may set a different payment process according to the student's attendance level.

In relation to this, FIG. 7 is an algorithm for explaining an operation in which the system according to an embodiment of the present disclosure varies a payment procedure for an absence account according to the frequency of absences of students.

Referring to FIG. 7 , when an absence report is received from the student terminal 10 (S705), the first server 100 determines whether the frequency of absence of the student is less than a threshold according to the attendance information registered in the third server 300. can be identified (S710).

If the student's absenteeism frequency is less than the critical value (S710 - Y), the first server 100 may determine the student's attendance grade as 1 grade.

In this case, the second server 200 may perform authentication of the guardian's signature (agreement) input through the guardian terminal 20 (S715). In addition, the second server 200 may perform authentication on the teacher's signature (approval) input through the teacher terminal 30 (S720).

Thereafter, when validity verification is performed for each of the guardian's signature and the teacher's signature (S725), the third server 300 may update attendance information according to the attendance record without the signature of the person in charge (S730).

On the other hand, if the student's absenteeism is equal to or greater than the critical value (S710 - N), the first server 100 may determine the student's attendance grade as grade 2.

In this case, the second server 200 may perform authentication not only on the guardian's signature and the teacher's signature, but also on the signature of the person in charge (S735, S740, S745).

In this case, the third server 300 may validate each of the guardian's signature, teacher's signature, and supervisor's signature (S750), and update attendance information as the validation is performed (S730).

As such, the attendance management system according to the present disclosure has the advantage of suppressing frequent absences of students and efficiently distributing administrative tasks according to circumstances by differentiating the payment process according to the student's attendance history.

On the other hand, the attendance management system according to an embodiment of the present disclosure, when the frequency of absences of a student is greater than or equal to a critical value, may determine whether a record of absences for each past date of the corresponding student is falsified.

For example, the first server 100 or the third server 300 inputs the student's absence report by date for a certain period (ex. a certain period before the time the absence report is received) into the artificial intelligence model, The reliability of the stone system can be judged.

If the reliability of at least one absence report output through the artificial intelligence model is less than a critical value, the first server 100 may transmit a warning about the absence report to the teacher terminal 30 and the manager terminal 40 .

The artificial intelligence model may be trained to determine the reliability of the absence records by using, as training data, a plurality of first absence records prepared without false statements and a plurality of second absent records prepared falsely.

This artificial intelligence model can receive each absence system (report type, report reason, details of the report reason, etc.) one by one and determine the reliability of the input absence system.

Alternatively, this artificial intelligence model can receive a plurality of absence reports received within a certain period of time, and determine the reliability of each absence report through the target date, report type, report reason, and details of the report reason for each of the plurality of absence reports. there is. In this case, this artificial intelligence model may be composed of a recurrent neural network (RNN), and the reliability of each absence system may be determined by receiving sequentially received absence systems as input.

That is, information on the absence report previously received for a specific student may be used to determine the reliability of the next absence report. For example, if submission of absence reports due to reasons for appeal, such as a funeral of a relative, is repeated too frequently, this AI model can output the reliability of the repeated absence reports to a lower value gradually.

To this end, this artificial intelligence model can be trained through information on a plurality of absence records (including fake absence records and non-false absence records, respectively) received from each student within a certain period of time.

Meanwhile, in the system according to an embodiment of the present disclosure, in step S220, even if authentication of the guardian's signature fails, additional authentication may be attempted based on a voice call with the guardian.

In relation to this, FIG. 8 is an algorithm for explaining an operation in which a system according to an embodiment of the present disclosure performs step-by-step authentication in relation to a guardian's consent to an absentee system.

Referring to FIG. 8 , the second server 100 may compare the first signature with a registered guardian's signature in order to authenticate the guardian's first signature (S810). Here, if the first signature matches the registered guardian's signature (S820 - Y), the system may identify that authentication of the guardian's consent has been successful and proceed to the teacher's approval step.

On the other hand, if authentication of the first signature fails (S820 - N), such as that the first signature does not match the registered guardian's signature, the second server 200 makes a voice call through the contact information of the guardian's terminal 20. can be performed (S830).

In the voice call, the second server 200 may request the guardian to utter at least one sentence for agreeing to the attendance record (S840).

At this time, when the voice (audio data) spoken from the guardian terminal 20 is received, the second server 200 may perform authentication by comparing the received voice with the pre-stored voice of the guardian (S850). Specifically, it may be determined whether the received voice matches a pre-stored voice.

If authentication through voice is successful (S860 - Y), the second server 200 may identify that the authentication for consent of the guardian has succeeded, and the system may proceed to the teacher's approval step.

As such, if authentication through the input guardian's signature fails but the guardian's consent is confirmed as a result, the second server 200 may update the registered guardian's signature through the guardian's signature that previously failed authentication. there is.

Specifically, the second server 200 may register the guardian's signature that failed authentication as a guardian's signature that can be used for authentication in the future.
