A work management system according to an embodiment of the present invention will be described below with reference to the drawings.
FIG. 1 is a schematic diagram of a work management system according to this embodiment.
As shown in FIG. 1 , the work management system 100 includes a work management terminal 1 and a work management server 2 . A work management terminal 1 and a work management server 2 are connected via a communication network 3 . The communication network 3 is the Internet as an example.

The work management terminal 1 is used by workers. The work management server 2 is managed by a company or the like in which workers are engaged. The work management terminal 1 and the work management server 2 manage working hours of workers.

FIG. 2 is a hardware configuration diagram of the work management terminal and the work management server.
As shown in FIG. 2, the work management terminal 1 includes a CPU (Central Processing Unit) 101, a ROM (Read Only Memory) 102, a RAM (Random Access Memory) 103, a HDD (Solid State Drive) 104, an interface 105, and a communication module 106. Each hardware configuration of is provided as an example.
The work management server 2 similarly includes hardware configurations of a CPU 201, a ROM 202, a RAM 203, an HDD 204, an interface 205, and a communication module 206 as an example.
The interface 105 (205) is, for example, a liquid crystal touch panel or buttons. The work management terminal 1 and the work management server 2 may further include hardware other than the configuration shown in FIG. The work management terminal 1 and the work management server 2 are computers having the hardware configuration described above.

FIG. 3 is a first diagram showing functional blocks of the work management terminal and the work management server.
The CPU 101 of the work management terminal 1 executes terminal programs. As a result, the work management terminal 1 is provided with the functions of a control section 11 , a person authentication section 12 and a work time measurement section 13 . A camera 4, which is an example of a biological information acquisition device, is connected to the work management terminal 1 by a communication cable. The camera 4 may be built in the work management terminal 1 . The camera 4 captures the face of the user who works using the work management terminal 1 and generates a face image.
The CPU 201 of the work management server 2 executes a server program. As a result, the work management server 2 is provided with functional units such as a control unit 21 and a work management unit 22 .

A control unit 11 of the work management terminal 1 shown in FIG. 3 controls each functional unit provided in the work management terminal 1 . The person authentication unit 12 determines whether the user operating the work management terminal 1 is a predetermined user based on the face image (biological information) acquired from the camera 4 . Upon acquiring the face image, the person authentication section 12 generates feature information based on the face image, and transmits an authentication request including the feature information to the work management section 22 of the work management server 2 . When the person authentication unit 12 has not acquired a face image, it outputs a stop of the work time measurement to the work time measurement unit 13 .

Upon receiving authentication permission from the work management section 22 of the work management server 2, the person authentication section 12 instructs the work time measurement section 13 to continue measuring work time. The person authentication unit 12 instructs the work time measurement unit 13 to stop measuring the work time when receiving the authentication disapproval. When the person authentication unit 12 determines that the period during which authentication permission cannot be received from the work management unit 22 of the work management server 2 is equal to or longer than a predetermined period, the control unit 11 cuts off the communication connection with the work management server 2 .

Even if the person authentication unit 12 does not transmit the feature information to the work management server 2, the person authentication unit 12 acquires the feature information of the face image of the person based on the identification information of the work management terminal 1 from the database 20, and uses the feature information. and the feature information of the face image acquired from the camera 4 to determine whether they match. Once the person authentication unit 12 receives the feature information of the face image of the person based on the identification information of its own terminal, the person authentication unit 12 temporarily stores the feature information in the work management terminal 1, Matching may be determined by comparing the feature information of the images.

The work time measurement unit 13 measures the work time based on the time when it is determined that the person corresponding to the biometric information such as the acquired face image is a predetermined person. Note that the work time measurement unit 13 detects whether an input operation is performed using a keyboard or the like, or when the person authentication unit 12 receives authentication permission transmitted by the work management server 2 based on an authentication request including feature information of a face image. Measurement of work time may be started (restarted) when it is detected that

The control unit 21 of the work management server 2 controls each functional unit provided in the work management server 2 . The work management unit 22 acquires information on the user's work time from the work management terminal 1 and manages the user's work time. The work management unit 22 compares the feature information included in the authentication request from the person authentication unit 12 of the work management terminal 1 with the feature information recorded in the database 20 to determine whether they match. The work management unit 22 transmits authentication permission to the object authentication unit 12 of the work management terminal 1 when matching feature information is recorded in the database 20 . If the matching feature information is not recorded in the database 20 , the work management unit 22 transmits authentication disapproval to the object authentication unit 12 of the work management terminal 1 . The work management server 2 may be communicatively connected with the database 20 . The database 20 holds biometric feature information of users who use the work management terminal 1 . The biometric feature information is facial feature information in this embodiment.

FIG. 4 is a diagram showing the processing flow of the work management terminal.
The processing flow of the work management system will be explained step by step below.
When the work management terminal 1 is activated, it executes a terminal program, and the work management terminal 1 is provided with the above functional units. The control unit 11 of the work management terminal 1 instructs the work time measurement unit 13 to start measuring work time. The working time measurement unit 13 starts measuring the working time (step S101). Note that measurement of the working time may be started when it is detected that the user has operated the keyboard. The control unit 11 instructs the person authentication unit 12 to start processing. The person authentication unit 12 determines whether a face image has been obtained from the camera 4 (step S102). When a face image is obtained, the person authentication unit 12 generates feature information based on the face image. The person authentication unit 12 transmits an authentication request including feature information to the work management server 2 (step S103). When the person authentication unit 12 has not acquired the face image, it outputs a stop of the work time measurement to the work time measurement unit 13 . When instructed to stop measuring the working time, the working time measuring unit 13 stops measuring the working time (step S104). If the person authentication unit 12 determines that the period during which authentication permission cannot be received from the work management server 2 is longer than a predetermined period, the control unit 11 may cut off the communication connection with the work management server 2 .

It has been described that the work time measurement unit 13 stops measuring the work time when the person authentication unit 12 does not acquire a face image or receives authentication disapproval from the work management server 2 . However, the work time measurement 13 is not limited to this. measurement may be stopped. Moreover, the face image described above may be obtained from a still image or a moving image.

The work management unit 22 of the work management server 2 compares the feature information included in the authentication request with the feature information recorded in the database 20 to determine whether they match. The work management unit 22 transmits authentication permission to the work management terminal 1 when matching feature information is recorded in the database 20 . If the matching feature information is not recorded in the database 20, the work management unit 22 transmits a non-permission of authentication to the work management terminal 1. FIG. The person authentication unit 12 of the work management terminal 1 can determine whether the user is a predetermined user based on the authentication permission obtained from the work management server 2 in response to the authentication request. That is, the person authentication unit 12 according to this embodiment determines that the user is a predetermined user based on the information obtained from the work management server 2 . Even if the person authentication unit 12 does not transmit the feature information to the work management server 2, the person authentication unit 12 acquires the feature information of the person's face image based on the identification information of the work management terminal 1 from the database 20, and the camera 4 may be compared with the feature information about the face image acquired from the . Note that once the work management terminal 1 receives the feature information of the face image of the person based on the identification information of its own terminal, the feature information may be temporarily stored. By doing so, the work management terminal 1 can omit repeated requests for feature information.

When the person authentication unit 12 receives the authentication permission, the control unit 11 of the work management terminal 1 instructs the work time measurement unit 13 to continue measuring the work time. When the person authentication unit 12 receives the authentication disapproval, the control unit 11 instructs the work time measurement unit 13 to stop measuring the work time. Note that in the above-described processing, after measuring the work time based on the detection of the user's keyboard operation, it is determined whether the user is a predetermined user based on the feature information specified from the face image. However, the work management terminal 1 may start measuring the work time after determining whether the user is a predetermined user based on the feature information specified from the face image.

A person authentication unit 12 acquires a face image from the camera 4 at certain time intervals. The person authentication unit 12 transmits an authentication request to the work management server 2 each time it acquires a face image. The person authentication unit 12 cannot transmit an authentication request when the face image cannot be acquired. In this case, the person authentication unit 12 cannot obtain authentication result information indicating whether authentication is permitted or not permitted from the work management server 2 . The person authentication unit 12 uses the feature information acquired from the database 10 or the feature information temporarily stored in the work management terminal 1 to acquire from the camera 4 without transmitting an authentication request to the work management server 2. The face image thus obtained may be authenticated at predetermined time intervals.

The work time measurement unit 13 determines whether a predetermined time has passed since the user stopped operating the keyboard (step S105). The work time measurement unit 13 detects that the work time measurement has stopped when a predetermined time such as 3 minutes has elapsed since the user's keyboard operation was stopped (step S106). The working time measurement unit 13 determines whether to restart measuring the working time (step S107). The work time measurement unit 13 resumes operation of the keyboard, and when the person authentication unit 12 receives authentication permission from the work management server 2 as a result of an authentication request including feature information based on a face image, the work time measurement is performed. is started (step S108).

Note that the work time measurement unit 13 measures the work time when it detects either that the keyboard operation has been restarted or that the person authentication unit 12 has received authentication permission from the work management server 2 by an authentication request including feature information. Measurement may be started (restarted). Note that the work time measurement unit 13 measures the work time when either the keyboard operation is detected or the face image obtained from the camera 4 is determined to be the desired user. You may do so. For example, when performing an input operation on a keyboard or the like without facing the display where the camera 4 is installed (no face authentication, input operation), or when the face is facing the display where the camera 4 is installed There are cases where no input operation is performed even if the is pointed at (face recognition is performed, no input operation is performed). The working time measuring unit 13 may measure the working time in any of these states. However, the measurement of the work time may be stopped when the input operation is performed without the face authentication, or when the face authentication is performed but the input operation is not performed for a predetermined period of time.

The working time measurement unit 13 counts the working time based on the first instruction to start measuring the working time. This counted value is recorded as the integrated time. When the work time measurement unit 13 receives an instruction to stop measurement of work time from the control unit 11 due to authentication disapproval based on the feature information of the face image, or detects stop of work time measurement based on the stop of keyboard operation, the work time measurement unit 13 detects that the work time measurement has stopped. Temporarily stores the count value of the working time up to and suspends the counting of the working time. In addition, the work time measuring unit 13 receives an instruction to start measuring the work time from the control unit 11 in a state where counting of the work time is temporarily stopped by authentication permission based on the feature information of the face image, or when the keyboard operation is restarted. When the start of time measurement is detected, the counting of work time is restarted. When the working time measurement part 13 resumes counting the working time, it restarts the counting of the working time, adds the restarted count value to the temporarily stored working time, and updates the integrated time.

The person authentication unit 12 outputs timeout information to the control unit 11 when a state in which a face image cannot be obtained continues for a timeout period such as 10 minutes. The working time measurement unit 13 outputs timeout information to the control unit 11 when a state in which keyboard operation cannot be detected continues for a timeout period such as 10 minutes. The control unit 11 determines whether or not the work time measurement process has ended (step S109). When the control unit 11 detects logout, shutdown, or stop of a predetermined work program of the work management terminal 1, or when timeout information is acquired, the control unit 11 determines to end the work time measurement process. In that case, the control unit 11 notifies the work time measuring unit 13 of the end of processing. When the work time measurement unit 13 receives the notification of the end of processing, it transmits information on the work time counted up to now to the work management server 2 (step S110). When the control unit 11 acquires the timeout information, the control unit 11 may stop communication with the work management server 2 after transmitting the work time information to the work management server 2 .

When the work management server 2 receives the work time information, it associates it with the ID of the user who used the work management terminal 1 and records it in the database 20 . Thereby, the user can count the work time using the work management terminal 1 .

In the above-described process, the work time measurement unit 13 temporarily stops counting the work time when authentication permission based on the user's face image cannot be obtained or keyboard operation cannot be detected. Therefore, the working time is counted by excluding the time when the user leaves the work management terminal 1 or when the user is in front of the work management terminal 1 but does not operate the keyboard and does not work from the working time. be able to.

In the above-described process, the work management terminal 1 and the work management server 2 use the face image as biometric information for user authentication, but other biometric information may be used for user authentication. For example, the work management terminal 1 and the work management server 2 may perform authentication using an iris image instead of a face image. Alternatively, if each key of the keyboard is provided with a fingerprint detection function of the user's finger, authentication processing may be performed using fingerprint information instead of the face image or iris image.

In the above process, the person authentication unit 12 may change the interval at which user authentication determination is performed based on biometric information such as a face image. Also, the work time measurement unit 13 may change the interval of the work stop determination by operating the keyboard. For example, when the control unit 11 acquires work time measurement stop from the person authentication unit 12 or the work time measurement unit 13 or when it detects work time measurement start (restart), it acquires the information.

When the control unit 11 receives notifications from both the person authentication unit 12 and the work time measurement unit 13 indicating that the work time measurement start (restart) has been detected a predetermined number of times in succession, the determination interval in each processing unit is set to the third interval. Increase to one interval T1 (first determination period). That is, when face authentication and work continuation can be recognized, the control unit 11 increases the determination interval between the person authentication unit 12 and the work time measurement unit 13 .
Through such processing, when both face authentication based on the feature information of the face image and work continuation based on input operation using a keyboard or the like can be confirmed, the determination interval can be increased. Therefore, since the determination interval is increased, it is possible to reduce the influence of the increased processing load due to the implementation of face authentication on work such as user input operations.

On the other hand, the control unit 11 counts the number of times it receives a notice of work time measurement stop from the person authentication unit 12, and when it receives a work time measurement stop notice a predetermined number of times in succession, the person authentication unit 12 On the other hand, the user is instructed to set the authentication determination interval to a second interval T2 (second determination period) that is shorter than the first interval. Specifically, when the control unit 11 receives a notice of work time measurement stop due to authentication failure based on face authentication for a predetermined number of times in succession, the control unit 11 instructs the person authentication unit 12 to perform authentication determination based on the user's face image. interval to be shortened to the second interval T2. The control unit 11 counts the number of times of receiving a notice of work time measurement stop (non-detection of an input operation of a keyboard or the like) from the work time measurement unit 13, and when the work time measurement stop notice is received consecutively for a predetermined number of times. 2, the work time measurement unit 13 is instructed to set the work stop determination interval to a third interval T3 (second determination period) shorter than the first interval. Specifically, when the control unit 11 receives notification of work time measurement stop for a predetermined number of times consecutively due to no keyboard input operation, the control unit 11 instructs the work time measurement unit 13 to determine the work stop interval. is set short to the third interval T3. Note that when the control unit 11 receives a notification of work stoppage measurement continuously for a predetermined number of times due to no keyboard input operation, the control unit 11 not only sets the work stop determination interval in the work time measurement unit 13, but also The authentication unit 12 may be instructed to set the authentication determination interval based on the user's face image to a short third interval T3.

When the control unit 11 receives notifications of work time measurement stop from both the person authentication unit 12 and the work time measurement unit 13 consecutively a predetermined number of times, the control unit 11 sets the user authentication determination interval to the person authentication unit 12 as the third interval. An instruction is given to set the fourth interval T4, which is shorter than the second interval or the third interval. Further, when the control unit 11 receives notifications of work time measurement stop from both the person authentication unit 12 and the work time measurement unit 13 consecutively a predetermined number of times, the control unit 11 sets the work stop determination interval to the work time measurement unit 13 as follows: Instruct to set the fifth interval, which is shorter than the second interval or the third interval. According to the above-described process, based on an instruction from the control unit 11, the person authentication unit 12 sets the authentication determination interval, or the work time measurement unit 13 sets the work stop determination interval.

In other words, the process of changing the interval for user authentication determination based on the biometric information described above and the process of changing the interval for work stop determination based on keyboard operation can be distinguished as follows.
(1) Permission for authentication by face image, with keyboard operation (2) No permission for authentication by face image (authentication not permitted), with keyboard operation (3) Permission for authentication by face image, no keyboard operation (4) By face image No authentication permission (authentication not permitted), no keyboard operation

In the case of (1) above, the control unit 11 sets the determination interval between the person authentication unit 12 and the work time measurement unit 13 to the first interval T1.
In the case of (2) above, the control unit 11, based on the fact that the number of times of receiving notification of work time measurement stop (unsuccessful authentication) from the person authentication unit 12 has exceeded N2 consecutive times, determines whether the person authentication unit 12 is set to the second interval T2. In the case of (2), since there is a possibility that the user is not working even though the input operation is being performed, the counting of working hours may be stopped, and the user may be logged out or the communication connection may be cut off.

In the case of (3) above, the control unit 11 detects the work based on the fact that the number of times of receiving notification of the work time measurement stop (no input operation detected) from the work time measurement unit 13 consecutively exceeds N3 times. The determination interval in the time measuring unit 13 is set to the third interval T3. In the case of (3), the control unit 11 stops counting the working time, logs out the user, cuts off the communication connection, etc., because there is a possibility that the face is facing the screen but the user is not working. good. In the case of (3) above, the control unit 11 instructs the person authentication unit 12 to perform authentication determination based on the user's face image based on the work time measurement unit 13 stopping continuous work time measurement N3 times or more. The interval may be shortened to a third interval T3. At this time, the control unit 11 sets the interval (third interval T3) for authentication determination based on the face image of the user to be shorter than the interval for authentication determination set in the person authentication unit 12 in case (2). You may do so.

In the case of (4) above, the control unit 11 detects that the number of times that the number of times it has received a notification to stop measuring the working time from the person authentication unit 12 and the number of times that it has received a notification to stop measuring the working time exceed N4. , the determination interval in the person authentication unit 12 and the determination interval in the work time measurement unit 13 are set to the fourth interval T4. It should be noted that the control unit 11 makes the judgment in the person authentication unit 12 based on the fact that the number of times of receiving the notification of work time measurement stop from the person authentication unit 12 and the number of times of receiving the work time measurement stop notification each exceed N4. Instead of shortening the interval and the determination interval in the work time measuring unit 13, the measurement of the work time may be immediately stopped.
If the intervals T1 to T4 are T1>T2>T4 and T1>T3>T4, the sizes of T2 and T3 do not matter. By maximizing the first interval T1, the determination interval between the person authentication unit 12 and the work time measurement unit 13 is lengthened, and the processing load on the work management terminal 1 due to the increased processing load can be reduced. Also, the number of times N2, N3, and N4 indicating the number of times of notification may be N2>N3>N4. Alternatively, N3>N2>N4.

Note that the control unit 11 receives the elapsed time obtained from the person authentication unit 12 indicating that the authentication has not been permitted, and the operation time measurement unit 13 indicating that the keyboard has not been operated. The elapsed time may be acquired, and the determination interval for each processing unit may be determined based on the elapsed time and the threshold.

Another situation in which the counting of working time is stopped and the user is logged out or the communication connection is cut off is, for example, in the case of (2), the number of times of receiving notification of stopping the measurement of working time is more than N2 times in succession. If N2' times are exceeded, in the case of (3), if the number of times that the notification of work time measurement stop has been received consecutively exceeds N3 times, in the case of (4), work time measurement is stopped When the number of times of receiving the notification exceeds N4' times, which is more than N4 times in succession, the number of times of the third judgment period (N2', N3', N4', etc.) (N4'<N2', N3'). The control unit 11 is designed to log out the user or cut off the communication connection when the cumulative number of times of receiving the notification of stopping the measurement of the working time is larger than a predetermined number of times, not the number of times of receiving the notification of stopping the measuring of the working time. good too.

Other situations in which the counting of the working time is stopped and the user is logged out or the communication connection is cut off are, for example, when the logout time has passed L2 in case (2), and when the logout time has elapsed in case (3). A situation in which the third determination period (logout time such as L2, L3, L4, etc.) has passed, such as when the time has passed L3 time, or when the logout time has passed L4 time in the case of (4) Good (L4<L2, L3).

In this way, when face authentication cannot be performed or when it is recognized that the user has stopped working, the timing for determining whether to stop measuring the working time is increased, thereby making it possible to measure the working time more accurately. Further, when face authentication is successful, the work management terminal 1 can set a long interval between authentication requests to the work management server 2, so that the load on the communication network 3 can be reduced.

The person authentication unit 12 may perform biometric authentication of the user using part of the feature information obtained from the biometric information of the user. For example, when the user is wearing a mask, even if the user whose feature information is registered in the database 20 is working, the work management server 2 can store the feature information of the entire face and the feature information recorded in the database 20. match cannot be determined. Therefore, the person authentication unit 12 may transmit to the work management server 2 an authentication request including the feature information of the entire face image or the partial feature information in the vicinity of the eyes. In this case, when the feature information of the entire face image is included in the authentication request, the work management server 2 performs authentication processing using the feature information of the entire face image. Further, when the partial feature information of the face image is included in the authentication request, the work management server 2 performs authentication using the partial feature information. The person authentication unit 12 of the work management terminal 1 or the work management unit of the work management server 2 may determine the transmission timing of the authentication request including the feature information of the entire face image and the transmission timing of the authentication request including the partial feature information. .

More specifically, in the first authentication, the person authentication unit 12 transmits an authentication request based on the feature information of the entire face to the work management server 2, but in subsequent successive authentications, the person can be masked. An authentication request based on partial feature information of a face image may be sent to the work management server 2 . Specifically, at the beginning of work, such as when logging in, it is necessary to remove the mask and perform authentication based on the feature information of the entire face. Authentication may be performed using the partial feature amount of the face image. As a result, at the time of the first login, etc., the mask is removed and the feature amount of the entire face is authenticated, but after that, there is no need to remove the mask each time authentication is performed, thereby improving convenience for the user. After logging out once, it is necessary to remove the mask and perform authentication based on the feature information of the entire face when resuming work and logging in.

This processing determines whether or not the person corresponding to the biometric information is a predetermined person by using all of the biometric information at a predetermined timing during the time when the work is performed. This is one mode of processing for determining whether a person corresponding to biometric information is a predetermined person using part of the information.

FIG. 5 is a second diagram showing functional blocks of the work management terminal and the work management server.
In the above process, the work management terminal 1 measures the work time. However, the work time may be measured by the work management server 2 . In this case, the work management terminal 1 includes a person authentication unit 12 and an operation detection unit 14 as shown in FIG. The operation detection unit 14 detects a user's keyboard operation. When the operation detection unit 14 detects the operation of the keyboard, the operation detection unit 14 transmits to the work management server 2 information indicating the start of work time measurement. Also, the person authentication unit 12 transmits an authentication request to the work management server 2 in the same manner as described above. Then, the work management server 2 similarly performs the work time measurement processing in the work management terminal 1 described above with reference to FIGS. 3 and 4 . However, if the purpose is to reduce the amount of communication in the communication network 3, it is more preferable that the work management terminal 1 performs the work time measurement process.

FIG. 6 is a diagram showing the minimum configuration of the work management system.
The work management terminal 1 and the work management server 2 described above are aspects of the work management device 30 . The work management device 30 may include at least the work time measuring section 300 . The work time measurement unit 300 measures work time based on the time when it is determined that the person corresponding to the acquired biometric information is a predetermined person.

According to the above-described work management system, face authentication is performed based on the characteristic information of the face image based on the instruction to start measuring the work time by the input operation of the keyboard or the like, and both or at least one of the success of the face authentication and the keyboard operation is performed. counts the accumulated work time when the Also, if the face recognition fails or the keyboard is not operated for a period of time, the counting of the accumulated work time is stopped. In addition, the work management system includes (1) a state in which authentication by face image is permitted and a keyboard is operated, (2) a state in which authentication by a face image is not permitted (authentication is not permitted), and a state where keyboard operation is performed, and (3) authentication by a face image. Authentication by the person authentication unit 12 according to the states (1) to (4) such as permission, no keyboard operation, (4) face image authentication not permitted (authentication not permitted), no keyboard operation, etc. The determination interval and the work stop determination interval in the work time measurement unit 13 are changed.
