[0018] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A terminal device, an information processing system, a control method for a terminal device, and a control program for a terminal device according to an embodiment of the present invention will be described in detail below with reference to the drawings.

[0019] First, functions of the information processing system will be described with reference to Fig. 1. Fig. 1 is a block diagram showing an example of the software configuration of the information processing system in the embodiment.

[0020] In FIG. 1, an information processing system 100 includes a measuring device 1, a terminal device 2, a face authentication device 3, and a management device 4. The measuring device 1 and the terminal device 2 are connected via wireless communication. The wireless communication connecting the measuring device 1 and the terminal device 2 is communication using a communication method standardized in a short-range wireless communication standard. For example, Bluetooth (registered trademark) can be used as the communication method for the wireless communication. For example, Bluetooth Low Energy (BLE), which is an extension of the Bluetooth specification, can be used as the communication method for the wireless communication. In the following description, a case where the BLE communication method is used for wireless communication will be described as an example.

[0021] The terminal device 2 is a terminal used by a user, and is, for example, a mobile phone, a smartphone, a tablet PC, etc. The terminal device 2 is connected to a network 9 by network communication such as mobile communication.

[0022] The terminal device 2, the face authentication device 3, and the management device 4 are connected to each other via a network 9 so as to be able to communicate with each other.

[0023] The network 9 is not limited to a communication method. The network 9 is, for example, the Internet. The network 9 may include wired communication or wireless communication in part of the communication path. For example, the network 9 may include a base station for mobile communication, an access point for wireless LAN, etc.

[0024] 1 illustrates an example of the configuration of the information processing system 100, and does not limit the configuration of the information processing system 100. For example, the information processing system 100 may include a plurality of any of the measuring devices 1, the terminal devices 2, the face authentication devices 3, and the management devices 4.

[0025] The measuring device 1 has the functional units of a communication control unit 11, a pressure measurement unit 12, a concentration measurement unit 13, a storage unit 14, and a device information display unit 15. The terminal device 2 has the functional units of a wireless communication unit 211, a data acquisition unit 212, a network communication unit 213, a data provision unit 214, a camera control unit 22, an authentication processing unit 23, a confirmation unit 24, a recording unit 25, and an auxiliary information acquisition unit 26. Each of the above functional units in the information processing system 100 in this embodiment will be described as a functional module realized by a program (software).

[0026] The communication control unit 11 controls wireless communication with the terminal device 2. The communication control unit 11 outputs a wireless signal for making the terminal device 2 recognize the presence of the measurement device 1. The communication control unit 11 outputs a wireless signal from the communication control unit 11 in one-way communication (broadcast type communication) at a predetermined time interval. When the wireless signal output from the communication control unit 11 is detected by the terminal device 2, the wireless communication unit 211 of the terminal device 2 transmits a response signal in response to the wireless signal. The response signal notifies the measurement device 1 that a wireless communication connection has been established. When the communication control unit 11 receives the response signal and is notified that wireless communication has been established, the communication control unit 11 ends the wireless communication. When the wireless communication connection is disconnected, the communication control unit 11 may perform wireless communication again to automatically restore wireless communication with the terminal device 2. When the communication control unit 11 ends the wireless communication, it may transmit a signal to disconnect the connection to the terminal device 2.

[0027] The pressure measurement unit 12 measures the pressure of the breath blown by the subject detected by the pressure sensor 121, and detects whether the pressure reaches a predetermined pressure. For example, if the subject intentionally blows less breath, the alcohol concentration contained in the breath may not be measured correctly. If the breath pressure measured by the pressure measurement unit 12 does not reach the predetermined pressure, the alcohol concentration is not measured, thereby preventing an incorrect measurement of the alcohol concentration. When the pressure measurement unit 12 detects that the breath pressure has reached the predetermined pressure, the pressure measurement unit 12 may notify the subject that the breath is being blown correctly by a chime sound or the like. Furthermore, when the pressure measurement unit 12 detects that the breath pressure has not reached the predetermined pressure within a predetermined time, the pressure measurement unit 12 may notify the subject that the breath is not being blown sufficiently by an alarm sound or the like.

[0028] The concentration measurement unit 13 measures the alcohol concentration (hereinafter sometimes referred to as the "measurement result") contained in the breath detected by the concentration sensor 131. The measurement result may be a measured value (numerical value) of the alcohol concentration, a graded evaluation according to the alcohol concentration (e.g., A to D), or a judgment result as to whether or not the concentration is equal to or higher than a predetermined concentration. The concentration sensor 131 selectively detects an alcohol component from various components contained in the breath. For example, an electrochemical gas sensor may be used as the concentration sensor 131. The concentration measurement unit 13 may be configured to notify the subject by an alarm sound or the like when the measured value is higher than a preset alcohol concentration.

[0029] The concentration measurement unit 13 measures the alcohol concentration when the pressure measurement unit 12 detects that the breath pressure has reached a predetermined pressure. For example, the concentration measurement unit 13 measures the alcohol concentration at the moment when the pressure reaches the predetermined pressure. The concentration measurement unit 13 may measure the alcohol concentration when a predetermined time has elapsed since the pressure reaches the predetermined pressure. The concentration measurement unit 13 may also measure the average alcohol concentration during the time when the pressure is equal to or higher than the predetermined pressure.

[0030] The communication control unit 11 outputs the measurement results and the device information stored in the storage unit 14 to the terminal device 2. By acquiring the measurement results and the device information via the communication control unit 11, the terminal device 2 becomes able to recognize from which measuring device the acquired measurement results were output.

[0031] The communication control unit 11 outputs control information to the terminal device 2 when the pressure measurement unit 12 detects that the breath pressure has reached a predetermined pressure. The control information is information for controlling the timing of photographing by the camera 221 in the terminal device 2. The timing for outputting the control information from the communication control unit 11 is after the breath pressure has reached a predetermined pressure in the pressure measurement unit 12. For example, the communication control unit 11 can output the control information when the pressure has reached a predetermined pressure. The communication control unit 11 may also output the control information when the pressure has continued for a predetermined period of time at or above a predetermined pressure. The concentration measurement unit 13 may also output the control information when the measurement of the alcohol concentration in the concentration measurement unit 13 is completed.

[0032] The storage unit 14 stores device information for identifying the measurement device 1. The device information is information for identifying the measurement device 1, such as a serial number. The device information stored in the storage unit 14 may be protected so that it cannot be easily rewritten by a user of the measurement device 1 (e.g., a subject). The device information stored in the storage unit 14 can be protected, for example, by storing the device information in a secure area of ​​the storage unit 14. The device information stored in the storage unit 14 can also be protected by restricting the use of a program that rewrites the device information by a password or the like. By protecting the device information stored in the storage unit 14, it is possible to ensure that the measurement device can be identified from other measurement devices.

[0033] The storage unit 14 may store a setting for the transmission power of the wireless signal, a setting for whether or not to automatically execute wireless communication when the power is turned on, etc. The information stored in the storage unit 14 may be stored, for example, when the measurement device 1 is shipped from the factory.

[0034] The device information display unit 15 displays the device information at a position where an image can be captured by the camera 221 of the terminal device 2. The position where an image can be captured by the camera 221 is a position where an image can be captured by the camera 221 at least while the subject is blowing breath into the measuring device 1, and is, for example, the surface of the measuring device 1. The device information displayed by the device information display unit 15 is, for example, visible light or infrared light emitted from the surface of the measuring device 1, and may be expressed by flashing light.

[0035] Furthermore, the device information display unit 15 may be a sticker on which a two-dimensional code including device information is printed. The sticker may be a sticker on which the two-dimensional code becomes unreadable once removed in order to prevent replacement. In this embodiment, the device information display unit 15 is described as a two-dimensional code sticker attached to the surface of the measuring device 1.

[0036] The wireless communication unit 211 controls wireless communication with the measurement device 1. The wireless communication unit 211 detects a wireless signal output from the measurement device 1 and executes wireless communication to output a response signal in response to the detected wireless signal to the terminal device. When the wireless communication unit 211 detects wireless signals from multiple measurement devices 1, it specifies one of the measurement devices 1 to be connected to and outputs a response signal. In other words, the wireless communication unit 211 establishes wireless communication with one measurement device 1. The wireless communication unit 211 enables reception of data from the measurement device 1 with which wireless communication has been established.

[0037] The data acquiring unit 212 acquires data from the measuring device 1 with which wireless communication has been established by the wireless communicating unit 211. For example, the data acquiring unit 212 acquires the measurement result and the device information stored in the storage unit 14 from the measuring device 1. The data acquiring unit 212 may also acquire control information output from the measuring device 1.

[0038] The network communication unit 213 controls communication with the face authentication device 3 and the management device 4 via the network 9. For example, the network communication unit 213 controls communication in a mobile network, a wireless LAN, or the like.

[0039] The data providing unit 214 provides the measurement results acquired by the data acquiring unit 212 and the facial photograph of the subject taken by the camera 221 to the management device 4 that is communicatively connected via the network 9 .

[0040] The camera control unit 22 controls the camera 221 based on the control information output from the measuring device 1 and acquired by the wireless communication unit 211 when a preset pressure is detected by the pressure measurement unit 12. This allows the camera 221 to capture an image of the subject blowing breath into the measuring device 1. For example, the camera control unit 22 operates the camera 221 to acquire a still image when the control information is acquired. The camera control unit 22 may also operate the camera 221 to acquire a video when the control information is acquired.

[0041] For example, the camera 221 is a front camera arranged on the same surface as the display unit of the terminal device 2. In this case, the subject can check his / her own image taken by the camera 221 on a display unit (not shown) of the terminal device 2. The subject can adjust the photographing position while checking the display unit of the terminal device 2 so that the device information displayed by the device information display unit 15 of the measuring device 1 and his / her own face are photographed by the camera 221. In this state, the subject blows breath into the measuring device 1, and the camera 221 can simultaneously photograph the subject's face and the device information when the subject is blowing breath. That is, the photographed image taken by the camera 221 includes the subject's face and the device information when the subject is blowing breath.

[0042] The camera control unit 22 may control shooting in the camera 221 when a face is detected in the captured image. For example, the camera control unit 22 detects the subject's face from the captured image captured by the camera 221, and records the captured image as a still image when a face is detected. The camera control unit 22 may also start recording the captured image as a moving image when a face is detected.

[0043] The camera control unit 22 may also perform image processing on the captured image and record it. For example, the camera control unit 22 may trim the captured image based on the position of the detected face. Note that the captured image recorded by the camera control unit 22 may include an image that has been subjected to image processing.

[0044] The authentication processing unit 23 transmits the photographed image taken by the camera 221 to the face authentication device 3. The face authentication device 3 is a device that authenticates the identity of a person based on a face photo. The face authentication device 3 is, for example, a service server that provides a Web service of a face authentication service. For example, a face photo of the subject is registered in advance in the face authentication device 3. A plurality of face photos of the subject taken from different angles may be registered in the face authentication device 3. The face authentication device 3 extracts feature amounts of the pre-registered face photo and the photographed image transmitted from the authentication processing unit 23, and compares the feature amounts. The face authentication device 3 can authenticate whether the subject included in the photographed image transmitted from the authentication processing unit 23 is the person in the pre-registered face photo (authentication OK) or a different person (authentication NG) depending on whether the feature amounts are similar to each other. The face authentication device 3 may transmit the authentication result to the authentication processing unit 23 and the management device 4.

[0045] Furthermore, the authentication processing unit 23 may acquire the authentication result transmitted from the face authentication device 3. The authentication processing unit 23 may display the acquired authentication result on a display device (not shown) of the terminal device 2. When the acquired authentication result is NG, the authentication processing unit 23 may notify the authentication result from a display unit or speaker (not shown) of the terminal device 2.

[0046] Furthermore, the authentication processing unit 23 may transmit the captured image that has been subjected to image processing in the camera control unit 22 to the face authentication device 3. For example, the authentication processing unit 23 may transmit the captured image in which the subject's face has been detected and cropped in the camera control unit 22 to the face authentication device 3. By transmitting the cropped captured image, the authentication processing unit 23 can reduce the transmission capacity.

[0047] The confirmation unit 24 confirms whether the device information acquired from the measuring device 1 by the wireless communication unit 211 matches the device information displayed on the device information display unit 15 and captured by the camera 221. The confirmation unit 24, for example, decodes a two-dimensional code included in the captured image to acquire the device information included in the two-dimensional code. By confirming that the device information acquired together with the alcohol concentration measurement result matches the device information captured by the camera 221, the confirmation unit 24 can confirm that the alcohol concentration measurement result is the result measured by the measuring device 1 captured by the camera 221.

[0048] By checking whether the device information matches in the confirmation unit 24, it is possible to prevent fraudulent conduct such as, for example, a sober collaborator blowing into the measuring device 1 near a subject who is blowing into a device different from the measuring device 1, thereby avoiding alcohol testing.

[0049] When the confirmation unit 24 confirms that the device information matches, the recording unit 25 records the measurement result of the alcohol concentration measured when a preset pressure is detected in the pressure measurement unit 12. By recording the measurement result when the confirmation unit 24 confirms that the device information matches, the recording unit 25 can prevent measurement results measured by other measurement devices from being recorded, thereby making it possible to prevent fraud in alcohol concentration measurements.

[0050] Furthermore, the recording unit 25 may record the image captured by the camera 221 together with the measurement results. By recording the image captured together with the measurement results, it becomes possible to easily grasp the correspondence between the subject and the measurement results when checking the measurement results on the terminal device 2.

[0051] The incidental information acquisition unit 26 acquires incidental information that can be acquired by the terminal device 2. The incidental information that can be acquired by the terminal device 2 is, for example, location information (geotag) of the terminal device 2 at the time of shooting by the camera 221, time, shooting conditions of the camera 221, etc. The recording unit 25 may record the incidental information acquired by the incidental information acquisition unit 26 together with the captured image or the measurement result. The data providing unit 214 may transmit the incidental information acquired by the incidental information acquisition unit 26 to the management device 4.

[0052] For example, the location information acquired by the incidental information acquisition unit 26 can be used as information to prove the location where the alcohol concentration measurement was performed. In the information processing system 100, the subject can carry the measuring device 1 and the terminal device 2, so that the alcohol concentration measurement can be performed at any location. For example, assume that the car driven by the subject is parked in a designated parking lot, and the subject is required to measure the alcohol concentration immediately before driving. By comparing the previously known location information of the parking lot with the location information at the time of shooting acquired by the incidental information acquisition unit 26, it can be proved that the alcohol concentration measurement was performed at an appropriate location. Similarly, the time information acquired by the incidental information acquisition unit 26 makes it possible to prove the time when the concentration measurement was performed.

[0053] The management device 4 is a device that manages the alcohol test performed by the subject. The management device 4 records the measurement results and the photographed images of the subject obtained from the data providing unit 214. For example, the management device 4 can create a test history for each subject by recording the measurement results and the photographed images of the subject for each subject. In addition, the management device 4 can manage the working status of the subject by recording the work record, the measurement results, and the photographed images for each subject. For example, if the subject is a truck driver, it is possible to manage the driver's fatigue state, etc. by recording the working hours, mileage, loading status, etc. together with the measurement results and photographed images as a work record.

[0054] Note that the above-mentioned functional units possessed by the measurement device 1 or the terminal device 2 are merely examples of functions, and do not limit the functions possessed by the measurement device 1 or the terminal device 2. For example, the measurement device 1 or the terminal device 2 does not need to have all of the functional units described above, and may have only some of the functional units. Furthermore, the measurement device 1 or the terminal device 2 may have functions other than those described above.

[0055] As described above, the above-mentioned functional units of the measuring device 1 or the terminal device 2 are described as being realized by software. However, at least one or more of the above-mentioned functional units of the measuring device 1 or the terminal device 2 may be realized by hardware.

[0056] Furthermore, any of the above-mentioned functional units possessed by the measurement device 1 or the terminal device 2 may be implemented by dividing one functional unit into a plurality of functional units. Furthermore, any two or more of the above-mentioned functional units possessed by the measurement device 1 or the terminal device 2 may be implemented by integrating them into one functional unit. Fig. 1 shows the functions possessed by the measurement device 1 or the terminal device 2 as functional blocks, and does not, for example, indicate that each functional unit is configured by a separate program file or the like.

[0057] Furthermore, the measuring device 1 or the terminal device 2 may be a device realized by one housing, or a system realized by multiple devices connected via a network or the like. For example, the measuring device 1 or the terminal device 2 may have some or all of its functions realized by another virtual device, such as a cloud service provided by a cloud computing system. In other words, the measuring device 1 or the terminal device 2 may have at least one or more of the above-mentioned functional units realized by another device.

[0058] Next, the external appearance of the measurement device 1 will be described with reference to Fig. 2. Fig. 2 is a diagram showing an example of the external appearance of a measurement device in an embodiment. In the following description, Fig. 1 will be referred to as appropriate.

[0059] In FIG. 2, the measurement device 1 has an air inlet 161, a two-dimensional code 162, a power button 163, a measurement value display unit 164, and a history display button 165.

[0060] For example, the subject inserts a straw into blowing port 161 and blows breath through the inserted straw. The pressure of the breath blown into blowing port 161 is measured by pressure sensor 121 described in FIG. 1, and the alcohol concentration is measured by concentration sensor 131.

[0061] The two-dimensional code 162 is an example of the device information display unit 15 in Fig. 1, and includes device information. The two-dimensional code 162 is affixed, for example, to the left side surface of the measuring device 1 as shown in the figure. The two-dimensional code 162 may be affixed to any position, such as the front or top surface of the measuring device 1. The two-dimensional code may also be affixed to multiple locations on the measuring device 1. The two-dimensional code is affixed to a position where the face of the subject 5 can be photographed by the camera 221 at the same time when the subject 5 blows into the measuring device 1, as described in Fig. 3.

[0062] The power button 163 is a button for turning on / off the power of the measurement device 1. Pressing the power button 163 displays a measurement value display section 164. The measurement value display section 164 is a display section that displays the measured alcohol concentration. Pressing the power button 163 also starts periodic output of a wireless signal (not shown).

[0063] The history display button 165 is a button for reading out the history of alcohol concentration measurements taken in the past. By pressing the history display button 165, the measurement value history is displayed on the measurement value display section 164.

[0064] Next, a method for measuring an alcohol concentration will be described with reference to Fig. 3. Fig. 3 is a diagram showing an example of a method for measuring an alcohol concentration in an embodiment.

[0065] In FIG. 3, the subject 5 holds the measuring device 1 in his left hand and the terminal device 2 in his right hand. A straw 166 is inserted into the blowing port 161 of the measuring device 1. The subject 5 starts a terminal device control program (application program) (not shown) installed in the terminal device 2. When the terminal device control program is started, an image captured by the camera 221 is displayed on the display unit 222. While viewing the display unit 222 of the terminal device 2, the subject 5 adjusts the photographing position and direction of the terminal device 2 so that his face and the two-dimensional code 162 are displayed on the display unit 222. While checking that his face and the two-dimensional code 162 are displayed on the display unit 222, the subject 5 blows his breath into the straw 166 to measure the alcohol concentration. When a preset pressure is detected in the pressure measuring unit 12 of FIG. 1, an image captured by the camera 221 is recorded and displayed on the display unit 222. The measurement result measured by the measuring device 1 is acquired by the terminal device 2 by wireless communication together with the device information stored in the storage unit 14. The display unit 222 may display the acquired measurement results together with the captured image.

[0066] Next, the operation of the measurement device 1 will be described with reference to Fig. 4. Fig. 4 is a flowchart showing an example of the operation of the measurement device in the embodiment. The operations in the flowchart shown below will be described as being performed by the measurement device 1, but each operation can be performed by each functional unit of the measurement device 1 described above.

[0067] 4, the measurement device 1 determines whether or not the power button is turned on (step S11). If it is determined that the power button is not turned on (step S11: NO), the measurement device 1 repeats the process of step S11 and waits for the power button to be turned on.

[0068] If it is determined that the power button has been turned on (step S11: YES), the measurement device 1 starts outputting a wireless signal (step S12).

[0069] After executing the process of step S12, the measurement device 1 determines whether or not a response signal has been received (step S13). If it determines that a response signal has not been received (step S13: NO), the measurement device 1 determines whether or not the power button has been turned off (step S14). If it determines that the power button has not been turned off (step S14: NO), the measurement device 1 repeats the processes of steps S13 to S14 and waits for the power button to be operated.

[0070] If it is determined that the response signal has been received (step S13: YES), the measurement device 1 starts up the concentration sensor (step S15). Note that, although the present embodiment has shown a case in which the use conditions of the concentration sensor are limited to after wireless communication has been established, the concentration sensor may be started up by turning on the power button.

[0071] After executing the process of step S15, the measurement device 1 judges whether or not the breath pressure has reached a preset pressure (step S16). If it is judged that the breath pressure has not reached the preset pressure (step S16: NO), the measurement device 1 skips the processes of steps S17 to S20 and waits until the breath pressure reaches the preset pressure. On the other hand, if it is judged that the breath pressure has reached the preset pressure (step S16: YES), the measurement device 1 starts measuring the alcohol concentration (step S17).

[0072] After executing the process of step S17, the measurement device 1 determines whether the measurement has ended (step S18). Whether the measurement has ended can be determined, for example, by whether the breath pressure has continued for a predetermined time or more. If it is determined that the measurement has not ended (step S18: NO), the measurement device 1 repeats the processes of steps S16 to S18 and waits for the measurement to end in a state where the breath pressure is maintained at or above a preset pressure.

[0073] On the other hand, if it is determined that the measurement has ended (step S18: YES), the measurement device 1 outputs the measurement result to the terminal device 2 (step S19), and outputs control information (step S20).

[0074] After executing the process of step S20, or if it is determined that the breath pressure has not reached a preset pressure (step S16: NO), the measurement device 1 determines whether or not to end the measurement (step S21). Whether or not to end the measurement can be determined, for example, when the breath pressure has not reached a predetermined pressure for a predetermined period of time or more, or when it is determined that all measurements in the measurement device 1 have been completed. When it is determined not to end the measurement (step S21: NO), the measurement device 1 repeatedly executes the processes of steps S16 to S20.

[0075] On the other hand, if it is determined that the measurement is to be ended (step S21: YES), or if it is determined in the process of step S14 that the power button has been turned off (step S14: NO), the measurement device 1 ends the output of the wireless signal (step S22). After executing the process of step S22, the measurement device 1 ends the operation of the illustrated flowchart.

[0076] Next, the operation of the terminal device 2 will be described with reference to Fig. 5. Fig. 5 is a flowchart showing an example of the operation of the terminal device 2 in the embodiment. The operation of the flowchart described in Fig. 5 is started by starting an application program (sometimes abbreviated as "app") that controls the terminal device 2 and is installed in the terminal device 2. The operations in the flowchart shown below will be described as being executed by the terminal device 2, but each operation can be executed by each functional unit of the terminal device 2 described above.

[0077] 5, the terminal device 2 activates the camera 221 (step S31). By activating the camera 221, a captured image is displayed on the display unit 222.

[0078] After executing the process of step S31, the terminal device 2 judges whether or not it has detected a wireless signal output from the measurement device 1 (step S32). If it is judged that a wireless signal has not been detected (step S32: NO), the terminal device 2 repeats the process of step S32 and waits for detection of a wireless signal.

[0079] On the other hand, if it is determined that a wireless signal has been detected (step S32: YES), the terminal device 2 outputs a response signal in response to the wireless signal to the measurement device 1 (step S33).

[0080] After executing the process of step S33, the terminal device 2 judges whether or not the measurement result has been acquired from the measurement device 1 (step S34). If it is judged that the measurement result has not been acquired (step S34: NO), the terminal device 2 repeats the process of step S34 and waits for acquisition of the measurement result. On the other hand, if it is judged that the measurement result has been acquired (step S34: YES), the terminal device 2 temporarily stores the measurement result (step S35). The measurement result may be temporarily stored in the recording unit 25, for example.

[0081] After executing the process of step S35, the terminal device 2 determines whether or not control information has been acquired from the measurement device 1 (step S36). If it is determined that the control information has not been acquired (step S36: NO), the terminal device 2 repeats the process of step S36 and waits for acquisition of the control information. On the other hand, if it is determined that the control information has been acquired (step S36: YES), the terminal device 2 acquires a captured image from the camera 221 (step S37) and records the captured image (step S38).

[0082] After executing the process of step S38, the terminal device 2 executes image processing on the captured image (step S39). The image processing includes, for example, cropping, color correction, brightness correction, or resolution correction of the captured image. After executing the process of step S39, the terminal device 2 transmits image data of the captured image to the face authentication device 3 (step S40).

[0083] After executing the process of step S40, the terminal device 2 judges whether or not the device information matches in the confirmation by the confirmation unit 24 (step S41). If it is judged that the device information does not match (step S41: NO), the terminal device 2 notifies the confirmation result (mismatch of device information, etc.). The notification of the confirmation result can be executed by, for example, displaying the confirmation result on the display unit 222.

[0084] On the other hand, if it is determined that the device information matches (step S41: YES), the terminal device 2 determines whether or not the personal authentication is OK (step S43). Whether or not the personal authentication is OK can be determined, for example, by acquiring the authentication result from the face authentication device 3. If it is determined that the personal authentication is not OK (step S43: NO), the terminal device 2 notifies the authentication result (personal authentication NG). The notification of the authentication result can be executed, for example, by displaying the confirmation result on the display unit 222.

[0085] On the other hand, if it is determined that the personal authentication is OK (step S43: YES), the terminal device 2 records the measurement result (step S45) and provides the recorded measurement result to the management device 4 (step S46). After executing the process of step S42, the process of step S44, or the process of step S46, the terminal device 2 ends the operation shown in the flowchart.

[0086] Next, another operation of the terminal device 2 will be described with reference to Fig. 6. Fig. 6 is a flowchart showing another example of the operation of the terminal device 2 in the embodiment.

[0087] In Fig. 6, when the application is started, the terminal device 2 displays an input screen for inputting the roll call category and instructs the subject to input the roll call category (step S51). The roll call category is a category of roll call work in a job, and is categorized according to the timing of, for example, when arriving at work, during work, or when leaving work. The roll call category may include, for example, an "attendance roll call" conducted when arriving at work, an "intermediate roll call" conducted during work, or a "leave roll call" conducted when leaving work. The terminal device 2 may display a selection button for selecting one of the roll call categories so that the subject can operate the selection button.

[0088] After executing the process of step S51, the terminal device 2 judges whether the selection of the roll call category is completed (step S52). If it is judged that the selection of the roll call category is not completed (step S52: NO), the terminal device 2 repeats the process of step S52 and waits for the selection of the roll call category to be completed.

[0089] On the other hand, when it is determined that the selection of the roll call category is completed (step S52: YES), the terminal device 2 activates the camera 221 to start capturing an image (step S53). By activating the camera 221, a captured image is displayed on the display unit 222.

[0090] After executing the process of step S53, the terminal device 2 judges whether the device authentication has been successful or not (step S54). Whether the device authentication has been successful or not can be determined in the same manner as the processes of steps S36 to S41 described in FIG. 5. That is, the terminal device 2 can determine that the device authentication has been successful by acquiring device information from the measurement device 1 and judging whether it matches the photographed device information. If it is determined that the device authentication has not been successful (step S54: NO), the terminal device 2 returns to the process of step S51 and waits again for the selection of the roll call category to be completed.

[0091] On the other hand, if it is determined that the device authentication has been successful (step S54: YES), the terminal device 2 displays a screen instructing the subject to power on the measuring device 1 (step S55).

[0092] After executing the process of step S55, the terminal device 2 establishes wireless communication with the measurement device 1 (step S56). The wireless communication connection can be executed in the same manner as the processes of steps S32 to S33 described with reference to FIG.

[0093] After executing the process of step S56, the terminal device 2 judges whether the personal authentication has been successful (step S57). The judgment of whether the personal authentication has been successful can be executed in the same manner as the process of steps S37 to S40 and step S43 described in FIG. 5. The terminal device 2 may display the name of the authenticated subject, and judge the personal authentication to be successful when the subject confirms it. If it is judged that the personal authentication has not been successful (step S57: NO), the terminal device 2 repeats the process of step S57 and waits for the personal authentication to be successful. Note that the personal authentication process in the process of step S57 may be terminated, for example, when a predetermined number of failures have occurred, and the operation shown in the flowchart may be terminated. The failure of the personal authentication may be notified to the management device 4.

[0094] On the other hand, when it is determined that the personal authentication has been successful (step S57: YES), the terminal device 2 displays an input screen for self-diagnosis so that the subject can input the result of the self-diagnosis. The self-diagnosis is the subject's own condition reported by the subject himself, and includes, for example, report items such as whether or not he has an injury, whether or not he feels sleepy, whether or not he is in good health, whether or not he has taken medicine, whether or not he has drunk alcohol, etc. If the result of the self-diagnosis in any of the report items is bad, the terminal device 2 may notify the management device 4 of the diagnosis result and end the operation shown in the flowchart.

[0095] After executing the process of step S58, the terminal device 2 displays a screen instructing the subject to start measurement on the measurement device 1, and prompts the subject to start measurement (step S59).

[0096] After executing the process of step S59, the terminal device 2 starts up the camera 221 to start capturing images, and judges whether or not the personal authentication has been successful based on the captured image of the person (step S60). By performing personal authentication before starting measurement in the measurement device 1, it is possible to prevent impersonation in which the subject is replaced. If it is judged that the personal authentication has not been successful (step S60: NO), the terminal device 2 notifies the management device 4 of the failure of the personal authentication, and ends the operation shown in the flowchart.

[0097] On the other hand, if it is determined that the personal authentication has been successful (step S60: YES), the terminal device 2 determines whether or not measurement has started (step S61). Whether or not measurement has started can be determined, for example, by whether or not the pressure measured by the pressure measurement unit 12 has reached a preset pressure. If the pressure measured by the pressure measurement unit 12 has been preset, it can be determined that the measurement in the measurement device 1 is in the middle of measurement (being measured). If it is determined that measurement has not started (step S61: NO), the terminal device 2 repeats the process of step S61 and waits for measurement to start.

[0098] On the other hand, if it is determined that the measurement has started (step S61: YES), the terminal device 2 determines whether or not the personal authentication has been successful (step S62). By performing personal authentication during the measurement in the measurement device 1, it is possible to prevent impersonation, in which the subject is replaced in the middle of the measurement. If it is determined that the personal authentication has not been successful (step S62: NO), the terminal device 2 notifies the management device 4 of the failure of the personal authentication and ends the operation shown in the flowchart.

[0099] On the other hand, if it is determined that the personal authentication has been successful (step S62: YES), the terminal device 2 determines whether or not the measurement has been completed (step S63). Whether or not the measurement has been completed can be determined, for example, by whether or not a measurement result has been obtained from the measurement device 1. If it is determined that the measurement has not been completed (step S63: NO), the terminal device 2 repeats the process of step S63 and waits for the measurement to be completed.

[0100] On the other hand, if it is determined that the measurement has ended (step S63: YES), the terminal device 2 determines whether or not the personal authentication has been successful (step S64). By performing personal authentication at the end of the measurement in the measurement device 1, it is possible to further prevent impersonation, in which the subject is replaced during the measurement. If it is determined that the personal authentication has not been successful (step S64: NO), the terminal device 2 notifies the management device 4 of the failure of the personal authentication and ends the operation shown in the flowchart.

[0101] In the operation shown in FIG. 6, the effect of preventing spoofing can be improved by performing the personal authentication multiple times. The timing and number of times of performing the personal authentication may be arbitrarily selected. The timing and number of times of performing the personal authentication may vary depending on the purpose of using the terminal device or the request of the user, and flexible operation of the personal authentication can be achieved by arbitrarily setting the timing and number of times of performing the personal authentication. For example, it may be possible to set only one of the personal authentications in step S57, step S60, step S62, or step S64 to be performed. It may also be possible to set two of the personal authentications in step S57, step S60, step S62, or step S64 to be performed.

[0102] Furthermore, the personal authentication in steps S60, S62, and S64 may be performed without the subject's knowledge. If the subject knew the timing of the personal authentication, there was a possibility that a method of evading the authentication would be considered. By performing the personal authentication at a timing that the subject does not notice, it is possible to prevent intentional evasion of authentication.

[0103] On the other hand, if it is determined that the personal authentication has been successful (step S64: YES), the terminal device 2 records the measurement result (step S65), transmits the measurement result (step S66), and ends the operation shown in the flowchart. The process of recording the measurement result in step S65 can be executed in the same process as step S45. Moreover, the process of transmitting the measurement result in step S66 can be executed in the same process as step S46.

[0104] It should be noted that the illustrated flowchart shows an example of the operation in this embodiment, and does not limit the operation of the measurement device 1 or the terminal device 2.

[0105] 6, for example, when it is determined that the device authentication is not successful (step S54: NO), the process returns to step S51 and waits again for the selection of the roll call category to be completed. However, when it is determined that the device authentication is not successful (step S54: NO), the process may wait for a certain period of time (for example, 2 minutes) to elapse, and then display a screen indicating that the system is interrupted, and after the OK button is pressed, the process may return to step S51.

[0106] Also, when it is determined that the personal authentication is not successful (step S57: NO), the process of step S57 is repeated and the operation of waiting for the personal authentication to be successful is exemplified. However, when it is determined that the personal authentication is not successful (step S57: NO), it may wait for a certain period of time to pass, and then display a screen indicating that the system is interrupted, and return to the process of step S51 after the OK button is pressed.

[0107] The above-mentioned various processes of the present embodiment may be performed by recording a program for realizing the functions constituting the device described in the present embodiment in a computer-readable recording medium, and reading and executing the program recorded in the recording medium into a computer system. The "computer system" referred to here may include hardware such as an OS and peripheral devices. In addition, if a WWW system is used, the "computer system" also includes a homepage providing environment (or display environment). In addition, the "computer-readable recording medium" refers to a storage device such as a flexible disk, a magneto-optical disk, a ROM, a writable non-volatile memory such as a flash memory, a portable medium such as a CD-ROM, or a hard disk built into a computer system.

[0108] Furthermore, the term "computer-readable recording medium" includes a memory that holds a program for a certain period of time, such as a volatile memory (e.g., DRAM (Dynamic Random Access Memory)) inside a computer system that becomes a server or a client when a program is transmitted via a network such as the Internet or a communication line such as a telephone line. The above-mentioned program may be transmitted from a computer system that stores the program in a storage device or the like to another computer system via a transmission medium, or by a transmission wave in the transmission medium. Here, the "transmission medium" that transmits the program refers to a medium that has a function of transmitting information, such as a network (communication network) such as the Internet or a communication line (communication line) such as a telephone line. The above-mentioned program may also be a program for realizing part of the above-mentioned functions. Furthermore, the above-mentioned function may be realized in combination with a program already recorded in the computer system, that is, a so-called difference file (difference program).

[0109] Although an embodiment of the present invention has been described above with reference to the drawings, the specific configuration is not limited to this embodiment, and various modifications are also included within the scope that does not deviate from the spirit of the present invention.
