DETAILED DESCRIPTION OF THE INVENTION

[0028] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment according to one aspect of the present invention will now be described with reference to the accompanying drawings.

[0029] §1 Application Examples <Information management system 100 to which the present invention is applied> FIG. 1 is a diagram showing an example of an information management system 100 including an information terminal 5 of the present invention and a measuring device 1 that communicates wirelessly with this information terminal 5.

[0030] The measuring device 1 includes, for example, a weighing scale, a blood pressure monitor, a body composition monitor, and the like, capable of measuring biological information. The measuring device 1 is a measuring device that is used while placed on the ground or a stand. The measuring device 1 may also include an activity measuring device that measures activity amounts such as the number of steps, walking distance, or calories burned. The activity measuring device is a wearable measuring device that is carried by being attached to the user's body. In contrast to wearable measuring devices, non-wearable measuring devices (such as weighing scales and blood pressure monitors) are called non-wearable measuring devices. The measuring device 1 transmits the measured biological information, activity amounts, and the like to the information terminal 5 via wireless communication as user management measurement information. Note that FIG. 1 shows a blood pressure monitor capable of measuring blood pressure as the measuring device 1. However, the blood pressure monitor cuff and other components are not shown.

[0031] The information terminal 5 stores the management measurement information received from the measurement device 1 in a data storage unit within the information terminal 5. The information terminal 5 is also capable of wireless communication with devices other than the measurement device 1, and stores information acquired from external devices in a data storage unit within the information terminal 5. The information terminal 5 is an information processing device that analyzes various information acquired from the measurement device 1 and other external devices. The information terminal 5 is, for example, a terminal with a display, such as a smartphone, tablet terminal, laptop computer, desktop computer, or wearable terminal. The information terminal 5 may be configured to acquire management measurement information from a specific measurement device 1. The specific measurement device 1 from which the management measurement information is to be acquired may be registered in advance in the data storage unit of the information terminal 5.

[0032] Fig. 2 is a diagram showing an example in which an information terminal 5 is connected to a network. As shown in Fig. 2, the information terminal 5 may be connected to a cloud server 90 via a wide area network N such as the Internet. The information terminal 5 may transmit the management measurement information stored therein to the cloud server 90 via the wide area network N, and the cloud server 90 may manage the user's management measurement information as a database. Furthermore, the information terminal 5 may acquire the management measurement information managed in the cloud server 90 via the wide area network N, and use the acquired management measurement information.

[0033] §2 Configuration example <Configuration of Measuring Device 1> 3 is a block diagram showing the configuration of the measuring device 1. The measuring device 1 includes a display unit 11 that displays various information, an operation unit 12 operated by the user, a measuring unit 13 that measures biological information, activity levels, etc., a wireless communication unit 14 that can communicate wirelessly with external devices, and a sensor 15 that detects whether the measuring device 1 is stationary or tilted. The measuring device 1 also includes a RAM 16 that temporarily stores information, a data storage unit 17 that stores information and programs, and a controller 18 that controls the overall operation. The controller 18 is an example of a "processor" in the present invention. The operation unit 12 is an example of a "receiving unit" in the present invention.

[0034] Display unit 11 is configured with, for example, a liquid crystal display or an organic EL (Electro Luminescence) display. Operation unit 12 is a user interface that accepts user operations, such as buttons or a touch panel. Buttons include buttons that are physically provided on measurement device 1 and virtual buttons displayed on display unit 11.

[0035] The measurement unit 13 measures biological information such as weight, blood pressure, and body composition, or activity levels such as the number of steps, walking distance, and calories burned. What is measured varies depending on the object being measured by the measurement device 1.

[0036] The wireless communication unit 14 is a communication unit that performs short-range wireless communication, for example, a circuit (module) for performing communication according to the BLE (Bluetooth Low Energy (registered trademark)) standard. The wireless communication unit 14 transmits an advertising signal for performing wireless communication to an unspecified number of external devices via broadcast communication at a predetermined transmission cycle. The wireless communication unit 14 transmits the advertising signal including, for example, the name and attribute information of the measurement device 1, or information about the model. The BLE communication performed by the wireless communication unit 14 is communication that uses, for example, a 2.4 GHz frequency. The wireless communication unit 14 transmits management measurement information, such as biological information or activity levels measured by the measurement unit 13, to, for example, the information terminal 5 via BLE communication.

[0037] The sensor 15 is, for example, an acceleration sensor or an inclination sensor. The sensor 15 detects the stationary state of the measuring device 1 (the device itself) when a user wearing the measuring device 1 stops their activity. The sensor 15 also detects the stationary state of the measuring device 1 when the user wearing the measuring device 1 removes the measuring device 1 from the user's body and places it on a desk or the like. The sensor 15 also detects when the measuring device 1 is placed on the ground or a stand, or when it is tilted and held up.

[0038] The RAM 16 is configured by a semiconductor device such as a DRAM or SRAM, and serves as a working area for the controller 18 as well as temporarily storing information.

[0039] The data storage unit 17 is a recording medium that stores parameters, control programs, management measurement information, etc., required to realize predetermined processing. The data storage unit 17 is configured, for example, by a hard disk drive (HDD) or a semiconductor storage device (SSD).

[0040] Controller 18 performs predetermined processing by executing a control program. In this embodiment, for example, health management application software for the measuring device is pre-installed as a control program in data storage unit 17, and controller 18 performs predetermined processing by executing this health management application software.

[0041] For example, the controller 18 performs authentication by switching between a first authentication method that authenticates the connection target in response to a first operation on the operation unit 12 and a second authentication method that authenticates the connection target in response to a second operation different from the first operation on the operation unit 12. The controller 18 performs data communication with the information terminal 5 in response to the result of the authentication.

[0042] The "first operation" is, for example, pressing a communication button provided on the measurement device 1. The pressing of the communication button may be, for example, a short press or may include a long press. The "second operation" is, for example, a more complex operation than the "first operation." The "second operation" is an operation that only calls the communication function and does not also call other functions. Specifically, the second operation may be a long press of the communication button or multiple presses. The second operation is not limited to pressing the communication button, and may be, for example, performing a measurement with the measurement device 1 or tilting the measurement device 1 itself. The "first authentication method" is an authentication method in which, when the first operation is accepted, the device to which the connection is made is determined to be the device of an authorized user and data communication is enabled. In this case, even if the second operation is accepted, data communication is not enabled. The "second authentication method" is an authentication method in which, when the second operation is accepted, the device to which the connection is made is determined to be the device of an authorized user and data communication is enabled. In this case, even if the first operation is accepted, the state does not become one in which data communication is possible. "Data communication" refers to the transmission and reception of actual data, which is the purpose of wireless communication. For example, the controller 18 transmits biometric information to the information terminal 5.

[0043] Furthermore, the controller 18 switches the authentication method from the first authentication method to the second authentication method in response to a failure of authentication using the first authentication method, for example, due to a timeout caused by the first operation not being accepted within a predetermined time.

[0044] When the measuring device 1 is powered on, the controller 18 starts transmitting a first advertising signal including information instructing the information terminal 5 to output a first guidance message that prompts the operating unit 12 of the measuring device 1 to perform a first operation. When the controller 18 connects to the information terminal 5 while transmitting the first advertising signal, it performs authentication using the first authentication method. "Including instructing information" means, for example, setting a restriction flag and including information that the restriction flag is OFF in the advertising signal.

[0045] When authentication using the first authentication method fails, the controller 18 starts transmitting a second advertising signal including information instructing the information terminal 5 to output a second guide message that prompts the operation unit 12 of the measurement device 1 to perform a second operation. When the controller 18 connects to the information terminal 5 while transmitting the second advertising signal, it performs authentication using the second authentication method. "Including instructing information" means, for example, including information that the restriction flag is ON in the advertising signal.

[0046] The first operation on the measuring device 1 is assigned a function that causes the measuring device 1 to start communication with the information terminal 5, as well as a function different from the communication function. Therefore, when a third party is attempting to connect, there is a possibility that the third party may accidentally perform the first operation in an attempt to call up a "different function," resulting in fraudulent authentication success. However, even if this does not occur, if the first operation is a simple operation such as a short press, there is a possibility that the first operation may be performed unintentionally due to an accidental touch, etc. In contrast, the second operation on the measuring device 1 is assigned no functions other than the function that causes the measuring device 1 to start communication with the information terminal 5. The "function different from the communication function" is, for example, a function that causes the display unit 11 of the measuring device 1 to display the history of measurement results of the measuring device 1.

[0047] <Configuration of information terminal 5> 4 is a block diagram showing the configuration of the information terminal 5. The information terminal 5 includes a display unit 51 that displays various information, an operation unit 52 that the user operates, a first wireless communication unit 53 and a second wireless communication unit 54 that can communicate wirelessly with external devices. The information terminal 5 also includes a RAM 55 that temporarily stores information, a data storage unit 56 that stores information and programs, and a controller 57 that controls the overall operation. The controller 57 is an example of the "processor" of the present invention.

[0048] The display unit 51 is configured with, for example, a liquid crystal display or an organic EL display. The operation unit 52 is a user interface that accepts user operations such as buttons or a touch panel. The buttons include buttons that are physically provided on the information terminal 5 and virtual buttons displayed on the display unit 51.

[0049] The first wireless communication unit 53 is a communication unit that performs cellular communication, such as a circuit (module) for communication in accordance with standards such as 4G, 5G, and LTE (Long Term Evolution: registered trademark). The first wireless communication unit 53 is also a communication unit that performs wireless LAN communication, such as a circuit (module) for communication in accordance with standards such as Wi-Fi (registered trademark). The second wireless communication unit 54 is a communication unit that performs short-range wireless communication, such as a circuit (module) for communication in accordance with the BLE standard.

[0050] The second wireless communication unit 54 acquires management measurement information of the user measured by the measurement device 1, for example, by performing BLE communication with the wireless communication unit 14 of the measurement device 1. The second wireless communication unit 54 receives an advertising signal transmitted from the wireless communication unit 14 of the measurement device 1 by scanning. The second wireless communication unit 54 recognizes the measurement device 1 from the received advertising signal, and transmits a connection request to the measurement device 1 when it desires to establish a communication connection. After transmitting the advertising signal, the measurement device 1 waits for a connection request for a predetermined time, and upon receiving a connection request within the predetermined time, stops transmitting the advertising signal and switches to one-to-one connection communication with the other party of the connection request.

[0051] The RAM 55 is configured by a semiconductor device such as a DRAM or an SRAM, and temporarily stores information and also serves as a working area for the controller 57 .

[0052] The data storage unit 56 is a recording medium that stores parameters necessary to realize predetermined processing, control programs, and management measurement information acquired from the measurement device 1. The data storage unit 56 also stores images of, for example, each model of the measurement device 1 that can be connected to the information terminal 5 via wireless communication, along with their names, attributes, model numbers, etc. The data storage unit 56 is configured, for example, by a hard disk drive (HDD) or a semiconductor storage device (SSD).

[0053] Controller 57 performs predetermined processing by executing a control program. In this embodiment, for example, health management application software for an information terminal is pre-installed as a control program in data storage unit 56, and controller 57 performs predetermined processing by executing this health management application software. For example, when the health management application software for the information terminal is launched, controller 57 controls second wireless communication unit 54 to scan and receive an advertising signal. When controller 57 receives an advertising signal from measurement device 1, controller 57 controls second wireless communication unit 54 to send a connection request to measurement device 1 and acquire management measurement information from measurement device 1.

[0054] Furthermore, when the controller 57 detects a first advertising signal from the measurement device 1 via the second wireless communication unit 54, it outputs a first guide notification to the user, encouraging the user to perform a first operation on the measurement device 1. When the controller 57 detects a second advertising signal from the measurement device 1 that is different from the first advertising signal via the second wireless communication unit 54, it outputs a second guide notification to the user, encouraging the user to perform a second operation on the measurement device 1 that is different from the first operation.

[0055] §3 Example of operation <First Operation of Information Management System 100> 5 is a sequence diagram showing a first operation of the information management system 100. In the first operation, a user carrying an information terminal 5 (e.g., a smartphone) is about to measure the blood pressure of the user using the measurement device 1 (e.g., a blood pressure monitor), and the situation is such that only the user and the information terminal 5 carried by the user are present near the measurement device 1 (e.g., the situation shown in FIG. 1).

[0056] First, for example, a battery is inserted into the measuring device 1, and the measuring device 1 is powered on (step S11). The measuring device 1 starts transmitting an advertising signal (restriction flag = OFF) (step S12). As described above, the advertising signal is transmitted by broadcast communication to an unspecified number of external devices at a predetermined transmission cycle. The "restriction flag = OFF" is information that instructs the communicating device to output a type-1 guide message that prompts the first operation on the operation unit 12 of the measuring device 1. In this example, the first operation is a "short press" of the button. The measuring device 1 transmits this information about the restriction flag = OFF in the advertising signal. The advertising signal (restriction flag = OFF) is an example of a "first advertising signal" in the present invention.

[0057] When the health management application is launched (step S13), the information terminal 5 scans and detects an advertising signal (restriction flag = OFF) from the measuring device 1 (step S14). The information terminal 5 recognizes the device (measuring device 1) based on information about the device name, attributes, model, etc. included in the detected advertising signal (restriction flag = OFF), and displays the recognized device on the display unit 51 of the information terminal 5 (step S15). The information terminal 5 accepts a connection operation from the user on the display unit 51 to connect the information terminal 5 and the measuring device 1 (step S16). The "display device" in step S15 and the "accept connection operation" in step S16 will be described later with reference to the display image of the information terminal 5 in FIG. 6.

[0058] This causes a wireless communication connection process to be performed between the second wireless communication unit 54 of the information terminal 5 and the wireless communication unit 14 of the measuring device 1 (step S17). The connection process is performed by the second wireless communication unit 54 transmitting a connection request to the measuring device 1 based on the advertising signal (restriction flag=OFF), and the wireless communication unit 14 receiving the connection request and starting one-to-one connection communication with the measuring device 1 that is the connection request destination.

[0059] When connection processing between the information terminal 5 and the measuring device 1 (step S17) is performed, the information terminal 5 displays on the display unit 51 a guide for a "short press operation," which is an operation for pairing with the measuring device 1 (step S18). After displaying the guide for the short press operation, the information terminal 5 transmits a pairing authentication request to the measuring device 1 to authenticate that the user is authorized (step S19). The pairing authentication request is repeated at polling intervals (e.g., several hundred msec). If 30 seconds have passed without receiving a pairing authentication response (authentication OK) from the measuring device 1 in response to the pairing authentication request, the pairing authentication times out. Furthermore, the pairing authentication ends if the timeout occurs 10 times in a row, for example. The "short press operation guide display" in step S18 will be described later with reference to the display image of the information terminal 5 in FIG. 7.

[0060] When the measuring device 1 receives a pairing authentication request from the information terminal 5 while transmitting an advertising signal (restriction flag=OFF), it determines whether a "short press operation" has been performed on the measuring device 1, and if a "short press operation" has not been performed, it transmits a pairing authentication response (unauthenticated) in response to the pairing authentication request from the information terminal 5 (step S20). Furthermore, when the measuring device 1 receives a pairing authentication request from the information terminal 5, it transitions to a "short press operation standby state" in which it waits for a short press operation on the measuring device 1 (step S21). When a short press operation is performed on the measuring device 1, the measuring device 1 accepts the short press operation (step S22).

[0061] When the measurement device 1 accepts the short press operation, it transmits a pairing authentication response (authentication OK) (step S24) in response to the pairing authentication request (step S23) received thereafter from the information terminal 5.

[0062] When the information terminal 5 receives the pairing authentication response (authentication OK) from the measurement device 1, it stops the pairing authentication request and displays on the display unit 51 a "connection completion screen" notifying that the connection (pairing) with the measurement device 1 has been completed (step S25). The "connection completion screen" will be described later with reference to the display image of the information terminal 5 in FIG. 8.

[0063] This starts data communication between the measuring device 1 and the information terminal 5 (step S26).

[0064] <Example of image displayed on information terminal 5> 6 is a diagram showing an example of a connection operation acceptance screen 61 displayed on the information terminal 5 during pairing processing with the measuring device 1. The connection operation acceptance screen 61 is a screen displayed on the display unit 51 when the information terminal 5 recognizes a nearby measuring device 1, for example, based on a detected advertising signal (restriction flag=OFF). The connection operation acceptance screen 61 is displayed, for example, in steps S15 and S16 of FIG. 5.

[0065] As shown in Fig. 6, the connection operation acceptance screen 61 displays a message 61a, such as "A blood pressure monitor has been found," notifying that a wirelessly capable measurement device has been detected. The connection operation acceptance screen 61 also displays a device image 61b indicating the detected measurement device and a model number 61c indicating the model of the measurement device. The connection operation acceptance screen 61 also displays a connect button 61d that the user taps when they wish to connect to the displayed measurement device (blood pressure monitor). The connection operation acceptance screen 61 also displays a cancel button 61e for canceling this pairing process.

[0066] 7 is a diagram showing an example of an operation guide screen 62 displayed on the information terminal 5 during the pairing process with the measurement device 1. The operation guide screen 62 is a screen that is displayed when the connect button 61d in FIG. 6 is tapped. The operation guide screen 62 is a screen that provides guidance on the connection operation for pairing with the measurement device 1. The operation guide screen 62 is displayed, for example, in step S18 in FIG. 5.

[0067] 7, the operation guide screen 62 displays a target device display 62a indicating the measurement device to be connected, a model number 62b indicating the model of the measurement device, and a device image 62c showing an image of the measurement device. The operation guide screen 62 also displays a guidance message 62d that provides guidance on the operation, such as "Please press the button above," an operation button 62e indicating the position of the button to be operated on the measurement device to be operated, and a tap mark 62f that prompts the user to tap the operation button 62e. The operation guide screen 62 also displays a cancel button 62g for canceling the pairing process.

The connection completion screen 63 is a screen that is displayed when the operation button 62e (see FIG. 7) is tapped on the measurement device to be connected, for example, the measurement device 1 (sphygmomanometer) shown in FIG. 1. The connection completion screen 63 is a screen that notifies that pairing with the measurement device 1 has been authenticated. The connection completion screen 63 is displayed, for example, in step S25 of FIG. 5.

[0069] 8, a message 63a, such as "Connection successful," notifying that the connection with the measurement device has been completed is displayed on the connection completion screen 63. The connection completion screen 63 also displays a device image 63b indicating the connected measurement device and a model number 63c indicating the model of the measurement device.

[0070] <Second Operation of Information Management System 100> FIG. 9 is a sequence diagram showing a second operation (part 1) of the information management system 100. FIG. 10 is a sequence diagram showing a second operation (part 2) of the information management system 100. In the second operation, it is assumed that the measurement device 1 is placed on a stand, for example, and that an information terminal 5 carried by the user who owns the measurement device 1 (hereinafter referred to as the "person") and an information terminal 5A carried by a "third party" who is not the owner of the measurement device 1 are present within a range where wireless communication is possible with the measurement device 1. It is also assumed that a health management application is installed on both the information terminal 5 of the person and the information terminal 5A of the third party, and that it is possible to obtain managed measurement information of the measurement device 1 via wireless communication from the measurement device 1 on which the health management application for the measurement device is installed. Note that, as in the first operation, the measurement device 1 is a sphygmomanometer and the information terminal 5 is a smartphone. It is also assumed that the information terminal 5A has the same configuration as the information terminal 5.

[0071] First, for example, a battery is inserted into the measuring device 1, and the measuring device 1 is powered on (step S31). The measuring device 1 starts transmitting an advertising signal (restriction flag = OFF) (step S32). The advertising signal is transmitted via broadcast communication to an unspecified number of external devices at a predetermined transmission cycle. As described above, "restriction flag = OFF" is information that instructs the output of a first guide message to the operation unit 12 of the measuring device 1, which prompts the user to perform a first operation. The first operation is a "short press" of a button.

[0072] When a health management application is started by a third party (step S33), the information terminal 5A scans and detects an advertising signal (restriction flag = OFF) from the measuring device 1 (step S34). The information terminal 5A recognizes the device (measuring device 1) based on information about the device name, attributes, model, etc. included in the detected advertising signal (restriction flag = OFF), and displays the recognized device on the display unit 51 of the information terminal 5A (step S35). The information terminal 5A accepts a connection operation from the third party on the display unit 51 to connect the information terminal 5A and the measuring device 1 (step S36). The display images for "Display device" in step S35 and "Accept connection operation" in step S36 are the same as the display images of the information terminal 5 in FIG. 6 above.

[0073] As a result, a connection process for wireless communication is performed between the second wireless communication unit 54 of the information terminal 5A and the wireless communication unit 14 of the measuring device 1 (step S37).

[0074] When connection processing between the information terminal 5A and the measuring device 1 (step S37) is performed, the information terminal 5A displays on the display unit 51 a guide to a "short press operation" of the operation button, which is the first operation for pairing with the measuring device 1, based on the "restriction flag = OFF" information (step S38). The display image for the "short press operation guide display" in step S38 is the same as the display image of the information terminal 5 in FIG. 7 above. After displaying the short press operation guide, the information terminal 5A transmits a pairing authentication request to the measuring device 1 to authenticate that the user is an authorized user (step S39).

[0075] When the measuring device 1 receives a pairing authentication request from the information terminal 5A while transmitting an advertising signal (restriction flag=OFF), it determines whether a "short press operation" has been performed on the measuring device 1, and if a "short press operation" has not been performed, it transmits a pairing authentication response (unauthenticated) to the information terminal 5A in response to the pairing authentication request from the information terminal 5A (step S40). Furthermore, when the measuring device 1 receives a pairing authentication request from the information terminal 5A while transmitting an advertising signal (restriction flag=OFF), it transitions to a "short press operation standby state" in which it waits for a short press operation on the measuring device 1 (step S41).

[0076] The pairing authentication request is repeated at polling intervals (e.g., several hundred msec). If 30 seconds have passed without receiving a pairing authentication response (authentication OK) from the measurement device 1 in response to the pairing authentication request, that is, if 30 seconds have passed without a short press operation on the measurement device 1, the pairing authentication between the information terminal 5A and the measurement device 1 times out. When the pairing authentication times out, the next pairing authentication round starts, and the pairing authentication is set to end after a predetermined number of timeouts (e.g., 10 times) have occurred in succession. In this example, the measurement device 1 belongs to the user (principal) who possesses the information terminal 5. Furthermore, the person attempting to connect to the measurement device 1 is a third party who possesses the information terminal 5A, separate from the owner (principal) of the measurement device 1. For this reason, the third party will not perform a short press operation on the operation button of the user's measurement device 1, and the response to this pairing authentication request will repeatedly be a pairing authentication response (not authenticated). Furthermore, the owner (person) of measuring device 1 does not see the "short press operation guidance display" on information terminal 5, and therefore will not perform a short press operation on measuring device 1.

[0077] Next, the process proceeds to step S42 in FIG. 10. When the measuring device 1 detects the Nth timeout (step S42), it ends the pairing authentication process. Then, the measuring device 1 changes the information included in the advertising signal (information with restriction flag = OFF) and starts transmitting an advertising signal (with restriction flag = ON) (step S43). As described above, "restriction flag = ON" is information that instructs the operation unit 12 of the measuring device 1 to output a second guide message that prompts the user to perform a second operation. Furthermore, the second operation is a "long press" of a button. The advertising signal (restriction flag = ON) is an example of a "second advertising signal" in the present invention.

[0078] The information terminal 5A scans and detects an advertising signal (restriction flag = ON) from the measuring device 1 (step S44). The information terminal 5A recognizes the device (measuring device 1) based on information about the device name, attributes, model, etc. included in the detected advertising signal (restriction flag = ON), and displays the recognized device on the display unit 51 of the information terminal 5A (step S45). The information terminal 5A accepts a connection operation on the display unit 51 (step S46). This causes a wireless communication connection process to be performed between the information terminal 5A and the measuring device 1 (step S47). Note that the processes from step S45 to step S47 may be omitted if the processes from step S35 to step S37 described in FIG. 9 above are continuing.

[0079] When the connection process between the information terminal 5A and the measuring device 1 (step S47) is started, the information terminal 5A displays on the display unit 51 a guide to a "long press operation" of the operation button, which is the second operation for pairing with the measuring device 1, based on the "restriction flag = ON" information (step S48). The "long press operation guide display" in step S48 will be described later with reference to the display image of the information terminal 5A in FIG. 11. After displaying the long press operation guide, the information terminal 5A transmits a pairing authentication request to the measuring device 1 to authenticate that the user is an authorized user (step S49).

[0080] When the measuring device 1 receives a pairing authentication request from the information terminal 5A while transmitting an advertising signal (restriction flag = ON), it determines whether a "long press operation" has been performed on the measuring device 1, and if a "long press operation" has not been performed, it transmits a pairing authentication response (unauthenticated) in response to the pairing authentication request from the information terminal 5A (step S50). Furthermore, when the measuring device 1 receives a pairing authentication request from the information terminal 5A while transmitting an advertising signal (restriction flag = ON), it transitions the "short press operation standby state" for the measuring device 1, to which it transitioned in step S41 of Fig. 9, to a "long press operation standby state" (step S51).

[0081] The pairing authentication timeout is as described above. Therefore, a third party will not press and hold the operation button on the measuring device 1, and a pairing authentication response (unauthenticated) will be repeatedly sent in response to a pairing authentication request. Furthermore, the owner of the measuring device 1 (the person himself / herself) will not perform a long press on the measuring device 1 because he / she will not see the "long press guidance display" on the information terminal 5.

[0082] When the measurement device 1 detects the Mth timeout (step S52), it cancels the standby state for the long press operation of the measurement device 1, which it entered in step S51 (step S53). The Mth time is, for example, the number of times counted after the Nth time has passed. This reduces the risk of connection (pairing authentication) between the measurement device 1 and a third party's information terminal 5A that is trying to connect to the measurement device 1.

[0083] <Example of image displayed on information terminal 5A> 11 is a diagram showing an example of an operation guide screen 71 displayed on information terminal 5A during the pairing process with measurement device 1. Operation guide screen 71 is a screen that is displayed when a connection button (see, for example, connection button 61d in FIG. 6) displayed on display unit 51 is tapped. Operation guide screen 71 is a screen that provides guidance on the connection operation for pairing with measurement device 1. Operation guide screen 71 is displayed, for example, in step S48 in FIG. 10.

[0084] 11, the operation guide screen 71 displays a target device display 71a indicating the measurement device 1 to be connected, a model number 71b indicating the model of the measurement device 1, and a device image 71c showing an image of the measurement device 1. The operation guide screen 71 also displays a guidance message 71d that provides guidance on the operation content, such as "Please press and hold the above button," an operation button 71e that indicates the position of the button to be operated on the measurement device 1 to be operated, and a tap mark 71f that prompts the user to tap the operation button 71e. The operation guide screen 71 also displays a cancel button 71g for canceling the pairing process.

[0085] <Third Operation of Information Management System 100> 12 is a sequence diagram showing a third operation of the information management system 100. The third operation is an operation performed when a legitimate user of the measurement device 1 (the user himself / herself) attempts to connect to the measurement device 1 using the information terminal 5 in a situation where a connection attempt by a third party to the measurement device 1 is not authenticated in the second operation of the information management system 100 described above, and the standby state for a long press operation of the measurement device 1 is canceled (step S53 in FIG. 10).

[0086] The measuring device 1 transmits an advertising signal (restriction flag = ON) (step S72). The advertising signal (restriction flag = ON) is a signal that includes information instructing the measuring device 1 to output a second guide message that prompts the operating unit 12 to perform a second operation (a long press operation), as described in step S43 of FIG. 10 .

[0087] The operations from step S73 to step S77 are the same as the operations from step S13 to step S17 of the first operation shown in FIG.

[0088] When connection processing between the information terminal 5 and the measurement device 1 (step S77) is performed, the information terminal 5 displays on the display unit 51 a guide to a "long press operation" of the operation button, which is the second operation for pairing with the measurement device 1, based on the "restriction flag = ON" information (step S78). The display image for the "long press operation guide display" in step S78 is the same as the display image of the information terminal 5 in FIG. 11 above. After displaying the long press operation guide, the information terminal 5 transmits a pairing authentication request to the measurement device 1 to authenticate that the user is an authorized user (step S79).

[0089] When the measuring device 1 receives a pairing authentication request from the information terminal 5 while transmitting an advertising signal (restriction flag = ON), it determines whether a "long press" has been performed on the measuring device 1, and if a "long press" has not been performed, it transmits a pairing authentication response (unauthenticated) in response to the pairing authentication request from the information terminal 5 (step S80). Furthermore, when the measuring device 1 receives a pairing authentication request from the information terminal 5 while transmitting an advertising signal (restriction flag = ON), it transitions from the operation standby state released in step S53 of Fig. 10 to a "long press standby state" (step S81). When a long press is performed on the measuring device 1, the measuring device 1 accepts the long press (step S82).

[0090] The operations from step S83 to step S86 are the same as the operations from step S23 to step S26 of the first operation shown in FIG.

[0091] In each operation of the information management system 100 described above, if pairing authentication between the measuring device 1 and the information terminal is successful, the number of timeouts that has been counted up up to that point is initialized. The number of timeouts is also initialized in the same way when the measuring device 1 is restored to its factory default state. The number of timeouts is also initialized in the same way when the measuring device 1 is powered on, for example, when a battery is inserted into the measuring device 1 or when an AC adapter for the measuring device 1 is plugged in. If pairing authentication between the measuring device 1 and the information terminal is successful, or if the measuring device 1 is restored to its factory default state, the restriction flag included in the advertising signal is changed to OFF.

[0092] § 4 Processing of information terminals and measuring devices <Information terminal processing> 13 is a flowchart showing the processing of the information terminal 5. This processing is executed when the health management application is started up on the information terminal 5. Note that the information terminal 5A also performs the same processing.

[0093] The information terminal 5 executes a detection process for an advertising signal (step S101). Next, the information terminal 5 displays the detected device on the display unit 51 and enters a state in which it is ready to accept a connection operation from the user (step S102). For example, the information terminal 5 displays a connection operation acceptance screen 61 as shown in FIG. 6 on the display unit 51.

[0094] Next, the information terminal 5 determines whether or not a connection operation from the user has been accepted on the connection operation acceptance screen 61 (step S103). If a connection operation has not been accepted in step S103 (step S103: No), the information terminal 5 repeats the judgment process of step S103. However, for example, if the cancel button 61e (see FIG. 6) is tapped, this process ends. On the other hand, if a connection operation has been accepted in step S103 (step S103: Yes), the information terminal 5 performs connection processing with the detected device to be connected to (step S104).

[0095] Next, the information terminal 5 determines whether the restriction flag information included in the advertising signal transmitted from the device to be connected is "restriction flag = ON" (step S105). If the restriction flag information is not "restriction flag = ON", that is, if the restriction flag information is "restriction flag = OFF" (step S105: No), the information terminal 5 displays on the display unit 51 a guide prompting the user to perform a "short press operation", which is the first operation for pairing with the device to be connected (step S106). For example, the information terminal 5 displays on the display unit 51 an operation guide screen 62 as shown in FIG. 7.

[0096] On the other hand, if the information of the restriction flag is "restriction flag=ON" in step S105 (step S105: Yes), the information terminal 5 displays on the display unit 51 a guide prompting the user to perform a "long press operation," which is the second operation for pairing with the device to be connected (step S107). For example, the information terminal 5 displays on the display unit 51 an operation guide screen 71 as shown in FIG. 11.

[0097] After displaying a guide for a short press operation in step S106 or a guide for a long press operation in step S107, the information terminal 5 starts sending a pairing authentication request to authenticate whether the device to be connected is a device of a legitimate user (step S108).

[0098] Next, the information terminal 5 determines whether or not a pairing authentication response (authentication OK) has been received from the device to be connected as a response to the pairing authentication request (step S109). If the pairing authentication response (authentication OK) has not been received in step S109 (step S109: No), the information terminal 5 repeats the determination process of step S109. However, if the authentication of the pairing authentication request repeatedly transmitted at each polling interval times out, this process ends. On the other hand, if the pairing authentication response (authentication OK) has been received in step S109 (step S109: Yes), the information terminal 5 stops transmitting the pairing authentication request (step S110) and displays a connection completion screen on the display unit 51 to notify that connection (pairing) with the device to be connected has been completed (step S111). For example, the information terminal 5 displays a connection completion screen 63 as shown in FIG. 8 on the display unit 51.

[0099] The information terminal 5 starts data communication with the device that has been paired and authenticated (step S112).

[0100] <Processing of measuring equipment> Fig. 14 is a flowchart showing processing (part 1) of the measurement device 1. Fig. 15 is a flowchart showing processing (part 2) of the measurement device 1. This processing is executed when the power of the measurement device 1 is turned on.

[0101] The measurement device 1 starts transmitting an advertising signal (restriction flag=OFF) (step S121). Next, the measurement device 1 connects to an information terminal (for example, the information terminal 5) and determines whether a pair link authentication request has been received from the information terminal (step S122).

[0102] If a pairing authentication request is received in step S122 (step S122: Yes), the measuring device 1 determines whether the current state of the measuring device 1 is a standby state for a short press operation (step S123). If the current state of the measuring device 1 is not a standby state for a short press operation (step S123: No), the measuring device 1 transitions to a standby state for a short press operation (step S124). Then, the measuring device 1 determines whether a short press operation has been accepted (step S125). On the other hand, if the current state of the measuring device 1 is a standby state for a short press operation (step S123: Yes), the measuring device 1 proceeds directly to step S125 and determines whether a short press operation has been accepted (step S125).

[0103] If a short press operation is not received in step S125 (step S125: No), the measurement device 1 sends a pairing authentication response (unauthenticated) to the information terminal with which it is connected (step S126), and determines whether the pairing authentication timeout has reached the Nth timeout (step S127).

[0104] If the Nth timeout has not been reached in step S127 (step S127: No), the measurement device 1 returns to step S122 and repeats each process. If the Nth timeout has been reached in step S127 (step S127: Yes), the measurement device 1 proceeds to the process of step S130 in FIG.

[0105] On the other hand, if a short press operation is accepted in step S125 (step S125: Yes), the measuring device 1 transmits a pairing authentication response (OK) to the information terminal with which it is connected (step S128). Then, the measuring device 1 starts data communication with the information terminal that has been paired and authenticated (step S129). At the start of data communication, the measuring device 1 may stop transmitting an advertising signal (restriction flag=OFF).

[0106] If a pairing authentication request has not been received in step S122 (step S122: No), the measurement device 1 returns to step S122 and repeats each step.

[0107] 15, the measurement device 1 starts transmitting an advertising signal (restriction flag=ON) (step S130). Next, the measurement device 1 connects to an information terminal (for example, the information terminal 5) and determines whether a pair link authentication request has been received from the information terminal (step S131).

[0108] If a pairing authentication request has not been received in step S131 (step S131: No), the measurement device 1 repeats the process of step S131. If a pairing authentication request has been received in step S131 (step S131: Yes), the measurement device 1 determines whether the current state of the measurement device 1 is a standby state for a long press operation (step S132). If the measurement device 1 is not a standby state for a long press operation in step S132 (step S132: No), the measurement device 1 transitions to a standby state for a long press operation (step S133). Then, the measurement device 1 determines whether a long press operation has been accepted (step S134). On the other hand, if the measurement device 1 is a standby state for a long press operation in step S132 (step S132: Yes), the measurement device 1 proceeds directly to step S134 and determines whether a long press operation has been accepted (step S134).

[0109] If a long press operation has not been received in step S134 (step S134: No), the measurement device 1 sends a pairing authentication response (unauthenticated) to the information terminal of the connection partner (step S135), and then returns to step S131 to repeat each process.

[0110] If a long press operation is accepted in step S134 (step S134: Yes), the measurement device 1 transmits a pairing authentication response (OK) to the information terminal with which it is connected (step S136).The measurement device 1 then starts data communication with the information terminal that has been paired and authenticated (step S137).

[0111] As described above, the measurement device 1 has two authentication methods for authenticating a pairing target: a first authentication method that authenticates a pairing target in response to a short press on the operation unit 12 of the measurement device 1, and a second authentication method that authenticates a pairing target in response to a long press on the operation unit 12. When wirelessly communicating data with the information terminal 5, authentication is first performed using the first authentication method. If the authentication fails, the authentication method is switched from the first authentication method to the second authentication method and then performed again. With this configuration, for example, when an unauthorized connection attempt occurs from an information terminal 5A owned by a third party other than the owner (principal) of the measurement device 1 to the measurement device 1, the pairing authentication condition can be switched from a short press in the first authentication method to a long press in the second authentication method, thereby preventing the connection (pairing) between the information terminal 5A and the measurement device 1 from being authenticated by an operation on the measurement device 1 that is not intended to connect to the information terminal 5A. This prevents unauthorized access to the measurement device 1 from information terminals 5A other than the authorized information terminal 5.

[0112] Furthermore, when the power of the measuring device 1 is turned on, the measuring device 1 starts transmitting an advertising signal (restriction flag = OFF) that includes information instructing the information terminal 5 to output a first guide message that prompts a short press on the operation unit 12 of the measuring device 1, and when connecting to the information terminal 5 while the advertising signal (restriction flag = OFF) is being transmitted, authentication is performed using the first authentication method. In this way, by specifying the conditions for pairing with the information terminal to be connected, it is possible to prevent unauthorized access to the measuring device 1 from the information terminal 5A of a third party who is not a legitimate user.

[0113] Furthermore, if authentication using the first authentication method fails, the measurement device 1 starts transmitting an advertising signal (restriction flag = ON) that includes information instructing the information terminal 5 to output a second guide message that prompts a long press on the operation unit 12 of the measurement device 1, and when connecting to the information terminal 5 while the advertising signal (restriction flag = ON) is being transmitted, authentication using the second authentication method is performed. In this way, by specifying that the condition for pairing with the information terminal to be connected is a long press, which is more complicated than a short press, it is possible to further prevent unauthorized access to the measurement device 1 from the information terminal 5A of a third party who is not a legitimate user.

[0114] Furthermore, according to the measurement device 1, a short press on the measurement device 1 is assigned a function that causes the measurement device 1 to start communication with the information terminal 5 and a function different from that communication function (for example, a history check function), and a long press on the measurement device 1 is assigned no functions other than the function that causes the measurement device 1 to start communication with the information terminal 5. Therefore, by switching the authentication method for pairing authentication from a first authentication method that requires a short press to a second authentication method that requires a long press, it is possible to prevent connection (pairing) between the information terminal 5A and the measurement device 1 from being performed by an operation on the measurement device 1 that is not intended to be connected to the information terminal 5A. This makes it possible to prevent unauthorized access to the measurement device 1 from information terminals 5A other than the authorized information terminal 5.

[0115] Furthermore, when the information terminal 5 detects an advertising signal (restriction flag = OFF) from the measuring device 1, it outputs a type-1 guide message prompting the user to perform a short press on the measuring device 1, and when it detects an advertising signal (restriction flag = ON) from the measuring device 1, it outputs a type-2 guide message prompting the user to perform a long press on the measuring device 1. In this way, by switching the output of guide message prompting the user to perform an operation on the measuring device 1 in the information terminal 5 in response to switching of the authentication method for authenticating the pairing target in the measuring device 1, it is possible to make it difficult for third parties other than the legitimate user (the user) to attempt to connect to the measuring device 1, and to prevent unauthorized access to the measuring device 1 from a third party's information terminal 5A.

[0116] §6 Programs The control method of the measuring device 1 described in the above-described embodiment can be realized by executing a prepared control program on a computer. The control program is recorded on a computer-readable storage medium and executed by being read from the storage medium. The control program may be provided in a form stored in a non-transitory storage medium such as a flash memory, or may be provided via a network such as the Internet. The same applies to the control method of the information terminals 5 and 5A described above.
