Description

  The present invention relates to blood pressure measurement.

  High blood pressure is known to cause diseases with a high risk of hospitalization or death, such as stroke and myocardial infarction. For this reason, hypertensive patients may be disadvantaged in taking life insurance and medical insurance. Specifically, patients with high blood pressure may be paid a higher amount of insurance than ordinary subscribers, or may be given special conditions at the time of enrollment.

  In addition, for example, a country, a local government, a company, or the like may operate a health promotion program that gives an incentive when the blood pressure of a participant is improved or when the blood pressure of the participant is maintained in a good state.

  In recent years, blood pressure measuring devices that can transmit blood pressure data externally via a communication device in conjunction with a communication device such as a smartphone have been put on the market. The insurance company or the program operator can efficiently collect blood pressure data by making the insurance application applicant or the program participant use the blood pressure measuring device.

  An applicant who deceives an insurance company and wants to take out insurance on favorable terms may measure the blood pressure of others who are in good condition. Similarly, program participants who try to fraud incentives from the program operator may also measure blood pressure data of others with good blood pressure. It is not easy to distinguish blood pressure data obtained by such impersonation from genuine blood pressure data.

The communication unit receives blood pressure data from the blood pressure measurement device. The communication unit transmits blood pressure data when an electrical signal is received, and does not transmit blood pressure data when an electrical signal is not received.

  Hereinafter, embodiments will be described with reference to the drawings. Hereinafter, elements that are the same as or similar to elements already described are denoted by the same or similar reference numerals, and redundant descriptions are basically omitted.

(First embodiment)
The blood pressure measurement device according to the first embodiment is connected to a communication device, and transmits blood pressure data to the outside (for example, a server) via the communication device. In other words, the communication device according to the present embodiment is connected to the blood pressure measurement device, receives blood pressure data from the blood pressure measurement device, and transmits the received blood pressure data to the outside.

  The blood pressure measurement device according to the first embodiment may be, for example, a wristwatch-type wearable terminal shown in FIG. The blood pressure measurement device 100 includes, for example, a user's systolic blood pressure SYS and diastolic blood pressure in addition to information displayed on a general clock such as today's date and current time. Biometric information such as DIA and pulse rate PULSE is displayed. The blood pressure measurement device 100 can continuously measure the user's biological information, for example, every beat, and display the latest SYS and DIA.

  The blood pressure measurement device 100 is not limited to a wearable type and may be a stationary type. The blood pressure measurement device 100 may always measure blood pressure, or may measure blood pressure in response to an instruction from the user or the communication device 200.

  The blood pressure measurement device 100 is connected to the communication device 200 as illustrated in FIG. The blood pressure measurement device 100 and the communication device 200 may be connected using short-range wireless communication such as Bluetooth (registered trademark). The blood pressure measurement device 100 transmits blood pressure data to the communication device 200 as necessary.

  The communication apparatus 200 is connected to the server 300 via the network NW as illustrated in FIG. The communication device 200 transmits authentication data to the server 300 via the network NW in order to perform user authentication of the communication device 200. The communication device 200 acquires blood pressure data from the blood pressure measurement device 100 after user authentication. As will be described later, the communication device 200 determines whether or not the blood pressure data represents the blood pressure measurement result of the authenticated user, and the blood pressure data confirmed to represent the blood pressure measurement result of the authenticated user. It transmits to the server 300 via the network NW.

  In addition, the communication device 200 may display the blood pressure data transmitted by the blood pressure measurement device 100 in a graph. The communication device 200 may be installed with an application for managing blood pressure data.

  Server 300 accumulates blood pressure data transmitted from communication device 200. The server 300 transmits the blood pressure data of the user in response to an access from a PC (Personal Computer) of the insurance company or the program operator, for example, in order to provide a user's insurance enrollment assessment, a health promotion program performance evaluation, and the like. May be.

  As illustrated in FIG. 1, the blood pressure measurement device 100 according to the first embodiment includes a blood pressure sensor 101, a biological sensor 102, a clock unit 103, a user input unit 104, a communication unit 105, and display control. Unit 106, display unit 107, and sensor control unit 108.

  The blood pressure sensor 101 measures the blood pressure of the user (of the blood pressure measurement device 100), generates blood pressure data, and sends the blood pressure data to the communication unit 105 and the display control unit 106. The blood pressure data may include values of systolic blood pressure and diastolic blood pressure for each beat, but is not limited thereto. Each blood pressure data can be associated with a measurement time set based on the time information received from the clock unit 103.

  The blood pressure sensor 101 can include a blood pressure sensor (hereinafter referred to as a continuous blood pressure sensor) that can continuously measure a user's blood pressure for each beat. The continuous blood pressure sensor may continuously measure a user's blood pressure from a pulse wave transit time (PTT), or may realize continuous measurement by a tonometry method or other techniques.

  The blood pressure sensor 101 may include a blood pressure sensor that cannot be continuously measured (hereinafter referred to as a discontinuous blood pressure sensor) in addition to the continuous blood pressure sensor. For example, a discontinuous blood pressure sensor measures a user's blood pressure using a cuff as a pressure sensor (oscillometric method).

  Discontinuous blood pressure sensors (particularly, oscillometric blood pressure sensors) tend to have higher measurement accuracy than continuous blood pressure sensors. Therefore, the blood pressure sensor 101 is replaced with a continuous blood pressure sensor triggered by the satisfaction of some condition (for example, the blood pressure data of the user measured by the continuous blood pressure sensor indicates a predetermined high risk state). The blood pressure may be measured with higher accuracy by operating the discontinuous blood pressure sensor.

  The biological sensor 102 measures at least one type of biological information other than the blood pressure of the user (of the blood pressure measurement device 100), generates first biological data, and transmits the first biological data to the communication unit 105 and display control. Send to part 106. The first biometric data is not limited to simply monitoring the biometric information of the user, but is used for authentication of blood pressure data to be described later. The first biological data is typically pulse wave data, but can include electrocardiographic data, heart rate data, pulse data, body temperature data, and the like. Each of the first biological data can be associated with a measurement time set based on the time information received from the clock unit 103.

  When the first biological data is used for authentication of blood pressure data, the biological sensor 102 overlaps with a period during which the blood pressure sensor 101 performs measurement for generating the blood pressure data (that is, completely or partially matches). The first biological data is generated based on the measurement in the period. Thereby, it can be guaranteed that the blood pressure data and the first biological data represent the measurement results from the same living body.

  The operations of the blood pressure sensor 101 and the biological sensor 102 can be controlled by the sensor control unit 108. Specifically, for example, the blood pressure measurement start instruction received from the communication device 200 by the communication unit 105 may be given to the sensor control unit 108, and the sensor control unit 108 may activate the blood pressure sensor 101 and the biosensor 102 as a trigger.

  Note that the sensor control unit 108 does not necessarily have to activate the blood pressure sensor 101 and the biological sensor 102 together. For example, a biological information measurement start instruction may be defined separately from the blood pressure measurement start instruction. In this case, the sensor control unit 108 can activate the blood pressure sensor 101 and the biological sensor 102 individually. Alternatively, if the blood pressure sensor 101 is a continuous blood pressure sensor, the blood pressure sensor 101 can always operate, and therefore the sensor control unit 108 may control only the biological sensor 102 to be activated. In this case, the blood pressure measurement start instruction may not be defined.

  The clock unit 103 generates time information indicating the current time at a predetermined cycle, and sends the time information to the blood pressure sensor 101, the biological sensor 102, and the display control unit 106. The time information can be used as the measurement time of blood pressure data by the blood pressure sensor 101, the measurement time of first biological data by the biological sensor 102, and the like.

  The clock unit 103 may have a calendar function. That is, the clock unit 103 may generate date information representing today's date, for example, and send it to the display control unit 106. For example, blood pressure does not fluctuate in the same way every day, but may show different fluctuating trends for each day of the week and for each season, so date information is useful for analyzing biological information.

  The user input unit 104 is a button, dial, crown, or the like for receiving user input. Or the combination of the user input part 104 and the display part 107 mentioned later may be mounted, for example using a touch screen. The user input may be an operation for controlling the display screen of the display unit 107, an operation for instructing the start of measurement of blood pressure or biological information other than blood pressure, and the like.

  The communication unit 105 exchanges data with an external device such as the communication device 200 via the network NW. The communication unit 105 may perform one or both of wireless communication and wired communication. As an example, the communication unit 105 may perform short-range wireless communication such as Bluetooth with the communication device 200, for example.

  Specifically, the communication unit 105 receives a blood pressure measurement start instruction from the communication device 200 and gives this to the sensor control unit 108. Further, the communication unit 105 receives blood pressure data and first biological data from the blood pressure sensor 101 and the biological sensor 102 and transmits them to the communication device 200.

  The display control unit 106 controls the display unit 107. Specifically, the display control unit 106 generates screen data and sends it to the display unit 107. For example, the display control unit 106 can generate screen data based on blood pressure data from the blood pressure sensor 101, first biological data from the biological sensor 102, time information and date information from the clock unit 103, and the like. The display control unit 106 may select information used to generate screen data in accordance with a user input corresponding to an operation for controlling the display screen of the display unit 107.

  The display unit 107 is, for example, a liquid crystal display or an organic EL (electroluminescence) display. The display unit 107 can notify the user of various information by displaying the screen data from the display control unit 106. Specifically, the display unit 107 may display blood pressure, biological information other than blood pressure (for example, electrocardiogram, heart rate, pulse wave, pulse rate, body temperature, etc.), current time, calendar, and the like.

  The sensor control unit 108 controls the operations of the blood pressure sensor 101 and the biological sensor 102. For example, the sensor control unit 108 may activate the blood pressure sensor 101 and the biological sensor 102 according to the operation state of the communication unit 105. Specifically, the sensor control unit 108 may activate the blood pressure sensor 101 and the biological sensor 102, triggered by the communication unit 105 receiving a blood pressure measurement start instruction or the like. Alternatively, the sensor control unit 108 may activate the blood pressure sensor 101 and the biological sensor 102 in response to an explicit measurement start instruction from the communication unit 105. The sensor control unit 108 may activate the blood pressure sensor 101 or the biological sensor 102 when receiving a user input corresponding to an operation for instructing measurement start of blood pressure or biological information other than blood pressure.

  As illustrated in FIG. 2, the communication device 200 according to the first embodiment includes a communication unit 201, a biosensor 202, a comparison unit 203, and a sensor control unit 204.

  The communication unit 201 exchanges data with external devices such as the blood pressure measurement device 100 and the server 300 via the network NW. The communication unit 201 may perform one or both of wireless communication and wired communication. As an example, the communication unit 201 may perform short-range wireless communication such as Bluetooth with the blood pressure measurement device 100, for example.

  Specifically, the communication unit 201 transmits authentication data for user authentication to the server 300 and then receives an authentication result from the server 300. The authentication data is used in a known authentication technology, but fingerprint, iris, vein, voiceprint and other data used for biometric authentication are suitable from the viewpoint of preventing impersonation more reliably.

  The communication unit 201 transmits a blood pressure measurement start instruction to the blood pressure measurement device 100 in order to acquire blood pressure data to be transmitted to the server 300. The communication unit 201 receives blood pressure data and first biological data from the blood pressure measurement device 100. The communication unit 201 sends the first biological data to the comparison unit 203 for authentication of blood pressure data. The communication unit 201 receives the blood pressure data authentication result from the comparison unit 203. If the authentication is successful, the communication unit 201 transmits the blood pressure data to the server 300. If the authentication fails, the communication unit 201 does not transmit the blood pressure data to the server 300. Disable it by destroying it).

  The communication unit 201 explicitly issues a measurement start instruction for biological information other than blood pressure to the sensor control unit 204, for example, at the start of execution of user authentication (for example, access to the server 300) or when a blood pressure measurement start instruction is transmitted. May be given. Alternatively, the operation state of the communication unit 201 may be referred to by the sensor control unit 204, and the operation of the sensor control unit 204 may be determined using a specific operation of the communication unit 201 as a trigger.

  In order to prevent impersonation such as handing over the communication device 200 to another person who is already wearing the blood pressure measurement device 100 after the user authentication is completed and before the blood pressure measurement is started, the authentication is also performed after the user authentication is completed. Data may be regenerated. If an authentication error is detected before blood pressure measurement is completed (for example, a fingerprint cannot be obtained or has been switched to another person), blood pressure measurement may be stopped, or blood pressure data May be invalidated. Alternatively, user authentication may be performed after the start of blood pressure measurement rather than before the start of blood pressure measurement.

  The biometric sensor 202 obtains second biometric data by measuring at least one type of biometric information other than the blood pressure of the user (of the communication device 200), and sends the second biometric data to the comparison unit 203. The second biological data represents the measurement result of the same type of biological information as the first biological data described above. The second biometric data is not limited to simply monitoring the biometric information of the user, but is used for authentication of blood pressure data. The second biological data is typically pulse wave data, but can include electrocardiographic data, heartbeat data, pulse data, body temperature data, and the like. Each of the second biological data can be associated with a measurement time set based on time information received from a clock unit (not shown).

  When the second biometric data is used for authentication of blood pressure data, the biometric sensor 202 generates the second biometric data based on the measurement in a period including the generation time of the authentication data. Thereby, it can be guaranteed that the second biometric data represents the measurement result of the biometric information of the authenticated user. Further, the biosensor 202 generates second biometric data based on the measurement in a period that overlaps (that is, completely or partially matches) with the period in which the biosensor 102 performs measurement for generating the first blood pressure data. . As a result, the first biometric data and the second biometric data can be compared.

  The comparison unit 203 receives first biometric data from the communication unit 201 and receives second biometric data from the biosensor 202. The comparison unit 203 compares the first biological data and the second biological data, and authenticates the blood pressure data by determining whether or not a predetermined condition is satisfied. The comparison unit 203 notifies the communication unit 201 of the authentication result of the blood pressure data. The predetermined condition may be set to a condition that is established (with high probability) when the first biological data and the second biological data represent measurement results from the same living body.

  The first biometric data represents the measurement result of the biometric information of the person to be measured in the blood pressure data, and the second biometric data represents the measurement result of the biometric information of the authenticated user. Therefore, if the measurement results expressed by the two substantially match, it can be estimated that there is a high possibility that the authenticated user matches the person to be measured in the blood pressure data (impersonation is not performed). However, the two do not need to coincide completely, and errors depending on the measurement accuracy of the biosensor 102 and the biosensor 202, the measurement site of the biometric information, the synchronism of the measurement time, and the like may be considered. On the other hand, if there is a significant difference between the two, it can be estimated that there is a high possibility that the authenticated user does not match the person to be measured in the blood pressure data (impersonation is performed).

  The sensor control unit 204 controls the operation of the biosensor 202. For example, the sensor control unit 204 may activate the biometric sensor 202 according to the operation state of the communication unit 201. Specifically, the sensor control unit 204 activates the biosensor 202 by using, for example, the communication unit 201 starting user authentication processing or the communication unit 201 transmitting a blood pressure measurement start instruction to the blood pressure measurement device 100. May be. Alternatively, the sensor control unit 204 may activate the biometric sensor 202 in response to an explicit measurement start instruction from the communication unit 201. In addition, the sensor control unit 204 may activate the biometric sensor 202 when receiving a user input corresponding to an operation for instructing measurement start of biometric information.

  An operation example of the communication apparatus 200 is shown in FIG. In this operation example, blood pressure measurement is performed after completion of user authentication, but user authentication may be performed during blood pressure measurement or after completion of blood pressure measurement.

  In the operation example of FIG. 5, first, user authentication is executed (step S301). For example, a user's fingerprint is read by a fingerprint sensor (not shown), and fingerprint data is generated. The communication unit 201 transmits fingerprint data as authentication data to the server 300 via the network NW. The server 300 notifies that the user authentication is successful if the received fingerprint data matches the fingerprint data of the user registered in advance, and otherwise notifies that the user authentication has failed. If the user authentication is successful, the process proceeds to step S303; otherwise, the process proceeds to step S309 (step S302).

  In step S <b> 303, the communication unit 201 transmits a blood pressure measurement start instruction to the blood pressure measurement device 100. Furthermore, with step S303 as a trigger, the sensor control unit 204 activates the biosensor 202, and the biosensor 202 measures biometric information (step S304).

  In this operation example, it is preferable that the authentication data is regenerated even after the completion of step S301 in order to prevent impersonation after step S301. Alternatively, if step S304 is started before the generation of authentication data in step S301, it is possible to prevent spoofing after step S301 without regenerating the authentication data. That is, if the user tries to hand over the communication device 200 to another person who has already worn the blood pressure measurement device 100 after the generation of the authentication data, a measurement error of the second biological data occurs, so that the blood pressure measurement is stopped, or , Blood pressure data authentication fails.

  When the measurement of blood pressure and biological information is successfully completed in the blood pressure measurement device 100, the communication unit 201 can receive blood pressure data and first biological data (step S305). The comparison unit 203 compares the received first biometric data with the second biometric data generated in step S304 (step S306). If the two substantially match (that is, the blood pressure data is successfully authenticated), the process proceeds to step S308; otherwise, the process proceeds to step S309 (step S307).

  In step S308, the communication unit 201 transmits the received blood pressure data to the server 300 via the network NW, and the operation in FIG. On the other hand, in step S309, the communication apparatus 200 performs predetermined error processing, and the operation in FIG.

  FIG. 6 shows an operation example of the blood pressure measurement device 100 corresponding to the operation example of FIG. When communication unit 105 receives a blood pressure measurement start instruction from communication device 200, the process proceeds to step S402 (step S401).

  In step S402, triggered by reception of the blood pressure measurement start instruction, the sensor control unit 108 activates the blood pressure sensor 101 and the biological sensor 102, and the blood pressure sensor 101 and the biological sensor 102 measure blood pressure and biological information, respectively. The communication unit 105 transmits the blood pressure data and the first biological data generated in step S402 to the communication device 200 (step S403), and the operation in FIG.

  As described above, the blood pressure measurement device according to the first embodiment measures the biological information other than the blood pressure in addition to the blood pressure, and represents the measurement result of the biological information from the same person as the blood pressure data. Generate biometric data. The communication device according to the present embodiment measures the biological information of a specific user and generates second biological data associated with the user. When the first biometric data and the second biometric data satisfy a predetermined condition (for example, the measurement results represented by both data are substantially coincident), it is highly likely that the person to be measured in the blood pressure data coincides with a specific user. Therefore, the communication device transmits the blood pressure data to the server. On the other hand, when the first biometric data and the second biometric data do not satisfy a predetermined condition (for example, substantially match), it can be estimated that there is a high possibility that the person to be measured in the blood pressure data does not match a specific user. Therefore, this communication device does not transmit this blood pressure data to the server. Therefore, according to these blood pressure measurement devices and communication devices, it is possible to detect whether or not the blood pressure data represents the measurement result of the blood pressure of a specific user and prevent impersonation.

(Second Embodiment)
The blood pressure measurement device and communication device according to the second embodiment are the same as the blood pressure measurement device and communication device according to the first embodiment in the basic configuration and operation except for the authentication method of blood pressure data. Therefore, hereinafter, description of matters common between the blood pressure measurement device and the communication device according to the second embodiment and the blood pressure measurement device and the communication device according to the first embodiment may be omitted. The same applies to the descriptions of the third embodiment and the fourth embodiment.

  As illustrated in FIG. 7, the blood pressure measurement device 500 according to the second embodiment includes a blood pressure sensor 101, a clock unit 103, a user input unit 104, a communication unit 505, a display control unit 106, and a display. Unit 107, sensor control unit 108, and electrical signal transmission unit 509.

  The blood pressure sensor 101 obtains blood pressure data by measuring the blood pressure of the user (of the blood pressure measurement device 500), and sends the blood pressure data to the communication unit 505 and the display control unit 106.

  The operation of the blood pressure sensor 101 can be controlled by the sensor control unit 108. Specifically, the blood pressure measurement start instruction received from the communication device 600 by the communication unit 505 may be given to the sensor control unit 108, and the sensor control unit 108 may activate the blood pressure sensor 101 as a trigger.

  Note that if the blood pressure sensor 101 is a continuous blood pressure sensor, the blood pressure sensor 101 may always operate, so the sensor control unit 108 may not have to perform activation control of the blood pressure sensor 101. In this case, the blood pressure measurement start instruction may not be defined.

  The communication unit 505 exchanges data with an external device such as the communication device 600 via the network NW. The communication unit 505 may perform one or both of wireless communication and wired communication. As an example, the communication unit 505 may perform short-range wireless communication such as Bluetooth with the communication device 600, for example.

  Specifically, the communication unit 505 receives a blood pressure measurement start instruction from the communication device 600 and gives this to the sensor control unit 108. At this time, the communication unit 505 may give an activation instruction to the electrical signal transmission unit 509. The communication unit 505 receives blood pressure data from the blood pressure sensor 101 and transmits the blood pressure data to the communication device 600.

  The sensor control unit 108 controls the operation of the blood pressure sensor 101. For example, the sensor control unit 108 may activate the blood pressure sensor 101 according to the operation state of the communication unit 105. Specifically, the sensor control unit 108 may activate the blood pressure sensor 101, triggered by the communication unit 105 receiving a blood pressure measurement start instruction or the like. Alternatively, the sensor control unit 108 may activate the blood pressure sensor 101 in response to an explicit measurement start instruction from the communication unit 105. The sensor control unit 108 may activate the blood pressure sensor 101 when receiving a user input corresponding to an operation for instructing the start of blood pressure measurement.

  The electrical signal transmission unit 509 can transmit an electrical signal to the communication device 600 when the blood pressure measurement device 500 and the communication device 600 are in contact with a living body. Specifically, the electrical signal transmission unit 509 can include an electrode that applies an electrical signal to the living body when in contact with the living body. Then, the electrical signal applied to the living body by this electrode is conducted to the communication device 600 through the living body. This electrical signal is generated by a signal source inside or outside the electrical signal transmission unit 509. This electrical signal can be used for authentication of blood pressure data.

  Specifically, when the blood pressure measurement device 500 and the communication device 600 are in contact with the user's arm and hand, respectively, as illustrated in FIG. 9, the blood pressure measurement device 500, the living body (the user's arm and hand). ) And the communication device 600 is formed. Therefore, the communication apparatus 600 can receive an electrical signal (current). For example, the communication device 600 may detect the reception of an electrical signal when the voltage across the resistor for current detection provided on the communication device 600 side exceeds a threshold value. On the other hand, if the person to be measured of blood pressure data is not in contact with communication device 600, such a circuit is not formed, and communication device 600 cannot receive an electrical signal. That is, the communication device 600 can detect whether or not the blood pressure measurement device 500 and the communication device 600 are in contact with the same living body based on whether or not an electric signal can be received.

  When the electrical signal is used for blood pressure data authentication, the signal source inside or outside the electrical signal transmission unit 509 overlaps with the period during which the blood pressure sensor 101 performs measurement for generating the blood pressure data (that is, An electrical signal is generated during a period of complete or partial coincidence). Accordingly, it can be ensured that the person to be measured of blood pressure data has been in contact with the communication device 600 at least over a period in which the electrical signal is received by the communication device 600.

  In addition, when an electrical signal is used for authentication of blood pressure data, an internal or external signal source of the electrical signal transmission unit 509 generates an electrical signal during a period including generation of authentication data in the communication device 600. Is preferred. Accordingly, it can be ensured that the blood pressure measurement device 500 has been in contact with the authenticated user for at least the period when the electrical signal is received by the communication device 600.

  As illustrated in FIG. 8, the communication device 600 according to the second embodiment includes a communication unit 601 and an electric signal receiving unit 605.

  The communication unit 601 exchanges data with external devices such as the blood pressure measurement device 500 and the server 300 via the network NW. The communication unit 601 may perform one or both of wireless communication and wired communication. As an example, the communication unit 601 may perform short-range wireless communication such as Bluetooth with the blood pressure measurement device 500, for example.

  Specifically, the communication unit 601 transmits authentication data for user authentication to the server 300 and then receives an authentication result from the server 300. The authentication data is used in a known authentication technology, but fingerprint, iris, vein, voiceprint and other data used for biometric authentication are suitable from the viewpoint of preventing impersonation more reliably.

  The communication unit 601 transmits a blood pressure measurement start instruction to the blood pressure measurement device 500 in order to acquire blood pressure data to be transmitted to the server 300. The communication unit 601 receives blood pressure data from the blood pressure measurement device 500. The communication unit 601 receives the authentication result of the blood pressure data from the electrical signal receiving unit 605. If the authentication is successful, the communication unit 601 transmits the blood pressure data to the server 300. If the authentication fails, the communication unit 601 does not transmit the blood pressure data to the server 300 (blood pressure Invalidate it by destroying the data).

  In order to prevent impersonation such as handing over the communication device 600 to another person who is already wearing the blood pressure measurement device 500 after the user authentication is completed and before the blood pressure measurement is started, the authentication is also performed after the user authentication is completed. Data may be regenerated. If an authentication error is detected before blood pressure measurement is completed (for example, a fingerprint cannot be obtained or has been switched to another person), blood pressure measurement may be stopped, or blood pressure data May be invalidated. Alternatively, user authentication may be performed after the start of blood pressure measurement rather than before the start of blood pressure measurement.

  The electrical signal receiving unit 605 receives an electrical signal from the blood pressure measurement device 500 when the blood pressure measurement device 500 and the communication device 600 are in contact with a living body. Specifically, the electrical signal receiving unit 605 can include an electrode that receives an electrical signal conducted through the living body when in contact with the living body. The electrical signal receiving unit 605 authenticates blood pressure data by determining whether or not to receive an electrical signal. The electric signal receiving unit 605 notifies the communication unit 601 of the authentication result of the blood pressure data.

  The fact that the electric signal has been received means that the communication device 600 has been in contact with the person to be measured for blood pressure data over the electric signal reception period (which overlaps with the blood pressure measurement period). . Therefore, if the electric signal can be received, it can be estimated that the authenticated user is likely to match the person to be measured in the blood pressure data (no impersonation is performed). On the other hand, if the electrical signal cannot be received, it can be estimated that there is a high possibility that the authenticated user does not match the person to be measured of blood pressure data (impersonation is performed).

  However, if authentication of blood pressure data is triggered only by reception of an electrical signal, for example, if a weak electrical signal due to noise is received, a random electrical signal that is intentionally applied to deceive the authentication of blood pressure data is received. Even when a signal is received, blood pressure data may be authenticated.

  Therefore, for example, conditions may be defined in advance using parameters such as amplitude, phase, and frequency, and blood pressure data may be authenticated by triggering the reception of an electrical signal that satisfies such conditions. Alternatively, a modulation signal carrying specific data as used in human body communication technology may be used as an electrical signal for authenticating blood pressure data. In this case, the electrical signal received by the electrical signal receiving unit 605 is demodulated, and the blood pressure data is authenticated by using a specific data as a trigger.

  An operation example of the communication apparatus 600 is shown in FIG. In this operation example, blood pressure measurement is performed after completion of user authentication, but user authentication may be performed during blood pressure measurement or after completion of blood pressure measurement.

  In the operation example of FIG. 10, user authentication is first executed (step S701). For example, a user's fingerprint is read by a fingerprint sensor (not shown), and fingerprint data is generated. The communication unit 601 transmits fingerprint data as authentication data to the server 300 via the network NW. The server 300 notifies that the user authentication is successful if the received fingerprint data matches the fingerprint data of the user registered in advance, and otherwise notifies that the user authentication has failed. If the user authentication is successful, the process proceeds to step S703; otherwise, the process proceeds to step S707 (step S702).

  In step S703, the communication unit 601 transmits a blood pressure measurement start instruction to the blood pressure measurement device 500. If the electric signal receiving unit 605 cannot receive the electric signal after transmitting the blood pressure measurement start instruction (that is, during the blood pressure measurement), the blood pressure measuring device 500 is attached to a person different from the user authenticated in step S701. Therefore, the process proceeds to step S707 (step S704). On the other hand, if the electrical signal can be received, it can be assumed that blood pressure measurement apparatus 500 is attached to the user who has been authenticated in step S701, and therefore the reception of blood pressure data is awaited (step S705).

  In this operation example, it is preferable that the authentication data is regenerated after step S301 is completed in order to prevent impersonation after step S701. Alternatively, if the blood pressure measurement device 500 generates an electrical signal before the generation of the authentication data in step S701, it is possible to prevent impersonation after step S701 without regenerating the authentication data. That is, if the user tries to hand over the communication device 600 to another person who is already wearing the blood pressure measurement device 500 after generating the authentication data, an electric signal reception error occurs, so that the blood pressure measurement is stopped, or the blood pressure data Authentication fails.

  As a result of the above-described step S704, since it is confirmed that the received blood pressure data represents the blood pressure measurement result of the authenticated user, the communication unit 601 transmits the blood pressure data to the server 300 via the network NW. Then, the operation of FIG. 10 ends (step S706). On the other hand, in step S707, the communication apparatus 600 performs predetermined error processing, and the operation in FIG.

  FIG. 11 shows an operation example of the blood pressure measurement device 500 corresponding to the operation example of FIG. When communication unit 505 receives a blood pressure measurement start instruction from communication device 600, the process proceeds to step S802 (step S801).

  In step S802, the signal source inside or outside the electric signal transmission unit 509 generates an electric signal, for example, triggered by reception of a blood pressure measurement start instruction. This signal source may generate an electrical signal triggered by an event other than reception of a blood pressure measurement start instruction, or may always generate an electrical signal.

  On the other hand, triggered by reception of a blood pressure measurement start instruction, the sensor control unit 108 activates the blood pressure sensor 101, and the blood pressure sensor 101 measures blood pressure. The communication unit 505 transmits the blood pressure data generated in step S803 to the communication device 600 (step S804), and the operation in FIG.

  As described above, the blood pressure measurement device according to the second embodiment generates an electrical signal during blood pressure measurement and applies it to the subject. The communication device according to the present embodiment detects whether or not the communication device is in contact with the measurement subject during blood pressure measurement based on whether or not the electrical signal can be received. If the electrical signal can be received, it can be estimated that there is a high possibility that the person to be measured in the blood pressure data matches a specific user, so this communication device transmits this blood pressure data to the server. On the other hand, if the electrical signal cannot be received, it can be estimated that there is a high possibility that the person to be measured of the blood pressure data does not match the specific user, so this communication device does not transmit this blood pressure data to the server. Therefore, according to these blood pressure measurement devices and communication devices, it is possible to detect whether or not the blood pressure data represents the measurement result of the blood pressure of a specific user and prevent impersonation.

If so, the communication unit of the blood pressure measurement device does not transmit the blood pressure data to the communication device and the server.
