Description

INFORMATION PROCESSING APPARATUS, INFORMATION PROCESSING METHOD, AND INFORMATION PROCESSING PROGRAM

The present invention relates to an information processing apparatus, an information processing method, and an information processing program.

It is known that high blood pressure, for example, causes diseases at high risk of hospitalization or death such as stroke and myocardial infarction. For this reason, when taking out life insurance and medical insurance, the user is often required to report the blood pressure value (blood pressure value).

In addition, for example, some countries, local governments, companies, etc. have implemented a health promotion program that gives the user an incentive when the user improves the constitution of high blood pressure or maintains the blood pressure in a good state. The user is also required to report the blood pressure value when implementing such a program.

BACKGROUND In recent years, home-use or wearable-type sphygmomanometers capable of transmitting blood pressure values to the outside through the portable information terminal in cooperation with a portable information terminal such as a smartphone have been developed.
The insurance company or program operator can efficiently collect blood pressure values by having the user use the sphygmomanometer as described above.

There are various types of home-use or wearable-type sphygmomanometers, but one of them is detected by this pressure sensor in a state in which the pressure sensor is in direct contact with a living body site where arteries such as the radial artery of the wrist pass. There is known a tonometry-type sphygmomanometer capable of measuring biological information such as pulse and blood pressure using the information to be obtained (for example, see JP-A-2017-006672).

However, although using a home-use or wearable-type sphygmomanometer as described above makes it possible to declare the blood pressure value relatively easily, confirming that the declared blood pressure value is the user's own There is a problem of difficulty.

That is, a user who wants to fool insurance companies and obtain insurance under favorable conditions may measure the blood pressure values of others who are in good blood pressure. Similarly, a user attempting to steal incentives from a program operator may also measure the blood pressure values of others who are in good blood pressure. It is not easy to distinguish between the blood pressure value obtained by such spoofing and the true blood pressure value (the blood pressure value of the insured applicant).

The present invention, in one aspect, is made in view of such circumstances, and an object thereof is to provide a technology capable of confirming whether or not a declared blood pressure value is that of the person. It is.

The present invention adopts the following configuration in order to solve the problems described above.

Data that the user intends to declare as his own, first biometric information measured in a state associated with the data, and second user biometric information measured under the control of a credit institution, And a determination unit that determines whether the data belongs to the user based on the calculated matching rate, calculating the matching rate of the first biological information and the second biological information. .

In the above configuration, it can be confirmed whether or not the declared blood pressure value is that of the person.

According to the second aspect of the present invention, the storage device is further provided with a storage unit that stores the second biological information in association with the identification information of the user.

In the above configuration, it is possible to provide an information processing apparatus capable of appropriately managing information of a plurality of measured persons.

According to the third aspect of the present invention, the first biological information includes a first electrocardiographic waveform, and the second biological information includes a second electrocardiographic waveform.

According to the above configuration, it is possible to provide an information processing apparatus capable of securing the accuracy of personal authentication.

According to a fourth aspect of the present invention, the determination unit determines that the data belongs to the user when the coincidence rate between the first electrocardiogram waveform and the second electrocardiogram waveform exceeds a first threshold. It is determined that

According to a fifth aspect of the present invention, the first biological information includes a first electrocardiographic waveform and a first blood pressure waveform measured simultaneously, and the second biological information is a second cardiac radio wave measured simultaneously. And a second blood pressure waveform.

According to a sixth aspect of the present invention, the determination unit determines that the coincidence rate between the first electrocardiogram waveform and the second electrocardiogram waveform exceeds a first threshold and the first blood pressure waveform and the second blood pressure waveform. If the matching rate with the blood pressure waveform exceeds a second threshold, it is determined that the data is for the user.

According to the present invention, it is possible to provide a technology that can confirm whether or not the declared blood pressure value is the one of the person.

Hereinafter, an embodiment according to one aspect of the present invention (hereinafter, also referred to as “the present embodiment”) will be described based on the drawings. However, the embodiment described below is merely an illustration of the present invention in all respects. It goes without saying that various improvements and modifications can be made without departing from the scope of the present invention. That is, in the implementation of the present invention, a specific configuration according to the embodiment may be appropriately adopted. Although data appearing in the present embodiment is described in natural language, more specifically, it is specified by a pseudo language, a command, a parameter, a machine language or the like that can be recognized by a computer.

[Example of application]
First, an example of a scene to which the present invention is applied will be described with reference to FIG. FIG. 1 schematically illustrates an example of an information processing system including an information processing apparatus according to the present embodiment. The information processing system is assumed to be used, for example, for assessment of user's insurance participation, calculation of premium, performance evaluation of health promotion program, and the like.

Application configuration
Before describing the configuration of the information processing system, an overview of the information processing system will be described.
The information processing system includes an electrocardiographic waveform (biometric information) of a user (a person to be measured) and a confirmed electrocardiographic waveform under the management of a credit institution (for example, a medical institution), and a cardiac radio wave measured by a user terminal. Perform personal authentication by comparing the form. Here, authentication means "confirming an attribute based on an attribute that only the individual can have, and proving that the person is the individual". Moreover, personal identification means identifying at least an individual (including information indicating an individual) by the above authentication. Specifically, the personal authentication is performed from the user group (group consisting of a large number of users including user A) by confirming the attribute of user A and proving that the person to be authenticated is the user A himself. To identify that the target person is the user A. In addition, the electrocardiogram waveform is unique for each user, and can be used when performing personal authentication to ensure the accuracy of personal authentication.

As shown in FIG. 1, the information processing system includes a user terminal UT and an information processing apparatus IPE.

The user terminal UT measures the blood pressure value (data), the pulse rate (data) and the electrocardiogram waveform of the user (subject) and supplies the blood pressure value, the pulse rate and the electrocardiogram waveform to the information processing apparatus IPE. The user terminal UT is, for example, a watch-type wearable terminal. However, the user terminal UT is not limited to the watch-type wearable terminal, and may be appropriately selected according to the embodiment.

The information processing apparatus IPE includes a normalization unit IPEN, a table management unit IPET, and a determination unit IPEB.

The normalization unit IPEN normalizes the electrocardiogram based on the received electrocardiogram and the pulse rate.

The table management unit IPET stores, for each user, the blood pressure value supplied from the user terminal UT and the electrocardiogram waveform normalized by the normalization unit IPEN. The table management unit IPET stores a first measurement result (a normalized first electrocardiogram waveform) measured by the user terminal UT at least in a first period. Then, when the determination unit IPEB receives the second measurement result (blood pressure value and normalized second electrocardiogram waveform) measured by the user terminal UT in the second period, the determination unit IPEB and the normalized first electrocardiogram waveform Personal identification based on the normalized second electrocardiogram waveform. The determination unit IPEB is an example of the “determination unit” in the present invention.

The terminal that performs the first measurement and the terminal that performs the second measurement may be different from each other.

Application behavior
Next, an example of the personal authentication operation of the information processing system will be described.

Here, the case where the user intends to declare the blood pressure value measured by the second measurement as his own will be described. Therefore, the result of the first measurement (first electrocardiographic waveform) performed in the first period is treated as a reference value. The first electrocardiographic waveform is measured under the control of a credit institution. Then, the information processing system authenticates the second electrocardiographic waveform measured by the second measurement.

When performing authentication using an electrocardiogram waveform, the electrocardiogram waveform is normalized. Therefore, the normalization unit IPEN normalizes the first and second electrocardiogram waveforms. Specifically, the normalization unit IPEN normalizes the first electrocardiogram waveform based on the first pulse rate measured at the time of the first measurement. Furthermore, the normalization unit IPEN normalizes the first electrocardiogram waveform with respect to voltage amplitude. Also, the normalization unit IPEN normalizes the second electrocardiogram waveform based on the second pulse rate measured at the time of the second measurement. Furthermore, the normalization unit IPEN normalizes the second electrocardiogram waveform with respect to voltage amplitude.

When authenticating the second electrocardiogram waveform measured by the second measurement, the determination unit IPEB compares the normalized first electrocardiogram waveform with the normalized second electrocardiogram waveform, and performs a predetermined process. It is determined whether the condition is satisfied. Specifically, for example, the determination unit IPEB compares the shape of the normalized first electrocardiogram waveform with the shape of the normalized second electrocardiogram waveform, and calculates the coincidence rate (degree of coincidence) Do. The determination unit IPEB determines whether the matching rate exceeds a threshold. When it is determined that the matching rate exceeds the threshold value, the determining unit IPEB determines that the personal authentication is successful. When it is determined that the matching rate does not exceed the threshold, the determining unit IPEB determines that the personal authentication has failed. When it is determined that the personal identification has succeeded, the determination unit IPEB determines the blood pressure value measured by the second measurement as an authentic blood pressure value (blood pressure value of the user).

In addition, although the case where a user tries to declare the blood pressure value measured by the 2nd measurement as one's own thing was explained here, this may be not only a blood pressure value, but other measurement information.

[Effect of application example]
As described above, according to the information processing system according to the application example, personal authentication can be performed by using an electrocardiogram waveform. In the information processing system, since blood pressure values can be measured while performing personal identification, impersonation can be suppressed.

<1> First Embodiment A first embodiment according to the application example will be described below.

<1-1> Configuration <1-1-1> Information Processing System FIG. 2 is a block diagram showing an overall configuration of an information processing system including the information processing apparatus according to the first embodiment. As shown in FIG. 2, the information processing system includes, for example, a plurality of user terminals UT (in FIG. 2, UT1 to UTn, n is an arbitrary integer), a communication network NW, a server SV, and a plurality of doctor terminals DT (in FIG. 2). DT1 to DTm, m is an arbitrary integer). The user terminals UT1 to UTn, the server SV, and the doctor terminals DT1 to DTm can communicate with each other via the communication network NW. When the user terminals UT1 to UTn are not distinguished from one another, they are simply described as user terminals UT. Similarly, when the doctor terminals DT1 to DTm are not distinguished from one another, they are simply described as the doctor terminal DT. The server SV is an example of the “information processing apparatus IPE” in the application example.

<1-1-1-1> User Terminal As shown in FIG. 2, each of the user terminals UT1 to UTn includes sphygmomanometers BT1 to BTn and portable information terminals IT1 to ITn. When the sphygmomanometers BT1 to BTn are not distinguished from one another, they are simply described as the sphygmomanometer BT. Similarly, when the portable information terminals IT1 to ITn are not distinguished from one another, they are simply described as a portable information terminal IT.

<1-1-1-1-1> Blood Pressure Monitor Before describing the specific configuration of the blood pressure monitor BT, an outline of the blood pressure monitor BT will be described. The sphygmomanometer BT is, for example, a watch-type wearable terminal. The sphygmomanometer BT can simultaneously measure an electrocardiographic waveform (biological information) during blood pressure measurement. Specifically, the sphygmomanometer BT is attached to the wrist of a user (a person to be measured), and measures a blood pressure value and an electrocardiographic waveform at a user operation or at a preset timing or time interval. In addition, the sphygmomanometer BT can simultaneously measure the pulse rate during blood pressure measurement. The sphygmomanometer BT is, for example, a blood pressure value of the user, an electrocardiographic waveform of the user measured simultaneously with the blood pressure value, a pulse rate of the user measured simultaneously with the blood pressure value, the blood pressure value and the heart The measurement data in which the measurement date and time of the radio wave form, the model information (for example, model ID), and the user information (for example, user ID) are linked is transmitted to the portable information terminal IT by the wireless interface, for example. The model ID is an identifier indicating the model of the sphygmomanometer BT. The model ID is stored, for example, in the storage unit area. The user ID is an identifier assigned to each user. The sphygmomanometer BT is not limited to the type worn on the wrist, but may be a type in which the cuff is wound around the upper arm or the like or a stationary type. The sphygmomanometers BT1 to BTn may be different types of sphygmomanometers.

An example of a specific configuration of the sphygmomanometer BT will be described with reference to FIGS. 3 (a), 3 (b), and 4. FIG. 3 (a) is a schematic view showing a configuration example of the sphygmomanometer BT, and FIG. 3 (b) is a schematic view of the sphygmomanometer BT shown in FIG. 3 (a) viewed from A (direction D1). . FIG. 4 is a block diagram showing a configuration example of the sphygmomanometer BT.

As shown in FIGS. 3A and 3B, the sphygmomanometer BT includes a display area BT1, a strip BT2, a first electrode BT3, and a second electrode BT4.

The user wears the sphygmomanometer BT by winding the strip BT2 at a position (a measured portion) in which an artery (for example, a radial artery) to be subjected to blood pressure measurement is present and bringing the second electrode BT4 into contact with the user. . Then, the sphygmomanometer BT can measure the blood pressure value and the electrocardiographic waveform by bringing the finger of the arm different from the arm on which the sphygmomanometer BT is worn into contact with the first electrode BT3. Specifically, when the user wears the blood pressure monitor BT on the left hand, for example, the user brings the finger of the right hand into contact with the first electrode BT3. In the sphygmomanometer BT, when instructed to start measurement, a constant current is supplied between the first electrode BT3 and the second electrode BT4, and a current path is formed between the user's hands. As a result, a bioelectrical impedance, that is, a voltage is generated, which comprises the user's arm impedance. Therefore, the sphygmomanometer BT can measure the electrocardiogram waveform by measuring the voltage between the first electrode BT3 and the second electrode BT4. In addition, the sphygmomanometer BT can simultaneously measure a blood pressure value and an electrocardiographic waveform.

Next, a specific configuration of the sphygmomanometer BT will be described. As shown in FIG. 4, the sphygmomanometer BT includes a control unit 11, a communication unit 12, a storage unit 13, an operation unit 14, a display unit 15, an acceleration sensor 16, a living body sensor 17, and an environment sensor 18.

The control unit 11 includes, for example, a processor 11a and a memory 11b. The control unit 11 realizes various operation control, data processing, and the like by the processor 11a executing a program using the memory 11b. The processor 11a is, for example, a central processing unit (CPU) including an arithmetic circuit or a micro processing unit (MPU). The memory 11 b includes, for example, a non-volatile memory storing a program executed by the processor 11 a and a volatile memory such as a random access memory (RAM) used as a work memory. The control unit 11 has a clock (not shown) and can measure the current date and time. The processor 11a can execute control of each unit and data processing by executing a program stored in the memory 11b or the storage unit 13. That is, the processor 11a performs operation control of each unit according to the operation signal from the operation unit 14, and performs data processing on measurement data measured by the biological sensor 17 and the environment sensor 18.

The communication unit 12 is a communication interface for communicating with the portable information terminal IT. As the communication interface, for example, an interface adopting a short distance wireless data communication standard such as Bluetooth (registered trademark) is used. The communication unit 12 transmits data to the portable information terminal IT and receives data from the portable information terminal IT. Communication by the communication unit 12 may be either wireless communication or wired communication.

The storage unit 13 stores data of a program for controlling the sphygmomanometer BT, setting data for setting various functions of the sphygmomanometer BT, measurement data measured by the acceleration sensor 16, the biological sensor 17, and the environment sensor 18, and the like. Do. The storage unit 13 may be used as a work memory or the like when the program is executed.

The operation unit 14 detects an operation by the user, and outputs an operation signal indicating the content of the operation to the control unit 11. The operation unit 14 is not limited to the touch panel or the operation button. The operation unit 14 recognizes, for example, a voice recognition unit that recognizes a user's voice operation instruction, a biometric authentication unit that authenticates a part of the user's living body, and a user's expression or gesture from an image of the user's face or body. An image recognition unit or the like may be provided.

The display unit 15 includes, for example, a display screen (for example, an LCD (Liquid Crystal Display) or an EL (Electroluminescence) display), an indicator, and the like, and displays information in accordance with a control signal from the control unit 11.

The acceleration sensor 16 detects the acceleration received by the main body of the sphygmomanometer BT. For example, the acceleration sensor obtains acceleration data of three or six axes. The acceleration data can be used to estimate the amount of activity (posture and / or motion) of the user wearing the sphygmomanometer BT. The control unit 11 can associate the acceleration data measured by the acceleration sensor 16 with the measurement date and time based on the date and time information, and output it as measurement data.

The biometric sensor 17 measures biometric information of the user. The control unit 11 outputs measurement data linked to measurement date and time set based on date and time information to each data output from the biological sensor 17. The living body sensor 17 includes, for example, a blood pressure sensor 17a and an electrocardiogram sensor 17b. The blood pressure sensor 17a measures the blood pressure value of the user. The blood pressure sensor 17a can also measure the blood pressure waveform (biological information) of the user. The electrocardiogram sensor 17b measures the user's electrocardiogram waveform using the first electrode BT3 and the second electrode BT4 described with reference to FIGS. 3 (a) and 3 (b). Although not shown, the living body sensor 17 is provided with a pulse wave sensor that measures pulse wave data (pulse rate). The pulse wave sensor measures the pulse rate of the user.

Heart rate data, body temperature data, and the like are assumed as measurement data acquired by the biological sensor 17 in addition to blood pressure values and electrocardiogram waveforms, and a sensor for measuring these measurement data may be provided as the biological sensor 17. These measurement data may be output as measurement data of elements other than the blood pressure value and the electrocardiographic waveform.

The blood pressure sensor 17a is a continuous measurement or non-continuous measurement blood pressure sensor. The blood pressure sensor 17a is a blood pressure sensor capable of measuring values of blood pressure (for example, systolic blood pressure and diastolic blood pressure). The blood pressure sensor 17a may include, but is not limited to, a blood by pressure (BbB) blood pressure sensor that measures a blood pressure value for each heartbeat.

For example, as the blood pressure sensor 17a, a blood pressure sensor using an oscillometric method, a pulse transit time (PTT) method, a tonometry method, an optical method, a radio wave method, an ultrasonic method, or the like can be applied. The oscillometric method is a method of pressing the upper arm with a cuff and measuring a blood pressure value with a vibration waveform in the cuff. The PTT method is a method of measuring a pulse wave propagation time and estimating a blood pressure value from the measured pulse wave propagation time. The tonometry method is a method in which a pressure sensor is brought into direct contact with a living body site through which an artery such as a radial artery of the wrist passes and blood pressure values are measured using information detected by the pressure sensor. The optical method, the radio wave method, and the ultrasonic method are methods in which light, radio waves or ultrasonic waves are applied to blood vessels and blood pressure values are measured from the reflected waves.

The environmental sensor 18 includes a sensor that measures environmental information around the user and acquires the measured environmental data. In the configuration example shown in FIG. 4, the environment sensor 18 includes, for example, an air temperature sensor 18 a. However, the environment sensor 18 may include a sensor that measures temperature, humidity, sound, light, and the like in addition to the air temperature. The environment sensor 18 may include a sensor that measures information (environment data) of an environment assumed to be directly or indirectly related to the fluctuation of the blood pressure value. In addition, the control unit 11 can output the measurement data (environment data) by linking the measurement date and time to set the measurement data measured by the environment sensor 18 based on the date and time information.

The control unit 41 of the server SV develops the program stored in the storage unit 42 in the memory 41 b. Then, the control unit 41 causes the processor 41a to interpret and execute the program developed in the memory 41b to control each component. Thus, as shown in FIG. 8, the server SV according to the present embodiment includes a normalization unit 50 a, a normalization unit 50 b, a table management unit 51, an electrocardiogram determination unit 52, and a blood pressure output determination unit 53. Act as. The normalization unit 50a and the normalization unit 50b are examples of the "normalization unit IPEN" in the application example. The table management unit 51 is an example of the “table management unit IPET” in the application example. The electrocardiographic waveform determination unit 52 and the blood pressure output determination unit 53 are examples of the “determination unit IPEB” in the application example.

The normalization unit 50a receives an electrocardiographic waveform (reference electrocardiographic waveform) as a reference value and a pulse rate (reference pulse rate) related to the reference electrocardiographic waveform through the network NW. The reference electrocardiographic waveform is, for example, an electrocardiographic waveform that is confirmed by the doctor or the like as the electrocardiographic waveform of the user. The reference pulse rate is the pulse rate at the time of measurement of the reference electrocardiographic waveform. Then, the normalization unit 50a normalizes the reference electrocardiographic waveform based on the reference pulse rate. The normalized reference electrocardiogram is referred to as a normalized reference electrocardiogram.

The table management unit 51 includes a table for each user (person to be measured). By managing the table for each user, it becomes possible to properly manage information of a plurality of users. The table is expanded in, for example, the memory 41 b or the storage unit 42 of the server SV. The table receives and stores the normalized reference electrocardiogram waveform through the normalization unit 50a. In addition, the specific structural example of a table is mentioned later. The table management unit 51 enables display on the portable information terminal IT or the doctor terminal DT, for example, in accordance with a user's instruction via the portable information terminal IT or the doctor terminal DT.

The normalization unit 50b receives an electrocardiographic waveform for determination (electrocardiographic waveform for determination) and a pulse rate (pulse rate for determination) related to the electrocardiographic waveform for determination via the network NW. The determination electrocardiographic waveform is an electrocardiographic waveform used when the blood pressure value measured by the user himself is declared as the user's own. Moreover, the pulse rate for determination is a pulse rate at the time of measurement of an electrocardiographic waveform for determination. Then, the normalization unit 50b normalizes the determination electrocardiographic waveform based on the determination pulse rate. Note that the normalized determination electrocardiographic waveform is referred to as a normalized determination electrocardiographic waveform.

When the electrocardiographic waveform determination unit 52 receives the electrocardiogram waveform for normalization determination via the normalization unit 50b, the electrocardiographic waveform determination unit 52 performs a determination operation (personal identification operation) of the electrocardiogram waveform. The electrocardiographic waveform determination unit 52 compares the normalized reference electrocardiogram waveform stored in the table management unit 51 with the electrocardiographic waveform for normalization determination.

Specifically, the electrocardiogram waveform determination unit 52 determines whether the coincidence rate between the normalization determination electrocardiogram waveform and the normalization reference electrocardiogram waveform exceeds a first threshold. Any method may be used to determine the rate of coincidence between the normalized determination electrocardiographic waveform and the normalized reference electrocardiographic waveform.

The first threshold value is a value for determining that the normalized determination electrocardiogram waveform is a true electrocardiogram waveform. That is, if the coincidence rate exceeds the first threshold, it is determined that the electrocardiographic waveform for normalization determination and the normalized reference electrocardiographic waveform “match”, and if the coincidence rate does not exceed the first threshold, normalization is performed. It is determined that the determination electrocardiographic waveform and the normalized reference electrocardiographic waveform “do not match”. The first threshold is stored, for example, in the memory 41 b or the storage unit 42 of the server SV. Then, for example, the doctor can arbitrarily set the first threshold via the doctor terminal DT or the like.

Then, when the electrocardiographic waveform determination unit 52 performs an electrocardiographic waveform determination operation, the electrocardiographic waveform determination result (whether the normalized determination electrocardiographic waveform matches the normalized reference electrocardiographic waveform) is determined as a blood pressure output It supplies to the part 53.

The blood pressure output determination unit 53 receives the blood pressure value linked to the determination electrocardiographic waveform via the network NW. The blood pressure output determination unit 53 determines whether to output the blood pressure value based on the electrocardiographic waveform determination result supplied from the electrocardiogram waveform determination unit 52. If the electrocardiographic waveform determination result indicates that "the electrocardiographic waveform for normalization determination matches the normalized reference electrocardiographic waveform", the blood pressure output determination unit 53 indicates the meaning of "personal authentication success". Output the judgment result. Specifically, the blood pressure output determination unit 53 outputs, as a determination result, an authentication indicating that the received blood pressure value is an authentic blood pressure value and the received blood pressure value.

On the other hand, if the result of the electrocardiographic waveform determination means "matching that the electrocardiographic waveform for normalization determination does not match the normalization reference electrocardiographic waveform", the blood pressure output determining unit 53 determines that "personal authentication failure" Output the judgment result indicating the meaning of Specifically, the blood pressure output determination unit 53 outputs a notification that the blood pressure value is not a true blood pressure value or an error notification.

The determination result is supplied to, for example, a company that performs insurance assessment of the user, calculation of a premium, performance evaluation of a health promotion program, and the like. More specifically, when the company or the like receives an authentication that the blood pressure value is an authentic blood pressure value as the determination result, the blood pressure value associated with the authentication is an authentic blood pressure value. It can be judged. As a result, according to the determination result, the company or the like can easily determine which of the blood pressure value received from the server SV is obtained by spoofing and the true blood pressure value (the blood pressure value of the insurance applicant). Can be distinguished.

<1-1-3> Example of Structure of Table Next, an example of the structure of the table will be described with reference to FIG. FIG. 9 is a diagram showing an example of the structure of the table. For simplicity, the structure of the table will be described focusing on one user.

As shown in FIG. 9, the table stores, for example, measurement date and time, model information (for example, model ID), and a normalized reference electrocardiogram waveform for each user information (for example, user ID) included in the measurement data.

For example, the table management unit 51 can output a corresponding normalized reference electrocardiogram from the user ID, the measurement date, the model ID, or the like.

Note that the user ID and the model ID are configured by any combination of numbers and characters. The normalized reference electrocardiographic waveform is, for example, a waveform with time on the horizontal axis and an output voltage on the vertical axis. Further, the length of the normalized reference electrocardiogram may be any length as long as there is a necessary minimum length of waveforms that can be compared.

<1-2> Operation <1-2-1> Electrocardiogram Waveform Storage Operation Next, using FIG. 10, an example of the electrocardiogram waveform storage operation of the information processing system including the information processing apparatus according to the first embodiment will be described. Do. FIG. 10 is a flowchart illustrating an example of the processing procedure of the information processing system. In addition, the process sequence demonstrated below is only an example, and each process may be changed as much as possible. In addition, according to the embodiment, steps may be omitted, replaced, or added as appropriate, according to the embodiment.

[Step S101]
The sphygmomanometer BT measures an electrocardiographic waveform of a user (a subject) with the electrocardiographic sensor 17b. Then, the control unit 11 generates measurement data in which the electrocardiogram waveform is linked to the measurement date and time, the user ID, and the model ID, and supplies the measurement data to the portable information terminal IT via the communication unit 12.

When receiving the measurement data from the sphygmomanometer BT at the communication unit 23, the portable information terminal IT transfers the measurement data to the doctor terminal DT via the network NW at any timing.

The measurement of the electrocardiogram waveform in step S101 does not necessarily have to be measured by the sphygmomanometer BT. For example, an electrocardiographic waveform may be measured by an electrocardiograph installed in a medical institution. In this case, the electrocardiograph transfers measurement data (measurement date, user ID, model ID, and electrocardiogram waveform) to the doctor terminal DT.

[Step S102]
For example, the doctor confirms whether the electrocardiogram waveform transferred to the doctor terminal DT is the user's own electrocardiogram waveform.

For example, by measuring an electrocardiogram waveform before the user sees a doctor, the doctor can confirm that the measured electrocardiogram waveform is the user's own electrocardiogram waveform.

If the doctor can not confirm that the electrocardiogram waveform transferred to the doctor terminal DT is the user's own electrocardiogram waveform, the doctor discards the electrocardiogram waveform (step S102, NO).

[Step S103]
If the doctor confirms that the electrocardiogram waveform transferred to the doctor terminal DT is the user's own electrocardiogram waveform (YES in step S102), the confirmed electrocardiogram waveform is used as the reference electrocardiogram waveform from the doctor terminal DT , To the server SV. At this time, the reference pulse rate is also transmitted from the doctor terminal DT to the server SV together with the reference electrocardiographic waveform.

[Step S104]
The normalization unit 50a receives the reference electrocardiographic waveform and the reference pulse rate via the network NW. Then, the normalization unit 50a normalizes the reference electrocardiographic waveform based on the reference pulse rate.

[Step S105]
The table management unit 51 stores the measurement date and time, the model ID, and the normalized reference electrocardiogram waveform in the table based on the user ID.

<1-2-2> Personal Authentication Operation Next, an example of the personal authentication operation of the information processing system including the information processing apparatus according to the first embodiment will be described with reference to FIG. FIG. 11 is a flowchart illustrating an example of the processing procedure of the information processing system. In addition, the process sequence demonstrated below is only an example, and each process may be changed as much as possible. In addition, according to the embodiment, steps may be omitted, replaced, or added as appropriate, according to the embodiment.

[Step S110]
The control unit 41 (electrocardiographic waveform determination unit 52) of the server SV determines whether to perform the personal authentication operation. The instruction as to whether or not to perform the personal identification operation is received from, for example, the portable information terminal IT or the doctor terminal DT.

For example, when an insurance company etc. performs, for example, a user's insurance participation assessment, calculation of a premium, performance evaluation of a health promotion program, etc., a personal identification operation is performed.

[Step S111]
If it is determined that the personal authentication operation is to be performed (YES in step S110), the electrocardiographic waveform determination unit 52 determines whether the normalized reference electrocardiogram waveform is stored in the table. If the electrocardiographic waveform determination unit 52 determines that the normalized reference electrocardiographic waveform is not stored in the table (step S111, NO), it cancels the personal identification operation.

[Step S112]
If the electrocardiographic waveform determination unit 52 determines that the normalized reference electrocardiographic waveform is stored in the table (YES in step S111), the electrocardiographic waveform determination unit 52 performs a personal authentication operation.

Specifically, the user measures the blood pressure value and the electrocardiographic waveform using the sphygmomanometer BT. Then, the sphygmomanometer BT transmits a blood pressure value, an electrocardiographic waveform for determination, and a pulse rate for determination to the server SV.
The blood pressure value, the determination electrocardiographic waveform, and the determination pulse rate are linked to one another.

Then, the normalization unit 50b receives the electrocardiographic waveform for determination and the pulse rate for determination via the network NW. The normalization unit 50b normalizes the determination electrocardiographic waveform based on the determination pulse rate.

Then, the electrocardiogram waveform determination unit 52 determines whether the coincidence rate between the normalization determination electrocardiogram waveform and the normalization reference electrocardiogram waveform exceeds a first threshold.

[Step S113]
When the electrocardiographic waveform determination unit 52 determines that the coincidence rate between the normalized determination electrocardiogram waveform and the normalized reference electrocardiographic waveform exceeds the first threshold (YES in step S112), the determination electrocardiographic waveform is , It is determined that the user's ECG waveform. Then, the electrocardiographic waveform determination unit 52 supplies the electrocardiographic waveform determination result to the blood pressure output determination unit 53.

When receiving the electrocardiographic waveform determination result that the determination electrocardiogram waveform is the user's electrocardiogram waveform, the blood pressure output determination unit 53 outputs a determination result indicating the meaning of “personal authentication success”. Thus, the personal identification operation is completed.

This ensures that the blood pressure value measured by the sphygmomanometer BT is the user's blood pressure. Therefore, based on the blood pressure value measured by the sphygmomanometer BT, the insurance company or the like can perform, for example, the user's insurance participation assessment, calculation of the premium, performance evaluation of the health promotion program, and the like.

[Step S114]
When the electrocardiographic waveform determination unit 52 determines that the coincidence rate between the normalized determination electrocardiogram waveform and the normalized reference electrocardiographic waveform does not exceed the first threshold (step S112, NO), the determination electrocardiographic waveform is , It is determined that the user's ECG waveform is not. Then, the electrocardiographic waveform determination unit 52 supplies the electrocardiographic waveform determination result to the blood pressure output determination unit 53.

When receiving the electrocardiographic waveform determination result that the electrocardiographic waveform for determination is not the user's electrocardiogram waveform, the blood pressure output determination unit 53 outputs a determination result indicating the meaning of “personal authentication failure”. Thus, the personal identification operation is completed.

This ensures that the blood pressure value measured by the sphygmomanometer BT is not the user's blood pressure. Therefore, the insurance company can detect or prevent the impersonation of the user.

<1-3> Effects According to the above-described embodiment, the electrocardiographic waveform of the user (person to be measured) and the normalized reference electrocardiographic waveform confirmed are stored in the table. Then, the user (the subject) measures the electrocardiographic waveform (determination electrocardiographic waveform) at the same time as measuring the blood pressure value. Then, the information processing apparatus performs personal authentication by determining whether or not the normalized reference electrocardiogram waveform and the normalized determination electrocardiogram waveform satisfy predetermined conditions. Specifically, the information processing apparatus determines whether the matching rate between the normalized reference electrocardiogram waveform and the normalized determination electrocardiogram waveform exceeds a first value. Then, when the information processing apparatus determines that the normalized reference electrocardiographic waveform and the normalized determination electrocardiographic waveform satisfy predetermined conditions, the information processing apparatus determines that the measured blood pressure value is an authentic blood pressure value. Can. On the other hand, when the information processing apparatus determines that the normalized reference electrocardiogram waveform and the normalized determination electrocardiographic waveform do not satisfy the predetermined conditions, the information processing device determines that the measured blood pressure value is not an authentic blood pressure value. be able to.

The electrocardiogram is unique for each user. Therefore, the information processing apparatus can secure the accuracy of the personal authentication by comparing the electrocardiogram waveforms based on the electrocardiogram waveform confirmed by the doctor or the like as the user's electrocardiogram waveform.

Therefore, according to the information processing system including the information processing apparatus according to the embodiment described above, it can be confirmed whether or not the declared blood pressure value is that of the person.

FIG. 12 is a block diagram schematically illustrating an example of a functional configuration of the server SV according to the present embodiment.

The control unit 41 of the server SV develops the program stored in the storage unit 42 in the memory 41 b. Then, the control unit 41 causes the processor 41a to interpret and execute the program developed in the memory 41b to control each component. Thus, as shown in FIG. 12, the server SV according to the present embodiment includes the normalization unit 50a, the normalization unit 50b, the normalization unit 50c, the normalization unit 50d, the table management unit 51-1, and the waveform determination unit 54. , And functions as a computer including the blood pressure output determination unit 53-1. The normalization unit 50a, the normalization unit 50b, the normalization unit 50c, and the normalization unit 50d are examples of the "normalization unit IPEN" in the application example. The table management unit 51-1 is an example of the “table management unit IPET” in the application example. The waveform determination unit 54 and the blood pressure output determination unit 53-1 are examples of the “determination unit IPEB” in the application example.

The normalization unit 50a receives the reference electrocardiogram waveform and the pulse rate (first reference pulse rate) related to the reference electrocardiogram waveform through the network NW. The first reference pulse rate is the pulse rate at the time of measurement of the reference electrocardiographic waveform. Then, the normalization unit 50a normalizes the reference electrocardiographic waveform based on the first reference pulse rate.

The normalization unit 50c receives a blood pressure waveform (reference blood pressure waveform) as a reference value and a pulse rate (second reference pulse rate) related to the reference blood pressure waveform via the network NW. The reference blood pressure waveform is, for example, a blood pressure waveform that is confirmed by the doctor or the like as the blood pressure waveform of the user.
The second reference pulse rate is the pulse rate at the time of measurement of the reference blood pressure waveform. Then, the normalization unit 50c normalizes the reference blood pressure waveform based on the second reference pulse rate. The normalized reference blood pressure waveform is referred to as a normalized reference blood pressure waveform. When the reference electrocardiographic waveform and the reference blood pressure waveform are simultaneously measured, the first reference pulse rate and the second reference pulse rate are the same.

The table management unit 51-1 has a table for each user (person to be measured). By managing the table for each user, it becomes possible to properly manage information of a plurality of users.
The table is expanded in, for example, the memory 41 b or the storage unit 42 of the server SV. The table receives and stores the normalized reference electrocardiographic waveform via the normalization unit 50a, and further receives and stores the normalized reference blood pressure waveform via the normalization unit 50c. In addition, the specific structural example of a table is mentioned later. The table management unit 51-1 enables display on the portable information terminal IT or the doctor terminal DT, for example, according to a user's instruction via the portable information terminal IT or the doctor terminal DT.

The normalization unit 50b receives the determination electrocardiographic waveform and the pulse rate (first determination pulse rate) related to the determination electrocardiographic waveform via the network NW. The first determination pulse rate is the pulse rate at the time of measurement of the determination electrocardiographic waveform. Then, the normalization unit 50b normalizes the determination electrocardiographic waveform based on the first determination pulse rate.

The normalization unit 50d receives the blood pressure waveform for determination (blood pressure waveform for determination) and the pulse rate (second pulse rate for determination) related to the blood pressure waveform for determination via the network NW.

The second determination pulse rate is a pulse rate at the time of measurement of the determination blood pressure waveform. Then, the normalization unit 50d normalizes the blood pressure waveform for determination based on the second determination pulse rate. The normalized blood pressure waveform for determination is referred to as a normalized blood pressure waveform for determination. When the determination electrocardiographic waveform and the determination blood pressure waveform are simultaneously measured, the first determination pulse rate and the second determination pulse rate are the same.

The waveform determination unit 54 receives the electrocardiographic waveform for normalization determination via the normalization unit 50b, and further receives the blood pressure waveform for normalization determination via the normalization unit 50d. The determination operation (personal identification operation) is performed. The waveform determination unit 54 compares the normalized reference electrocardiogram waveform stored in the table management unit 51-1 with the normalized determination electrocardiogram waveform, and the normal stored in the table management unit 51-1. The normalized reference blood pressure waveform and the normalized judgment blood pressure waveform are compared. Then, the waveform determination unit 54 supplies the waveform determination result to the blood pressure output determination unit 53-1 as the comparison result.

Specifically, the waveform determination unit 54 determines whether the coincidence rate between the normalization determination electrocardiogram waveform and the normalization reference electrocardiogram waveform exceeds a first threshold. Any method may be used to determine the rate of coincidence between the normalized determination electrocardiographic waveform and the normalized reference electrocardiographic waveform.

Any method may be used as a method of determining the matching rate between the normalized blood pressure waveform for normalization determination and the normalized reference blood pressure waveform.

The second threshold is a value for determining that the blood pressure waveform for normalization determination is a true blood pressure waveform. That is, when the coincidence rate exceeds the second threshold, the blood pressure waveform for normalization determination and the normalized reference blood pressure waveform are determined to “match”, and when the coincidence rate does not exceed the second threshold, normalization determination It is determined that the reference blood pressure waveform and the normalized reference blood pressure waveform do not match. The second threshold is stored, for example, in the memory 41 b or the storage unit 42 of the server SV. Then, for example, the doctor can arbitrarily set the second threshold via the doctor terminal DT or the like.

Then, when the waveform determination unit 54 performs the determination operation of the electrocardiogram waveform and the blood pressure waveform, the electrocardiographic waveform determination result (whether or not the normalized determination electrocardiographic waveform matches the normalized reference electrocardiographic waveform) is output as a blood pressure output. The information is supplied to the determination unit 53.

The blood pressure output determination unit 53-1 receives, via the network NW, a determination electrocardiographic waveform and a blood pressure value associated with the determination blood pressure waveform. The blood pressure output determination unit 53-1 determines whether to output the blood pressure value based on the waveform determination result supplied from the waveform determination unit 54.

On the other hand, the result of the waveform determination means that "the ECG waveform for normalization determination does not match the normalization reference ECG waveform, or the blood pressure waveform for normalization determination does not match the normalization reference blood pressure waveform". In the case, the blood pressure output determination unit 53-1 outputs a determination result indicating the meaning of “personal authentication failure”. Specifically, the blood pressure output determination unit 53-1 outputs a notification that the blood pressure value is not a true blood pressure value or an error notification.

The determination result is supplied to, for example, a company that performs insurance assessment of the user, calculation of a premium, performance evaluation of a health promotion program, and the like.

At the same time, the electrocardiographic waveform of the user is measured by the electrocardiogram sensor 17b, and the blood pressure waveform of the user is measured by the blood pressure sensor 17a. Then, the control unit 11 generates measurement data in which the measured blood pressure value and the blood pressure waveform and the electrocardiogram waveform thereof are linked to the measurement date, user ID, and model ID, and the portable information terminal via the communication unit 12 Supply to IT.

The measurement of the electrocardiogram waveform and the blood pressure waveform in step S201 does not necessarily have to be measured by the sphygmomanometer BT. For example, it may be measured by an electrocardiograph or a sphygmomanometer installed in a medical institution.

The instruction as to whether or not to perform the personal identification operation is received from, for example, the portable information terminal IT or the doctor terminal DT.

[Step S211]
If it is determined that the personal identification operation is to be performed (YES in step S210), the waveform determination unit 54 determines whether the normalized reference electrocardiogram waveform and the normalized reference blood pressure waveform are stored in the table. When determining that the normalized reference electrocardiogram waveform and the normalized reference blood pressure waveform are not stored in the table (step S211, NO), the waveform determination unit 54 cancels the personal identification operation.

When the waveform determination unit 54 determines that the normalized reference electrocardiogram waveform and the normalized reference blood pressure waveform are stored in the table (YES in step S211), the waveform determination unit 54 performs an operation of determining an electrocardiogram waveform.

Specifically, the user uses the sphygmomanometer BT to measure a blood pressure value, an electrocardiogram waveform, a blood pressure waveform, a first determination pulse rate, and a second determination pulse rate. Then, the sphygmomanometer BT transmits the blood pressure value, the determination electrocardiographic waveform, the determination blood pressure waveform, the first determination pulse rate, and the second determination pulse rate to the server SV. The blood pressure value, the cardiogram for determination, the blood pressure waveform for determination, the first determination pulse rate, and the second determination pulse rate are mutually linked.

Then, the normalization unit 50b receives the electrocardiographic waveform for determination and the first pulse rate for determination via the network NW. The normalization unit 50b normalizes the determination electrocardiographic waveform based on the first determination pulse rate.

Furthermore, the normalization unit 50d receives the blood pressure waveform for determination and the second pulse rate for determination via the network NW. The normalization unit 50d normalizes the blood pressure waveform for determination based on the second determination pulse rate.

The waveform determination unit 54 determines the coincidence rate between the normalized determination electrocardiogram waveform and the normalized reference electrocardiogram waveform. Any method may be used to determine the rate of coincidence between the normalized determination electrocardiographic waveform and the normalized reference electrocardiographic waveform. Then, the waveform determination unit 54 determines whether the coincidence rate between the normalization determination electrocardiogram waveform and the normalization reference electrocardiogram waveform exceeds a first threshold.

[Step S213]
When the waveform determination unit 54 determines that the coincidence rate between the normalized determination electrocardiogram waveform and the normalized reference electrocardiogram waveform exceeds the first threshold (YES in step S212), the normalized determination electrocardiogram waveform is It is determined that the waveform is an electrocardiogram of the user. Then, the waveform determination unit 54 performs a blood pressure waveform determination operation.

The waveform determination unit 54 determines whether the matching rate between the normalized determination blood pressure waveform and the normalized reference blood pressure waveform exceeds a second threshold.

[Step S214]
When the waveform determination unit 54 determines that the matching rate between the normalized determination blood pressure waveform and the normalized reference blood pressure waveform exceeds the second threshold (YES in step S213), the determination blood pressure waveform is determined by the user. It determines that it is a blood pressure waveform. Then, the waveform determination unit 54 supplies the waveform determination result to the blood pressure output determination unit 53-1.

The blood pressure output determination unit 53-1 indicates the meaning of "personal authentication success" when receiving the waveform determination result that the determination electrocardiographic waveform is the user's electrocardiographic waveform and the determination blood pressure waveform is the user's blood pressure waveform. Output the judgment result. Thus, the personal identification operation is completed.

[Step S215]
If the waveform determination unit 54 determines that the coincidence rate between the normalized determination electrocardiogram waveform and the normalized reference electrocardiogram waveform does not exceed the first threshold (step S212, NO), the determination electrocardiogram waveform is a user It is determined that it is not an electrocardiogram waveform of When the waveform determination unit 54 determines that the matching rate between the determination blood pressure waveform and the reference blood pressure waveform does not exceed the second threshold (step S213, NO), the determination blood pressure waveform is the user's blood pressure waveform It is not determined. Then, the waveform determination unit 54 supplies the waveform determination result to the blood pressure output determination unit 53-1.

The blood pressure output judging unit 53-1 outputs the judgment result indicating the meaning of “personal authentication failure” when receiving the judgment result that the judgment electrocardiographic waveform or the judgment blood pressure waveform is not the user's electrocardiographic waveform. Thus, the personal identification operation is completed.

This ensures that the blood pressure value measured by the sphygmomanometer BT is not the user's blood pressure. Therefore, the insurance company can prevent the detection or impersonation of impersonation.

The execution order of step S212 and step S213 may be interchanged.

<2-3> Effects According to the above-described embodiment, the normalized reference electrocardiographic waveform confirmed as the electrocardiographic waveform of the user (subject) and the normal confirmed as the blood pressure waveform of the user (subject) The reference blood pressure waveform is stored in the table. Then, the user (person to be measured) measures an electrocardiographic waveform (determination electrocardiographic waveform) and a blood pressure waveform (determination blood pressure waveform) simultaneously with measuring the blood pressure value. Then, in the information processing apparatus, the normalized reference electrocardiographic waveform and the normalized determination electrocardiographic waveform satisfy predetermined conditions, and the normalized reference blood pressure waveform and the normalized determination blood pressure waveform have predetermined conditions. Personal authentication is performed by determining whether the user is satisfied. Specifically, the information processing apparatus determines whether the matching rate between the normalized reference electrocardiogram waveform and the normalized determination electrocardiogram waveform exceeds a first value. Furthermore, the information processing apparatus determines whether the matching rate between the normalized reference blood pressure waveform and the normalized determination blood pressure waveform exceeds a second value. Then, in the information processing apparatus, the normalized reference electrocardiographic waveform and the normalized determination electrocardiographic waveform satisfy predetermined conditions, and the normalized reference blood pressure waveform and the normalized determination blood pressure waveform have predetermined conditions. When it is determined to be satisfactory, it can be determined that the measured blood pressure value is a true blood pressure value. On the other hand, in the information processing apparatus, the normalized reference electrocardiographic waveform and the normalized determination electrocardiographic waveform do not satisfy predetermined conditions, or the normalized reference blood pressure waveform and the normalized determination blood pressure waveform have predetermined conditions It can be determined that the measured blood pressure value is not an authentic blood pressure value.

The blood pressure waveform is unique for each user. Therefore, the information processing apparatus further secures the accuracy of the personal authentication in comparison with the first embodiment by comparing the blood pressure waveform based on the blood pressure waveform confirmed to be the user's blood pressure waveform by the doctor or the like. Is possible.

Therefore, according to the information processing system including the information processing apparatus according to the embodiment described above, it is possible to confirm whether the declared blood pressure value is the one of the person or not, as in the first embodiment.
