Description

  The present invention relates to a technique for managing biological information of a measurement subject.

  Various biological information measuring devices such as a weight scale, a body fat scale, and a blood pressure monitor have a function of identifying who the user is by performing authentication using a fingerprint and managing the measurement result for each user. Some are implemented.

However, when fingerprints are used as authentication information, for example, when a finger is injured or has scratches or dirt, the collected fingerprint does not match the registered fingerprint. In some cases, the biometric information measuring apparatus cannot be authenticated even by a user. In this way, when authentication is performed based on biometric information that is a biometric feature of human beings, even if the user is the same person, differences in health and physical conditions between biometric information registration and authentication Therefore, the biometric information changes, and therefore, authentication may be mistaken and user management may not be performed correctly. Therefore, Patent Document 1 discloses a technique for performing authentication using an authentication means other than biological information, such as an IC card or a personal identification number, as a measure for when authentication is incorrect.
JP 2000-200113 A

  However, in the technique described in Patent Document 1, if the authentication method requires an article such as an IC card, the user must always carry it and manage it so that it cannot be stolen by a third party. Don't be. In addition, if the method requires a personal identification number, the user must store it correctly. Therefore, whichever method is adopted, the burden imposed on the user is large.

  This invention is made | formed in view of this situation, The objective is to manage biometric information correctly for every user, without imposing a burden on a to-be-measured person.

To achieve the above object, the present invention obtains the user identification information of each user, a biometric information storage means for storing in association with the biometric information of each user, the biometric information of the measured person vivo An information acquisition means; a similarity calculation means for calculating a similarity between the biological information acquired by the biological information acquisition means and the biological information stored in the biological information storage means; and the calculated similarity is a threshold value. The user identification information can be specified by the specifying means for specifying the biometric information exceeding and specifying the user identification information stored in the biometric information storage means in association with the specified biometric information. The biometric information acquired by the biometric information acquisition means is stored in the biometric information storage means in association with the specified user identification information, and the specifying means If the user identification information cannot be specified, the biological information acquired by the biological information acquisition unit is stored in the biological information storage unit in association with the newly generated provisional user identification information. There is provided a biological information management device comprising a storage control means.
Thereby, biometric information can be correctly managed for every user, without imposing a burden on a to-be-measured person.

In a preferred aspect of the present invention, the user identification information specified by the specifying unit is notified to the measurement subject, and the biological information acquired by the biological information acquisition unit is stored in association with the notified user identification information. A first question means for asking the subject whether or not it is acceptable, and the storage control means responds that the biometric information may be stored in response to the question by the first question means May be stored in the biological information storage unit in association with the notified user identification information, the biological information acquired by the biological information acquisition unit.

Next, the best mode for carrying out the present invention will be described.
In the description of this embodiment, a person whose biological information is measured by the biological information measurement management device is referred to as a “measured person”. Among the measured persons, in particular, a regular measured person registered in advance in the biological information measurement management device is referred to as a “registered user”, and an unregistered measured person is referred to as a “provisional user”. Call.

(A) Configuration of Embodiment FIG. 1 is a perspective view showing an overview of a blood pressure measurement management device 1 according to an embodiment of the present invention.
The blood pressure measurement management device 1 is a blood pressure / pulse meter having a pulse wave detection function, and is a biological information measurement management device that measures and manages blood pressure values and pulse rates, which are biological information of the measurement subject. When the measurement subject wants to measure the blood pressure value and the pulse rate, first, the fingerprint is read by bringing the fingertip into contact with the fingerprint reading device 18. After logging in to the blood pressure measurement management device 1 through authentication by fingerprint, the measurement subject wraps the cuff 171 around the upper arm and presses a predetermined button on the operation unit 14 to instruct start of measurement. In response to this instruction, the blood pressure measurement management device 1 detects a change in blood pressure synchronized with the heartbeat of the user while gradually removing the air after filling the cuff 171 with an air pump 172 in the device described later. The blood pressure value and the pulse rate are measured based on the detection result. The blood pressure measurement management device 1 stores the blood pressure value and the pulse rate obtained by this measurement, and displays them on the display unit 15 that is a liquid crystal display.

(A-1) Configuration of Blood Pressure Measurement Management Device 1 Next, FIG. 2 is a block diagram showing the configuration of the blood pressure measurement management device 1.
As shown in FIG. 2, the blood pressure measurement management device 1 includes a CPU (Central Processing Unit) 11, a ROM (Read Only Memory) 12, a RAM (Random Access Memory) 13, an operation unit 14, a display unit 15, A storage unit 16, a measurement unit 17, and a fingerprint reading device 18. The CPU 11 controls the entire apparatus by performing arithmetic processing in accordance with procedures described in various control programs stored in the ROM 12 using the RAM 13 as a work work area. The operation unit 14 includes various keys and outputs a signal corresponding to the pressed key to the CPU 11. The display unit 15 is a liquid crystal display, and displays a menu screen for operating the blood pressure measurement management device 1 and an interactive screen for asking questions to the subject under the control of the CPU 11 in addition to the measurement results described above. To do.

  The measurement unit 17 includes a pressure sensor 173, a pulse wave detection sensor 174, a blood pressure calculation unit 175, and a pulse rate calculation unit 176 in addition to the cuff 171 and the air pump 172 described above, and the blood pressure of the measurement subject. The value and the pulse rate are measured, and the measurement result is output to the CPU 11. The air pump 172 expands or contracts the cuff 171 by filling the cuff 171 with air or drawing air from the cuff 171. The pressure sensor 173 detects the internal pressure of the cuff 171 that changes according to the measurement subject's pulse. The pulse wave detection sensor 174 is, for example, a photoelectric sensor or a piezoelectric element, and detects the pulse wave of the measurement subject. Based on the pressure detected by the pressure sensor 173 and the pulse wave detected by the pulse wave detection sensor 174, the blood pressure calculation unit 175 performs a systolic blood pressure value (hereinafter referred to as “upper blood pressure value”) and a diastole. A blood pressure value (hereinafter referred to as “lower blood pressure value”) is calculated. In the following, when simply referred to as “blood pressure value”, it means these “upper blood pressure value” and “lower blood pressure value”. The pulse rate calculation unit 176 counts the wave number per predetermined time of the pulse wave detected by the pulse wave detection sensor 174, and calculates this as “heart rate”. Thus, the measurement unit 17 measures the “upper blood pressure value”, the “lower blood pressure value”, and the “pulse rate” as the biological information of the measurement subject.

  The fingerprint reading device 18 reads the fingerprint of the person to be measured and supplies fingerprint data representing the fingerprint (or a hash value corresponding to the fingerprint data) to the CPU 11 as authentication information for authenticating the person to be measured. That is, the fingerprint reading device 18 is an input unit for inputting authentication information. The CPU 11 performs authentication by collating the authentication information (fingerprint data) supplied from the fingerprint reading device 18 with the fingerprint data of the registered user stored in advance as authentication information in the storage unit 16, and the subject to be measured Whether the user is a registered user or the registered user when the subject is a registered user.

  The storage unit 16 is a non-volatile storage unit such as a flash memory, for example, fingerprint data collected in advance as authentication information from a registered user, an authentication information management table 161, a registered user biometric information management table 162, and a provisional user biometric. An information management table 163 is stored. The registered user biometric information management table 162 and the provisional user biometric information management table 163 are means for storing (storing) the biometric information of the measurement subject.

(A-2) Configuration of Authentication Information Management Table 161 FIG. 3 is a diagram showing an example of the contents of the authentication information management table 161.
As shown in FIG. 3, in the authentication information management table 161, “registered user ID” and “fingerprint ID” are described in association with each other. “Registered user ID” is user identification information assigned to each registered user by the CPU 11. The aforementioned “registered user” is a user to whom this “registered user ID” is assigned. “Fingerprint ID” is identification information assigned by the CPU 11 to fingerprint data representing the fingerprint of each registered user. Hereinafter, the registered user to which the registered user ID “UID-A” in the figure is assigned is referred to as “registered user A”, and the fingerprint ID of the fingerprint data is referred to as “fingerprint A”. Similarly, the registered user to which the registered user ID “UID-B” is assigned is called “registered user B”, and the fingerprint ID of the fingerprint data is “fingerprint B”. Furthermore, the registered user ID “UID-C” The registered user to which is assigned is called “registered user C”, and the fingerprint ID of the fingerprint data is “fingerprint C”. The fingerprint data as the authentication information is read by the fingerprint reading device 18 at the time of fingerprint registration, and is stored in the storage unit 16 in association with the fingerprint ID by the CPU 11.

(A-3) Configuration of Registered User Biometric Information Management Table 162 Next, FIG. 4 is a diagram showing an example of the contents of the registered user biometric information management table 162.
As shown in FIG. 4, in the registered user biometric information management table 162, “registered user ID” and “measurement result” are described in association with each other. “Registered user ID” is user identification information assigned to a registered user, as described above. “Measurement result” is a numerical value indicating the measurement result of the biological information (“upper blood pressure value”, “lower blood pressure value”, and “pulse rate”) of each measurement item of the measurement subject who is a registered user. As shown in FIG. 4, these are associated with “measurement date and time”. The measurement date and time represents the date and time when the biological information was measured, but the illustration and description of the measurement time are omitted. In the figure, the measurement results are shown in time series according to the measurement date and time. When the biological information is measured by the measurement unit 17, the CPU 11 writes the biological information separately for each registered user in the corresponding field of the registered user biological information management table 162.

  In the example of FIG. 4, the upper blood pressure value “130” and the lower blood pressure value “70” are associated with the registered user ID “UID-A” as the measurement result of the biological information of the measurement date “2007/4/15”. ”, The pulse rate“ 75 ”is described, and as the measurement result of the measurement date“ 2007/7/18 ”, the upper blood pressure value“ 135 ”, the lower blood pressure value“ 72 ”, and the pulse rate“ 85 ”are described, As the measurement result of the measurement date “2007/8/8”, the upper blood pressure value “130”, the lower blood pressure value “72”, and the pulse rate “79” are described, and the measurement date “2007/8/23” is measured. As a result, the measurement result of the biological information is sequentially written along the measurement date and time such that the upper blood pressure value “127”, the lower blood pressure value “65”, and the pulse rate “73” are described. Here, the measurement date “2007/8/23” is the latest measurement result, and the field on the right side is blank. Similarly, in other registered user IDs “UID-B”, “UID-C”..., The measurement date and time and the measurement result of the biological information are written in association with each other.

(A-4) Configuration of Provisional User Biometric Information Management Table 163 Next, FIG. 5 is a diagram illustrating an example of the contents of the provisional user biometric information management table 163.
As shown in FIG. 5, “temporary user ID” and “measurement result” are written in association with each other in the provisional user biometric information management table 163. The “temporary user ID” is assigned to the above-described temporary user, that is, a new user for which the registered user ID is not written in the authentication information management table 161. As with the registered user biometric information management table 162, the “measurement result” includes the measurement result (“upper blood pressure value”, “lower blood pressure value”, and “pulse rate”) of each measurement item of the temporary user, and the measurement thereof. Date and time.

  In the example of FIG. 5, the upper blood pressure value “132” and the lower blood pressure value “71” are associated with the provisional user ID “PID-1” as the measurement result of the biological information of the measurement date “2007/8/2”. ", The pulse rate" 74 "is described. In association with the provisional user ID “PID-2”, the upper blood pressure value “133”, the lower blood pressure value “73”, and the pulse rate “82” are obtained as measurement results of the measurement date “2007/8/20”. Is described.

(B) Operation | movement of embodiment Next, operation | movement of embodiment is demonstrated along the content of each table illustrated in FIGS.
FIG. 6 is a flowchart showing the flow of processing executed by the CPU 11 of the blood pressure measurement management device 1. In FIG. 6, first, the person to be measured brings his / her fingertip into contact with the fingerprint reading device 18 in order to log in to the blood pressure measurement management apparatus 1. The CPU 11 causes the fingerprint reading device 18 to read the fingerprint of the fingertip, and obtains fingerprint data representing the reading result as authentication information (step S1). Then, the CPU 11 performs authentication by comparing the fingerprint data stored in the storage unit 16 with the fingerprint data acquired from the fingerprint reading device 18 (step S2), and in the fingerprint data stored in the storage unit 16 Whether or not the measurement subject has been successfully authenticated is determined based on whether or not there is a match with the fingerprint data acquired from the fingerprint reading device 18 (step S3).

(B-1) When Authentication Fails Here, the operation of the blood pressure measurement management device 1 when user authentication fails in step S3 will be described.
When the fingerprint data that matches the acquired fingerprint data is not stored in the storage unit 16, the CPU 11 determines that the authentication has failed (step S <b>3; NO), and who is the subject to be authenticated is determined. Whether it is unknown or not, the process proceeds to step S4. And CPU11 displays the message which guides the measuring method of biometric information on the display part 15, etc., and makes the measurement part 17 measure biometric information of a to-be-measured person (step S4). That is, according to this guidance, when the measurement subject wraps the cuff 171 around the upper arm and instructs the measurement of the biological information by operating the operation unit 14, the CPU 11 measures the biological information to the measurement unit 17 accordingly. When the measurement is completed, the measurement result is acquired.

Subsequently, the CPU 11 responds to the person to be measured based on the degree of similarity between the obtained measurement result of the biometric information and the measurement result of the past biometric information written in the registered user biometric information management table 162. The process for specifying the registered user to be started is started.
First, the CPU 11 calculates, for each registered user, the similarity between the measurement result of the current measurement performed in step S4 and the past measurement result written in the registered user biometric information management table 162 (step S5). . Specifically, the CPU 11 calculates the average value of the measurement results for a predetermined period (eg, three months) retroactive from the current date and time as “upper blood pressure value”, “lower blood pressure value”, and “pulse rate”. For each measurement item. For example, if the current date and time is “2007/8/25”, the registered user A calculates the average value of the measurement results from “2007/07/18” to “2007/08/23” in FIG. Become. The CPU 11 calculates the similarity by dividing the average value of each measurement item by the value of the current measurement result. Then, the CPU 11 calculates an average value for all the measurement items (“upper blood pressure value”, “lower blood pressure value”, and “pulse rate”) of the calculated similarity, and expresses this as a percentage. The similarity to the registered user. The higher the similarity between the two, the closer the calculated value approaches “100%”.

  Then, the CPU 11 specifies a registered user having the highest calculated similarity and exceeding a predetermined threshold (for example, 90%) (step S6). For example, if the similarity to the registered user A is 95%, the similarity to the registered user B is 73%, and the similarity to the registered user C is 91%, the CPU 11 exceeds the threshold and has the highest similarity. It is specified that the “registered user A” associated with the measurement result is highly likely to be the same person as the measurement subject to be measured this time. Since the biometric information has different characteristics depending on the person and rarely changes rapidly in a short period of time, the CPU 11 uses the biometric information as the characteristic amount of the person to be measured, thereby being the same person as the person to be measured. It is possible to identify registered users with high possibility.

  Here, if the registered user can be identified (step S6; YES), the CPU 11 asks the measured person whether the registered user is the same person as the measured person (step S7). Specifically, the CPU 11 displays the display screen M1 as shown in FIG. In step S6, since the CPU 11 has specified the registered user A, as shown in FIG. 7, the display screen M1 displays a message of a question “Is your registered user ID“ UID-A ”?”. At the same time, “Yes” and “No” soft buttons for answering this question are displayed. That is, the CPU 11 asks the person to be measured whether or not the measurement result of the biological information may be stored in association with the notified registered user ID “UID-A” (first questioning means). . At this time, if the registered user ID is a simple character string such as “UID-A” or the like, it is difficult for the measured person to determine whether or not it is his registered user ID. For example, “Dad” or “○ If a nickname such as “Chan” is used as the registered user ID, the determination is easy. The CPU 11 displays the display screen M1, and when either “Yes” or “No” is selected by operating the operation unit 14 by the measurement subject, the specified registration is determined according to the operation content. It can be determined whether or not the user ID is correct.

  Here, when the measured person selects the soft button “Yes”, the CPU 11 that has received the control signal indicating the operation content specifies that the registered user having the highest similarity is the same person as the measured person. (Step S8; YES). In this case, since the measurement result is instructed to be stored in association with the registered user ID by the response operation of the measured person, the CPU 11 performs registration in the registered user biometric information management table 162. The measurement date and the measurement result of the biological information are written in association with the user ID (step S9). As a result, the contents of the registered user biometric information management table 162 are as shown in FIG. As shown in FIG. 8, if the current measurement result is the upper blood pressure value “132”, the lower blood pressure value “72”, and the pulse rate “76”, this processing results in the field F1 shown in FIG. Thus, the measurement result is newly written in association with the current date and time “2007/8/25”.

  On the other hand, when the measured person selects the “No” soft button, the CPU 11 that has received the control signal indicating the operation content determines that the specified registered user is not the same person as the measured person (step S8; NO). ), A “provisional user ID” different from the registered user ID is generated (step S10). The provisional user ID generated at this time is a provisional user ID other than the provisional user IDs (PID-1 and PID-2) already written in the provisional user biometric information management table 163, for example, “PID-3”. . Then, the CPU 11 associates the generated provisional user ID with the measurement result and writes it in the provisional user biometric information management table 163 (step S11). As a result, as shown in FIG. 9, the measurement result of the biological information is written in the field F2 of the temporary user biometric information management table 163 in association with the temporary user ID “PID-3”. At this time, the CPU 11 notifies the measured user (provisional user) of the provisional user ID, for example, by displaying the written provisional user ID “PID-3” on the display unit 15. The provisional user remembers it or leaves it in a memo so that it is not forgotten. The provisional user ID notified at this time is used in the process of “when authentication is successful” described later. In order to make it difficult for the temporary user to forget this temporary user ID, it is desirable to use a measure such as using the measurement date and time as the temporary user ID or using the fruit name as the temporary user ID.

By the way, in step S6, the determination result may be “NO”, and there may be no registered user ID whose similarity exceeds a threshold value. In this case, the person to be measured is a new user, or the person to be measured is a registered user, but the person to be measured is specified because the biological information has changed more than originally expected. It was impossible. In this case, the CPU 11 proceeds to step S10 and writes the temporary user ID and the measurement result in the temporary user biometric information management table 163.
The above is the processing when authentication fails. As described above, even if the authentication fails, if a registered user who is the same person as the person to be measured can be specified, the measurement result is written in the registered user biometric information management table 162. The measurement result is written in the user biometric information management table 163 in association with the temporary user ID.

(B-2) When Authentication is Successful Next, the operation of the blood pressure measurement management device 1 when authentication is successful in step S3 will be described.
The determination result in step S3 is “YES”, and the CPU 11 stores the fingerprint data that matches the acquired fingerprint data in the storage unit 16, and determines that the authentication is successful, based on the authentication information management table 161, A registered user who is the same person as the subject to be authenticated is specified (step S12). Here, it is assumed that the CPU 11 specifies that the registered user ID “UID-A” is assigned to the measurement subject.

  Subsequently, the CPU 11 performs a process for determining whether or not the provisional user to which the provisional user ID is assigned is the same person as the registered user identified here before measuring the biometric information. As described above, the CPU 11 treats the measurement subject whose provisional user ID is written in the provisional user biometric information management table 163 as a new user. However, although the registered user cannot be specified based on the similarity of the biometric information, the registered user and the provisional user may be the same measured person. This is because, for example, if the measurement result in step S4 is measured immediately after the subject performs intense exercise or is measured when the health condition is poor, In this case, the CPU 11 cannot write the registered user from the similarity of the biometric information and writes the measurement result in the provisional user biometric information management table 163.

  Therefore, first, the CPU 11 determines whether or not at least one provisional user ID is written in the provisional user biometric information management table 163 (step S13). Here, if the CPU 11 determines that no temporary user ID is written in the temporary user biometric information management table 163 (step S13; NO), there is no temporary user to which the temporary user ID is assigned. There is no need to perform the process of specifying the person to be measured corresponding to the provisional user ID. Therefore, the CPU 11 causes the measurement unit 17 to measure the biological information of the measurement subject (step S14). Then, when the measurement result of the biological information is acquired from the measurement unit 17, the CPU 11 associates the specified registered user ID with the measurement result and writes it in the field of the registered user biological information management table 162 (step S15). The measurement result here is associated with the registered user ID “UID-A”, and each measurement result is an upper blood pressure value “132”, a lower blood pressure value “72”, and a pulse rate “76”. The contents of the registered user biometric information management table 162 after this processing is performed are the same as those in FIG.

  On the other hand, when the CPU 11 determines that at least one provisional user ID is written in the provisional user biometric information management table 163 (step S13; YES), the provisional user ID assigned to the subject in the past is assigned to the subject. The subject is inquired as to whether or not there is (step S16). Specifically, the CPU 11 displays the display screen M2 as shown in FIG. As shown in FIG. 10, this display screen M2 includes a message “Are you measuring with a provisional user ID in the past?” And “Yes” and “No” for responding to this question. Is displayed.

  Here, when the measured person determines that there is no provisional user ID assigned to himself / herself and selects the “No” soft button (step S16; NO), the CPU 11 that has received the control signal representing the operation content is the CPU 11 that receives the control signal. In order to perform only the measurement of the biological information, the process proceeds to step S14.

  On the other hand, when the “Yes” soft button is selected (step S16; YES), the CPU 11 asks the person to be measured about the provisional user ID (second questioning means) (step S17). Here, the CPU 11 causes the display unit 15 to display a display screen M3 requesting input of a provisional user ID. As shown in FIG. 11, the display screen M <b> 3 is selected when the input form M <b> 31 and the input of the temporary user ID are completed together with a message “Please input your temporary user ID”. A “complete” soft button and a “stop” soft button for canceling the provisional user ID input are displayed. Here, the person to be measured inputs the temporary user ID that he / she remembers to the input form M31, and selects the “complete” soft button. In response to this, the CPU 11 determines whether or not the input temporary user ID matches the temporary user ID written in the temporary user biometric information management table 163 (step S18). The measured user does not input the provisional user ID itself, but the CPU 11 displays the provisional user IDs written in the provisional user biometric information management table 163 on the display unit 15 in a list format. A method in which the measurement subject selects his / her temporary user ID may be used.

  If the CPU 11 determines that there is a matching provisional user ID (step S18; YES), the measurement result associated with the provisional user ID in the provisional user biometric information management table 163 is specified by authentication. Write in the registered user biometric information management table 162 in association with the user ID “UID-A” (step S19). As a result, the registered user biometric information management table 162 is as shown in FIG. FIG. 12 shows a field corresponding to the registered user ID “UID-A” when the provisional user ID “PID-1” is input by the measurement subject. As shown in the field F3 in the figure, the measurement result of the biometric information written in association with the temporary user ID “PID-1” in the temporary user biometric information management table 163 in FIG. It is written in association with the registered user ID “UID-A” in the table 162.

  When this measurement result is written, the provisional user assigned the provisional user ID “PID-1” is identified as the same person as the registered user “registration user A”. “PID-1” and the corresponding measurement result are deleted from the provisional user biometric information management table 163 (step S20).

  By the way, if the determination result of step S18 is “NO” and the CPU 11 determines that there is no entry in the temporary user biometric information management table 163 that matches the input temporary user ID, the process proceeds to step S14. At this time, since there is a possibility that the measurement subject may make an input error, the CPU 11 displays a message “Please input again” until the provisional user ID authentication fails a predetermined number of times (for example, 5 times). 15 may be returned to step S17. Even when the “Cancel” soft button is selected on the display screen M3, the CPU 11 cannot identify the user corresponding to the temporary user ID in step S18, and proceeds to step S14.

According to the embodiment described above, if the authentication fails, the blood pressure measurement management device 1 is the person to be measured based on the similarity between the measurement result of the biological information in the current measurement and the past measurement result. Determine if it exists. If it can be determined that the person to be measured is a registered user, the blood pressure measurement management device 1 writes the measurement result in the field corresponding to the registered user ID in the registered user biometric information management table 162. On the other hand, if the person to be measured cannot be specified as a registered user, the measurement result is written in the temporary user biometric information management table 163 in association with the newly generated temporary user ID. If the authentication is successful, the measurement subject is asked whether the temporary user ID has been measured in the past. If the temporary user ID is input by the measurement subject, the measurement result associated with the temporary user ID. Is rewritten from the provisional user biometric information management table 163 to the registered user biometric information management table 162.
Thus, since the person to be measured is identified from the measurement result of the biological information, the apparatus configuration is simple, and the measurement person is required to perform complicated work for authentication. Therefore, the measurement result of biological information can be managed correctly.

(C) Modifications The above embodiment may be modified as follows. Specifically, the following modifications are mentioned, for example. These modifications can be appropriately combined with each other.
(C-1) Modification 1
In the above-described embodiment, the biological information measurement management apparatus that measures the blood pressure value and the pulse rate has been described as an example, but an apparatus that measures other biological information may be used. For example, when a body fat meter is used as the biological information measurement management device, the body weight and body fat percentage of the measurement subject are measured as biological information, and user management is performed based on the measurement results. In this case, since the person to be measured stands at a predetermined position provided in the measurement unit, the fingerprint of the toe may be used for authentication. In addition to these devices, any device that measures biological information whose characteristics appear in the measurement results by the person being measured, such as a device that measures height, vital capacity, or a device that measures muscle strength such as grip strength or back muscle strength. It can be used as a biological information management device.
Moreover, although it was an example of the biological information measurement management apparatus provided with a measurement part in embodiment, this invention can be comprised even if it is a biological information management apparatus which made this measurement part an external structure. In this case, the CPU of the biological information management device acquires the measurement result as the measurement result of the measured person from the measurement unit that measures the biological information of the measured person and outputs the measurement result, and performs the above-described processing. .

(C-2) Modification 2
In the calculation of the similarity in step S5 of the above-described embodiment, the current measurement result is divided by the average value of the past measurement results for each measurement item, and the average value of all the measurement items is calculated. This is the similarity of the biometric information to the registered user. However, this similarity may be calculated using other methods.
For example, even if the registered user and the person to be measured are not the same person, the degree of similarity of a certain measurement item will increase by chance, and even if the degree of similarity of other measurement items is low, The degree of similarity increases, and in this case, there is a possibility that the registered user is erroneously specified. Therefore, a threshold is provided for each measurement item, and if there is at least one measurement item whose similarity is lower than this threshold, the CPU 11 may determine that this registered user is a person different from the person to be measured. Good.

  In addition, when a threshold is provided for each measurement item, there are a measurement result that is likely to change depending on a health condition and a change that is difficult to change depending on the measurement contents. For example, the “heart rate” is normally “60-100” for an adult male, but may exceed “150” after intense exercise, etc. Is big. On the other hand, “body weight”, “body fat” and the like rarely vary greatly in a short period of time. Therefore, for a measurement item with a large degree of time-series change such as “heart rate”, the threshold value used for determining the similarity is lowered, and “weight” and “body fat” For a measurement item with a small degree of time series change, the threshold value may be increased. The threshold corresponding to such a measurement item may be set in advance at the design stage of the blood pressure measurement management device 1, or the blood pressure measurement management device 1 itself refers to a past measurement result of a registered user, An appropriate threshold value may be set based on the magnitude of the fluctuation amount of the measurement result with respect to the passage of time. According to such a configuration, it is possible to more accurately identify the person to be measured regardless of the characteristics of the biological information to be measured.

  In the embodiment, the average value of the measurement results over the past three months is calculated, but the calculation target period of the average value may be a longer period or a shorter period. However, if the old measurement results are used to calculate the similarity, the biometric information may change significantly due to the growth of the person being measured, changes in the health condition, etc. It is preferable to lower the threshold value for determination. In this way, even if there is a change in the measurement subject's biological information, it is possible to accurately identify who the measurement subject is. On the contrary, when shortening this period, if the threshold value is increased, it is possible to accurately identify who the measurement subject is.

(C-3) Modification 3
In steps S6 and S7 of the above-described embodiment, the registered user corresponding to the measurement result having the highest similarity of the calculated measurement result and the similarity exceeding a predetermined threshold (90%) is The possibility of being the same person is high, and the subject was asked whether this was correct. As described above, since the biometric information is a feature amount for specifying a person, if the similarity is as close as possible to 100%, the registered user and the person to be measured are almost certainly the same person. I can say that. Thus, for example, if the degree of similarity is equal to or higher than a first threshold (for example, 95%), the CPU 11 skips step S7 and proceeds to S8, and the registered user and the person being measured do not ask the person being measured. If it is specified that they are the same person, and the similarity is equal to or higher than a second threshold value (for example, 90%) and lower than the second threshold value (95%), whether or not the user is a registered user in step S7 It may be configured to ask whether or not.

(C-4) Modification 4
In the above-described embodiment, when authentication (steps S1 to S3) fails, the processing steps of steps S4 to S11 are executed, and the process for specifying the registered user from the similarity of the biometric information is performed. The authentication may be omitted. In this case, since the blood pressure measurement management device 1 starts the process from step S4 without performing authentication, the blood pressure measurement management device 1 identifies the person to be measured from only the measurement result of the biological information. In this case, when the person to be measured instructs via the operation unit 14 to perform the measurement, the blood pressure measurement management device 1 immediately measures the biological information, and the similarity between the measurement result at that time and the past measurement result is obtained. Based on this, the person to be measured is specified. In this way, it is not necessary for the measurement subject to perform complicated work for authentication, and smooth measurement is possible.

(C-5) Modification 5
In the above-described embodiment, authentication by fingerprint is performed. Instead, so-called biometric authentication using biometric information such as retina authentication and vocal cord authentication can be performed. If such biometric authentication is used, highly accurate authentication can be easily performed without causing the user to perform complicated operations such as inputting a password.
Further, it is preferable to use an authentication unit corresponding to a measurement item of biological information. For example, in the blood pressure measurement management device 1, the person to be measured performs measurement by winding the cuff 171 around the arm, so that the blood pressure measurement management device 1 provides authentication information necessary for authentication via the cuff 171 at the start of measurement. If it can be acquired, it is possible to reduce troublesome work that the measurement subject has to perform for authentication. For this purpose, the blood pressure measurement management device may perform authentication using, for example, a pulse wave.

(C-6) Modification 6
The programs executed by the CPU 11 described above are recorded on a magnetic tape, a magnetic disk, a floppy (registered trademark) disk, an optical recording medium, a magneto-optical recording medium, a CD (Compact Disk), a DVD (Digital Versatile Disk), a RAM, and the like. It can be provided as recorded on the medium.
