[0009] Hereinafter, embodiments of an information processing device, an information processing method, and a recording medium will be described with reference to the drawings. [1: First Embodiment]

[0010] A first embodiment of an information processing device, an information processing method, and a recording medium will be described below. Hereinafter, the first embodiment of the information processing device, the information processing method, and the recording medium will be described using an information processing device 1 to which the first embodiment of the information processing device, the information processing method, and the recording medium is applied. [1-1: Configuration of Information Processing Device 1]

[0011] 1 is a block diagram showing the configuration of an information processing device 1 according to the first embodiment. As shown in FIG. 1, the information processing device 1 includes an authentication unit 11, a storage control unit 12, and an output unit 13.

[0012] The authentication unit 11 authenticates a target person using the target person's biometric information. The storage control unit 12 stores target information including biometric information and authentication information related to authentication using the biometric information in association with the target person. The output unit 13 outputs physical information related to the target person's body that is estimated using two or more pieces of target information about the target person stored in the storage control unit 12. [1-2: Technical Effects of the Information Processing Device 1]

[0013] The information processing device 1 according to the first embodiment can estimate the body of a target person from two or more pieces of authentication information and biometric information used for the authentication, and output target information about the body of the target person. [2: Second Embodiment]

[0014] Next, a second embodiment of the information processing device, the information processing method, and the recording medium will be described. Hereinafter, the second embodiment of the information processing device, the information processing method, and the recording medium will be described using an information processing device 2 to which the second embodiment of the information processing device, the information processing method, and the recording medium is applied. [2-1: Configuration of the information processing device 2]

[0015] 2 is a block diagram showing the configuration of an information processing device 2 in the second embodiment. As shown in FIG. 2, the information processing device 2 includes a calculation device 21 and a storage device 22. The information processing device 2 may further include a communication device 23, an input device 24, and an output device 25. However, the information processing device 2 does not necessarily have to include at least one of the communication device 23, the input device 24, and the output device 25. The calculation device 21, the storage device 22, the communication device 23, the input device 24, and the output device 25 may be connected via a data bus 26.

[0016] The arithmetic device 21 includes, for example, at least one of a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), and an FPGA (Field Programmable Gate Array). The arithmetic device 21 reads a computer program. For example, the arithmetic device 21 may read a computer program stored in the storage device 22. For example, the arithmetic device 21 may read a computer program stored in a computer-readable, non-transitory recording medium using a recording medium reading device (e.g., an input device 24 described later) not shown in the drawings that is included in the information processing device 2. The arithmetic device 21 may acquire (i.e., download or read) the computer program from a device (not shown) located outside the information processing device 2 via the communication device 23 (or another communication device). The arithmetic device 21 executes the read computer program. As a result, logical functional blocks for executing the operations to be performed by the information processing device 2 are realized within the arithmetic device 21. In other words, the arithmetic device 21 can function as a controller for realizing logical functional blocks for executing the operations (in other words, processing) to be performed by the information processing device 2.

[0017] FIG. 2 shows an example of logical functional blocks implemented within the computing device 21 to execute information processing operations. As shown in FIG. 2 , the computing device 21 includes an authentication unit 211, which is a specific example of "authentication means" described in the appendix below; a memory control unit 212, which is a specific example of "storage means" described in the appendix below; an output unit 213, which is a specific example of "output means" described in the appendix below; and a biometric information acquisition unit 214. The authentication unit 211 includes a score calculation unit 2111 and an authentication determination unit 2112. The output unit 213 includes an estimation unit 2131 and an output determination unit 2132. However, at least one of the memory control unit 212 and the biometric information acquisition unit 214 does not necessarily have to be implemented within the computing device 21. The authentication unit 211 does not necessarily have to include the score calculation unit 2111. Furthermore, the output unit 213 may not necessarily include at least one of the estimation unit 2131 and the output determination unit 2132. The output unit 213 may include the estimation unit 2131 but not the output determination unit 2132. In this case, the function of the output determination unit 2132, which will be described later, may be realized, for example, inside the information processing device 2 separately from the output unit 213. Alternatively, the function of the output determination unit 2132 may be realized in a cloud external to the information processing device 2. Furthermore, the output unit 213 may not include the estimation unit 2131 but may include the output determination unit 2132. In this case, the function of the estimation unit 2131, which will be described later, may be realized, for example, inside the information processing device 2 separately from the output unit 213. Alternatively, the function of the estimation unit 2131 may be realized in a cloud external to the information processing device 2. Furthermore, the output unit 213 may not include the estimation unit 2131 or the output determination unit 2132. In this case, at least one of the functions of the estimation unit 2131 and the output determination unit 2132 described below may be realized, for example, inside the information processing device 2 separately from the output unit 213. Alternatively, at least one of the functions of the estimation unit 2131 and the output determination unit 2132 described below may be realized in a cloud outside the information processing device 2. When the output unit 213 does not have the estimation unit 2131 or the output determination unit 2132, the output unit 213 may be a mechanism that acquires estimated physical information to be output and outputs the physical information.The operations of the authentication unit 211, the storage control unit 212, the output unit 213, and the biometric information acquisition unit 214 will be described in detail later with reference to FIG.

[0018] The storage device 22 can store desired data. For example, the storage device 22 may temporarily store a computer program executed by the arithmetic device 21. The storage device 22 may temporarily store data temporarily used by the arithmetic device 21 when the arithmetic device 21 is executing a computer program. The storage device 22 may store data to be stored long-term by the information processing device 2. The storage device 22 may include at least one of a RAM (Random Access Memory), a ROM (Read Only Memory), a hard disk device, a magneto-optical disk device, an SSD (Solid State Drive), and a disk array device. In other words, the storage device 22 may include a non-transitory recording medium. The storage device 22 may include a target information storage unit 221, a registered biometric information storage unit 222, and a reference storage unit 223, which are specific examples of the "storage device" described in the appendix below. The storage control unit 212, which is a specific example of a "storage means" described in the appendix below, may store information in the target information storage unit 221, which is a specific example of a "storage device" described in the appendix below. However, any of the target information storage unit 221, the registered biometric information storage unit 222, and the reference storage unit 223 may not be implemented within the storage unit 22. If any of the target information storage unit 221, the registered biometric information storage unit 222, and the reference storage unit 223 is not implemented within the storage unit 22, the storage unit may be implemented in a device external to the information processing device 2. In this case, the calculation device 21 may transmit and receive information to and from a storage unit implemented in an external device, for example, via the communication device 23 described below. Details of the target information storage unit 221, the registered biometric information storage unit 222, and the reference storage unit 223 will be described later with reference to FIG. 3 and Table 1.

[0019] The communication device 23 is capable of communicating with devices external to the information processing device 2 via a communication network (not shown). The communication device 23 may be a communication interface based on standards such as Ethernet (registered trademark), Wi-Fi (registered trademark), Bluetooth (registered trademark), or USB (Universal Serial Bus).

[0020] The input device 24 is a device that accepts information input to the information processing device 2 from outside the information processing device 2. For example, the input device 24 may include an operation device (e.g., at least one of a keyboard, a mouse, and a touch panel) that can be operated by an operator of the information processing device 2. For example, the input device 24 may include a reading device that can read information recorded as data on a recording medium that can be externally attached to the information processing device 2.

[0021] The output device 25 is a device that outputs information to the outside of the information processing device 2. For example, the output device 25 may output information as an image. That is, the output device 25 may include a display device (a so-called display) that can display an image showing the information to be output. For example, the output device 25 may output information as sound. That is, the output device 25 may include an audio device (a so-called speaker) that can output sound. For example, the output device 25 may output information on paper. That is, the output device 25 may include a printing device (a so-called printer) that can print desired information on paper. [2-2: Application Scenarios of the Information Processing Device 2]

[0022] The information processing device 2 in this embodiment may be applied to a situation where biometric authentication using biometric information of a target is performed. The information processing device 2 may be applied to a situation where biometric authentication using an image, such as iris authentication or face authentication, is performed. The information processing device 2 may also be applied to a situation where biometric authentication, such as voice authentication using a microphone, ear acoustic authentication using earphones, fingerprint authentication, or vein authentication, is performed. The information processing device 2 may also be applied to a situation where biometric authentication of a target person is performed on a daily basis, such as entering and exiting a restricted area where authenticated target persons can enter, such as an office or an apartment building. [2-3: Information Processing Operation Performed by the Information Processing Device 2]

[0023] The information processing operation performed by the information processing device 2 will be described with reference to Fig. 3. Fig. 3 is a flowchart showing the flow of the information processing operation performed by the information processing device 2. The information processing device 2 may start the information processing operation in response to an authentication execution instruction operation by the target person.

[0024] As shown in FIG. 3 , the biometric information acquisition unit 214 acquires biometric information (step S20). For example, when the information processing device 2 performs iris authentication, the biometric information acquisition unit 214 may acquire an eye image showing an eye including an iris. In this case, the biometric information acquisition unit 214 may acquire an eye image captured by an infrared camera. Alternatively, the biometric information acquisition unit 214 may acquire an eye image captured by a visible light camera. Furthermore, when the information processing device 2 performs face authentication, the biometric information acquisition unit 214 may acquire a face image showing a face. In this case, the biometric information acquisition unit 214 may acquire a face image captured by a visible light camera. Alternatively, the biometric information acquisition unit 214 may acquire a face image captured by an infrared camera. Furthermore, when the information processing device 2 performs multimodal authentication including iris authentication and face authentication, the biometric information acquisition unit 214 may acquire an eye image and a face image.

[0025] The score calculation unit 2111 compares the biometric information of the target person with the biometric information registered in the registered biometric information storage unit 222 (step S21). The score calculation unit 2111 may compare the feature amount extracted from the biometric information of the target person with the feature amount extracted from the biometric information registered in the registered biometric information storage unit 222. The score calculation unit 2111 calculates an authentication score.

[0026] The authentication assessment unit 2112 determines whether or not the authentication is successful using the matching result by the score calculation unit 2111 (step S22). The authentication assessment unit 2112 may determine whether or not the authentication is successful depending on whether or not the authentication score as the matching result exceeds a predetermined threshold. That is, the authentication unit 211 authenticates the target person using the target person's biometric information. The authentication assessment unit 2112 may determine whether or not the target person is allowed to enter an office, an apartment building, etc., based on the authentication result.

[0027] If the authentication fails (step S22: No), the information processing operation ends. In this case, the target person may issue an instruction to the information processing device 2 to perform authentication again.

[0028] If the authentication is successful (step S22: Yes), the storage control unit 212 stores target information including biometric information and authentication information related to authentication using the biometric information in the target information storage unit 221 in association with the target person (step S23). The storage control unit 212 stores the target information in the target information storage unit 221 in association with the identified target person. The storage control unit 212 may store at least one of an eye image and a face image as biometric information in the target information storage unit 221. The storage control unit 212 may store authentication information including information indicating the date and time when authentication was performed and an authentication score of the performed authentication in the target information storage unit 221.

[0029] The estimation unit 2131 estimates physical information related to the target person's body using two or more pieces of target information related to authentications performed on different dates and times for the target person stored in the target information storage unit 221 (step S24). The estimation unit 2131 may estimate the target person's physical information using at least one piece of past target information and current target information. The estimation unit 2131 may estimate the target person's physical information by comparing at least one piece of past target information with the current target information. The estimation unit 2131 may estimate the target person's physical information based on time-series changes in the biometric information stored in the target information storage unit 221. The estimation unit 2131 may estimate the target person's physical information based on time-series changes in the authentication score stored in the target information storage unit 221.

[0030] The physical information may include health information indicating the health condition of the target person. The health information may include information indicating signs of illness. The estimation unit 2131 may detect signs of illness. When the estimation unit 2131 detects signs of illness, it may recommend that the target person visit a medical institution. The health information may include information indicating a recommendation to visit a medical institution.

[0031] The estimation unit 2131 may estimate a physical condition, including physical abnormalities, based on changes in at least one of the biometric information acquired at different dates and times and the authentication score. Since authentication is performed daily, changes in the authentication score are often related to physical changes. The estimation unit 2131 may detect daily changes in the target person's body by using information that can be acquired during authentication. The estimation unit 2131 may monitor the authentication score over time and suspect a sign of illness if the authentication score drops. Furthermore, the estimation unit 2131 may acquire information indicating a fitness state, such as the number of steps, and use it to estimate the physical information. The estimation unit 2131 may acquire information indicating a fitness state, such as the number of steps, from a device carried or worn by the target person, such as a smartphone or a smartwatch.

[0032] When the estimation unit 2131 detects a change in the body, it may determine whether the change is sudden or gradual. For example, when a sudden change in the body is detected, the estimation unit 2131 may estimate that the change is a pathological change. For example, if the change in the body occurs in one day, the estimation unit 2131 may estimate that the change is a pathological change. Furthermore, when a gradual change in the body is detected, the estimation unit 2131 may estimate that the change is not a pathological change. For example, if a change occurs over a long period of time, it may be estimated that the change is a natural change due to aging. Furthermore, if an unhealthy lifestyle on one day results in an unusual condition only the next day, the estimation unit 2131 may not estimate that the change is a pathological change.

[0033] The estimation unit 2131 may have a plurality of methods for estimating the physical state based on information included in the image. The method by which the estimation unit 2131 estimates the physical state from time-series information of the image and the authentication score will be described later.

[0034] The estimation unit 2131 may make an estimation regarding a predetermined item from the information stored in the target information storage unit 221. The item may be an object to be estimated by the estimation unit 2131. The item may be an object to be detected in which a predetermined state is detected by the estimation unit 2131. The item may be an object to be detected for abnormality. The items may be either an item related to signs of illness or an item not related to signs of illness. Whether or not an item is a sign of illness may be determined based on a level described below. The items may be arbitrarily defined. Parts of the body may be defined as items. For example, the eyes, the mouth, etc. may be defined as items. Furthermore, for example, body temperature, heart rate, etc. may be defined as items.

[0035] The estimation unit 2131 may estimate that an abnormality exists when a predetermined state is detected in the image. The predetermined state may be a difference between the left and right sides of a predetermined part, or a time-series change in the difference. For example, even if a difference between the left and right sides exists, if the difference has continued for a long period of time, the estimation unit 2131 may estimate that the difference is a personality trait of the target person.

[0036] The output determination unit 2132 determines whether to output the estimation result (step S25). The output determination unit 2132 may determine whether to notify the target person of the estimation result. The output determination unit 2132 may compare the estimation result based on at least one of the image and the authentication score by the estimation unit 2131 with a standard to determine whether to output the result. The output determination unit 2132 may make a determination based on the degree of difference between the estimation result and the standard. The estimation unit 2131 may calculate a value as the estimation result for a predetermined item. The standard may be a value or a range. The estimation by the estimation unit 2131 may also be rephrased as detection of the target to be determined by the output determination unit 2132.

[0037] The reference storage unit 223 stores information used by the output determination unit 2132 for determination. The output determination unit 2132 may determine the level of an item by referring to the reference storage unit 223. The output determination unit 2132 may determine whether to output an item by comparing it with the information stored in the reference storage unit 223. The reference storage unit 223 may store a level range for each item, as shown in Table 1 below. [Table 1: Reference Storage Unit 223]

[0038]

[0039] The reference storage unit 223 may store a level range for each item, divided into five levels, for example, "1," "2," "3," "4," and "5." The level range may be a range of difference between the estimated value and the reference value. "1" may indicate a level where there is a mild abnormality but no particular problem and no particular attention is required. "2" may indicate a level where there is a mild abnormality but no particular problem. "2" may indicate a level where, unlike "1," a notification is issued to a target person who requests notification even if there is a mild abnormality. "1" and "2" may be understood as levels where there is no need to worry. "3" may indicate a level where there is a high possibility that some kind of disease is progressing. "3" may be understood as a level where caution is required. "3" may be a level where lifestyle improvement is recommended. "3" may be a level where a visit to a medical institution is recommended depending on the item. "4" may be a level where a visit to a medical institution is recommended. "5" may be a level where immediate visit to a medical institution is required.

[0040] The output determination unit 2132 may determine the level range of the difference between the value as the estimation result and the reference value. In the example shown in Table 1 above, the reference storage unit 223 stores information indicating that the level 1 range of item A is "1AL" to "1AH," the level 2 range of item A is "2AL" to "2AH," the level 3 range of item A is "3AL" to "3AH," the level 4 range of item A is "4AL" to "4AH," and the level 5 range of item A is "5AL" to "5AH." Furthermore, information indicating that the level 1 range of item B is "1BL" to "1BH," and the level 2 range of item B is "2BL" to "2BH." In this case, the output determination unit 2132 may determine that item A is level 1 if the difference between the value as the estimation result for item A and the reference value is within the range of "1AL" to "1AH." Furthermore, the output determination unit 2132 may determine that item B is at level 2 if the difference between the value as the estimation result for item B and the reference value is within the range of "2BL" to "2BH".

[0041] The standard for each item may be a value or range indicating normal for that item. The standard for each item may be determined from changes in past physical information of multiple individuals who have been determined to be abnormal for the same item by a medical institution. That is, a model of an individual who is likely to become ill in the future may be formed from information on multiple individuals who have been determined to be abnormal for the same item by a medical institution. Furthermore, a model of an individual who is unlikely to become ill in the future may be formed from information on multiple individuals who have not been determined to be abnormal for the same item by a medical institution. The standard for each item may be determined from these formed models.

[0042] The output determination unit 2132 may determine whether to output the signal depending on the level. That is, even if the estimation unit 2131 detects a difference from the reference, if the output determination unit 2132 determines that the difference is not at a level sufficient to warrant output, the signal may not be output.

[0043] If it is determined that the information should be output (step S25: Yes), the output unit 213 outputs physical information about the target person's body (step S26). The output unit 213 may notify the target person by transmitting the physical information to a terminal device that the target person can use. The terminal device may be a personal computer, a smartphone, or other device that can be connected to the information processing device 2 via the Internet. The output unit 213 may output a text explaining the level of the corresponding item, as well as related images, such as images that serve as the basis for the estimation.

[0044] If the level for each item is "3" or higher, the output unit 213 may notify the target person of an abnormality in their health. If a symptom of illness is detected, the output unit 213 may also output measures to address the symptom of illness. The measures may include visiting a medical institution. Furthermore, if the level for each item is "2," the output unit 213 may notify the target person of their health condition. [Variation: Determination According to Target Person]

[0045] In a modified example, the notification content registration unit 224 may be implemented in the storage device 22. The notification content registration unit 224 may store information indicating at what level the target person wishes to be notified of physical information. The output determination unit 2132 may refer to the notification content registration unit 224 and make a determination according to the target person. The notification content registration unit 224 may store information indicating whether or not notification of physical information is required for each target at the corresponding level for each item, as exemplified in Table 2 below. [Table 2: Notification content registration unit 224]

[0046]

[0047] The notification content registration unit 224 may store, for each target, whether or not notification of physical information is required, for each item, at a level categorized into five levels, for example, "1," "2," "3," "4," and "5." In the example shown in Table 2 above, the notification content registration unit 224 stores information indicating that, with respect to target person P1, when the level of item A is 1 or 2, notification is not required, and when the level of item A is 3 to 5, notification is required. The notification content registration unit 224 also stores information indicating that, with respect to target person P1, when the level of item B is 1, notification is not required, and when the level of item B is 2, notification is required. The notification content registration unit 224 also stores information indicating that, with respect to target person P2, when the level of item A is 1, notification is not required, and when the level of item A is 2, notification is required. [2-4: Technical Effects of Information Processing Device 2]

[0048] The information processing device 2 in the second embodiment uses the image of the target person captured during authentication for a purpose other than authentication. The information processing device 2 can utilize the image captured during authentication and the authentication score obtained during authentication for healthcare. The information processing device 2 can grasp the daily condition, and therefore can grasp the condition more accurately than periodic condition grasp, for example, monthly.

[0049] The information processing device 2 notifies the user when an abnormality occurs, allowing the user to notice the abnormality early and take action. By receiving notification of physical information, the target person can grasp the state of their physical condition and signs of illness that they may not be aware of themselves. Furthermore, this can also lead to the promotion of the target person's health. [3: Third embodiment]

[0050] Next, a third embodiment of the information processing device, the information processing method, and the recording medium will be described. Hereinafter, the third embodiment of the information processing device, the information processing method, and the recording medium will be described using an information processing device 3 to which the third embodiment of the information processing device, the information processing method, and the recording medium is applied. [3-1: Configuration of the information processing device 3]

[0051] As shown in FIG. 4 , the information processing device 3 in the third embodiment includes a calculation device 21 and a storage device 22, similar to the information processing device 2 in the second embodiment. Furthermore, the information processing device 3 in the third embodiment may include a communication device 23, an input device 24, and an output device 25, similar to the information processing device 2 in the second embodiment. However, the information processing device 3 does not need to include at least one of the communication device 23, the input device 24, and the output device 25. The information processing device 3 in the third embodiment differs from the information processing device 2 in the second embodiment in that the authentication unit 311 includes an iris matching unit 3113. The information processing device 3 performs iris authentication. Other features of the information processing device 3 may be the same as those of the information processing device 2 in the second embodiment. Therefore, the following will describe in detail the differences from the embodiments already described, and will omit descriptions of other overlapping features as appropriate. [3-2: Information Processing Operation Performed by Information Processing Device 3]

[0052] An information processing operation performed by the information processing device 3 will be described with reference to Fig. 3. The information processing device 3 may start the information processing operation in response to an authentication execution instruction operation by the target person.

[0053] The biometric information acquisition unit 314 acquires an eye image showing the eye including the iris (step S20). The biometric information acquisition unit 414 may acquire the eye image captured by an infrared camera. Alternatively, the biometric information acquisition unit 214 may acquire the eye image captured by a visible light camera. Furthermore, when the information processing device 3 performs multimodal authentication including iris authentication and face authentication, the biometric information acquisition unit 314 may acquire the eye image and the face image.

[0054] The iris matching unit 3113 performs iris authentication on the target person using an eye image including the iris of the target person. The iris matching unit 3113 matches the eye image of the target person with the eye images registered in the registered biometric information storage unit 222 (step S21). The iris matching unit 3113 may match feature amounts extracted from the eye image of the target person with feature amounts extracted from the eye images registered in the registered biometric information storage unit 222.

[0055] The authentication determination unit 3112 determines whether or not authentication is successful using the matching result by the iris matching unit 3113 (step S22). If authentication is successful (step S22: Yes), the storage control unit 212 stores, in the target information storage unit 321, target information including the eye image, date and time information indicating the date and time when iris authentication using the eye image was performed, and authentication information including the authentication score of the performed iris authentication, in association with the target person (step S23).

[0056] The estimation unit 3131 estimates physical information of the target person using two or more pieces of target information related to authentication performed on different dates and times for the target person stored in the target information storage unit 321 (step S24). The estimation unit 3131 estimates physical information related to the target person's body using two or more pieces of target information related to iris authentication performed on different dates and times for the target person stored in the target information storage unit 321. The estimation unit 3131 may estimate the health condition related to the eyes of the target person. The estimation unit 3131 may estimate the possibility of an eye-related disease. [Estimation based on eye images]

[0057] The estimation unit 3131 may estimate the health condition of the target person's eyes from the eye image of the target person. The estimation unit 3131 may estimate the health condition of the target person's eyes from a time-series change in the eye image.

[0058] The estimation unit 3131 may detect discoloration of the skin around the eyes from the eye image. The skin discoloration may be darkening of the skin. The estimation unit 2131 may detect the discoloration as skin discoloration around the eyes when the color of the skin around the eyes is different from the color of the skin in other areas by a predetermined amount or more. Discoloration of the skin below the eyes may be considered to be dark circles under the eyes, and the output unit 213 may notify the target person that they are not getting enough sleep.

[0059] The estimation unit 3131 may detect discoloration of the sclera from the eye image. Discoloration of the sclera may be detected when the sclera contains more blood than a predetermined amount. When fatigue accumulates, the whites of the eyes become bloodshot, so the estimation unit 3131 may estimate that the person is in poor physical condition when the bloodshot whites of the eyes are greater than a predetermined amount. The estimation unit 3131 may detect overfatigue. Furthermore, the estimation unit 3131 may detect that the sclera is yellower than a predetermined amount. In this case, the estimation unit 3131 may estimate that an internal organ is not functioning properly.

[0060] The estimation unit 3131 may detect a difference between the left and right eyes from the eye image. The difference between the left and right eyes may be a difference in the size of the eyes. The difference between the size of the eyes may be a difference in the degree to which the eyelids are open. The difference between the left and right eyes may be a difference in the size of the pupils. The difference between the left and right eyes may be a difference in the color of the eyes. The difference between the left and right eyes may be a difference in the size of the irises of the eyes.

[0061] The estimation unit 3131 may detect the state of the iris from the eye image. The state of the iris may include the color of the iris. The estimation unit 3131 may detect a change in the color of the iris from the eye image. [Estimation Based on Authentication Score]

[0062] The estimation unit 3131 may estimate the eye-related health condition of the target person from the time-series change in the authentication score of the iris authentication stored in the target information storage unit 321.

[0063] For example, when the estimation unit 3131 detects a gradual decrease in the authentication score, it may estimate that the target person may have an eye-related disease. When a target person has an eye-related disease, it is often impossible to acquire an eye image including an iris suitable for iris authentication, compared to when the target person is not ill. For example, a change that occurs when a target person has an eye-related disease may be when the eyelids droop. In this case, the iris area included in the eye image may become smaller. Another change that occurs when a target person has an eye-related disease may be when the lens becomes cloudy. In this case, the color of the iris may change. Therefore, when a target person has an eye-related disease, the authentication score often decreases, compared to when the target person is not ill.

[0064] Furthermore, the estimation unit 3131 may be able to estimate whether there is a possibility of illness or deterioration due to aging, depending on how the authentication score drops. For example, when the estimation unit 2131 detects a rapid drop in the authentication score, it may estimate that there is a possibility of illness. Eye-related illnesses may include eye diseases such as glaucoma and cataracts, and diseases of the cranial nerves related to the eyes.

[0065] The output determination unit 3132 determines whether to output the determination result to the target person (step S25). If it is determined that the result should be output (step S25: Yes), the output unit 313 outputs physical information about the target person's body (step S26). [3-3: Technical Effects of the Information Processing Device 3]

[0066] The information processing device 3 in the third embodiment can notify the target person of the eye-related health condition by using the information used in the iris authentication. [4: Fourth embodiment]

[0067] Next, a fourth embodiment of the information processing device, the information processing method, and the recording medium will be described. Hereinafter, the fourth embodiment of the information processing device, the information processing method, and the recording medium will be described using an information processing device 4 to which the fourth embodiment of the information processing device, the information processing method, and the recording medium is applied. [4-1: Configuration of the information processing device 4]

[0068] As shown in FIG. 5 , the information processing device 4 in the fourth embodiment includes a calculation device 21 and a storage device 22, similar to the information processing device 2 in the second embodiment and the information processing device 3 in the third embodiment. Furthermore, the information processing device 4 in the fourth embodiment may include a communication device 23, an input device 24, and an output device 25, similar to the information processing device 2 in the second embodiment and the information processing device 3 in the third embodiment. However, the information processing device 3 does not need to include at least one of the communication device 23, the input device 24, and the output device 25. The information processing device 4 in the fourth embodiment differs from the information processing device 2 in the second embodiment and the information processing device 3 in the third embodiment in that the authentication unit 411 includes a face matching unit 4114. The information processing device 4 performs face authentication. Other features of the information processing device 4 may be the same as other features of at least one of the information processing device 2 in the second embodiment and the information processing device 3 in the third embodiment. Therefore, hereinafter, differences from the already-described embodiments will be described in detail, and descriptions of other overlapping features will be omitted as appropriate. [4-2: Information Processing Operation Performed by Information Processing Device 4]

[0069] The information processing operation performed by the information processing device 4 will be described with reference to Fig. 3. The information processing device 4 may start the information processing operation in response to an authentication execution instruction operation by the target person.

[0070] The biometric information acquisition unit 414 acquires a facial image (step S20). The biometric information acquisition unit 414 may acquire a facial image captured by a visible light camera. Alternatively, the biometric information acquisition unit 414 may acquire a facial image captured by an infrared camera. Furthermore, when the information processing device 4 performs multimodal authentication including iris authentication and face authentication, the biometric information acquisition unit 414 may acquire an eye image and a facial image.

[0071] The face matching unit 4114 performs face authentication on the target person using a face image including the face of the target person. The face matching unit 4114 matches the face image of the target person with face images registered in the registered biometric information storage unit 222 (step S21). The face matching unit 4114 may match feature amounts extracted from the face image of the target person with feature amounts extracted from face images registered in the registered biometric information storage unit 222.

[0072] The authentication determination unit 4112 determines whether or not authentication is successful using the matching result by the face matching unit 4114 (step S22). If authentication is successful (step S22: Yes), the storage control unit 412 stores target information including a face image, date and time information indicating the date and time when face authentication using the face image was performed, and authentication information including an authentication score of the performed face authentication in association with the target person in the target information storage unit 421 (step S23).

[0073] The estimation unit 4131 estimates physical information about the body of the target person using target information about two or more target people related to face authentication performed at different dates and times and stored in the target information storage unit 421 (step S24). The estimation unit 4131 estimates physical information about the body of the target person using target information about two or more target people related to face authentication performed at different dates and times and stored in the target information storage unit 421. The estimation unit 4131 may estimate health information indicating a health condition as physical information. [Estimation based on a face image]

[0074] The estimation unit 4131 may detect discoloration of the facial skin from the face image. The discoloration of the facial skin may be brown. In this case, the estimation unit 4131 may estimate the possibility of an organ disease such as the liver or kidney.

[0075] The estimation unit 4131 may detect a difference between the left and right sides of the face from the face image. When the estimation unit 4131 detects a difference between the left and right sides of the face, the estimation unit 4131 may estimate the possibility of a disease related to the brain, cranial nerves, etc., including blood vessels.

[0076] The estimation unit 4131 may estimate the health state of the target person from time-series changes in the face image.

[0077] The estimation unit 4131 may estimate the health condition of the target person from the time-series change in the authentication score of the face authentication stored in the target information storage unit 221.

[0078] The output determination unit 4132 determines whether to output the estimation result (step S25). If it is determined that the estimation result should be output (step S25: Yes), the output unit 413 outputs physical information related to the body of the target person (step S26). [4-3: Technical Effects of the Information Processing Device 4]

[0079] The information processing device 4 according to the fourth embodiment can notify the target person of the health condition that can be estimated from the target person's face by using the information used for face authentication. [5: Fifth Embodiment]

[0080] Next, a fifth embodiment of an information processing device, an information processing method, and a recording medium will be described. Hereinafter, the fifth embodiment of the information processing device, the information processing method, and the recording medium will be described using an information processing device 5 to which the fifth embodiment of the information processing device, the information processing method, and the recording medium is applied. [5-1: Configuration of Information Processing Device 5]

[0081] As shown in FIG. 6 , the information processing device 5 of the fifth embodiment includes a calculation device 21 and a storage device 22, similar to the information processing device 2 of the second embodiment to the information processing device 4 of the fourth embodiment. Furthermore, the information processing device 5 of the fifth embodiment may include a communication device 23, an input device 24, and an output device 25, similar to the information processing device 2 of the second embodiment to the information processing device 4 of the fourth embodiment. However, the information processing device 5 does not need to include at least one of the communication device 23, the input device 24, and the output device 25. The information processing device 5 of the fifth embodiment differs from the information processing device 2 of the second embodiment to the information processing device 4 of the fourth embodiment in that a heart rate acquisition unit 515 is further implemented within the calculation device 21. Other features of the information processing device 5 may be the same as other features of at least one of the information processing device 2 of the second embodiment to the information processing device 4 of the fourth embodiment. Therefore, the following will describe in detail the differences from the already-described embodiments, and will omit appropriate descriptions of other overlapping features. [5-2: Information Processing Operation Performed by the Information Processing Device 5]

[0082] 7, an information processing operation performed by the information processing device 5 will be described. Fig. 72 is a flowchart showing the flow of the information processing operation performed by the information processing device 5. The information processing device 5 may start the information processing operation in response to an authentication execution instruction operation by a target person.

[0083] 7, the biometric information acquisition unit 514 acquires biometric information (step S20). The score calculation unit 2111 compares the biometric information of the target person with the biometric information registered in the registered biometric information storage unit 222 (step S21). The authentication determination unit 2112 determines whether or not authentication is successful using the comparison result by the score calculation unit 2111 (step S22).

[0084] In the fifth embodiment, if authentication is successful (step S22: Yes), the heart rate acquisition unit 515 acquires heart rate information indicating the heart rate of the target person (step S50). The heart rate acquisition unit 515 may acquire the heart rate based on a facial image. The heart rate acquisition unit 515 may acquire the heart rate based on a facial image captured for facial authentication. That is, the heart rate acquisition unit 515 may acquire the heart rate at the authentication date and time. Alternatively, the heart rate acquisition unit 515 may acquire the heart rate from a device that measures the target person's heart rate.

[0085] The target information storage unit 521 stores target information, including heart rate information and date and time information indicating the date and time when the heart rate information was acquired, in association with the target person in the target information storage unit 521 (step S51). The estimation unit 5131 estimates physical information related to the target person's body using target information for two or more target people acquired at different dates and times stored in the target information storage unit 521 (step S52). The estimation unit 5131 may detect heart rate abnormalities. The estimation unit 5131 may detect abnormalities or conditions of the target person using daily time-series changes in heart rate. The estimation unit 5131 may learn the individual's heart rate and determine whether it is high or low depending on the individual.

[0086] The output determination unit 5132 determines whether to output the estimation result (step S25). If it is determined that the estimation result should be output (step S25: Yes), the output unit 513 outputs physical information related to the body of the target person (step S26). [5-3: Technical Effects of the Information Processing Device 5]

[0087] The information processing device 5 according to the fifth embodiment can notify a target person of a health condition related to the heart rate by acquiring the heart rate. [6: Sixth Embodiment]

[0088] Next, a sixth embodiment of an information processing device, an information processing method, and a recording medium will be described. Hereinafter, the sixth embodiment of the information processing device, the information processing method, and the recording medium will be described using an information processing device 6 to which the sixth embodiment of the information processing device, the information processing method, and the recording medium is applied. [6-1: Configuration of Information Processing Device 6]

[0089] As shown in FIG. 8 , the information processing device 6 of the sixth embodiment includes a calculation device 21 and a storage device 22, similar to the information processing device 2 of the second embodiment to the information processing device 5 of the fifth embodiment. Furthermore, the information processing device 6 of the sixth embodiment may include a communication device 23, an input device 24, and an output device 25, similar to the information processing device 2 of the second embodiment to the information processing device 5 of the fifth embodiment. However, the information processing device 6 does not need to include at least one of the communication device 23, the input device 24, and the output device 25. The information processing device 6 of the sixth embodiment differs from the information processing device 2 of the second embodiment to the information processing device 5 of the fifth embodiment in that the authentication unit 611 further includes a liveness determination unit 6115. Other features of the information processing device 5 may be the same as other features of at least one of the information processing device 2 of the second embodiment to the information processing device 4 of the fourth embodiment. Therefore, hereinafter, differences from the already-described embodiments will be described in detail, and descriptions of other overlapping features will be omitted as appropriate. [6-2: Information Processing Operation Performed by Information Processing Device 6]

[0090] The information processing operation performed by the information processing device 6 will be described with reference to Fig. 9. Fig. 9 is a flowchart showing the flow of the information processing operation performed by the information processing device 6. The information processing device 6 may start the information processing operation in response to an authentication execution instruction operation by the target person.

[0091] 9, the biometric information acquisition unit 614 acquires biometric information (step S60). The biometric information acquisition unit 614 may acquire an image of the target person to be used for matching and body temperature information indicating the body temperature of the target person. The biometric information acquisition unit 614 may acquire an image of the target person to be used for matching and body temperature information indicating the body temperature of the target person at the same time. The information processing device 6 may have a temperature measurement mechanism. For example, a body temperature sensor may be provided near the camera.

[0092] In the sixth embodiment, the liveness determination unit 6115 performs liveness determination. The liveness determination unit 6115 may determine whether the biometric information acquisition unit 614 has acquired an image of a living target person. The liveness determination unit 6115 may perform liveness determination using body temperature information indicating the body temperature of the target person. The liveness determination unit 6115 may also perform liveness determination using biometric information such as a face image or an eye image acquired by the biometric information acquisition unit 614. Furthermore, the information processing device 6 may determine, for example, whether the body temperature is such that entry into a restricted area is permitted.

[0093] The score calculation unit 6111 calculates an authentication score (step S61). The score calculation unit 6111 may calculate the authentication score based on the result of matching biometric information and the result of liveness determination.

[0094] The authentication determination unit 6112 determines whether or not the authentication is successful using the authentication score calculated by the score calculation unit 6111 (step S62). If the authentication is successful (step S62: Yes), the storage control unit 612 associates the target information, including the biometric information and authentication information related to the authentication using the biometric information, with the target person and stores it in the target information storage unit 621 (step S63). The storage control unit 612 associates the target information, including the body temperature information and date and time information indicating the date and time when the body temperature information was acquired with the target person and stores it in the target information storage unit 621.

[0095] The estimation unit 6131 estimates physical information about the target person's body using two or more pieces of target information about the target person acquired on different dates and times and stored in the target information storage unit 621 (step S64). The estimation unit 6131 may estimate the target person's normal body temperature. The normal body temperature may have a range. For example, the estimation unit 6131 may estimate the target person's normal body temperature to be 36.0 to 37.0 degrees Celsius, etc. Normal body temperature varies from person to person. The estimation unit 6131 may learn normal body temperatures that vary from person to person and estimate abnormal body temperature according to individual differences. Furthermore, normal body temperature may vary depending on the season, date and time, etc. The estimation unit 6131 may also learn normal body temperature using information such as the season and date and time. The estimation unit 6131 may estimate abnormality when the body temperature acquired from the target person differs from the normal body temperature by a predetermined amount or more.

[0096] The output determination unit 6132 determines whether to output the estimation result (step S25). If it is determined that the estimation result should be output (step S25: Yes), the output unit 613 outputs physical information about the target person's body (step S26). If the body temperature indicated by the body temperature information is 40 degrees or higher, the output unit 613 may recommend that the target person visit a medical institution regardless of whether the target person has a high body temperature.

[0097] In the sixth embodiment, a case where liveness determination is performed using the temperature of the target person has been described, but the body temperature may be acquired without performing liveness determination. In this case, for example, the biometric information acquisition unit 614 may acquire the body temperature from a device that measures the body temperature of the target person. The biometric information acquisition unit 614 may acquire the body temperature from a wearable device equipped with a body temperature measurement mechanism worn by the target person. In this case, the body temperature may be acquired at predetermined time intervals. [6-3: Technical Effects of Information Processing Device 6]

[0098] The information processing device 6 in the sixth embodiment can notify a target person of a health condition related to the body temperature by acquiring the body temperature. [7: Seventh embodiment]

[0099] Next, a seventh embodiment of an information processing device, an information processing method, and a recording medium will be described. Hereinafter, the seventh embodiment of the information processing device, the information processing method, and the recording medium will be described using an information processing device 7 to which the seventh embodiment of the information processing device, the information processing method, and the recording medium is applied. [7-1: Configuration of Information Processing Device 7]

[0100] As shown in FIG. 10 , the information processing device 7 of the seventh embodiment includes a calculation device 21 and a storage device 22, similar to the information processing device 2 of the second embodiment to the information processing device 6 of the sixth embodiment. Furthermore, the information processing device 7 of the seventh embodiment may include a communication device 23, an input device 24, and an output device 25, similar to the information processing device 2 of the second embodiment to the information processing device 6 of the sixth embodiment. However, the information processing device 7 does not necessarily include at least one of the communication device 23, the input device 24, and the output device 25. The information processing device 7 of the seventh embodiment differs from the information processing device 2 of the second embodiment to the information processing device 6 of the sixth embodiment in that the output unit 713 further includes a reference change unit 7133. Other features of the information processing device 7 may be the same as other features of at least one of the information processing device 2 of the second embodiment to the information processing device 6 of the sixth embodiment. Therefore, the following will describe in detail the differences from the already-described embodiments, and will omit appropriate descriptions of other overlapping features. [7-2: Information Processing Operation Performed by the Information Processing Device 7]

[0101] The output unit 713 outputs physical information about the target person's body according to the time period when the target person was authenticated. The criteria change unit 7133 may change the criteria for determining whether or not to output physical information about the target person's body according to the time period when the target person was authenticated. The criteria change unit 7133 may change the criteria stored in the criteria storage unit 723 according to the time period indicated by the date and time information.

[0102] The criterion changing unit 7133 may change the criterion for determining whether or not to output physical information if the time period during which the target person is authenticated is different from usual. For example, if the target person is authenticated late at night a predetermined number of times or more within a predetermined period, the criterion changing unit 7133 may lower the criterion for outputting a message indicating poor health, making it easier to output a message indicating poor health. Alternatively, the criterion changing unit 7133 may raise the criterion to avoid overlooking important matters.

[0103] Furthermore, the criterion changing unit 7133 may change, depending on the time period when the target person is authenticated, a predetermined threshold value to be compared with the authentication score used by the authentication assessment unit 2112. For example, since eyes are often not open in the morning, when using an eye image captured in the morning, a process may be performed to compensate for a decrease in the authentication score due to the eyes not being open.

[0104] The estimation unit 7131 may determine the activity tendency of the target person based on the time when authentication was performed. In this case, the criterion changing unit 7133 may change the criterion for determining whether or not to output physical information based on the activity tendency of the target person.

[0105] The estimation unit 7131 may estimate whether the target person is sleeping well or not based on the time period when the target person is authenticated. The estimation unit 7131 may also detect whether the target person has been drinking alcohol based on time-series changes in the stored images. For example, in the case of authentication when going to work, if the target person has been drinking alcohol, the estimation unit 7131 may notify the manager. [7-3: Technical Effects of the Information Processing Device 7]

[0106] The information processing device 7 in the seventh embodiment can improve user convenience by taking into account the time zone during authentication, thereby suppressing false refusals during authentication and changing the notification criteria for physical information.

[0107] Next, an eighth embodiment of an information processing device, an information processing method, and a recording medium will be described. Hereinafter, the eighth embodiment of the information processing device, the information processing method, and the recording medium will be described using an information processing device 6 to which the eighth embodiment of the information processing device, the information processing method, and the recording medium is applied. [8-1: Configuration of Information Processing Device 6]

[0108] As shown in FIG. 11 , the information processing device 6 of the eighth embodiment includes a calculation device 21 and a storage device 22, similar to the information processing device 2 of the second embodiment to the information processing device 7 of the seventh embodiment. Furthermore, the information processing device 6 of the eighth embodiment may include a communication device 23, an input device 24, and an output device 25, similar to the information processing device 2 of the second embodiment to the information processing device 7 of the seventh embodiment. However, the information processing device 6 does not necessarily have to include at least one of the communication device 23, the input device 24, and the output device 25. The information processing device 6 of the eighth embodiment differs from the information processing device 2 of the second embodiment to the information processing device 7 of the seventh embodiment in that a notification content registration unit 824 and a notification destination registration unit 825 are further implemented in the storage device 22. Other features of the information processing device 6 may be the same as at least one other feature of the information processing device 2 of the second embodiment to the information processing device 7 of the seventh embodiment. Therefore, the following will describe in detail the differences from the already-described embodiments, and will omit appropriate descriptions of other overlapping features. [8-2: Information Processing Operation Performed by Information Processing Device 6]

[0109] The notification destination registration unit 825 registers a target person and a recipient who receives the target person's physical information in association with each other. The recipient may be a person related to the target person. The recipient may be a person close to the target person, a manager at the target person's workplace, etc. The recipient may be designated by the target person. The recipient may be designated by the application location of the information processing device 6. The notification destination registration unit 825 may store the recipient's contact information for each target person, as exemplified in Table 3 below. The contact information may be, for example, an email address. [Table 3: Notification destination registration unit 825]

[0110]

[0111] In the example shown in Table 3 above, the notification destination registration unit 825 has registered therein "P1U", which is the contact information for recipient "U" who will receive the physical information of target person P1, and "P1V", which is the contact information for recipient "V". Also, "P2W", which is the contact information for recipient "W" who will receive the physical information of target person P2, has also been registered. Also, "P3X", which is the contact information for recipient "X", "P3Y", which is the contact information for recipient "Y", and "P3Z", which is the contact information for recipient "Z", who will receive the physical information of target person P3, have also been registered.

[0112] In the eighth embodiment, in step S25 in FIG. 3, the output unit 813 outputs the physical information of the target person to the recipient who receives the physical information of the target person in a predetermined case. The notification content registration unit 824 may store notification content corresponding to items for each recipient, as exemplified in Table 4 below. [Table 4: Notification Content Registration Unit 824]

[0113]

[0114] In the example shown in Table 4 above, the notification content registration unit 824 stores information indicating that the same content as that notified to the target person P1 will be notified to the recipient "U" who receives the physical information of the target person P1 for item A. That is, when the output unit 813 notifies the target person P1 for item A, it also notifies the recipient "U". The notification content registration unit 824 also stores information indicating that the recipient "U" will be notified for item B if the level is "4" or higher. That is, the output unit 813 also notifies the recipient "U" for item B if the level is "4" or higher. The notification content registration unit 824 also stores information indicating that the recipient "U" will be notified of only the item content and level for item C. That is, the output unit 813 notifies the recipient "U" of only the item content and level for item C. The notification content registration unit 824 also stores information indicating that the recipient "U" does not need to be notified of item D. That is, in either case, the output unit 813 does not notify the recipient "U" of item D. [8-3: Technical Effects of Information Processing Device 6]

[0115] The information processing device 6 in the eighth embodiment notifies recipients, such as the family members of the target person, of the physical information of the target person, and can therefore be used for monitoring purposes. [9: Ninth embodiment]

[0116] Next, a ninth embodiment of an information processing device, an information processing method, and a recording medium will be described. Hereinafter, the ninth embodiment of the information processing device, the information processing method, and the recording medium will be described using an information processing device 9 to which the ninth embodiment of the information processing device, the information processing method, and the recording medium is applied. [9-1: Configuration of Information Processing Device 9]

[0117] As shown in FIG. 12 , the information processing device 9 of the ninth embodiment includes a calculation device 21 and a storage device 22, similar to the information processing device 2 of the second embodiment to the information processing device 6 of the eighth embodiment. Furthermore, the information processing device 9 of the ninth embodiment may include a communication device 23, an input device 24, and an output device 25, similar to the information processing device 2 of the second embodiment to the information processing device 6 of the eighth embodiment.

Other features of the information processing device 9 may be the same as at least one other feature of the information processing device 6 of the second embodiment to the information processing device 6 of the eighth embodiment. Therefore, in the following, only the differences from the embodiments already described will be described in detail, and the description of other overlapping parts will be omitted as appropriate. [9-2: Information Processing Operation Performed by Information Processing Device 9]

[0118] The information processing operation performed by the information processing device 9 will be described with reference to Fig. 13. Fig. 13 is a flowchart showing the flow of the information processing operation performed by the information processing device 9. The information processing device 9 may start the information processing operation in response to an authentication execution instruction operation by the target person. [Notification to medical institution]

[0119] As shown in FIG. 13A, the biometric information acquisition unit 214 acquires biometric information (step S20). The score calculation unit 2111 compares the biometric information of the target person with the biometric information registered in the registered biometric information storage unit 222 (step S21). The authentication determination unit 2112 determines whether authentication is successful or not using the comparison result by the score calculation unit 2111 (step S22). If authentication is successful (step S22: Yes), the storage control unit 212 associates target information including the biometric information and authentication information related to authentication using the biometric information with the target person and stores it in the target information storage unit 221 (step S23). The estimation unit 2131 estimates physical information related to the target person's body using two or more pieces of target information related to authentications performed on different dates and times for the target person stored in the target information storage unit 221 (step S24).

[0120] The output determination unit 9132 determines whether or not it is a predetermined case in which the physical information should be output to a medical institution where the target person will be treated (step S90). The predetermined case may be, for example, when the level of any item is "4" or higher. The predetermined case may be set by the target person. The predetermined case may be specified by the target person. The predetermined case may be specified by the target person's family. If the information processing device 9 is applied to entrance and exit of a workplace, the predetermined case may be specified by the workplace. If it is a predetermined case (step S90: Yes), the output unit 913 outputs the physical information to a medical institution where the target person will be treated. The output unit 913 outputs the physical information to the medical institution and requests a diagnosis using the physical information.

[0121] The medical institution registration unit 926 registers the target person and the medical institution where the target person will be treated in association with each other. The medical institution registration unit 926 may store contact information for the medical institution in charge of each item for each target person, as shown in Table 5 below. [Table 5: Medical Institution Registration Unit 926]

[0122]

[0123] In the example shown in Table 5 above, the medical institution registration unit 926 has "DA" registered as the contact information for the medical institution responsible for item A of the target person P1, "DB" registered as the contact information for the medical institution responsible for item B, "DC" registered as the contact information for the medical institution responsible for item C, and "DD" registered as the contact information for the medical institution responsible for item D.

[0124] The output unit 913 may transmit the information used to estimate the target person's physical information to the corresponding contact information registered in the medical institution registration unit 926. The information used to estimate the target person's physical information may be the target information, and the output unit 913 may transmit an image of the target person and a log of various numerical values. The output unit 913 may also provide a log of the food the target person purchased at a convenience store, the exercises they performed at a fitness gym, etc. [Feedback from medical institutions]

[0125] 13(b), the diagnostic information acquisition unit 915 acquires diagnostic information including a diagnosis result from the medical institution that received the target information in step S91 (step S92). The diagnostic information may include the contents of a diagnosis made by the medical institution based on the target information regarding the items estimated by the estimation unit 2131. The diagnostic information may also include items discovered as a result of deriving from the items estimated by the estimation unit 2131.

[0126] The output unit 913 notifies the target person of the diagnostic information and the billing information (step S93). In the ninth embodiment, information may be notified to a person other than the target person, as in the eighth embodiment. The output unit 913 may notify the target person and recipients other than the target person of the diagnostic information and the billing information depending on the situation. Furthermore, the output unit 913 may not notify the target person of the diagnostic information, but may notify recipients other than the target person of the diagnostic information depending on the situation.

[0127] The diagnostic information may include a prescription, or the computing device 21 may further implement a mechanism for arranging for the delivery of the medicine prescribed by the doctor to the person's home.

[0128] Furthermore, if the doctor determines that a medical interview is necessary, a mechanism for coordinating the schedule of the subject and the doctor may be further implemented within the computing device 21. The medical interview may be conducted online.

[0129] The payment control unit 916 settles the medical expenses (step S94). The medical institution registration unit 926 may store a debit account for each item for each subject, as exemplified in Table 5 above. In the example shown in Table 5 above, the medical institution registration unit 926 may register "Account 1" as the debit account for item A of subject P1, "Account 2" as the debit account for item B, "Account 1" as the debit account for item C, and "Account 1" as the debit account for item D. The payment control unit 916 may settle the costs incurred for the diagnosis based on the information registered in the medical institution registration unit 926.

[0130] Although an example has been given in which a medical institution and a debit account can be registered for each item, one medical institution and one account may be registered for a target person. Furthermore, for example, if the target person is a child, the account of another person, such as the target person's guardian, may be registered as the debit account. Furthermore, in this embodiment, an example is given in which payment is made directly from an account, but in addition to or instead of payment being made directly from an account, card payment using a credit card or the like may also be performed. Furthermore, code payment using a smartphone or the like may also be performed.

[0131] The medical institution may also be determined by the administrator of the information processing device 9. For example, if the information processing device 9 is applied to an apartment building, the apartment building may appoint a dedicated doctor. [9-3: Technical Effects of the Information Processing Device 9]

[0132] The information processing device 9 in the ninth embodiment can diagnose without conducting a medical interview, and if treatment is possible by prescribing medicine, the target person can automatically receive treatment. The information processing device 9 can contribute to early detection of illness. [10: Supplementary Note]
