[0013] Hereinafter, specific embodiments to which the present invention is applied will be described in detail with reference to the drawings. However, the present invention is not limited to the following embodiments. In addition, in order to clarify the description, the following description and drawings are appropriately simplified. In each drawing, the same components are given the same reference numerals, and the description is appropriately omitted.

[0014] FIG. 1 is a block diagram showing the configuration of an information processing device 1 according to an embodiment. The information processing device 1 performs identity authentication of a subject, and generates information related to the subject's health (hereinafter, referred to as health information). The information processing device 1 performs identity authentication by performing iris authentication using the subject's iris. For iris authentication, iris data (feature amount) calculated from iris characteristics unique to each subject is used. Specifically, the information processing device 1 performs iris authentication using the radial pattern of the subject's iris.

[0015] As shown in Fig. 1, the information processing device 1 includes an acquisition unit 2, an identification unit 3, an authentication unit 4, and a generation unit 5. The acquisition unit 2 acquires a first image suitable for authentication processing using the iris of a subject from an imaging device. The first image is an image of a part of a person's face including the subject's eye area. "Suitable for authentication processing using the iris" means that the first image is suitable for acquiring iris data to be used when performing iris authentication.

[0016] The identification unit 3 identifies an iris image corresponding to the iris region and a skin image corresponding to the skin region from the first image. The iris data can be generated from each pixel value of the iris image included in the first image. A representative example of iris data that can be used for iris authentication is data called an iris code. The iris code is data obtained by image processing of the iris image. The iris code is biometric information unique to an individual, and becomes data that can be used for authentication when the iris image is captured with appropriate quality.

[0017] The iris code can be generated, for example, by including the following steps (1) to (4). (1) detecting an eye region of a subject from a first image; (2) A step of detecting the upper eyelid edge, the lower eyelid edge, the boundary between the pupil and the iris (hereinafter referred to as the inner iris circle), and the boundary between the iris and the white of the eye (hereinafter referred to as the outer iris circle) from within the detected eye region. (3) A step of expanding the pattern in the area where the iris is captured (iris image) into bands. (4) A step of encoding the developed pattern and generating features.

[0018] An iris image refers to the donut-shaped area between the inner and outer iris circles. Note that this donut-shaped area may be hidden by the eyelids or eyelashes. In order for iris data to be usable for authentication, the quality of the iris data must satisfy a predetermined standard for authentication using iris data. If the acquired iris data does not sufficiently represent the unique characteristics of an individual, the iris data cannot be said to be usable for authentication.

[0019] For this reason, the first image is required to be free of factors that would impede the acquisition of iris data. Examples of factors that would impede the acquisition of iris data include the following: Most of the iris is hidden by the eyelids -Unacceptable degree of concealment of the iris by the eyelashes - The iris is hidden due to light reflection, etc. - Images may be blurred due to vibration of the imaging device or the subject's movement. The iris image does not meet the required resolution

[0020] Therefore, the imaging device for capturing the first image for obtaining the iris image is required to satisfy certain imaging setting conditions so as not to fall under the above factors. Regarding the resolution of the iris image, it is said that a resolution of about 500 dips is ideal to obtain iris data that can be used for authentication. In other words, the first image is required to satisfy the conditions regarding the zoom magnification of the imaging device that are compatible with authentication processing based on the iris image.

[0021] Furthermore, in order to obtain iris data that can be used for authentication, the first image is required to include the entire eye (from the inner corner to the outer corner), and to include a specified area (approximately 70%) or more of the iris. In other words, the first image is required to satisfy conditions regarding the area of ​​the iris that are compatible with authentication processing based on an iris image. The shooting setting conditions of the imaging device may include conditions regarding the lens, aperture, zoom magnification, etc., in order to satisfy such conditions regarding resolution and area.

[0022] The authentication unit 4 performs authentication processing of the subject based on the iris image. For example, the authentication unit 4 performs identity authentication of the subject by matching the above-mentioned iris data with matching data. The matching data is the iris data of the subject that is stored in advance for authentication.

[0023] After authenticating the subject, the generating unit 5 generates health information of the subject based on the skin image. Here, the health information is information about a living body that can be measured from the skin image, such as heart rate, blood pressure, and percutaneous arterial oxygen saturation (hereinafter referred to as oxygen saturation). In addition, the degree of stress, emotions, and the like may be further estimated based on one or more of the generated heart rate, blood pressure, and oxygen saturation. The estimated degree of stress, emotions, and the like may then be treated as health information.

[0024] The generating unit 5 can generate such information based on information indicating changes in the state of the body surface from, for example, successive skin images (video data) of the subject. One example of information indicating changes in the state of the body surface is, for example, a change in color of the body surface based on the blood flow of the subject. Each frame of the video data capturing the subject may include a change in color of the subject's body surface.

[0025] The oxygen saturation level is a percentage of the amount of hemoglobin in the blood that is bound to oxygen. When light is applied to the body surface, the reflected light intensity changes over time due to the fluctuation in the amount of hemoglobin in the blood vessels. For example, the generating unit 5 can estimate the oxygen saturation level by analyzing the video data of the subject and observing the change over time in the reflected light intensity.

[0026] Next, the process performed by the information processing device 1 will be described with reference to Fig. 2. Fig. 2 is a flowchart showing an information processing method performed by the information processing device 1 according to the embodiment.

[0027] First, the information processing device 1 acquires a first image suitable for authentication processing using the iris of a subject from an imaging device (S11). As described above, the first image is suitable for acquiring iris data used in iris authentication. Next, the information processing device 1 identifies an iris image corresponding to the iris region and a skin image corresponding to the skin region from the first image (S12).

[0028] Then, the information processing device 1 performs authentication processing of the subject based on the iris image (S13). The information processing device 1 also generates health information of the subject based on the skin image (S14). Thus, according to the information processing device 1 according to the embodiment, it is possible to perform authentication processing and observation of the health condition of the subject by acquiring only one image suitable for authentication processing using the iris of the subject from one imaging device. This makes it possible to realize low costs.

[0029] In addition, by generating the subject's health information using a high-quality skin image identified from an image that matches the authentication process, it becomes possible to determine the subject's health condition more accurately. In addition, the subject can easily perform both identity authentication and health condition observation by simply capturing a part of the face, including the eye area, with an imaging device without performing complicated operations.

[0030] The information processing device 1 includes a processor, a memory, and a storage device, which are not shown in the figure. The storage device stores a program that causes a computer to execute each process of the information processing method according to the embodiment. The processor loads the program from the storage device into the memory and executes the program. In this way, the processor realizes the functions of an acquisition unit 2, an identification unit 3, an authentication unit 4, and a generation unit 5.

[0031] Each of the components of the information processing device 1 may be realized by dedicated hardware. Also, some or all of the components of each device may be realized by a general-purpose or dedicated circuit, processor, or a combination of these. These may be configured by a single chip, or may be configured by multiple chips connected via a bus. Some or all of the components of each device may be realized by a combination of the above-mentioned circuits, etc., and a program. Also, a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), an FPGA (Field-Programmable Gate Array), a quantum processor (quantum computer control chip), etc. may be used as a processor.

[0032] In addition, when some or all of the components of the information processing device 1 are realized by a plurality of devices, circuits, etc., the plurality of devices, circuits, etc. may be centrally arranged or distributed. FIG. 3 is a block diagram showing a configuration of an information processing system 101 according to an embodiment. As shown in FIG. 3, the information processing system 101 includes an acquisition unit 102, a specification unit 103, an authentication unit 104, and a generation unit 105. As described above, detailed operations of each component of the information processing system 101 correspond to the operations of each component of the information processing device 1. The devices, circuits, etc. that realize each component of FIG. 3 may be realized as a client-server system, a cloud computing system, etc., each of which is connected via a communication network. In addition, the functions of the information processing device 1 may be provided in a SaaS (Software as a Service) format.

[0033] Working Example. The examples are specific examples of the above-mentioned embodiments. Fig. 4 is a block diagram showing the overall configuration of an information processing system according to the examples. As shown in Fig. 4, the information processing system 100 includes a server 10, a terminal 20, and an authentication device 30. The server 10, the terminal 20, and the authentication device 30 are each connected via a network N. Here, the network N is a wired or wireless communication line, for example, the Internet.

[0034] Here, the information processing system 100 includes a function for authenticating the identity of a subject (hereinafter referred to as an authentication function) and a function for managing the health condition of the subject (hereinafter referred to as a health management function). The information processing system 100 performs iris authentication using the iris of the subject to perform identity authentication. As will be described in detail later, matching data of the subject for authentication can be registered in advance in the authentication device 30.

[0035] <Terminal 20> The terminal 20 is an information terminal operated by a subject and transmits and receives data to and from the server 10 via the network N by wireless communication. The terminal 20 may be a personal computer, a smartphone, a tablet terminal, etc. Fig. 5 is a block diagram showing the configuration of the terminal 20 in Fig. 4.

[0036] The terminal 20 includes a camera 21, a storage unit 22, a memory 23, a communication unit 24, an input / output unit 25, and a processing unit 26. The camera 21 is an imaging device that captures images according to the control of the processing unit 26. Here, the camera 21 generates a first image that captures a part of the face of a person, including the subject's eye area. As described above, the first image is suitable for authentication processing using the subject's iris. In other words, the quality of the iris data extracted from the first image meets a predetermined standard for authentication processing.

[0037] Specifically, for example, the first image satisfies certain criteria such as no blurring of the image, a required resolution, and a condition regarding the area of ​​the iris in the first image. Therefore, the camera 21 has a function of changing the shooting setting conditions to satisfy the above-mentioned certain criteria. The shooting setting conditions may include various shooting conditions and setting conditions such as the lens, aperture, zoom, subject distance, sensitivity, and shooting mode.

[0038] Note that the camera 21 may capture an image of the entire face of the subject before capturing the first image. As will be described in detail later, the server 10 may detect the eye area from the image of the entire face of the subject. The camera 21 may zoom in on the iris position of the subject based on the detection information of the eye area from the server 10 and capture the first image.

[0039] The storage unit 22 is an example of a storage device including a non-volatile memory such as a flash memory or an SSD (Solid State Drive). The storage unit 22 stores a program in which processes including the registration process of the matching data and the transmission process of the first image described above are implemented.

[0040] The memory 23 is a volatile storage device such as a RAM (Random Access Memory), and is a storage area for temporarily holding information during operation of the processing unit 26. The communication unit 24 is a communication interface with the network N. The communication unit 24 may establish a short-range wireless communication connection and perform communication. Here, various standards such as Bluetooth (registered trademark), BLE (Bluetooth Low Energy), and UWB (Ultra-Wide Band) can be applied to the short-range wireless communication.

[0041] The input / output unit 25 includes a display device (display unit) such as a screen and an input device (input unit), and may be, for example, a touch panel. The processing unit 26 is a processor that controls the hardware of the terminal 20. The processing unit 26 loads a program from the storage unit 22 into the memory 23 and executes it. In this way, the processing unit 26 realizes the functions of a registration processing unit 261 and a transmission processing unit 262.

[0042] The registration processing unit 261 performs a pre-registration process of the matching data of the subject. This matching data is used for identity authentication of the subject. Specifically, the registration processing unit 261 transmits a registration request for an image including the iris of the subject, which is photographed by the subject, to the server 10 via the network N. As will be described later, the iris data extracted from the image for registration can be registered as matching data in the matching information DB 31 of the authentication device 30.

[0043] The transmission processing unit 262 transmits an image including the iris of the subject for registering matching data, and a first image showing a part of the face of the subject including the eye area for identity authentication and health management, to the server 10. The transmission processing unit 262 may transmit the terminal ID of the terminal 20 and the subject ID together with these pieces of information.

[0044] <Authentication device 30> The authentication device 30 is an information processing device that manages matching data of a subject and performs iris authentication to realize a personal authentication function. In response to an authentication request received from the outside, the authentication device 30 matches the iris data included in the request with matching data that it manages, and returns the matching result to the request source.

[0045] Fig. 6 is a block diagram showing the configuration of the authentication device 30 of Fig. 4. The authentication device 30 includes an authentication information DB (DataBase) 31, an iris data generating unit 32, a registration unit 33, and an authentication unit 34. The authentication information DB 31 can store matching data, which is a collection of iris features extracted from an image for registration of a subject. As shown in the example of Fig. 6, the authentication information DB 31 can store a subject ID and iris data in association with each other.

[0046] The iris data generating unit 32 generates iris data from an image including the iris of the subject. The iris data may be generated through the above-mentioned steps (1) to (4), for example. For example, the generation of the iris data includes the steps of detecting the subject's eye region from the image, identifying the iris region from the detected eye region, expanding the pattern in the iris image into a stripe shape, and encoding the expanded pattern to generate a feature. When registering the matching data, the registration unit 33 registers the matching data generated from the image for registration in the authentication information DB 31 in association with the subject ID.

[0047] Further, the iris data generating unit 32 generates iris data from the first image for personal authentication. The authentication unit 34 performs iris authentication using the iris of the subject. Specifically, the authentication unit 34 compares the iris data extracted from the first image for authentication with matching data preregistered in the authentication information DB 31. The authentication unit 34 returns to the request source as the authentication result whether or not the iris data matches the matching data. Whether or not the iris data matches corresponds to whether or not the authentication has been successful. In this way, by performing iris authentication, it is possible to prevent the subject from being confused with another person.

[0048] For example, when an authentication request is sent from the server 10, the authentication unit 34 performs authentication using iris data extracted from the first image included in the authentication request, and returns the authentication result to the server 10. When the authentication is successful, the server 10 identifies the subject associated with the matched iris data, and generates health information. In addition, the server 10 can update the health information, if any, already recorded to the latest version.

[0049] <Server 10> Server 10 is an information processing device that realizes a health management function. Server 10 may be composed of multiple servers, and each functional block may be realized by multiple computers. FIG. 7 is a block diagram showing the configuration of server 10 in FIG. 4. Server 10 includes a storage unit 11, a memory 12, a communication unit 13, and a processing unit 14. Storage unit 11 is an example of a storage device such as a hard disk or a flash memory. Storage unit 11 stores program 111 and health management DB 112. Program 111 is a computer program in which part of the health management function, etc. is implemented.

[0050] Health management DB 112 is a database that manages information related to the health of subjects. Health management DB 112 manages subject IDs and health information of subjects in association with each other. In other words, the health information and matching data used for iris authentication are linked to the subject IDs and managed by health management DB 112 of server 10 and authentication information DB 31 of authentication device 30.

[0051] The memory 12 is a volatile storage device such as a RAM, and is a storage area for temporarily holding information when the processing unit 14 is operating. The communication unit 13 is a communication interface with the network N. The processing unit 14 is a processor that controls each component of the server 10. The processing unit 14 loads a program 111 from the storage unit 11 into the memory 12, and executes the program 111. In this way, the processing unit 14 realizes the functions of an eye detection unit 141, an acquisition unit 142, an identification unit 143, an authentication processing unit 144, a generation unit 145, an output processing unit 146, and a condition change unit 147.

[0052] The eye detection unit 141 detects eye regions from a face image in which the entire face of a subject is captured and transmitted from the terminal 20. For example, a known template matching technique can be used to detect eye regions. Specifically, when the eye detection unit 141 detects a region in the face image that matches a template based on a pre-stored image of the eyes of a general person, the eye detection unit 141 specifies the detected region as an eye region. The eye detection unit 141 may detect eye regions from a face image by using a neural network constructed by machine learning.

[0053] The eye detection unit 141 transmits detection information, which detects the position of the eye area in the face image, to the terminal 20. The terminal 20 adjusts the zoom magnification of the camera 21 based on the detection information, and generates a first image zoomed in on the subject's eyes. As described above, the first image is suitable for authentication processing using the subject's iris. The acquisition unit 142 acquires the first image from the terminal 20. As described above, the first image captured by the camera 21 of the terminal 20 is transmitted to the server 10 together with the subject's ID.

[0054] The identification unit 143 can, for example, detect the eye region and facial contour of the subject from the first image, and identify the iris image and skin image in the first image based on the eye region and facial contour. As described above, in this embodiment, the iris authentication process of the subject is executed by the authentication device 30. Therefore, the authentication device 30 may identify the iris image corresponding to the iris region of the subject from the first image, and the identification unit 143 may identify the skin image corresponding to the skin region of the subject from the first image.

[0055] First, when the authentication processing unit 144 receives an image for registration from the terminal 20, it transmits a request for registration of matching data including the image to the authentication device 30. Then, the authentication processing unit 144 receives the subject ID issued when the matching data was registered from the authentication device 30. Second, when the authentication processing unit 144 receives a first image including the subject's eye area from the terminal 20, it transmits an authentication request including the image to the authentication device 30. Then, the authentication processing unit 144 receives the authentication result of the iris authentication from the authentication device 30. If the authentication is successful, the authentication processing unit 144 can identify the matched subject.

[0056] When the identification unit 143 identifies both the iris image and the skin image, the authentication processing unit 144 may transmit the iris image identified by the identification unit 143 to the authentication device 30. The generation unit 145 generates health information of the subject based on the skin image identified by the identification unit 143, and stores the generated health information in the health management DB 112 in association with the subject ID.

[0057] The process of identifying the iris image and skin image of the subject from the first image can use, for example, a known template matching technique. The identification unit 143 may identify the iris image and skin image from the first image using a neural network constructed by machine learning. The output processing unit 146 transmits the health information of the subject to the terminal 20. The terminal 20 can notify the subject of his / her own health condition by display or sound.

[0058] Fig. 8 is a diagram showing a process flow of the information processing system of the embodiment. As shown in Fig. 8, first, the terminal 20 photographs the face of the subject with the camera 21 (S101). Then, the terminal 20 outputs the face image to the server 10 (S102). The server 10 detects the eye area of ​​the subject from the face image (S103) and transmits the detection information to the terminal 20 (S104). The terminal 20 changes the shooting setting conditions based on the detection information to generate a first image (S105), and transmits the first image to the server 10 (S106).

[0059] The server 10 performs an authentication request transmission process (S107), and transmits an authentication request including the first image to the authentication device 30 (S108). Upon receiving the authentication request, the authentication device 30 extracts iris data from the first image and performs identity authentication using the iris data (S109).

[0060] Server 10 receives the authentication result from authentication device 30 (S110). If iris authentication is successful, server 10 generates health information of the subject using the skin image identified from the first image (S111). Then, server 10 can record the health information associated with the subject ID included in the authentication result in health management DB 112 (S112).

[0061] As described above, by acquiring only one image suitable for authentication processing using the iris of the subject from one camera 21, it is possible to perform authentication processing and observation of the health condition of the subject. In addition, since the skin image is identified from the image suitable for authentication processing, it can have high resolution and high image quality. By generating health information of the subject based on this skin image, it is possible to determine the health condition more accurately. In addition, the subject can easily perform both identity authentication and observation of the health condition by simply capturing an image of a part of the face including the eye area with camera 21 without performing complicated operations.

[0062] The server 10 may further include a condition change unit 147. The condition change unit 147 can change the shooting setting conditions of the imaging device so as to change the ratio of the iris area and the skin area in an image when the imaging device acquires the image. The shooting setting condition change process can be executed at any time. As an example, the condition change unit 147 can change the shooting setting conditions when the health information of the subject cannot be generated based on the skin image in S111. In this case, the condition change unit 147 can generate instruction information for changing the direction of the camera 21 so that a second image including a skin area larger than the area of ​​the skin area included in the first image can be generated. This instruction information is transmitted to the terminal 20 by the output processing unit 146.

[0063] The shooting direction of camera 21 is automatically changed according to the instruction information. The subject can take a second image with camera 21 whose shooting direction has been changed. This enables generation unit 145 to generate health information of the subject based on the skin image of this second image. Note that, based on the instruction information, input / output unit 25 of terminal 20 may be caused to notify the subject of information to change the shooting direction. The subject may manually change the shooting setting conditions of camera 21 according to the notified information.

[0064] Also, the condition change unit 147 may change, for example, the shooting setting conditions of the imaging device based on the tolerance. The tolerance is, for example, the tolerance regarding the authentication accuracy of the authentication process based on the iris image. The condition change unit 147 can generate instruction information for changing the shooting setting conditions of the imaging device according to the tolerance regarding the authentication accuracy of the authentication process based on the iris image. "The tolerance regarding the authentication accuracy of the authentication process based on the iris image is high" means that the authentication accuracy of the personal authentication may be low. Also, "The tolerance regarding the authentication accuracy of the authentication process based on the iris image is low" means that the authentication accuracy of the personal authentication is preferably high. Also, without being limited thereto, the condition change unit 147 may generate instruction information for changing the shooting setting conditions of the imaging device according to the tolerance regarding the generation of the subject's health information based on the skin image.

[0065] Generally, as an evaluation index of a biometric authentication algorithm, there are error rates of personal authentication such as false acceptance rate (FAR) and false rejection rate (FRR). The false acceptance rate is the probability that a person is erroneously recognized as the same person when biometric information of different people is matched, and the false rejection rate is the probability that a person is erroneously recognized as not the same person when biometric information of the same person is matched. These error rates are in a trade-off relationship with each other. The tolerance of the authentication accuracy of the authentication process based on the iris image can be changed, for example, by adjusting a threshold value related to the matching score of iris authentication.

[0066] Next, a method for setting the tolerance will be described. Note that this description is for setting the tolerance for the authentication accuracy of the authentication process based on an iris image, but the tolerance for the generation of the subject's health information based on a skin image can also be set manually or automatically according to the same criteria and method.

[0067] The tolerance regarding the authentication accuracy of the authentication process based on the iris image may be set by the subject via various input devices, for example, or may be automatically set according to the place of use or the environment of use. The processing unit 14 may include a tolerance determination unit (not shown). When the tolerance is automatically set according to the place of use, for example, the tolerance determination unit can automatically set the tolerance regarding the authentication accuracy of the authentication process based on the iris image based on the position information of the room or the passage where the camera 21 is installed.

[0068] The tolerance determination unit may automatically set a tolerance for the authentication accuracy of the authentication process based on the iris image according to a security level set for each room. More specifically, a security level may be associated with each room in advance and stored in the storage unit 11. The tolerance determination unit may perform processing such as acquiring the security level of the room in which the camera 21 is installed from the storage unit 11 and setting a tolerance for the authentication accuracy of the authentication process based on the iris image according to the acquired security level. Note that some or all of the functions of the tolerance determination unit may be realized by the terminal 20.

[0069] Furthermore, if the camera 21 is provided at the entrance for accessing the room, the tolerance determination unit may set the tolerance for the authentication accuracy of the authentication process based on the iris image based on the security level of the room to be accessed. For example, the tolerance determination unit may perform processing such as setting the tolerance for the authentication accuracy of the authentication process based on the iris image lower as the security level is higher.

[0070] In addition, when an entrance and an exit are separately provided for one room, the tolerance regarding the authentication accuracy of the authentication process based on an iris image set for the camera 21 set at the entrance may be different from the tolerance regarding the authentication accuracy of the authentication process based on an iris image set for the camera 21 set at the exit. For example, the tolerance determination unit can set the tolerance regarding the authentication accuracy of the authentication process based on the iris image of the camera 21 set on the entrance side of the room to be lower than the tolerance regarding the authentication accuracy of the authentication process based on the iris image of the camera 21 set on the exit side.

[0071] Also, the tolerance regarding the authentication accuracy based on the iris image set in the camera 21 may be changed when entering and leaving a room. Note that the security level is a degree of confidentiality, and in the description here, a higher security level indicates higher confidentiality.

[0072] When automatically setting according to the environment in which it is used, the tolerance determination unit can set the tolerance regarding the authentication accuracy of the authentication process based on the iris image according to, for example, the brightness of the place where the camera 21 is installed or the place where the subject is present. More specifically, the tolerance determination unit can perform processing such as lowering the tolerance regarding the authentication accuracy of the authentication process based on the iris image when the brightness is brighter or darker than a predetermined standard.

[0073] The predetermined standard is a value determined based on brightness suitable for personal authentication, and is determined according to the camera's performance and authentication algorithm. However, the predetermined standard may be arbitrarily set by the user. In addition, the tolerance determination unit may automatically determine the tolerance regarding the authentication accuracy of the authentication process based on the iris image according to the weather. For example, the tolerance determination unit may lower the tolerance regarding the authentication accuracy of the authentication process based on the iris image on a rainy day or a sunny day.

[0074] Furthermore, the tolerance regarding the authentication accuracy of the authentication process based on the iris image may be set according to the required processing speed, etc. For example, when it is desired to reduce the time required for authentication per subject, the tolerance determination unit may set the tolerance regarding the authentication accuracy of the authentication process based on the iris image high. The required processing speed may be determined based on, for example, the number of subjects who need to be authenticated. For example, when the number of people in a predetermined range or the density of people is equal to or greater than a threshold, the required processing speed is determined to be "fast". In such a case, the tolerance determination unit may set the tolerance regarding the authentication accuracy of the authentication process based on the iris image high (low authentication accuracy) so as to shorten the time required for the authentication process.

[0075] In addition, the required processing speed may be changed depending on the time of day. For example, assuming use at the entrance of an office, the number of people undergoing identity authentication is expected to temporarily increase between 8:00 a.m. and 10:00 a.m., when people arrive at work. Therefore, by setting a higher tolerance for the authentication accuracy of the authentication process based on iris images during a specific time period, the time required for identity authentication can be reduced.

[0076] If this tolerance is high, for example, the zoom magnification of the camera 21 can be lowered so that a large amount of skin image is included even if the resolution of the iris image is low. In this case, although the accuracy of personal authentication is lower, a larger area of ​​skin image can be acquired, so that the generation of the subject's health information based on the skin image can be performed more reliably. This makes it possible to prevent the need to retake images and shorten the time required for personal authentication and generation of health information.

[0077] Also, when the tolerance is low, it is possible to increase the zoom magnification of the camera 21, for example, so that the resolution of the iris image is high, although it is difficult for the skin image to be included. In this case, the accuracy of personal authentication is increased, and it is possible to reliably prevent the subject from being confused with another person.
