[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] An information processing device, an information processing method, and a recording medium according to a first embodiment will be described below. The information processing device, the information processing method, and the recording medium according to the first embodiment will be described below using an information processing device 1 to which the information processing device, the information processing method, and the recording medium according to the first embodiment are 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 a code output unit 11 and an iris information registration unit 12.

[0012] The code output unit 11 outputs a subject code to the subject when registering the subject's face information or when face authentication of the subject is successful at least in one of the cases. When registering the subject's iris information, if the subject inputs a subject code, the iris information registration unit 12 registers the iris information collected from the subject in association with identification information that can identify the subject and the registered face information of the subject. [1-2: Technical Effects of Information Processing Device 1]

[0013] When registering iris information of a subject, if the subject inputs a subject code, the information processing device 1 in the first embodiment registers the iris information in association with identification information and face information, so that the iris information of the subject can be reliably associated with information that can identify the subject, thereby preventing registration of iris information by someone impersonating the subject. [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 information processing device 2]

[0015] 2 is a block diagram 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 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 provided 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 operations to be performed by the information processing device 2 are realized within the arithmetic device 21. That is, the arithmetic device 21 can function as a controller for realizing logical functional blocks for executing the operations (in other words, processing) that the information processing device 2 should perform.

[0017] 2 shows an example of logical functional blocks implemented in the arithmetic device 21 to perform information processing operations. As shown in FIG. 2, implemented in the arithmetic device 21 are a code output unit 211 which is a specific example of a "code output means" described in the appendix described later, an iris information registration unit 212 which is a specific example of an "iris information registration means" described in the appendix described later, an alert output unit 213 which is a specific example of an "alert output means" described in the appendix described later, a face image acquisition unit 214, a face information registration unit 215, a face authentication unit 216, and an iris image acquisition unit 217. However, the arithmetic device 21 does not necessarily have to include at least one of the alert output unit 213, the face image acquisition unit 214, the face information registration unit 215, the face authentication unit 216, and the iris image acquisition unit 217. Details of the operation of each of the code output unit 211, iris information registration unit 212, alert output unit 213, face image acquisition unit 214, face information registration unit 215, face authentication unit 216, and iris image acquisition unit 217 will be described later with reference to Figure 3.

[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 random access memory (RAM), a read-only memory (ROM), a hard disk device, a magneto-optical disk device, a solid-state drive (SSD), and a disk array device. In other words, the storage device 22 may include a non-transitory recording medium. The storage device 22 may store a biometric information DB 221. In the second embodiment, the biometric information DB 221 may be a database that associates identification information capable of identifying a subject, facial information of the subject, and iris information of the subject. However, the storage device 22 does not have to store the biometric information DB 221.

[0019] The communication device 23 can communicate with devices external to the information processing device 2 via a communication network (not shown). The information processing device 2 may transmit and receive signals via the communication device 23 to and from a mobile terminal carried by the subject.

[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 (for example, 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: Iris Information Registration Operation Performed by Information Processing Device 2]

[0022] Next, the iris information registration operation performed by the information processing device 2 in the second embodiment will be described with reference to Fig. 3. Fig. 3 is a diagram showing the flow of the iris information registration operation performed by the information processing device 2 in the second embodiment.

[0023] FIG. 3A is a diagram showing a flow of an iris information registration operation performed by the information processing device 2 according to the second embodiment when registering facial information. As shown in FIG. 3A, the facial information registration unit 215 registers facial information of the subject (step S20). The facial information is information used for facial authentication of the subject. The facial information may be facial features extracted from a facial image of the subject. The facial image acquisition unit 214 may acquire a facial image generated by capturing an image of the subject's face. The facial image of the subject may be captured by a camera mounted on a mobile device carried by the subject, and the facial image acquisition unit 214 may acquire the facial image from the mobile device carried by the subject via the communication device 23. In this case, at the timing of acquiring the facial image, the information processing device 2 may acquire a destination, such as the subject's telephone number or email address, for sending information to the subject. The facial information registration unit 215 may register the facial information of the subject in the biometric information DB 221 in association with identification information that can identify the subject. The facial information of the subject registered in the biometric information DB 221 may be used for facial authentication of the subject.

[0024] The code output unit 211 issues a subject code to the subject (step S21). The subject code is a code issued when registering face information in order to prevent impersonation when registering iris information after registering face information. The subject code may be, for example, a code associated with identification information that can identify the subject. The code output unit 211 may transmit the subject code to a mobile terminal carried by the subject via the communication device 23.

[0025] 3(b) is a diagram showing the flow of the iris information registration operation performed by the information processing device 2 in the second embodiment when performing face authentication. As shown in FIG. 3(b), the face authentication unit 216 performs face authentication of the subject (step S22). The face image acquisition unit 214 acquires a face image of the subject, and the face authentication unit 216 may extract face information from the acquired face image and compare it with face information registered in the biometric information DB 221. The face authentication unit 216 determines whether face authentication is successful (step S23).

[0026] If the facial authentication is successful (step S23: Yes), the code output unit 211 issues a subject code to the subject (step S24). The code output unit 211 may, for example, transmit the subject code via the communication device 23 to a destination of information for the subject acquired when the facial image was registered. If the facial authentication is unsuccessful (step S23: No), for example, the facial authentication unit 216 may perform facial authentication again.

[0027] Fig. 3(c) is a diagram showing the flow of the iris information registration operation performed by the information processing device 2 in the second embodiment when registering iris information. The operation shown in Fig. 3(c) is performed after the operation shown in at least one of Fig. 3(a) and Fig. 3(b).

[0028] As shown in FIG. 3(c), the iris information registration unit 212 determines whether or not it is a registration scene for iris information (step S25). Iris information is information used for iris authentication of the subject. The registration scene for iris information may be a scene in which the subject is about to register iris information. For example, the iris information registration unit 212 may determine that the subject is about to register iris information when it detects that the subject is in front of an iris camera that captures an iris image. The iris information may be an iris image including the iris of the subject. The iris information may be iris feature amounts extracted from the iris image of the subject.

[0029] If it is a time to register iris information (step S25: Yes), the iris information registration unit 212 determines whether or not the subject has input a subject code (step S26). The subject code is the subject code issued by the code output unit 211 in step S21 of FIG. 3(a) and step S24 of FIG. 3(b). If the subject has input a subject code (step S26: Yes), the iris image acquisition unit 217 collects the iris information of the subject. The iris information registration unit 212 registers the iris information in association with identification information that can identify the subject and the registered face information of the subject (step S27). The iris information of the subject registered in the biometric information DB 221 may be used for iris authentication of the subject. The iris image acquisition unit 217 may acquire an iris image via the communication device 23 from an iris camera that captures an image of the iris of the subject. The iris image acquisition unit 217 may extract iris feature amounts as iris information from the iris image.

[0030] If the subject inputs a code different from the subject code (step S26: No), the alert output unit 213 outputs an alert to the subject (step S28). Furthermore, if the subject inputs a code different from the subject code, the iris information registration unit 212 does not register the iris information of the subject in association with identification information that can identify the subject and the registered face information of the subject. [2-3: Technical Effects of Information Processing Device 2]

[0031] The information processing device 2 in the second embodiment outputs an alert to the subject when a code different from the subject code issued when registering and authenticating face information is input, thereby making it possible to reliably associate the iris information of the subject with information that can identify the subject. Also in the second embodiment, when registering iris information to be used for iris authentication of the subject, if the subject inputs a subject code, the iris information is registered in association with identification information and face information, making it possible to reliably associate the iris information of the subject with information that can identify the subject. This makes it possible to prevent iris information from being registered by someone impersonating the subject. [3: Third embodiment]

[0032] 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 information processing device 3]

[0033] The configuration of the information processing device 3 in the third embodiment will be described with reference to Fig. 4. Fig. 4 is a block diagram showing the configuration of the information processing device 3 in the third embodiment.

[0034] As shown in FIG. 4 , the information processing device 3 of the third embodiment includes a calculation device 21 and a storage device 22, similar to the information processing device 2 of the second embodiment. Furthermore, the information processing device 3 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. However, the information processing device 3 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 3 of the third embodiment differs from the information processing device 2 of the second embodiment in that the calculation device 21 further includes a candidate image registration unit 318 and the storage device 22 further includes a candidate image DB 322. The candidate image DB 322 may be a database that associates identification information that can identify a subject with a facial image of the subject. However, the storage device 22 does not necessarily have to store the candidate image DB 322. Other features of the information processing device 3 may be the same as those of the information processing device 2 of the second embodiment. Therefore, in the following, only the parts that differ from the embodiments already described will be described in detail, and the description of other overlapping parts will be omitted as appropriate. [3-2: Iris Information Registration Operation Performed by Information Processing Device 3]

[0035] The iris information registration operation performed by the information processing device 3 in the third embodiment will be described with reference to Fig. 5. Fig. 5 is a diagram showing the flow of the iris information registration operation performed by the information processing device 3 in the third embodiment.

[0036] 5(a), the facial image acquisition unit 214 captures an image of the face of the subject to be face-recognized and acquires the generated facial image (step S30). The facial image of the subject may be captured by a camera mounted on a portable terminal carried by the subject, and the facial image acquisition unit 214 may acquire the facial image from the portable terminal carried by the subject via the communication device 23.

[0037] The face authentication unit 216 performs face authentication using the face image acquired in step S30 (step S31). The candidate image registration unit 318 determines whether or not the face authentication in step S31 is successful (step S32). If the face authentication is successful (step S32: Yes), the candidate image registration unit 318 determines whether or not the iris information of the subject has yet been registered in the biometric information DB 221 (step S33). If the iris information of the subject has not yet been registered (step S33: Yes), the candidate image registration unit 318 determines whether or not the iris region of the face image acquired in step S30 has a quality equal to or greater than a predetermined quality (step S34).

[0038] If the iris region has a quality equal to or higher than a predetermined quality (step S34: Yes), the candidate image registration unit 318 registers the face image acquired in step S30 as a candidate image for extracting iris information (step S35). The candidate image registration unit 318 may associate the face image acquired in step S30 with identification information that can identify the subject, and register the face image in the candidate image DB 322 as a candidate image for extracting iris information. That is, the candidate image registration unit 318 registers the face image as a candidate image for extracting iris information if (1) the face authentication of the subject is successful (step S32: Yes), (2) the iris information of the subject is not registered (step S33: Yes), and (3) the iris region of the face image has a quality equal to or higher than a predetermined quality (step S34: Yes). On the other hand, if any of the determinations in steps S32, S33, and S34 is negative, the process may return to step S30, for example.

[0039] The candidate image registration unit 318 issues a confirmation code to the subject (step S36). The confirmation code may be, for example, a code associated with identification information that can identify the subject. The candidate image registration unit 318 may, for example, transmit the subject code via the communication device 23 to a destination of information for the subject that was acquired when the facial image was registered. After the operation of step S36, the candidate image registration unit 318 may wait for the subject to input a confirmation code.

[0040] 5(b), the candidate image registration unit 318 determines whether or not a confirmation code has been input (step S37). The candidate image registration unit 318 may repeat this step until a confirmation code is input.

[0041] If the confirmation code is input (step S37: Yes), the iris information registration unit 212 extracts iris information from the candidate image (step S38). The iris information registration unit 212 may extract iris information from the candidate image registered in the candidate image DB 322 at the time the confirmation code is input.

[0042] The iris information registration unit 212 registers the extracted iris information in association with the identification information and face information (step S39). The iris information registration unit 212 may register the extracted iris information in the biometric information DB 221 in association with the identification information and face information. [3-3: Technical Effects of Information Processing Device 3]

[0043] The information processing device 3 in the third embodiment can simply register iris information without capturing an iris image for registering the iris information. Furthermore, when a confirmation code is input, the information processing device 3 registers iris information extracted from a face image, so that iris information can be simply registered while ensuring that the iris information of the person in question is reliably registered. [4: Fourth embodiment]

[0044] 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 information processing device 4]

[0045] The configuration of the information processing device 4 in the fourth embodiment will be described with reference to Fig. 6. Fig. 6 is a block diagram showing the configuration of the information processing device 4 in the fourth embodiment.

[0046] As shown in FIG. 6 , 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 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 4 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 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 calculation device 21 further includes an iris authentication unit 419 and a payment unit 420. In other words, the information processing device 4 is a device capable of performing multimodal authentication of face authentication and iris authentication. Other features of the information processing device 4 may be the same as those of the information processing device 2 in the second embodiment or the information processing device 3 in the third embodiment. Therefore, in the following, only the parts that differ from the embodiments already described will be described in detail, and the description of other overlapping parts will be omitted as appropriate. Although not described here, the information processing device 4 in the fourth embodiment may register iris information in the biometric information DB 221 by the same operation as at least one of the information processing device 2 in the second embodiment and the information processing device 3 in the third embodiment. [4-2: Information processing operation performed by information processing device 4]

[0047] Next, the information processing operation performed by the information processing device 4 in the fourth embodiment will be described with reference to Fig. 7. Fig. 7 is a diagram showing the flow of the information processing operation performed by the information processing device 4 in the fourth embodiment.

[0048] 7, the face authentication unit 216 performs face authentication of the subject (step S40). The face image acquisition unit 214 acquires a face image of the subject, and the face authentication unit 216 may extract face information from the acquired face image and compare it with face information registered in the biometric information DB 221.

[0049] The iris authentication unit 419 performs iris authentication of the subject (step S41). The iris image acquisition unit 217 acquires an iris image of the subject, and the iris authentication unit 419 may extract iris information from the acquired iris image and compare it with iris information registered in the biometric information DB 221. Alternatively, if the iris region of the face image used for face authentication has a predetermined or higher quality, the iris authentication unit 419 may extract iris information from the iris region of the face image and compare it with iris information registered in the biometric information DB 221.

[0050] The settlement unit 420 determines whether the face authentication in step S40 and the iris authentication in step S41 are successful (step S42). The settlement unit 420 executes the settlement if at least one of the face authentication and the iris authentication is successful.

[0051] If either the face authentication or the iris authentication is successful (step S42: one is successful), the settlement unit 420 performs a first settlement operation (step S43). If both the face authentication and the iris authentication are successful (step S42: both are successful), the settlement unit 420 performs a second settlement operation (step S44). That is, the settlement unit 420 performs different settlement-related operations depending on whether (i) either the face authentication or the iris authentication is successful or (ii) both the face authentication and the iris authentication are successful.

[0052] The second payment may be a payment that is made when authentication accuracy is higher than that of the first payment, and therefore may be a payment that is preferable to the subject. For example, the second payment may have a wider range of possible payments than that of the first payment. For example, the second payment may be awarded with more points than that of the first payment. Also, for example, the payment amount of the second payment may be discounted compared to that of the first payment. [4-3: Technical Effects of Information Processing Device 4]

[0053] The information processing device 4 in the fourth embodiment operates differently regarding payment depending on the authentication method, and therefore the services that a target person can receive can be changed depending on the authentication method. When authentication is performed using multiple modalities, authentication accuracy increases, and therefore more services can be provided to a target person authenticated by a method with high authentication accuracy. [5: Fifth embodiment]

[0054] 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]

[0055] The configuration of the information processing device 5 in the fifth embodiment will be described with reference to Fig. 8. Fig. 8 is a block diagram showing the configuration of the information processing device 5 in the fifth embodiment.

[0056] As shown in FIG. 8 , 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 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 necessarily 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 the calculation device 21 further includes a permission unit 521. Other features of the information processing device 5 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 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. Although the explanation will be omitted, the information processing device 5 in the fifth embodiment may register iris information in the biometric information DB 221 by the same operation as at least one of the information processing device 2 in the second embodiment and the information processing device 3 in the third embodiment. [5-2: Admission permission operation performed by information processing device 5]

[0057] Next, the admission permission operation performed by the information processing device 5 in the fifth embodiment will be described with reference to FIGS.

[0058] FIG. 9 is a diagram illustrating the admission permission given to a first subject P1 by an information processing device 5 in the fifth embodiment. The first subject P1 has a first role. The first role may be, for example, a secretary to a company executive.

A camera C and an iris camera IC are installed near the entrance E, and the information processing device 5 may be capable of performing both face authentication and iris authentication.

[0059] 9(b) is a diagram showing the flow of the operation of permitting entry to the first subject P1 performed by the information processing device 5 in the fifth embodiment. As shown in FIG. 9(b), the face authentication unit 216 performs face authentication of the first subject P1 (step S50). The face image acquisition unit 214 may acquire a face image of the first subject P1 captured by a camera C installed near the entrance E. The face authentication unit 216 may extract face information from the acquired face image and compare it with face information registered in the biometric information DB 221.

[0060] The iris authentication unit 419 performs iris authentication of the first subject P1 (step S51). The iris image acquisition unit 217 may acquire an iris image of the first subject P1 captured by an iris camera IC provided near the entrance E. The iris authentication unit 419 may extract iris information from the acquired iris image and compare it with iris information registered in the biometric information DB 221. Alternatively, if the iris region of the face image used for face authentication has a predetermined or higher quality, the iris authentication unit 419 may extract iris information from the iris region of the face image and compare it with iris information registered in the biometric information DB 221.

[0061] The permission unit 521 determines whether or not both the face authentication in step S50 and the iris authentication in step S51 are successful (step S52). If both the face authentication in step S50 and the iris authentication in step S51 are successful (step S52: Yes), the permission unit 521 grants permission to the first target person P1 to enter the specific area SA (step S53), as shown in Fig. 9(a). If at least one of the face authentication in step S50 and the iris authentication in step S51 fails (step S52: No), the process may return to step S50, for example.

[0062] FIG. 10 is a diagram illustrating admission permission for a second target person P2 performed by the information processing device 5 in the fifth embodiment. The second target person P2 is associated with the first target person P1 and has a second role.

The first target person P1 having the first role may be in a position to undertake more time-consuming tasks compared to the second target person P2 having the second role. The second role may be, for example, a company executive. The second target person P2 may be a company executive associated with the first target person P1 who is a secretary. FIG. 10(a) is a conceptual diagram illustrating an example of a second scenario to which the information processing device 5 in the fifth embodiment is applied. As shown in FIG. 10(a), the information processing device 5 may grant admission permission to the second target person P2 who wishes to enter a specific area SA at an entrance E of the specific area SA. As in the example of the first scene, a camera C and an iris camera IC are installed near the entrance E, and the information processing device 5 may be capable of performing both face authentication and iris authentication.

[0063] 10(b) is a diagram showing the flow of the entry permission operation for the second target person P2 performed by the information processing device 5 in the fifth embodiment. As shown in FIG. 10(b), the permission unit 521 determines whether the first target person P1 has been granted entry permission (step S54). That is, the permission unit 521 determines whether the first target person P1 has succeeded in both face authentication and iris authentication. If the first target person P1 has not been granted entry permission (step S54: No), the process may return to step S54, for example.

[0064] If the first subject P1 has been granted entry permission (step S54: Yes), the face authentication unit 216 performs face authentication on the second subject P2 (step S55). The face image acquisition unit 214 may acquire a face image of the second subject P2 captured by a camera C installed near the entrance E. The face authentication unit 216 may extract face information from the acquired face image and compare it with face information registered in the biometric information DB 221.

[0065] The permission unit 521 determines whether or not the face authentication of the second target person P2 is successful (step S56). If the face authentication of the second target person P2 is successful (step S56, Yes), the permission unit 521 grants the second target person P2 permission to enter the specific area SA (step S57), as shown in FIG. 10(a). If the face authentication in step S55 is unsuccessful (step S56: No), the process may return to step S55, for example.

[0066] FIG. 11 is a diagram illustrating a first example of admission permission for a specially treated person PV performed by the information processing device 5 in the fifth embodiment. The specially treated person PV has a third role. The specially treated person PV having the third role may be a person who does not belong to the organization to which the first person P1 and the second person P2 belong. The third role may be a customer who can receive special treatment. FIG. 11(a) is a conceptual diagram illustrating an example of a third scene to which the information processing device 5 in the fifth embodiment is applied. As shown in FIG. 11(a), the information processing device 5 may grant admission permission to a specially treated person PV who wants to enter a specific area SA at an entrance E of the specific area SA. As in the examples of the first and second scenes, a camera C and an iris camera IC are installed near the entrance E, and the information processing device 5 may be capable of performing both face authentication and iris authentication.

[0067] 11(b) is a diagram showing a first flow of the operation of permitting admission to a specially treated person PV performed by the information processing device 5 in the fifth embodiment. As shown in FIG. 11(b), the permission unit 521 determines whether or not the first person P1 has been granted admission permission (step S58). That is, the permission unit 521 determines whether or not the first person P1 has succeeded in both face authentication and iris authentication. If the first person P1 has not been granted admission permission (step S58: No), the process may return to step S58, for example.

[0068] If the first target person P1 has been granted admission permission (step S58: Yes), the permission unit 521 determines whether the special treatment target person PV is within a predetermined range PA that includes the first target person P1 (step S59). If the special treatment target person PV is not within the predetermined range PA that includes the first target person P1 (step S59: No), for example, the process may return to step S59.

[0069] If the special treatment recipient PV exists within the predetermined range PA including the first target person P1 (step S59: Yes), as shown in FIG. 11(a), the permission unit 521 grants the special treatment recipient PV permission to enter the specific area SA (step S60). The permission unit 521 may determine that a person existing within the predetermined range PA including the first target person P1 is a person who may be allowed to enter the specific area SA together with the first target person P1. The special treatment recipient PV may enter the specific area SA together with the first target person P1. If there are multiple special treatment recipients PV existing within the predetermined range PA including the first target person P1, the permission unit 521 may grant permission to enter the specific area SA to the multiple special treatment recipients PV. The number of people who may enter the specific area SA together with the first target person P1 may be set in advance.

[0070] Fig. 12 is a diagram illustrating a second example of admission permission to a specially treated person PV performed by the information processing device 5 in the fifth embodiment. Fig. 12(a) is a conceptual diagram illustrating an example of a fourth scene to which the information processing device 5 in the fifth embodiment is applied.

[0071] 12(b) is a diagram showing a second flow of the operation of permitting entry to a specially treated person PV performed by the information processing device 5 in the fifth embodiment. As shown in FIG. 12(b), the permission unit 521 determines whether the second person P2 has been granted entry permission (step S58'). That is, the permission unit 521 determines whether the first person P1 has succeeded in both face authentication and iris authentication, and whether the second person P2 has succeeded in face authentication. If the second person P2 has not been granted entry permission (step S58': No), the process may return to step S58', for example.

[0072] If the second target person P2 has been granted admission permission (step S58': Yes), the permission unit 521 determines whether the special treatment target person PV is within a predetermined range PA that includes the second target person P2 (step S59'). If the special treatment target person PV is not within a predetermined range PA that includes the second target person P2 (step S59': No), the process may return to step S59', for example.

[0073] If the special treatment recipient PV is present within a predetermined range PA that includes the second person P2 (step S59': Yes), the permission unit 521 grants the special treatment recipient PV permission to enter the specific area SA (step S60'), as shown in Figure 12(a). The special treatment recipient PV can enter the specific area SA together with the second person P2. [5-3: Technical Effects of Information Processing Device 5]

[0074] The information processing device 5 in the fifth embodiment associates the second target person P2 with the first target person P1, and thereby, when granting the second target person P2 permission to enter the specific area SA, can reduce the burden imposed on the second target person P2 compared to the first target person P1. Furthermore, when the special treatment target person PV is present within a predetermined range PA that includes at least one of the first target person P1 and the second target person P2, the information processing device 5 grants the special treatment target person PV permission to enter the specific area SA, thereby reducing the burden imposed on the special treatment target person PV. The information processing device 5 can satisfy both the need for hospitality toward the special treatment target person PV and improved security. [6: Sixth embodiment]

[0075] 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]

[0076] The configuration of the information processing device 6 in the sixth embodiment will be described with reference to Fig. 13. Fig. 13 is a block diagram showing the configuration of the information processing device 6 in the sixth embodiment.

[0077] As shown in FIG. 13 , 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 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 necessarily 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 calculation device 21 further includes a generation unit 622 and a selection control unit 624. Furthermore, the information processing device 6 of the sixth embodiment transmits and receives information to and from a camera C and multiple iris camera ICs via the communication device 23.

[0078] Camera C may be installed so as to be able to image a predetermined space in order to image the subject, and may image the predetermined space. Camera C may be installed in a position that makes it easy to capture the eyes of an average person. Camera C may be installed at a height of, for example, 2.5 meters. Camera C may be installed so as to be able to image the subject from above.

[0079] Each of the plurality of iris camera ICs captures an image of the iris of the subject and generates an iris image. The plurality of iris camera ICs may be installed in different locations so that they can capture images of different locations.

[0080] Other features of the information processing device 6 may be the same as at least one other feature of the information processing device 2 in the second embodiment to the information processing device 5 in the fifth embodiment. Therefore, hereinafter, only the parts that are different from the already-described embodiments will be described in detail, and other overlapping parts will not be described as appropriate. Note that, although not described here, the information processing device 6 in the sixth embodiment may register iris information in the biometric information DB 221 by the same operation as at least one of the information processing device 2 in the second embodiment and the information processing device 3 in the third embodiment. [6-2: Authentication-related operations performed by information processing device 6]

[0081] Next, the authentication-related operation performed by the information processing device 6 in the sixth embodiment will be described with reference to Fig. 14. Fig. 14 is a diagram showing the flow of the authentication-related operation performed by the information processing device 6 in the sixth embodiment.

[0082] 14, the face image acquisition unit 214 acquires a face image of the subject to be iris-authenticated (step S60). The face image acquisition unit 214 may acquire the face image of the subject from the camera C via the communication device 23.

[0083] The generation unit 622 generates gaze information of the subject based on the face image acquired in step S60. The gaze information may be information that specifies the positions of characteristic features around the eyes, such as the inner corners of the eyes, outer corners of the eyes, and pupils, which are necessary for gaze detection. By specifying the positions of characteristic features around the eyes, the generation unit 622 may calculate the direction of the subject's gaze relative to the optical axis direction of camera C and include it in the gaze information. Furthermore, the generation unit 622 may calculate the distance between the subject and camera C by specifying the distance between the subject's eyes in the face image and include it in the gaze information.

[0084] Alternatively, the camera C may be equipped with the function of the generation unit 622, and the facial image of the subject acquired by the facial image acquisition unit 214 may include gaze information generated by the generation unit 622. The gaze information acquisition unit 623 acquires gaze information (step S61).

[0085] The selection control unit 624 selects one of the plurality of iris camera ICs based on the line-of-sight information (step S62). The selection control unit 624 may select an iris camera IC that is suitable for capturing an image of the subject's iris from the plurality of iris camera ICs based on information indicating the direction of the subject's line of sight included in the line-of-sight information.

[0086] The selection control unit 624 controls the selected iris camera IC to capture an image of the iris of the subject (step S63). When the subject and the selected iris camera IC have an appropriate positional relationship based on information indicating the distance between the subject and camera C, which is included in the line of sight information, the selection control unit 624 may control the selected iris camera IC via communication device 23 to capture an image of the iris of the subject.

[0087] The iris image acquisition unit 217 may acquire an iris image of the iris of the subject from the selected iris camera IC, and the iris authentication unit 419 may perform iris authentication of the subject using the acquired iris image.

[0088] The information processing device 6 may simultaneously detect the gaze of each of a plurality of subjects and simultaneously control the capture of iris images of each of the plurality of subjects. [6-3: Technical Effects of Information Processing Device 6]

[0089] The information processing device 6 in the sixth embodiment acquires gaze information of the subject, selects an iris camera IC from multiple iris camera ICs based on the gaze information, and causes the selected iris camera IC to capture the image, thereby reducing the processing load on the iris camera IC. The information processing device 6 can acquire an iris image in which the subject's gaze is in the appropriate direction, without providing a mechanism such as an eye-catching device near the iris camera IC to direct the subject's gaze, and without making the subject aware that an iris image is being acquired. [7: Seventh embodiment]

[0090] 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]

[0091] The configuration of the information processing device 7 in the seventh embodiment will be described with reference to Fig. 15. Fig. 15 is a block diagram showing the configuration of the information processing device 7 in the seventh embodiment.

[0092] As shown in FIG. 15 , 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 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 calculation device 21 further includes an estimation unit 725, a position control unit 726, a subject-related information registration unit 727, and a tracking unit 728. Furthermore, similar to the information processing device 6 of the sixth embodiment, the information processing device 7 of the seventh embodiment transmits and receives information to and from a camera C and multiple iris camera ICs via the communication device 23. Other features of the information processing device 7 may be the same as at least one other feature of the information processing device 2 in the second embodiment to the information processing device 6 in the sixth embodiment. Therefore, hereinafter, only the parts that are different from the already-described embodiments will be described in detail, and other overlapping parts will not be described as appropriate. Note that, although not described here, the information processing device 7 in the seventh embodiment may register iris information in the biometric information DB 221 by the same operation as at least one of the information processing device 2 in the second embodiment and the information processing device 3 in the third embodiment. [7-2: Application example of information processing device 7]

[0093] Next, an example of a situation in which the information processing device 7 in the seventh embodiment is applied will be described with reference to Fig. 16. Fig. 16 is a conceptual diagram showing an example of a situation in which the information processing device 7 in the seventh embodiment is applied. The information processing device 7 in the seventh embodiment may be used for tracking people in marketing, entrance / exit management, etc.

[0094] Camera C may be installed so as to be able to capture an image of a predetermined space in order to capture an image of the subject, and may capture the image of the predetermined space. Camera C may be installed at a height of, for example, 2.5 meters. If camera C is installed at a position higher than the height of an average person, the image captured by camera C is likely to include not only the subject's face area and upper body area, but also the subject's entire body area. Camera C may be installed so as to be able to capture an image of the entire scene to which the seventh embodiment is applied from a bird's-eye view.

[0095] Each of the plurality of iris camera ICs may be installed in a location where a target person can easily focus their attention. For example, if the seventh embodiment is applied to a store, the iris camera ICs may be installed on a product display shelf. [7-3: Authentication-related operations performed by the information processing device 7]

[0096] Next, an authentication-related operation performed by the information processing device 7 in the seventh embodiment will be described with reference to Fig. 17. Fig. 17 is a diagram showing the flow of the authentication-related operation performed by the information processing device 7 in the seventh embodiment. [7-3-1: First operation]

[0097] 17, the estimation unit 725 determines whether the iris authentication of the subject has been successful (step S70). If the iris authentication has failed (step S70: No), the process may return to step S70. For example, if the seventh embodiment is applied to a store, the initial iris authentication may be performed at the entrance of the store.

[0098] If the iris authentication is successful (step S70: Yes), the estimation unit 725 estimates the subject position PP of the subject, whose individual is identified by the iris authentication, based on the iris information used for the iris authentication (step S71). In the seventh embodiment, the iris information may include information indicating the distance between the subject and the iris camera IC, calculated by identifying the distance between the subject's eyes in the iris image. Also, in the seventh embodiment, the iris information may include the direction of the subject's gaze relative to the optical axis direction of the iris camera IC, calculated by identifying characteristic points around the eyes. In this case, the estimation unit 725 may estimate the subject position PP of the subject based on the information indicating the distance between the subject and the iris camera IC and the direction of the subject's gaze.

[0099] The position control unit 726 controls the imaging so as to generate an image of the area PPA including the position of the target person (step S72). The position control unit 726 may control the camera C via the communication device 23 so as to generate an image of the area PPA including the position of the target person.

[0100] The subject-related information registration unit 727 detects a subject-related area including at least one of the subject's face area, the worn item area, and the attached item area at the subject's position in the image, and registers the subject-related information about the subject-related area in association with the registered iris information of the subject (step S73). The subject-related information registration unit 727 may register the subject-related information in the biometric information DB 221 in association with the registered iris information of the subject.

[0101] In the seventh embodiment, the biometric information DB 221 may be a database that associates subject-related information in addition to identification information that can identify a subject, the subject's face information, and the subject's iris information. The subject-related information may be information for determining that the subjects are the same person. The subject-related area may be an area that includes at least information that can identify a subject present in a scene to which the seventh embodiment is applied. For example, worn items such as clothing, glasses, and accessories such as a watch can be useful information for identifying a person present in a certain space-time.

[0102] The tracking unit 728 tracks the subject whose iris authentication has been successful (step S74). When not controlled by the position control unit 726, the camera C may capture an image in a state where it overlooks the entire scene to which the seventh embodiment is applied. The tracking unit 728 may identify the subject from people included in the image using subject-related information registered in the biometric information DB 221. The camera C may capture a video. The tracking unit 728 may sequentially acquire, as images, multiple image frames that make up the video captured by the camera C. The tracking unit 728 may track the subject based on a subject-related region of the subject detected from the image. [7-3-2: Operation after the second time]

[0103] The estimation unit 725 may determine whether or not iris authentication of the subject is successful even during the tracking operation by the tracking unit 728. For example, if iris authentication using iris information extracted from an iris image captured by an iris camera IC installed in a location other than the store entrance is successful (step S70: Yes), the estimation unit 725 estimates the subject's position PP of the subject (step S71). The operation of the estimation unit 725 from the second time onwards may be an operation of re-specifying the subject's position PP. If the position of the subject tracked by the tracking unit 728 differs from the subject's position PP estimated by the estimation unit 725, that is, even if tracking by the tracking unit 728 fails, tracking of the subject can be continued by the operation of the estimation unit 725 re-specifying the subject's position PP.

[0104] The position control unit 726 controls the imaging to generate an image of the area PPA including the subject position (step S72). The subject-related information registration unit 727 detects a subject-related area within the image and registers subject-related information related to the subject-related area in association with the iris information of the registered subject (step S73). Each piece of subject-related information collected at different locations is registered in association with identification information that can identify the subject, so that all subject-related information acquired at different locations can be managed as information about the same subject. Each time iris authentication is successful, the amount of subject-related information that can be determined to be the same person can be increased. [7-3: Technical Effects of Information Processing Device 7]

[0105] The information processing device 7 in the seventh embodiment can accurately track the behavior of the subject in a predetermined area based on the subject-related information that can determine that the subject is the same person each time iris authentication is successful. Even if tracking of the subject based on the subject-related area fails, tracking of the subject can be continued by performing iris authentication again. [8: Note]
