[0016] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. <Embodiment 1> 1 is a block diagram showing an example of an authentication terminal 10 according to embodiment 1. The authentication terminal 10 is an information processing terminal such as a smartphone or tablet carried by a subject, and performs biometric authentication of the subject in a facility such as a store. The authentication terminal 10 may also be an information processing terminal such as a tablet placed in the facility such as a store.

[0017] As shown in FIG. 1, the authentication terminal 10 includes an image acquisition unit 11, a code generation unit 12, and a reward provision unit 13.

[0018] The image acquisition unit 11 is also referred to as an image acquisition means. The image acquisition unit 11 acquires a body image generated by photographing the subject's body and a code image generated by photographing a code recording medium placed in a facility such as a store. The subject's body to be photographed is at least a part of the subject's body, such as the subject's face, fingers, eyes, ears, or palm. The authentication terminal 10 performs biometric authentication of the subject based on the body image acquired by the image acquisition unit 11. The code recording medium has a facility-side code symbol in which facility-side embedded information including at least the facility's identification information is recorded. Specifically, the code recording medium is, for example, a printed material on which a facility-side code symbol is printed on paper, plastic, or the like, and is attached to a wall, counter, or the like of the facility. The image acquisition unit 11 supplies the generated body image to the code generation unit 12 and supplies the generated code image to the reward granting unit 13.

[0019] In the present disclosure, a code symbol is a visible information code, and may be a two-dimensional code such as a barcode, a QR code (registered trademark), or a color barcode such as a Chameleon code (registered trademark). Also, in the present disclosure, a code symbol is printed or displayed based on the information of the code symbol. Here, the information of the code symbol is, for example, a predetermined number of numbers, a predetermined number of alphanumeric characters, a predetermined number of Chinese characters, or a combination thereof arranged in a line, or information in binary format.

[0020] The code generation unit 12 is also called subject-side code symbol generation means. The code generation unit 12 acquires biometric information of the subject from the body image acquired by the image acquisition unit 11, and generates subject-side embedded information including at least the biometric information. The code generation unit 12 then generates a visible subject-side code symbol based on the subject-side embedded information. The code generation unit 12 supplies the generated subject-side embedded information to the privilege granting unit 13.

[0021] The reward granting unit 13 is also referred to as a reward granting means. The reward granting unit 13 grants a reward to the subject when the facility code symbol based on the code image acquired by the image acquisition unit 11 and the subject code symbol generated by the code generation unit 12 satisfy a predetermined condition. Specifically, the reward granting unit 13 plays a game using the facility code symbol and the subject code symbol as rules, and grants a reward to the subject depending on the result of the game. For example, the reward granting unit 13 plays a matching game between the facility code symbol and the subject code symbol. Specifically, when the nth alphanumeric character (n is a positive integer) in the information of the facility code symbol matches the nth alphanumeric character in the information of the subject code symbol, the reward granting unit 13 grants a reward to the subject. Furthermore, for example, the reward granting unit 13 plays a competitive game between the facility code symbol and the subject code symbol. Specifically, if the nth, n+1th, and n+2nd digits in the information on the target person's code symbol are all greater than the nth, n+1st, and n+2nd digits in the information on the facility's code symbol, the reward granting unit 13 grants a reward to the target person. The games played by the reward granting unit 13 are not limited to these, and may be any game that uses the facility's code symbol and the target person's code symbol as rules.

[0022] Here, the benefit refers to, for example, a discount on the price of a product or service that the subject receives at the facility, a product or service that the subject receives free of charge at the facility, etc. Furthermore, granting a benefit to a subject means sending information about the benefit to a smartphone, tablet, etc. that the subject possesses, sending ticket information that displays information about the benefit to a smartphone, tablet, etc. that the subject possesses, etc.

[0023] FIG. 2 is a flowchart showing an authentication method according to the first embodiment. First, the image acquisition unit 11 of the authentication terminal 10 acquires a body image and a code image of the subject (step S10). Next, the code generation unit 12 generates a subject-side code symbol from the body image (step S11). Next, the reward granting unit 13 determines whether the facility-side code symbol and the subject-side code symbol satisfy a predetermined condition (step S12). If the reward granting unit 13 determines that the facility-side code symbol and the subject-side code symbol satisfy the predetermined condition (Yes in step S12), it grants a reward to the subject (step S13) and ends this process. On the other hand, if the reward granting unit 13 determines that the facility-side code symbol and the subject-side code symbol do not satisfy the predetermined condition (No in step S12), it ends this process.

[0024] According to the authentication terminal 10 of the first embodiment described above, the reward granting unit 13 grants a reward to the subject using the subject's code symbol and the facility's code symbol generated from the body image. This allows the subject to play a game using the subject's code symbol and the facility's code symbol as rules, and the subject can be granted a reward based on the outcome of the game. Therefore, when the subject uses the authentication terminal 10 to photograph a code recording medium having a facility's code symbol located in the facility, a fun experience can be provided to the subject, and the use of the facility's code symbol can be promoted. Furthermore, by granting a reward to the subject, the subject's purchasing motivation can be increased. This can promote the use of code symbols and increase purchasing motivation.

[0025] The authentication terminal 10 includes a processor, a memory, and a storage device (not shown). The storage device stores a computer program that implements the processing of the authentication method according to this embodiment. The processor then loads the computer program from the storage device into the memory and executes the computer program. This allows the processor to implement the functions of an image acquisition unit 11, a code generation unit 12, and a bonus granting unit 13.

[0026] Alternatively, the image acquisition unit 11, the code generation unit 12, and the bonus granting unit 13 may each be realized by dedicated hardware. Furthermore, some or all of the components of each device may be realized by general-purpose or dedicated circuits, processors, etc., or a combination of these. These may be configured by a single chip, or 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. Furthermore, a CPU (Central Processing Unit), GPU (Graphics Processing Unit), FPGA (Field-Programmable Gate Array), etc. may be used as the processor.

[0027] <Modification of the First Embodiment> Next, an authentication terminal 100 according to a modified example of the first embodiment will be described. Fig. 3 is a block diagram showing an example of the authentication terminal 100. As shown in Fig. 3, the authentication terminal 100 includes an imaging unit 110, a storage unit 120, a memory 130, a communication unit 140, an output unit 150, and a control unit 160. The authentication terminal 100 performs biometric authentication of a target user. In the following, facial authentication will be described as an example of biometric authentication, but the present invention is not limited to this.

[0028] The imaging unit 110 takes an image in accordance with the control of the control unit 160. The imaging unit 110 has a first camera 111 and a second camera 112. The first camera 111 takes an image of the face of the user in accordance with the control of the control unit 160. The second camera 112 takes an image of a code recording medium placed in the facility in accordance with the control of the control unit 160.

[0029] The storage unit 120 is a storage device that stores a program 121 for realizing each function of the authentication terminal 100. The memory 130 is a volatile storage device such as RAM, and is a storage area for temporarily storing information when the control unit 160 is operating. The communication unit 140 is a communication interface with the network.

[0030] The output unit 150 outputs the information processing result of the control unit 160. For example, the output unit 150 has a display unit 151 and an audio output unit 152. The display unit 151 is a display device that displays the information processing result of the control unit 160. The authentication terminal 100 may also include an input unit (not shown) that accepts input, and the display unit 151 and the input unit may be integrally configured like a touch panel. The audio output unit 152 includes a speaker (not shown) and outputs the information processing result of the control unit 160 by audio.

[0031] The control unit 160 is a processor, i.e., a control device, that controls each component of the authentication terminal 100. The control unit 160 loads the program 121 from the storage unit 120 into the memory 130 and executes the program 121. As a result, the control unit 160 realizes the functions of an image acquisition unit 161, a code generation unit 162, an authentication unit 163, a reward granting unit 164, an output control unit 165, and a notification unit 166.

[0032] Image acquisition unit 161 is also called image acquisition means. Image acquisition unit 161 controls first camera 111 of imaging unit 110 to capture an image of the user's face and generate a facial image for authentication that includes at least the facial region of the user. Then, image acquisition unit 161 acquires the facial image for authentication from first camera 111. Furthermore, the image acquisition unit 161 controls the second camera 112 of the imaging unit 110 to capture an image of a code recording medium placed in a facility such as a store, and to generate a code image. Then, the image acquisition unit 161 acquires the code image from the second camera 112. The image acquisition unit 161 supplies the face image for authentication to the code generation unit 162 and supplies the code image to the bonus granting unit 164.

[0033] The code generation unit 162 is also called subject-side code symbol generation means. The code generation unit 162 generates face information for user authentication from a face image for authentication. As an example, the face information may be a set of feature points extracted from the face image. Then, the code generation unit 162 generates subject-side embedded information including at least the user's face information for authentication and user identification information (user ID), and converts the subject-side embedded information into a visible subject-side code symbol. The code generating unit 162 supplies the generated target person side code symbol to the benefit providing unit 164. The code generating unit 162 also supplies the user ID and the generated face information for authentication to the authentication unit 163.

[0034] Specifically, the code generating unit 162 detects a face area included in the face image for authentication, extracts feature points from the detected face area, and sets the extracted feature point information as face information for authentication. The code generating unit 162 also acquires a user ID input by the user operating an input unit (not shown).

[0035] Then, the code generation unit 162 converts the subject-side embedded information, including the user's face information for authentication and the user ID, into a visible subject-side code symbol. For example, the code generation unit 162 converts the subject-side embedded information into a QR code symbol (QR code). The conversion into a code symbol may be performed by converting composite information, which is a composite of the face information for authentication and the user ID, into a code symbol. The conversion into a code symbol may also be performed by converting a portion of the subject-side embedded information (e.g., face information for authentication) into a parent code symbol and replacing a portion of the parent code symbol with the remaining subject-side embedded information (e.g., the user ID), thereby generating a subject-side code symbol. Note that the code generation unit 162 may encrypt the subject-side embedded information before converting it into the subject-side code symbol. This can improve the security level. In this case, the code generation unit 162 may encrypt a portion of the subject-side embedded information and not encrypt the other portion. For example, the code generating unit 162 may encrypt the face information for authentication without encrypting the user ID, or may encrypt the user ID without encrypting the face information for authentication.

[0036] In addition to the user ID, the subject-side embedded information may include payment information such as a card number required for payment, and management information such as the date and time when the facial information for authentication was photographed. The payment information may be pre-registered in the management device together with the registered facial information.

[0037] The authentication unit 163 is also called authentication means. The authentication unit 163 performs face authentication (biometric authentication) by comparing the face information for authentication generated by the code generation unit 162 with registered face information (registered biometric information) registered in advance in a management device (not shown). Note that user IDs and registered face information are registered in advance in the management device, and the authentication unit 163 controls the communication unit 140 to acquire the registered face information corresponding to the user ID from the management device. The authentication unit 163 supplies the output control unit 165 with a match in the face information. The authentication unit 163 also supplies the match in the face information and the user ID to the bonus granting unit 164 and the notification unit 166. The match in the face information corresponds to the success or failure of authentication. Note that the face information matches (match exists) when the degree of match is equal to or greater than a predetermined value.

[0038] The reward granting unit 164 is also referred to as a reward granting means. When the face authentication in the authentication unit 163 is successful, the reward granting unit 164 determines whether the facility code symbol based on the code image acquired by the image acquisition unit 161 and the subject code symbol generated by the code generation unit 162 satisfy a predetermined condition. Then, when the facility code symbol and the subject code symbol satisfy the predetermined condition, the reward granting unit 164 grants a reward to the subject. Specifically, the reward granting unit 164 plays a game using the facility code symbol and the subject code symbol as rules, and grants a reward to the subject depending on the result of the game. The specific reward granting process of the reward granting unit 164 is similar to that of the reward granting unit 13 according to the first embodiment, and therefore a description thereof will be omitted. The bonus awarding unit 164 also supplies the result of the game to the output control unit 165.

[0039] The output control unit 165 controls the output unit 150 to output the information processing result and notify the user of the information processing result. For example, the output control unit 165 causes the output unit 150 to output the face authentication result and notify the user of the face authentication result. Furthermore, the output control unit 165 may control the output unit 150 to output the subject-side code symbol and present it to the user so that it can be seen. Furthermore, the output control unit 165 may control the output unit 150 to cause the output unit 150 to output the results of the game played by the bonus awarding unit 164, thereby notifying the user of the results of the game.

[0040] The notification unit 166 is also called a notification means. If the face authentication result indicates a match in face information, that is, if the face authentication is successful, the notification unit 166 notifies the management device of the face authentication result and the user ID. The face authentication result may include the user ID. Furthermore, the notification unit 166 may transmit an error notification to the management device to the effect that face authentication has failed. Note that the notification unit 166 may include a user ID in the error notification, but is not limited to this.

[0041] 4 is a flowchart showing an example of an authentication method according to a modified example of the first embodiment. First, the image acquisition unit 161 causes the first camera 111 to photograph the user's face to acquire a facial image for authentication, and then causes the second camera 112 to read a code recording medium located in the facility and acquire a code image (step S101). Next, the code generation unit 162 generates facial information for authentication from the facial image for authentication, generates subject-side embedded information including the facial information and a user ID, and generates a subject-side code symbol (step S102). Next, the authentication unit 163 compares the facial information for authentication generated by the code generation unit 162 with registered facial information previously registered in a management device (not shown) (step S103). If the facial information matches, that is, if the degree of match between the facial information is equal to or greater than a predetermined value (Yes in step S104), the authentication unit 163 notifies the output control unit 165 that the facial information matches, and also supplies the user ID to the notification unit 166, and the process proceeds to step S105. In step S105, the notification unit 166 transmits a notification indicating that the facial authentication has been successful, including at least the user ID, to the management device (step S105). The notification unit 166 may include the facial authentication date and time (photograph date and time) in addition to the user ID in the notification. At this time, the output control unit 165 may notify the user that the facial authentication has been successful by displaying or outputting a sound on the output unit 150. Next, the reward granting unit 164 determines whether the facility-side code symbol and the subject-side code symbol satisfy a predetermined condition (step S106). If the reward granting unit 164 determines that the facility-side code symbol and the subject-side code symbol satisfy the predetermined condition (Yes in step S106), the reward granting unit 164 grants a reward to the subject (step S107) and terminates this process. On the other hand, if the reward granting unit 164 determines that the facility-side code symbol and the subject-side code symbol do not satisfy the predetermined condition (No in step S106), the reward granting unit 164 terminates this process. The output control unit 165 may notify the user of the game result by causing the output unit 150 to display or output the game result performed by the bonus awarding unit 164 in step S106. Note that the facial recognition processing in steps S103 and S104 and the code symbol matching processing in step S106 may be performed in either order, or may be performed simultaneously. If the code symbol matching processing is performed before the facial recognition processing, the code symbol matching processing is performed regardless of the result of the facial recognition.

[0042] On the other hand, if the facial information does not match, that is, if the degree of match of the facial information is less than a predetermined value (No in step S104), the authentication unit 163 supplies a message to the notification unit 166 that the facial information does not match, and ends this process. At this time, the output control unit 165 may notify the user that the facial authentication has failed by displaying or outputting a sound on the output unit 150 that the facial authentication has failed. At this time, the notification unit 166 may also transmit an error message to the management device that the facial authentication has failed.

[0043] According to the authentication terminal 100 according to the modification of the first embodiment described above, when face authentication is successful, the reward granting unit 164 grants a reward to the user using the subject's code symbol and the facility's code symbol generated from the face image for authentication. This allows the user to play a game using the subject's code symbol and the facility's code symbol as rules, and the user can be granted a reward based on the outcome of the game. Therefore, when the user uses the authentication terminal 100 to photograph a code recording medium having a facility's code symbol placed in the facility, the user can be provided with a fun experience, which can promote the use of the facility's code symbol. Furthermore, granting a reward to the user can increase the user's purchasing motivation. This can promote the use of code symbols and increase purchasing motivation.

[0044] <Embodiment 2> Next, a second embodiment of the present disclosure will be described. Fig. 5 is a diagram showing an example of an authentication terminal 100A according to the second embodiment. As shown in Fig. 5, in the authentication terminal 100A, the configurations of a code generation unit 162A and an authentication unit 163A are different from those of the authentication terminal 100 according to the modified example of the first embodiment. Therefore, a description of the configuration of the authentication terminal 100A that is the same as that of the authentication terminal 100 will be omitted.

[0045] The code generating unit 162A is also called a subject-side code symbol generating means. The code generating unit 162A generates subject-side embedded information including the face information for authentication generated by the authenticating unit 163A, and generates a visible subject-side code symbol from the subject-side embedded information. The subject-side embedded information may also include user identification information (user ID), the date and time when the face information for authentication was captured, etc. The code generating unit 162A supplies the generated target person side code symbol to the benefit providing unit 164. The specific process for generating face information and code symbols is the same as that of the code generating unit 162, and therefore a description thereof will be omitted.

[0046] The authentication unit 163A is also called an authentication means. The authentication unit 163A acquires a face image for authentication from the face image for authentication, and performs face authentication by comparing the face information for authentication with registered face information registered in advance in the management device. Furthermore, the authentication unit 163A supplies the generated face information for authentication to the code creation unit 162A. Other processing by the authentication unit 163A is the same as that by the authentication unit 163, and therefore a description thereof will be omitted.

[0047] 6 is a flowchart showing an authentication method according to the second embodiment. First, the image acquisition unit 161 causes the first camera 111 to capture a face image of the user to acquire an authentication face image, and then causes the second camera 112 to read a code recording medium located in the facility to acquire a code image (step S201). Next, the authentication unit 163A generates authentication face information from the authentication face image (step S202) and compares the authentication face information with registered face information previously registered in a management device (not shown) (step S203). If the face information matches, that is, if the degree of match between the face information is equal to or greater than a predetermined value (Yes in step S204), the authentication unit 163A supplies a notification that the face information matches to the output control unit 165, supplies the authentication face information to the code generation unit 162A, and supplies the user ID to the notification unit 166, and the process proceeds to step S205. In step S205, the notification unit 166 transmits a notification indicating that face authentication has been successful, including at least the user ID, to the management device (step S205). The notification unit 166 may include the face authentication date and time (photograph date and time) in addition to the user ID in the notification. At this time, the output control unit 165 may notify the user that face authentication has been successful by displaying or outputting a sound on the output unit 150. Next, the code generation unit 162A generates subject-side embedded information including the face information for authentication and the user ID, generates a subject-side code symbol (step S206), and proceeds to the processing of step S106 in FIG. 4.

[0048] On the other hand, if the facial information does not match, that is, if the degree of match of the facial information is less than a predetermined value (No in step S204), the authentication unit 163A supplies a message to the notification unit 166 indicating that the facial information does not match, and ends this process. At this time, the output control unit 165 may notify the user that the facial authentication has failed by displaying or outputting a sound on the output unit 150 that the facial authentication has failed. At this time, the notification unit 166 may also transmit an error message indicating that the facial authentication has failed to the management device.

[0049] According to the authentication terminal 100A according to the second embodiment described above, the same effects as those of the authentication terminal 100 can be obtained.

[0050] <Embodiment 3> Next, a third embodiment of the present disclosure will be described. Fig. 7 is a diagram showing an example of an authentication terminal 100B according to the third embodiment. As shown in Fig. 7, in the authentication terminal 100B, the configurations of an image acquisition unit 161B, a code generation unit 162B, and an authentication unit 163B are different from those of the authentication terminal 100 according to the modified example of the first embodiment. Therefore, a description of the configuration of the authentication terminal 100B that is the same as that of the authentication terminal 100 will be omitted.

[0051] The image acquisition unit 161B is also called an image acquisition means. The image acquisition unit 161B controls the first camera 111 of the imaging unit 110 in advance to capture an image of the user's face and generate a facial image for code creation that includes at least the user's facial region. Then, the image acquisition unit 161B acquires the facial image for code creation from the first camera 111. In the present disclosure, "in advance" means "before the user performs biometric authentication at a facility such as a store." For example, "in advance" may also mean "when performing user registration." Here, "performing user registration" means, for example, that the authentication terminal 100B transmits at least a user ID and facial information for registration (hereinafter referred to as "registration facial information") to a management device (not shown), and the management device stores the user ID and the registration facial information in association with each other. Similarly to image acquisition unit 161, image acquisition unit 161B controls first camera 111 of imaging unit 110 in a facility such as a store to capture an image of the user's face and acquires a face image for authentication from first camera 111. Similarly to the image acquisition unit 161, the image acquisition unit 161B controls the second camera 112 of the imaging unit 110 to capture an image of a code recording medium placed in a facility such as a store, and acquires a code image from the second camera 112. The image acquisition unit 161B supplies the face image for code creation to the code generation unit 162, supplies the face image for authentication to the authentication unit 163B, and supplies the code image to the bonus granting unit 164.

[0052] The code generating unit 162B is also called a subject-side code symbol generating means. The code generating unit 162B acquires face information for code creation from a face image for code creation in advance, generates subject-side embedding information including at least the face information, and generates a visible subject-side code symbol from the subject-side embedding information. The subject-side embedding information may also include user identification information (user ID), payment information such as a card number required for payment, and management information such as the date and time of capturing the face information for code creation. The code generating unit 162B supplies the generated target person side code symbol to the benefit providing unit 164. The specific process for generating face information and code symbols is the same as that of the code generating unit 162, and therefore a description thereof will be omitted. Furthermore, the face information for code creation generated by the code generation unit 162B may be registered in advance in the management device as registered face information. In other words, the code generation unit 162B may generate registered face information from a face image acquired for user registration, and use the registered face information as face information for code creation to generate a subject-side code symbol. At this time, the subject-side code symbol generated by the code generation unit 162B may be registered in the management device together with the registered face information.

[0053] The authentication unit 163B is also called an authentication means. The authentication unit 163B acquires a face image for authentication from the face image for authentication, and performs face authentication by comparing the face information for authentication with registered face information registered in advance in the management device. Other processing by the authentication unit 163B is the same as that of the authentication unit 163, and therefore a description thereof will be omitted.

[0054] FIG. 8 is a flowchart showing an authentication method according to the third embodiment. First, the image acquisition unit 161B causes the first camera 111 to capture a photograph of the user's face to acquire a facial image for code creation (step S301). Next, the code generation unit 162B generates facial information for code creation from the facial image for code creation, generates subject-side embedded information including the facial information and a user ID, and generates a subject-side code symbol (step S302). Next, the image acquisition unit 161B causes the first camera 111 to capture a photograph of the user's face to acquire a facial image for authentication, and causes the second camera 112 to capture a code recording medium placed in the facility to acquire a code image (step S303). Next, the authentication unit 163B generates facial information for authentication from the facial image for authentication (step S304), and proceeds to the process of step S103 in FIG. 4. In addition, if registered face information is generated from a face image acquired for user registration, a subject-side code symbol is generated using the registered face information, and the subject-side code symbol is registered in a management device together with the registered face information, the subject-side code symbol may be identified in step S106 based on the user ID sent to the management device in step S105.

[0055] The authentication terminal 100B according to the third embodiment described above can achieve the same effects as the authentication terminal 100. In the authentication terminal 100, after the user arrives at a facility such as a store, the image acquisition unit 161 acquires a facial image for authentication, and the code generation unit 162 generates a subject-side code symbol from the facial image for authentication. This may result in a waiting time until the authentication process is completed. On the other hand, the authentication terminal 100B according to the third embodiment generates a subject-side code symbol in advance, eliminating the time required to generate a subject-side code symbol at a facility such as a store, thereby reducing the waiting time until the authentication process is completed.

[0056] Furthermore, the code generating unit 162B may generate registration face information from a face image acquired for user registration, and generate a subject-side code symbol by using the registration face information as face information for creating a code. In this case, since the subject-side code symbol is generated simultaneously with user registration, there is no need for the user to have the first camera 111 of the authentication terminal 100B take a picture of their own face before going to a facility such as a store, thereby reducing hassle.

[0057] <Embodiment 4> Next, a fourth embodiment of the present disclosure will be described. Fig. 9 is a block diagram showing the overall configuration of an authentication system 200 according to a third embodiment. The authentication system 200 is a computer system that performs biometric authentication of a target user. In the following, facial authentication will be described as an example of biometric authentication, but the present disclosure is not limited to this.

[0058] Authentication system 200 includes authentication terminals 300-1 to 300-3 and management device 400. Authentication terminals 300-1 to 300-3 and management device 400 are capable of communicating with each other via network N. Network N is a wired or wireless communication line.

[0059] Each of the authentication terminals 300-1 to 300-3 has the same configuration as the authentication terminal 10 according to the first embodiment, the authentication terminal 100 according to the modified example of the first embodiment, the authentication terminal 100A according to the second embodiment, or the authentication terminal 100B according to the third embodiment. Hereinafter, when the authentication terminals 300-1, 300-2, and 300-3 are not to be distinguished from one another, they may be simply referred to as authentication terminals 300. Note that in this figure, the number of authentication terminals 300 is three, but it may be two or less, or four or more.

[0060] 10 is a block diagram showing the configuration of a management device 400 according to embodiment 4. The management device 400 includes a storage unit 410, a memory 420, a communication unit 430, and a control unit 440.

[0061] The storage unit 410 is a storage device that stores a program 411 for realizing each function of the management device 400. The memory 420 is a volatile storage device such as RAM, and is a storage area for temporarily storing information when the control unit 440 is operating. The communication unit 430 is a communication interface with the network N.

[0062] The storage unit 410 is also a storage device that stores registration information 412. As a result, the storage unit 410 is also referred to as a storage means. As shown in FIG. 11 , the registration information 412 is information in which a user ID, which is user identification information 411A, is associated with registration face information, which is registration biometric information 411B. The user ID and registration face information are transmitted in advance from the authentication terminal 300 to the management device 400. The registration information 412 may include payment information, such as a card number required for payment, associated with the user ID, and management information, such as the date and time of capturing the registration face information. In addition to the registration information 412, the storage unit 410 also stores programs for realizing each function of the management device 400.

[0063] The control unit 440 controls the hardware of the management device 400. When the control unit 440 receives a notification requesting registered face information, it transmits the registered face information corresponding to the user ID included in the notification to the authentication terminal 300. Furthermore, when the control unit 440 receives a notification of a face authentication result indicating success of face authentication from the authentication terminal 300, it may perform payment using payment information corresponding to the user ID included in the notification.

[0064] According to the authentication system 200 according to the fourth embodiment described above, it is possible to promote the use of code symbols and increase purchasing motivation.

[0065] The functions of the code generation units 12, 162, 162A, and 162B, the functions of the authentication units 163, 162A, and 163B, and the functions of the benefit granting units 13 and 164 of the authentication terminal 300 may be provided in the management device 400. In this case, the authentication terminal 300 transmits a facial image and a code image of the subject to the management device 400. Alternatively, the management device 400 may transmit a generated subject-side code symbol to the authentication terminal 300, and the output control unit 165 of the authentication terminal 300 may cause the output unit 150 to output the subject-side code symbol and present it to the user so that it can be seen. Alternatively, the management device 400 may transmit a face authentication result to the authentication terminal 300, and the output control unit 165 of the authentication terminal 300 may cause the output unit 150 to output the face authentication result, thereby notifying the user of the face authentication result. Alternatively, the management device 400 may transmit the game result to the authentication terminal 300, and the output control unit 165 of the authentication terminal 300 may cause the output unit 150 to output the game result, thereby notifying the user of the game result. Alternatively, the management device 400 may transmit information about a benefit or ticket information displaying information about a benefit to the authentication terminal 300.

[0066] <Embodiment 5> Next, an authentication system according to a fifth embodiment of the present disclosure will be described. The authentication system according to the fifth embodiment differs from the authentication system 200 according to the fourth embodiment in that it includes an authentication terminal 300A instead of the authentication terminal 300 and a management device 400A instead of the management device 400, and performs face authentication processing in the management device 400A. Therefore, among the configurations of the authentication system according to the fifth embodiment, descriptions of the configurations similar to those of the authentication system 200 will be omitted.

[0067] As shown in FIG. 12, the authentication terminal 300A includes an imaging unit 110, a storage unit 120, a memory 130, a communication unit 140, an output unit 150, and a control unit 360.

[0068] The control unit 360 is a processor, i.e., a control device, that controls each component of the authentication terminal 300A. The control unit 360 loads the program 321 from the storage unit 120 into the memory 130 and executes the program 321. In this way, the control unit 360 realizes the functions of an image acquisition unit 361, a code generation unit 362, an authentication control unit 363, a reward granting unit 364, and an output control unit 165.

[0069] The image acquisition unit 361 is also called an image acquisition means. Similar to the image acquisition unit 161, the image acquisition unit 361 acquires a face image and a code image for authentication. The image acquisition unit 361 supplies the face image for authentication to the code generation unit 362 and the authentication control unit 363 , and supplies the code image to the bonus granting unit 364 .

[0070] The code generation unit 362 is also called subject-side code symbol generation means. Like the code generation unit 162, the code generation unit 362 generates user face information from a face image for authentication. Then, the code generation unit 362 generates subject-side embedded information including at least the user face information and user identification information (user ID), and converts the subject-side embedded information into a visible subject-side code symbol. The code generating unit 362 supplies the generated target person side code symbol to the benefit providing unit 364.

[0071] The authentication control unit 363 controls the communication unit 140 to cause the management device 400A to transmit the facial image for authentication supplied from the image acquisition unit 361. Specifically, the authentication control unit 363 transmits a facial authentication request including the facial image to the management device 400A via the network N and receives a facial authentication result from the management device 400A. The authentication control unit 363 may detect the user's facial area from the facial image and include an image of the facial area in the facial authentication request. The authentication control unit 363 may also extract feature points from the facial area and include information on the extracted feature points in the facial authentication request as facial information for authentication. The authentication control unit 363 then supplies the facial authentication result to the reward granting unit 364.

[0072] The reward granting unit 364 is also called a reward granting means. Similar to the reward granting unit 164, when face authentication is successful, the reward granting unit 364 determines whether the facility side code symbol based on the code image acquired by the image acquisition unit 361 and the target person side code symbol generated by the code generation unit 362 satisfy a predetermined condition. Then, when the facility side code symbol and the target person side code symbol satisfy the predetermined condition, the reward granting unit 364 grants a reward to the target person. The specific reward granting process of the reward granting unit 364 is the same as that of the reward granting unit 164, and therefore a description thereof will be omitted. The bonus awarding unit 364 also supplies the result of the game to the output control unit 165.

[0073] 13, the management device 400A includes a storage unit 410, a memory 420, a communication unit 430, and a control unit 440A. The storage unit 410, memory 420, and communication unit 430 of the management device 400A are the same as those of the management device 400 according to the fourth embodiment, and therefore, description thereof will be omitted.

[0074] The control unit 440A is a processor, that is, a control device, that controls each component of the management device 400A. The control unit 440A loads the program 411 from the storage unit 410 into the memory 420 and executes the program 411. In this way, the control unit 440A realizes the function of the authentication unit 441.

[0075] The authentication unit 441 is also called authentication means. The authentication unit 441 acquires a face image for authentication from the face image for authentication received from the authentication terminal 300A, and performs face authentication by comparing the face information for authentication with registered face information 412B that is registered in advance in the management device 400A. The specific face authentication process is the same as that of the authentication unit 163, and therefore a description thereof will be omitted. Then, the authentication unit 441 controls the communication unit 430 to transmit the face authentication result to the authentication terminal 300A. Specifically, the authentication unit 441 specifies the identification information 412A of the user whose facial feature information matches, and transmits to the authentication terminal 300A a message indicating that the face authentication was successful and the specified identification information 412A.

[0076] FIG. 14 is a flowchart showing an authentication method according to the fifth embodiment. First, the image acquisition unit 361 of the authentication terminal 300A causes the first camera 111 to capture a user's face to acquire a facial image for authentication, and then causes the second camera 112 to record a code image on a recording medium to acquire a code image (step S401). Next, the communication unit 140 transmits the facial image for authentication to the management device 400A and issues an authentication request (step S402). Next, the authentication unit 441 of the management device 400A performs facial authentication (step S403). Specifically, the authentication unit 441 generates facial information for authentication from the facial image for authentication, compares the facial information for authentication with registered facial information 412B in the registration information 412, and determines that facial authentication has been successful if the degree of match between the facial information is equal to or greater than a predetermined value. Next, the authentication unit 441 notifies the authentication terminal 300A of an authentication result indicating whether facial authentication has been successful and identification information 412A (step S404). At this time, the authentication unit 441 may identify payment information, etc. associated with the identification information 412A from the registration information 412 and perform payment processing. Next, the output control unit 165 of the authentication terminal 300 notifies the user of the face authentication result by displaying or audibly outputting the face authentication result on the output unit 150 (step S405). If the authentication result indicates that face authentication is successful, the code generation unit 362 generates a subject-side code symbol using the face information for authentication (step S406). Next, the reward granting unit 364 compares the facility-side code symbol with the subject-side code symbol and determines whether a predetermined condition is met (step S407). Next, if the facility-side code symbol and the subject-side code symbol meet the predetermined condition, the reward granting unit 364 grants a reward to the subject (step S408), and ends this process. Note that the facial recognition processing in steps S403 and S404 and the code symbol matching processing in step S407 may be performed in any order, or may be performed simultaneously. If the code symbol matching processing is performed before the facial recognition processing, the code symbol matching processing is performed regardless of the result of the facial recognition.

[0077] According to the authentication system of the fifth embodiment described above, it is possible to promote the use of code symbols and increase purchasing motivation, similarly to the fourth embodiment.

[0078] Furthermore, although the above-described embodiments have been described as hardware configurations, the present disclosure is not limited to such configurations and may be realized by causing a processor to execute a computer program.

[0079] In the above example, the program can be stored and supplied to a computer using various types of non-transitory computer-readable media. Non-transitory computer-readable media include various types of tangible storage media. Examples of non-transitory computer-readable media include magnetic storage media (e.g., flexible disks, magnetic tapes, hard disk drives), magneto-optical storage media (e.g., magneto-optical disks), CD-ROMs (Read Only Memory), CD-Rs, CD-R / Ws, DVDs (Digital Versatile Discs), and semiconductor memories (e.g., mask ROMs, PROMs (Programmable ROMs), EPROMs (Erasable PROMs), flash ROMs, and RAMs (Random Access Memory)). The program may also be supplied to a computer by various types of transitory computer-readable media. Examples of transitory computer-readable media include electrical signals, optical signals, and electromagnetic waves. The transitory computer-readable media can be supplied to a computer via wired communication paths such as electrical wires and optical fibers, or via wireless communication paths.
