[0012] First Embodiment First, an overview and summary of the processing system 10 of this embodiment will be described using FIG. 1 . Service systems 31-34 are installed in multiple facilities operated by multiple business entities. The service systems 31-34 are systems that provide predetermined services to customers who have successfully passed customer authentication using biometric information, and the content of the services varies from facility to facility. For example, the service system 31 installed in a hotel may perform check-in and check-out processes for customers who have successfully passed customer authentication. Furthermore, the service systems 33-34 installed in a restaurant or retail store may perform accounting processes for customers who have successfully passed customer authentication. Furthermore, the service system 32 installed in a movie theater may perform ticket issuance and sales processes for customers who have successfully passed customer authentication, or may perform a process to open a gate to enter the movie theater. Note that the type of facility and the content of the processes performed for customers who have successfully passed customer authentication are merely examples and are not limited to the examples given here.

[0013] In this embodiment, the service systems 31-34 do not each perform customer authentication using biometric information, but the processing system 10 performs customer authentication collectively. That is, each facility is provided with a terminal device 20 that accepts biometric information input from customers. The terminal device 20 then transmits the input biometric information to the processing system 10. The processing system 10 performs customer authentication based on the received biometric information and returns the authentication result to the terminal device 20. The service systems 31-34 acquire the authentication result from the terminal device 20 and perform processing according to the authentication result.

[0014] Furthermore, if the processing system 10 is successful in customer authentication, it registers the facility that transmitted the biometric information in the customer's visit history information. In this way, it is possible to generate visit history information for the real store (physical store) that performed customer authentication using biometric information. Then, the processing system 10 generates information to be provided to the customer based on this visit history information and the facility attribute information.

[0015] A real store that has gone as far as to authenticate a customer using biometric information is likely to be a facility that the customer is truly interested in. The processing system 10 generates information to be provided to a customer based on visit history information of a real store that has authenticated the customer using such biometric information, making it possible to generate information (such as advertisements) targeted to the user that the user is interested in with high accuracy.

[0016] Next, an example of the hardware configuration of the processing system 10 will be described. Each functional unit of the processing system 10 is realized by any combination of hardware and software, centered around a CPU (Central Processing Unit) of any computer, memory, programs loaded into the memory, a storage unit such as a hard disk that stores the programs (this can store programs that are pre-loaded when the device is shipped, as well as programs downloaded from storage media such as CDs (Compact Discs) or servers on the Internet), and a network connection interface. Those skilled in the art will understand that there are many variations in the implementation methods and devices.

[0017] FIG. 2 is a block diagram illustrating an example of the hardware configuration of a processing system 10. As shown in FIG. 2, the processing system 10 has a processor 1A, a memory 2A, an input / output interface 3A, a peripheral circuit 4A, and a bus 5A. The peripheral circuit 4A includes various modules. The processing system 10 does not necessarily have the peripheral circuit 4A. The processing system 10 may be composed of multiple physically and / or logically separated devices, or may be composed of a single physically and / or logically integrated device. When the processing system 10 is composed of multiple physically and / or logically separated devices, each of the multiple devices may have the above hardware configuration.

[0018] The bus 5A is a data transmission path for the processor 1A, memory 2A, peripheral circuit 4A, and input / output interface 3A to transmit and receive data to and from each other. The processor 1A is an arithmetic processing device such as a CPU or a GPU (Graphics Processing Unit). The memory 2A is a memory such as a RAM (Random Access Memory) or a ROM (Read Only Memory). The input / output interface 3A includes an interface for acquiring information from an input device, an external device, an external server, an external sensor, a camera, etc., and an interface for outputting information to an output device, an external device, an external server, etc. Examples of input devices include a keyboard, a mouse, a microphone, physical buttons, a touch panel, etc. Examples of output devices include a display, a speaker, a printer, a mailer, etc. The processor 1A can issue commands to each module and perform calculations based on the results of those calculations.

[0019] Next, the functional configuration of the processing system 10 will be described. Fig. 3 shows an example of a functional block diagram of the processing system 10. As shown in the figure, the processing system 10 has an acquisition unit 11, an authentication unit 12, a history registration unit 13, a provision information generation unit 14, an output unit 15, and a storage unit 16. Note that the processing system 10 does not necessarily have to have the storage unit 16. In this case, an external device configured to be able to communicate with the processing system 10 has the storage unit 16.

[0020] The storage unit 16 stores various types of information. First, as shown in Fig. 4, the storage unit 16 stores information linking identification information of the terminal devices 20 (terminal device identification information) with identification information of the facility where each terminal device 20 is installed (facility identification information).

[0021] Furthermore, the storage unit 16 stores information linking facility identification information with attribute information of each facility, as shown in Fig. 5. Examples of the attribute information include, but are not limited to, identification information of the business entity that operates each facility (business entity identification information), the type of service provided at the facility, and information indicating the location of the facility (address).

[0022] The storage unit 16 also stores information about customers, as shown in Fig. 6. In the example shown, first customer identification information, biometric information, second customer identification information, and attribute information are linked to one another.

[0023] The first customer identification information is information for identifying a customer in the services provided by the processing system 10.

[0024] The second customer identification information is information for identifying a customer in the services provided by each of a plurality of business entities that operate each of a plurality of facilities.

[0025] Examples of biometric information include, but are not limited to, facial images, irises, fingerprints, and voiceprints.

[0026] The attribute information is information indicating the attributes of the customer, and examples thereof include, but are not limited to, gender, age, presence or absence of allergies, address, and nationality.

[0027] The storage unit 16 also stores visit history information for physical stores where customer authentication using biometric information has been performed, as shown in Figures 7 and 8. In the illustrated example, the date and time of the visit are linked to the facility identification information of the facility visited. Figure 7 shows visit history information that includes visit histories to all facilities, while Figure 8 shows visit history information that is narrowed down to only facilities operated by a certain business entity.

[0028] 3, the acquisition unit 11 acquires, from each of the multiple terminal devices 20, first identification information for identifying the facility where each terminal device 20 is installed, and the biometric information of the customer input to the terminal device 20. The first identification information is identification information of the terminal device 20 or identification information of the facility where the terminal device 20 is installed.

[0029] As explained using FIG. 1, a terminal device 20 is installed in each of a plurality of facilities. A customer who visits a facility performs an operation for customer authentication on the terminal device 20 in order to receive a predetermined service at the facility. Specifically, the customer operates the terminal device 20 and inputs his or her own biometric information. The terminal device 20 has a means for accepting input of biometric information, a means for transmitting the biometric information to the processing system 10, and a means for receiving the result of customer authentication based on the biometric information. The means for accepting input of biometric information is realized using any input device such as a camera, a fingerprint sensor, or a microphone.

[0030] The authentication unit 12 performs customer authentication based on the biometric information of the customer acquired by the acquisition unit 11. For example, the authentication unit 12 checks whether biometric information matching the biometric information of the customer acquired by the acquisition unit 11 is registered in the storage unit 16 by comparing a predetermined feature extracted from the biometric information of the customer acquired by the acquisition unit 11 with a predetermined feature extracted from the biometric information of each customer (see FIG. 6) stored in the storage unit 16. If the biometric information is registered, the authentication unit 12 determines that the customer is a legitimate customer (authentication successful), and if the biometric information is not registered, the authentication unit 12 determines that the customer is not a legitimate customer (authentication failed).

[0031] As another example, the authentication unit 12 may perform customer authentication to determine whether a customer who inputs biometric information into the terminal device 20 at a certain facility is a legitimate customer of the business entity that operates the facility. Specifically, if biometric information matching the customer's biometric information acquired by the acquisition unit 11 is registered in the storage unit 16, the authentication unit 12 refers to the information in FIG. 6 related to the customer. Then, the authentication unit 12 checks whether second customer identification information is registered in association with the business entity that operates the facility where the terminal device 20 that transmitted the customer's biometric information is installed. If registered, the authentication unit 12 determines that the customer is a legitimate customer of the business entity (authentication successful), and if not registered, the authentication unit 12 determines that the customer is not a legitimate customer of the business entity (authentication failed).

[0032] The authentication unit 12 transmits the authentication result ("authentication successful" or "authentication failed") to the terminal device 20. The service systems 31-34 installed in the facility execute processing according to the authentication result received by the terminal device 20. An example of the processing executed when customer authentication is successful is as described above (check-in processing, etc.). On the other hand, when customer authentication is successful, error processing is executed. For example, the customer is notified that customer authentication has failed via an output device such as a display or speaker.

[0033] If the customer authentication is successful, the history registration unit 13 registers the facility identified by the first identification information acquired by the acquisition unit 11 in the visit history information of the customer. Through this registration process, the visit history information as shown in Fig. 7 and Fig. 8 is updated.

[0034] The information to be provided generation unit 14 generates information to be provided to a customer based on visit history information (see FIGS. 7 and 8) and facility attribute information (see FIG. 5). The information to be provided generation unit 14 can further generate information to be provided to a customer based on customer attribute information (see FIG. 6). The information to be provided generation unit 14 can generate, for example, an advertisement as information to be provided.

[0035] For example, the information to be provided generation unit 14 may estimate customer preferences based on attribute information of the visited facilities indicated in the visit history information or attribute information of the customer. Then, the information to be provided generation unit 14 may generate advertisements that match the customer preferences based on the estimation results. The method of estimating preferences and the method of generating advertisements that match each preference may be realized using any technology.

[0036] The information to be provided generating unit 14 may also ascertain the current location of the customer based on the visit history information. Then, the information to be provided generating unit 14 may generate advertisements for facilities in the vicinity of the current location (e.g., facilities within a predetermined distance from the current location) as information to be provided to the customer. The information to be provided may also generate advertisements for facilities in the vicinity of the current location that match the estimated customer preferences as information to be provided to the customer. The information to be provided generating unit 14 may also generate information to be provided to the customer based on the attributes of the facility that the customer visited first or last, or the order in which the customer visited each facility.

[0037] The output unit 15 provides the customer with the information to be provided generated by the information to be provided generation unit 14. The output unit 15 may provide the customer with the information to be provided, for example, via an application installed on the customer's mobile terminal (e.g., a smartphone, a tablet terminal, a smartwatch, a mobile phone, etc.), or may provide the information to the customer by other means.

[0038] Next, an example of the processing flow of the processing system 10 will be described with reference to the flowchart of Fig. 9. When the acquisition unit 11 receives the biometric information of the customer and the first identification information for identifying the terminal device 20 from the terminal device 20, the processing of Fig. 9 is executed.

[0039] First, the authentication unit 12 performs customer authentication based on the customer's biometric information acquired by the acquisition unit 11 (S10), and transmits the authentication result to the terminal device 20 (S11). The service systems 31-34 of each facility execute processing according to the authentication result.

[0040] Next, if the customer authentication is successful (Yes in S12), the history registration unit 13 updates the visit history information of the customer (S13). Specifically, the history registration unit 13 registers the facility identified by the first identification information acquired by the acquisition unit 11 in the visit history information of the customer. Then, the process ends.

[0041] On the other hand, if the customer authentication fails (No in S12), the visit history information is not updated and the process ends.

[0042] Next, the effects of the processing system 10 of this embodiment will be described. The processing system 10 can generate visit history information for a real store where customer authentication using biometric information has been performed. Then, the processing system 10 generates information to be provided to the customer based on such visit history information and facility attribute information.

[0043] A real store that has gone as far as to authenticate a customer using biometric information is likely to be a facility that the customer is truly interested in. The processing system 10 generates information to be provided to a customer based on visit history information of a real store that has authenticated the customer using such biometric information, making it possible to generate information (such as advertisements) targeted to the user that the user is interested in with high accuracy.

[0044] In addition, the processing system 10 manages the biometric information of each customer, and also manages information that integrates the customer identification information in the services provided by the processing system 10 with the customer identification information provided by each business entity, and uses this information to provide customer authentication services to the business entities.

[0045] By using such a service, business entities do not need to equip themselves with a system for performing customer authentication based on biometric information. As a result, the burden of equipment costs is reduced. Furthermore, business entities do not need to manage customer biometric information themselves. As a result, the responsibility for protecting the security of information is reduced. For example, because of these advantages, it is expected that the number of business entities that receive the services provided by the processing system 10 will increase. And the more business entities that receive the services provided by the processing system 10, the easier it will be to collect customer visit history information. In this way, the processing system 10 has a configuration that makes it easier to collect customer visit history information.

[0046] <Second embodiment> 10 shows an example of a functional block diagram of the processing system 10 of this embodiment. As shown in the figure, the processing system 10 of this embodiment differs from the processing system 10 of the first embodiment in that it includes a business entity providing unit 17.

[0047] As described in the first embodiment, the history registration unit 13 can generate, for each customer, visit history information indicating the visit history to facilities operated by each business entity (see FIG. 8). That is, the history registration unit 13 can generate, for each business entity, visit history information indicating, for each customer, the visit history to one or more facilities operated by each business entity.

[0048] The business entity providing unit 17 then provides each business entity with the visit history information for each customer generated for each business entity. As shown in FIG. 8, the visit history information is registered in association with first customer identification information for identifying the customer in the service provided by the processing system 10. Therefore, the business entity providing unit 17 may include a means for converting the first customer identification information into second customer identification information for identifying the customer in the service provided by the business entity, and providing the visit history information associated with the second customer identification information to the business entity. For example, the business entity providing unit 17 may acquire second customer identification information associated with the first customer identification information from information (see FIG. 6) that associates the first customer identification information with the second customer identification information used by the business entity to identify customers, and provide the acquired second customer identification information associated with the visit history information to the business entity.

[0049] The visit history information may be provided to the business entity via an application, a website, or the like, by email, or by other means.

[0050] The other configurations of the processing system 10 are the same as those of the first embodiment.

[0051] As described above, according to the processing system 10 of this embodiment, the same effects as those of the processing system 10 of the first embodiment are achieved.

[0052] Furthermore, the processing system 10 of this embodiment can provide each business entity with information indicating the visit history of each customer to facilities operated by that business entity. In this way, the processing system 10 of this embodiment can use the visit history information not only for the purpose of generating information to be provided, but also for the purpose of providing useful information to the business entity. Furthermore, since it is possible to provide useful information to the business entity, it is expected that the number of business entities receiving the services provided by the processing system 10 will increase. Furthermore, the more business entities receiving the services provided by the processing system 10, the easier it will be to collect customer visit history information.

[0053] <Modification> Here, we will explain variations that can be applied to the processing system 10 of the first and second embodiments. The processing system 10 may provide a payment service. For example, customers and business entities can use the payment service when making payments at a facility. The details of the web-based payment service are not particularly limited, and any technology can be used.

[0054] To improve security, the terminal device 20 may accept user input of additional information in addition to biometric information. The additional information may be a pattern, a password, or the like. The additional information is registered in advance in association with each customer. The processing system 10 may then execute a payment process for the amount received from the terminal device 20 when the authentication unit 12 successfully authenticates the customer and the additional information registered in association with the customer matches the additional information received from the terminal device 20.

[0055] Here, an example of a screen displayed on a display in this payment service is shown. Fig. 11 is a screen for inputting the payment amount. For example, a store clerk or a customer inputs the payment amount. Fig. 12 is a screen for a customer to input additional information. In this example, a pattern is input as additional information. Figs. 13 and 14 are examples of screens that are displayed after payment is completed.

[0056] In this way, by providing payment services through the processing system 10, it is expected that the number of business entities that receive the services provided by the processing system 10 will increase. As the number of business entities that receive the services provided by the processing system 10 increases, it will become easier to collect customer visit history information. Furthermore, the processing system 10 performs customer authentication based on biometric information as well as verification of additional information, thereby further improving security.

[0057] Although the present invention has been described above with reference to the embodiments (and examples), the present invention is not limited to the above-described embodiments (and examples). Various modifications that can be understood by those skilled in the art can be made to the configuration and details of the present invention within the scope of the present invention.
