[Figure 6] 10 is a flowchart illustrating an example of a processing flow in an information processing device. DETAILED DESCRIPTION OF THE INVENTION

[0020] [Overview of information processing device 1] 1 is a diagram showing an overview of an information processing device 1. The information processing device 1 is a computer that outputs advertising information to a user terminal 2, such as a smartphone or personal computer, used by a user.

[0021] Information processing device 1 is communicably connected to user terminal 2 and storage device 3 via a communication network such as the Internet or a mobile phone line. Storage device 3 stores health information for each of multiple users and purchasing behavior information indicating their purchasing behavior. Storage device 3 may consist of a single device, or may consist of one or more devices that store health information and one or more devices that store purchasing behavior information.

[0022] The information processing device 1 acquires a user ID from the user terminal 2 as user identification information for identifying the user who uses the user terminal 2 ((1) in FIG. 1). The information processing device 1 refers to the health information and purchasing behavior information stored in the storage device 3, and acquires the user's health information and purchasing behavior information associated with the acquired user ID ((2) and (3) in FIG. 1).

[0023] The information processing device 1 identifies advertising information to be presented to the user based on the acquired health information and purchasing behavior information ((4) in FIG. 1). The advertising information is, for example, advertising information for products corresponding to the health indicated by the user's health information or stores that sell such products, and is advertising information corresponding to stores that are predicted to be highly likely to be purchased by the user based on the user's purchasing behavior information. The information processing device 1 outputs the identified advertising information to the user terminal 2 ((5) in FIG. 1) and displays the advertising information on the user terminal 2. In this way, the information processing device 1 can present effective advertising to the user.

[0024] [Functional configuration of information processing device 1] Next, a detailed description will be given of the configuration of the information processing device 1. Fig. 2 is a diagram showing the functional configuration of the information processing device 1. The information processing device 1 has a communication unit 11, a storage unit 12, and a control unit 13.

[0025] The communication unit 11 is a communication interface for transmitting and receiving data to and from external devices such as the user terminal 2 and the storage device 3 via a communication network such as the Internet or a mobile phone line. The storage unit 12 is a storage medium that stores various types of data, and includes a ROM (Read Only Memory), a RAM (Random Access Memory), a hard disk, etc. The storage unit 12 stores a program executed by the control unit 13. The storage unit 12 stores a program that causes the control unit 13 to function as an acquisition unit 131, an identification unit 132, and an output unit 133.

[0026] The storage unit 12 also stores advertising management information that associates advertising information, a store ID serving as store identification information for identifying a store corresponding to the advertising information, and a type of product corresponding to the advertising information. Fig. 3 is a diagram showing an example of the advertising management information. As shown in Fig. 3, the advertising management information associates the advertising ID for identifying the advertising information, the advertising information, the store ID indicating the store corresponding to the advertising information, and the type of product corresponding to the advertising information.

[0027] The advertising information is, for example, video information, image information, or text information showing an advertisement for a product or store. The advertising information may include bonus information showing a bonus that will be given to a user in response to the purchase of the advertised product or the purchase of a product at the advertised store. One piece of advertising information may be associated with multiple product types. Furthermore, one piece of advertising information may be associated with the store IDs of multiple stores that sell the product indicated by the advertising information.

[0028] The control unit 13 is, for example, a CPU (Central Processing Unit). The control unit 13 executes a program stored in the storage unit 12, thereby functioning as an acquisition unit 131, an identification unit 132, and an output unit 133.

[0029] The acquisition unit 131 acquires a user ID for identifying a user, and acquires health information associated with the acquired user ID, including the contents of the user's diet and information related to the user's health, and purchasing behavior information indicating the user's purchasing behavior.

[0030] First, the acquisition unit 131 acquires a user ID from the user terminal 2. For example, applications that are associated with the user's user ID, provide various services, and are capable of displaying advertisement information are installed in the user terminal 2. The applications include, for example, a health app that is an application for managing the user's diet and health, and a payment app that is an application for making various payments such as code payments using the user terminal 2. The acquisition unit 131 acquires the user ID from the user terminal 2 on which these applications are running.

[0031] When acquiring a user ID from a user terminal 2, acquiring unit 131 acquires health information and purchasing behavior information associated with the user ID from storage device 3. Here, a brief description of storage device 3 will be given. Storage device 3 acquires user IDs and health information from health apps installed on user terminals 2 used by multiple users, and stores them in its own storage unit.

[0032] Fig. 4 is a diagram showing an example of health information. As shown in Fig. 4, the health information is associated with a user ID. The health information is information that associates at least a date, a diet history indicating the contents of the user's meals, and health-related information that is information related to the user's health. The health-related information includes, for example, information related to exercise such as the user's step count and exercise history, and information indicating the user's health condition such as blood pressure, weight, and obesity level.

[0033] The storage device 3 also acquires user IDs and purchasing behavior information from payment apps installed on the user terminals 2 used by each of the multiple users, and stores the user IDs and purchasing behavior information in its own storage unit. FIG. 5 is a diagram showing an example of purchasing behavior information. As shown in FIG. 5, the purchasing behavior information is associated with the user ID. The purchasing behavior information is, for example, information that associates at least the date on which the user purchased a product, a store ID for identifying the store where the user purchased the product, purchased product information indicating the purchased product by the user, and the purchase price of the purchased product.

[0034] The acquisition unit 131 sends an acquisition request to the storage device 3, which includes the user ID acquired from the user terminal 2 and requests the acquisition of health information and purchasing behavior information, and acquires the health information and purchasing behavior information associated with the user ID from the storage device 3.

[0035] The identification unit 132 identifies advertising information to be presented to the user based on the health information and purchasing behavior information acquired by the acquisition unit 131. Specifically, first, the identification unit 132 identifies the type of product corresponding to the advertising information to be presented to the user based on the health information acquired by the acquisition unit 131.

[0036] For example, the determination unit 132 calculates the calorie intake of the user for a predetermined period from the diet history included in the health information acquired by the acquisition unit 131, and calculates the calorie consumption of the user for a predetermined period based on the exercise information included in the health-related information. Furthermore, the determination unit 132 determines the obesity level of the user based on, for example, information indicating the health condition included in the health-related information.

[0037] The identification unit 132 identifies the type of product corresponding to the advertising information to be presented to the user based on the calculated relationship between the calorie intake, calorie expenditure, and obesity level for a predetermined period. For example, type determination information associating the range of calorie gain or loss obtained by subtracting the calorie expenditure from the calorie intake for a predetermined period, the obesity level, and the type of product is stored in the storage unit 12. The identification unit 132 calculates the calorie gain or loss corresponding to the user by subtracting the calorie expenditure from the calculated calorie intake for the predetermined period. The identification unit 132 then refers to the type determination information to identify the type of product corresponding to the calculated calorie gain or loss and the obesity level. Note that the identification unit 132 identified the type of product based on the obesity level, but is not limited thereto. The identification unit 132 may also identify the type of product based on other information indicating the health condition, such as blood pressure.

[0038] Next, the identification unit 132 identifies advertising information to be presented to the user from among a plurality of pieces of advertising information corresponding to the identified type of product, based on the purchasing behavior information acquired by the acquisition unit 131. For example, the identification unit 132 identifies a store where the user purchased a product, based on the purchasing behavior information acquired by the acquisition unit 131, and identifies, from the plurality of pieces of advertising information, advertising information associated with the identified type of product and a store ID indicating the identified store, as advertising information to be presented to the user.

[0039] Here, multiple stores from which the user has purchased products may be identified based on the purchasing behavior information. In this case, the identification unit 132 may identify, from the multiple stores from which the user has purchased products, a store where the purchase amount of products corresponding to the identified product type or the number of purchases of products corresponding to the product type is relatively high, based on the purchasing behavior information. Then, the identification unit 132 may identify, from the multiple pieces of advertising information, advertising information associated with the identified product type and a store ID indicating the identified store, as advertising information to be presented to the user.

[0040] Note that the identification unit 132 identifies, among the plurality of pieces of advertising information, advertising information associated with the store ID of the store where the user purchased the product as advertising information to be presented to the user, but this is not limiting. For example, the identification unit 132 may identify advertising information associated with the type of store where the user purchased the product as advertising information to be presented to the user.

[0041] In this case, the storage unit 12 stores the advertisement ID, the advertisement information, the type of product corresponding to the advertisement information, and the type of store corresponding to the advertisement information in association with each other as advertisement management information. The store type is, for example, information indicating the sales format of the store. The sales format of the store includes, for example, at least direct sales in which products are sold in a physical store and mail order sales in which products are sold in a virtual store accessible via a communication network.

[0042] The identification unit 132 identifies the type of store where the user purchased the product based on the purchasing behavior information acquired by the acquisition unit 131. For example, store information in which a store ID, a store type, and a store location are associated with each other is stored in the storage unit 12. The identification unit 132 identifies the store ID of the store where the user purchased the product based on the purchasing behavior information acquired by the acquisition unit 131, and identifies the type of store associated with the identified store ID by referring to the store information.

[0043] Here, the identification unit 132 may identify both direct sales and mail order as store types. In this case, the identification unit 132 may identify the type of store with the highest purchase amount of products corresponding to each identified store type or the highest frequency of product purchases, based on the purchasing behavior information.

[0044] The identification unit 132 refers to the advertisement management information and identifies advertisement information associated with the identified product type and store type as advertisement information to be presented to the user. In this way, the information processing device 1 can provide the user with an advertisement corresponding to a store that the user is likely to use to purchase products of the identified product type, thereby further improving the advertising effectiveness.

[0045] The output unit 133 outputs the advertising information identified by the identification unit 132 to the user terminal 2 used by the user. The output unit 133 transmits the advertising information identified by the identification unit 132 to the user terminal 2 from which the user ID acquired by the acquisition unit 131 was acquired, and causes the advertising information to be displayed on the user terminal 2. The user terminal 2 displays the advertising information received from the information processing device 1, for example, on the screen of the application that transmitted the user ID.

[0046] When the output unit 133 outputs advertising information corresponding to a store that uses direct sales as a sales format to the user terminal 2, the output unit 133 may be configured to output information indicating the amount of exercise required for a user to purchase a product at the store corresponding to the advertising information.

[0047] In this case, the identification unit 132 determines whether the sales format of the store corresponding to the advertising information is direct sales. If the identification unit 132 determines that the sales format is direct sales, it acquires terminal location information indicating the location of the user terminal 2 and identifies the location of the store corresponding to the advertising information. The identification unit 132 identifies the amount of exercise required for the user to purchase a product at the store based on the location indicated by the identified terminal location information and the identified location of the store. For example, the identification unit 132 identifies the amount of exercise required for the user to purchase a product at the store, corresponding to each of multiple means of transportation that the user can take. Then, the output unit 133 outputs the advertising information identified by the identification unit 132 and the identified amount of exercise to the user terminal 2. In this way, the information processing device 1 can make the user recognize that purchasing a product at the store corresponding to the advertising information will lead to exercise.

[0048] Note that there are cases where the same advertisement information is identified by the identification unit 132 at multiple different times, and the advertisement information is output to the user terminal 2 by the output unit 133. In this case, the user may not be interested in advertisements with the same content, which may result in a problem that the effectiveness of the advertisement is not improved. In response to this, the identification unit 132 may change the content of the advertisement indicated by the advertisement information based on the health condition of the user.

[0049] In this case, acquisition unit 131 acquires first health information, which is health information of the user at a first timing, and second health information, which is health information at a second timing prior to the first timing. The first timing is, for example, the timing when acquisition unit 131 acquires a user ID from user terminal 2, and the second timing is the timing when output unit 133 previously output advertising information to user terminal 2.

[0050] For example, the storage unit 12 associates the user ID of the user, the advertising ID of advertising information sent to the user terminal 2 of the user, and the date on which the advertising information was sent, and stores the associated information as advertising history information. The acquisition unit 131 refers to the advertising history information and determines whether the user has viewed the same advertising information in the past based on whether the advertising ID of advertising information identified by the identification unit 132 based on the first health information and the purchasing behavior information is included. If the acquisition unit 131 determines that the user has viewed the same advertising information in the past, it identifies the date on which the advertising information was sent, which is associated with the advertising ID. Then, the acquisition unit 131 identifies the health information corresponding to the identified date as the second health information.

[0051] Identification unit 132 identifies a change in the user's health condition based on the information indicating the user's health condition included in the first health information and the information indicating the user's health condition included in the second health information acquired by acquisition unit 131. For example, identification unit 132 determines whether the health condition has worsened by identifying a change in the user's obesity level, blood pressure, etc.

[0052] Then, the identification unit 132 changes the content of the advertisement indicated by the advertising information presented to the user based on the identified change in the health condition. For example, the identification unit 132 cancels the advertisement indicated by the advertising information presented to the user, changes the applicable period of the advertisement, or changes the discount rate of the product indicated by the advertisement based on the identified change in the health condition. Specifically, when the identification unit 132 determines that the user's health condition has deteriorated, it cancels the advertisement indicated by the advertising information presented to the user, shortens the applicable period of the advertisement, or reduces the discount rate of the product indicated by the advertisement. In this case, it is assumed that the advertisement management information associates the change in the advertisement with the change in the user's health condition.

[0053] The specification unit 132 may be configured to transmit condition information indicating conditions for changing the advertisement information in accordance with changes in the health condition to the user terminal 2 in advance. In this way, the information processing device 1 can make the user aware that the advertisement content will be changed to content that is unfavorable to the user when it is determined that the user's health condition has worsened, and can encourage the user not to let their health condition worsen.

[0054] Furthermore, when it is determined that the user's health condition has deteriorated, the identification unit 132 may extend the application period of the advertisement indicated by the advertising information presented to the user or increase the discount rate of the product indicated by the advertisement. In this way, when it is determined that the user's health condition has deteriorated, it is possible to increase the probability that the user will view the advertisement content that is improved compared to before the deterioration and purchase the product corresponding to the advertising information in an attempt to improve their health condition.

[0055] Furthermore, for example, when the product corresponding to the advertisement information is a health product related to the user's health condition, the identification unit 132 notifies the user terminal 2 of information indicating that the user's health condition has worsened, and also notifies the user terminal 2 of information indicating that the content of the advertisement for the health product has improved in response to the worsening of the health condition compared to the content of the advertisement before the health condition worsened. For example, the identification unit 132 notifies the user terminal 2 of a message such as "For those of you whose blood pressure has increased compared to last week, we have extended the special offer period for Tokuho Black Oolong Tea!" together with the advertisement information, or notifies the user terminal 2 of the message by including it in the advertisement information. This allows the user to recognize that their health condition has worsened and consider purchasing a product in an attempt to improve their health condition, thereby increasing the probability that the user will purchase the product.

[0056] Furthermore, when determining that the user's health condition has not deteriorated (has been maintained or improved), the identification unit 132 may extend the application period of the advertisement indicated by the advertising information presented to the user or increase the discount rate of the product indicated by the advertisement. For example, when the product corresponding to the advertising information is a health product related to the health condition, the identification unit 132 notifies the user terminal 2 of information indicating that the user's health condition has improved, and also notifies the user terminal 2 of information indicating that the content of the advertisement for the health product has improved in response to the improvement in the health condition compared to the content of the advertisement before the improvement in the health condition.

[0057] In this case, on the condition that the user has previously purchased the health product corresponding to the advertisement information and that the user's health condition has not deteriorated, the identification unit 132 may notify the user terminal 2 of information indicating that the content of the advertisement for the health product has improved compared to the content of the previous advertisement. For example, the identification unit 132 may notify the user terminal 2 of a message such as "Your body fat percentage has decreased compared to last week. To further reduce your body fat percentage, we've extended the discount period for salads!" together with the advertisement information, or may notify the user terminal 2 of the message by including it in the advertisement information. This allows the user to recognize that their health condition has improved or is being maintained, and to consider purchasing a product in an attempt to further improve or maintain the health condition, thereby increasing the probability that the user will continue to purchase products.

[0058] [Operation flow] Next, a description will be given of the flow of processing in the information processing device 1. Fig. 6 is a flowchart showing an example of the flow of processing in the information processing device 1. First, the acquisition unit 131 acquires a user ID from the user terminal 2 (S1). Next, the acquisition unit 131 refers to the storage device 3 and acquires health information and purchasing behavior information associated with the acquired user ID (S2).

[0059] Next, the identification unit 132 identifies the type of product of the advertising information to be output to the user terminal 2 based on the acquired health information (S3). Next, the identification unit 132 identifies the store where the user purchased a product of the identified product type based on the acquired purchasing behavior information (S4).

[0060] Next, the identification unit 132 refers to the advertisement management information and identifies advertisement information corresponding to the identified product type and the purchase store (S5). Next, the output unit 133 outputs the advertisement information identified in S5 to the user terminal 2 that is the sender of the user ID (S6).

[0061] [Variation 1] In the above-described embodiment, the identification unit 132 identifies the advertising information to be output to the user terminal 2 used by a user based on the user's health information and purchasing behavior information, but this is not limiting. For example, the identification unit 132 may identify the advertising information to be output to the user terminal 2 based on the health information and purchasing behavior information of multiple users.

[0062] In this case, the multiple users include, for example, a first user and a second user who has a predetermined relationship with the first user. The first user is a user who is expected to use a product corresponding to the advertising information, and the second user is a user to whom the advertising information is distributed. The predetermined relationship may be, for example, that the first user and the second user are family members or that the first user and the second user live together. For example, the storage unit 12 stores the user ID of the first user and the user ID of the second user in association with each other.

[0063] First, when the acquisition unit 131 acquires the user ID of the first user from the user terminal 2 of the first user, the acquisition unit 131 refers to the storage unit 12 and identifies the user ID of the second user associated with the user ID of the first user. The acquisition unit 131 may acquire the user ID of the second user from the user terminal 2 of the second user. Then, the acquisition unit 131 may refer to the storage unit 12 and identify the user ID of the first user associated with the user ID of the second user.

[0064] Next, the acquisition unit 131 acquires the health information of the first user associated with the user ID of the first user and the purchasing behavior information of the second user associated with the user ID of the second user. Here, the acquisition unit 131 may acquire the health information of the first user associated with the user ID of the first user, the health information of the second user associated with the user ID of the second user, and the purchasing behavior information of the second user associated with the user ID of the second user.

[0065] The identification unit 132 identifies advertising information to be presented to the second user based on the health information of the first user and the purchasing behavior information of the second user acquired by the acquisition unit 131. When the acquisition unit 131 acquires the health information of the first user and the health information and purchasing behavior information of the second user, the identification unit 132 may identify advertising information to be presented to the second user based on the health information of the first user and the health information and purchasing behavior information of the second user. Then, the output unit 133 outputs the advertising information identified by the identification unit 132 to the user terminal 2 used by the second user.

[0066] By doing this, for example, the information processing device 1 can present advertising information corresponding to the health condition of a first user to a second user who has a predetermined relationship with the first user and is highly likely to purchase a product that the first user needs on behalf of the first user.

[0067] Furthermore, the acquisition unit 131 may acquire purchasing behavior information of each of a plurality of users, including the first user, associated with the user ID of the first user. Then, the identification unit 132 may determine a second user to whom advertising information is to be presented, based on the purchasing behavior information of the plurality of users. For example, the identification unit 132 may determine, based on the purchasing behavior information of the plurality of users, a user who purchases products relatively frequently as the second user to whom advertising information is to be presented. Then, the identification unit 132 may identify advertising information to be presented to the second user, based on the health information of the first user acquired by the acquisition unit 131 and the purchasing behavior information of the determined second user.

[0068] By doing this, the information processing device 1 can present advertising information corresponding to the health condition of the first user to a second user who has a predetermined relationship with the first user and who has a relatively high probability of purchasing a product corresponding to the first user on behalf of the first user, thereby increasing the probability that a product corresponding to the advertising information will be purchased.

[0069] [Variation 2] Furthermore, although the identification unit 132 identified predetermined advertising information as the advertising information to be output to the user terminal 2, advertising information generated by a generative model may also be identified as the advertising information to be output to the user terminal 2. In this case, the control unit 13 functions as a reception unit and receives advertising setting conditions from a provider of advertising information. The advertising setting conditions include, for example, target information specifying users to whom the advertisement will be delivered, and content setting information for specifying the advertising content. The target information indicates, for example, the health status and purchasing behavior corresponding to the users to whom the advertisement will be delivered. The content setting information includes the store or product to be advertised and the content of the benefit to be included in the advertisement. The generative model is a model that outputs advertising information corresponding to the advertising setting conditions and the user's health information and purchasing behavior information, in response to input of these information.

[0070] For example, advertising setting conditions are labeled to advertising information that has been registered in advance as an output target to the user terminal 2. Then, the control unit 13 functions as a learning unit, and generates training data for training a generative model based on the advertising information, the advertising setting conditions, and health information and purchasing behavior information of the user of the user terminal 2 to which the advertising information has been output. For example, the control unit 13 generates training data using a set of the advertising setting conditions labeled to the advertising information and the health information and purchasing behavior information of the user of the user terminal 2 to which the advertising information has been output as input data for the generative model and the advertising information as output data. The control unit 13 trains the generative model based on the generated training data.

[0071] The identification unit 132 identifies an advertisement setting condition corresponding to the advertisement information to be presented to the user, based on the health information and purchasing behavior information acquired by the acquisition unit 131. For example, the identification unit 132 identifies one or more advertisement setting conditions including target information corresponding to the health condition indicated by the health information acquired by the acquisition unit 131 and the purchasing behavior indicated by the purchasing behavior information acquired by the acquisition unit 131, as the advertisement setting condition corresponding to the advertisement information to be presented to the user.

[0072] The specifying unit 132 then inputs the health information and purchasing behavior information acquired by the acquiring unit 131 and the specified advertisement setting conditions to a generation model that has been trained in advance using training data, and specifies the advertisement information generated by the generation model as the advertisement information to be presented to users. In this way, the advertiser does not need to generate advertisement information in advance, and can deliver the advertisement information to target users by specifying the advertisement setting conditions, thereby reducing the effort required for advertisement delivery.

[0073] [Variation 3] In the above embodiment, the storage device 3 stores the health information and purchasing behavior information, and the acquisition unit 131 acquires the health information and purchasing behavior information from the storage device 3. However, this is not limiting. The storage unit 12 may store the health information and purchasing behavior information, and the acquisition unit 131 may acquire the health information and purchasing behavior information from the storage unit 12.

[0074] [Effects of information processing device 1] As described above, the information processing device 1 according to the present embodiment acquires a user ID for identifying a user, acquires health information including information about the user's diet and the user's health, and purchasing behavior information indicating the user's purchasing behavior, which are associated with the acquired user ID, identifies advertising information to be presented to the user based on the acquired health information and purchasing behavior information, and outputs the advertising information to the user terminal 2 used by the user. In this way, the information processing device 1 can present effective advertisements to the user.

[0075] Furthermore, this invention will make it possible to contribute to Goal 9 of the United Nations' Sustainable Development Goals (SDGs), which is "Build resilient infrastructure, promote inclusive and sustainable industrialization, and promote innovation and resilience."
