Description

  The present invention relates to an information distribution technique for distributing information according to user attributes.

  In recent years, Internet advertisements, such as banner advertisements, are widely used. The Internet advertisement has a targeting property that the distribution content can be selected according to, for example, a user's access history to the website. Here, an access history between a plurality of websites browsed by a user can be acquired using, for example, a cookie transmitted and received.

  As a technique for improving targeting in such Internet advertisement, for example, Patent Document 1 discloses a user-limited network system that provides information distribution and services limited to a region via the Internet. In this system, the user who is the contractor is specified by using the authentication means of the contractor.

  Here, the user receives a service on a standard set-top box (STB) or a web page. At this time, user authentication is performed by inserting a personal authentication IC card into an IC card slot installed in the STB, inputting a user ID on a personal computer (PC), or personal authentication software or CD-ROM. It is implemented by starting up.

  Further, Patent Document 2 uses the IP (Internet Protocol) address of a user terminal and the regional information vs. regional database to determine the region of the user terminal, and provides web information corresponding to the determined region to the user terminal. A Web page distribution technique for transmission is disclosed.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a schematic diagram in an embodiment of an information distribution system according to the present invention.

  In the information distribution system of the embodiment shown in FIG. 1, when a user information terminal 2 acquires a web page from a web (Web) server 8 connected to the Internet (determined according to the attribute of the user). Information such as advertisements suitable for the user can be posted on the web page. Here, the information terminal 2 has a web browser application installed therein, and can render the acquired web page on a display. This web browser does not need to be equipped with a special application, plug-in, add-on, or the like.

  Specifically, this information distribution system includes a HEMS (Home Energy Management System) device 1 connected to a home network (LAN) provided in a user's living area (home), and an information terminal also connected to the home network. 2 is included. Here, a user is one household (user household) in this embodiment, and is a unit as an information distribution destination specified by an identifier held by the HEMS device 1 described later. In such a unit, the user may be an individual or a member of a household, for example.

  The HEMS device 1 is an identifier management unit, which is assigned a private IP (Internet Protocol) address (hereinafter abbreviated as a p-IP address) related to a home network, and holds a “household ID” that is a user identifier. doing. Here, the HEMS device 1 and the information terminal 2 can communicate with each other via the home network, and the HEMS device 1 obtains a “household ID” acquisition request from the information terminal 2 to the assigned p-IP address. The received “household ID” can be notified. The information terminal that has received the notification of “household ID” can know from which household (its own web browser) is trying to access.

  Further, the HEMS device 1 acquires life-related amount data relating to at least one of the user's power consumption, gas usage amount, and water usage amount, and associates this life-related amount data with the “household ID”. It is also preferable that transmission is possible. In FIG. 1, the HEMS device 1 acquires the power consumption amount data of the user (household) from the smart meter 3 as life related amount data.

  In addition, the HEMS device is a device that can grasp the usage status of power, gas, and water in the house. The utilization status grasped here can be displayed on a dedicated display terminal capable of communicating with the HEMS device. Furthermore, it is also possible to provide information distribution services such as advertisements and coupons for residents (users) using this display terminal. In this information distribution system, advertisement distribution based on the resident (user) attribute information can be performed not only on such a dedicated display terminal but also on the web browser of the information terminal 2 connected to the home network. . At this time, such advertisement distribution is possible without installing a dedicated application or logging in to the web application.

  The information terminal 2 is an information processing apparatus such as a smartphone, a tablet computer, a notebook computer or a personal computer (PC), a set top box (STB), a television (TV), and the like.

  Furthermore, the information distribution system in this embodiment includes a connection management server 5 as a connection management unit connected to the Internet, which is a wide area network, a user attribute management server 6 as a user information management unit, and an information management / distribution unit. As an advertisement management / distribution server 7. Here, the Internet and a home network (LAN) are interconnected via an access network which is, for example, a carrier communication network. This access network is, for example, a fixed network such as an optical fiber network or ADSL (Asymmetric Digital Subscriber Line), a wireless LAN such as Wi-Fi (registered trademark), WiMAX (Worldwide Interoperability for Microwave Access), LTE (Long Term Evolution). ) Or 3G (3rd Generation) or the like.

  The connection management server 5 acquires the p-IP address of the HEMS device 1 itself from the HEMS device 1, and the global IP address (related to the wide area network) acquired for the p-IP address and the HEMS device 1 (hereinafter referred to as g). -IP address and abbreviation) are stored in advance in association with each other.

  Next, when the connection management server 5 receives an acquisition request for the p-IP address of the HEMS device 1 from the information terminal 2 (which tries to acquire “household ID”), the connection management server 5 Notify the information terminal 2 of the p-IP address associated with the g-IP address. As a result, the information terminal 2 can request the “household ID” from the HEMS device 1 using the p-IP address (of the HEMS device 1) acquired from the connection management server 5 as a destination.

  The user attribute management server 6 stores the “attribute information” of the user in association with each user “household ID” in advance, and stores the “household ID” (obtained from the HEMS device 1) as information. When received via the terminal 2, the “attribute information” associated with the household ID is transmitted to the information terminal 2, for example.

  Thus, according to the present information distribution system, it is possible to distribute information suitable for the user in units of users without forcing the user to enter a special ID. Here, the user attribute management server 6 is a user information management unit, and may be a server that distributes information related to users other than “attribute information”. For example, for each “household ID” of a user, an introduction or advertisement of a product / service or information related to the user's hobbies / preferences, etc. acquired in a questionnaire or the like is stored in association with each other. Information associated with the designated “household ID” may be distributed.

  Further, the user attribute management server 6 estimates the living situation based on the life-related amount data relating to the user received from the HEMS device 1, and associates the estimated living situation with “household ID” as “attribute information”. It is also preferred to preserve. This living situation is the state of the user in the household area (home) that changes depending on the living behavior of the user who is a resident in the living area (home), such as at home, sleeping, cooking, bathing, etc. Or the behavioral situation.

  The life-related amount data that is the estimation material may be acquired from other means capable of measuring or acquiring the life-related amount. For example, living from a life-related quantity meter such as a smart meter 3 (power meter, water meter, gas meter, etc.) to the user attribute management server 6 via a dedicated communication line of a power company, water company, gas company, etc. Related quantity data may be transmitted. For example, the smart meter 3 can transmit power consumption to MDMS (Meter data Management System) (not shown), and the user attribute management server 6 can acquire the power consumption from the MDMS.

  Similarly, the advertisement management / distribution server 7 shown in FIG. 1 receives “advertisement information” as distribution information based on “attribute information” received from the user attribute management server 6 via (or without) the information terminal 2. It is determined or generated, and this “advertisement information” is delivered to the information terminal 2 in order to be output (displayed) by the information terminal 2.

  According to the information distribution system described above, the HEMS device 1 and the information terminal 2 can communicate with each other, and the user information terminal 2 can acquire the “household ID” from the HEMS device 1. Next, when the information terminal 2 specifies this “household ID” and accesses a predetermined server, information such as “advertisement information” suitable for the attribute of the user can be specified and distributed. It is. Here, the user can acquire information suitable for his / her attributes without performing a special operation such as inputting a special ID or adding a function (such as an add-on or plug-in) to the web browser. it can.

  The information terminal 2 also preferably displays the acquired “advertisement information” as, for example, a banner advertisement on the web page acquired from the web server 8. The web page acquired by the information terminal 2 includes an advertisement tag (information tag) including a script describing a processing procedure in the information terminal 2 for acquiring “advertisement information” (“attribute information”). You may have. The web browser installed in the information terminal 2 can read this script and perform the above-described processing related to advertisement distribution according to the script.

  The advertisement management / distribution server 7 is an information management / distribution unit, and may be a server that distributes information other than advertisements. For example, life advice such as energy saving, warning information, or related news may be generated and stored for each user attribute, and information associated with the designated “attribute information” may be transmitted.

  Furthermore, the configuration of the home network is not limited to the embodiment of FIG. For example, the smart meter (life related quantity meter) 3 may be directly connected to the HGW (home gateway) 4, and the smart meter (life related quantity meter) 3 and the HEMS device 1 are combined into one device. Is also possible. Moreover, the user attribute management server 6 may be installed in the living area (home).

  Further, in FIG. 1, instead of the smart meter 3, a CT sensor installed on a distribution board, a clamp meter (overhead ammeter), or an outlet tap (tap wattmeter) installed in an outlet is used. Also good. In this case, it is possible to measure the power consumption amount of each distribution in the house or the individual power consumption amount of the home appliance by using a CT sensor, an outlet tap or the like and output it to the HEMS device 1. In addition, by using these measurement values, the user attribute management server 6 can estimate a more specific life situation with higher accuracy.

  FIG. 2 is a schematic diagram in another embodiment of the information distribution system according to the present invention.

  The information distribution system of the embodiment shown in FIG. 2 also has the same configuration function unit as the system shown in FIG. 1, and when the user information terminal 2 acquires a web page from the web server 8, Information such as advertisements determined accordingly can be posted on the web page.

  However, in the information distribution system shown in FIG. 2, unlike the system shown in FIG. 1, a home network (LAN) is provided for each of a plurality of households (household A, household B, and household C in FIG. 2) in an apartment house such as an apartment. ) And HGW4 is installed in each household. All these HGWs 4 are connected to one router 9.

  The router 9 has a g-IP address 123.123.123.123 related to the Internet, and is uniquely identified by this address on the Internet. The HGWs 4 installed in the households A and B have a router function, and p-IP addresses of 192.168.0.2 and 192.168.0.3 are assigned to the WAN (Wide Area Network) side, respectively.

  Further, the HEMS devices 1 and the information terminal 2 equipped with a web browser are connected to the HGWs 4 of the households A and B. The same p-IP address 192.168.1.3 is assigned to the HEMS devices 1 of both households. On the other hand, the HGW 4 of the household C is a hub, and a HEMS device 1 and a television (TV) as the information terminal 2 are connected to the hub. Further, the p-IP address 192.168.0.5 is assigned to the HEMS device 1 of the household C.

  As described above, in the embodiment illustrated in FIG. 2, as a result of the p-IP address being assigned to the HEMS device 1 or the information terminal 2, the p-IPs of a plurality of HEMS devices 1 are associated with one g-IP address. A state where an IP address is associated has occurred. This state can also occur, for example, when a cable television is connected.

  FIG. 3 is a functional block diagram of each device constituting one embodiment of the information distribution system according to the present invention.

  According to FIG. 3, first, the HEMS device 1 has a communication interface 11 and a processor memory. Here, the processor memory realizes its function by executing a program for causing the computer mounted on the HEMS device 1 to function. In addition, the processor memory functions as an ID holding unit 12, a life related amount data management unit 13, and a life related amount data storage unit 14.

  The ID holding unit 12 holds the household ID of the household (user) where the device is installed, and obtains the household ID from the information terminal 2 to the p-IP address (assigned to the HEMS device 1) And notifies the requesting information terminal 2 of the retained household ID. In this case, the HEMS device 1 is set to behave as a server in order to respond to access from the information terminal 2 (the web browser).

  The life-related amount data management unit 13 receives, for example, life-related amount data related to at least one of the power consumption, gas usage, and water usage of the household (user) from the smart meter 3 via the communication interface 11. The acquired life related amount data is stored in the life related amount data storage unit 14 in association with the household ID of the household (user). Further, the set of the life-related amount data and the household ID acquired or stored is transmitted to the user attribute management server 6 via the communication interface 11. Note that the HEMS device originally includes the function of the life-related quantity data management unit 13, but the present information distribution system can implement a form that does not use this function, and at least the function of the ID holding unit 12 described above can be implemented. I just need it.

  In addition, as an example of data stored in the life-related amount data storage unit 14, a 24-dimensional or 48-dimensional (power consumption) feature amount from the power consumption amount in the time zone of every hour or every 30 minutes constituting the day. Vectors may be generated, and M (power consumption) feature amount vectors corresponding to each day in M days (M is a natural number) may be acquired, stored, and managed. Note that such life-related amount data may be accumulated outside the HEMS device 1, for example, in a storage in a user's living area (home), a server outside the house, or the like.

  Similarly, according to FIG. 3, the connection management server 5 includes a communication interface 51 and a processor memory. Here, the processor memory realizes its function by executing a program for causing the computer installed in the connection management server 5 to function. Further, the processor memory functions as an address data management unit 52 and an address data storage unit 53.

  The address data management unit 52 acquires a p-IP address (of the HEMS device 1) from the HEMS device 1 via the communication interface 51, and the p-IP address and the g-IP address acquired for the HEMS device 1 Are stored in the address data storage unit 53 as an address table. It is also preferable to acquire a household ID together with the p-IP address from the HEMS device 1 and store the p-IP address and the g-IP address in association with each household ID. In this case, it is possible to determine whether or not the household ID is associated with the g-IP address, and as described later, it is possible to distinguish unauthorized access using the household ID.

  When the address data management unit 52 receives a request for acquiring a p-IP address (of the HEMS device 1) from the information terminal 2, the address data management unit 52 addresses the p-IP address associated with the g-IP address of the request source. Called from the data storage unit 53 and returns the p-IP address to the information terminal 2. The p-IP address acquired by the information terminal 2 is used when the information terminal 2 later accesses the HEMS device 1 and acquires the household ID.

  Even if the address data management unit 52 holds the household ID of the HEMS device 1, the address data management unit 52 does not send back the household ID information. Assuming that the household ID is returned, access from one g-IP address may cause the household ID of the household where the HEMS device related to this g-IP address is installed to become known. This is due to security concerns such as obtaining user attribute information.

  Furthermore, when the address data management unit 52 notifies the information terminal 2 of the p-IP address associated with the g-IP address of the request source, if there are a plurality of corresponding p-IP addresses, the address data management unit 52 For each IP address, it is also preferable to notify the information terminal 2 of access priority information set based on the number of registrations, which is the number registered in the address table of the p-IP address. At this time, the registration number itself may be notified as the access priority information.

  The information terminal 2 that has received such access priority information transmits a household ID acquisition request to the p-IP address in order from the p-IP address with the higher access priority based on the access priority information. To do. Thereby, even when the information terminal 2 acquires a plurality of p-IP addresses, the information terminal 2 can efficiently access the desired HEMS device 1 (connected to the same LAN as the information terminal 2). The router 9 is usually set so that devices between different households are not connected to each other regardless of the network configuration in each household. As a result, even if a plurality of p-IP addresses are acquired, the information terminal 2 expects that the destination indicated by the p-IP address is not the HEMS device 1 in the same living area (home) as itself. Therefore, the desired p-IP address can be determined.

  FIG. 4 is a table showing an embodiment of the address table stored in the connection management server 5. According to FIG. 4, the p-IP address and the g-IP address are associated with each household ID (ID1 to ID5). Here, household ID1, household ID2, and household ID3 are households in the same apartment house, and have the same g-IP address 123.123.123.123.

  FIG. 5 is a table showing an embodiment in which the number of registrations is associated with each p-IP address. As shown in FIG. 5, for each p-IP address associated with each g-IP address, the address data management unit 52 generates a table in which the number of registrations in the address table of the p-IP address is associated. It is also preferable to do. Such a table can be generated from the information in the address table shown in FIG. In the case of the embodiment of FIG. 5, for example, when the information terminal 2 requests acquisition of the p-IP address with the g-IP address 123.123.123.123, the connection management server 5 has the registration number 2 at the p-IP address 192.168.1.3. (Or first priority) may be associated, and the registration number 1 (or second priority) may be associated with the p-IP address 192.168.1.5, and both may be transmitted to the information terminal 2.

  Returning to FIG. 3, the HEMS device 1 monitors its own p-IP address and g-IP address, and periodically, at a predetermined timing, or when these addresses change, the connection management server 5 On the other hand, it is also preferable to update the p-IP address and the g-IP address corresponding to the household ID of the HEMS device 1 in the address table held by the server. In general, the p-IP address and the g-IP address vary. For this reason, the HEMS device 1 needs to update these addresses. In the connection management server 5, the p-IP address and the g-IP address of the HEMS device 1 to be updated can be identified by the household ID notified from the HEMS device 1.

  Further, the HEMS device 1 may check its own p-IP address every hour, for example, as a monitoring method of its own address, and detect the change. Further, it is possible to check its own g-IP address by accessing an external server having a g-IP address reply function and detect the change. Such a g-IP address confirmation process for an external server may be executed by the connection management server 5.

  Furthermore, when the connection management server 5 that has been requested for the above update process or has confirmed that it is necessary to update the g-IP address itself, updates the g-IP address corresponding to the household ID of the target HEMS device 1. It is also preferable to update the same g-IP address corresponding to a household ID different from the household ID. This is because when the g-IP address of one household (user) changes, the g-IP address also changes in other households using the same g-IP address.

  For example, in the embodiment shown in FIG. 2, when it is detected that the g-IP address of the HEMS device 1 of the household A (ID 1) has changed from 123.123.123.123 to 123.123.123.111, the connection management server 5 The g-IP address 123.123.123.123 stored in association with ID1 which is the household ID of the user is updated to 123.123.123.111. At this time, the household B (ID2) and household C (ID3) that have the same g-IP address as that before the update are also updated to 123.123.123.111.

  Returning to FIG. 3, the user attribute management server 6 includes a communication interface 61 and a processor memory. Here, the processor memory realizes its function by executing a program for causing the computer installed in the user attribute management server 6 to function. Further, the processor memory functions as a user attribute estimation unit 62, an estimated data management unit 63, and an attribute information storage unit 64.

  For example, the user attribute estimation unit 62 receives the life-related amount data and the household ID of the HEMS device 1 from the HEMS device 1 via the communication interface 61, and the life-related amount data related to the household ID (user). Estimate living conditions based on Next, the estimated living situation is stored in the attribute information storage unit 64 in association with the household ID of the user as user attribute (household attribute) information related to the user.

  Here, it is also preferable that the user attribute estimation unit 62 estimates a living situation for a living situation item (for example, getting up, going out, returning home, going to bed, etc.) to be estimated based on the power consumption data of the user. For example, the presence (home) / absence estimation by simple threshold determination for power consumption, and the clustering method, random forest method and logistic regression analysis method for the (power consumption) feature vector obtained from the HEMS device 1 Various known methods such as application to estimate living conditions can be applied. The feature quantity vector may be generated by the user attribute estimation unit 62 using the power consumption data acquired from the HEMS device 1.

  As a more specific estimation method of the living situation in the user attribute estimation unit 62, for example, when estimating the wake-up time or time zone, the power consumption amount in the morning time zone is the same as the nighttime (standby) power amount of the day. In comparison, when it becomes larger with a difference greater than or equal to a predetermined threshold, it can be assumed that “wake-up” occurs at the time of the increase or the unit time zone (30 minutes). That is, it can be estimated that, for example, “wake up from 6:00 to 6:30” as a living situation. For example, when estimating a bedtime or a time zone, the power consumption amount is a difference value within a predetermined threshold value compared with a representative value of the (standby) power amount at night in the past in the night time zone. It can be assumed that “sleeping” has occurred at the time or the unit time zone (30 minute zone) at the time when the time has decreased. That is, it can be estimated that the living situation is “sleeping at 22:45”, for example.

  Note that the user attributes (household attributes) that can be estimated are not only static attributes such as the above-mentioned wake-up time and bedtime, but also real-time dynamics such that the user (resident) is currently active in the house. User attributes. Further, the estimation process as described above can be performed using the gas usage data and / or the gas usage data instead of or together with the power consumption data.

  Furthermore, it is also possible to estimate the living situation based on the operation (power consumption) situation of the HEMS compatible equipment under the HEMS equipment 1. In addition, attributes such as occupancy status in the home, for example, 21:00 to 23:00 may be estimated based on the output from the home sensor. Furthermore, user attribute information can be collected from the answer results of questionnaires conducted on users (residents) without being estimated or combined with user attributes, and stored in the attribute information storage unit 64. It is.

  When the estimated data management unit 63 receives the household ID (obtained from the HEMS device 1) via the information terminal 2, the estimated data management unit 63 transmits the user attribute information as the living situation associated with the household ID via the communication interface 61. To send.

  FIG. 6 is a table showing an example of user attribute information stored in the attribute information storage unit 64.

  In the user attribute information shown in FIG. 6, for each estimation target household (ID1 to ID3), an attribute value is associated with each of the two attribute items (“family composition” and “frequency of going out on holidays”). For example, in household ID 1, the household attribute (living condition) is estimated as “Family composition” as “Having children” and “Frequently going out on holidays” as “High” (for example, 60% or more).

  Returning to FIG. 3, the advertisement management / distribution server 7 includes a communication interface 71 and a processor memory. Here, the processor memory realizes its function by executing a program for causing the computer installed in the advertisement management / distribution server 7 to function. Further, the processor memory functions as an advertisement generation / determination unit 72, an advertisement data management unit 73, and an advertisement data storage unit 74.

  The advertisement generation / determination unit 72 determines or generates distribution advertisement information based on the attribute information received from the user attribute management server 6 via the information terminal 2 or not. Here, for each attribute information that can be received, it is also preferable to generate a distribution advertisement table in which the distribution advertisement information to be distributed to the information terminal 2 is stored in association with each other and store the distribution advertisement table in the advertisement data storage unit 74. In this case, the advertisement generation / determination unit 72 selects the distribution advertisement information associated with the attribute information transmitted from the user attribute management server from the distribution advertisement table.

  FIG. 7 is a table showing an embodiment of the distribution advertisement table stored in the advertisement data storage unit 74.

  In the distribution advertisement table shown in FIG. 7, for each distribution rule ID (AD1 to AD3) for identifying a distribution rule, the condition that the user attribute should satisfy and the distribution advertisement information that should be distributed when this condition is satisfied correspond to each other. It is remembered. In the present embodiment, the content of the distribution advertisement information is determined by determining the distribution ratio of a plurality of advertisements related to specific products / services. For example, as rule AD1, information terminal 2 of a household having a household attribute (living status) of “with children” as “family composition” and “high frequency of holidays” (for example, 60% or more) On the other hand, it is determined that the advertisement of “travel tour for children” is 70% and the remaining 30% of “toys that can be played with family outdoors” are distributed advertisements. Here, the distribution ratio can be, for example, the ratio of the time for displaying the distribution advertisement, the ratio of the display area, or the ratio of the number of displays.

  Returning to FIG. 3, the advertisement generation / determination unit 72 distributes the determined or generated distribution information to the information terminal 2 via the communication interface 71 so that the information terminal 2 outputs (displays) the distribution information. The distributed advertisement can be, for example, advertisement content such as text, an image, and a moving image. The advertisement generation / determination unit 72 further receives communication history information on the Internet (wide area network) from the information terminal 2 and determines or generates distribution information based on the communication history information and the received user attribute information. Is also preferable.

  Similarly, according to FIG. 3, the web server 8 includes a communication interface 81 and a processor memory. Here, the processor memory realizes its function by executing a program for causing the computer mounted on the web server 8 to function. Further, the processor memory functions as a web page management unit 82 and a web page storage unit 83.

  In response to the web page acquisition request from the information terminal 2, the web page management unit 82 transmits the web page stored in the web page storage unit 83 to the information terminal 2 as a response via the communication interface 81. This web page includes an advertisement placement page, and an HTML (HyperText Markup Language) file of this page describes a series of processing procedures executed in order to acquire distribution advertisement information in the information terminal 2 such as JavaScript (registered trademark). The advertisement tag which is the code described in is embedded. The web browser installed in the information terminal 2 can read the advertisement tag and execute the above-described processing related to advertisement distribution according to the script code.

  FIG. 8 is a sequence diagram showing an embodiment of the information distribution method according to the present invention. Of the processing steps shown below, steps S101 to S114 correspond to preliminary processing, and steps S121 to S133 correspond to distribution processing.

(S101) The HEMS device 1 transmits the life-related amount data to the user attribute management server 6 in association with the household ID held by itself.
(S102) The user attribute management server 6 estimates and stores the user attribute for the user associated with the linked household ID based on the acquired life-related amount data.

(S111, S112) The HEMS device 1 acquires or confirms its own p-IP address in the home network. Further, the connection management server 5 is notified of the p-IP address information and the household ID held by itself. In the example of FIG. 2, for example, the HEMS device 1 of the household A transmits ID1 that is the household ID and the p-IP address 192.168.1.3.
(S113, S114) The connection management server 5 acquires the g-IP address of the HEMS device 1 that is the transmission source of the received p-IP address information. Further, for each household ID, the g-IP address and p-IP address acquired for the HEMS device 1 are stored in association with each other. In the example of FIG. 2, for example, for household A, information “ID1, 123.123.123.123, 192.168.1.3” is stored.

(S121) The information terminal 2 transmits a web page acquisition request to the web server 8.
(S122) The web server 8 transmits the web page in which the advertisement tag is embedded to the information terminal 2.
(S123) The information terminal 2 displays the acquired web page, reads the advertisement tag, and proceeds to the advertisement distribution process. Thereafter, the web browser installed in the information terminal 2 performs processing related to advertisement distribution according to the script described in the advertisement tag.

(S124) The information terminal 2 transmits a p-IP address acquisition request to the connection management server 5 in order to acquire the p-IP address of the HEMS device 1.
(S125) The connection management server 5 acquires the g-IP address of the request source, and returns a p-IP address stored in association with the g-IP address to the information terminal 2.

  Here, as an example, when the information terminal 2 of the household A in FIG. 2 accesses the connection management server 5 and the connection management server 5 holds the address table in FIG. 4, the connection management server 5 Get 123.123.123.123 as the g-IP address of. Next, two p-IP addresses 192.168.1.3 and 192.168.0.5 associated with 123.123.123.123 are returned to the information terminal 2 as g-IP addresses.

  In step S125, the connection management server 5 preferably returns the number of registrations in the address table of the p-IP address together with the p-IP address. In the example of household A in FIG. 2 described above, the connection management server 5 returns information “192.168.1.3, 2 (number of registrations)” and “192.168.0.5, 1 (number of registrations)”.

(S126) The information terminal 2 transmits a household ID acquisition request to the acquired p-IP address of the HEMS device 1 in order to acquire the household ID of the HEMS device 1.

  Here, as an example, the information terminal 2 of the household A in FIG. 2 acquires two p-IP addresses 192.168.1.3 and 192.168.0.5, but the p-IP address of the HEMS device 1 in the same house is 192.168. 1.3 and access to 192.168.0.5 fails. As a result, in step S126, the information terminal 2 is connected only to the p-IP address 192.168.1.3, and can communicate with the desired HEMS device 1.

(S127) The HEMS device 1 returns the stored household ID to the information terminal 2. In the embodiment relating to household A in FIG. 2, ID1 which is the household ID is returned.

  In step S126, it is also preferable to use the registered number of p-IP addresses notified from the connection management server 5 as the priority of the p-IP addresses that the information terminal 2 tries to access. This is because it is more likely that the HEMS device 1 can be accessed earlier if the access is preferentially performed from a p-IP address with a large number of registrations. In the embodiment of the information terminal 2 of household A in FIG. 2, when information “192.168.1.3, 2 (number of registrations)” and “192.168.0.5, 1 (number of registrations)” is acquired from the connection management server 5, the information The terminal 2 tries to access with priority from “192.168.1.3”.

(S128) The information terminal 2 transmits a user attribute acquisition request specifying the household ID to the user attribute management server 6 in order to acquire the user attribute of the user related to the acquired household ID.
(S129) The user attribute management server 6 returns the user attribute information associated with the designated household ID to the information terminal 2.

  In the embodiment according to household A in FIG. 2, the household ID ID1 is transmitted to the user attribute management server 6 in step S128. When the user attribute management server 6 holds the user attribute information shown in FIG. 6, in step S129, “family structure: multiple family members, children, holiday outing frequency associated with the user attribute information ID1” in step S129. : ”Is returned” to the information terminal 2.

(S130) The information terminal 2 transmits an advertisement distribution request designating the user attribute to the advertisement management / distribution server 7 in order to acquire a distribution advertisement corresponding to the acquired user attribute.
(S131, S132) The advertisement management / distribution server 7 determines or generates a distribution advertisement based on the received user attribute, and transmits distribution advertisement information, which is content such as an advertisement image or advertisement video, to the information terminal 2. To do.
(S133) The information terminal 2 displays the acquired delivery advertisement as, for example, a banner advertisement on the acquired web page.

  In the embodiment related to household A in FIG. 2, in step S130, user attribute information “family structure: multiple family members and children, frequent going out on holidays: high” is transmitted to the advertisement management / distribution server 7. . If the advertisement management / distribution server 7 holds the distribution advertisement table shown in FIG. 7, in step S132, the rule AD1 is applied and “travel tour advertisement for children” is set at a rate of 70%. The remaining 30% of “toys for toys that can be played with family outdoors” will be distributed.

  Here, as a change mode according to steps S131 and S132, the advertisement management / distribution server 7 sends a distribution advertisement based on not only the user attribute but also the action history (communication history) on the web of the user (information terminal 2). It is also preferable to determine or generate and transmit to the information terminal 2. In this case, the action history (communication history) on the web can be acquired using a cookie received from the information terminal 2.

  For example, when it is estimated that the user (household) attribute is “household with children” and “browsing history of the examination examination information site” is acquired, in rule AD1 of FIG. Instead of the advertisement of “travel tour” and the advertisement of “toys that can be played with family outdoors”, or in combination with these at a predetermined ratio, the advertisement of “learning school” may be determined or generated. In this way, by adopting a behavioral targeting advertisement method that uses a behavior history on the web, it is possible to further enhance the advertising effect.

  FIG. 9 is a sequence diagram showing another embodiment of the information distribution method according to the present invention.

  In the embodiment shown in FIG. 9, a user attribute management unit 6 'and an advertisement management / distribution unit 7' are provided. Both functional units may be installed as independent servers, or may be different functional components in one server. The processing functions in the user attribute management unit 6 'and the advertisement management / distribution unit 7' are the same as the processing functions in the user attribute management server 6 and the advertisement management / distribution server 7 shown in FIG. Moreover, in this embodiment, the process similar to embodiment of FIG. 8 is implemented until the step (S126 and S127) when the information terminal 2 accesses the HEMS apparatus 1 and acquires household ID. Therefore, in the following description, steps after access to the HEMS device 1 by the information terminal 2 are shown.

(S201) The information terminal 2 transmits a user attribute acquisition request specifying the household ID to the advertisement management / distribution unit 7 ′ in order to acquire the user attribute of the user related to the acquired household ID.
(S202) The advertisement management / distribution unit 7 ′ transmits or outputs the received household ID to the user attribute management unit 6 ′.

(S203) The user attribute management unit 6 ′ transmits or outputs user attribute information associated with the received household ID to the advertisement management / distribution unit 7 ′.
(S204, S205) The advertisement management / distribution unit 7 ′ determines or generates a distribution advertisement based on the received or input user attribute, and returns the distribution advertisement information to the information terminal 2.
(S206) The information terminal 2 displays the acquired delivery advertisement as, for example, a banner advertisement on the acquired web page.

  In the embodiment described above, the number of communications between the information terminal 2 (the web browser) and the server can be reduced in the advertisement distribution process. When the user attribute management unit 6 ′ and the advertisement management / distribution unit 7 ′ are installed as independent servers, the respective communication interfaces are set so that communication processing can be executed between these servers. .

  FIG. 10 is a sequence diagram showing still another embodiment of the information distribution method according to the present invention.

  In the embodiment shown in FIG. 10, it is possible to prevent unauthorized acquisition of user attributes due to unauthorized use of household IDs. Here, the steps up to the step (S126 and S127) in which the information terminal 2 accesses the HEMS device 1 to acquire the household ID includes the step in which the connection management server 5 generates an address table, and is the same as the embodiment in FIG. Processing is performed. Therefore, in the following description, steps after access to the HEMS device 1 by the information terminal 2 are shown.

(S301) The information terminal 2 transmits a user attribute acquisition request specifying the household ID to the user attribute management server 6 in order to acquire the user attribute of the user related to the acquired household ID.
(S302) In order to confirm that the received household ID is legitimately acquired by the information terminal 2, the user attribute management server 6 acquires the g-IP address of the access source, and uses this g-IP address. And sent to the connection management server 5 together with the received household ID.

Here, the connection management server 5 stores the household ID acquired from the HEMS device 1, the p-IP address, and the g-IP address acquired for the HEMS device 1 in association with each other in advance as an address table. Yes.
(S303) The connection management server 5 determines whether or not the g-IP address and household ID received from the user attribute management server 6 are associated in the held address table.

(S304) When it is determined in step S303 that the association is true, the connection management server 5 assumes that the household ID has been legitimately acquired by the information terminal 2, and the true determination result. Is transmitted to the user attribute management server 6.
(S305 to S309) Hereinafter, steps S305 to S309 in this embodiment are the same as steps S129 to S133 in the embodiment shown in FIG. Here, assuming that the household ID has been obtained properly, finally, an advertisement corresponding to the user attribute is distributed and presented to the user.

(S311) On the other hand, when it is determined in step S303 that the g-IP address is not associated with the household ID, the connection management server 5 instructs that the advertisement distribution based on the user attribute is not performed. Is transmitted to the information terminal 2. As a result, the information terminal 2 cannot acquire user attributes.
(S312) The information terminal 2 that has received the instruction not to carry out the advertisement distribution based on the user attribute displays a normal advertisement that does not depend on the user attribute (for example, embedded in the web page from the beginning).

  As a change mode, the connection management server 5 may transmit an instruction to the advertisement management / distribution server 7 to the effect that the advertisement distribution based on the user attribute is not performed in step S311. In this case, for example, the advertisement management / distribution server 7 determines or generates a distribution advertisement (not depending on the user attribute) based on the communication history information (by the cookie) acquired from the information terminal 2 and transmits it to the information terminal 2. be able to.

  As described above, according to the embodiment of FIG. 10, the user attribute information is obtained only when it is determined that the household ID is properly acquired (only when the user attribute management unit receives a true determination result). Is output from the user attribute management unit and used. Thereby, for example, it is possible to prevent the occurrence of a situation in which a person who has illegally acquired a household ID accesses the user's attributes (such as living conditions) without accessing from the corresponding user's home. it can. That is, it becomes possible to prevent unauthorized acquisition of user attributes due to unauthorized use of household IDs.

  FIG. 11 is a sequence diagram showing still another embodiment of the information distribution method according to the present invention.

  The embodiment shown in FIG. 11 is a modification of the embodiment shown in FIG. 9, and it is possible to prevent unauthorized acquisition of user attributes due to unauthorized use of household IDs. Here, step S401 and steps S406 to S409 in FIG. 11 are the same processing as step S201 and steps S203 to S206 in FIG. 9, respectively. Therefore, in the following description, steps different from the embodiment of FIG. 9 in the present embodiment are shown.

(S402) The advertisement distribution / management unit 7 ′ transmits or outputs the household ID included in the advertisement distribution request received from the information terminal 2 to the user attribute management unit 6 ′ together with the g-IP address of the request source.
(S403) The user attribute management unit 6 ′ that has received or entered the household ID from the advertisement distribution / management unit 7 ′ in step S402 confirms that this household ID has been legitimately acquired by the information terminal 2. The acquired g-IP address is transmitted to the connection management server 5 together with the received household ID.

Here, the connection management server 5 stores the household ID acquired from the HEMS device 1, the p-IP address, and the g-IP address acquired for the HEMS device 1 in association with each other in advance as an address table. Yes.
(S404) The connection management server 5 determines whether or not the g-IP address and household ID received from the user attribute management unit 6 ′ are associated with each other in the held address table.

(S405) When it is determined in step S404 that the association is true, the connection management server 5 assumes that the household ID has been legitimately acquired by the information terminal 2, and the true determination result. Is transmitted to the user attribute management unit 6 ′.
(S406 to S409) The steps are the same as steps S203 to S206 in the embodiment shown in FIG. Here, assuming that the household ID has been obtained properly, finally, an advertisement corresponding to the user attribute is distributed and presented to the user.

(S411) On the other hand, when it is determined in step S404 that the g-IP address is not associated with the household ID, the connection management server 5 instructs that the advertisement distribution based on the user attribute is not performed. Is transmitted to the information terminal 2. As a result, the information terminal 2 cannot acquire user attributes.
(S412) The information terminal 2 that has received the instruction not to carry out advertisement distribution based on the user attribute displays a normal advertisement that does not depend on the user attribute (for example, embedded in the web page from the beginning).

  As a change mode, in step S411, the connection management server 5 may transmit an instruction to the effect that the advertisement distribution based on the user attribute is not performed to the advertisement management / distribution unit 7 '. In this case, for example, the advertisement management / distribution unit 7 ′ determines or generates a distribution advertisement (not depending on the user attribute) based on the communication history information (by the cookie) acquired from the information terminal 2 and transmits it to the information terminal 2 can do.

  As described above, even in the embodiment of FIG. 11 in which the number of steps between the terminal and the server is suppressed, only when it is determined that the household ID has been acquired properly (the user attribute management unit displays a true determination result). Only when it is received), user attribute information is output from the user attribute management unit and used. This makes it possible to prevent unauthorized acquisition of user attributes due to unauthorized use of household IDs.

Here, the case where normal information is displayed on the information terminal 2 without distributing the advertisement information using the user attribute information is summarized.
(1) If the g-IP address of the HEMS device is not registered in the connection management server 5, it is determined that the HEMS device is not installed and a normal advertisement is displayed. This determination can be made, for example, in steps S124 and S125 of FIG.
(2) Although the g-IP address of the HEMS device is registered in the connection management server 5, if the information terminal 2 fails in communication connection with the p-IP address acquired from the connection management server 5 as the destination, the HEMS It is determined that the device is not installed or is installed in a network where the HEMS device cannot communicate directly, and a normal advertisement is displayed. This determination can be made, for example, in the steps S126 and S127 of FIG.
(3) In the embodiment shown in FIGS. 10 and 11, a normal advertisement is displayed at the stage where it is determined that the household ID is illegally used (step S303 in FIG. 10 and step S404 in FIG. 11).

  As described above in detail, according to the information distribution system and method of the present invention, the user terminal acquires the user identifier from the identifier management unit in the same LAN, and the user information management unit is based on this identifier. Information related to the user is transmitted. As a result, information suitable for the user can be distributed in units of users. Further, even when a user's action history on the web cannot be used, for example, advertisement distribution based on user attributes is possible. Furthermore, when an action history on the web can be used, advertisement distribution based on the user attribute is also performed together with this action history, and the advertisement effect can be further enhanced.

  Further, according to the information distribution system and method of the present invention, information suitable for the user can be distributed for each user without forcing the user to bear a special input. For example, a user who is a viewer of a web page displayed on a web browser of a terminal does not need to perform a special operation such as inputting a personal authentication ID, adding a function such as an add-on to a web browser, or a plug-in. This makes it possible to distribute information suitable for the user in units of users.

  Of course, the information relating to the distributed user is not limited to the advertisement information. For example, the user's life status information (under the user's permission) and appropriate support information (eg, saving advice and household management advice) on the user's use of power, gas and / or water can be distributed. Moreover, it becomes possible to realize marketing more suited to the needs of the user (household) by using this information.

  For the various embodiments of the present invention described above, various changes, modifications, and omissions in the technical idea and scope of the present invention can be easily made by those skilled in the art. The above description is merely an example, and is not intended to be restrictive. The invention is limited only as defined in the following claims and the equivalents thereto.
