(First embodiment)

FIG. 1 is a block diagram showing the configuration of the first embodiment of the present invention, and is a functional block diagram of a content distribution system that retains the anonymity of users.

The content distribution system includes a content distribution device 10 0 provided by a carrier (communication carrier) as an intermediary, a user terminal 2 0 0 that receives content distribution, and a trader terminal 3 0 0 that provides advertisement content.

The content distribution device (server) 1 0 0 provides an interface to the user via the network. Examples of such interfaces include a scheduler application 70. The carrier provides a scheduler application as a communication service, and the user uses the scheduler. The figure shows a state in which the screen interface of the user terminal 200 is displayed.

The carrier server 100 provides an interface to the advertisement distributor through the network, and performs processing for receiving the advertisement distribution request and its contents. The advertisement distributor receives the response corresponding to the input of the request by using the vendor interface 50 provided by the carrier server. In addition, the advertisement distributor inputs specific contents such as advertisements. The advertisement distributor makes an advertisement distribution request to the carrier, and the carrier distributes the content while maintaining the anonymity of the user. In the figure, the interface provided by the server is displayed on the screen of the vendor terminal 300.

Carriers, who are intermediaries, are large companies that provide communication infrastructure. From the beginning, many personal information are strictly managed and users are highly reliable.

The user uses the scheduler application 70 provided by the reliable carrier, and registers / updates / deletes the schedule from the user terminal 20 0 to the user database 20 managed by the carrier. Carriers disassemble this schedule data and analyze it as appropriate words.

The user terminal (client) 2 0 0 may download a scheduler application as an interface provided by the server from the server, enter the schedule, and register it in the server user database. But It may be of the type that logs in to the OS on the server side as a terminal with an input function that is not implemented, and inputs the schedule using the application on the server side. In addition, a schedule may be input using a schedule application via a web browser.

When an advertisement distributor wants to use the advertisement distribution service developed by Carrier, the keyword registration interface 5 5 is used to specify keywords related to the advertisement target and advertisement contents to be distributed. Use it to register in the keyword database 30. This interface can be provided from the server 100 to the contractor's terminal, and can be registered via a web browser instead of being registered from the terminal. In addition, an application form such as paper or facsimile may be sent to the carrier as an intermediary, and the mediator may register it on the server. The carrier allocates a segment ID to this registered keyword and notifies the advertisement distributor. Next, the advertisement distributor registers the advertisement content to be distributed together with the notified segment ID using the advertisement distribution interface 58, which is one of the provider interfaces.

Server 1 0 0 searches for user information registered by the user based on the segment ID and advertising content registered by the advertising distributor, and finds the appropriate user as the advertising content distribution target and distributes the advertising content. To do. As a method of distributing advertisement content, it is possible to display it in an arbitrary area of the scheduler application 70, for example, the advertisement display area 76. In this way, information distribution that can be spam mail if it is an email is possible. Can be avoided.

FIG. 2 shows in more detail the processing performed by the carrier in the configuration diagram of the first embodiment shown in FIG. Further explanation will be given with reference to FIG. 1 and FIG. The user can perform schedule management by using the scheduler application provided by the carrier. The scheduler application manages the schedule data by passing it to the carrier. The scheduler application has an advertisement display area, and displays advertisement content in the advertisement display area each time the user uses the scheduler. In addition, while the scheduler is running, the advertisement display area updates the advertisement content displayed at arbitrary intervals. It is also conceivable. The advertisement distributor uses the keyword registration interface provided by the carrier to register the keyword related to the advertisement content, and obtains the segment ID assigned to the keyword by the registration. The keyword registration interface 55 can also be used to change keywords related to the segment ID. Furthermore, the advertisement distribution interface 58 provided by the carrier is used to request distribution of the advertisement content corresponding to the segment ID. Also, by using this advertisement distribution interface 58, the advertisement content related to the segment ID can be changed.

The carrier registers the schedule data input by the user on the server 100 in the user database 24 using the user information registration function (means) 21. Furthermore, the schedule data is converted into nouns using the phrase analysis function (means) 2 2 and registered in the user attribute database 2 3. This function not only decomposes clauses into nouns, but also acquires and registers other nouns associated with the decomposed nouns (for example, acquires nouns such as hot springs and inns from the noun Atami).

In addition, the carrier server 100 assigns segment IDs to the keywords registered by the advertisement distributor by using the segment registration function (means) 3 1 and notifies the advertisement distributor of the segment ID. Register the segment ID and keyword in the segment database 32. In addition, the server 100 accepts the advertisement content distribution request with the segment ID, but uses the keyword conversion function (means) 3 4 to obtain the keyword related to the segment ID from the segment database 3 2. The keyword search function (means) 3 6 searches the user attribute database based on the keyword to find the user who registered the corresponding information, and the content distribution function (means) 3 8 is used for those users. Deliver ad content.

In this example, the scheduler is assumed as an application to be provided to the user. However, if it is an application that can acquire detailed information about the user, such as a memorandum or a household account book, and finds benefits for the user, it is particularly The type is not limited. Next, the operation of the first embodiment will be described in more detail using the sequence diagram of FIG.

In order to request the registration of the keyword to the carrier, the advertisement distributor transmits the keyword via the key registration interface of the merchant interface 50 (401). When the server 100 receives a keyword registration request from the advertisement distributor, the segment registration function 31 assigns a segment ID to the keyword (402). The segment ID to be generated is a distinguishable identifier that is different from other segment IDs that have already been generated. The segment registration function passes the generated segment ID and the corresponding keyword to register in the segment database 32 (403). The passed segment ID and the corresponding key key are stored in the segment database (404). After registering the generated segment ID and keyword in the segment database, the segment ID is sent to the keyword registration interface used by the advertisement distributor (405). As a result, the advertisement distributor who requested the keyword registration can know the segment ID assigned to the registered key key.

On the other hand, the user uses the application provided by the carrier, presses the data save button, and transmits the data to be saved by the carrier (41 1). The carrier receives a user information registration request from the user (412). Then, it is registered in the user database (413). User information is passed from the user database 24 to the phrase analysis function 22 (414). The phrase analysis function decomposes and analyzes user information (415). This function not only decomposes clauses into nouns, but also acquires and registers other nouns associated with the decomposed nouns (for example, acquires nouns such as hot springs and inns from the noun Atami). Analyzes · Meaningful nouns obtained by analysis are passed to the user attribute database (416). The passed noun is used as user attribute information, and the user ID and user attribute information are stored in the user attribute information database (41 7).

After registering the user attribute information in 417, the last reference time of each noun of the user attribute information is verified, and maintenance such as discarding unused information is performed (418). The advertisement distributor sends it via the advertisement distribution interface to request the carrier server 100 to register the advertisement content and the keyword segment ID related thereto (4 2 0). The keyword conversion function searches the segment database 3 2 using the segment ID passed in 4 2 0 (4 2 1). As a result, the keyword corresponding to the segment ID that is the search result is obtained as the output of the keyword conversion function (4 2 2). The keyword conversion function passes the obtained keywords to the keyword search function (4 2 3). The user attribute information is searched based on the passed keyword, and for that purpose, the user attribute database 23 is accessed (4 24). Then, user attribute information corresponding to the keyword is searched (4 2 5). If the relevant information is found in the search, the user ID of the owner of the information is returned to the keyword search function (4 26). Here, the user ID is for all applicable users. The user ID obtained as a result of the keyword search function is passed to the keyword conversion function (4 27).

The user ID obtained by the keyword search function and the advertisement content passed through the advertisement distribution interface are passed to the content distribution function (4 28). The content distribution function holds the user ID and associated advertising content. When the user activates the application provided by the carrier, or when a predetermined time elapses while the application is activated, the application notifies the user ID to the content distribution function (4 30). The content distribution function 3 8 searches the corresponding advertisement content based on the user ID provided by the application (4 3 1), and delivers the corresponding advertisement content to the abrasion. The advertising content delivered from the content distribution function is displayed by the application (4 3 2). The display is performed in the advertisement display area of the application. In this example, the application displays advertisement content, but it can be replaced with content distribution using other tools (for example, a mailer).

As described above, in this embodiment, the user receives the content provided by the merchant according to the user's preference and situation without notifying the merchant of personal information (name, address, age, gender, email address, etc.). be able to. In addition, the supplier distributes content. Effective content distribution can be performed without performing the work required for communication (collecting and managing personal information of users). In addition, the carrier can collect detailed personal information of the user by allowing the user to use the abrasion provided by the carrier, and the user information is automatically collected each time the application is used. Since the information is updated, the user's personal information can be automatically maintained (discarding unused information, verifying frequently referenced information, adding new information, etc.).

(Second embodiment)

FIG. 4 is a functional block diagram of the second embodiment of the present invention. The basic configuration is almost the same as that of the first embodiment, but the keyword registration interface and the advertisement distribution interface are further devised.

In the first embodiment, the server implements a keyword registration interface that registers keywords and obtains segment IDs, and an advertisement distribution interface that distributes segment IDs and related content. provide. This assumes that a different content distribution request is made while reusing the segment ID once registered (unless the keywords related to the content are changed). In the second embodiment, an advertisement distribution interface 63 that combines a keyword registration interface is provided to an advertisement distributor. This assumes a one-time advertisement distribution request. Therefore, in the first embodiment, the advertisement distribution interface 60 designates the segment ID and the content and requests the distribution. In the second embodiment, the distribution request designates the keyword and the content. The processing performed by the user is the same as in the first embodiment. The advertisement distributor requests distribution of advertisement contents related to keywords by using the advertisement distribution interface 63 provided by the carrier. The carrier searches the user attribute database 23 using the keyword search function 36 based on the keywords passed by the advertisement distributor, finds the user who registered the relevant information, and distributes the content to that user. 3 Use 8 to distribute advertising content.

As described above, even in this embodiment, information for identifying the user and the user registered Information does not go outside the carrier, a trusted third party, and ad distributors can effectively distribute to users who have a high probability of receiving advertisements. . Also, each time the user uses the scheduler, the user attribute information is updated, so the user information is also updated automatically, and it is possible to distribute advertisements for events that occur over time. . Furthermore, as the interface provided to the advertisement distributor is combined into one, the usability for the advertisement distributor is improved, and the information and processing procedures managed by the carrier are reduced.

(Third embodiment)

FIG. 5 is a functional block diagram of the third embodiment of the present invention. In this embodiment, another method is used for the method of registering keywords by the advertisement distributor. Note that the processing performed by the user is the same as that in the embodiment, and a description thereof will be omitted. In the first and second embodiments, the carrier obtains the keyword by directly inputting the keyword to the interface provided by the carrier, but in this embodiment, the advertisement distributor Uses the advertising distribution interface 64 provided by the carrier to deliver only the content.

The carrier implements the keyword acquisition function (means) 3 7 and is a function that analyzes and acquires related keywords by analyzing the contents of the content. For example, if the content is a still image, keywords can be acquired by using existing technologies such as OCR. In this way, the advertisement distributor can acquire appropriate keywords without entering a keyword, which leads to improved usability of the interface provided to the advertisement distributor. The content can be not only still image data but also video data and audio data.

The present invention can be applied to a business model such as advertisement distribution using an NGN network. It can also be applied to Internet operations.

This application claims priority based on Japanese Patent Application No. 2 0 0 7— 0 5 5 1 0 4 filed on Mar. 6, 2007, the entire disclosure of which is hereby incorporated by reference herein. Into.
