  The advertisement distribution program for the web page 3a of the mobile phone 4 creates a URL with the actual advertisement HTML based on the identification information of the transmitted advertisement (S11, T12), and the advertisement is based on the created URL. Advertisement information (HTML) is acquired from the server 5, and the advertisement information is displayed on the Web page 3a (S12, T13, T14).

  Therefore, according to the present embodiment, since the target advertisement is determined based on the attribute information related to the user identification information and the local storage identification information, a more efficient target advertisement can be provided.

  Next, the operation of the advertisement distribution system when accessing the Web page 2a (without attribute information) of the domain A will be described with reference to the flowchart of FIG. 4 and the timing chart of FIG.

  The user accesses the Web page 2a (without attribute information) of the domain A from the mobile phone 4 (S21, T21). An advertisement distribution program (Java script) is embedded in the Web page 2 a of the domain A, and the advertisement distribution program of the Web page 2 a is executed (activated) on the Web browser program 33 of the mobile phone 4. (S22).

  Next, the advertisement distribution program of the Web page 2a transmits an advertisement distribution request to the processing server 21 (S23, T22).

  When receiving the advertisement distribution request, the target advertisement distribution program 22 of the processing server 21 acquires attribute information from the local storage 34 of the mobile phone 4 (S24, T23), and stores the acquired attribute information of the local storage 34 in the database server 23. Transmit (advertisement ID acquisition request: T24).

  The database server 23 determines the identification information of the advertisement to be distributed based on the attribute information of the local storage 34 (decryption if encrypted) (S25, T25), and the determined identification information of the advertisement Is returned to the processing server 21 (S26, T26). The processing server 21 transmits the advertisement identification information to the mobile phone 4 (S27, T27).

  The advertisement distribution program for the Web page 2a of the mobile phone 4 creates a URL with the actual advertisement HTML based on the transmitted advertisement identification information (S28, T28), and the advertisement is based on the created URL. Advertisement information (HTML) is acquired from the server 5, and the advertisement information is displayed on the Web page 2a (S29, T29, T30).

  Therefore, according to the present embodiment, it is possible to provide an effective target advertisement by using the attribute information of the local storage even when accessing a page of a domain where attribute information does not exist.

  In the above-described embodiment, the flow of processing has been described separately when accessing a page of a domain where attribute information exists and when accessing a page of a domain where attribute information exists. By providing means for determining the presence or absence, the processing may be shared.

  That is, the terminal determines whether or not the first attribute information related to the identification information of the user of the terminal exists in the server related to the web page of the predetermined domain accessed, and the first attribute information exists Then, when it is determined, the advertisement distribution request is transmitted to the advertisement distribution server together with the first attribute information, and when it is determined that the first attribute information does not exist, only the advertisement distribution request is transmitted to the advertisement distribution server. .

  When the server for advertisement distribution receives only the first attribute information and the advertisement distribution request transmitted from the terminal or the advertisement distribution request transmitted from the terminal, the second attribute information stored in the local storage of the terminal When the first attribute information and the advertisement distribution request are received from the terminal, the identification information of the advertisement is determined based on the received first attribute information and the acquired second attribute information. When only the advertisement distribution request is received, the advertisement identification information is determined based on the acquired second attribute information, and the determined advertisement identification information is transmitted to the terminal.

<Other embodiments>
In the above-described embodiment, when a program executed on the mobile phone 4 accesses the Web page 3a, attribute information related to the user identification information is sent to the processing server 21 together with the advertisement distribution request, and the target of the processing server 21 The case where the advertisement distribution program 22 acquires attribute information from the local storage 34 of the mobile phone 4 has been described.

  In the present embodiment, the latest attribute information of a plurality of Web pages can be stored in the local storage 34 of the mobile phone 4 sent to the processing server 21, and a targeting advertisement is performed based on the latest attribute information. is there.

  In this embodiment, data stored in the local storage is stored in an encrypted state in a key-value store (hereinafter referred to as “KVS”) format. Note that the above-described embodiment does not prevent data from being stored in the KVS storage format.

  Here, the KVS format refers to a method in which a corresponding unique indicator (key) is set for arbitrary data (value) to be stored, and these are stored in pairs. In the present embodiment, KVS data (value) is encrypted.

  In KVS, a character string or a numerical value (called a key) for distinguishing from other data is assigned to data to be stored, and the data and set are stored in a storage device or the like. When data is read, the corresponding data can be taken out by designating a preset key.

  First, the operation of the mobile phone 4 will be described with reference to the flowchart of FIG.

  The user accesses the Web page 2a of domain A (without attribute information) or the Web page 3a of domain B (with attribute information) from the mobile phone 4 (S31). An advertisement delivery program (Java script) is embedded in the domain A web page 2a or the domain B web page 3a. It is executed (activated) on the computer 33 (S32).

  Next, the advertisement distribution program determines whether or not the attribute information is stored in the local storage 34 of the mobile phone 4 (S33).

  If it is determined in S33 that it is stored in the local storage 34, attribute information is added to the advertisement distribution request (S34).

  In S33, when it is determined that the attribute information is not stored in the local storage 34 of the mobile phone 4, or after adding the local storage 34 to the advertisement distribution request in S4, from the server of the Web page accessed by the mobile phone 4 It is determined whether or not the attribute information (hereinafter referred to as “media attribute information” in order to distinguish it from the attribute information stored in the local storage 34) can be acquired (S35).

  Specifically, when the mobile phone 4 accesses the Web page 2a of the domain A, since the server group 2 of the domain A does not have attribute information, it is determined that it does not have media attribute information, and the domain B Web When the page 3a is accessed, the server group 3 in the domain B has attribute information, so it is determined that it has media attribute information.

  If it is determined in S35 that the media attribute information can be acquired, the media attribute information is acquired from the server, and the acquired media attribute information is associated with the URL of the Web page and stored in the local storage 34 of the mobile phone 4 ( S36).

  Next, the acquired media attribute information is added to the advertisement distribution request (S37), and the process proceeds to S38.

  If it is determined in S35 that the media attribute information cannot be acquired from the Web page server, or after adding the acquired media attribute information to the advertisement distribution request in S7, the advertisement distribution request is transmitted to the processing server 21 (S38).

  Thereafter, the mobile phone 4 determines whether or not a response (attribute information + advertisement identification information) to the advertisement distribution request has been received (S39). If it is determined in S39 that a response has been received, the received attribute information is stored in the local storage 34 (S40).

  The advertisement distribution program of the mobile phone 4 creates a URL with the actual advertisement HTML based on the transmitted advertisement identification information (S41). Based on the created URL, the advertisement information ( HTML) is acquired and advertisement information is displayed on the Web page (S42).

  FIG. 7 is a diagram illustrating an advertisement distribution request transmitted to the processing server 21.

  In FIG. 7A, FIG. 7A is transmitted when it is determined in S33 that the attribute information is not stored in the local storage 34, and it is determined in S35 that the media attribute information cannot be obtained from the accessed Web page server. The advertisement delivery request to be performed is shown. That is, when the attribute information cannot be acquired from the local storage 34 and the accessed web page server, only the advertisement distribution request is transmitted.

  (B) is an advertisement distribution request transmitted when it is determined in S33 that the attribute information is stored in the local storage 34, and it is determined in S35 that the media attribute information cannot be acquired from the accessed web page server. Is shown.

  (C) is an advertisement distribution request transmitted when it is determined that the attribute information is not stored in the local storage 34 in S33 and it is determined that the media attribute information can be acquired from the accessed web page server in S35. Is shown.

  (D) is an advertisement distribution request transmitted when it is determined in S33 that the attribute information is stored in the local storage 34 and it is determined in S35 that the media attribute information can be acquired from the accessed web page server. Is shown.

  FIG. 8 is a diagram showing the local storage 34 of the mobile phone 4.

  As shown in the figure, media attribute information 41 and attribute information 42 are stored in the local storage 34.

  As described in S35, the media attribute information 41 is attribute information acquired from the server of the Web page accessed by the mobile phone 4, and is stored in association with the URL of the accessed Web page. If it cannot be obtained, the media attribute information is not saved. In the figure, as an example, an ID, sex, date of birth, address, and the like associated with a URL (https) are shown.

  As described later, the attribute information 42 stores attribute information obtained by performing data merging processing of attribute information and media attribute information in the database server 23. In the figure, as an example, a mail address, a telephone number, a date of birth, an address and the like associated with the ID are shown. The attribute information data is stored in an encrypted state in the KVS format.

  In addition, the data stored in the KVS format of the media attribute information 41 may be decrypted on the server side when used so as to be encrypted.

  Next, the operation of the server group 3 will be described with reference to the flowchart of FIG.

  When the processing server 21 receives the advertisement distribution request from the mobile phone 4 (S51), the processing server 21 delivers the advertisement distribution request to the database server 23. The database server 23 determines whether or not encrypted attribute information is added to the advertisement distribution request (S52).

  If it is determined in S52 that the encrypted attribute information is not added to the advertisement distribution request, the attribute information basic data is assumed to be “empty” (S53), and the process proceeds to S55. If it is determined that the attribute information has been added, the attribute information is decoded, the decoded attribute information is set as “attribute information basic data” (S54), and the process proceeds to S55.

  In S55, the database server 23 determines whether or not media attribute information is added to the advertisement distribution request (S55).

  In S55, when it is determined that the media attribute information is added to the advertisement distribution request, the media attribute information is merged with the basic attribute information (S56), and the process proceeds to S57. If it is determined in S55 that the media attribute information is not added to the advertisement distribution request, the process proceeds to S57.

  FIG. 10 is a diagram for explaining the attribute information merging process in S56.

  This figure shows a case where the decoded attribute information method basic data 51 and the media attribute information 52 are merged to generate new attribute information 53.

  In the figure, "attribute information basic data" has "Gender" as a key and "male" as data. Similarly, "Birth = 1980-05 -04", "Tel = 090-5449-* *** "," Address = yokohama "," Hobby = tennis "," Pet = cat "," Interest = economy, newspaper ", and" Game A level = 5 ".

  "Media attribute information" is "Gender = male", "Birth = 2980-05-04", "Hobby = dance", "Pet = dog", "Interest = economy, newspaper", "Game B level = 87" , “Game C level = 41”.

  In the data merge process, when a key that does not exist in the attribute information basic data 51 exists in the media attribute information 52, the key and its data are added. If the same key as the key of the attribute information basic data 51 exists in the media attribute information 52, the data of the key is rewritten to the data of the media attribute information. In this embodiment, the case where the data of the media attribute information 52 is prioritized will be described. However, the data of the attribute information basic data 51 may be prioritized. Also, new data may be prioritized by referring to the data creation time.

  When data merging is performed according to such a rule, the new attribute information 53 is “Gender = male”, “Birth = 1980-05-04”, “Tel = 090-5449-****”, “Address = yokohama ”,“ Hobby = dance ”,“ Pet = dog ”,“ Interest = economy, newspaper ”,“ Game A level = 5 ”,“ Game B level = 87 ”,“ Game C level = 41 ”.

  Next, the database server 23 determines advertisement identification information based on the attribute information (S57), the attribute information data is encrypted (S58), and the determined advertisement identification information and data are encrypted. The attribute information thus delivered is delivered to the processing server 21.

  Note that the encrypted attribute information may be stored in the database server 23 after the attribute information data merged in S56 is encrypted in S58. Thereby, the server management company can obtain customer information including a lot of customer local data.

The processing server 21 transmits the identification information of the advertisement delivered from the database server 23 and the attribute information obtained by encrypting the data to the browser 33 of the mobile phone 4 as a response (S59).
Therefore, according to another embodiment of the present invention, user attribute information can be collected from a plurality of servers, and target advertisements are selected using the collected user attribute information. An advertisement can be displayed.

  Further, since the collected identification information from the plurality of servers can be stored only in the local storage 34 of the mobile phone 4 without being stored in the server, the number of servers can be reduced.

  Furthermore, since the attribute information is updated every time the Web page is accessed, the latest attribute information can always be maintained.

  Further, even when a web page that does not have attribute information is accessed, the target advertisement is displayed using the attribute information stored in the local storage 34 of the mobile phone 4. Can be displayed.

  Furthermore, by setting the storage URL to https, it can also be used for advertisement distribution on a secure site.

  In the above-described embodiment, the processing of the processing server 21 and the database server 23 has been described separately. However, these may be performed by one server.
