Description

  The present invention relates to an advertisement distribution system and an advertisement distribution method based on a browsing history on a terminal side. In particular, the present invention relates to an advertisement distribution system and an advertisement distribution method for distributing advertisements without transmitting the browsing history on the terminal side to the outside.

  When a terminal is connected to the Internet and a so-called Web page is browsed, an advertisement may be displayed together with the displayed Web page. This advertisement is not only used for promotion, but generally has a purpose of setting a so-called link and guiding it to the advertiser's homepage by clicking to contribute to the purchase of goods.

  If the advertisement is not viewed by a user who is interested in the field in which the advertisement is advertised, the advertisement is not effective and is wasted. Thus, in order to effectively advertise, what kind of advertisement is displayed on which web page is important.

  Conventionally, based on the genre and theme of the content of the displayed web page, the site targeting (content targeting) that determines the type of advertisement to be displayed, and the profile such as personal information of the user collected in advance are displayed. A method for determining an advertisement to be performed is known.

  However, since site targeting depends on the type of content, it does not always meet the needs of advertisers. Moreover, even if it is the system which refers to a user's profile, the profile does not necessarily represent the user's current interests, interests or situations. For example, when a profile is registered, even if a certain user is interested in purchasing a car or a house, the user does not always have an interest and interest after purchasing. In such a case, if the profile is not updated, an irrelevant advertisement is displayed, which may be useless.

  Therefore, a method has been proposed in which location information included in a user's terminal is acquired and advertisement information limited to the communication means or transmission area of the terminal is provided (see, for example, Patent Document 1).

  In the invention described in Patent Document 1, the area information is acquired based on the telephone number of the communication means of the terminal. Certainly, the telephone number transmitted from the terminal often indicates the current location of the user and can be said to be highly credible information. However, accurate information about the interests and interests that the user currently has cannot be obtained by only the position information.

  There has been proposed a method called behavioral targeting that determines an advertisement to be displayed using a behavioral history on the web such as a browsing record of a web page on a user terminal. This is because when the terminal accesses the server, the server acquires the browsing history of the accessed terminal together with the request for the Web page. The acquired browsing history, words included in the requested Web page, and the like are matched with advertisements that are candidates for display (for example, see Patent Document 2).

  However, in any of the above methods, the server side needs to acquire the user's profile and browsing history. In general, a profile is registered in advance in a specific site, along with basic personal information such as name and address, and a field of interest and interest, and stored in a server. The browsing history is also included in the browsing request transmitted from the terminal and used on the server side. The browsing history indicates the current user's preference, interest, and the like, and constitutes a kind of personal information. On the Internet, it is said that the possibility of personal information leaking cannot be completely prevented, and there are users who hesitate about sending such personal information to the outside. Also, if personal information is leaked, there is a high risk of misuse and the possibility of unexpected disadvantages to the user cannot be denied.
