  Next, the user B moves to the transmission position notified from the user A. And in the transmission position, the portable terminal 4b receives EID transmitted from the ID transmitter 3 (step S5 in FIG. 4). If this process is described in more detail with reference to FIG. 5, the user B activates the content receiving application of the portable terminal 4b and connects to the information distribution server 1, and first, the EID list is sent to the information distribution server 1. The acquisition request is transmitted (step S51). What is requested here is a list of EIDs paired with the AID notified from the user A. For example, in the example of FIG. 3, if the AID of the user A is “A001”, a list of EIDs paired with “A001” is requested. In response to this request, the information distribution server 1 returns a list of all EIDs paired with the AID “A001”, “3”, “7”,... To the portable terminal 4b (step S52). . Next, when the portable terminal 4b receives the EID transmitted from the ID transmitter 3, the portable terminal 4b collates the received EID with the EID list (step S53). If the result of this collation is a match, the browser is activated for content reception (step S54).

  Returning to FIG. 4, the mobile terminal 4 b then transmits the AID notified from the user A and the EID received at the transmission position to the information distribution server 1 to request distribution of the content, and the information distribution server as a reply 1 is received (step S6 in FIG. 4 and steps S61 and S62 in FIG. 5). Here, the information distribution server 1 searches for and acquires the content associated with the set of AID and EID received from the mobile terminal 4b from the registration information of FIG. Next, the portable terminal 4b outputs the returned content. As the output form, screen display or audio output is performed according to the type of content.

  Next, when the user B instructs the end of content output, the portable terminal 4b starts the distribution information deletion application, connects to the information distribution server 1, and transmits a registration information deletion request to the information distribution server 1 ( Step S71 in FIG. What is requested here is registration information of a set of AID and EID related to the already received content. Next, in response to the request, the information distribution server 1 deletes the registration information of the set of AID and EID related to the already distributed content from the storage means, and returns a deletion completion notification to the portable terminal 4b (FIG. 5). Step S72).

  As described above, according to the present embodiment, when the first identifier (AID) for each information distribution unit of the information sender and the second identifier (EID) associated with a specific place are prepared. Only the content is distributed. Here, the transmission position of AID and EID is notified from the information sender to a specific information receiver. As a result, it is possible to automatically distribute contents by specifying a location and a recipient.

  In FIG. 5, the information distribution server 1 deletes the registration information of the set of AID and EID related to the already distributed content in response to a request from the information receiver. After step S62), the registration information of the set of AID and EID related to the distributed content may be deleted.

  In FIG. 5, the mobile terminal 4 b of the information receiver acquires the EID list from the information distribution server 1 in advance and collates with the EID received at the transmission position. A content distribution request may be made by transmitting a set of EIDs to the information distribution server 1. In this case, the information distribution server 1 returns the corresponding content only when the combination of AID and EID received from the portable terminal 4b is registered, and returns an error when it is not registered.
