Contents 24 related to desired objects (products, services, etc.) are selected from among. The exhibitor terminal device 6 requests the content 24 related to the object selected by the user from the information providing server 1 . In response to this request, the information providing server 1 reads out the content 24 associated with the identification information (first target ID) of the target selected by the user from the storage device 2, and sends it to the user terminal device 5 that made the request. offer. Alternatively, when a transfer destination e-mail address is specified by the user terminal device 5, the information providing server 1 transfers the content 24 read from the storage device 2 to this specified e-mail address.

FIG. 5 is a flowchart for explaining an example of processing in the system shown in FIG. An example of processing for providing the exhibitor terminal device 6 with information (second target ID) related to is shown.

The exhibitor terminal device 6 accesses the organizer server 3 and performs processing for applying as an exhibitor to an event such as an exhibition (ST100). The organizer server 3 generates exhibitor information (FIG. 3B) including the exhibitor registration information (exhibitor name, etc.) input from the exhibitor terminal device 6 and the exhibitor ID in the application process, and stores the exhibitor information in the storage device 4. register in the exhibitor DB 42 (ST105).

The user terminal device 5 also accesses the host server 3 and performs application processing for visiting an event such as an exhibition (ST110). The organizer server 3 generates user information including the personal information (name, e-mail address, etc.) input from the user terminal device 5 and the first user ID in this application process, and uses the storage device 4. Register in the person DB 41 (ST115). At least part of the user information registered in the user DB 41 may be information of users invited based on a list of arbitrary personal information.

The host server 3 accesses the information providing server 1 and requests the information providing server 1 for the optical code C1 to be printed on the admission pass 71 (ST120). At this time, the organizer server 3 provides the information providing server 1 with a first user ID that identifies the user as an anonymous individual. When the information providing server 1 acquires one or more first user IDs from the organizer server 3 (ST125), the information providing server 1, based on the acquired first user IDs, includes the first user IDs as well as the user terminal device. 5, a second user ID, which is readable information, is generated (ST130). That is, the information providing server 1 generates information about the optical code C1 (information for forming the optical code C1) as the second user ID. At this time, the information providing server 1 uses the second user ID (related to the optical code C1) so as to include information (URL, etc.) about the address on the communication network 9 for the user terminal device 5 to access the information providing server 1. information).

The information providing server 1 provides the generated second user ID (information on the optical code C1) to the organizer server 3 (ST135). The organizer server 3 acquires the second user ID (information on the optical code C1) provided by the information providing server 1 (ST140). When acquiring a plurality of first user IDs in step ST125, the information providing server 1 generates a second user ID for each of the acquired first user IDs and provides it to the organizer server 3 (ST130, ST135).

In this way, in the information providing server 1, based on the first user ID associated with the personal information in the organizer server 3, the second usage information including the first user ID and readable by the user terminal device 5 is provided. A party ID (optical code C1) is generated and provided to the host server 3 . The organizer, who is the owner of personal information, can determine the correct first user ID of each user based on the personal information of each user. The ID can also be determined, and the user terminal device 5 of each user can be made to read the correct second user ID (optical code C1). That is, the second user ID (optical code C1) provided to the organizer who is the owner of the personal information can be read by the user terminal device 5 of the correct user. As a result, the information providing server 1 can correctly determine the user operating the user terminal device 5 based on the first user ID included in the second user ID read by the user terminal device 5. becomes possible. Therefore, it is possible to collect and provide correct information on the user's action history while avoiding handling of personal information.

Exhibitor terminal device 6 accesses information providing server 1 and requests registration of products and services to be exhibited at an event such as an exhibition (ST145). Upon receiving this request, the information providing server 1 generates a new first target ID that is not registered in the action target DB 22 of the storage device 2, and also generates information (exhibitor registration information) to be included in the action target information (FIG. 2B). , object name, etc.) from the exhibitor terminal device 6 . The information providing server 1 then generates new action target information (FIG. 2B) including these pieces of information, and registers it in the action target DB 22 (ST150). As a result, the generated first target ID is stored in the storage device 2 as a registered first target ID.

The exhibitor terminal device 6 accesses the information providing server 1 and requests registration of the content 24 related to the products and services to be exhibited (ST155). Upon receiving this request, the information providing server 1 associates the first target ID related to the content 24 requested to be registered with the content 24 acquired from the exhibitor terminal device 6 and stores them in the storage device 2 (ST160). That is, the information providing server 1 generates content information (FIG. 2C) for the content 24 requested to be registered, registers it in the content DB 23, and stores the content 24 in the content storage location designated by the content information. The information providing server 1 arbitrarily generates, for example, content IDs and content storage locations in the content information (FIG. 2C), and inputs content names from the exhibitor terminal device 6 .

When the content 24 is stored in the storage device 2 in response to a request from the exhibitor terminal device 6, the information providing server 1 includes and uses the first target ID based on the first target ID related to the stored content 24. A second target ID, which is information readable by the user terminal device 5, is generated (ST165). That is, the information providing server 1 generates information about the optical code C2 (information for forming the optical code C2) as the second target ID. The information providing server 1 provides the generated second target ID (information on the optical code C2) to the exhibitor terminal device 6 (ST170). The exhibitor terminal device 6 acquires the second target ID (information on the optical code C2) provided by the information providing server 1 (ST175).

In this way, in the information providing server 1, when the content 24 is stored in the storage device 2 in response to a request from the exhibitor terminal device 6, the content 24 is included in the first target ID and is read by the user terminal device 5. 2 object IDs are generated. As a result, compared to the case where the second target IDs are generated for all the targets (products, services, etc.) registered in the action target information (FIG. 2B) of the action target DB 22, the processing load can be reduced and the storage The storage area of the device 2 can be saved.

FIG. 6 is a flowchart for explaining an example of processing in the system shown in FIG. Here is an example of the process of providing content to a .

The user terminal device 5 accesses the information providing server 1 based on this address information (ST205). The information providing server 1 that has received this access acquires the first user ID included in the optical code C1 (second user ID) read by the user terminal device 5 (ST210).

In addition, the user terminal device 5 reads the optical code C2 (second target ID) posted along with the products and services at the exhibition booth (ST215), and reads the read optical code C2 (second target ID) as information. Send to the providing server 1 . Upon receiving the optical code C2 (second target ID) from the user terminal device 5, the information providing server 1 receives the first target ID included in this second target ID and the optical code C2 (second target ID) in the user terminal device 5. (ST225).

The information providing server 1 creates a first action history including the action information acquired in step ST225 and the first user ID of the user related to the acquired action information (the first user ID acquired in step ST210). Information (FIG. 2A) is generated and registered in the action history DB 21 of the storage device 2 (ST230).

The user terminal device 5 accesses the information providing server 1 and requests display of the user's action history (ST235). Upon receiving this request, the information providing server 1 searches the action history DB 21 for the first action history information about the requesting user, and generates a screen containing the first action history information found by the search (ST240). The user terminal device 5 displays the action history screen generated by the information providing server 1 (ST245).

On the action history screen, the history of reading the optical code C2 (second target ID) is displayed, and each of the targets (products, services, etc.) that has been read has an obtainable content 24. being prepared. Therefore, the user inputs an instruction to select a product or service from which the content 24 is desired to be acquired on the action history screen. The user terminal device 5 requests the content 24 related to the product or service selected by the user from the information providing server 1 (ST250).

Upon receiving a request for content 24 related to one target (product, service, etc.), the information providing server 1 reads the content 24 associated with the first target ID of the one target from the storage device 2 . That is, the information providing server 1 reads from the storage device 2 the content 24 stored in the content storage location registered in the content information (FIG. 2C) including the first target ID of the one target. The information providing server 1 provides the content 24 read from the storage device 2 to the user terminal device 5 (ST255). The user terminal device 5 acquires the content 24 provided by the information providing server 1 (ST260).

FIG. 7 is a flowchart for explaining an example of processing in the system shown in FIG. 1, and shows an example of processing for generating second action history information by combining action history with personal information.

After the end of an event such as an exhibition, the exhibitor terminal device 6 requests the host server 3 for second action history information, which is a combination of action history and personal information (ST300). The host server 3 that receives this request reads the user information (FIG. 3A) of the user who came to the event from the user DB 41 of the storage device 4 (ST305). For example, the organizer server 3 acquires part or all of the personal information and the first user ID in the user information of the visiting user. The organizer server 3 provides the information providing server 1 with the first user IDs and personal information (part or all) of one or more users who have visited the event (ST310). The information providing server 1 acquires the first user IDs and personal information of one or more users provided by the organizer server 3 (ST315).

The information providing server 1 reads one or more pieces of first action history information (FIG. 2A) containing the first user IDs of the one or more users acquired in step ST315 from the action history DB 21 of the storage device 2 (ST320). ).

The information providing server 1 combines the first action history information and personal information of one or more users acquired from the host server 3 in step ST315, and the one or more first action history information read out from the action history DB 21 of the storage device 4 in step ST320. Based on the action history information, one or more pieces of second action history information including personal information and action information of one user are generated (ST325). The second action history information is, for example, a combination of the first action history information shown in FIG. 2A and part or all of the personal information of the user information shown in FIG. 3A.

The information providing server 1 provides the organizer server 3 with the generated one or more pieces of second action history information (ST330). The organizer server 3 acquires one or more pieces of second action history information provided by the information providing server 1, and provides this to the exhibitor terminal device 6 (ST335, ST340). Exhibitor terminal device 6 acquires one or more pieces of second action history information provided from organizer server 3 (ST345).

In this way, when the information providing server 1 generates the second action history information containing personal information, the personal information provided by the host server 3 is always used. It is never saved. Therefore, it is possible to generate the second action history information including the personal information while avoiding storing the personal information.

Further, according to the processing shown in FIG. 7, the personal information held by the organizer is not directly provided to the exhibitor terminal device 6 . As a result, if the exhibitor does not know the users who visited its exhibition booth, even if the personal information of all users who visited the event is not provided to this exhibitor, this exhibitor's It is possible to generate second action history information only for users who have visited the exhibition booth. Therefore, it is possible to reduce the risk of leakage of personal information due to unnecessary personal information being provided to exhibitors.

The second action history information generated in the process shown in FIG. 7 may be the action history for all targets (products, services, etc.) or the action history for a specific target. In the latter case, the exhibitor terminal device 6 designates one or more first target IDs indicating this specific target when requesting the second action history information from the host server 3 in step ST300. When providing the information providing server 1 with the first user IDs and personal information of one or more users in step ST310, the organizer server 3 uses the one or more first target IDs (specific target IDs) specified in step ST300. (first target ID) is similarly specified. When the information providing server 1 reads out the first action history information from the storage device 4 in step ST320, the specified one or more first target IDs (first target IDs of specific targets) are included, and step ST315 The first action history information containing the first user IDs of the one or more users acquired in step 1 is read. This makes it possible to analyze the behavior history of a specific target together with personal information, making it easier to obtain useful knowledge about the characteristics of behavior according to the attributes of the user.

As described above, according to this embodiment, the first action history information including the first user ID that identifies the user as an anonymous individual and the action information is recorded in the action history DB 21 . When the host server 3 requests information about the user's action history, based on the first action history information recorded in the action history DB 21, each user's action including the action information of the first action history information Information about the history is generated and provided to the organizer server 3 . This makes it possible to provide information about the user's action history while avoiding handling personal information.

It should be noted that the present invention is not limited to the above-described embodiments, and includes various variations.

For example, the optical codes (C1, C2) illustrated in the above embodiments may be at least partially encrypted. As a result, the risk of forgery of identification information (unauthorized impersonation of a user, etc.) can be reduced.

Although the second user ID and the second target ID are each information related to the optical code in the above-described embodiment, the present invention is not limited to this example. In another embodiment of the present invention, at least one of the second user ID and the second target ID is a relatively short-range wireless communication such as NFC (near field communication) or BLE (bluetooth low energy) (registered trademark). It may be identification information transmitted by a communication technology. Further, in still another embodiment of the present invention, at least one of the second user ID and the second object ID may be a character string or symbol read by any image recognition technology.

2A and 3A, the user identification information (first user ID) included in the first action history information of the action history DB 21 is the user identification information included in the user information of the user DB 41. Although it is the same as (first user ID), the present invention is not limited to this example. In another embodiment of the present invention, the identification information of the user included in the user information of the user DB 41 to which arbitrary information is added is the user's identification information included in the first action history information of the action history DB 21. It may be used as identification information (first user ID).

When the information providing server 1 provides first action history information recorded in the action history DB 21 of the storage device 2, or provides second action history information combining the first action history information and personal information, You may output as a file of various file formats (CSV, JSON, XML, etc.).

The information providing server 1 may have an API (application programming interface) for providing the host server 3 or the like with the latest first action history information recorded in the action history DB 21 of the storage device 2 at any time.
The invention described in the scope of claims at the time of filing of the present application will be additionally described below.
