[1. Embodiment]
[1-1. Presentation process according to the embodiment]
First, an example of the presentation process according to the embodiment will be described with reference to FIG. FIG. 1 is an explanatory diagram showing an example of presentation processing by the presentation system 1 according to the embodiment. In the example of FIG. 1, the presentation process of presenting the update information of the content belonging to the field of interest to the user U1 to the terminal device 10 of the user U1 is performed.

As shown in FIG. 1, the presentation system 1 includes a terminal device 10, an information providing device 50, and a presentation device 100 (corresponding to an example of a determination device). The terminal device 10, the information providing device 50, and the presenting device 100 are each communicably connected to the network by wire or wirelessly.

The terminal device 10 is an information processing device such as a smartphone, a tablet terminal, a PC (Personal Computer), a mobile phone, or a PDA (Personal Digital Assistant). For example, when the content is updated, the terminal device 10 receives and displays the update information of the content. As an example, the terminal device 10 receives and displays updated information of content belonging to a field of interest to the user U1 (for example, content acquired by an application installed in the terminal device 10).

The information providing device 50 is a server device that provides contents. For example, the information providing device 50 provides contents belonging to various fields such as "idle" and "operation information". As an example, the information providing device 50 provides the content update information to the terminal device 10 via the presenting device 100.

The presenting device 100 is a server device that presents information related to content update to the terminal device 10. For example, the presentation device 100 transmits instruction information for displaying a push notification regarding update information of the content belonging to the field of interest to the user U1 on the terminal device 10.

Here, it is desired that the push notification appropriately presents the update information to the user. For example, it is desirable that the push notification presents update information that is preferable for the user U1 to be displayed, and does not present update information that is not desirable for the user U1 to display. Therefore, the presentation device 100 executes a presentation process of presenting the updated information of the content in a presentation method based on the information about the field in which the user U1 is interested.

First, the case of update information that is not preferable for the user U1 to be displayed will be described. In other words, the case of update information that the user U1 does not want others to know about will be described. Specifically, first, the presentation device 100 acquires the update information of the content belonging to the field "idle" (step S11). Here, as shown in FIG. 1, the presentation device 100 acquires the update information UD1 such as "Updated at 17:00 on July 11th, the concert video of the idol W starts to be distributed from August 10th" from the information providing device 50.

After that, the presentation device 100 acquires information about the field "idle" in which the user U1 is interested. Specifically, the presentation device 100 acquires the degree of secrecy for the user U1 in the field "idle" as information about the field "idle" in which the user U1 is interested.

Here, the degree of secrecy is, for example, an index calculated based on the time and place where the user is browsing the content belonging to the field. As an example, confidentiality is calculated higher as users often browse content during midnight rather than daytime. In another example, confidentiality is calculated higher as users often browse content at home rather than at work.

Subsequently, the presentation device 100 determines the presentation method of the content update information UD1 corresponding to the field "idle" based on the acquired information about the field "idle". Specifically, the presentation device 100 determines the presentation method of the content update information UD1 based on the degree of confidentiality for the user U1 in the acquired field "idle". For example, the presentation device 100 is a presentation method in which at least a part of the update information of the content corresponding to the field "idle" is hidden when the degree of confidentiality for the user U1 in the acquired field "idle" is equal to or higher than a predetermined threshold value. To decide. Here, in the field "idle", it is assumed that the degree of secrecy for the user U1 is equal to or higher than a predetermined threshold value. In this case, the presentation device 100 determines the presentation method for the content update information UD1 belonging to the "idle" field, in which the content is hidden and only the number of update information is presented.

Then, the presenting device 100 transmits the instruction information of the push notification presenting the number of update information to the terminal device 10 (step S12). As a result, as shown in FIG. 1, the terminal device 10 displays the push notification Pu1 that presents only the number of update information such as "There is one update information."

Next, the case of update information that is preferable for the user U1 to be displayed will be described. In other words, the case of update information whose contents may be known to others for the user U1 will be described. Specifically, first, the presentation device 100 acquires the update information of the content belonging to the field "operation information" (step S21). Here, as shown in FIG. 1, the presenting device 100 updates the update information UD2 such as "The line X is updated from 17:00 on July 11 due to the influence of the signal failure" from 17:00 between the A station and the B station. " It shall be acquired from the information providing device 50.

After that, the presentation device 100 acquires the degree of secrecy for the user U1 in the field "operation information" as information regarding the field "operation information" that the user U1 is interested in. Subsequently, the presentation device 100 determines the presentation method of the content update information UD2 based on the degree of confidentiality for the user U1 in the acquired field "operation information". For example, the presentation device 100 determines the presentation method for presenting a summary of the update information when the degree of confidentiality for the user U1 in the acquired field "operation information" is less than a predetermined threshold value. Here, in the field "operation information", it is assumed that the degree of confidentiality for the user U1 is less than a predetermined threshold value. In this case, the presentation device 100 determines the presentation method for displaying the update information UD2 of the content belonging to the field of "operation information", such as the time when the operation is stopped, the route, and the section.

Then, the presenting device 100 transmits the instruction information of the push notification displaying a part of the operation information to the terminal device 10 (step S22). As a result, as shown in FIG. 1, the terminal device 10 presents the icon IC2 of the application that provides the operation information and the information such as "July 11, 17:00 X-ray A station to B station operation stop". Display the push notification Pu2.

In this way, the presentation device 100 according to the embodiment acquires information about the field in which the user is interested. Further, the presentation device 100 determines a method of presenting update information of the content corresponding to the field based on the degree of confidentiality for the user in the acquired field.

As a result, the presenting device 100 can determine the presentation method of the content update information based on the field of interest to the user and display it on the terminal device 10, so that the update information is appropriately presented to the user. be able to. For example, the presentation device 100 can prevent the content of the updated information of the content belonging to the field that the user wants to keep secret from being displayed, so that the user's privacy can be protected. On the other hand, since the presentation device 100 can display the content of the updated information of the content belonging to the field that does not need to be kept secret to the user, the content of the updated information can be transmitted to the user in real time.

Although FIG. 1 shows an example in which the presentation system 1 includes one terminal device 10, one information providing device 50, and one presentation device 100, the presentation system 1 includes an example. A plurality of terminal devices 10, a plurality of information providing devices 50, and a plurality of presenting devices 100 may be included.

The presentation device 100 according to the above-described embodiment may be implemented in various different forms other than the above-described embodiment. Therefore, in the following, another embodiment of the above-mentioned presentation device 100 will be described.

[2-1. Presentation method based on action history]
In the above embodiment, an example has been described in which the presentation device 100 determines a method of presenting update information of the content corresponding to the field based on the degree of confidentiality for the user in the field acquired by the acquisition unit 131. Here, the presentation device 100 may determine the presentation method based on various types of information.

Specifically, the determination unit 132 of the presentation device 100 determines the presentation method of the content update information based on the degree of confidentiality based on the user's action history. For example, the presentation device 100 determines a method of presenting content update information based on a user's search history, browsing history, purchase history, application usage history, or posting history to SNS as a user's action history. In other words, the degree of secrecy is calculated based on the user's search history, browsing history, purchase history, application usage history, posting history to SNS, and the like.

In one aspect, in the presentation device 100, the content update information is information related to a keyword searched by the user within a predetermined time from the current time, a keyword frequently appearing on a browsed Web page, and a keyword related to a purchased product. In this case, the presentation method is determined to display a part of the update information of the content. This is because when the updated information of the content is the information most recently related to the user, it is considered that it is often more convenient for the user to display the updated information. On the other hand, the presentation device 100 determines the presentation method in which the update information of the content is hidden when the update information of the content is information that is not most recently related to the user.

In another aspect, the presentation device 100 displays a part of the content update information when the user uses the application that provides the content update information within a predetermined time from the current time. To decide. This is because it is considered more convenient for the user to display the update information of the application that the user has been using most recently. On the other hand, the presentation device 100 determines the presentation method in which the update information of the content is hidden when the user has not recently used the application that provides the update information of the content.

As another aspect, the presentation device 100 is determined to be a presentation method for displaying a part of the content update information when the update information is related to the content posted on the SNS, which is generally used by the user. To do. This is because such updated information is considered to be information that may be known to others by the user. On the other hand, the presentation device 100 hides a part of the content update information when the update information is related to the content posted on the SNS or the anonymity bulletin board where the user generally uses a pseudonym such as a nickname. Decide on the presentation method. This is because such updated information is considered to be information that the user does not want others to know. Further, the presentation device 100 may decide on a presentation method for displaying a part of the update information of the content when the update information is related to the content shared with another user by the message application or the like.

As another aspect, the presentation device 100 determines the presentation method in which the update information of the content is hidden when the user behaves differently from usual. This is because it is highly likely that user behavior that is different from usual is information that is not desired to be known to others. The presentation device 100 may be determined to be a presentation method for displaying a part of the content update information when the user behaves differently than usual. This is because if the user behaves differently than usual, it may be more convenient to display the information that the user is newly interested in.

In another example, the presentation device 100 determines a method of presenting content update information based on the time when the user acts, the place where the user stays, or the information that the user exchanges with another user as the user's action history. To do. In other words, the degree of secrecy is calculated based on the time the user acts, the place where the user stays, the information that the user exchanges with other users, and the like.

In one aspect, the presentation device 100 determines a presentation method in which a part of the content update information is hidden when the user rarely operates the terminal device 10. This is because it is considered that there are many cases where the user is involved with another person at work or the like during the time period when the operation is relatively rare, and there is a high possibility that the other person will know when the updated information is displayed. On the other hand, the presentation device 100 determines the presentation method for displaying a part of the updated information of the content when the user operates the terminal device 10 in a relatively frequent time zone. This is because it is considered that many people spend their time alone during the time when they operate relatively frequently, and it is unlikely that others will know even if the updated information is displayed.

In another aspect, the presentation device 100 provides content update information when the place where the user stays is a place where the possibility of being viewed by others is relatively low, such as a closed room such as a home or a toilet. Decide on a presentation method that displays a part.
