  FIG. 7 is a sequence diagram showing an operation of the information processing system shown in FIG.

  Referring to FIG. 7, the browser terminal 620 transmits a web page (content) request 503 to the content disclosure device 630.

  Next, in response to the received web page request 503, the content disclosure apparatus 630 transmits web page information 504 to the browser terminal 620. The web page information 504 is, for example, a diary, a photo, a blog, a tweet, or the like written in HTML (HyperText Markup Language).

  Next, the browser terminal 620 displays the web page on the display based on the received web page information 504.

  Subsequently, the browser terminal 620 determines target disclosure information 5131 (see FIG. 5) based on the content information included in the received web page information 504 and the viewer information held in a built-in storage unit (not shown). 11) A disclosure information request 5061 (FIG. 8) for requesting is generated. Then, the browser terminal 620 transmits the disclosure information request 5061 to the information disclosure control apparatus 100.

  FIG. 11 is a diagram illustrating an example of the disclosure information 5131. Referring to FIG. 11, the disclosure information 5131 is information [friends] indicating the relationship between the viewer and the creator of the content, and a creator identifier [alice] indicating the creator of the content. Note that the disclosure information may be a user attribute such as a name or a nickname that is accessible only to a viewer.

  FIG. 8 is a diagram illustrating an example of the disclosure information request 5061 according to the present embodiment. Referring to FIG. 8, disclosure information request 5061 includes, for example, viewer information and content information. The viewer information includes a viewer identifier (for example, “bob”) and a site identifier instructed by the viewer (first site identifier, for example, “http://tt.com/”). Further, the content information includes a user identifier for each site (for example, “hyperlice”) and a site identifier (second site identifier of the website (second website) where the content is registered (for example, “http: /// /Yyy.com/ ").

  Next, as illustrated in FIG. 7, the information disclosure control device 100 generates a relationship information request 5071 based on the disclosure information request 5061 and transmits the relationship information request 5071 to the relationship information storage device 640. Note that the operation of processing for generating and transmitting the relationship information request 5071 will be described in detail in the description of the operation of the information disclosure control apparatus 100 described later.

  FIG. 9 is a diagram illustrating an example of the relationship information request 5071 according to the present embodiment. Referring to FIG. 9, the relationship information request 5071 includes, for example, a site identifier (first site identifier, “http://tt.com/”) designated by the viewer and a viewer identifier (“bob”). .

  Next, the relationship information storage device 640 generates relationship information 5081 based on the received relationship information request 5071. The relationship information storage device 640 transmits the generated relationship information 5081 to the information disclosure control device 100.

  FIG. 10 is a diagram illustrating an example of the relationship information 5081 of the present embodiment. Referring to FIG. 10, the relationship information 5081 includes user identifiers for each site on the relationship information storage device 640 (for example, “superalice” and “carol”) and site identifiers (for example, “http://tt.com/”). ). Here, the user identifier for each site is the user identifier for each site of the creator who has a specific relationship (for example, friend relationship) with the viewer in the relationship information storage device 640. In other words, the relationship information 5081 is information indicating a specific relationship between the creator identified by the site-specific user identifier and the viewer.

  In the present embodiment, the specific relationship between the creator and the viewer is described as a “friend relationship”. That is, the relationship information storage device 640 transmits to the information disclosure control device 100 the relationship information 5081 including information specifying the user specified based on the relationship information request 5071 and the user who is in the “friend relationship”. The information disclosure control apparatus 100 operates as if the user specified by the received relationship information 5081 is in a “friend relationship” with the user specified based on the relationship information request 5071. For example, the information disclosure control apparatus 100 may hold in a storage unit (not shown) that the specific relationship between the creator and the viewer is “friend relationship”.

  For example, the relationship information storage device 640 generates the relationship information 5081 as follows. First, the relationship information storage device 640 acquires a viewer identifier (“bob”) included in the received relationship information request 5071. Next, the relationship information storage device 640 refers to the social graph 641 shown in FIG.

  FIG. 12 is a diagram illustrating an example of the social graph 641 held by the relationship information storage device 640. Referring to FIG. 12, the social graph 641 includes a set of each user identifier (first user identifier) on the relational information storage device 640 and another user identifier (second user identifier). Here, the other user identifier is a second user identifier that specifies a user having a specific relationship (for example, a friend relationship) with the user specified by the first user identifier.

  The relationship information storage device 640 refers to the social graph 641 to regard the viewer identifier (“bob”) acquired from the relationship information request 5071 as the first user identifier, and the first user identifier “bob”. The second user identifier ("superalice" and "carol") corresponding to is acquired. Next, the relationship information storage device 640 integrates the acquired second user identifier and the site identifier (“http://tt.com/”) included in the relationship information request 5071, as shown in FIG. Relationship information 5081 is generated.

  Note that the relationship information request 5071 and the relationship information 5081 do not have to include a site identifier. In this case, the information disclosure control apparatus 100 operates so that the relationship information request 5071 and the relationship information 5081 as a response can be synchronized. For example, the information disclosure control apparatus 100 operates to transmit the next relation information request 5071 after transmitting the relation information request 5071 and receiving the relation information 5081 as a response.

  Note that the relationship information storage device 640 may store user relationship information of other websites in addition to the user relationship information of its own website.

  Further, when the relationship information storage device 640 stores only the user relationship information of its own website, the relationship information request 5071 and the relationship information 5081 may not include the site identifier. When the relationship information storage device 640 stores only the user relationship information of its own website, for example, the relationship information storage device 640 identified by “http://tt.com/” transmits the relationship information. This is a case where the included site identifier is always “http://tt.com/”.

  Note that the relationship information storage device 640 may create the relationship information with reference to, for example, matching user information instead of the social graph 641. FIG. 20 is a diagram illustrating an example of the matching user information 642. As shown in FIG. 20, the matching user information 642 includes user attribute information (company name, department name) corresponding to the user identifier. Then, the relationship information storage device 640 creates relationship information by regarding users who have the same attribute information regarding the company name and department name as “acquaintances”, for example.

  Next, the information disclosure control apparatus 100 generates disclosure information 5131 (“friend“ alice ””) based on the received relationship information 5081, and transmits the disclosure information 5131 to the viewer terminal 620.

Specifically, the site identifier [http: // yyy. The creator identifier “alice” corresponding to “com /] and the site-specific user identifier [hyperlice]” is acquired from the account list 141.

  Next, the disclosure determination unit 120 determines whether or not the creator identifier has been acquired (step S612). If it can be obtained (YES in step S612), the process proceeds to step S613. If not acquired (NO in step S612), the process proceeds to step S620.

  Next, the disclosure determination unit 120 refers to the account list 141 and acquires a set of a corresponding site identifier and user identifier for each site based on the acquired creator identifier (step S613).

  For example, in the case of the account list 141 illustrated in FIG. 2, the disclosure determination unit 120 sets “http://tt.com/” and “ a set of “superice”, a set of “http://mmm.com/” and “superalice”, a set of “http://hh.jp/” and “superalice”, and “http://yyy.com” / "And" hyperalice "set.

  Next, the disclosure determination unit 120 determines whether a set of a site identifier and a site-specific user identifier has been acquired (step S614). If it can be obtained (YES in step S614), the process proceeds to step S615. If not acquired (NO in step S614), the process proceeds to step S620.

  Next, the disclosure determining unit 120 sets the combination of the site identifier and the site-specific user identifier of the relationship information 5081 included in the determination request among one or more sets of the site identifier and the site-specific user identifier acquired in step S613. And a set of matching site identifiers and user identifiers for each site are acquired. Subsequently, the disclosure determination unit 120 refers to the disclosure policy 131 and acquires disclosure permission information corresponding to the set of the acquired site identifier and user identifier for each site (step S615). For example, the disclosure determining unit 120 matches the site identifier and site user identifier pair of the relationship information 5081 included in the determination request (a group of “http://tt.com/” and “superalice”). A set of identifiers and user identifiers for each site (a set of “http://tt.com/” and “superlice”) is acquired. Subsequently, the disclosure determination unit 120 sets the disclosure permission information (“friend” to the friend) corresponding to the set of matching site identifiers and user identifiers for each site (the set of “http://tt.com/” and “superlicice”). Disclosure is possible ”).

  Next, the disclosure determination unit 120 determines whether disclosure permission information has been acquired (step S616). If it can be obtained (YES in step S616), the process proceeds to step S613. If not acquired (NO in step S616), the process proceeds to step S620.

  Next, the disclosure determination unit 120 determines whether to disclose the disclosure information based on the content of the acquired disclosure permission information and the relationship information 5081 included in the determination request 5091 (FIG. 15) (step S617). ). Specifically, the disclosure determination unit 120 determines whether or not the acquired disclosure permission information includes a specific relationship. Here, the specific relationship is a relationship between the creator and the viewer corresponding to the user identifier for each site indicated by the relationship information 5081 included in the determination request 5091.

  For example, it is assumed that the relationship information request 5071 is “[http://tt.com/][bob]”. Further, it is assumed that the relationship information 5081 is “[http://tt.com/][superalice] and [http://tt.com/][carol]”. Further, it is assumed that the specific relationship between the creator and the viewer corresponding to the site-specific user identifier indicated by the relationship information 5081 is “friend relationship”. In this case, the viewer specified by “bob” and the creator [alice] specified by [superalice] have a friendship. Therefore, for example, when the content indicated by the disclosure permission information is “can be disclosed to friends”, the disclosure determination unit 120 determines that disclosure is possible.

  If it is determined to be disclosed (that is, included) (YES in step S617), the disclosure determining unit 120 generates disclosure information 5131 (for example, “friend“ alice ””) and transmits it to the viewer terminal 620. (Step S618). If it is determined not to be disclosed (that is, not included) (NO in step S617), the process proceeds to step S620.

  In step S620, the disclosure determination unit 120 generates non-disclosure information (for example, “others”) and transmits it to the viewer terminal 620 (step S620).

  The operation of the information disclosure control apparatus 100 has been described above.
