  FIG. 1 is a block diagram illustrating a communication system according to a first embodiment of this invention. The communication system shown in FIG. 1 includes a user terminal 1, a secondary usage server 2, a public server 3, an administrator terminal 4, and an incident reception server 5. The user terminal 1, the secondary usage server 2, the public server 3, and the incident reception server 5 are connected to each other via a network 100 that is a global area network such as the Internet. The public server 3 and the administrator terminal 4 are connected to each other via the local area network 101. Further, the administrator terminal 4 can be connected to the network 100 via the local area network 101.

  The user terminal 1 is a PC (personal computer), a smart phone, a game machine, or the like, and is used by a general user who browses and views content published on the network 100. For browsing and viewing the content, a general-purpose application program such as a browser or a dedicated application program corresponding to the content is used. Although the number of user terminals 1 is not limited, two user terminals 1 are shown in FIG.

  The content is, for example, an image file, an audio file, a style sheet file, a script file, and a program. The image file may indicate a still image or a moving image. The still image includes, for example, an illustration, a photograph, a logo used for page design on a Web page, a decorative image, and the like.

  In the present embodiment, the content is stored in the public server 3 and published on both the secondary usage server 2 and the public server 3. At that time, the content is published using page information indicating a Web page having a link to the content. Therefore, the secondary usage server 2 and the public server 3 store page information indicating a Web page having a link to content, as will be described later. Hereinafter, the page information stored in the public server 3 may be referred to as regular page information, and the page information stored in the secondary usage server 2 may be referred to as secondary page information. The Web page is described using html (HyperText Markup Language) or the like.

  FIG. 2 is a diagram illustrating an example of regular page information stored in the public server 3. The regular page information 200 shown in FIG. 2 includes a URL (Uniform Resource Locator) including a path “a **. Jp” and a file name “index.html” corresponding to the public server 3 as position information indicating a position on the network 100. ) And includes link information 201 indicating a link to the content. A path is sometimes called a domain. Also, the path may include the name of the folder (folder name) in which the content is stored. The content linked by the link information 201 is an image file having the file name “content.jpg”, and the link information 201 is an image display tag that is an html tag for displaying an image. Since the content is stored in the public server 3, the content has the same path “a **. Jp” as the regular page information 200. For this reason, the link information 201 indicates a link to the content using a relative path (“content.jpg”).

  Note that the link based on the link information in the present embodiment displays a Web page different from the Web page by an operation such as clicking on the Web page displayed on the display unit (not shown) of the user terminal 1. This is not a hyperlink, but a position on the network 100 where content displayed (or executed within the Web page) indicated by the page information received in response to the browsing request is stored. is there. However, the link based on the link information may be a hyperlink as long as the usage status of the content can be detected by the public server 3 as described later.

  FIG. 3 is a diagram illustrating an example of secondary page information stored in the secondary usage server 2. The secondary page information 300 illustrated in FIG. 3 includes a URL including a path “b **. Jp” and a file name “index.html” corresponding to the secondary usage server 2 as position information indicating a position on the network 100. It has a page file. The secondary page information 300 includes link information 301 indicating a link to the same content as the content linked by the link information 201 in the regular page information 200 shown in FIG. The link information 301 is an image display tag like the link information 201. Since the content is stored in the public server 3 and has a path “a **. Jp” different from that of the secondary usage server 2, the link information 301 includes an absolute path (“a **. Jp / content.jpg”). ) Is used to indicate a link to the content.

  Returning to the description of FIG. The user terminal 1 transmits a page information browsing request to at least one of the secondary usage server 2 and the public server 3. The browsing request includes a URL that is position information of the page information on the network 100. The user terminal 1 receives page information corresponding to the transmitted browsing request, that is, page information indicated by a URL in the browsing request.

  The user terminal 1 transmits a content acquisition request linked to the received page information to a transmission destination corresponding to the link. In the present embodiment, since the content is stored in the public server 3, the user terminal 1 transmits an acquisition request to the public server 3. The acquisition request includes identification information for specifying the content, location information indicating the location of the content on the network 100, and referrer information indicating the link source of the content. In this embodiment, the identification information is a file name of the content, and the identification information and the position information are collectively shown by a URL. The referrer information indicates the URL (“a **. Jpg / index.html” or “b **. Jp / index.html”) of the page information that triggered the transmission of the acquisition request as the link source.

  When receiving the content corresponding to the acquisition request, that is, the content indicated by the URL in the acquisition request, the user terminal 1 outputs the content. The output of the content includes display of an image file, audio output of an audio file, and the like.

  The secondary usage server 2 is, for example, a computer device such as a Web server. The secondary usage server 2 stores secondary page information indicating a Web page having a link to content published on the public server 3. The secondary page information includes regular secondary page information in which a link to the content is permitted by the administrator of the public server 3, and non-regular secondary information in which a link to the content is not permitted by the administrator of the public server 3. There is information on the next page. The non-regular secondary page information includes page information for using the content for an illegal purpose. As such illegal page information, for example, a site that provides content for a fee without permission to the administrator of the public server 3, an advertisement is displayed together with the content without permission to the administrator of the public server 3, and an advertising fee such as an affiliate is earned Examples of the page information include a site and a site that steals personal information such as an ID and a password from a general user by impersonating a Web page indicated by regular page information using content. In addition, non-regular secondary page information is not necessarily illegal page information. For example, a translation in which a sentence in a web page is translated and translated into a web page with the same page design as the web page Also includes page information used on the site.

  When receiving the browsing request from the user terminal 1, the secondary usage server 2 transmits the stored secondary page information to the user terminal 1 in response to the browsing request.

  The public server 3 is a server that publishes content, and is configured by a computer device such as a Web server, for example. In the present embodiment, the public server 3 also has a function of a content usage detection device that detects the usage status of content. FIG. 4 is a block diagram illustrating an example of the configuration of the public server 3. The public server 3 illustrated in FIG. 4 includes a storage unit 31, a communication unit 32, a control unit 33, and a search unit 34.

  The storage unit 31 stores content, page information indicating a Web page having a link to the content (regular page information), and history information of an acquisition request for the content. There may be a plurality of contents and page information.

  In this embodiment, the history information is an access log for content, and includes at least referrer information indicating a link source of an acquisition request for content. More specifically, the history information indicates referrer information indicating the link source of the acquisition request for the content for each piece of identification information for specifying the content. The history information may further indicate the IP address of the user terminal 1 that transmitted the acquisition request, the use date and time that is the date and time when the acquisition request is received, and the like. The history information may further indicate the referrer information indicating the link source of the browsing request for the page information, the IP address of the user terminal 1 that has transmitted the browsing request, the use date and time when the browsing request is received, and the like.

  FIG. 5 is a diagram illustrating an example of history information. The history information 500 illustrated in FIG. 5 includes an IP address 501, a date and time 502, a file name 503, and a referrer 504. The IP address 501 is an IP address assigned to the user terminal 1 that has transmitted an acquisition request for content. The date and time 502 is a use date and time when an acquisition request for content is received. The file name 503 is content identification information, and is a name set for the content. The referrer 504 is referrer information indicating a link source of an acquisition request for content. In the example of FIG. 5, the referrer 504 includes the URL “a **. Jp / index.html” of the regular page information stored in the storage unit 31 of the public server 3 or the second stored in the secondary usage server 2. Indicates the URL “b **. Jp / index.html” of the next page information. When there is no link source for an acquisition request for content, such as when the user of the user terminal 1 directly inputs a URL to the user terminal 1, the referrer 504 is blank.

  The communication unit 32 communicates with the user terminal 1 and the like via the network 100. For example, the communication unit 32 receives a browsing request and an acquisition request from the user terminal 1.

  The control unit 33 controls the entire public server 3. For example, when the communication unit 32 receives a browsing request, the control unit 33 transmits page information corresponding to the browsing request among the page information stored in the storage unit 31 to the user terminal 1. The page information corresponding to the browsing request is page information indicated by the URL included in the browsing request. When the communication unit 32 receives an acquisition request, the control unit 33 transmits content corresponding to the acquisition request among the content stored in the storage unit 31 to the user terminal 1. The content corresponding to the acquisition request is content specified by the URL included in the acquisition request.

  In addition, the control unit 33 updates the history information stored in the storage unit 31 in response to the acquisition request. For example, in the case of the history information 500 illustrated in FIG. 5, the control unit 33 generates the date and time when the acquisition request is received as the date and time 502, and sets the IP address, file name, and referrer information included in the acquisition request to the IP address 501, respectively. The file name 503 and the referrer 504 are generated. Then, the IP address 501, the date / time 502, the file name 503, and the referrer 504 are associated with each other and added to the history information stored in the storage unit 31. Note that the control unit 33 may update the history information in response to the browsing request. In this case, the history information update process is the same as the update process in response to the acquisition request.

  The search unit 34 searches for referrer information satisfying a predetermined detection condition from the history information stored in the storage unit 31. In this embodiment, the search condition is that the referrer information corresponds to a predetermined file name, and that the referrer information indicates a link source other than the predetermined link source. In this case, search condition information indicating a predetermined file name and a predetermined link source is stored in the storage unit 31. The search unit 34 searches the history information for referrer information corresponding to the file name indicated by the search condition information stored in the storage unit 31 and indicating a ring source other than the link source indicated by the search condition information. The search condition may be that the referrer information indicates a predetermined link source.

  In the present embodiment, the predetermined file name is a file name of predetermined content. That is, the predetermined file name does not include the file name of the page information. Further, the number of predetermined file names is not limited. When links to different contents are included in one page information, it is not necessary to set all the file names of those contents to a predetermined file name, and at least one file name of those contents is a predetermined file name. It can be. For example, if the page information indicates a Web page that displays thumbnail images of each video on a site that provides a plurality of videos, the predetermined file name is a video that is not desired for secondary use without permission. Including at least a file name of an image indicating a thumbnail of the image. For example, when the page information indicates an input screen for logging in by inputting a login name or a password, the predetermined file name includes at least the file name of an image indicating a “login button” for logging in.

  The predetermined link source indicates, for example, regular page information stored in the storage unit 31 of the public server 3. In addition to the regular page information, or in place of the regular page information, the predetermined link source may represent regular secondary page information that the administrator of the public server 3 permits the use of the content. .

  The search timing at which the search unit 34 searches for referrer information is not particularly limited. For example, the search unit 34 searches for referrer information periodically (for example, every hour). In this case, the search unit 34 may search the referrer information satisfying a predetermined detection condition from the history information including the use date and time from the previous search timing to the present among the history information. The search timing may be a timing at which the control unit 33 updates the history information.

  When searching for referrer information that satisfies a predetermined detection condition, the search unit 34 executes processing according to the search result. For example, the search unit 34 stores the search result in the storage unit 31. When the referrer information satisfying the predetermined detection condition is found, the search unit 34 outputs notification information indicating that the referrer information satisfying the predetermined detection condition has been found. The notification information desirably includes referrer information that satisfies a predetermined detection condition. Moreover, the output of notification information is, for example, transmission to a predetermined destination. Moreover, if the public server 3 includes a display unit, the notification information may be output by displaying the notification information on the display unit. In the present embodiment, when the search unit 34 finds referrer information that satisfies a predetermined detection condition, the search unit 34 transmits notification information including the referrer information that satisfies a predetermined detection condition to the administrator terminal 4 as a predetermined destination.

  The administrator terminal 4 is used by the administrator of the public server 3. The administrator terminal 4 receives notification information from the public server 3 and executes processing such as notifying the administrator of the notification information. At this time, the administrator confirms the notification information, and if necessary, sends a deletion request from the administrator terminal 4 to the incident reception server that requests deletion of the page information that is the link source indicated by the referrer information included in the notification information. Send to 5. Although the administrator terminal 4 is connected to the incident reception server 5 (network 100) via the public server 3 in the example of FIG. 1, the incident reception server 5 (network 100) is not connected via the public server 3. And may be connected.

  The incident reception server 5 is managed by a predetermined organization that requests the administrator of a server that discloses an unauthorized site to delete the unauthorized site. When the incident reception server 5 receives the deletion request, the incident reception server 5 executes processing such as notifying the administrator of the incident reception server 5 of the deletion request. At this time, the administrator confirms the notification information, and if necessary, the administrator of the server (secondary usage server 2) that is requested to be deleted by the deletion request and discloses the page information to the administrator. Request deletion of page information.

  Next, the operation will be described. 6 and 7 are sequence diagrams for explaining the operation of the communication system of the present embodiment.

  In the example of FIG. 6, first, the user terminal 1 transmits a browsing request according to an instruction or the like from a general user who uses the user terminal 1. Here, it is assumed that the user terminal 1 transmits a browsing request to the public server 3 via the network 100 (step S1). In this case, the communication unit 32 of the public server 3 receives the browsing request and transmits the browsing request to the control unit 33. When receiving the browsing request, the control unit 33 acquires regular page information corresponding to the browsing request from the storage unit 31 and transmits the regular page information to the user terminal 1 via the communication unit 32 and the network 100 ( Step S2).

  Upon receiving the regular page information, the user terminal 1 displays the Web page indicated by the regular page information on the display unit of the user terminal 1, and generates an acquisition request corresponding to the link to the content included in the regular page information And it transmits to the public server 3 via the network 100 (step S3).

  The communication unit 32 of the public server 3 receives the acquisition request and transmits the acquisition request to the control unit 33. When receiving the acquisition request, the control unit 33 acquires content corresponding to the acquisition request from the storage unit 31 and transmits the content to the user terminal 1 via the communication unit 32 and the network 100. When receiving the content, the user terminal 1 outputs the content (step S4). The content output is, for example, display of an image file at a position defined by the regular page information on the Web page indicated by the regular page information when the content is an image file.

  When the content is transmitted in step S4, the control unit 33 updates the history information stored in the storage unit 31 in response to the acquisition request (step S5).

  Further, when the search timing comes, the search unit 34 of the public server 3 searches the history information stored in the storage unit 31 for content names and referrer information that satisfy a predetermined detection condition (step S6). Here, since the referrer information corresponding to the predetermined content name is regular page information that is a predetermined link source, it is assumed that the referrer information that satisfies the predetermined detection condition is not found. In this case, the search unit 34 stands by until the next search timing (step S7).

  In the example of FIG. 7, the user terminal 1 transmits a browsing request to the secondary usage server 2 via the network 100 (step S1a). In this case, the secondary usage server 2 receives the browsing request and transmits secondary page information corresponding to the browsing request to the user terminal 1 via the communication unit 32 and the network 100 (step S2a).

  Upon receiving the secondary page information, the user terminal 1 displays the Web page indicated by the secondary page information on the display unit of the user terminal 1 and obtains according to the link to the content included in the secondary page information A request is generated and transmitted to the public server 3 via the network 100 (step S3a).

  The communication unit 32 of the public server 3 receives the acquisition request and transmits the acquisition request to the control unit 33. When receiving the acquisition request, the control unit 33 acquires content corresponding to the acquisition request from the storage unit 31 and transmits the content to the user terminal 1 via the communication unit 32 and the network 100. When receiving the content, the user terminal 1 outputs the content (step S4a).

  When the content is transmitted, the control unit 33 updates the history information stored in the storage unit 31 in response to the acquisition request (step S5a).

  Further, when the search timing comes, the search unit 34 of the public server 3 searches the history information stored in the storage unit 31 for content names and referrer information that satisfy a predetermined detection condition (step S6a). Here, since the referrer information for a predetermined content name is secondary page information that is not a predetermined link source, it is assumed that referrer information satisfying a predetermined detection condition is found. In this case, the search unit 34 generates notification information including the found referrer information, transmits it to the administrator terminal 4 via the local area network 101, and waits until the next search timing (step S8).

  When receiving the notification information, the manager terminal 4 notifies the manager of the notice information (step S9). Thereafter, a deletion request is transmitted to the incident reception server 5 via the local area network 101 and the network 100 in accordance with an instruction from the administrator of the administrator terminal 4. When the incident reception server 5 receives the deletion request, the incident reception server 5 notifies the administrator of the incident reception server 5 of the deletion request. Then, the administrator of the incident reception server 5 confirms the notification information, and if necessary, the administrator of the server (secondary usage server 2) that has been requested to be deleted by the deletion request and discloses the page information. On the other hand, deletion of the page information is requested (step S10).

  As described above, according to the present embodiment, the storage unit 31 stores the referrer information indicating the link source of the acquisition request as the acquisition request history information for the published content. The search unit 34 searches for referrer information satisfying a predetermined search condition from the history information. In this case, since the referrer information satisfying the search condition is searched, it is possible to grasp the usage status of the content that is secondarily used by establishing a link. In addition, since it is not necessary to embed a digital watermark or the like in the content, it is possible to easily grasp the usage status of the content.

  In the present embodiment, the predetermined search condition is that the referrer information indicates a link source other than the predetermined link source. In this case, it is possible to detect an unauthorized Web page easily and quickly because it is possible to detect that the content is used on an unauthorized Web page by appropriately setting a predetermined link source. become.

(Second Embodiment)
In the first embodiment, the control unit 33 of the public server 3 updates the history information in response to the acquisition request, and when the search unit 34 comes to the search timing, the referrer information satisfying a predetermined detection condition is obtained from the history information. searched. In the present embodiment, when the search unit 34 of the public server 3 finds referrer information satisfying a predetermined search condition from the acquisition request, the control unit 33 makes an acquisition request corresponding to the referrer information satisfying the predetermined search condition. In response, the history information is updated.

  Hereinafter, the difference from the first embodiment will be specifically described. The points not described are the same as in the first embodiment.

  In the present embodiment, when the communication unit 32 of the public server 3 receives the acquisition request, the control unit 33 transmits content corresponding to the acquisition request among the content stored in the storage unit 31 to the user terminal 1. When the control unit 33 transmits content corresponding to the acquisition request, the search unit 34 searches for referrer information satisfying a predetermined search condition from the file name and the referrer information included in the acquisition request. When the search unit 34 finds referrer information satisfying a predetermined search condition, the control unit 33 displays the history information stored in the storage unit 31 in response to an acquisition request corresponding to the referrer information satisfying the predetermined search condition. Update. The items of information stored in the history information are the same as those in the first embodiment. However, the history information of the first embodiment also includes referrer information that does not satisfy a predetermined search condition, but the history information of the present embodiment includes only information that includes referrer information that satisfies a predetermined search condition. This is different from the history information of the first embodiment.

  Further, the search unit 34 transmits the history information added after the previous search timing to the administrator terminal 4 from the history information stored in the storage unit 31 at a predetermined search timing. The predetermined search timing may be the same as or different from the search timing of the first embodiment.

(Third embodiment)
In this embodiment, when the search unit 34 of the public server 3 finds referrer information that satisfies the search condition, the search unit 34 performs a change process on the content corresponding to the referrer information. Specifically, when the search unit 34 finds referrer information satisfying the search condition, the search unit 34 changes the content corresponding to the referrer information to another file name. At this time, the search unit 34 changes the link to the content according to the changed file name (another file name) with respect to the regular page information indicating the Web page having the link to the content whose file name has been changed. Process to change. Specifically, the search unit 34 changes the link to the content of the file name before the change in the regular page information to the link to the content of the file name after the change. Further, the search unit 34 generates a content having a file name before the change of the content corresponding to the referrer information, which is different from the content corresponding to the referrer information (hereinafter referred to as “different content”). Then, it may be stored in the storage unit 31. Further, the search unit 34 may store another content in the storage unit 31 in advance, and change the file name of the other content to the file name before the change of the content corresponding to the referrer information.

  8-10 is a figure for demonstrating an example of a process of the search part 34 of this embodiment. Specifically, FIG. 8 shows an example of content, FIG. 9 shows an example of page information whose link has been changed, and FIG. 10 shows an example of another content having a file name before the change of content. . In the following description, a case will be described as an example where the change process is used to limit the use of content based on irregular secondary page information.

  In the state before finding the referrer information satisfying the search conditions, the regular page information 200 shown in FIG. 2 is stored in the storage unit 31 of the public server 3, and the secondary usage server 2 shown in FIG. Secondary page information 300 is stored. Further, the content linked by the link information 201 and 301 in the regular page information 200 and the secondary page information 300 is the content 701 shown in FIG. The content 701 is an image file.

  In the above state, the search unit 34 finds referrer information corresponding to the content 701 linked by the link information 201 and 301 and indicating the secondary page information 300 as the link source as the referrer information satisfying the search condition. Suppose. In this case, the search unit 34 changes the file name of the content 701 from “content.jpg” to another file name “content2.jpg”. As a result, the content 701 is not displayed in the regular page information 200 and the secondary page information 300. Therefore, the use of the content 701 in the secondary page information 300 of the content 701 can be suppressed. However, even the regular page information 200 cannot use the content 701.

  Therefore, the search unit 34 changes the link information 201 of the regular page information 200 to link information 202 indicating a link to the content with the changed file name “content2.jpg” as shown in FIG. As a result, the content 701 is displayed in the regular page information 200, but the link information 302 remains unchanged in the secondary page information 300, so the content 701 is not displayed.

  Further, the search unit 34 generates the content 702 shown in FIG. 10 as another content having the file name “content.jpg” before the change (or changes the file name of the content 702 stored in advance). ) And may be stored in the storage unit 31. Thereby, for example, the content 701 is displayed in the regular page information 200, but the content 702 different from the content 701 is displayed in the secondary page information 300 as shown in FIG. The content 702 is an image file in which a message “There is a possibility that the site uses content for illegal purposes” is described. As a result, it is possible to reduce the risk of content creators or general users being damaged by sites that use content for fraudulent purposes.

  In the present embodiment, the case where the change process for content is used to limit the use of the content based on the non-regular secondary page information has been described as an example. It may be used to facilitate utilization. In this case, for example, an image file in which a message that promotes the use of the content is used as content different from the content 701.

  In each embodiment described above, the illustrated configuration is merely an example, and the present invention is not limited to the configuration.

  For example, the functions of the user terminal 1, the secondary usage server 2, the public server 3, the administrator terminal 4, and the incident reception server 5 are recorded on a computer-readable recording medium as a program for realizing the functions. The program recorded on the recording medium may be read and executed by a computer.

  Further, the public server 3 that publishes content and the content usage detection device (device having a storage unit that stores history information and a search unit) may be configured as separate devices.
