Next, embodiments of the present invention will be described with reference to the drawings. An example of the configuration of the content illegal distribution countermeasure system of the present invention is shown in FIG. In FIG. 1, 100 is a content illegal distribution countermeasure system, 110 is a storage unit, 111 is content to be monitored, 112 is a keyword, 113 is illegal content, 114 is an improper posting status, 115 is pseudo illegal content, 116 is browsing data, 120 is Calculation unit, 121 is a monitoring request receiving unit, 122 is a content monitoring unit, 123 is a posting status notifying unit, 124 is a pseudo illegal content generating unit, 125 is a content distributing unit, 126 is a deletion request mail distributing unit, and 127 is a log database management Means 130 is a log database (DB).
The content illegal distribution countermeasure system 100 monitors whether or not illegal content is distributed on an Internet site that shares content such as a moving image. When an illegal distribution is detected, a countermeasure is taken against the illegal content. It is a system to do. The content illegal distribution countermeasure system 100 is realized by hardware and software of a computer system, and includes a storage unit 110, a calculation unit 120, a log database (DB) 130, and the like as shown in FIG.

The storage unit 110 is a storage unit such as a main memory or a hard disk in the computer system. The storage unit 110 stores all data collected, calculated, generated, and the like in the content illegal distribution countermeasure system. In the example illustrated in FIG. 1, the content 111 to be monitored, the keyword 112, the unauthorized content 113, the posting situation 114, the pseudo unauthorized content 115, and the browsing data 116 are stored.
The content 111 to be monitored is data for specifying the content that has received a request for monitoring from a customer. The content 111 to be monitored is, for example, a combination of a content name and a request reception number. Using the content 111 to be monitored as a main key, details of the request contents such as the name (company name) of the customer who is the requester, the request reception date, and the monitoring period can be searched in the log DB 130.
The keyword 112 is a keyword for searching through the Internet whether or not the content 111 to be monitored is posted on a content sharing site or the like. The keyword 112 is determined by extracting a word (person name, place name, etc.) frequently used in the content as an entity, or by adding a word characterizing the content by the client. When character data representing the content is included in the content or its attached file, it can be automatically extracted by the program.

The unauthorized content 113 is data for identifying the unauthorized content that is illegally distributed on the Internet as the content itself identified by the monitored content 111 or the modified content. The illegal content 113 is, for example, a combination of the name of the posted content, the posted URL (Uniform Resource Locator), and the detection date. The unauthorized content 113 is generated by the content monitoring unit 122. Using the unauthorized content 113 as a primary key, the log DB 130 can be searched for details of log information such as the deletion request date and the deletion date of the unauthorized content 113.
The posting status 114 is data on the posting status of unauthorized content. The posting status of the illegal content is generated by the content monitoring unit 122, and the posting status notifying unit 123 notifies the customer as the posting status 114. The posting status 114 is stored in the log database (DB) 130 by the log database management means 127. The posting status 114 includes a request reception number of the content corresponding to the unauthorized content (monitored content 111), a posted description of the unauthorized content, a site where the unauthorized content is posted, a detection date, and the like.
The pseudo illegal content 115 is a content that is similar in appearance only to the posted content and posted notation, and the content is different from the content specified by the illegal content 113, that is, dummy content. The posting notation is an item displayed on the content selection screen such as name, sample image (thumbnail image), file size, playback time, and the like. The pseudo illegal content 115 is generated by the pseudo illegal content generation means 124.
The browsing data 116 is data generated by the log database management unit 127 editing the log information stored in the log database 130. When the posting status browsing request is input from the user terminal of the customer or the content illegal distribution countermeasure system itself, the log database management unit 127 generates browsing data according to the content of the posting status browsing request and browses it in the storage unit 110. Store as data 116.

The calculation unit 120 is a calculation unit such as a CPU, a DSP, an accelerator, or the like in a computer system. The calculation unit 120 performs data calculation processing in the content illegal distribution countermeasure system. In the example shown in FIG. 1, the monitoring request receiving unit 121, the content monitoring unit 122, the posting status notification unit 123, the pseudo illegal content generation unit 124, the content distribution unit 125, the deletion request mail distribution unit 126, and the log database management unit 127. Arithmetic processing is performed.
The monitoring request receiving unit 121 receives a request from a customer for the content to be monitored. As a method of accepting a request, for example, there is a method in which an operator of a content illegal distribution countermeasure system that receives a request from a customer directly inputs necessary data to the content illegal distribution countermeasure system based on a request from a customer. . For example, there is a method in which a customer performs necessary data input from his / her user terminal to the content illegal distribution countermeasure system through the Internet. The difference between the former and the latter is technically a difference between direct input and input via the Internet. Since it is easy to infer one from the other, only the latter will be described here.
The monitoring request receiving unit 121 receives a request from a customer for the content to be monitored through a communication line such as the Internet. The content illegal distribution countermeasure system displays, as a web server, a home page of a service provider that provides a content illegal distribution countermeasure service on a client software browser provided in a user terminal (not shown) used by a customer. It has a function. Using the browser of the user terminal, the customer proceeds from the homepage to the member logon screen, request screen, content input screen for monitoring content, ordering screen, etc., and makes necessary input and services for the content desired to be monitored You can ask the provider. A keyword is also input on the content input screen. Customers can manually enter keywords from the keyboard. Further, it is possible to read a keyword file in which a plurality of keywords are recorded. Depending on the type of content, it can also be input by automatic extraction. The monitoring request reception means 121 performs processing on the content illegal distribution countermeasure system side for those inputs. Further, data related to monitored content requested by the customer and received by the monitoring request receiving unit 121 is stored in the storage unit 110 as the content 111 monitored by the monitoring request receiving unit 121, and the input keyword is stored as the keyword 112. Done. In addition, the log database management unit 127 uses the log database management unit 127 for a request reception number that is a number for identifying a request that is generated when a request is received as progress information during that time, a request reception date that is a date and time when the request is received, and the like. Log data is stored in the log DB).

The content monitoring unit 122 monitors the posting of unauthorized content on the Internet content sharing site based on the keyword. This unauthorized content is content that is identified by the monitored content 111 or content that has been illegally distributed on the Internet. The content monitoring unit 122 includes a search engine (program) for searching for content existing on the Internet based on keywords. When a content that can be regarded as an unauthorized content is detected, the unauthorized content 113 is generated as data specifying the content and stored in the storage unit 110. Whether or not the content can be regarded as illegal content is determined based on a specific determination condition with respect to the content detected by the search based on the keyword, and the extracted content is regarded as illegal content. can do. Here, the specific determination condition is, for example, confirmation that a digital watermark for protecting copyright is embedded in illegal content.
When the content monitoring unit 122 detects at least the posting of illegal content, the posting status notification unit 123 notifies the customer of the posting status 114, which is data on the posting status of illegal content generated by the content monitoring unit 122. As a form of notification, a form in which details are notified by e-mail (e-mail), or an outline is notified by e-mail, and details are referred to browsing data 116 (web page) is applied.

The pseudo illegal content generating means 124 generates the pseudo illegal content 115 having the same content as the illegal content on which only the appearance such as the posted notation is posted, but different in content from the illegal content. The pseudo illegal content generation unit 124 sets the pseudo illegal content 115 so that the items displayed on the content selection screen such as the name, sample image (thumbnail image), file size, reproduction time, etc. are posted in the same manner as the illegal content. Generate. On the other hand, the pseudo fraudulent content 115 is generated assuming that the contents and contents are completely meaningless, or have no legal, ethical or other problems.
The content distribution unit 125 distributes the pseudo illegal content 124 generated by the pseudo illegal content generation unit 124 to a plurality of content sharing sites on the Internet, in the example shown in FIG. 1, the content sharing site A 210, the content sharing site B 220, and the content sharing site C 230. To do.

The deletion request mail distribution means 126 automatically distributes an illegal content deletion request mail to a person who operates a site on which illegal content is posted. Of course, information (not shown) such as a mail destination related to a person who operates a content sharing site or the like is registered in the storage unit 110 in advance.
The log database management unit 127 generates a request reception number that is generated as a number for identifying the request when the monitoring request reception unit 121 receives the request, a request reception date and time that is the date and time when the request is received, and the content monitoring unit 122 is illegal. From the detection date that is the date when the content is detected, the deletion request date when the deletion request mail delivery unit 126 makes a deletion request, and the deletion date that is the date when the content monitoring unit 122 no longer detects unauthorized content, a request is made. At least two including the reception number are linked and stored in the log database (DB) 130. Further, the log database management unit 127 saves in the log database (DB) 130 according to the contents of the posting status browsing request when there is an input of the posting status browsing request from the user terminal of the customer or the content illegal distribution countermeasure system itself. The log information thus edited is edited to generate browsing data, which is stored as browsing data 116 in the storage unit 110.
The log database (DB) 130 is a database managed by the log database management unit 127. The log database (DB) 130 stores log information in the content illegal distribution countermeasure system.
According to the log database management means 127 and the log database (DB) 130, the progress status from the reception of a request from a customer to the deletion of illegal content and other information can be obtained by searching the log DB for the monitored content.

The configuration has been described above. Next, the operation in the content illegal distribution countermeasure system of the present invention will be described. An example of the operation in the content illegal distribution countermeasure system of the present invention is shown in FIG.
First, in step S11 (requested in advance) in FIG. 2, a content holder who is a copyright holder for the content, a content holder as an organization, or an agent thereof, that is, a customer, monitors unauthorized distribution of the content. To make a request. When this request is made from the user terminal via the Internet, as described above, the monitoring request receiving unit 121 receives a request from a customer for the content to be monitored through a communication line such as the Internet. Further, the operator of the content illegal distribution countermeasure system can input the contents of the request of the customer in the content illegal distribution countermeasure system. At that time, the monitoring request accepting means 121 can accept the request by inputting the contents of the request.
Next, in step S12 (always NW monitoring automation), the content monitoring unit 122 monitors the posting of illegal content on the Internet content sharing site based on the keyword. This monitoring is always performed. As shown in FIG. 2, the content is illegally uploaded to a content sharing site A 210, a content sharing site B 220, a content sharing site C 230, a file cocan service, a summary site, a bulletin board, etc. by a malicious user. A general user can access those sites through the Internet and download illegal contents.
Next, in step S13 (contact), the posting status notifying unit 123, when the content monitoring unit 122 detects at least the posting of illegal content, is a posting status that is data on the posting status of illegal content generated by the content monitoring unit 122. 114 is notified to the customer. For example, mail (electronic mail) is used as the notification form. Of course, when the posting situation 114 is generated, the operator of the content illegal distribution countermeasure system can notify the customer of the posting situation 114 by telephone, sealed letter, or the like.
