[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a filtering management method for managing a filtering device that restricts the display of Web pages containing harmful information distributed on the Internet, and a filtering management program for causing a computer to execute the management method.
[0002]
[Prior art]
Anyone can provide information on the Internet. For the information distributed on the Internet, there is only the principle of selecting at your own risk, and the responsibility is not clear. For this reason, information that contributes to people's knowledge development and information that is highly illegal or that is considered harmful are distributed in a mixed manner, which is a problem in using the Internet. In particular, it is a social problem when minors such as children and students use the Internet.
[0003]
Therefore, there is a demand for a technology that can accurately limit the browsing of highly illegal information or information that is generally considered harmful (hereinafter referred to as harmful information).
[0004]
In the prior art, in order to restrict browsing of harmful information, a filtering device that restricts display of a specific Web page is installed between information on the Internet and users of the Internet.
[0005]
In general, when a filtering device determines that an accessed web page is harmful based on a predetermined rule, the filtering device prohibits the user from browsing harmful information by prohibiting the display of the web page. ing.
[0006]
There are the following methods for prohibiting the display of Web pages.
[0007]
1) Prohibition of display using a list of harmful words
For example, words and phrases that are supposed to represent harmful information included in the Web page, such as “prohibition of browsing under 18 years old” and “murder”, are registered in the harmful phrase list. Then, the filtering device searches the words and phrases of the Web page designated by the user as the access destination, and when it is determined that the words and phrases registered in the harmful phrase list appear at a certain frequency, The web page is considered to contain harmful information and display of the web page is prohibited.
[0008]
2) Display prohibition using harmful content URL list
The URL (Uniform Resource Locator) and address of a Web page evaluated as having harmful information posted are registered in the harmful content URL list. When the filtering device determines that the URL or address of the Web page specified by the user as the access destination is registered in a harmful content URL list, that is, a so-called black list, the filtering device identifies the Web page as harmful information. And the display of the Web page is prohibited.
[0009]
3) Prohibition of display using rating nonconforming page information
For example, a system is used in which the creator of a web page self-reports the nature of the web page using a rating standard provided by PICS (Platform for Internet Content Selection) that is being introduced by the Electronic Network Council.
[0010]
That is, the Web page creator assigns PICS rating information to the HTML using a rating tag, and gives information indicating that the Web page is incompatible with a specific person such as a minor. . When the filtering device detects corresponding rating information (nonconformity) in the HTML of the Web page designated as the access destination by the user, the filtering device regards the Web page as harmful information and prohibits the display of the Web page. To do.
[0011]
4) Display permission using excellent content URL list
For example, a sex education page for children, etc., which includes words and phrases registered in the harmful phrase list of 1) and is usually judged to be prohibited from display, but is not classified as harmful information The URL (Uniform Resource Locator) and address of the Web page evaluated as having information posted are registered in the excellent content URL list. If the URL or address of the Web page specified by the user as the access destination is registered in the excellent content URL list, so-called white list, the filtering device regards the Web page as excellent and Web page display is allowed.
[0012]
[Problems to be solved by the invention]
However, in the method of prohibiting display using the harmful phrase list in 1), for example, “dead” can be expressed as “four”, so that the phrase search can be avoided. It is not possible to prohibit the display of Web pages that contain harmful information. Also, it is impossible to check whether image data or audio data other than text format is harmful information.
[0013]
In addition, in the display prohibition method using the harmful content URL list of 2), an expert such as a teacher or a lawyer evaluates and examines the harmfulness of the content of the Web page and registers it in the list. In the present situation where a large number of web pages are registered every day, new web pages must be constantly evaluated, resulting in a heavy workload. In addition, a Web page including harmful information is displayed until it is registered in the harmful content URL list. For this reason, such a method, which must rely on the hand of a specific minority, is reliable but not efficient.
[0014]
Further, the display prohibition method using the non-conforming page information of the above 3) is a self-regulation based on the self-declaration of the Web page creator in principle, and therefore lacks reliability. In addition, although the viewer can evaluate the contents of the Web page and change the rating information, the Web page including harmful information is displayed until the rating is changed, as in 2).
[0015]
In the current situation where a specific person evaluates a Web page, which is a criterion for prohibiting display, as in the conventional method, the burden of the evaluation work is increasing. In addition, since a huge amount of Web pages exist on the Internet, it is inefficient to perform the evaluation only by a specific person who is contracted or entrusted.
[0016]
The present invention is intended to solve such a problem, and the object of the present invention is to efficiently collect evaluation criteria used for determining whether or not to prohibit the display of a Web page and to delete harmful information on the Internet. It is to provide a filtering management method capable of accurately prohibiting the display of information.
[0017]
Another object of the present invention is to provide a program for executing such filtering management method on a computer.
[0018]
[Means for Solving the Problems]
In order to achieve the above object, the present invention not only enables a filtering service provider to unilaterally collect and distribute a filtering definition as a criterion for determining whether to prohibit Web page display by a filtering device to a filtering device. Thus, a filtering management method capable of feeding back update information of a distributed filtering definition from a user of a filtering device to a server that manages filtering is realized.
[0019]

[0021]
Furthermore, the filtering management method of the present invention specifies at least the reception date and time and the filtering device that is the transmission destination of the update information when the update information is received from the one filtering device. The information processing log information including the information to be output is provided.
[0022]
Moreover, this invention is a filtering management program for making a computer perform the step which implement | achieves the filtering management method provided with the said process.

[0024]
Further, the present invention is a filtering management program for a filtering device for causing a computer to execute the step of realizing the filtering management method by the filtering device.
[0025]
The present invention operates as follows. That is, the filtering management server distributes the filtering definition to the filtering device in advance. When a user browses a web page on the Internet using a filtering device using the filtering definition and evaluates that the browsed web page is harmful, for example, the URL of the web page is defined as a filtering definition. Update the filtering definition by adding to. Then, the difference information of the updated filtering definition is transmitted to the filtering management server together with its own signature. Then, the filtering management server reflects the update information in the filtering definition of the filtering definition storage unit, and further transmits the update information of the filtering definition to another filtering device.
[0026]
In addition, when update information is received from the filtering device, the filtering management server can acquire information provision log information such as reception date and time and information for specifying the transmission source filtering device and use it for an incentive for information provision. To. For example, the information provision log information can be output, and the usage fee of the filtering system, the redistribution fee of the update information of the filtering definition, etc. are reduced based on the information provision log information.
[0027]
Thus, only a small number of specific persons evaluate the Web page and update the filtering definition, but each user of the filtering device can continue to update the filtering definition. For this reason, the update information of the filtering definition is quickly collected from a wide range.
[0028]
Furthermore, since the updated information of the filtering definition is immediately redistributed from the filtering management server to another filtering device, the filtering device can accurately determine the Web page.
[0029]
Note that a program for causing a computer to execute the processing steps of the present invention can be stored in an appropriate recording medium such as a portable medium memory, a semiconductor memory, or a hard disk that can be read by the computer. Or provided by transmission / reception using various communication networks via a communication interface.

[0047]
The harmful word / phrase list 161 is a list for storing words or phrases that are supposed to represent harmful information. The harmful content URL list 162 is a list for storing URLs and addresses of Web pages evaluated as harmful. The rating nonconforming page information list 163 is, for example, a list that stores tag information corresponding to the rating of nonconforming browsing set by the rating standard provided by the PICS. The excellent content URL list 164 includes words and phrases included in the harmful word list 161 and is normally determined as a display prohibition target, but URLs of Web pages evaluated as not harmful in content A list for storing addresses. Each list in the filtering definition DB 16 may be a list similar to that used in conventional filtering.
[0048]
The support target person DB 17 is a database that stores and manages the support target person terminal 3 that is a distribution destination of the filtering definition update information when the filtering definition DB 16 is updated.
[0049]
FIG. 4 shows a data configuration example of the support target person DB 17. The support target person DB 17 is a data record whose items are a contractor ID that is information for uniquely identifying the support target person terminal 3, a contract period T thereof, and a group Gr to which the support target person (contractor) belongs. 140 is stored. As the belonging group Gr, groups such as elementary school teachers, junior high school teachers, and parents with children are set by the same grouping as the belonging group Gr stored in the data record 140 of the information provider DB 14.
[0050]
The filtering device 20 of the information provider terminal 2 includes a filtering definition update unit 21, a filtering definition transmission unit 22, and a filtering definition storage unit 23.
[0051]
The filtering definition updating unit 21 is a unit that updates the contents of the filtering definition storage unit 23 based on data input by the user.
[0052]
The filtering definition transmission means 22 gives information (contractor ID) indicating its own information provider terminal 2 to the filtering definition update information related to the update processing performed by the filtering definition update means 21 and transmits it to the filtering management server 1 It is.
[0053]
The filtering definition storage unit 23 is a storage unit that stores a filtering definition (file) that is determination criterion data used for filtering in the filtering device 20. The content of the filtering definition is the same as the data related to the group Gr to which the user of the information provider terminal 2 belongs in the filtering definition 160 of the filtering definition DB 16.
[0054]

[0058]
FIG. 5 shows a processing flow of the present invention.
[0059]
In the filtering device 20 of the information provider terminal 2, the filtering definition updating unit 21 updates the filtering definition stored in the filtering definition storage unit 23 based on the user input data as in the conventional case (step S11). After the update is completed, the filtering definition transmission unit 22 assigns the contractor ID of the information provider terminal 2 to the filtering definition update information related to the update process, and transmits it to the filtering management server 1 (step S12).
[0060]
In the filtering management server 1, the filtering definition receiving means 11 receives the filtering definition update information with the contractor ID (step S21). Further, it is confirmed whether or not the contractor ID is registered with reference to the information provider DB 14 (step S22). If the contractor ID matches the data record 140 of the information provider DB 14, the belonging group Gr associated with the contractor ID is extracted, and the extracted belonging group Gr and filtering definition update information are filtered. The data is transferred to the DB update unit 12. Further, the filtering definition receiving unit 11 stores information provision log information such as the reception date and time, the contractor ID of the transmission source, and the transmitted filtering definition update information in the information provision log information DB 15 as a reception processing log (step S23). ).
[0061]
The filtering DB update unit 12 updates the filtering definition DB 16 by reflecting the filtering definition update information in the filtering definition 160 corresponding to the received group Gr (Step S23).
[0062]
Then, when the filtering definition DB 16 is updated, the update information transmission unit 13 refers to the data record 170 of the support target person DB 17 and extracts the contractor ID of the support target person terminal 3 belonging to the updated affiliation group Gr. (Step S24). Then, the update information transmitting unit 13 transmits the filtering definition update information related to the update to the support target person terminal 3 based on the extracted contractor ID (step S25).
[0063]
The update information receiving means 32 of the support target person terminal 3 receives the filtering definition update information received from the filtering management server 1 (step S31), and the filtering definition updating means 31 performs the filtering definition based on the received filtering definition update information. The filtering definition in the storage means 33 is updated (step S32).
[0064]
In this way, the filtering definition updated at the information provider terminal 2 of the user who receives the provision of the filtering service and who concludes the information provision contract is used in many other ways via the filtering management server 1. Distributed to the support target person's terminal 3. As a result, the number of persons who can update the filtering definition increases, and the opportunity for the update process increases.
[0065]
Also, users are grouped and filtering definition update information is distributed to each group. As a result, the update status of the filtering definition differs for each group, and a harmful determination criterion customized for each group is formed, thereby enabling filtering suitable for the characteristics of the group.
[0066]
It is assumed that the filtering definition update information transmitted from the information provider terminal 2 has contents that should be reflected in the filtering definitions of all the belonging groups. In this case, the administrator of the filtering management server 1 verifies the filtering definition update information stored in the information provision log information DB 15 or the filtering definition 160 of the filtering definition DB 16 for every predetermined opportunity or period, and all the belonging groups When it is determined that the update information should be updated to the filtering definition, the administrator performs the update process manually.
[0067]
Further, the information provision log information stored and managed in the information provision log information DB 15 is appropriately referred to when calculating the support consideration such as the usage fee of the filtering device, and is reflected in the amount of a predetermined normal charge. This provides an incentive to feed back the filtering definition update information from the user to the filtering management server 1.
[0068]
As mentioned above, although this invention was demonstrated by the embodiment, it cannot be overemphasized that a various deformation | transformation is possible for this invention in the range of the main point. For example, when transmitting the filtering definition update information, the filtering definition transmission means 22 may encrypt the information to be transmitted and transmit it.
[0069]
【The invention's effect】
As described above, according to the present invention, the filtering definition update information is fed back to the filtering management server widely and in large quantities from a person who is a filtering device user and who has signed an information provision contract, not a specific minority. To be. This reduces the burden of collecting harmful information on the Internet on the filtering management server side. In addition, the opportunity for updating the filtering definition is increased, and more rapid update can be realized.
[0070]
Moreover, according to this invention, a filtering management server transmits to the filtering apparatus of the support subject person terminal which belongs to the same group as the information provider terminal which produced | generated the update information of filtering definition. Thereby, the filtering definition according to the characteristic of a group comes to be formed, and it becomes possible for the filtering apparatus to perform more exact filtering.
