DESCRIPTION OF THE PREFERRED EMBODIMENTS An apparatus and a method according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram of a homepage management device according to an embodiment of the present invention. This device is built into the facilities of an Internet service provider (ISP). The ISP provides a homepage server 1 so that the homepage of each creator can be browsed on the Internet 8. An access control device 2 is provided between the homepage server 1 and the Internet 8, and transmits a request from an Internet user to the server 1 and transmits a response from the server 1 to the Internet 8. The access control device 2 includes an access restriction list (memory) 2
a to restrict requests through the Internet based on this list. For example, access restriction list 2
It is assumed that a contains URLs of some of these homepages among many homepages of the homepage server 1. When an access is made to these URLs, the access control device 2 rejects the access,
Or limit the number of accesses. By managing the access restriction list 2a, the administrator of the ISP can restrict access to a homepage that is not suitable for disclosure among homepages provided by the homepage server 1.

Reference numeral 3 denotes a URL (Uniform Resource Locator) pointing to a home page in the home page server 1.
It is an access number measuring unit that measures the number of accesses for each. Reference numeral 4 denotes a popular URL extraction unit that creates a URL list in which the number of accesses equal to or greater than a predetermined number is measured based on the measurement result of the access number measurement unit.

Reference numeral 5 denotes a correlation detecting unit that calculates the correlation value by comparing the content of the URL described in the URL list created by the popular URL extracting unit with a matching database. The correlation detecting unit 5 is a pattern information extracting unit 5 for extracting pattern information displayed on an image included in the homepage.
a, a character information extracting unit 5b for extracting character information displayed on the image, and a text information extracting unit 5c for extracting text information included in the homepage.

The outputs of the extraction units 5a to 5c are collated with the contents of the collation database 6, and a correlation value is obtained.
This correlation value indicates how much the extracted content (data) matches the content of the database 6.

For example, the color scheme of one or a plurality of colors is compared with the ratio of the area of each color to the pattern. If the color scheme and the area ratio match, the correlation value is high, and if any one of them matches, the correlation value is medium. If the two values do not match, the correlation value is low. As an example, in an image of a naked human body, a flesh color region is the largest, and a hair color (black, gold, etc.) region is always included. Other colors (blue in the sky, green in the forest, etc.) are considered background, and this area is smaller than the skin color area. Pattern data is created from such a viewpoint. As another example, a trademark, a trade name, a symbol mark, and an animation character are used as pattern data, and the pattern data is compared with the extracted pattern. A known method (for example, a method using a cross-correlation function) can be applied as a method of obtaining a correlation value between patterns.

On the other hand, for characters, the extracted characters (text) are compared with the text in the database.
The greater the number of matching characters, the higher the correlation value. For example,
If the extracted characters and the text of the database completely match, the correlation value is 100%. For example, if 5 characters out of 10 characters match, the correlation value is 50%.

A known character recognition method can be applied to the process of extracting characters from an image by the character information extracting unit 5b.

Reference numeral 7 denotes a prohibited address for defining a URL exceeding a predetermined correlation value in the correlation value list output from the correlation detection unit as a prohibited address, and adding the prohibited address to the access restriction list. The generation unit.

FIG. 5 shows an example of the collation database 6.
The matching database 6 includes image pattern data for matching images and text pattern data for matching text. The text pattern data includes information related to copyright such as a performer name, a lyric / composer name, and a song title.The text pattern data includes information that is against public order and morals. Data includes copyright information such as CD jackets and book covers. Thereby, the correlation detecting unit 5
It can detect that a website creator uses a copyrighted work of another person or uses words that are against public order and morals. By the correlation detection unit 5 and the collation database 6,
Homepage can be evaluated.

FIG. 2 is a flowchart showing a processing procedure of the apparatus according to the embodiment of the present invention. The number of accesses is measured for each URL (S1). It is determined whether or not the number of accesses exceeds the threshold (S2).
L is added to the popular URL list (S3). S1 to S3
The reason why some URLs are extracted from all the URLs is to reduce the monitoring load on the device. The number of homepages in the server managed by the ISP is enormous, and monitoring all of them is not practical in terms of the processing capacity of the device. Therefore, some URLs are extracted and the extracted U
RL is monitored. Here, the number of accesses, that is, popularity, is used as the extraction criterion. Even if you publish problematic content on a website, the impact is limited if the number of accesses is small. On the other hand, in the case of a homepage with a large number of accesses, its influence cannot be ignored. From such a viewpoint, the URL is determined based on the number of accesses.
It is desirable to extract Another reason is that monitoring the number of accesses is technically easy. When the number of accesses suddenly increases, there is a possibility that some special event has occurred. Therefore, the rate of increase in the number of accesses may be monitored. When the rate of increase in the number of accesses is remarkable, monitoring may be performed with emphasis. S1 to S3
Is executed for all the URLs (S4, S4
5).

Next, the extracted URL (popular URL) is evaluated. The content of the popular URL list is collated with the collation database to calculate a correlation value (S6). This detailed processing will be described later. It is determined whether or not the correlation value exceeds the threshold value (S7), and if so, the URL is defined as a prohibited address and added to the access restriction list (S7).
8). The processing of S6 to S8 is executed for all URLs (S9, S10).

FIG. 3 is a flowchart of the procedure for calculating the correlation value. Read the target homepage (S1
1) Separating a text and an image, which are contents contained therein, (S12). The text data is directly collated with the text pattern data, and the correlation value is calculated (S16). The image data is reproduced as an image (S1
3) Character information included in the image is extracted therefrom (S14). A known character recognition algorithm can be used as the process of S14. The extracted character information is collated with the text pattern data, and a correlation value is calculated (S16).

A pattern contained in the image is extracted from the image data (S15). A known pattern extraction algorithm can be used as the processing of S15. For example, when the image includes characters of trademark, trade name, symbol mark, and animation, these are extracted in S15. The extracted marks etc. are
The data is collated with the data (S17). If these match, there is a high possibility that the trademark, trade name, symbol mark, and character are used on the homepage. If used without permission, it may violate trademark law and copyright law, and the ISP administrator should pay attention to the homepage. For example, the image data includes a trademark, a trade name, a symbol mark, and an animated character as image pattern data, and the pattern data is compared with the extracted pattern. A known method (for example, a method using a cross-correlation function) can be applied as a method of obtaining a correlation value between patterns.

As a method of collating the image pattern data in S17, the image pattern data of the collation database is provided with information on one or a plurality of predetermined colors and the size of an area displayed by the colors. Alternatively, a region that matches the predetermined color may be obtained from among the images included in the contents of the URL, and the ratio may be output as a correlation value. For example, for a pattern, a comparison is made between the color scheme of one or more colors and the area ratio of each color.If the color scheme and the area ratio match, the correlation value is high, and if any one of them matches, the correlation value is moderate. If the two values do not match, the correlation value is low. As an example, in an image of a naked human body, a flesh color region is the largest, and a hair color (black, gold, etc.) region is always included. Other colors (blue in the sky, green in the forest, etc.) are considered background, and this area is smaller than the skin color area.

The processing of FIGS. 2 and 3 may be repeated several times. FIG. 4 shows a flowchart in this case. A threshold value of the number of accesses is set (S20), a threshold value of the correlation value is set (S21), and the homepage is evaluated according to the procedure of FIGS. 2 and 3 (S22), and a problematic homepage is extracted ( (S23), the extracted homepage is added to the monitoring target list (S24). In FIG. 2, the extracted URL is immediately added to the access restriction list 2a as a prohibited address, but in FIG. 4, it is added to the monitoring target list. Immediately prohibiting access to the extracted URL is desirable in that it will not allow external Internet users to browse problematic content, but on the other hand,
This impairs the rights of the contractor of the server 1. The UR
A complaint may come from the producer of L. Further, just because the URL is extracted by the device / method according to the embodiment of the present invention, it cannot be concluded that the URL is really harmful. Therefore, for the time being, only the extracted URL is added to the monitoring target list, and the administrator continuously monitors the URL, and the ISP administrator refers to the opinion of the general user with respect to the URL. It is desirable to make a final conclusion. Waiting for this conclusion, the UR
L may be added to the access restriction list.

From such a viewpoint, FIG.
After 24, processing for making a recommendation for correction, deletion, or abolition of a problematic homepage (S26), and subsequent monitoring (S27) are provided. The notification in S26 can be made by e-mail. The monitoring in S27 can be performed not only by the administrator himself, but also by the apparatus and method according to the embodiment of the present invention.

On the other hand, after the process of S24, the threshold value of the number of accesses may be lowered (S25), and the processes of S20 to S24 may be repeated. This is because the homepage changes from time to time and requires continuous monitoring, and it also reduces the monitoring burden. To further explain the latter, if the apparatus / method according to the embodiment of the present invention is first applied to a server providing a large number of homepages, a very large number of problematic homepages may be extracted in some cases. . In this case, the monitoring burden on the administrator becomes excessive. Therefore, at first, only extremely popular homepages are targeted. As described above, it is effective even if the target is limited in this way. If this process is repeated and there is no problem with the popular homepage, the threshold is sequentially reduced and the target is expanded. Then, the above processing is repeated. Therefore, according to the processing of FIG. 4, it is possible to gradually widen the monitoring target and finally evaluate all the homepages while suppressing the monitoring burden on the administrator.

In addition to adding the URL evaluation result to the access restriction list, the access restriction list may be made public. The ISP can evaluate the homepage extracted from the viewpoint of a general user and manage it by reflecting the result. By publishing the list, it can be expected that the creator of the homepage will voluntarily correct the content to an appropriate one.

The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the invention described in the appended claims, which are also included in the scope of the present invention. Needless to say, this is done.

In this specification, means does not necessarily mean physical means, but also includes a case where the function of each means is realized by software.
Further, the function of one unit may be realized by two or more physical units, or the function of two or more units may be realized by one physical unit.

[0044]

According to the present invention, it is possible to autonomously and spontaneously extract pages that are offensive to public order and morals from the homepages managed by the ISP, and take measures to stop the publication. Web sites can be provided without lowering prices.
