DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a WWW browser display page control method and method , and more particularly to a WWW browser for browsing HTML data on the Internet.

[0002]

2. Description of the Related Art Conventional WWW (World Wide Web)
The browser is an HTML (HyperText Markup Language) of a specified page on the Internet (Internet).
e; hypertext markup language) data. HTML is used when composing text for WWW, and is composed of two parts, a header and a body, and is described using a code called “tag”.

[0003]

The WWW browser can access HTML data around the world.
In some data, for example, information data harmful to adolescents is included, and the WWW browser has a problem that these harmful pages can be easily accessed by adolescents. .

[0004] The reason is that this WWW browser has only a function of unconditionally displaying designated HTML data.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made in view of the above problems, and an object of the present invention is to provide a method and a method capable of restricting the display of pages harmful to young people, for example, in a WWW browser. To provide.

[0006]

According to the present invention, there is provided a method for controlling a display page in a WWW browser according to the present invention.
The method extracts text data in the HTML data of a display page, compares the text data with a set keyword, and notifies the WWW browser of an error when there is text data that matches the keyword. And restricting the display.

In the present invention, preferably, before the HTML data of the contents of the page is displayed on the WWW browser, a means for hooking the HTML data and extracting the text data and, for example, defining a keyword deemed to be harmful in advance are defined. Means for comparing the text data in the hooked HTML data with the defined keyword, and means for notifying the WWW browser of an error when there is data matching the keyword. In this case, a means for notifying the hooked HTML data to the WWW browser is provided.

As described above, according to the present invention, even if the means for hooking the HTML data monitors the contents of the HTML data and the user designates a page with a WWW browser, for example, a keyword which is considered unfavorable for adolescents is The included HTML data is not displayed.

[0009]

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a diagram for explaining an embodiment of the present invention, wherein an IP server 2 for providing HTML data is provided.
0 and WWW browser 11 for displaying HTML data
FIG. 2 is a diagram showing a relationship between the display page control method (system) 12 and a display page control method (system) 12.

The IP server 20 performs a connection service with the Internet, which is usually called an “Internet provider (IP)”. A personal computer (also referred to as a “PC”) 10
Connect by Ethernet or modem, etc.
Get HTML data.

Referring to FIG. 1, in the conventional system, P
On the C10, the software of the WWW browser 11 operates, and a page that the user wants to acquire from the WWW browser 11 is transmitted to the IP server 20 ().
The designated HTML data is returned to the WWW browser 11 (), and the WWW browser displays the contents.

In the embodiment of the present invention, the display page control system 12 operates on the PC 10 and is interposed between the WWW browser 11 and the IP server 20.

The display page control system 12 directly transmits HTML data from the IP server 20 to the WWW browser 11.
Without passing it to the server, once receive () itself, analyze the contents of the HTML data received from the IP server 20, and check whether any harmful data is included. As a result, there is no problem. If HTML data is WW
Handed over to W browser 11 (), WWW browser 11 is H
Displays the contents of TML data. On the other hand, if there is a problem as a result of the check, the display page control system 12
An error indicating that there is no page specified is returned to the WW browser 11.

In the embodiment of the present invention, as shown in FIG. 1, the display page control system 12 has a method of interposing between the WWW browser 11 and the server 20,
The system may be added to the WWW browser 11 itself.

In the case of realizing a system interposed between the WWW server 11 and the IP server 20, it is easily possible by setting a proxy (a function for taking in data not through the server but through another). Note that this method itself is not directly related to the subject of the present invention, and thus the details thereof are omitted.

FIG. 2 is a flowchart for explaining the operation of the embodiment of the present invention. The operation of the display page control system according to the embodiment of the present invention will be described with reference to FIG.

When the display page control system 12 is started on the PC 10, it intervenes between the IP server 20 and the WWW browser 12, hooks the HTML data sent from the server 20, as shown in FIG. Is extracted (step S11).

Also, keywords for restricting display pages are defined in advance, and these keywords are stored in a predetermined storage unit (step S12).

Then, the text data of the HTML data is compared with the keyword (step S13). If there is text data that matches the keyword, an error is notified to the WWW browser 11 (step S15). If the keyword does not match, the HTML data is notified to the WWW browser 11 (step S1).

DESCRIPTION OF THE PREFERRED EMBODIMENTS In order to explain the above-mentioned embodiment of the present invention in more detail, an embodiment will be described below with reference to a specific example. FIG. 3 is a diagram showing a configuration of one embodiment of the present invention.
FIG. 4 is a flowchart for explaining the operation of one embodiment of the present invention. FIG. 4A shows an example in which an error is notified to the WWW browser of the page and the display is restricted, and FIG. 4B shows an example in which the page is displayed as it is.

Here, the Internet provider (I
P), a mesh (NEC Internet connection service) 101, and a WWW browser, Netscape
(However, “Netscape” is a registered trademark) .

[0023] Before starting the Netscape1 0 2,
The user activates the page display control system 103 of the WWW browser according to the present invention, and sets “HOOKHTML” as a mesh and a unique server name for the Internet provider to be connected. Further, for example, “sex” is set as a keyword for controlling the display of the page.

Next, start the Netscape1 0 2,
The server name to be connected is set to “HOOKHTML” (see 104 in FIG. 3).

Here, when the user enters Netscape 10 2
It is assumed that “www.adult.co.jp/” is designated for a URL (Uniform Resource Locator; page designation) which is a standard for identifying a file on the WWW (FIG. 4A). .

[0026] Netscape1 0 2, the server "HO
OKHTML "for the specified page (Fig. 4 (A)
of).

Here, "HOOKHTML" is the display page control system 103, and requests the designated page to the mesh 101 (FIG. 4A).

When the specified page is found, the mesh 101 returns HTML data to the display page control system 103 (FIG. 4A).

It is assumed that the contents of the HTML data are as shown in FIG. HTML document is <htm
l> tag and end with </ html> tag, <he
<ti> between the <ad> tag and the </ head> tag.
The title is written between the <tle> tag and the </ title> tag. The body is <body> tag and </ body
y> tag. In addition, in addition to specifying the character size in the text, the hypertext ring destination is <a hr
f = “link destination file”>.

In this embodiment, the HTM shown in FIG.
The screen control information enclosed by <> (tag) is deleted from the L data (document), and only the text information as shown in FIG. 6 is extracted.

Next, the present embodiment compares the text information with the keyword.

In the case of this example, since the keyword “sex” matches the text data, Netscape 10
2 is notified that there is no designated page (FIG. 4
-), Netscape 102 displays an error (FIG. 4A).

On the other hand, if the keyword is "Japan", the keyword does not match.
The content is passed to etscape as it is, and the content is displayed (see FIG. 4B).

[0034]

As described above, according to the present invention,
For example, by configuring the display of HTML data containing data (keywords) judged to be harmful when viewed by adolescents in advance, the adolescent can browse harmful pages using a WWW browser. The effect that it can prevent is produced.
