Since only homepages registered in advance in SP3A can be viewed, viewing of other homepages including homepages that provide harmful content information can be completely eliminated.

One or more specific ISPs 3A also exist, each of which can be connected to the Internet 5 (FIG. 1).
For convenience, only one special ISP 3A is shown). In addition to the above-described configuration of the special ISP 3B, the browsable home pages are divided into groups based on predetermined conditions, and a browsable group is further designated based on the ID input from the client 1. I have. That is, IDs are issued separately for adults, minors, schools, and the like. For example, if the user is an adult, I
The first letter of D starts with "A" and becomes "A0001"
If the user is a minor, the first letter of the ID is "B"
And "B0001" when the user is a school, and the first character of the ID is "C0001" starting with "C". In this case, it is also possible to issue an ID only to adults, and to refuse to issue an ID to minors and schools.

On the other hand, in the specific ISP 3A, the browseable home pages are divided into groups A, B, and C, and the address information is recorded in the storage device 35A for each group. For example, in the "Group A", address information of homepages (adult designation, etc.) that only adults can view is collected. In the "Group B", address information of homepages (TV cartoons, etc.) that can be viewed by minors are collected. In the "C group", address information of homepages (such as those related to education) that can be browsed at schools is collected. Then, a person having an adult ID whose ID starts with "A" can access and browse the homepages belonging to any of the groups A to C, and enter a minor ID whose ID starts with "B". Those who have access to the homepage belonging to either of the group B and the group C can be browsed, but cannot browse the homepage belonging to the group A, the school ID whose ID starts with "C" Are allowed to access the homepage belonging to the group C and only to browse the homepage. In addition, specific IS

If the D unit is disconnected from the connection terminal 18, the restriction will be applied again. The ID unit may not be issued to minors. The ID unit 20 can be a mobile phone ID unit by recording the data in a memory of the mobile phone. Since it is necessary to clarify the identity of the mobile phone at the time of purchase, the ID can be obtained by this.

The registration of the address information of the browseable homepage in the specific ISP 3A and the special ISP 3B is performed by registering the address information of the browsed homepage in the address information database 4a of the management server 2 which integrally manages the address information. The management server 4, like the authentication server 2 and the client 1, is constituted by a normal computer having a central processing unit, a communication control unit, a storage device, an input unit, and a display unit, and a description thereof will be omitted. I do. The management server 4 is connected to each of the specific ISPs 3A and the special ISPs 3B by the communication line 9, and stores the address information that can be browsed into the specific ISPs 3A and the special ISPs 3A.
B has an address information registration unit that transmits the information to the B through the communication line 9 and sequentially updates the address information registered in the specific ISP 3A and special ISP 3B. The address information registration unit updates the address information recorded in the specific ISP 3A and the special ISP 3B by rewriting or adding the address information.

Next, the homepage browsing method according to the present invention will be described in detail together with the operation of the above-described homepage browsing system. First, specific ISP3A and special IS
In response to the request of the person who wishes to register the address information in P, the contents of the homepage to be browsed are checked in advance, and if it is judged to be inappropriate, the registration is refused, and if the registration is approved, The home pages are divided into predetermined groups according to the contents of the home pages, and the address information of the home pages belonging to each group is recorded in the storage device 35A of the specific ISP 3A. In addition, the storage device 35B for the special ISP 3B records address information of a homepage that the special ISP 3B permits to browse.

On the other hand, as shown in FIG. 6, a user who wishes to view a home page based on the present system has an ID for enabling connection to a specific ISP 3A and / or a special ISP 3B to a secretariat managing the system. Request issuance of a password (step S11). If the user wants the ID unit 20, the secretariat sets the ID unit 2
0 The purchase certificate is issued, and the user himself purchases it separately at the agency based on the certificate (step S12). In this case, a mobile phone ID unit may be desired. On the other hand, if the user does not wish to purchase the ID unit 20, a separate ID and password are issued (step S13). When the secretariat issues the ID and the password, it is registered in the authentication server 2 (step S14). Thus, the setting of the ID and the password is completed.

The client 1 is limited to a specific ISP 3A and / or a special ISP 3B in advance in connection with ISPs. When communication software and a browser are started to connect to the Internet 5, first, an authentication server is connected via a communication line 9. 2 (step 21). When an ID unit 20 (or a mobile phone ID unit) is attached to the connection terminal 18 of the client 1, the ID is sent from the memory of the ID unit 20 to the authentication server 2. Is input to request authentication. If the ID unit 20 is not attached to the connection terminal 18 of the client 1, an ID and a password are input from the input unit 17 and sent to the authentication server 2 to request authentication (step S22).

Next, as shown in FIG. 7, based on an account for connecting to the authentication server 2, an ID and a password sent from the client 1 requesting connection to the Internet via the communication line 9 are registered in advance. If the ID and the password match, the connection to the specific ISP 3A is relayed (step S23). If the ID and password do not match the ID and password registered in advance (ID
Special ISP3B)
Is relayed (step S24). Special ISP
3B, only the home page having the address information recorded in the storage device 35B of the special ISP 3B can be browsed (step S2).
5) If the user enters another URL from the browser, the user is not connected to the homepage and cannot browse the homepage (step S26).

On the other hand, when connected to the specific ISP 3A, as shown in FIG. 8, only a home page having address information recorded in advance in the storage device 35A of the specific ISP 3A can be browsed. Even if a URL other than the above is input, the user is not connected to the homepage and cannot browse (step S31). Specific ISP
In 3A, browsable home pages are divided into predetermined groups (for example, A, B, and C groups), address information is recorded in the storage device 35A for each group, and the client 1 connects with the school ID. If so, only the home page provided by the address information classified into the group C can be browsed (step S3).
2). When the client 1 is connected with the minor ID, only the home page provided by the address information classified into the groups B and C can be browsed (step S33). When the client 1 is connected with the adult ID, the home page provided by the address information classified into all groups can be browsed (step S34).

On the other hand, the address information of the homepage that can be viewed is registered in the address information database 4a of the management server 4 that centrally manages the address information of the homepage that is permitted to be viewed. Then, the management server 4 checks each specific ISP 3A and special ISP 3
B to the specific ISP 3A and the special ISP 3B, and transmits the address information, which can be browsed through the communication line 9, to the specific ISP 3A.
The address information registered in the SP3A and the special ISP3B is sequentially updated. This allows browsing of a new homepage.

[0038]

According to the homepage browsing method and system according to the present invention, the client is configured so as to be able to connect only to the ISP that can view only the pre-registered homepage. Only the homepage can be browsed, and accordingly, browsing of other homepages including a homepage that provides content information harmful to minors or the like can be properly prohibited. Therefore, a parent who does not want to allow a child to browse a homepage that provides harmful content information can also prepare an Internet connection environment at home without hesitation. Therefore, there is an effect that it becomes possible to accelerate the spread of IT technology.
