[0030]

FIG. 1 is a diagram showing an outline of one embodiment of the present invention. Terminals such as mobile phone 1
By wirelessly connecting to the base station 2 and accessing the Internet 4 via a network device 3 such as a gateway, various contents and information provided by various sites (WWW servers) 5a, 5b on the Internet 4 can be browsed. It is possible to send, acquire, or write to the sites 5a and 5b.

As described above, the number of sites 5a and 5b on the Internet 4, which are not suitable for adults and for the education of other children, is very large. Every day, the number is increasing or changing. It takes a lot of work to search the site one by one and set the prohibition of access to the site on the mobile phone 1.

In this embodiment, an access management site 6 connected to the Internet 4 is provided. The access management site 6 provides a user with an access management service when a terminal such as the mobile phone 1 accesses a site on the Internet 4.

That is, when the user's mobile phone 1 accesses a site on the Internet 4, for example, 5a, the uniform resource locator (URL) of the site 5a that accesses the management site 6 and the mobile phone 1
After transmitting the identification information and the permission level set in advance to the permission signal from the management site 6, the contents and information from the accessed site 5a on the Internet 4 are displayed on the display on the mobile phone 1. Alternatively, output is performed by voice or the like. If the prohibition signal is received from the management site 6, the content or information from the accessed site 5a on the Internet 4 is not displayed or output on the display of the mobile phone 1, and the inaccessible display is displayed. Or output.

Therefore, as shown in FIG. 2, in the mobile phone 1, the identification information input means 11 for setting and storing the identification information 1a of the terminal in advance and the level input for setting and storing the access permission level 1b in advance. Means 12 are provided. The identification information input unit 11 and the level input unit 12 store the identification information 1a and the setting level 1b in the EEPRO in the mobile phone 1.
It is stored in the nonvolatile storage device 13 such as M. The identification information 1a of the mobile phone 1 is given to the user by the operator of the access management site 6 that provides access management based on the contracted service contract for Internet access management, and uniquely identifies each terminal. This is information used for the operation, and may be a number of necessary digits.

Internet access permission level 1b
Can be configured as a table as shown in FIG. 3, for example, and the level can be set for each category of the Internet site. Then, different permission levels may be set for pornographic sites (for example, category 1) and dating sites (for example, category n). Category 0 may represent a permission level applied uniformly to all categories.
The permission level may be set by the numbers 0, 1, 2, 3, 4 and, for example, level 0 has no restriction,
Level 4 is the most restrictive level, Level 1,
Two or three may represent the level of severe restrictions in sequence. Further, when the permission level of category 0 is other than level 0, access to all sites stored in the access management site 6 may be prohibited regardless of the category as a restricted URL described later.

Referring again to FIG. 2, when the mobile phone 1 accesses a site on the Internet 4, for example, 5a, the uniform resource locator (URL) of the site 5a on the Internet 4 is input by the URL input means 14.
, The data including this URL is transmitted via the Internet 4 by the communication control means 15 in the mobile phone 1, and the content and information C from the site 5a is received. At that time, the mobile phone 1 At the same time, the communication control means 15 of the communication control unit 15 provides the access management site 6 with its own identification information 1a, the setting permission level 1b (for example, the table of FIG. 3), and the information of the uniform resource locator (URL) of the desired internet site 5a. The signal S containing is transmitted.

Further, as shown in FIG. 2, the access management site 6 on the Internet 4 is provided with a terminal, a mobile phone 1, a notebook personal computer, a desktop, which is given based on a contract for providing an access management service.・ Personal computer, personal
There is a terminal database 61 that stores identification information 1a for each item such as digital assistance.

The terminal database 61 may be constructed, for example, as shown in FIG. When a contract to provide Internet access management services is signed, at any time,
The operator of the access management site 6 stores in the terminal database 61 the identification information 1a (SR1, SR) of each user terminal.
, ..., SRn) are stored. Each identification information 1a includes
Required user information such as the name and address of the user of the terminal 1
To user address n are stored in association with each other. Further, a valid flag 1 indicating that the access management service is available or an invalid flag 0 indicating that the access management service is unavailable is associated with each identification information 1a and stored. Further, the date of start and end of use of the terminal is stored in association with each piece of identification information 1a. After the use end date, the valid flag 1 is automatically changed to the invalid flag 0.

This terminal database 61 is stored in the terminal database 61 on a regular basis (valid flag 1 is set).
The access management site 6 may use it when issuing a bill for a charge as a consideration for providing the Internet access management service to the address of the stored user information 1 ... N based on the identification information 1a. . If the fee is not paid, the access management site 6 changes the valid flag 1 for the corresponding identification information in the terminal database 61 to the invalid flag 0, and the access management site 6 thereafter.
The service provision of may be stopped.

Further, referring to FIG. 2 again, the access management site 6 includes uniforms of Internet sites, which are classified into categories and whose access is restricted.
There is a restricted URL database 62 containing resource locators (URLs) and their levels. This limit UR
The L database 62 is a uniform resource locator of a site on the Internet 4 that needs to be prohibited or restricted by the operator of the access management site 6 on a daily basis to correspond to newly opened Internet sites. (URL) and levels are added, deleted, or updated at any time in units of categories to provide terminals such as the mobile phone 1 with efficient access management to sites on the Internet.

The restricted URL database 62 may be constructed as shown in FIG. 5, for example. The restricted URL includes uniform resource locators (URL1, UR) of multiple sites on the Internet to which access should be restricted.
L2, ..., URLn are stored, and in each uniform resource locator (URL1, ..., URLn), the total number of access requests from the user's terminal (access frequency) and the previous URL are stored. Of the update date of the level (last update date), the number of days elapsed from the last update date to the present (update interval), and the level for each category (category 1, ..., Category n) of the URL. Are stored in association with each other.

For example, category 1 shows pornographic sites, and category n shows dating sites. Level 0 means that access need not be restricted from the perspective of this category. This means that sites with level numbers 1, 2, 3, 4 prohibit access to terminals for which the user has set a permission level that is the same as or higher than this number.

For example, in FIG. 5, URL1 is level 3 as category 1 (for example, pornographic site).
Therefore, it is a site where access to the terminals set to permission levels 3 and 4 by the user for category 1 is prohibited. On the other hand, the terminals for which the user has set permission levels 0 to 2 for this category 1 are sites where access is permitted. Since this URL1 is level 2 as category n (for example, dating site), access is prohibited to terminals set to permission levels 2, 3, and 4 by the user for this category n. On the other hand, the terminal for which the user has set the permission level 0 or 1 for this category n is a site where access is permitted.

Since URL2 is level 0 as category 1 (for example, a pornographic site), access to all terminals is not prohibited for category 1. Since this URL2 is level 1 for category n (for example, dating site), access to the terminals for which the user has set permission levels 1, 2, 3, and 4 is prohibited for this category n. Is. On the other hand, the terminal for which the user has set the permission level 0 for this category n is a site where access is permitted.

Further, referring to FIG. 2, the access management site 6 has an inquiry and determination means 63, and the identification information 1a and the setting level 1b transmitted from the terminal such as the mobile phone 1 via the Internet 4. Then, a signal S including a uniform resource locator (URL) of a site desired to be accessed, for example, 5a is received, and the terminal database 61 and the restricted URL database 62 are inquired to make a determination. If you query the terminal database 61,
The received identification information 1a is stored as valid in the terminal database 61 (that is, the valid flag is 1), and the received desired URL for access and its permission level are restricted to the restricted URL database 6 for each category.
As a result of referring to the URL in 2, if at least one category corresponds to the level of the URL of the Internet site where access is prohibited, the access prohibition signal N is returned to the mobile phone 1 which has transmitted the signal S. To do. In other cases, the access permission signal Y is returned to the mobile phone 1 that has transmitted.

When the mobile phone 1 receives the prohibition signal N from the access management site 6 as a reply to the transmission signal S, the contents and information C of the desired access site 5a received via the Internet 4 are displayed on the display 16. The display is prohibited (and the audio output may be prohibited), and the inaccessible display or output is performed. The mobile phone 1 uses the access management site 6 as a response to the transmission signal S.
When the permission signal Y is received from, the contents and information C of the desired access site 5a received via the Internet 4 can be displayed on the display 16 (voice output is also possible).

Next, with reference to FIG. 6, the configuration of the mobile phone 1 of the embodiment shown in FIG. 2 will be described in more detail.
The mobile phone 1 has a computer program (browser program) for internet connection and browsing.
Are stored in advance in a non-volatile storage device 13 such as an EEPROM. Both the identification information input means 11 and the level input means 12 described above can be configured as a part of the functions of this browser program. This browser program, like a conventional browser program, accesses a site on the Internet 4 to receive contents and information, and therefore inputs a uniform resource locator (URL) of the site on the Internet. It has a URL input means 14.

As described above, in the mobile phone 1 of this embodiment, a site on the Internet 4, for example,
5a, when the uniform resource locator of the site 5a is entered from the URL input means 14, the communication control means 13 similarly configured as a part of the browser program will access the site 5a desired to access. To the access management site 6 on the Internet 4 at the same time as the identification information 1a of the mobile phone 1 and the permission level 1b and the uniform of the site desired to be accessed.
A signal S including a resource locator (URL) is transmitted. And the communication control means 1
5 is an access management site 6 as a response to the transmission signal S.
When the prohibition signal N is received from the display device 16, the display of the content or information C of the desired access site 5a received via the Internet is prohibited (and the audio output is also prohibited), and the display of the inaccessibility or Output. When the communication control means 15 receives the permission signal Y from the access management site 6 as a reply to the transmission signal S, the contents and information C of the desired access site 5a received via the Internet can be displayed on the display 16. Yes (audio output is also possible).

As described above, the mobile phone 1 according to the present embodiment can be realized by incorporating the above-described new function of the present embodiment into the browser program stored in advance in the mobile phone 1. it can. The present invention can be realized by the browser program thus stored in the terminal.

FIG. 7 shows the configuration of the access management site 6 of this embodiment shown in FIG. 2 in more detail. The access management site 6 inquires the identification information 1a of the terminal in the signal S received from the terminal such as the mobile phone 1 as the identification information of the valid terminal stored in the terminal database 61, and determines whether or not the identification information is valid. The UR stored in the restricted URL database 62 of the terminal determiner 63a that determines whether or not the URL desired to be accessed in the signal S received from the terminal such as the mobile phone 1 is stored.
It has a URL search unit 63b that searches for and searches from L.

If the terminal determiner 63a is the mobile phone 1
The identification information 1a of the terminal in the signal S received from the terminal such as the identification information not stored in the terminal database 61 (for example, shown in FIG. 4) or the identification of the terminal invalid (flag is 0) even if stored When the access management site 6 determines that the information is information, the access management site 6 transmits a permission signal Y to a terminal such as the mobile phone 1 as a response to the signal S. If the identification information 1a of the terminal in the received signal S is valid (flag is 1) identification information stored in the terminal database 61, the permission in the signal S received by the next URL searcher 63b. Limit the level and the URL you want to access URL database 6
Inquire as 2.

If the URL searcher 63b receives the desired URL in the signal S received from the terminal such as the mobile phone 1 or the like.
Is a restricted URL database 62 (for example, shown in FIG. 5)
If it is determined that the URL is not stored in the access management site 6, the access management site 6 transmits a permission signal Y to the terminal such as the mobile phone 1 as a response to the signal S.

If the terminal identification information in the signal S received from the terminal is valid and the desired access URL in the signal S is stored in the restricted URL database 62,
If it is L, the category and level determiner 63c in the access management site 6 stores the category in the received signal S, the permission level 1b (for example, the table shown in FIG. 3), and the restricted URL database 62. The category and the level (for example, shown in FIG. 5) are compared and determined.

If the permission level 1b in the received signal S
Are all level 0 or restricted U in the category
The number is smaller than the level of all categories of URLs matching the desired access URL in the RL database 62, or the level of all categories of URLs matching the desired access URL in the restricted URL database 62 is 0. If so, the category and level determiner 63c transmits a permission signal Y to a terminal such as the mobile phone 1 as a response to the signal S.

In cases other than the above (that is, the permission level 1b in the received signal S is at least one category, and the desired U in the restricted URL database 62 is desired to be accessed).
If the URL is the same as or larger than the level of the URL matching the RL), the category and level determiner 63
In response to the signal S, c transmits a prohibition signal N to a terminal such as the mobile phone 1.

When the level of category 0 at the bottom of the table of permission level 1b shown in FIG. 2 is other than 0,
This restricted URL database 6 regardless of category
Some sites completely prohibit access to URL sites stored in 2, so the category and level determiner 63c transmits a prohibition signal N to a terminal such as the mobile phone 1 in response to the signal S. To do.

FIG. 8 shows a flowchart of the access management method of this embodiment. In FIG. 8, steps S1 to S5 and steps S12 to S15 are processes performed on the terminal side such as the mobile phone 1, and steps S6 to S11 are processes performed on the access management site 6 side.

First, when the method is started, the mobile phone 1
Alternatively, the identification information of the terminal is input to another terminal (S1). Next, the category and level of the Internet site to which access is restricted at the terminal are input to the mobile phone 1 or another terminal (S2). When the terminal accesses a desired site on the Internet, the desired URL is input (S3). If the identification information is not entered in the mobile phone 1, the mobile phone 1 is not the target of access management, and thus step S1
Jump to step 4 to receive content or information from the Internet site with the desired URL, and display it as is on the display screen of the mobile phone 1 (S1).
5). And it ends.

If the identification information is entered in the mobile phone 1, the mobile phone 1 is subject to access management, and the identification information is stored in the access management site 6 from the mobile phone 1 via the Internet. , A signal including the category and level to which access is restricted and the URL of the Internet site desired to be accessed is transmitted (S5).

If the identification information received from the mobile phone 1 via the Internet is valid identification information stored in the terminal database, the access management site 6 proceeds to step S8, and the received identification information is the terminal information. If it is not the valid identification information stored in the database (for example, if the identification information is not stored at all in the terminal database 61 or is invalid even if it is stored), the process proceeds to step S7. In step S7, the permission signal Y
Is transmitted as a response to the mobile phone 1 via the Internet.

As described above, according to the present invention, if the identification information and the level for permitting the access on the Internet are set on the terminal side, the daily access control to the Internet can be controlled through the Internet. Since it can be entirely entrusted to the access management site, it is not necessary for the terminal side to have data about sites on the Internet to which access should be restricted, and the trouble of access management can be eliminated. Also, the terminal side need only store the identification information of the terminal and the access permission level,
Access to a site on the Internet can be efficiently managed at a high response speed even in a small mobile terminal that does not need to store a database or the like and has a small storage capacity or processing capacity.

The access management site is the Internet
I remember a huge database of sites,
The data processing that the access management site processes is only the reception of a data signal including the desired URL for access from the terminal, the identification information and the permission level, the collation and determination of the received data and the database, and the transmission of the result, The data that the access management site receives from the terminal is, for example, 10
The size is about 0 bytes, the amount of data is smaller than that of the Internet contents of 10 Kbytes or more, the processing is simple and easy, and there is no processing for transmitting / receiving the contents from the Internet site. Therefore, the load on the access management site is small and quick response is possible.

Access control to the Internet, which changes daily, can be provided as a service to users of other terminals such as mobile phones and personal computers via the Internet.
