System to cut children off from harmfum Internet sites and to search the Internet sites}

The present invention relates to a blocking and retrieval system of harmful Internet sites, and in particular, to automatically access the Internet site providing harmful site information and periodically update the list of harmful sites, so that harmful sites can be effectively blocked. It's about a system.

As the Internet is widely used, it has become a part of daily life, and the number of Internet sites that provide various services through the Internet is increasing rapidly.

Internet sites provide many useful services and are very helpful to Internet users in combination with the characteristics of the Internet without time and space constraints. However, there are not many Internet sites that provide unhealthy information or harmful information to minors, and it is true that many of them are causing harm to minors due to the nature of the Internet that anyone can easily use.

Therefore, when using the Internet using a computer, the program is configured to periodically save the Internet screen and search and display various images and videos stored on the computer so that parents can select harmful Internet sites and block their access. It is distributed and used.

Conventional harmful site blocking program, which is used to block harmful Internet sites, is configured to block the sites by searching for traces (eg images, videos, etc.) used by children, so that parents who do not have enough knowledge about the Internet It was difficult to effectively block harmful sites.

In particular, due to the nature of the Internet, where many sites are opened and closed in one day, parents cannot quickly find new harmful sites, which is a major factor that makes precautions difficult. In addition, there is a problem that the blocking effect is reduced because a variety of means for children to better control the image or video, such as children having better Internet knowledge than parents.

Accordingly, the present invention has been made to solve the above problems, by configuring a site blocking means installed on the user's computer to automatically access the Internet site providing harmful site information to periodically update the list of harmful sites, Its purpose is to provide a system that can effectively block harmful sites and prevent access.

In order to achieve the above object, the harmful Internet site blocking and retrieval system according to the present invention periodically collects a harmful site list, stores it in a database, and the version of the harmful site list previously transmitted from the user computer An Internet site (update site) which transmits the upgraded harmful site list to the user's computer when the current version is upgraded when receiving the information, compared to the version information of the harmful site list currently stored in the database; An internet network connecting the update site with a user computer; And installed on the user's computer to automatically access the update site at predetermined update periods, to transmit version information of a list of harmful sites currently owned by the user, and to transmit the version information when the version is upgraded. And a site blocking means for receiving the site list and automatically updating the harmful site list of the user's computer.

Here, it is preferable that the site blocking means is configured to be executed only when a preset password is input so that children do not arbitrarily change the setting contents.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a preferred embodiment of the system according to the present invention, which is a site blocking means 12 installed on the computer 10 of each user, and periodically collects a list of harmful sites and lists a harmful site list database. (31: hereinafter referred to as a database) Internet site for transmitting a list of new harmful sites at the request of the site blocking means 12 (30: hereinafter referred to as an update site separately from the general Internet site), and It consists of an internet network 20 connecting the user computer 10 and the update site 30 with each other.

Here, the site blocking means 12 means a computer program installed and operated on the user computer 30, and the computer program is provided to the subscriber who has subscribed to the update site 30 through the Internet network 20 or It may be distributed in a state of being stored in a storage medium, such as a CD-ROM. Since the communication between the site blocking means 12 and the update site 30 is not only involved with the user computer 10 having the site blocking means 12 installed therein, the site blocking means 12 and the update site 30 communicate with each other. It will be used in the same sense as the communication between the computer 10 and the update site 30.

The site blocking means 12 installed on the user computer 10 basically searches for all files that may contain harmful information such as image files or video files stored on the hard disk drive (HDD) of the user computer 10. To display them in order. In other words, parents can automatically check what data is stored on their computers.

In order to perform this basic function, the site blocking means 12 captures and stores a screen of the Internet site at regular intervals while the user computer 10 is connected to the Internet. Record it so that if the user later clicks on the image, he or she will be taken to that Internet site. Then, from the parent's point of view, it is possible to easily visit the Internet site that provided the image stored in the child's computer, it is possible to determine more accurately what site.

In addition, the site blocking means 12 is linked to the web browser 11 to perform each function, which will be described below, harmful site file 13, keyword file 15, allowed site file 15, the Internet Various files such as the usage history file 16 are used.

At this time, the Internet history file 16 is a file that stores the information of the Internet site that the user computer 12 has previously accessed, and is composed of a file that cannot be accessed unless a user inputs a password and obtains permission. desirable. Although the Internet access history is managed by the operating system installed in the user's computer 10 in a separate directory (eg Internet Temporary), these problems are already well known, so children may access and delete the information. Because it can.

A function performed by the update site 30 will be described in detail with reference to FIG. 2.

The update site 30 collects a list of harmful sites periodically (or whenever necessary) and stores the list of harmful sites in the database 31 to maintain the latest harmful site list (S2-1).

When receiving the upgrade request of the harmful site list from the user computer 10 (S2-2), the version information of the harmful site list stored in the harmful site file 13 of the user computer is received and the current database 31 is received. Compared to the version information of the harmful site list stored in the (S2-3). Here, the request in step S2-2 is a function performed by the site blocking means 12.

When the version of the harmful site list currently stored in the database 31 is a higher version (S2-4), the update site 30 upgrades to the user computer 10 when the comparison result in step S2-3 is performed. Sends a list of harmful sites (S2-5).

Referring to Figure 3, the function of the site blocking means 12 installed in the user computer will be described in detail.

The site blocking means 12 determines whether a predetermined update period has been reached and reaches the update period (S3-1), and automatically connects to the update site 30 (S3-2). Then, while requesting the upgrade of the harmful site list, it transmits version information of the harmful site list which it currently has (S3-3), and waits for a response from the update site 30 for a predetermined time. Preferably, if there is no response from the update site 30 for a predetermined time, the process returns to step S3-3 to repeat the request for a predetermined number of times.

When the version is upgraded during the waiting in step S3-4, when the harmful site list transmitted from the update site 30 is received (S3-5), the newly received harmful site file 13 stored in the user's computer is received. After adding and updating the harmful site list (S3-6), the connection to the update site 30 is terminated (S3-7).

Since the site blocking means 12 described above should be managed only by the parents from the user's point of view, the site blocking means 12 should be configured so that only the authorized user can execute the password by entering a password. desirable.

Specifically, referring to FIG. 4, when there is an attempt to change the setting state during initial execution or during execution (S4-1), the site blocking means 12 requests the user to input a password to input the password from the user. (S4-2, S4-3).

Then, the passwords input in step S4-3 are compared with the preset password (S4-4), and if they are the same, execution starts or changes the setting contents (S4-6). If not, output an error message and stop execution (S4-7).

On the other hand, in addition to the list of harmful sites that are transmitted in a batch from the update site 30, the user may want to block or allow individually. Therefore, the site blocking means 12 allows the authorized user to add the Internet site that is the target of the access blocking to the harmful site file 13 of the user's computer, or delete certain items of the harmful site file 13. desirable.

Specifically, referring to FIG. 5, when the user requests to add a specific Internet site to the harmful site file 13 (S5-1), the site blocking means 12 displays an address of the corresponding Internet site designated by the user. It is added to the harmful site file 13 (S5-2). At this time, the designation of the harmful site may be directly typed on the message input screen provided by the site blocking means 12, but may be configured to be operated by operating a predetermined key or mouse button while accessing a specific Internet site. .

In addition, when the user requests to delete a specific item from the harmful site file 13 (S5-3), the address of the corresponding Internet site designated by the user is deleted from the harmful site file 13 (S5-4). At this time, the designation of a harmful site can be configured to be performed by directly operating a predetermined key or mouse button while directly typing or accessing a specific Internet site as in the case of adding a harmful site.

Various harmful sites often contain a certain word in the site address. For example, pornography sites often contain the word "sex."

Therefore, the site blocking means 12 receives the keyword from the user whose authority is confirmed, stores the keyword in the keyword file 14, and stores the keyword in the Internet site address which attempts to access through the web browser 11 of the user's computer. If is included, blocking the connection allows for more comprehensive connection control.

This will be described in detail with reference to FIG. 6.

The site blocking means 12 processes the user to input the keyword when the user requests the blocking by the key (S6-1), and then receives the keyword and stores the keyword in the keyword file 14 (S6-2). . Subsequently, when a connection to an Internet site is attempted through the web browser 11 (S6-3), it is checked whether the keyword recorded in the keyword file 14 is included in the current Internet site address (S6-3). -5) If it is included (S6-5), the connection to the corresponding Internet site is blocked (S6-6), otherwise the connection is allowed (S6-7). Since a technique for blocking access to an Internet site is already implemented in a program for harmful sites and is well known, a detailed description thereof will be omitted.

Blocking access by keywords can be applied to the keywords entered in the search box as well as the address of the Internet site to which you are currently accessing. You may be able to decide whether or not.

In this case, even if the Internet site address including the keyword set to block harmful sites may not be harmful sites, there may be cases where the keyword is not harmful sites even if the keyword is included in the contents of the site. Keywords treated as articles in newspapers).

Therefore, it is preferable that the site blocking means 12 can selectively set whether to allow access even to an Internet site including a keyword previously specified in the address. In this case, the site blocking means manages the allowed site information separately in the allowed site file 15. When the access blocking function by the keyword is performed, the site blocking means 15 retrieves the contents of the allowed site file 15, and then the allowed site file. Block only if the site is not in (15).

On the other hand, in addition to the images and videos recorded on the user's computer, if you provide a list of various information related to the site that your children have access to it will be able to more efficiently identify and guide their children.

This will be described in detail with reference to FIG. 7.

When the user computer 10 accesses the Internet (S7-1), the site blocking means 12 stores the Internet usage history information such as an address, an access time, and an end time of the corresponding site in the Internet history file 16 ( S7-2).

In addition, the site blocking means 12 displays the list of the Internet usage history file 16 on the screen when the user whose authority is confirmed requests an inquiry of the Internet access history (S7-3). When the user clicks on any item in the list displayed in step S7-4 (S7-5), the user is automatically connected to the corresponding Internet site (S7-6). If it is requested to set whether or not to block (S7-7), it is possible to set whether or not to block the corresponding item and then reflect this to the harmful site file (13) (S7-8). Steps S7-5 to S7-8 are of course performed until the user ends this function (S7-9).

The connection history information of the Internet as described above may be provided as various statistics, and since parents can more specifically grasp the propensity of their children, effective instruction will be possible.

Specifically, referring to FIG. 8, if the site blocking means 12 receives a request for statistical information from the user whose authority is confirmed (S8-1), the site blocking means 12 provides statistical values with respect to the information recorded in the Internet usage history file 16. After calculating (S8-2), the statistical value is displayed in a predetermined form (S8-3).

Of course, the statistical value may be calculated for various items such as access time zone, number of times of use, time of use, number of times of connection by site, and may be output in various forms such as a bar graph, a chart form, and a pie chart. In the example of FIG. 9, since the Internet access status of each time zone is displayed as a bar graph on the screen 10-1 of the user's computer, parents can accurately grasp their children's Internet usage.

In addition to this embodiment, more effective control can be made by setting a time zone for the user's computer to access the Internet, such as a time zone for parental monitoring. In other words, the site blocking means 12 allows a user whose authority is confirmed to set the Internet usage time, and blocks the Internet access except for the set time.

This will be described in detail with reference to FIG. 10.

If the site blocking means 12 requests a time setting from the user (S9-1), the user can set the time zone and records it (S9-2). At this time, the time zone may be set to type each allowable time zone, but it is more preferable to display each time zone by section and allow the user to select the allowed time zone by clicking the mouse.

If there is an attempt to connect to the Internet at any point in time (S9-3), it is determined whether the time zone is set in step S9-2 (S9-4), and if the allowed time zone is allowed, otherwise the connection is allowed. The connection is blocked (S9-5 to S9-7).

In addition, the site blocking means 12 may be configured to include a function for displaying warning information indicating that the user is being performed on a predetermined portion of the user's computer screen according to the user's command in which the authority is confirmed. Then, since the children can know that their internet history is left behind, they will refrain from accessing harmful sites, thereby enjoying a blocking effect.

By using the present invention, the list of harmful sites constantly occurring from the perspective of the user, which is a user, can be automatically updated periodically, and harmful Internet sites can be blocked at the keyword level, thereby effectively preventing children from being exposed to harmful Internet environments. have.

In addition, it is possible to find out their children's Internet usage through statistical data, and it is possible to allow their children to use the Internet only at certain times, thereby enabling their children to be more effectively guided.

In addition to this, a careful management is possible by allowing the children to directly access the relevant Internet sites and determine the harmfulness, instead of simply providing images or videos of the Internet sites that their children have previously accessed.
