Description

Internet harmful site access restriction device

The present invention relates to a connection between a personal computer and the Internet, and more particularly, to an Internet harmful site access limiting device for restricting unauthorized access to harmful pornography sites of the Internet.

As is well known, the Internet started out as a special military computer network and is now used as a popular network connecting computers from almost every country in the world. Technically, the Internet is a network of computer networks that exchange data according to a communication protocol called transmission control protocol / internet protocol (TCP / IP). It is not possible to connect all the computers to a central network, but to satisfy a certain protocol, any network can be easily connected, and as a result, a large number of computers can be connected.

In general, services using the Internet have a client / server structure in which one computer requests information from another computer and the requested computer passes the requested information. The one that provides the information is called the server computer, and the one that receives the information is called the client computer. The World Wide Web is also a client / server architecture Internet service that uses a communication protocol called Hyper Text Transfer Protocol (http). A collection of information provided by a web server computer is called a web site. If the web server computer is a TV station, the web site is a channel.

A web browser that receives information from the Internet is a TV receiver in terms of TV broadcasts. As a user, you will be able to use the World Wide Web right away by learning the web browser. The complex internal tasks of the World Wide Web are handled by the web browser, so the user only has to manipulate the web browser as he would handle a remote control.

In order to access the Internet for information retrieval using a web browser, a monitor, a display device, and a computer, which is a terminal device, must be connected to a network or a telephone line. 1 is a block diagram of a conventional Internet connection.

The hardware unit 10 includes a LAN card modem connected to a network service or a PC communication service 30 and a monitor 20 which is a 486 or more multimedia computer and a display part in a conventional PC.

The system software unit 40 is an operating system (O / S) for operating a PC system, Windows or other Unix-like O / S software, and various protocols required for accessing the Internet, for example, TCP / IP (transmission control). protocol (PPP), point-to-point protocol (PPP), MIME, hyper text transmission protocol (HTTP), and hyper text markup language (HTML).

The application software unit 50 is a web browser utilized in an existing PC and includes a Netscape Navigator or various software plugged into it.

In the above-described Internet-connected PC system, the hardware unit 10 of the PC system is booted by using the O / S in the system software unit 40 to access the Internet, and the network service (using the modem in the hardware unit 10) is used. After running the telephone network access program through 30), a program such as a web browser of the application software unit 50 is executed.

However, with the commercialization of the Internet, harmful service sites such as adult service sites and pornographic service sites are provided, and more and more cases of minors are indiscriminately accessing such sites. In addition, due to the widespread use of computers that are accessible to employees in the company as they take advantage of the computerization of their work, they may indiscriminately access harmful sites during work, which may cause huge disruption to productivity and work.

As a conventional technique, there are methods for restricting access to a harmful site by restricting its use through a search for a specific word commonly used on the harmful site except for a specific authorized agent. However, this method has a disadvantage in that it is compelled to forbid unconditionally prohibiting search and access to harmful sites. Therefore, it would be desirable to restrict inadvertently access to harmful sites.

Therefore, an object of the present invention is to provide an apparatus for restricting access to harmful Internet sites, which can restrict access to harmful Internet sites.

According to the present invention for achieving the above object, it is intended to effectively restrict access to harmful Internet sites by warning or recording the fact that Internet access is made through the search of specific harmful Internet sites or specific words. will be. The configuration of the present invention for such an effective limitation is achieved by providing a database with updateable data including a specific word extracted from an address of an Internet site and service information provided from the Internet site; A web browser execution unit that executes access to the Internet site according to an Internet site access request input from a key input unit; A data retrieval unit for retrieving data stored in the database from an address of the connected internet site and service information provided therefrom; A log file recording unit for recording the data retrieved by the data retrieval unit together with a user name and an access time; And a warning sound generating unit for generating a warning sound for limiting the Internet access according to a search result by the data searching unit.
