Description

Internet paid site access blocking device

The present invention relates to a connection between a personal computer and the Internet, and more particularly, to an Internet pay site connection blocking device for preventing unauthorized access to a pay site 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, a growing number of commercial sites are accessed only by paying a fee, etc., and a lot of costs are incurred by a beginner or a minor inadvertently accessing such a commercial site.

Therefore, it would be desirable to block indiscriminate access to paid sites on the Internet.

Therefore, an object of the present invention is to provide an internet pay site access blocking device that can block or prevent access to a pay site of the Internet.

Internet paid site access blocking device according to the present invention for achieving the above object is a web browser execution unit for executing the access to the Internet pay site according to the Internet site access request input from the key input unit, and the connected Internet pay site And a password input request detector for retrieving the password input request signal provided from the key input unit to invalidate the Internet access request input generated from the key input unit.

The above and other objects and various advantages of the present invention will become more apparent from the preferred embodiments of the present invention described below with reference to the accompanying drawings.

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

2 is a block diagram of a device for blocking unauthorized access to an Internet pay site configured according to the present invention, the device comprising a key input unit 110, a web browser execution unit 120, an Internet pay site 130, a password input The routine detector 140 and the monitor 150 are included.

The web browser execution unit 120 operates the LAN card modem and the PC system connected to the network service or the PC communication service 30 similarly to the hardware unit 10 and the system software unit 40 of the PC system shown in FIG. 1. It includes Windows and other Unix-like O / S software for operating system and various protocols necessary for internet access, and uses it to run web browsers such as Netscape Navigator or Explorer. Therefore, the web browser execution unit 120 accesses the Internet pay site according to the connection request from the key input unit 110 to the Internet and the access request to the Internet site.

The Internet service site 130 has a unique address called a Uniform Resource Locator (URL), and the service information provided by them is written in a hypertext document using a format called HyperText Markup Language (HTML). The Internet service site 130 that services information for a fee has a routine for inquiring an ID or password of a user. Or, in the case of Java applets, text fields have routines for handling passwords. Accordingly, these Internet pay sites 130 send a request through the web browser 120 to enter the ID or password included in the password routine described above.

The password input request detector 140 detects the password input request signal provided from the connected Internet pay site and invalidates the Internet site access request input generated from the key input unit 110 to block indiscriminate access to the Internet pay site. .

Operation of the Internet pay site access blocking device according to the present invention having the above-described configuration will be described in detail as follows.

When the web browser execution unit 120 is connected to the Internet, the user enters a domain name and an IP address to be accessed through the key input unit 110 to find a desired Internet service site 130. The connected Internet service site 130 is displayed on the row monitor 150 through the web browser execution unit 120.

If the current Internet site found through the key input unit 110 is a paid Internet site 130, the paid Internet site 130, via the web browser 120 to request to enter the ID or password included in the above-described password routine Send it.

This request signal is displayed on the monitor 150 as text through the web browser 120, and is also input to the password input request routine detection unit 140 of the present invention. The user may download desired information from the Internet site 130 by inputting his or her ID or password according to the password input request displayed on the monitor 150.

The password input request detector 140 detects the password input request signal provided from the Internet site 130. This detection involves searching for the word ID or password in the input request signal. Therefore, when such a word is found, the password input request detector 140 causes the web browser execution unit 120 to invalidate a key input input from the key input unit 110, that is, input of a user ID or password. . Therefore, since the input generated from the key input unit 110 is not provided to the Internet site 130, the connection with the Internet pay site 130 is blocked.

Therefore, according to the present invention, when accessing an Internet pay site, a word such as a password requested from the pay site is searched to invalidate the access to the pay site, thereby preventing the indiscriminate access.
