In general, the Internet is a network of computer networks that exchange data according to a communication protocol called Transmission control protocol / Internet Protocol (TCP / IP). 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.

In other words, the server providing the information is called a server computer, and the client receiving the information is called a client computer. The world wide web (www) 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. 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.

The mail deletion determining unit 22 deletes the unwanted information from the mail stored in the mail storage unit 21 using the data stored in the database 30.

In the mail blocking method according to the related art, referring to FIG. 2, first, a mail is received (S1).

If unwanted mail exists in the received mail, the mail is rejected (S2-S3).

On the other hand, if there is no unwanted mail in the received mail is notified to the user (S4).

As described above, the mail blocking device according to the related art is connected to the Internet by the mail server 20 and stores the domain or IP address of the provider of the mail delivered through the mail provider 10 in the database 30. ), If the unwanted domain or IP address is entered through comparison with the registered data, the corresponding mail is deleted.

However, as described above, the mail blocking apparatus according to the related art has a problem in that it cannot be blocked when the mail provider changes the domain or the IP address.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a mail blocking device and method for blocking mail using unwanted text or unwanted company information.

The first embodiment of the mail blocking device according to the present invention for achieving the above object is a plurality of mail providers for providing a variety of information, a database for storing a string that the user does not want, and through the mail provider It is characterized by being configured as a mail server to detect whether there is a character string previously stored in the database from the received various information, to block the mail or to notify the user.

The first embodiment of the mail blocking method according to the present invention for achieving the above object comprises the steps of receiving a mail, determining whether there is a text that the user does not want in the received mail; Blocking the mail if a text that the user does not want exists in the received mail; and notifying the user of the received mail if the text that the user does not want exists in the received mail. It is characterized by.

A second embodiment of the mail blocking device according to the present invention for achieving the above object is a plurality of mail providing unit for providing a variety of information, and an information providing unit for providing the address information of the mail received through the mail providing unit And a database for storing an address of a mail server that the user does not want, and address information corresponding to an address previously stored in the database by receiving address information of the mail received through the mail provider from the information provider. It is characterized by including a mail server that blocks mail if it exists.

A second embodiment of a mail blocking method according to the present invention for achieving the above object is a mail blocking method of a mail blocking device having a database and a domain information providing server, wherein the data of domain information of a company that a user does not want is changed. Storing in the base, receiving domain information of the received mail from the domain information providing server, and blocking mail received from the corresponding domain if the transmitted domain information matches the previously stored domain information in the database. It is characterized by including the step of making.

Hereinafter, a mail blocking device and method according to the present invention will be described in more detail with reference to the accompanying drawings.

Figure 3 is a view showing a first embodiment of the mail blocking apparatus according to the present invention, Figure 4 is a flow chart showing a first embodiment of the mail blocking method according to the present invention, Figure 4 is a mail blocking according to the present invention A second embodiment of the apparatus is shown, and Fig. 5 is a flow chart showing the second embodiment of the mail blocking method according to the present invention.

First embodiment

As shown in FIG. 3, the first embodiment of the mail blocking device according to the present invention includes a plurality of mail providers 100 for providing various types of information and a database 120 for storing character strings that are not desired by a user. And a mail server 110 for detecting whether a string previously stored in the database 120 exists in various information received through the mail providing unit 100 to block or notify a user of the mail. And a monitor 130 for displaying the received mail.

When the mail blocking device configured as described above receives a plurality of mails from the mail provider 100, the mail server 110 receives the mail and checks whether there is a mail in which a text string previously stored in the database 120 exists. Detects and blocks the mail if there is already saved text (Text).

Referring to FIG. 4, the first embodiment of the mail blocking method according to the present invention first receives a mail (S11).

Subsequently, it is searched whether there is a character string previously stored in the database in the received mail (S12).

The search result (S12), it is determined whether there is a character string previously stored in the database (S13).

Subsequently, if there is a character string previously stored in the database as a result of the determination (S13), the mail reception is rejected (S14).

On the other hand, when the determination result (S13), if the character string previously stored in the database does not exist, the corresponding mail is received and notified to the user (S15).
