TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for automatically blocking spam mail through a dynamic URL connection, and more particularly, to extracting URL information linked to a received e-mail, connecting to a corresponding web page, and then performing a predetermined predetermined process. The present invention relates to a method for automatically blocking spam mail through a dynamic URL connection in which a spam keyword is extracted as spam mail and can be automatically blocked.
[0002]
[Prior art]
As is well known, an e-mail system is a system for exchanging data and messages with a specific user through the Internet, and a spam mail (Spam-Mail) is an advertisement that disregards the intention of the recipient and is scattered in large quantities. An email that has a commercial purpose, such as advertising or solicitation. More broadly, commercial advertising information emails against explicit intention to refuse to receive, mass emails sent for the purpose of degrading system performance, sales advertising emails on illegal software that infringes program copyrights, public order and morals, etc. Advertising mails such as harmful adult articles and unhealthy sites, and mails that cause fear or anxiety may be regarded as spam mails.
[0003]
On the other hand, in order to minimize the adverse effects of such spam mail on recipients, the Korean government has various and specific restrictions on spam mail in the Act on Promotion of Information Communication Network Use and Information Protection and its subordinate laws. In case of violation of this, measures are taken so that prescribed penalties can be imposed. For example, it is stipulated that the keywords “(advertisement)” and “(adult advertisement)” are always displayed at the beginning of the title of spam mail. If an e-mail having a keyword as a title is set to be classified as a spam mail, an e-mail having such a title will be automatically classified as a spam mail in the future. Further, at present, a mail client can set an optional keyword for filtering spam mail, and an e-mail including the set keyword in the title or body of the mail is automatically classified as a spam mail. I have. Hereinafter, such a conventional spam mail blocking method is referred to as a “ruler expression formula”.
[0004]
On the other hand, efforts to avoid being produced as spam mail have been further strengthened, but especially in the case of advertisement mail for adult sites, only the image is included in the body under the title of the ordinary mail. In many cases, a method of linking a homepage URL (Uniform Resource Locator) of an adult site is used.
[0005]
[Problems to be solved by the invention]
However, according to the above-described conventional technology, it is only necessary to check whether the spam keyword set by the mail client exists in the title or the body of the received e-mail, and the Web connected to the URL linked to the body of the body is checked. Since the contents of the page are not inspected, there is a problem that the above-described modified spam mail cannot be produced at all.
[0006]
The present invention has been devised to solve the above-described problems, and an object of the present invention is to extract URL information linked to a received e-mail and connect to a corresponding web page. It is another object of the present invention to provide a method for automatically blocking spam mails through a dynamic URL connection in which, when a predetermined spam keyword is specified, the spam mails are extracted as spam mails and can be automatically cut off.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, an automatic spam mail blocking method through a dynamic URL connection according to the present invention is provided in an automatic spam mail blocking method performed in an electronic mail system in which a plurality of mail servers are connected through the Internet. Extracting dynamic URL information existing in the original message of the e-mail; connecting to a web page linked to the extracted dynamic URL information; and having a predetermined spam keyword in the content of the web page. In some cases, the method further comprises the step of classifying the received electronic mail as a spam mail.
[0008]
In the above-described configuration, when a predetermined spam keyword exists in the contents of the web page, the source of the received e-mail is extracted from the original message and stored in the source blocking list database, and the source It is preferable to refuse to receive e-mails from senders in the blocking list database.
[0009]
Preferably, when a predetermined spam keyword exists in the contents of the web page, the dynamic URL information is stored in a URL block list database, and dynamic URL information existing in the URL block list database is included in the original message in the future. Refuse to receive e-mail.
[0010]
Preferably, when there is no pre-defined spam keyword in the contents of the web page, the mail is classified as a general mail, the dynamic URL information is extracted from the original message and stored in a URL passage list database, and the URL is referred to in the future. The dynamic URL information stored in the passage list database classifies the electronic mail included in the original message as a general mail.
[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. This embodiment does not limit the scope of the present invention, but is presented only as an example.
[0012]
FIG. 1 is a network configuration diagram of a general e-mail system. In general, an e-mail client (hereinafter, referred to as a "mail client") 18 connected to the Internet 30 transmits / receives an e-mail. A mail server (hereinafter, referred to as a “mail server”) 12 provided in the web server 10 or various web sites that provide an e-mail service from outside the web site itself, for example, a web site 20 of a large or small portal site or an ISP (Internet Service Provider) 20 An e-mail account is provided from a mail server (hereinafter referred to as an “external mail server”) 24 provided for the user.
[0013]
The web site 10 is formed by connecting a web server 14 for processing web documents, a mail server 12 for sending / receiving mail, and a mail client 18 via a private network 16, for example, a LAN or an intranet. Of course, each external website 20 also has a web server 22 and a mail server 24. In the drawing, reference numeral 40 denotes a personal mail client that is connected to the Internet 30 through a telephone line, cable, satellite, ADSL, ISDN, etc. mainly in a home or a private office without providing its own website. Such a personal mail client 40 mainly uses the electronic mail service after subscribing to the external mail server 24 and assigning a mail account free of charge. Of course, the mail client 18 belonging to the website 10 can also use the electronic mail service by subscribing to the external mail server 24.
[0014]
On the other hand, in the e-mail system described above, an e-mail sent from an arbitrary e-mail client via the internal mail server 12 or the external mail server 24 is transmitted to the e-mail of the receiving e-mail client by a Simple Mail Transfer Protocol (SMTP). It is stored after being transmitted to the mailbox of the internal or external mail server 12, 24 represented by the electronic mail address. Thereafter, the receiving mail client can connect to its own mailbox via the Internet 30 and read the e-mail stored therein. In the method in which the receiving side mail client reads the self-received electronic mail, POP3 (Post Office) is a method in which the electronic mail stored in the mailboxes of the mail servers 12 and 24 is copied to the hard disk of the mail client computer. Protocol # 3: a post office protocol for receiving e-mail from a mail server) and self-received e-mail can be stored in a mailbox without having to copy it to a mail client computer. Although there is an IMAP (Internet Message Access Protocol) method, such POP3 and IMAP are generally widely used in an internal mail server system.
[0015]
On the other hand, recently, in addition to IMAP, a web mail service that stores received mail on the Internet so that it can be accessed from anywhere has appeared. And a web server. In other words, the web mail server seen from the mail client side has exactly the same form as a general web server, so that only the web browser is required for the mail client to access the web mail server, and the e-mail software is No need. Such a web mail function is provided free of charge at various portal sites, ISPs, and the like as a service.
[0016]
FIG. 2 is a flowchart illustrating a method for automatically blocking spam mail by extracting URL information according to an embodiment of the present invention. The program according to the method for automatically blocking spam mail according to the present invention (hereinafter, referred to as a "spam blocking program"). Can be integrated into or separate from the internal or external mail server 12, 24, and in the case of a personal mail client 40, can be integrated with or separately installed in the email software of the client computer.
[0017]
In the following, 'spam keyword' refers to a set of two or more characters that are often used in spam mail. For example, the spam keyword is frequently used in advertising mails such as adult goods and unhealthy sites that are offensive to public order and morals, such as 'sex', 'orgasm', 'nude', and 'pornography' yadon. Abbreviations) ','perverts', or 'masturbation' and the like.
[0018]
As shown in FIG. 2, when an arbitrary e-mail is received in step S10, the spam blocking program performs step S12 to execute a web page (hereinafter, referred to as "dynamic") linked to the original message of the received e-mail. URL ”) and an e-mail source e-mail address (hereinafter, referred to as“ e-mail source ”).
[0019]
For example, FIG. 3 is a diagram illustrating a hop-up window of a received e-mail according to an embodiment of the present invention, and FIG. 4 is a diagram illustrating an original message of a received e-mail according to an embodiment of the present invention. It is.
[0020]
As shown in FIGS. 3 and 4, a normal e-mail is divided into a header part and a body part (Body). The e-mail source necessary for correctly delivering the e-mail is provided in the header part. ( Sda35s5g32-13@yahoo.com ) and the title of the message are described. For example, in the body part, the contents of the body (Nice Buddy) or the homepage of an adult site to be advertised is advertised. URL (a href = " http://www.ohmybuin.com/index.asp?ID=39556623 ") and an image URL including information of a plurality of linked images 100 (IMG alt = OhMyBuin.Com) height = 85src = "http: // ww Only .ohmybuin.com / banners / title.gif "width = 504) information is described.
[0021]
Next, the process proceeds to step S14, where it is checked whether the source of the e-mail is an address registered in a source blocking list (database). A list DB (database) must be operated.
[0022]
If the result of determination in step S14 is that the sender of the e-mail is on the sender blocking list, the process proceeds to step S34, where the reception of the e-mail is refused, for example, the deletion processing is immediately performed without reading the contents of the body. Will do. As a result, the load associated with the mail server (or client) confirming whether the electronic mail is a spam mail can be reduced.
[0023]
On the other hand, if the result of the determination in step S14 is that the sender of the e-mail is not registered in the sender blocking list, the process proceeds to step S16, and the dynamic URL is stored in the web page registered in the URL blocking list (database). An inquiry is made as to whether the address is an address. For this purpose, a spam blocking program must operate a URL blocking list DB (database).
[0024]
If the result of the determination in step S16 is that the dynamic URL is included in the URL blocking list, the process proceeds to step S34, and the reception of the e-mail is rejected.
[0025]
On the other hand, if the result of the determination in step S16 is that the dynamic URL is not included in the URL blocking list, the process proceeds to step S18, and whether the dynamic URL is the address of a web page registered in the URL passage list (database) is performed. For this purpose, the spam blocking program must operate a URL passage list DB (database).
[0026]
If the result of the determination in step S18 is that the dynamic URL is listed in the URL passage list, the process proceeds to step S32, and the electronic mail is stored in a general mailbox.
[0027]
On the other hand, if the result of the determination in step S18 is that the dynamic URL is not included in the URL passage list, the process proceeds to step S20, and the connection to the web page is made using the dynamic URL.
[0028]
Next, the procedure proceeds to step S22, in which it is determined whether or not the predetermined spam keyword exists in the spam keyword database operated by itself by searching the contents of the connected web page. If it is determined in step S22 that the spam keyword specified in the content of the connected web page is not used, the dynamic URL of the corresponding e-mail is stored in the URL passage list DB (database).
[0029]
On the other hand, if the result of determination in step S22 is that the spam keyword specified in the content of the connected web page still exists, the electronic mail is estimated as spam mail, and the process proceeds to step S24 where the source block list The source of the corresponding e-mail is stored in a DB (database), and the process proceeds to step S26, where the dynamic URL of the corresponding e-mail is stored in the URL blocking list DB (database). Exit after saving to '.
[0030]
Thereby, for example, [Table 1] and [Table 2] below extract a part of the content source of the connected web page (http://www.ohmybuin.com/index.asp?ID=39556623). In the HTML document shown as the above, the spam keywords include “doing friend”, “orgasm”, “adult humor”, “pervert”, “adult novel”, “oral sex”, “sex equipment” or “masturbation”. And the like, and an e-mail having the content of such a keyword could be easily extracted as spam e-mail.
[0031]
Therefore, according to the method for automatically blocking spam mail through the dynamic URL connection of the present invention, after extracting URL information linked to the received e-mail and connecting to the web page, a predetermined spam keyword defined in advance. If there is, spam mail blocking efficiency can be enhanced by extracting this as spam mail and automatically blocking it.
