KR20030078979A - The Prevention Method Of SPAM Mail By The Ratio Of Deletions To The Receipt Of A Mail Message - Google Patents

Abstract

PURPOSE: A spam mail interception method is provided to prevent spam mails, transmitted indiscriminately, from coming to a mail box based on a deletion rate of received mails. CONSTITUTION: The method comprises several steps. In a case that there exists an e-mail to be transmitted, a spam mail interception manager(102) parses the body of the e-mail and attached files, and applies a filtering rule to the parsed result for checking whether the e-mail is a spam mail. If the e-mail is a spam mail, the e-mail gets deleted or stored at an advertisement mail box(108), a spam alarm message is transmitted to a mail sender by using a reverse-tracking program(110). Otherwise, the e-mail is transmitted to a mail receiver set by the mail sender. In a case that there exists an e-mail to be received, a spam mail interception agent(122) parses the body of the e-mail and attached files, and applies a filtering rule to the parsed result for checking whether the e-mail is a spam mail. Then, if the e-mail is a spam mail, the mail is filtered and recorded at a deletion box, and the deletion record is transmitted to the spam mail interception manager(102). The deletion rate is calculated in real time. If the deletion rate arrives at a certain level, the manager searches for the corresponding mail in all the mail receiving box of other members, deletes the searched mails, and records the information on the searched mails at the filtering rule for preliminarily intercepting the spam mail.

Description

How to Prevent Spam Mail Based on the Deletion Rate of Incoming Mail {The Prevention Method Of SPAM Mail By The Ratio Of Deletions To The Receipt Of A Mail Message}

The present invention relates to a method for preventing spam mails being sent indiscriminately without the user's consent process by collecting email IDs on the Internet without permission, and more particularly, determination and prevention of spam mails based on the deletion rate of received mails. It's about how

Currently, with the development of the Internet, many people use e-mail as a means of information exchange. In particular, e-mail service as an advertising medium is exploding, and most companies use e-mail as a method of communication with customers in order to secure new customers and maintain loyal customers in terms of customer relationship management (CRM). e-mail) is actively using marketing methods.

However, as the number of mail customers increases on the Internet, some advertisers randomly collect user IDs on the Internet, randomly distributing advertisement mails that users do not want (this is called spam mail), and waste of network resources due to unnecessary traffic. And, the resources of the mail server is wasted, users are annoyed by unnecessary mail flooding. In other words, spam mail is an advertisement e-mail that is unilaterally delivered to a person who has a PC communication or Internet ID. It is also called junk mail, which is delivered indiscriminately to people who have a communication ID. This can waste a lot of time and money reading or processing it.

Therefore, the service providers or solution developers who provide mail services are looking for ways to block spam mails in various ways, but most of them still choose to block them by a specific filtering rule set. Since intelligent spam mail is in full swing, such as changing the mail information so that it cannot be tracked, the original blocking is practically impossible.

The present invention solves the above problems in order to prevent randomly distributed spam mails in advance and minimize the subsequent damages. The purpose is to provide a method for preventing spam mail.

In order to achieve the above object, the method of the present invention, in the situation that the agent for the spam mail blocking agent (Agent) is installed on the user's PC and the server is installed in the anti-spam mail manager (Manager) is installed from the external Internet first Received mail is first blocked by a predetermined filtering rule set in the manager installed at the front end of the mail server, and the mail passing through this is secondarily by the agent when the user receives the mail using the mail client. It is filtered out and blocked.

At this time, the blocking agent (Agent) deletes the blocked mail and the mail information deleted by the user.

The manager is sent to the manager, and the manager checks whether the corresponding mail reaches a deletion rate of more than a predetermined level in real time using this information and determines that the mail is spam. After that, the Manager searches all the recipients of the unreceived mails and moves the mails to the individual advertisement mailboxes, and interlocks with the mail server to prevent the mails from being routed anymore. To reduce the subsequent damage caused. In addition, this spam information is immediately reflected as a rule set of spam mail filtering, characterized in that it is possible to prevent the spam incidents of the same pattern to occur in the future in advance.

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

1 is a system configuration diagram illustrating a spam mail blocking concept according to the present invention.

Referring to FIG. 1, a spam mail sender, a spam mail blocking manager, a mail server Simple Mail Transfer Protocol (SMTP) / POP3 (Post Office Protocol 3), and a spam mail blocking agent located on a user's PC are included. Spammers can generate intelligent spam mail in various ways and send it to the mail server.

In this case, the sent mail is not sent directly to the mail server but is sent to the spam mail blocking manager located at the front end of the mail server. After the manager determines whether the mail is spam with a predetermined filtering rule set, the mail is routed to the mail server. After storing it in the advertisement storage box without routing, the sender traces back and warns the user. The non-spam mail is delivered to the mail server so that the user can receive the mail normally. If not filtered by the manager side, the user is additionally filtered by the spam mail blocking agent when receiving the mail, but the filtering can be circumvented due to the intelligent features of the spam mail.

Therefore, as a core concept of the present invention, a spam determination and an action method based on a deletion rate of received mail, which is a statistical approach, are applied. In other words, when a user deletes an e-mail after receiving it, this information is used to prevent further mail routing by the manager with intelligent blocking function when the deletion rate is reached. Search and reduce the subsequent damage of spam. At this time, in order to guarantee the role and performance of each system, the manager for blocking spam mail operates separately from the mail server for scalability and independence from the mail server.

In the case of webmail, which is generally used, a spam mail blocking agent is included in the webmail function.

2 is a conceptual diagram of an entire system for preventing spam according to the present invention.

If there is a message to be sent, the spam blocking manager 102 determines whether the message is spam by parsing the body and the attached file and applying a predetermined predetermined rule (filtering rule set) 104 to delete if it is spam (106). Alternatively, the advertisement storage box 108 is stored and the traceback program 110 is operated to take a spam warning measure 112, and if the mail is not spam by the filtering method through the mail server 114 through the mail Spool 116. Transfer to user mailbox 118.

When the user receives the mail stored in his or her mailbox 118 (120), the agent 122 parses the body and the attachment file on the agent side by a spam blocking agent 122 installed on the user's PC. By applying a predetermined rule (filtering rule set) 124, whether spam is filtered and moved to the user's deletion box 126 in advance, and the deletion record 128 is transmitted to the spam blocking manager 102. At this time, when the deletion rate reaches a certain level by the deletion statistics in real time, the manager 102 determines that the spam is spam and retrieves all existing recipients' mails and deletes the corresponding mails (130). And prevent further routing of mail (134). In addition, the information is updated and reflected in a predetermined predetermined rule (filtering rule set) 104 so as to be blocked in advance when receiving the same spam mail in the future.

As described above, the present invention effectively removes spam mails and removes them before being sent to the recipient through statistical access by the deletion rate of received mails even for spam mails that are not filtered out.

In addition, the advertisement storage box 108 and the individual advertising mailbox 132 is provided separately to provide a user convenience so that the user can look up the spam mail if desired.

As described above, the present invention effectively removes spam mail that is not blocked by filtering by a statistical approach through interaction with the user by deleting mail, before being sent to the recipient. Therefore, Internet users are automatically protected from the damage of spam mails without having to report spam mails every time, and service providers can prevent waste of system resources due to spam mails and improve the efficiency of their operations, as well as exchange unhealthy data. And it can effectively sanction the spam mail that is the source of the transaction and impose sanctions.
