The present invention relates to a spam mail processing device and method for performing a technology for processing spam, in particular, to resend the spam mail or change a spam rule according to a user's request that the spam mail is stored, and this method. It relates to a recording medium recording a program for executing.

E-mail services, which are the first to be used on the Internet and are still the most active, are exploding each year. In particular, as the e-commerce through the Internet becomes active, a large number of e-mails are sent indiscriminately to specific recipients, resulting in an explosive increase in e-mail transmissions. The economic damage caused by the increase of the capacity of the e-mail server and the user who uses the e-mail service are suffering from the mental damage that must receive unnecessary commercial advertisement regardless of the doctor. This unsolicited and unsolicited mail is often referred to as spam or junk mail (hereinafter referred to as spam mail).

However, increasing the capacity of an e-mail server indefinitely cannot be a fundamental solution to spam mail, and some spam mails are designed to prevent users from unsubscribing. Was done.

These spam blocking solutions are largely classified into a 'server solution' installed on top of a mail server to search for e-mails sent to the mail server, and a 'client product' installed on each user's computer to check mailboxes. Most of the technology is based on so-called message filtering. Message filtering is a technology that blocks certain words or messages when they are included in the header, subject, body, and attachments that record various information of the mail as spam mail.

In addition, when the same e-mail sender sends excessive mail for a certain time, a technique of tracking the sender's IP and subsequently blocking the mail sent from the IP as spam is well known. In addition, techniques for preventing e-mail extraction, which disables the function of the software for extracting e-mail, and techniques for blocking spam mail using a virtual e-mail account are known.

6 shows a conventional spam mail blocking system. According to FIG. 6, the e-mail including the spam mail and the normal mail is blocked by the spam mail monitoring means 601 before it arrives at the mail server 602, and only the normal mail passes through the mail server 602. 603).

However, the conventional spam mail blocking technology blocks e-mails corresponding to the spam rules set by the e-mail service provider or the user before reaching the mail server or the user, so that the user may not receive the e-mail actually desired. There is a problem. For example, in the filtering of a message, a spam rule that recognizes and blocks an e-mail containing the word "ad" in the subject of an e-mail is blocked. Since the e-mail containing the subject of the e-mail is also blocked, the user has a problem that can not receive the information necessary for him.

Accordingly, an object of the present invention is to provide a spam mail processing apparatus and method for storing spam mails and resending spam mails selected by a user's request as normal mails or deleting true spam mails. It is to solve the above problems with the spam mail blocking technology.

In addition, another object of the present invention, by providing a spam mail processing apparatus and method that can send a list of pre-stored spam mail to a user at a predetermined time, so that it is more convenient to check the e-mail required by the spam mail It is.

(First embodiment)

1 illustrates a spam mail blocking system including a spam mail processing device according to an embodiment of the present invention. According to FIG. 1, the spam mail processing apparatus 10 includes a spam mail managing means 102, a spam mail DB 104, a spam mail monitoring means 106, and a spam rule DB 108.

The spam mail monitoring means 106 classifies the spam mail and the normal mail from the received e-mail 40, and sends the normal mail to the user computer 30 through the mail server 20, and the spam mail is the spam mail DB 104. ). Spam mail DB 104 is where the e-mail classified as spam in the spam monitoring means 106 is stored.

The spam rule DB 108 is where the spam monitoring means 106 stores data on criteria for classifying spam and normal mail. According to FIG. 2, the spam rule DB 108 includes a user-only spam rule DB 202 and an administrator-only spam rule DB 204.

The user-specific spam rule DB 202 stores information on spam rules in the form of a file, and this file is assigned to each user. 3 illustrates a spam rule file structure of a user having an ID of 'test'.

According to FIG. 3 (a), a file named 'test.spamcf' is assigned to a user having an ID of 'test', and this file has a spam rule version, a main spam rule applying switch, a spam rule applying level, and a user registered. It contains information on the maximum possible number of spam rules and user-registered spam rules. The spam rule version is the version information for the spam rule, and the spam rule application switch indicates whether or not the entire spam rule is applied. If this information is off, the user (regardless of the application of each spam rule to be described later) All spam rules for test will not be applied.

Spam rule application level is the system rule information that the user wants to apply among the system rules set by the administrator in advance. For example, when the system rule is provided as shown in FIG. News] If you need to receive an e-mail titled 'OO High School Alumni', you will choose the system rule at level mid because the level high system rule will not be applied. In this case, the spam rule is applied only at the lower level of the set level. Therefore, the spam rule to be applied to the user 30 will be level mid and level low. Therefore, e-mail with the word "ad" in the subject at level low will be deleted, and e-mail with the word "information" in the subject at level mid will be spam. It will be stored in DB 104 (save spamdb).

The information on the maximum number of spam rules that can be registered by the user is a value that can be set only by the system administrator and indicates the maximum number of spam rules that can be registered by the user.

Meanwhile, the information regarding the user registration spam rule is composed of the same information as in FIG. 3 (a) (hereinafter referred to as 'spam rule information'), and the spam rule information includes a spam rule name and an application switch of the corresponding spam rule. , Sub-spam rule combination method, spam processing method, spam rule application item, spam rule application method and spam pattern. Also, among the spam rule information, the spam rule application item, spam rule application method, and spam pattern constitute spam pattern information, the spam pattern information is a spam rule of sub-condition applied to the spam rule, and the spam rule information is one or more spam. It may include pattern information.

The switch for applying the spam rule is information on whether the spam rule is applied separately from the switch for applying the main spam rule. That is, it is a lower switch of the main spam rule application switch. Therefore, as described above, the application switch of the corresponding spam rule is valid only when the main spam rule application switch is ON. If the main spam rule application switch is OFF, the application switch of the corresponding spam rule is ON. The spam rule does not work, whether it is on or off. The combination method of the lower spam rules is information on how the spam patterns to be described below are combined, and may have information such as OR or AND. The spam processing method may delete e-mail to which the spam rule is applied or spam mail. Information on whether or not to store in the DB 104, the spam rule application item is information on the item to which the spam rule is applied, such as the subject / sender / body, etc., the spam rule application method is to include / start / end / include with the spam rule Information about when the spam rule is applied, such as when / matched.

FIG. 3 (b) shows specific file information included in test.spamcf of FIG. 3 (a). According to FIG. 3 (b), the spam rule set for the user 30 having an ID of 'test' has a version (VERSION) of 1.0, the main spam rule applying switch (APPLY) is OFF, and a spam rule application level. (SYSTEM_RULE_LEVEL) is mid, the maximum number of user-registerable spam rules (MAX_USER_RULE) is 100, and test.spamcf includes a user-registered spam rule named RULE_testrule1. In this embodiment, only one registered spam rule called RULE_testrule1 is described. However, since the maximum number of registered spam rules is 100, the test.spamcf file may include user-registered spam rules up to RULE_testrule100.

Meanwhile, according to the spam rule information illustrated in FIG. 3 (b), the spam rule application switch of RULE_testrule1 is ON, the combination method of the spam pattern information is OR, and the spam pattern corresponding to the spam pattern information is deleted (DELETE). ), The spam rule information has three spam pattern information. Therefore, assuming that the main spam rule application switch (APPLY) is ON, it has a pattern of 'test' from the beginning of the subject (START) (OR) or 'tester' in the sender (FROM). E-mail containing CONTAIN (OR) or subject (SUBJECT) matching the pattern (testACT) (EXACT) is considered spam and deleted (DELETE).

The user-only spam rule DB 202 is a DB to which the user is allowed access, and as described below, the spam management means 102 is allowed to access the spam rule when the user wants to change the spam rule.

In addition, although the administrator-only spam rule DB 204 is not specifically described in this embodiment to avoid blurring the features of the present invention, the administrator is a spam mail processing device 10 and a mail in an area where the user is not allowed access. The person in charge of the management of the server 20. Therefore, even if the description of the administrator is omitted, the only way that the administrator has access to the spam mail processing device 10 is different from that of the user 30. It will be readily understood by one skilled in the art to which the present invention pertains that the way of approaching 30) is no different. Therefore, the administrator-only spam rule 204 is not allowed to access the user 30, and only an administrator can access and change a spam rule.

The spam mail managing means 102 provides a function of recovering spam mail or changing spam rules according to a request of the user 30. According to Figure 4, spam management means 102 is composed of a spam mail processing means 402, spam rule changing means 404 and notification mail request transmission means 406.

Spam mail processing means 402, if there is a request for inquiry to the spam mail DB from the user 30, the spam mail management means 102 is a spam mail DB 104 to the spam mail assigned to the user (30) Is sent to the user 30, and if the user 30 determines that the message is not true spam and requests resend for the selected spam mail, the resend request is sent to the spam monitoring means 106, or the user is a true spam. When it is determined that the mail is requested to be deleted for the selected spam mail, the selected spam mail is deleted.

In addition, the spam rule changing means 404 provides the user 30 with a spam rule file assigned to the user 30 in the user-specific spam rule DB 202 when there is a spam rule change request from the user 30. The user 30 may arbitrarily change the spam rule, and if there is a spam rule change request from the administrator, the administrator may provide the administrator with a dedicated spam rule DB 204 so that the administrator may change the spam rule arbitrarily.

In addition, the notification mail request transmission means 406 notifies the user 30 to send a notification mail including a list of spam mails assigned to the user 30 at a predetermined time when the user 30 requests. The mail transmission request is transmitted to the spam mail monitoring means 106. In addition, the spam mail monitoring means 106 may transmit the notification mail every predetermined time whether or not the user 30 requests. The predetermined time may be set to, for example, one day (24 hours).

Next, the operation according to the present embodiment will be described below.

When the e-mail 40 to be received through a network such as the Internet is received by the spam mail processing device 10 before being transmitted to the mail server 20, the spam mail monitoring means 106 refers to the spam rule DB 108. Thus, the normal mail is transmitted to the mail server 20, and the spam mail is transmitted to the spam mail DB 104 and stored in the e-mail 40. Subsequently, the normal mail is transmitted from the mail server 20 to the user 30 at the request of the user 30.

On the other hand, the user 30 may access the spam management means 102 to perform a predetermined process for the spam mail and spam rule DB, in this embodiment the user directly connected to the spam mail processing device 10 Although described as being for convenience of explanation, in practice, a web server providing a specific web page to the user 30 may be interposed between the device 10 and the user 30, and the device 10 may be a web server. It can be understood that it forms some component of. Therefore, in this embodiment, it can be understood that the spam management means 102 performs an interface with the user 30 through the provision of a website.

The user 30 connected to the spam management means 102 can request a spam inquiry to the spam management means 102, in which case the spam processing means 402 of the spam management means 102 is a user. The spam mail assigned to 30 is taken out of the spam mail DB 104 and shown to the user 30. When the user 30 requests the spam mail processing means 402 to select one of the spam mails to be sent to the mail server 20, the spam mail processing means 402 sends the selected spam mail to the mail server. And the spam mail is deleted for the spam mail requested by the user 30 to be deleted.

In addition, when the user 30 makes a spam rule change request to the spam rule changing means 404, the spam rule changing means 404 is shown in FIG. 3 assigned to the user 300 in the user-only spam rule DB 202. By providing the user 30 with a spam rule file containing the information as shown, the user 30 can change the spam rule. When the administrator makes a spam rule change request to the spam rule change means 404, the spam rule change means 404 shows the spam rule included in the administrator-specific spam rule DB 204 to the administrator to change the spam rule. To be able.

On the other hand, if the user 30 wants to check the spam mail assigned to him without accessing the spam mail processing apparatus 10, he connects to the notification mail request transmission means 406 of the spam mail management means 102, When the notification mail transmission request and a predetermined time are set, the spam mail monitoring means 106 transmits the notification mail to the user 30 through the mail server 20 at the predetermined time. Therefore, the user 30 has an advantage of checking the spam mail through the mail server 20 without directly accessing the spam mail processing apparatus 10. In addition, even if the spam mail monitoring means 106 transmits the notification mail to the mail server 20 every predetermined time regardless of the user's request.
