Description

An E-mail service system with anti-spam mail using virtual E-mail addresses and method therefor}

The present invention relates to a system for preventing spam mail using a virtual email address and a method thereof. In particular, a user sends an email to a counterpart using a virtual email address instead of his or her actual email address, The present invention relates to a spam mail prevention service system using a virtual email address and to a method for receiving only an email sent from a selected sender.

Due to the rapid spread of the Internet, the number of Internet users is gradually increasing, and various Internet services are also becoming common. In particular, the e-mail service is the most basic of the Internet services, which can quickly send a lot of information at a low cost, rapidly replacing the postal system and becoming the most convenient and universal means of exchanging information between individuals. have.

Early e-mails were mainly used for one-on-one communication or communication between individuals, but nowadays individual-group communication or communication is possible because it is possible to reliably deliver information to a specific or unspecified number at low cost. It is also used a lot. Representative examples of such 1: n email transmissions include mailing lists and advertising emails. First, in the case of a mailing list, users form a group by actively subscribing to a service, and form a form of exchanging e-mail within these groups. In addition, in the case of advertising e-mail, a third party acquires e-mail addresses of a plurality of users and delivers the contents intended regardless of the intention of the user. Moreover, more and more companies are now using legitimate or illegal forms of email, as these days the effectiveness of advertising with email is known to be cheaper and more effective than with other media, with anyone having more than one email address. Doing.

Among such advertising e-mails, spam mails are continuously and repeatedly transmitted even if the recipient does not want to send a large amount of indiscriminately advertised e-mail without the recipient's consent. As a result, most of the e-mails delivered to them are often unsolicited e-mails, and as the amount of these e-mails increases more and more, it is more difficult for the user to screen the e-mails that he / she needs. There is a problem that wastes a lot of time.

Early e-mail systems exacerbate this problem by making e-mails delivered to recipients as long as the recipients are accurate, regardless of who the sender is. In response, some attempted to warn or protest by sending an email back through the address of the sender who sent a large amount of spam. However, because the email sender can manipulate the sender's address of the email, sometimes a warning or protest email is delivered to an unrelated person.

Recently, a method of allowing or rejecting only e-mail from a specific sender has emerged, but a method of blocking e-mail from a specific sender is inefficient considering the number of e-mail users around the world. In addition, the sender of spam mail has been deliberately avoided by changing the sender's email address when sending an email. The method of only allowing e-mail from a specific sender may be useful for a user who has a small number of e-mail addresses used, but there is a problem in that a large number of users are not useful when a large list of senders to allow. In addition, as the sender's email address changes, it is inconvenient to constantly add, delete, and change this list.

Therefore, the original method to solve the above problems is to cover up their e-mail address from the third party who do not want and to disclose the e-mail address only to those who need. At this point, it may be safe to disclose your e-mail address to a trusted individual, but nowadays many Internet sites require your e-mail address for informational purposes. It is difficult. As a result, once exposed, his e-mail address information flows to a large number of unspecified masses, causing a lot of advertising e-mails to be sent to the user.

The present invention has been created to solve the above problems, each user to create and use a number of artificial virtual e-mail address whenever necessary to prevent the reception of spam mail and associated with their own e-mail address Its purpose is to help protect privacy.

In addition, the e-mail service method provided through the present invention provides each user with his or her own virtual e-mail address for an untrusted e-mail sender, each user having multiple virtual e-mail addresses. In addition, each time an e-mail is received, the sender for each virtual e-mail address is checked to match the sender already specified, and then the e-mail address information provided once by the third party is obtained by using the e-mail address. It can prevent you from sending spam mails.

The anti-spam email service system using the virtual e-mail address of the present invention for achieving the above object comprises a virtual e-mail address generation unit for generating a virtual e-mail address for a user ID registered in the service, and a user who registers the service. A user information database for storing information about the user, a virtual e-mail address information database for storing information on the virtual e-mail address generated by the virtual e-mail address generator in response to the user ID, and a sent / received e-mail Comparing the address and information stored in the user information database and the virtual e-mail address information database, if the e-mail address sent and received is a valid address, a service control unit and an e-mail authorized from the service control unit for controlling the transmission of the e-mail to the actual user To send / receive Characterized by a portion configured e-mail service.

The anti-spam service method using the virtual e-mail address of the present invention for achieving the above object comprises the first step of inputting a variety of information input from the user to the user information database when the user inputs the service subscription signal, and A second step of generating a virtual e-mail address for the user ID input by the user and storing the virtual e-mail address in the virtual e-mail address information database; and a third step of sending an e-mail to the other party by using the generated virtual e-mail address. And the determination result of the fourth and fourth steps of determining whether the sender and the recipient address of the received e-mail when the e-mail is received from the other party is a valid e-mail address associated with the address registered in the virtual e-mail information database. If it is a mailing address, the email actually uses the virtual email address. Characterized in that the fifth step of transmitting to the party.

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

1 is a schematic configuration diagram of an anti-spam mail service system using a virtual email address according to the present invention.

Referring to Figure 1, the system of the present invention is a virtual e-mail address generation unit 10 for generating a virtual e-mail address for the user ID registered in the service, and sending the user's e-mail using the generated virtual e-mail address; The service control unit 20 controls the transmission of the received e-mail to the actual user by determining the validity of the externally received e-mail, and the user information database 30 storing information on the user who registered the e-mail service using the virtual e-mail address. , A virtual e-mail address information database 40 for storing information on a virtual e-mail address for a user registered in the user information database 30, and an e-mail service unit 50 for transmitting and receiving e-mail with the outside do.

FIG. 2 shows a configuration of the user information database 30 of FIG. 1, which comprises a user ID, a password, a real name of the user, other information, and the like.

3 shows the configuration of the virtual email address information database 40 in the configuration of FIG. 1, which includes a virtual user name (virtual user ID), a real user ID, a valid sender address, a valid recipient address, and other information. Multiple virtual usernames are assigned to one real user ID.

According to the present invention, a process in which a user registers for a service and transmits an e-mail by generating a virtual e-mail address after registration as an embodiment of the present invention may be described as shown in FIG. 4.

First, when a user subscribes to a service using a virtual e-mail address through the e-mail service unit 50, the user undergoes the same registration process as accessing an existing e-mail service. (Step 101). A user ID, which is a unique identifier in the service, is assigned, and simple personal information related to a password and a name for user authentication, and a password for authentication to exercise authority over a corresponding ID are entered (step 102). If the domain name of the e-mail service using the virtual e-mail address is called VirtualMailService.com and a user named 'Waitability' is issued a user ID of 'saturn', the information is displayed in the user information database 30. It is registered with the first line of. The user information database 30 may be further extended in accordance with additional functions of an e-mail service such as a 'forwarding function'. Here, only the configuration of a database related to the core functions of the present invention will be described.

In the state where the actual user ID is registered in the user information database 30 (service registration state) as described above, when the e-mail needs to be transmitted, the user generates a virtual e-mail address for the ID (step 103), The e-mail is transmitted using the virtual e-mail address (step 104). For example, if a user ID 'saturn' is registered in the e-mail service han ***. Com, saturn @ han * The e-mail address using a user ID of **. com is used. However, in the present invention, the e-mail address using the ID registered by the user is not used, but whenever necessary in the virtual e-mail address generation unit 10. A new e-mail address will be generated. As shown in the previous example, when a user registers an ID of 'saturn' with VirtualMailService.com, according to the present invention, the user can use 'saturn @ VirtualMailS' Rather than using an e-mail address using a real user ID of ervice.com, a virtual e-mail address is created using a virtual user name that is generated whenever necessary.

When each user needs to inform his or her e-mail address after registering for an e-mail service using a virtual e-mail address, the virtual e-mail address generator 10 may register a service registered user (a user who has registered a user ID). In step 103, the domain name corresponding to the end of '@' in the virtual email address has already been determined, and thus the virtual user name in front of @ is generated. The virtual email address generator 10 may generate a virtual user name in a free manner within a range that does not exceed international standards related to the email address. In the hex code system, virtual usernames can be generated sequentially, such as '00000000' to 'FFFFFFFF'. Alternatively, one-way hash functions such as third Message Digest Algorithm (MD5) can be used. By using the above-described generated virtual e-mail address, a user can generate a randomly generated virtual address without exposing a real user ID. The e-mail can be transmitted using the e-mail address using the user name. (S104) As described above, a situation in which the user needs to inform his e-mail address can be generally classified as follows. 1) send a personal e-mail to a third party; 2) sign up for a mailing list; and 3) register for an Internet site, and the site requires its own e-mail address.

First, in the case of 1), if the person to whom the e-mail is to be sent is not a trusted person, the virtual e-mail address must be entered in the sender field of the e-mail. For example, if an e-mail is sent to a person with an e-mail address of 'unknown@unknown.com', the service controller 20 requests a virtual user name to be disclosed to a user of 'unknown@unknown.com'. do. Then, the virtual e-mail address generation unit 10 generates an arbitrary virtual user name such as 'P0000000' which allows only an e-mail address user of 'unknown@unknown.com' to send an e-mail. Subsequently, the service control unit 20 generates a virtual email address of 'P0000000@VirtualMailService.com' and inputs an ID, a valid email sender address, and a virtual user name (or virtual email address) as shown in FIG. 3. The information is recorded in the database 40 and then informed to the user. Next, the user enters 'P0000000@VirtualMailService.com', a virtual e-mail address obtained from the service control unit 20, in the sender field of the e-mail, enters 'unknown@unknown.com' in the recipient field, and then e-mails. The e-mail may be sent using the service unit 50 (step 104).

In addition, even when subscribing to the mailing list as shown in 2), the e-mail address provided to the mailing list may be used to send spam mails due to the intention or leakage of the mailing list operator. The e-mail distributed through the mailing list is a characteristic of the virtual e-mail information database 40 because the anonymous majority of the mailing list subscribed to can be a valid mail sender and the address of the recipient address mailing list. The contents may be slightly different from the case of 1). For example, when a user subscribes to a mailing list called 'maillist @ maillist', when the user requests a virtual e-mail address from the service control unit 20, the service control unit ( 20) recognizes only the e-mail whose destination is 'maillist @ maillist' as a valid e-mail, and the virtual e-mail address generation unit 10 receives it. The service control unit 20 generates a virtual e-mail address of 'M0000000@VirtualMailService.com' and generates an ID, a valid e-mail recipient address, and a virtual e-mail address. The user name (or the virtual e-mail address) is recorded in the virtual e-mail address information database 40 as shown in Fig. 3, and the user is informed of this. The user sends a mail through the virtual e-mail address of 'M0000000@VirtualMailService.com'. Subscribe to the ring list.

In addition, as shown in 3), when an e-mail address is required for registration on an Internet site, such a site requires an e-mail address for marketing activities through e-mail. In most cases, it is possible for operators to share their e-mail addresses obtained through this method with multiple providers as needed to send numerous spam emails later. Similarly, if you want to receive a new virtual e-mail address from the system, it is difficult to predict how to fill in the sender and recipient fields of the e-mail when sending e-mail from the Internet site. For example, when a user registers on an Internet site called 'www.shoppingmail.com', the user requests a virtual e-mail address from the service control unit 20, and the virtual e-mail address generation unit 10 sends a sender's e-mail address. Only emails ending in 'shoppingmail.com' are recognized as valid emails. Control the mail address generator 10 to generate an arbitrary virtual username such as 'S0000000' to be received. Then, the service controller 20 generates a virtual email address 'S0000000@VirtualMailService.com'. The ID and the pattern of the valid email sender address and the virtual user name (or the virtual email address) are recorded in the virtual email address information database 40 as shown in FIG. 3, and the user is notified. You can register on the Internet via a virtual email address called 'VirtualMailService.com'.

5 is a flowchart illustrating a process of confirming whether the e-mail is valid when the e-mail is received by the service control unit 20 according to the present invention.

If the user's virtual e-mail address is disclosed to the outside through the above-described operation process, the user expects to receive e-mail only from where the virtual e-mail address information is delivered. Once released, anyone who has obtained the user's e-mail address information can successfully send an e-mail to the user, and therefore not only receive a lot of spam mails, but also a violation of privacy. However, when the e-mail is sent using the virtual e-mail address as in the present invention, the e-mail can be effectively blocked through the operation of FIG. 5 as follows.

First, when an e-mail sent by an anonymous user arrives at an e-mail service system using a virtual e-mail address (step 201), the service control unit 20 checks to which e-mail address the e-mail is to be delivered. Step 202) is distinct from that written in the recipient address (TO: or CC :) column of the MAIL DATA, which is defined by the International Standard for E-mail Transmission, which does not appear in the contents of the email. Appears only on a simple mail transfer protocol (SMTP) between the server and the receiving server ('RCPT TO:' entry), for example, when an email is received via a mailing list maillist@maillist.com. The recipient field in the contents is 'maillist@maillist.com', but because the mailing list is delivered to each user separately, the receiving address on SMTP is M0000000 @ VirtualMailSer The service control unit 20 searches the virtual email information database 30 described in FIG. 3 for the recipient of the email to be delivered by the email sending server. If the address does not exist, the e-mail is rejected (step 203). For example, as shown in FIG. 3, 'M0000000@VirtualMailService.com', 'S0000000 @ VirtualMailService' such as 'P0000000@VirtualMailService.com'. com's three virtual e-mail addresses exist. If an e-mail is sent to an address of 'X0000000@VirtualMailService.com', the service control unit refuses to receive the e-mail.

If the recipient address on the SMTP is a valid recipient address on the virtual email address service, the service control unit 20 reads information on the virtual email address from the virtual email address information database 40. This information contains 1) a valid sender address, 2) a valid recipient address, and 3) a real user ID. The sender address in the header of the contents of the received email is compared with the recipient address field, respectively. If the 'valid sender address' information retrieved from the virtual email address information database 40 has a non-null value, it is compared with the e-mail address written in the sender address field of the e-mail contents (step 204). The sender address' information is recorded in the form of a particular 'sender address' or' regular expression of the sender address'. Accordingly, the service control unit 20 compares the sender address on the e-mail and if there is a mismatch If it is considered that a third party other than a valid sender attempted to send the email, (Step 205) In addition, the 'valid recipient address' information retrieved from the virtual email address information database 40 is similarly compared with the recipient address on the contents of the email (step 206). If all of these comparisons are successful and there is no problem, the e-mail is regarded as a valid e-mail and delivered to the actual user of the virtual e-mail address (step 208).

As mentioned earlier, if the virtual email address'P0000000@VirtualMailService.com is only valid for senders unknown@unknown.com, a third party, e.g. third_party@third_party.com, may use this virtual email. Even if the address is found and sent to the corresponding virtual email address, unknown@unknown.com which is a valid sender address for the virtual email address 'P0000000@VirtualMailService.com' recorded in the virtual email address information database 40 and Inconsistencies will prevent e-mail from being delivered to the actual user. In the case of a mailing list, the sender can be different, so the comparison is done via the recipient's address. For example, a third-party mailing maillist@maillist.com Use this email address information 'M0000000@VirtualMailService.com' from the list to convert this address to a recipient. If you send an e-mail by direct contact, the e-mail's recipient address 'M0000000@VirtualMailService.com' is inconsistent with maillist@maillist.com, a valid recipient address defined on the virtual e-mail information database. Also, if you send a recipient address as another mailing list address, you will be denied e-mail. For example, an email address of 'M0000000@VirtualMailService.com' will be sent to saleslist@sales.com. Is inconsistent with maillist@maillist.com, which is a valid recipient address defined on the virtual email address information database 40, so that the reception of the email is rejected.

If the e-mail is delivered from the last registered Internet site, the e-mail recipient's address may use the virtual e-mail address you provided, or you may create your own mailing list to use this address. If a virtual e-mail address such as 'S0000000@VirtualMailService.com' is provided to the Internet site as shown in Fig. 3, the service control unit expects the sender address in the e-mail content to include the domain name of the corresponding Internet site. For example, if the sender's address is sales@shoppingmall.com, it matches the pattern * .shoppingmall.com, so the email is received by the actual user. However, if another third party, for example, a sender address of sales@other_company.com, sends an email through that virtual email address, the sender address sales@other_company.com is a valid * .shoppingmall.com. Receipt of email to the actual user is rejected because it does not match the recipient address pattern.

If, in the past, you provided a virtual e-mail address so that you could send it to yourself, and you no longer wish to receive the sender's e-mail, you can send a virtual e-mail address information database (without sending the e-mail stop request). By deleting only the relevant virtual e-mail address in 40), it is possible to prevent e-mail reception from the sender, which does not affect other e-mail reception at all.

As such, when a public e-mail address is disclosed using an e-mail service using a virtual e-mail address, most users of the e-mail use such as e-mail transmission between individuals, mailing lists, and e-mails from Internet sites are You can receive only the e-mail you want, block out spam from third parties, and protect your privacy from outside as well as e-mail address information.

As described above, the anti-spam service system and method using the virtual e-mail address of the present invention provides the following effects.

First, it is possible to send an e-mail or provide e-mail address information to an untrusted object through a virtual e-mail address without revealing its actual e-mail address to the outside.

Second, even if a third party acquires the virtual e-mail address information provided by the user, the third party can refuse to receive the e-mails transmitted by the third party.

Third, if it is necessary to receive e-mail from a specific sender allowed in the past, it can be rejected at any time without affecting other e-mail reception.

Fourth, the service user is freed from spam mail and receives only the necessary e-mails, thereby preventing waste of time searching for e-mails, and freely using various e-mails without worrying about privacy related to his e-mail address information. You can implement a service.
