PORTABLE MEMORY UNIT WITH E-MAIL CLIENT PROGRAM, E-MAIL CONTROL SERVER, E-MAIL SYSTEM WITH THE SAME AND CONTROL METHOD OF THE SAME}

The present invention relates to an e-mail system and a control method thereof, and more particularly, to a method for easily transmitting and receiving e-mail using a removable storage medium and a method for synchronizing information recorded in various mail servers.

Due to the development of the Internet, e-mail systems through the web are becoming more common, and users are rapidly increasing.

The e-mail system sends and receives e-mails through a mail server, and a user operates a service company that provides e-mail services as a way to receive and receive e-mail functions by accessing a mail server. There are two types of methods: accessing a web page and using an e-mail sending / receiving function, and installing a client program that can access a mail server on a computer, and executing a client program to use an e-mail receiving and receiving function.

First, in order to send and receive an e-mail, a user must access a mail server that provides an e-mail sending and receiving function, input and set user information, and receive an e-mail account.

The e-mail transmission and reception method according to the prior art through the web page access after receiving the e-mail account from the mail server as follows.

The user accesses the webpage through the URL (Uniform Resource Locator) of the webpage that provides the e-mail service to a web browser (e.g., Internet Explorer or Netscape), logs in, and uses the e-mail transmission and reception function. .

However, this method is inconvenient to run a web browser, access a web page provided with an e-mail service, and perform a complicated step of logging in. Also, as received e-mail information is stored in a web server, In order to store the information on the user's computer or storage media, there is an inconvenience of having to go through the step of downloading.

In addition, the commercialized e-mail service is exposed to many people, and there is a weak security problem when the ID and password for accessing the web page is leaked.

On the other hand, the client program is a client program provided by Microsoft, for example, Outlook Express (Outlook Express), etc. Looking at the conventional method for sending and receiving e-mail using the client program as follows. .

The user installs a client program (e.g. Outlook Express) on the computer, and sets up information on the e-mail account (e-mail address, password, sending / receiving server name, etc.) received from the mail server to which the user subscribed. Enter it.

When the setting step of the client program is completed, the user executes the client program and accesses a sending / receiving server, that is, a mail server registered in an e-mail account set up through the Internet, and classifies the received e-mail to the mail server as an incoming mail. The electronic mail is stored in a predetermined storage space of the computer, and the e-mail to be transmitted is transmitted through the connected mail server, classified as a transmission mail, and stored in the predetermined storage space of the computer.

However, since the client program is installed and used on a computer, when the user uses a computer other than the computer where the client program is installed and used, the client program is installed on the computer and the e-mail account information of the mail server to be accessed is entered / set. There is an inconvenience to use after.

In addition, even if the client program is installed on another computer as described above and the e-mail account information of the mail server is entered and set, the e-mail already received from the own computer must be downloaded from the mail server to the computer from the beginning. There is discomfort.

In addition, since the synchronization of the mail information already received from the computer is not made, it is inconvenient that the e-mail already received and read from the computer is displayed in an unread state.

In addition, there is a problem that you can not look up information such as address book and calendar registered in its own computer through the client program from another computer.

In addition, mail information sent from its own computer cannot be inquired by another computer, and similarly, in order to store mail information sent from another computer in its own computer, it is inconvenient to move information through a separate storage device.

That is, when using the client program, even if the same mail server is connected and used, there is a problem that mail data information such as incoming and outgoing e-mail, address book, and calendar are not synchronized between computers on which the client program is installed.

 In order to solve this problem, Korean Patent Publication No. 10-2003-0084373 (hereinafter referred to as Reference 1), US Publication 2003/0174167 (hereinafter referred to as Reference 2), and US Patent Publication No. 2004/0199591 (hereinafter referred to) Literature 3) uses the client program to access the mail server and store the received or sent mail data in a USB (Universal Serial Bus) memory for easy movement and management of mail data. Since the mail data stored in the USB memory is used every time, the mail data information is synchronized.

The e-mail system includes a control server 1000 for controlling the system according to the present invention, a terminal 2000 such as a desktop computer 2100 connected to a network and operable by a user, a laptop 2200, or a mobile communication terminal 2300. ), A storage medium 3000, and a mail server 4000.

In this case, the storage medium 3000 may be a storage space included in the terminal 2000 or may be a separate USB memory or a removable storage medium such as a DVD that can be read and written.

That is, when the storage medium 3000 is a storage space of the terminal 2000, the storage medium 3000 may be a hard disk included in the desktop computer 2100 and the notebook 2200, and also included in the mobile communication terminal 2300. It may be built-in memory or external memory for expansion.

In the following description of the present invention, a USB memory is described as the storage medium 3000 by way of example, but is not limited to the USB memory.

As a storage medium 3000 according to the present invention, a USB memory is connected to a network terminal to store a USB connector 3300 for transmitting and receiving signals, a controller 3200 for controlling the overall operation of the USB memory device, and storing data information. It is configured to include a memory unit 3100.

The controller 3200 may be referred to as a main control unit (MCU) and controls a process for data input / output with the terminal 2000 and recording and deleting of data to the memory unit 3100 through the USB connector 3300.

The memory unit 3100 checks the public area 3140 that all users can access and the password so that the private area 3120 that only a specific user can access and the hidden areas that all users cannot access. When the region 3110 and the USB memory are inserted into the USB port of the terminal, an auto run region 3130 for allowing a program preset by the controller 3200 to be automatically run and plugged in the terminal. It is configured to include.

The autorun region 3140 is automatically executed in the terminal when the removable storage medium is inserted into the terminal, and then includes the authentication program 3131 for the authentication procedure described with reference to FIGS. 3 to 4.

The hidden area 3110 compares an ID number and a password inputted by a user by the ID number of the USB memory device, which is a removable storage medium, that is, a storage medium ID number 3111, and the authentication program 3131, to use the client program 3123. It includes a program ID / password (3113) for authentication.

The private area 3120 includes mail data information 3121 including mail data, address book data, calendar data, and the like, which are connected to and received from a mail server, and mail servers such as addresses of mail servers, accounts and passwords of the mail servers ( E-mail account information 3122, which is information for accessing 4000, and a mail client program 3123, which is loaded into the terminal by a call of the terminal and executed in the terminal.

3 is a block diagram showing an authentication procedure according to an embodiment of the present invention.

First, a USB memory that is a removable storage medium 3000 is connected to a USB port included in the terminal 2000.

The terminal 2000 is a plug and play program supported by the controller 3200 of the USB memory or a user transmits an execution command (step S1210) through a mouse or a keyboard in the terminal 2000, and a storage medium. The control program included in the terminal 2000 is called by the controller included in the terminal 2000, loaded into the memory included in the terminal 2000, and executed (S1220).

The authentication program executed in the terminal 2000 calls the storage medium unique value 3111 stored in the storage medium 3000 and transmits the storage medium unique value 3111 to the control server 1000 (step S1230). .

The control server 1000 compares the storage medium unique value 3111 received from the terminal 2000 with the available unique values stored in the storage included in the control server 1000 to determine whether the authentication is possible. In the case of the non-authenticated storage medium intrinsic value 3111 (step S1110), the display device included in the terminal 2000 is determined to be unavailable (step S1120) and transmits a signal corresponding to the terminal 2000. Inform the user that authentication has failed (step S1240), and if the unique value of the storage medium 3111 authenticated in the authentication step (step S1110) is determined to be used (step S1130) through the terminal 2000. Make the client program available.

When the terminal 2000 receives an authorization from the control server 1000, the terminal 2000 loads and executes the client program 3123 stored in the storage medium 3000 in a memory included in the terminal 2000 (S1250).

In this case, the available unique values stored in the storage unit included in the control server 1000 may be registered for use of the storage medium 3000 in the control server 1000 before the user uses the storage medium 3000 for use of the storage medium 3000. It is preferable to store the unique value of the storage medium entered by the user during the registration process.

Therefore, when the user loses the storage medium 3000, the user who has acquired the lost storage medium 3000 by using the storage medium unique value registered in the control server 1000 stops using the information contained in the storage medium or the mail server. And the like can be prevented from acquiring mail data information.

4 is a block diagram showing an authentication procedure according to another embodiment of the present invention.

As in FIG. 3, first, a USB memory, which is a removable storage medium 3000, is connected to a USB port included in the terminal 2000.

The terminal 2000 is a plug and play program supported by the controller 3200 of the USB memory or a user transmits an execution command (step S2210) through a mouse or a keyboard in the terminal 2000, and a storage medium. The control program included in the terminal 2000 is called by the controller included in the terminal 2000, loaded into the memory included in the terminal 2000, and executed (S2220).

The authentication program executed in the terminal 2000 displays a window for inputting an ID (ID) and a password (PW) set to use the client program on the display device included in the terminal 2000. In the input window (step S2230).

In this case, the authentication program to be executed in the terminal as a first method is compared to the ID and password entered by the user through the terminal and the ID and password 3113 stored in the hidden area 3110 of the storage medium 3000 ID It is determined whether and the password match (step S2240).

If the ID and password entered by the user through the terminal 2000 and the program ID and password 3113 stored in the storage medium 3000 do not match in step S2240, the input ID and password do not match. The user is guided through the display device included in step S2250, and the user returns to the step ID2 and password input step S2230 to allow the user to input the ID and password again.

In step S2240, if the user ID and password inputted through the terminal 2000 and the program ID and password 3113 stored in the storage medium 3000 match, the client program can be used through the terminal 2000. do.

The terminal 2000 loads and executes the client program 3123 stored in the storage medium 3000 in a memory included in the terminal 2000 (step S2260).

The user accesses, records, and accesses mail data information 3121 and e-mail account information 3122 stored in the private area 3120 of the storage medium 3000 using a client program executed in the terminal 2000. You can delete it.

That is, according to the first method, even when the terminal is not connected to the network, the user accesses, records, and deletes the mail data information 3121 and the e-mail account information 3122 stored in the storage medium 3000. You can do

In the second method, the authentication program executed in the terminal 2000 transmits the ID and password input by the user to the control server 1000, and the control server 1000 is stored in the storage of the control server 1000. It is determined whether the program ID and password that is present and the ID and password received from the authentication program executed in the terminal 2000 is the same (S2110).

If the ID and password entered by the user through the terminal 2000 and the program ID and password stored in the storage of the control server 1000 do not match in step S2110, the input ID and password do not match. The server 1000 transmits the information to the terminal 2000, and the authentication program executed in the terminal 2000 guides the user through a display device included in the terminal 2000 based on the signal received from the control server 1000. In step S2250, the user returns to the user ID and password input step (S2230).

When the user ID and password input by the user through the terminal 2000 and the program ID and password stored in the storage of the control server 1000 in step S2110 match, the client program can be used through the terminal 2000. do.

The terminal 2000 loads and executes the client program 3123 stored in the storage medium 3000 in a memory included in the terminal 2000 (step S2260).

The user may use a function of a client program executed in the terminal 2000, and may use a function provided by the control server 1000, such as exchanging information with the control server 1000, which will be described later.

In addition, although the first method and the second method have been described separately, the first method and the second method may be implemented together as shown in FIG. 4.

In addition, although the authentication method by the unique value of the storage medium described with reference to FIG. 3 and the authentication method by the ID and password described with reference to FIG. 4 have been separately described, each method may be used together, and If described below as an embodiment as follows.

First, in step 3, the client program execution step (step S1250) is deleted, and whether the authentication of the storage medium intrinsic value 3111 is authorized (S1110). When the use is authorized (step S1130), the terminal 2000 of FIG. ) May be used in combination after the step of inputting the ID and password (step S2230).

In addition, the client program execution step (step S2260) is deleted in FIG. 4 and the terminal 2000 determines whether the ID and password match (step S2240), or the control server 1000 determines whether the ID and password match. (S2110) and if it is determined that they match, the terminal 2000 of FIG. 3 receives the storage medium unique value 3111 stored in the storage medium 3000 and transmits the storage medium unique value to the control server 1000 ( It is also possible to use a combination of the steps after step S1230).

Accordingly, even if a user loses the storage medium 3000, particularly a removable storage medium such as a USB memory, according to various connection authentication procedures according to the present invention described with reference to FIGS. 3 to 4, the storage medium 3000 is lost in the control server. By inputting the lost information, the security function is improved so that a person who acquires the lost storage medium 3000 cannot query information included in the storage medium 3000.

5 is mail data information such as mail data, address book data, and schedule management data received from a mail server 4000 to be connected after the use of a client program is authenticated by the authentication method described with reference to FIGS. 3 to 4. A block diagram for explaining a method according to an embodiment of the present invention to collect a.

The client program executed in the terminal 2000 reads the e-mail account information 3122 stored in the private area 3120 of the storage medium 3000, and the mail server 4000 to which the client program is to be connected establishes a connection method using the protocol. It is determined whether to support (step S3210).

At this time, the e-mail account information 3122 is an account type of the mail server 4000, that is, a supported protocol (such as POP3 or SMTP), an incoming mail server address, an outgoing mail server address, and an email address given from the mail server 4000. And a user ID and password, and the e-mail account information 3122 is configured to include the above-mentioned information about the mail server when there are a plurality of mail servers to be accessed.

Therefore, in step S3210, by determining the account type of the mail server 4000 to be accessed from the e-mail account information 3122 stored in the storage medium 3000 or received from the storage medium 3000, POP or SMTP is determined. In the case of a mail server that does not support such a protocol, web crawling is performed using the registered receiving or sending mail server address (step S3230) to collect mail data information (step S3240).

Here, web crawling is a technology that collects information by accessing a page (e.g. web page) corresponding to a registered address and a page (e.g. web page) linked to it, when it is difficult to connect to a database by connecting to a server. This technique is mainly used to extract the desired information by analyzing html source and the information displayed through the page.

In addition, in step S3210 by determining the account type of the mail server 4000 to be accessed from the e-mail account information 3122 stored in the storage medium 3000 or received from the storage medium 3000, POP or SMTP is determined. In the case of the mail server 4000 that supports a protocol such as the above, the client program executed in the terminal 2000 delivers the e-mail account information 3122 for accessing the mail server 4000 to the mail server 4000. Request mail data information (step S3220).

The mail server 4000 transmits the mail data information requested by the client program to the terminal 2000 on which the client program is executed (step S3410).

That is, a method of connecting to a mail server and collecting mail data by a protocol can be implemented similarly to a method by a client program such as Microsoft Outlook installed in a terminal according to the prior art.
