The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a configuration of an embodiment of a hybrid postal delivery system using the web according to the present invention.

The present invention transmits various types of electronic documents created by Internet users using various application software to the Internet electronic mail server of a post office through the Internet in a web manner. The server then uses the recipient's postal information to electronically select and transmit the post office closest to the recipient, and the receiving post office delivers the electronically received message to the final recipient in the same way as normal mail. .

When the sender creates a mail and sends it to the web server 12 via the Internet, the web server 12 uses the sender information (postal code, etc.) to obtain an internal post office e-mail address to which the mail should arrive, which is then sent to the preprocessing station (11). Send to)

When the preprocessing station 11 obtains the post office e-mail address in the jurisdiction, the preprocessing station 11 generates a message according to the Multi-purpose Internet Mail Extension (MIME) protocol for the mail written by the sender, and the sender sends the MIME message to the certificate authority (16). After signing using the signature secret key received from the), create a control body as shown in Figure 5, create a MIME message, and create a whole mail (content body + control body + mail header) including the content body and the mail header. It is sent to the web server 12 in a protocol called HyperText Transfer Protocol (HTTP).

The CGI program of the web server 12 has routing information based on the postal code, and can use this to generate an e-mail address corresponding to the postal code of the recipient. That is, the routing information stores one e-mail address assigned to all post offices and a postal code to be processed by each post office. The mail received from the web browser is transmitted to the mail server 15 using a protocol called Simple Mail Transfer Protocol (SMTP).

The program installed in the post-processing station 14 brings the mail sent to its own post office from among the mails arriving at the mail server 15 using a protocol 401 called Post Office Protocol 3 (POP3). The post processing station 14 analyzes the contents of the received mail and checks the forgery / falsification of the content body by using the sender's signature public key. Print and enclose the address and contents of the and the sender. This is delivered to the recipient via postman.

2 is a flow chart of an embodiment of a hybrid postal delivery method using the web according to the present invention.

The preprocessing station receives the sender information, the receiver information, the mail content, and the mail type from the sender (201), and if the sender selects the transmission method as the content verification service, receives the certificate and the signature key from the sender (202). ).

The preprocessing station then first sends the recipient's postal code to the web server (203).

When the web server finds an e-mail address of the post office in the jurisdiction corresponding to the postal code of the recipient and transmits the e-mail address to the preprocessing station again (204), the preprocessing station generates a MIME message based on the e-mail address and delivers it to the web server (205). .

When the web server transmits the MIME message received from the preprocessing station to the mail server using the SMTP protocol (206), the mail server stores / manages the MIME message (207).

The post-processing station installed at the post office in the recipient's office always checks the mail server for mail using the POP3 protocol, receives the mail from the client, analyzes it, and sends it to the recipient (208).

3 is a flow diagram of an embodiment of the function of the front agent of FIG. 1 in accordance with the present invention.

The preprocessing station 11 transmits only the recipient information of the mail contents created by the sender to the recipient through the user interface to the web server 12 (301).

After that, when the preprocessing station 11 receives the intra-office post office e-mail address to which mail should arrive from the web server 12 (302), the preprocessing station 11 generates a MIME message for the contents of the mail prepared by the sender (303). That is, it creates a content body MIME. If the type of the mail is the content confirmation mail, the content body MIME is signed using the signature secret key received by the sender from the certification authority (304).

Then, as shown in FIG. 5, a control body (FIG. 5) including a mail service type, sender information, recipient information, electronic signature result, and sender certificate is created (305). This control body is made into a control body MIME (306), and an entire mail is generated including the content body MIME (see FIG. 6), and sent to the web server 12 in HTTP protocol (307). Here, the electronic signature result and the sender certificate are included in the control body only in the case of the content confirmation mail.

4 is a flow diagram of one embodiment of the functionality of the end agent of FIG. 1 in accordance with the present invention.

The post-processing station 14 brings the mail sent to its internal post office from among the mail arriving at the mail server 15 using the Post Office Protocol 3 (POP3) protocol (401). The post processing station 14 analyzes the mail content brought by the mail analysis unit through the POP3 protocol, and extracts the content body and the control body (402).

The control body is analyzed to confirm the type of mail (ie, normal mail, arrival confirmation mail, or content confirmation mail) (403).

Here, the normal mail is mail delivered by a user to a post office closest to the recipient through the Internet, printed on the post office, and then delivered to a non-computer recipient through a postman, upon arrival. A mail is usually an arrival confirmation function, such as a registered mail, in a normal mail. A content confirmation mail usually means that the sender and the content have not been changed in the normal mail. It proves the sound.

If the verification result is the content confirmation mail, extract the sender's and receiver's information (name, address, postal code) from the control body (405), obtain the sender's certificate included in the control body, and find out which organization issued the certificate. After obtaining from the certificate (406), the forgery / falsification of the certificate is checked using the signed public key of the issuing certification authority, and if the forgery / falsification is not done, the validity period of the certificate is checked (407).

Then, using the sender's signature public key included in the certificate, the forgery / falsification of the content body is checked (408). If the forgery / falsification is not done, the recipient and the sender's address and The content is printed (409) and enclosed, and then delivered to the recipient through the postman (410). On the other hand, if forgery / falsification is confirmed, it is notified to the sender.

If the verification result is a normal mail or arrival confirmation mail, after extracting the sender and recipient information (name, address, postal code) from the control body (404), the existing mail without certificate and signature verification procedure unlike the content confirmation mail After printing (409) the address and contents of the recipient and the sender on a sheet of paper that can be enclosed in an envelope, the package is enclosed and delivered to the recipient through a postman (410).

In the case of the mail of arrival confirmation, there is a process in which the postman receives the postal confirmation from the receiver, but this is not directly related to the present invention.

FIG. 5 is a block diagram of an embodiment of a control body generated in the preprocessing station according to the present invention.

The control body includes a mail service form (usually mail, arrival confirmation mail, and content confirmation mail), sender information, recipient information, digital signature result, and sender certificate, which is generated by the preprocessing station. Here, the electronic signature result and the sender certificate are included in the control body only in the case of the content confirmation mail.

6 is a diagram illustrating an embodiment of an e-mail form generated by a preprocessing station according to the present invention.

The preprocessing station 11 combines the contents 603-605 of the control body 606 of FIG. 5 with the mail header 602 to produce the entire mail 601.

Thereafter, the entire mail 601 is transmitted to the post-processing station 14 through the web server 12 and the mail server 15 using the HTTP protocol. The method of the present invention as described above is implemented as a program. The data may be stored in a computer-readable form on a recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.).

The present invention described above is capable of various substitutions, modifications, and changes without departing from the spirit of the present invention for those skilled in the art to which the present invention pertains, and the above-described embodiments and accompanying It is not limited by the drawings.

As described above, the present invention can transmit various kinds of data quickly and accurately and at low cost through a conventional post office system using the Internet, and can reduce logistics costs by minimizing a message delivery path, and also by mail. It is effective to check whether the contents have been tampered with.
