Like reference numerals in the drawings refer to the same or similar functions throughout the several aspects.

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

Existing e-mail (e-mail) is a service that can be provided by any Internet service provider and can be used easily and conveniently when distributing information / documents between individuals, between companies, and between individuals and companies. There are risks of forgery / modulation, transmission error, spam mail, etc., and it is difficult to prove in case of outgoing / receiving dispute between parties.

1 is a conceptual diagram showing a delivery process of a conventional e-mail (e-mail).

E-mail (e-mail) is the sender's a) Web Mail service (e.g., Naver mail, Daum mail, etc.) or e-mail Client (such as Microsoft's Outlook), b) the mail server used by the sender. SMTP (Simple Mail Transfer Protocol) service, c) Domain Name System (DNS) server, d) POP3 (Post Office Protocol 3) service used by the recipient, e) Recipient's Web Mail service or e-mail client. And arrive at the recipient. On the other hand, POP3 has the disadvantage of not being able to check e-mails downloaded to PC once by e-mail client of other PCs. Nowadays, it supports IMAP (Internet Mail Access Protocol) service, which supplements this and saves all e-mails in the server first. Most mail servers do.

The public e-mail address (shop mail) is provided with a content proof function to ensure authentication and non-repudiation of the e-mail sender / receiver user.However, unlike the existing e-mail using the SMTP (Simple Mail Transfer Protocol) communication protocol as a standard, ShopMail uses the Hyper Text Transfer Protocol (HTTP) and ebXML Messaging Service Specification (ebMS) protocols as standard, and the address system / authentication system is different, so it is not compatible with existing e-mail accounts, so you need to create a shop mail account separately. Due to the hassle and difficulty of distributing electronic documents only between shopmails, it has not been activated even five years after the service was introduced in December 2012. It is too government-led, over-regulated, and internationally isolated. It is also criticized for deepening.

2 is a conceptual diagram illustrating a registration system of a public electronic address (shop mail).

There is a registration management institution (KISA) of the official electronic address (Shopmail), and there is a registration agency (certified electronic document relay) that performs registration-related work under the subsidiary. You must use the service after registering Shopmail.

3 is a conceptual diagram illustrating a sending / receiving process of an authorized electronic address (shop mail).

In order to send / receive electronic documents using a certified electronic address (shop mail): a) The homepage or mobile of the registered agency (certified electronic document relay) where the user registered / subscribes his / her certified electronic address (shop mail). Access by using the App, or b) install the software provided by the registration agency (certified electronic document relay) to access the client installed on the PC, or c) register the shopmail server after the company has built its own It can be used in connection with the shop mail server of an agency (certified electronic document relay).

In addition, the Registration Agency (Korea Internet Security Agency, KISA) is an electronic document distribution hub, and is responsible for registering / retrieving / canceling authorized electronic addresses, relaying, blocking spam, keeping distribution information, and issuing distribution certificates.

On the other hand, among the postal services, services to clarify the facts in the mail delivery process, there are three proof services of content verification, delivery certification and receipt time certification. 'Certificate of content' is a system whereby the post office publicly certifies that the sender sent a document to the addressee when and when it is necessary to leave the contents of the mail as proof of the future. It is often used in conjunction with a 'delivery certificate' to confirm the fact that mail is delivered to the recipient. 'Proof of Delivery' is a system that proves the delivery date, delivery date and recipient at the post office. 'Receipt time certification' is a system that displays and proves the time of receipt of mails received by the sender on the mail. It is often used when the time of submission of documents, etc. has a significant effect on the acquisition of rights.

Recently, there is a service that allows users to access the homepage of the Internet post office and send 'content proof' without visiting the post office, but it is not activated.

Proof e-mail service method and apparatus according to an embodiment of the present invention is proposed to solve these problems, anyone can use easily and conveniently. In addition, identity verification and non-repudiation, forgery / falsification, and information leakage prevention and proof (e.g., proof of contents, proof of delivery, proof of time of transmission) on e-mails (e-mails) that cannot guarantee the safety and reliability of sending / receiving. By enabling verification, individuals and corporations can securely and conveniently send / receive electronic documents and be guaranteed legal validity.

Proof e-mail service method and apparatus according to an embodiment of the present invention is based on the convenient and open delivery process of the e-mail (e-mail), but applying the registration system and sending / receiving process of the official e-mail address (shop mail) By implementing a new electronic document distribution system, the convenience and openness of the e-mail (e-mail), and the security, identity verification, non-repudiation function, and legal effect such as the advantages of the public e-mail (shop mail) are secured. Can provide.

Referring to FIG. 5, a sender may request to send an attestation e-mail through the user device (step S500).

The sender is an attestation that includes one or more content documents (text and attachments) and sender and recipient (and referrer) information to his or her email service provider through the web mail service or email client used by the sender. You can request to send an e-mail.

Sender and recipient (and referrer) information may include name, e-mail address, mobile phone number, etc., and in some cases multiple recipients (and referrers). In step S500, the attestation e-mail service may be provided by the company service server provided with the client provided by the mail service provider server or provided by the mail service provider server. For convenience of explanation, it is assumed that the proof e-mail service is provided by the mail service provider server.

In the embodiment of the present invention, the description is made on the assumption that the attached document of the content document is an electronic document. However, the attached document may mean attached information, and the attached information includes various multimedia data such as a video and audio in addition to the electronic document. can do.

The sender mail service provider server that provides the proof email service to the sender can check whether the recipient (and the reference person) can receive the proof email (step S510).

The recipient device of the recipient (and the reference person) who wants to receive the proof email sent by the sender's sender device can determine whether or not the receipt email can be received.

That is, the sender mail service provider server associated with the sender device can check whether there is a recipient mail service provider server capable of providing the proof email service to the recipient device.

The third party institution server may provide a function for checking whether the recipient mail service provider server is a mail service provider server capable of sending / receiving e-mail.

The sender's mail service provider server corresponding to the sender's device may use the recipient's mail service provider identification to determine whether the recipient's device can receive a proof email prior to the request for sending a proof email from the sender's device (or if the recipient's email is You can check in advance whether the e-mail can be received.

If the result of confirming that the e-mail can be received is successful, the next step is to perform the identity verification process for the sender. If the verification fails, provide the sender with information on the inability to send.

A sender mail service provider server that provides a proof email service to the sender device may perform identity verification for the sender (step S520).

In response to the sender request for the sender's attestation e-mail and the confirmation of receipt of the attestation e-mail, the sender's mail service provider server, which provides the attestation e-mail service to the sender's device, requests the identity verification system for the sender. The authentication result can be obtained.

Identity verification uses one or more of non-face-to-face identification methods such as identity verification services (mobile phone number identity verification, credit card number identity verification, etc.), biometric authentication (fingerprints / irises, etc.), i-PIN, and accredited certificates. Can be done.

If the identity verification result is successful, payment can be performed for sending out proof e-mail. If the verification result is unsuccessful, the sender device can provide guidance information about the identity verification failure.

The sender mail service provider server may perform a payment for a proof email sent to the sender (step S530).

If the identity verification result for the sender is successful, the sender's mail service provider server requests the sender to pay for the payment of the proof e-mail so that the payment process is performed between the sender and the payment system, and the payment information is obtained from the payment system. Can be. Bill payment can be performed using a method such as credit card payment, bank account transfer payment, mobile phone micropayment. If the payment result is successful, the next step is to send the proof e-mail. If the payment result is unsuccessful, the sender provides guidance information on the payment failure.

After the sender mail service provider server sends the proof email to the recipient mail service provider server after adding the hash value and converting and encrypting the image, the sender mail service provider server may notify the sender of the completion of the transmission.

When payment is completed, the Token Mail Service Provider server uses the token received from the third party institution server that acts as the e-mail distribution hub to prevent forgery / falsification of content documents (text and attached documents). After adding the generated hash value to the content document body original, encrypting the original attachment document, converting it to an image format, sending it to the recipient mail service provider server, and notifying the sender device of the completion. Can be. Notification of completion of sending e-mail, mobile App. The notification may be by one or more of a push message or a mobile phone text message. At this stage, you can add the phrase '(proof)' before the title of the content document to distinguish the proof email from the normal email. Hash value generation and image conversion may be performed by a third party institution server, or may be used in conjunction with a mail service provider server by installing a client of the mail service provider server. If the mail provider server is built on its own, conformance verification procedures by a third party authority server are required. The cipher system applied for non-repudiation may use symmetric technique (common cryptography) or asymmetric technique (public key cryptography), and the communication protocol for its application may be set by a third party institution server.

The sender's sender mail service provider server may store the completed transmission e-mail in the database and transmit the distribution information to the third party institution server (step S540).

In the case where the storage service of the proof e-mail '(the text and the attached document) is the mail service provider server in charge of the third-party institution server in step S540, the step of storing in the database is not applicable. The sender can check the 'e-mail sent by me' (text and attached document) in his 'provided e-mail box'.
