DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

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

1 is a configuration diagram showing the configuration of an electronic notary authentication system using an image authentication technique according to a preferred embodiment of the present invention. Referring to FIG. 1, an electronic notarization system using an image authentication technology includes an entrusted terminal 100 and a designated notarized terminal 200.

The entrusted terminal 100 confirms the identity of the entrusted person and receives the completed notarized document through digital signature with the designated notary. The input terminal 110, the control unit 120, the communication unit 130, and the display unit 140, .

The input unit 110 includes input means such as a camera, a keyboard, a mouse, a microphone, and the like. The input unit 110 receives input data such as an answering oath or an electronic signature on a requestor and transmits the input data to the controller 120. The control unit 120 transmits the input data received from the input unit 110 to the communication unit 130 and transmits the input data to the designated notary terminal 200. The control unit 120 transmits the data received from the communication unit 130 to the display unit 140 do.

The communication unit 130 receives the data for confirming the real time of the requesting party and the input data of the requesting party from the control unit 120 and transmits the data to the designated notary party's terminal 200, And sends the data for confirming the identity and the notarized document to the control unit 120. Finally, the display unit 140 displays the data for confirming the authenticity of the entrusted person and the identity of the entrusted person, the completed notarized document received from the control unit 120, and provides the displayed information to the entrusted person.

Next, the designated notary's terminal 200 receives the real-time performance and identity confirmation of the entrusted person, determines whether or not to confirm the addition of the identity, encrypts and stores the entrusted person's read aloud of the affirmative and stores the completed notarized document And a control unit 220, a communication unit 230, and a display unit 240. The input unit 210 includes a control unit 220, a communication unit 230, and a display unit 240.

The input unit 210 includes input means such as a camera, a keyboard, a mouse, and a microphone in the same manner as the input unit 210 of the terminal 100 that is an entrusted terminal. The input unit 210 inputs an identification of the additional identification of the designated notary, And transmits the data to the control unit 220. The control unit 220 transmits the input data received from the input unit 210 to the communication unit 230 and transmits the input data to the terminal 100 that is in charge of the contract and transmits the data received from the communication unit 230 to the display unit 240 do. Also, the control unit 220 can encrypt and store the affirmative read aloud of the entrusted person received from the communication unit 230.

The communication unit 230 receives the input data of the designated notary public from the control unit 220 and transmits the input data to the terminal 100 which is a caller and receives the real-time property and identity confirmation data and the acknowledgment read- To the control unit 220. Finally, the display unit 240 displays the real-time nature of the entrusted person, the identification data received from the control unit 220, the acknowledgment read-aloud data, and the like, and provides it to the designated notary.

The electronic notary system using image authentication technology has been described above. Next, I will explain the preparatory steps for using the electronic notary system. In order to use the electronic notarization system, you must prepare an official certificate in advance and access the electronic notarization system web page (http://enotary.moj.go.kr/) to register and log in. When registering, the contractor enters his or her cell phone number, and in this process, performs a procedure of confirming whether the cell phone is his / her own name through SMS authentication.

Next, the entrustor logs in from the homepage (login of the authorized certificate) and applies for authentication of the electronic document and the electronic document in the entrusted menu. The electronic document is a scanned general form and it is prepared before the application for an entrustment. Then select the type of notary (librarian / constitution / minutes) and designated notary, and attach a notarial document. If you press the Apply button, PDF file conversion / merging of the electronic document is performed. In this process, the digital signature of the PDF conversion server is added. The solicitor completes the electronic notarization application by electronically signing the converted PDF file with the official certificate.

Next, the designated notary examines the details of the application and sends an image-face authentication schedule to the trustee via e-mail. If it is deemed necessary for additional identification process, e-mails will be sent to the portal site of the Korean government's civil affairs portal together with the authentication certificate, and the ID of the applicant will be sent to the applicant for issuance of the resident registration third party To be completed. In case of face-to-face authentication, the acknowledgment letter of the trustee is recorded / recorded, and the trustee is notified of the fact in accordance with the Communication Confidentiality Protection Act.

As described above, the preliminary preparation step has been described and the electronic notarization method using the image authentication technique will now be described with reference to FIG.

2 is a flowchart showing an electronic notarization method citing an image authentication technique according to a preferred embodiment of the present invention.

Referring to FIG. 2, the designated notary verifies the real-time nature of the trustee (S10). The real-time verification is to prevent the malicious user from performing the notarization procedure by impersonating the trustee by transmitting the previously recorded images in the process of confirming the identity. In order to prevent such replay attack, a challenge-response method is applied.

In real-time verification, it is possible to prove to the trustee each time a new random number is selected and input or read the letter so that the screen of the designated notary is communicated in real time rather than the recorded screen. In some cases, a random phrase or a CAPTCHA (Completely Automated Public Test) may be used, and will be described in detail with reference to FIGS. 3 and 4, respectively.

FIG. 3 is a diagram showing real-time verification by confirming a random phrase. FIG. Referring to FIG. 3, when the designated notary public places a random phrase on the screen and the corresponding phrase is input or responded correctly within a predetermined time, the certification pass is passed. Otherwise, the certification failure can be confirmed. At this time, the random phrase may generate new numbers and characters using the time information in which the face-to-face authentication is performed or by using a pseudo random function (PRF).

Next, FIG. 4 is a diagram showing real-time verification by checking a CAPTCHA image. The CAPTCHA image means a technique for displaying a modified image so that only a person can recognize it, and the real time property can be verified when the authentication is performed. As shown in FIG. 4, when the designated notarial person displays the CAPTCHA phrase on the screen and inputs or replies the phrase correctly within the predetermined time, the authentication is passed. Otherwise, the authentication failure can be confirmed.

As described above, two methods of verifying the real-time property have been described. Next, I will return to Figure 2 and explain the next step. The designated notary confirms identity when the authenticity of the trustee is completed (S20). More specifically, the identity verification will be described with reference to FIG.

FIG. 5 is a view showing identity verification by confirming an identification card. FIG. Referring to FIG. 5, the trustee displays an identification card on the screen for identification. An identification card is issued by a country, such as a national ID card, driver's license or passport, and must include photographs. At this time, if the screen showing ID is transmitted on the communication, the personal information is exposed and the communication is encrypted using TLS protocol and SRTP protocol. The designated notary public can confirm the identity of the entrusted person by checking the encrypted ID.

Next, returning back to FIG. 2, a description will be given after the identity verification step (S20). If the designated notary public doubts about the identity of the trustee after the identity verification step (S20), it may decide whether to confirm the addition of the identity (S30). If the designated notary public determines that additional identification is necessary, the additional identification is confirmed (S40). Here, the identity addition confirmation step (S40) can be carried out using an online issuance of a resident registration third party or a mobile phone authentication of a person entrusted with residence registration.

More specifically, the confirmation of the identification using the resident registration third party online issuance must first be approved by the designated notary public in the portal site of the Korean government's civil affairs portal, and the ID of the site should be notified of the date of the face-to- You must inform the entrant.

Next, the entrusted person visits the portal site of the Government of the Republic of Korea and applies for the online issuance of resident registration. In the application process, the method of receipt is selected as 'third party receipt', and the third party is searched with the ID of the designated notary public so that the designated notary can apply for the online third party issuance so that the resident registration copy of the entrusted person can be received online do. All of these steps must be completed before performing the face-to-face authentication.

Finally, the designated notary can check the identity of the designated person by checking the identity of the designated person's identity on the screen of the trustee after receiving the resident registration certificate of the trustee by accessing the site during the image-face authentication process .

Next, the identification of the additional person using the mobile phone authentication of the authorized person should be done first by the entrant entering his / her cell phone number when signing up for the entrusted application or the electronic notarization system web page. At this time, in order to prevent a case where an incorrect number is input, a mobile phone authentication process is required to confirm whether the authentication number transmitted to the input mobile phone number is correctly input.

After the authentication is completed, when the designated notary person wishes to perform the cell phone authentication, the caller calls the entered cell phone number in the image-facing state and performs communication with the trustee. The trustee can be authenticated by confirming that the information transmitted on the telephone is accurately spoken on the screen.

After the confirmation of addition of identity is completed as described above, the designated notary public and the trustee confirm the notarized document (S50). More specifically, the designated notary public displays the requested electronic document, and the entrustor verifies that the electronic document desired to be processed by the designated notary is the document to which he / she subscribes, and then proceeds to the next step if there is no change , And if a problem occurs, the image-face authentication can be terminated.

Next, after the notarized person's confirmation of the notarized document is completed, the outgoing person reads the text of the designated notary, that is, the affidavit (S60). Through the reading of the affidavit, the entrusted person acknowledges the application for entrustment. The statement shall include the date and time information on the face-to-face authentication and information about the notarized document, and the designated notary can record or record it, encrypt it, and store it for possible future problems.

After the written affidavit, the designated notary will create the authentication part in electronic form in the electronic notary system, and upload the signature to the system. The system signature is added to the notarized document including the electronic signature of the appointed person and the designated notarial person to complete the notarized document (S70).

When the notarized document is completed, the entrant makes an electronic settlement to pay the fee. Depending on the entrant's choice, the fee can be paid to the designated notary in real time via mobile phone payment, credit card payment, or account transfer. When payment of the fee is confirmed, the designated notarized person completes the notarization procedure and transmits the electronic notarized document file to the contractor (S80). The communication at the time of transmission is performed in an encrypted manner, and the final file received from the designated notary person by the entrustor can be opened by a program provided by the electronic notary system, and the generation time and validity of the digital signature can be confirmed.

The entrustor can confirm that the notarized document received from the designated notary is normally processed through the program, and if there is no problem, the e-notarization can be performed by using the image authentication technique by terminating the image face-to face with the consent of the two persons .
