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

1. Authorized biometric authentication system

1 is a view showing a certified biometric authentication system according to an embodiment of the present invention. The authorized biometric authentication system according to the embodiment of the present invention is a system for registering authorized biometric information and providing a personal authentication (identity verification) service using registered registered biometric information.

1, the authorized biometric authentication system according to an embodiment of the present invention includes a mobile terminal 100, a certified biometric authentication server 300, an ID verification server 20, and a SP (Service Provider) server 30).

The mobile terminal 100 is required to have the authorized biometric authentication application 200 installed therein. The authorized biometric authentication application 200 is an application for registering the biometric information of the user 10 in the authorized biometric authentication server 300 and performing the authorized biometric authentication of the user 10 using the registered biometric information.

In the biometric information registration process, the authorized biometric authentication application 200 checks authenticity of the ID of the user 10 in cooperation with the authenticity verification server 20. The authenticity verification server 20 can be realized by a server operated by a public office, which is an authorized institution that can confirm the authenticity of the identification card.

The SP server 30 is a service operated by an institution that provides services requiring authorized biometric authentication. In order for the user 10 to use the service provided by the SP server 30, a corresponding service application (not shown) must be installed in the mobile terminal 100, and the service application must be installed in the authorized biometric authentication application 200 The authorized biometric authentication shall be requested.

When the authorized biometric authentication application 200 acquires the biometric information necessary for the authorized biometric authentication and transmits it to the authorized biometric authentication server 300, the authorized biometric authentication server 300 compares the transmitted biometric information with the registered biometric information, And performs biometric authentication.

2. How to register certified biometric information

Hereinafter, the process of registering the authorized biometric information of the user 10 by the authorized biometric authentication system shown in FIG. 1 will be described in detail with reference to FIG. 2 to FIG. FIGS. 2 to 4 are views for explaining a registered biometric information registration method according to another embodiment of the present invention.

As shown in FIG. 2, the user 10 first instructs the authorized biometric authentication application 200 to apply for registered biometric information registration (S405), and the authorized biometric information registration procedure is started.

The authorized biometric information registration application can be executed not only by the user 10 directly executing and issuing the authorized biometric authentication application 200 but also by the other service applications (SP server 30 and the like) associated with the authorized biometric authentication application 200 And indirectly execute and instruct the authorized biometric authentication application 200 through an application that provides services in cooperation with each other.

Upon receiving the command, the authorized biometric authentication application 200 activates the camera function of the mobile terminal 100 and requests the user 10 to take an ID card (S410). Step S410 is performed in such a manner as to display a guidance message requesting to "photograph the ID card" on the screen of the mobile terminal 100. [

When the photographing of the ID card is completed (S415), the authorized biometric authentication application 200 transmits the photographed ID card image to the ID card authenticating server 20 (S420).

The authenticity verification server 20 confirms the authenticity of the identification card (S425), and returns the confirmation result to the authorized biometric authentication application 200 (S430).

If it is determined in step S425 that the genuine identity card is not falsified, the authorized biometric authentication application 200 performs user authentication for the mobile terminal 100 (S435).

The user occupancy authentication in step S435 is a procedure for confirming whether the user 10 occupying the mobile terminal 100 is the name of the mobile terminal 100, using the personal authentication service provided by the mobile communication company .

When the user 10 is identified by the name of the mobile terminal 100, the authorized biometric authentication application 200 requests the authorized biometric authentication server 300 for a random number (S440). The certified biometric authentication server 300 that has received the random number generates a random number (S445), and transmits the generated random number to the authorized biometric authentication application 200 (S450).

Then, the biometric authentication application 200 displays the random number received in step S450 on the screen (S455), activates the camera function of the mobile terminal 100, and then requests the user 10 to take a face image and talk (S460 ).

The utterance request in step S460 includes a utterance request of the digit sequence (0 to 9) and a utterance request of the random number indicated in step S455. The user interface screen created by the authorized biometric authentication application 200 on the screen of the mobile terminal 100 for the face photographing and the utterance request in step S460 is illustrated in FIG.

In the screen of Fig. 3, "0 1 2 3 4 5 6 7 8 9" is a phrase for requesting utterance of a digit string, and "6 3 2 4 1" is a phrase for requesting utterance of a random number.

Accordingly, the user 10 speaks the number sequence (0 to 9) and the random number 63241 on the screen while watching the camera of the mobile terminal 100 (S465), and the authorized biometric authentication application 200 transmits the number 10) (S470).

Then, as shown in FIG. 4, the authorized biometric authentication application 200 requests registration of the authorized biometric information while transmitting the ID photo and the moving image to the authorized biometric authentication server 300 (S505).

The ID photo transmitted to the authorized biometric authentication server 300 is photographed in step S415 of FIG. 2, and the moving image is photographed in step S470 of FIG.

The authorized biometric authentication server 300, which is requested to register the authorized biometric information, recognizes the random number generated by the user 10 in the received moving image (S510), and recognizes the recognized random number as the random number generated in step S445 (S515).

The confirmation in step S515 is a configuration for excluding 'random authentication attempt'. 'Random authentication attempts' refers to cases where random attempts are made using malicious codes or hacking programs.

When the random numbers match, the authorized biometric authentication server 300 acquires the mouth shapes of the user 10 at the time of generating a random number in the received moving picture, and the acquired mouth shapes match the mouth shapes for the random number utterance recognized at step S510 (S520).

Step S520 corresponds to a configuration for excluding an " illegal authentication attempt using a photo / moving image ". The 'illegal authentication attempt using a photo / video' refers to an unauthorized authentication attempt by a user other than the user 10 with a picture or a moving picture of the user 10 on the camera.

If the mouth shape matches, the authorized biometric authentication server 300 extracts the facial features from the received ID image (S525), and extracts the facial features of the face of the user 10 appearing in the received moving image (S530).

Then, the authorized biometric authentication server 300 compares the facial feature extracted in step S525 with the facial feature extracted in step S530, and performs authentication of the user (step S535). Accordingly, the user 10 does not need to check the identification card while facing the corresponding employee of the financial institution directly or indirectly through the video call.

In step S535, the authorized biometric authentication server 300 extracts the voice characteristics of the user 10 in units of numbers from the digitally generated portion of the user 10 in the moving image (S540).

That is, the speech characteristic in uttering '0', the speech characteristic in speech uttering '1', and the speech characteristic in uttering '9' are extracted in step S540.

Next, the authorized biometric authentication server 300 stores the facial feature extracted in step S530 and the voice feature extracted in step S540 in the DB and registers it in step S545.

Then, the authorized biometric authentication server 300 notifies the authorized biometric authentication application 200 that the authorized biometric information registration is completed (S550), and the authorized biometric authentication application 200 notifies the user 10 of the completion of the registration S555).

3. Authorized biometric authentication method

Hereinafter, the process of performing the authorized biometric authentication for the user 10 by the authorized biometric authentication system shown in FIG. 1 will be described in detail with reference to FIG. FIG. 5 is a flowchart provided in the explanation of the authorized biometric authentication method according to another embodiment of the present invention.

As shown in FIG. 5, when the authorized biometric authentication application 200 receives the authorized biometric authentication request (S605), the authorized biometric authentication procedure is started.

The authorized biometric authentication request is received from another service application associated with the authorized biometric authentication application 200 (such as an application providing a service in conjunction with the SP server 30).

Upon receiving the authorized biometric authentication request, the authorized biometric authentication application 200 requests the authorized biometric authentication server 300 for a random number (S610). The authorized biometric authentication server 300 that has received the random number generates a random number (S615), and transmits the generated random number to the authorized biometric authentication application 200 (S620).

Then, the authorized biometric authentication application 200 displays the random number received in step S620 on the screen (S625), activates the camera function of the mobile terminal 100, and then requests the user 10 to take a face image and talk S630).

In step S630, it is requested to speak about the random number displayed in step S625. The user interface screen generated by the authorized biometric authentication application 200 on the screen of the mobile terminal 100 for the face photographing and the utterance request in the step S630 is "0 1 2 3 4 5 6 7 Quot; 8 "< / RTI >

The user 10 speaks the random number displayed on the screen while watching the camera of the mobile terminal 100 in step S635 and the authorized biometric authentication application 200 captures the user 10 in step S640.

Then, the authorized biometric authentication application 200 requests the authorized biometric authentication while transmitting the moving image to the authorized biometric authentication server 300 (S645). The moving image transmitted to the authorized biometric authentication server 300 is photographed in step S640.

The authorized biometric authentication server 300 which has received the authorized biometric authentication voice recognizes the random number generated by the user 10 in the received moving image (S650), and checks whether the recognized random number matches the random number generated in the step S615 (S655). The confirmation in step S655 is a configuration to exclude a random authentication attempt.

When the random numbers match, the authorized biometric authentication server 300 acquires the mouth shapes of the user 10 when a random number is uttered in the received moving picture, and the acquired mouth shapes match the mouth shapes for the random number utterance recognized in operation S650 (S660). Step S660 corresponds to a configuration for excluding an unauthorized authentication attempt using a photograph / moving picture.

When the mouth shape matches, the authorized biometric authentication server 300 extracts the voice characteristics of the user 10 from the moving picture in the unit of numbers constituting the random number (S665).

For example, in the case where the random number is "63241", the speech characteristic in speech uttering "6", the speech characteristic in uttering "3", the speech characteristic in uttering "2" And the speech characteristic in speech of '1' are extracted in step S665.

In step S670, the authorized biometric authentication server 300 compares the voice features extracted in step S665 with the voice features of the user 10 stored in the DB, and confirms the matching. Corresponds to the voice authentication of the authorized biometric information authentication of the user 10.

Then, the authorized biometric authentication server 300 extracts the facial features of the user 10 from the received moving image (S675). In step S680, the authorized biometric authentication server 300 compares the facial features extracted in operation S675 with the facial features of the user 10 stored in the database. This corresponds to facial authentication during authenticating biometric information authentication of the user 10.

Next, the authorized biometric authentication server 300 notifies the authorized biometric authentication application 200 of the authorized biometric authentication result (S685), and the authorized biometric authentication application 200 delivers the notified official biometric authentication result to the requested application S690).

The communication unit 110 is a means for communicating with the authorized biometric authentication server 300, the identification authenticity verification server 20, and the SP server 30. The touch screen 120 functions as a display means for displaying an execution result by the processor 130 and an input means for receiving a user command and transmitting it to the processor 130.

The processor 130 executes the authorized biometric authentication application 200 to execute the processes of 'registration necessary for biometric information registration shown in FIG. 2 and FIG. 4' and 'procedure for authorized biometric authentication shown in FIG. 5' And processes the procedures performed by the authorized biometric authentication application (200).

The camera 140 is used to capture the identification and facial & vocal appearance of the user 10.

The processor 320 performs the authentication process by the authorized biometric authentication server 300 among the procedures necessary for the registration of the authorized biometric information shown in FIGS. 2 and 4 and the procedures for the authorized biometric authentication shown in FIG. Processes.

The DB 330 stores the facial features and the voice features of the user 10 as biometric information.

6. Variation example

Hereinafter, preferred embodiments have been described in detail for a method and system for registering authorized biometric information using online identification, facial authentication, and voice authentication, and performing authorized biometric authentication using the same.

In the registration process presented in the above embodiment, it is assumed that both face authentication and voice authentication are applied. However, this can be implemented differently by way of example. In other words, voice authentication can be omitted, and only facial authentication can be implemented.

In this case, the authorized biometric authentication application 200 does not need to transmit the user's moving image to the authorized biometric authentication server 300, and it suffices to take a still image (photograph) and transmit it.

It is also assumed that both the facial authentication and the voice authentication are applied in the authentication process shown in the above embodiment. However, since this is also an example, it is needless to say that it is possible to implement the authentication procedure with either one of them.

Further, in the above-described embodiment, the voice authentication is implemented by a procedure including two types of confirmation of a random number and a mouth type confirmation, but it is also possible to omit one of them.

In the above embodiment, it is assumed that the registration process and the authentication process are performed by the authorized biometric authentication server 300, but the modification is performed so as to be performed in the authorized biometric authentication application 200. [ In this case, off-line authorized biometric authentication becomes possible.

In addition, it is possible to implement that the SP server 30 performs the role of the ID verification server 20 in FIG. At this time, the SP server 30 can perform the authenticity verification of the ID card directly or can ask the office server.

On the other hand, in both the authorized biometric information registration process and the authorized biometric authentication process, authentication by comparison of facial characteristics is performed. The former compares the facial feature extracted from the ID image and the facial feature extracted from the captured video, and the latter compares the registered facial feature and the facial feature extracted from the captured video, respectively. At this time, the agreement degree of the facial feature required for the authentication success in the former can be set lower than the matching degree of the facial feature required for the authentication success in the latter. It is considered that facial feature extraction may be inaccurate because the resolution or sharpness of the ID image is not sufficient.

It goes without saying that the technical idea of the present invention can also be applied to a computer-readable recording medium having a computer program for performing the functions of the apparatus and method according to the present embodiment. In addition, the technical idea according to various embodiments of the present invention may be embodied in computer-readable code form recorded on a computer-readable recording medium. The computer-readable recording medium is any data storage device that can be read by a computer and can store data. For example, the computer-readable recording medium may be a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, an optical disk, a hard disk drive, or the like. In addition, the computer readable code or program stored in the computer readable recording medium may be transmitted through a network connected between the computers.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the present invention.
