It also eliminates the inconvenience of users having to remember a password or carry a token. Therefore, it is safer and more convenient than the method of identification using the existing password or password.

Particularly, biometrics using a face shape is convenient because it can be executed without requiring a user to separately touch a specific body part with the recognition device. In addition, it is popular because it is possible to easily implement the face recognition device even if the already-installed PC USB camera or CCD camera is directly used and software is added thereto.

As an example of such a face recognition apparatus, registered patent No. 467152 (name: personal authentication method in a face recognition system) (hereinafter referred to as prior art) can be mentioned. In the above-described conventional technique, the input image is compared with the registered image and the degree of similarity is calculated to determine success or failure of the authentication. Particularly, in the related art, a method for acquiring recognition error factors of weather, illuminance, time, angle, background, illumination, and facial expression from input images and performing authentication with reference thereto is disclosed.

However, in this conventional technique, except for the user's facial expression, the user is only trying to solve the recognition error factors caused by the peripheral elements irrelevant to the user.

Hereinafter, preferred embodiments of a face authentication processing apparatus and a face authentication processing method for providing an optimal guide for face guidance according to the present invention will be described with reference to the accompanying drawings. It is to be understood that the terminology used herein is for the purpose of describing particular embodiments of the invention only and is not intended to be limiting.

First, a configuration of a face authentication processing apparatus that provides an optimal guide for face guidance according to an embodiment of the present invention will be described with reference to FIG. The face authentication processing apparatus of the present invention may include a photographing unit 10, a display unit 20, a storage unit 30, a processing unit 50, and an input unit 40.

The photographing section 10 may include a camera, and can continuously photograph a front side in several frames per second. The photographing unit 10 photographs a face of a user approaching in front of the view angle of the camera to generate a face image. The generated face image can be transmitted to the display unit and / or the processing unit 50. [

The display unit 20 may include an LCD or OLED display means and visually displays the face image generated by the photographing unit 10. [ The display unit 20 can receive the facial image directly from the photographing unit 10 or can receive the facial image from the processing unit 50. [

The storage unit 30 stores one or a plurality of registered face images of one or a plurality of registered users in advance for each registered user. The storage unit 30 may store software related to the functions performed by the processing unit 50. [ Of course, various software and data related to the face authentication processing method and apparatus provided by the present invention can be stored and read out if necessary.

Here, the registered user means a user registered in advance as a legitimate user with respect to the present face authentication processing apparatus. The registered image is a face image of the user registered by the registered user in advance with respect to the face authentication processing device. At this time, the registered image will include the face photographed in the quality, face position and size preferable for the face authentication processing. Further, the face photographed on the registered image may be in a specific posture. The face posture means, for example, that the head is inclined to the left, right, back and back to some extent, or is taking a specific facial expression.

The processing section 50 controls the operation of each part of the face authentication processing apparatus according to the present invention and executes the detailed function of the face authentication processing method. That is, by comparing the arbitrary face image obtained from the photographing section 10 with each of the registered images stored in the storage section 30, it is determined whether or not the user located in front of the current photographing section 10 is the same person as the registered user A face authentication process is performed.

The face authentication process is performed in such a manner that the stored registered image and the obtained face image are compared with each other by a specific face authentication comparison algorithm to calculate the similarity. When the degree of similarity between an arbitrary registered image and the obtained face image is calculated, the calculated similarity degree will be compared with a preset allowance criterion. If the calculated similarity degree exceeds the allowable criterion, the user of the obtained face image The user who tries to authenticate) and the registered user of the registered video are determined to be the same person, and the authentication succeeds.

If the calculated similarity is less than the allowable criterion, the user of the facial image is not a registered user, so authentication failure processing is performed. At this time, the facial image used and the calculated similarity can be stored in the storage unit, and can be utilized for a subsequent authentication log inspection.

On the other hand, if it is determined in the face authentication process that the user who provided the current face image is not the same person as the registered user (authentication failure determination), the processing unit captures the user again to acquire a new face image, The registration image is compared again.

The above comparison procedure is repeated until a predetermined limit number of attempts (for example, 10 times), and if the number of times of the limit attempts is processed as an authentication failure, the current user is finally confirmed as not a registered user , Then the subsequent face authentication procedure may be rejected.

Here, the present invention is characterized in that the optimum guide is displayed on the display unit 20 when the procedure for comparing again reaches a predetermined number (which may be equal to or smaller than the limit trial number). That is, for example, when the number of times is three and the face authentication procedure fails three times, the processing unit displays the optimal guide for guiding the face on the display unit 20, and the user refers to his / When the face image is adjusted, the face image is acquired again, and the face authentication process is re-executed using the acquired face image (position adjusted face image). That is, in the face authentication from the fourth time, the face image whose face position or posture is adjusted through the guide is used.

Here, the optimum guide is set so that the size (or the face position or quality) of the face image photographed at the current photographing section is the same as or larger than the size (or the face position or quality) of the face included in the registered image So that it can be photographed within a certain ratio within a certain ratio.

Further, the optimal guide can guide the user so that the user's face can be photographed in the same manner as the posture of the face included in the registered image. For example, the face of the user can be inclined leftward, rightward and backward by a predetermined angle, or a specific expression can be taken. That is, it is intended to induce the face posture to be adjusted in more detail than the conventional standard face guide which is generally displayed.

The guide of such a function may be displayed in a geometric form configured to include at least one or more of a body part including an eye, eyebrow, nose, mouth, ear, forehead, head contour, facial contour. Hereinafter, as an example, a description will be given of a rectangular shape that is long in the lateral direction so as to include both eyes.

If the face of the registered image is tilted to the left, the guide for both eyes can be displayed tilted to the left, and the user will tilt his head to the left along the guide. Thereby, it becomes possible to acquire a left-leaning face image like a registered image.

Alternatively, in the case where the face of the registered image is winking, the expression of the left and right portions of the guide may be expressed by different shapes.

According to such a configuration, when the user approaches the photographing unit and attempts to authenticate the face, the face of the user is photographed differently from the registered image already registered, so that the situation in which the face authentication repeatedly fails can be quickly resolved. That is, if the user repeatedly fails to perform face authentication, the user can adjust the face position with reference to the displayed guide, thereby making it possible to photograph his / her face similar to the face included in the registered image. As a result, it is possible to reduce the face rejection rate of the user whose authentication is determined to be failed even though the registered user tries to authenticate the face.

On the other hand, the face authentication processing apparatus according to the present invention may maintain a plurality of registered images for one registered user, or may maintain one or a plurality of registered images for each of a plurality of registered users. This means that when a user attempts to authenticate a face, a plurality of registered images should be compared with respect to one face image, respectively. Therefore, it is necessary to consider which registered image is used to provide an optimal guide.

When a certain face image is acquired and a face authentication process for calculating the similarity of each of all or a part of a plurality of registered images is performed and authentication success or failure is determined, Lt; / RTI > When the authentication process is repeated a plurality of times and a guide is to be displayed, the processing unit 50 may select a registered image showing the highest similarity among the similarities calculated each time the face image fails authentication.

Then, the processing unit 50 can generate and display the optimum guide using the selected registered image (that is, the one with the highest similarity among the registered images subjected to authentication failure processing).

On the other hand, the face authentication processing after the optimal guide is displayed will be performed using the newly acquired face image (face image obtained by adjusting the face position by the optimum guide) and the selected registered image. Alternatively, it may be repeated using the newly obtained face image and all of the stored registered images.

Alternatively, it may be considered to provide an optimal guide for face authentication using a registered image that has been most recently registered, or a registered image having the largest number of authentication success (or failure) times.

On the other hand, when the registered image is photographed, the display unit can provide a face guide for guiding the user's face in a form similar to the optimal guide. For example, a face guide having a shape of a rectangle long in the horizontal direction, in which both eyes are to be positioned, is sequentially displayed on the upper part of the display part, the lower part thereof, and the center part, Acquire an image, and store each of the obtained face images as a plurality of registered images. Each registered image can be set so as to know at which position the face guide is photographed.

Then, when a registered image having the highest degree of similarity is identified after the authentication attempting user has made a predetermined number of authentication failures, the face guide used when the registered image is captured is identified, and the same shape and position So that the optimum guide of the display unit can be displayed on the display unit.

The face authentication processing apparatus according to the present invention further includes an input unit for inputting predetermined identification information from a user before or during an attempt of face authentication and a method for comparing a registered image related to the input identification information with the obtained face image The face authentication process may be performed.

For this purpose, when registering a registered image, a procedure for associating predetermined identification information should be performed.

The identification information may be composed of a digital / analog signal, which means one or more letters or numbers.

The input unit 40 is configured to receive the identification information through at least one of RFID, NFC, Bluetooth, infrared communication, magnetic card, and button operation.

When the user first inputs the identification information to the input unit 40 in order to attempt the face authentication, the processing unit 50 fetches the registered image related to the identification information inputted from the storage unit 30, And the authentication process is performed by comparing the obtained facial images.

Alternatively, after the face authentication process is performed using only the user's face image, the user may be requested to input identification information for additional user verification.

Alternatively, identification information may be input after it is determined that authentication has failed a predetermined number of times, and face authentication may be correctly performed using only the registered image associated with the identification information. In this case, adjustment such as lowering the tolerance standard of the degree of similarity in which authentication is determined to be successful may be applied.

According to the face authentication processing apparatus provided with the optimal guide for guiding a face according to an embodiment of the present invention having the above-described configuration, when it is determined that authentication is repeated a plurality of times even though the registered user is a registered user, It provides an optimal guide for guiding a user's face so that it can be photographed in a position / posture such as a face, acquires an optimal face image by photographing a face adjusted in accordance with an optimal guide, The degree of similarity with the registered image is calculated, so that the probability that the face authentication is determined to be successful is increased.

Thereby, it is possible to reduce the error (self-authentication rejection rate) of the registered user's face authentication attempt, and to solve the inconvenient situation in which the face authentication is repeatedly failed.

2 is a view showing a general guide for a face guide and an optimal guide for guiding a face according to an embodiment of the present invention in comparison. In a general face authentication apparatus, a face guide in the form of surrounding the entire face of the user is displayed on the display unit 20, as shown in Fig. 2 (a). Such a guide provides an advantage that the user can quickly position and adjust his / her face within the viewing angle of the photographing unit 10. However, the distance between the face and the photographing unit 10, the quality of the image to be photographed, There is a disadvantage in that it is not possible to provide information on the information. This disadvantage may cause a problem of increasing the face rejection rate of the user and / or the acceptance rate of the other face.

On the other hand, FIG. 2 (b) shows an example of an optimal guide for guiding a face, which is provided in an embodiment of the present invention. In the present invention, by displaying the optimum guide for adjusting the eye position on the display unit, the manner in which the face is photographed can be induced. This will be described later with reference to FIG.

Fig. 3 shows various examples of an optimal guide for guiding a face that can be displayed on the display unit. The figure shows an example using guides for both eyes. Optimal guides include a "T" shaped guide that includes both eyes and nose as well as a "I" or "ㅗ" shaped guide that includes nose and mouth, as well as both eyes, "∇ "Or" = "guides.

3 (a) to 3 (c), the size of the photographed face image may vary depending on the position of the optimal guide on the upper portion, the slightly lower portion, and the middle portion of the display portion 20 Can be seen. In this way, it is possible to induce the distance between the user's face and the photographing unit (or the resolution, quality, etc. of the photographed face) to be different.

In addition, as shown in Fig. 3 (d), by tilting and displaying the guide, the user will be able to acquire a face image including a tilted face posture.

In addition, by varying the size of the guide, the face may be photographed larger or smaller. Further, by configuring the left and right shapes of the guide symmetrically or asymmetrically, it is possible to induce various face postures. For example, if the guide to the left eye is displayed at a normal size and the guide to the right eye is displayed at a smaller size, the user will make a facial expression by winking the right eye (not shown).

4 and 5, a face authentication processing method for providing an optimal guide for face guidance according to another embodiment of the present invention will be described. 4 is a flowchart briefly explaining a face authentication processing method for providing an optimal guide for face guidance according to an embodiment of the present invention.

First, a registered user makes his / her face to be photographed in accordance with various face guides, and a plurality of registered images are stored (S11).

Then, the user who wants to try the face authentication brings his face close to the photographing section 10 of the face authentication processing device. The device recognizes that the user has approached it, and creates a face image by photographing the user's face through the photographing unit 10 (S12).

The processing unit 50 compares the generated face image with an arbitrary registered image stored in the storage unit 30 to perform a face authentication procedure (S13). The similarity is calculated for the face authentication procedure (S14). If the calculated degree of similarity exceeds the preset allowance, it is determined that the authentication is successful. Otherwise, if the degree of similarity is below the allowance, it is determined that the authentication fails (S15). If it is determined that the authentication is successful, the process proceeds to step S22, and if it is determined that the authentication fails, the process proceeds to step S16.

If authentication failure is determined in step S15, it is checked how many times the current number of failures is present (S16). If the number of failures is less than a predetermined reference number, the user's facial image is acquired again, and the authentication procedure is repeatedly executed using the new facial image. Then, if the number of failures exceeds the reference number, the registered image showing the maximum similarity among the similarities calculated at the time of the authentication failure determination is checked (S17), and the optimum guide generated by referring to the registered image with the maximum similarity is displayed on the display (S18).

If the face image is acquired while the user's face is adjusted in accordance with the guide (S19), the authentication process is performed using the obtained face image and registered image (S20). The registered image used at this time may be the registered image of the maximum similarity.

If it is determined in step S21 that the face authentication process is successful, the process proceeds to step S22. If it is determined that the authentication is failed, the process returns to step S17, and the face image is again photographed while the guide is displayed, and the authentication procedure is repeated.

5 is a flowchart illustrating a face authentication processing method for providing an optimal guide for face guidance according to another embodiment of the present invention. In the embodiment of FIG. 5, the case where each registered image is associated with arbitrary identification information. This embodiment adds a method of selectively using a registered image according to the identification information in the face authentication processing method of Fig.

First, a user attempting authentication attempts to input identification information to an authentication processing device in such a manner that a password is input using a keypad or a password is transmitted using a magnetic card or non-contact communication means before his or her face is photographed (S31).

In the authentication processing apparatus, one or a plurality of registered images associated with the obtained identification information are read out from the storage unit and prepared (S32).

Then, the face image of the user is captured through the photographing unit 10 to acquire the face image (S33), and the obtained face image and the prepared registered image are compared with each other to perform the face authentication procedure (S34).

In a case where a plurality of users are registered as a registered user in the storage unit 30, when facial authentication is attempted and both the photographed face image and a plurality of registered images are compared, the processing time becomes long and the processing load . On the other hand, when the registered image based on the identification information and the acquired face image are compared with each other as in the above-described method, the number of comparison objects is small, so that quick face authentication processing becomes possible.

On the other hand, input of such identification information can be made when the face authentication is attempted for the first time. In addition, if the face authentication is first performed and the face authentication fails a predetermined number of times, the user may be requested to input identification information.

The embodiments of the present invention described above are merely illustrative of the technical idea of the present invention, and the scope of protection of the present invention should be interpreted according to the claims. It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the essential characteristics thereof, It is to be understood that the invention is not limited thereto.
