TECHNICAL FIELD [0001] The present invention relates to a multi-

The present invention relates to authentication using biometric information, and more particularly, to a method and apparatus for remote multi-biometric authentication.

As the information society becomes more mature, the need for security and authentication technology becomes more and more important. Various approaches to user recognition have been developed. Among them, the recognition method using biometric information recognizing the physical characteristics such as face shape, iris, fingerprint, voice, etc., has a high reliability, ease of use, and fast authentication speed, thereby increasing its share.

Recently, since only one piece of biometric information is used, many methods for recognizing a plurality of pieces of biometric information are disclosed in order to improve reliability or increase recognition efficiency. Since face recognition is fast but reliability is low and fingerprint authentication is inefficient in fetching a database, a multi-biometrics measurement system based on face, fingerprint and voice has been developed in order to secure this shortcoming, .

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

In order to clearly illustrate the present invention, parts not related to the description are omitted, and similar parts are denoted by like reference characters throughout the specification.

Throughout the specification and claims, when a section is referred to as " including " an element, it is understood that it does not exclude other elements, but may include other elements, unless specifically stated otherwise.

Hereinafter, a method and apparatus for remote multi-biometrics recognition according to an embodiment of the present invention will be described.

In the embodiment of the present invention, a plurality of pieces of biometric information about an object to be authenticated are acquired using one image processing apparatus, and authentication is performed using a flexible structure that can be applied as needed.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a diagram illustrating a concept of remote multi-biometric recognition according to an embodiment of the present invention.

As shown in FIG. 1, in the embodiment of the present invention, biometric information acquisition and authentication are performed for each set interval of a to-be-recognized person walking at a long distance. In order to acquire and authenticate biometric information, a plurality of sections are set for the recognizable area and used. Specifically, the first setting interval, the second setting interval, and the third setting interval are set, and the distance from the multi-biometric device according to the embodiment of the present invention to each section of the first to third setting intervals is The first setting section> the second setting section> the third setting section. That is, the first setting interval corresponds to the farthest interval from the multi-biometric device, and the third setting interval corresponds to the closest interval from the multi-biometric device.

The first setting period is a target tracking period in which the multi-biometric device according to the embodiment of the present invention tracks a target to be recognized. The multi-biometric identification device tracks the face, eye, and hand position of the to-be-recognized person when the to-be-recognized person appears in the first setting section. In this case, image tracking is performed while processing such as eye coordinate based face tracking, eye height (key) recognition, hand tracking / finger recognition, and the like.

In order to track the position of the face, eyes, and hands of the person to be recognized, an infrared camera is used in the embodiment of the present invention, but the present invention is not limited thereto. In addition, the face, eye, and hand are used as the biometric information, but the face, eye, and hand are used as tracking objects. However, the present invention is not limited thereto. , It is possible to additionally track the target of tracking for acquiring the corresponding biometric information.

When the recognition subject enters the first setting period (for example, when approaching a point corresponding to 3 m from the multi-biometric device), the infrared camera operates with the infrared illumination and the infrared ray filter to cut off the external visible light, The image of the face, eye, and hand of the perceived subject is imaged. Further, it is also possible to adaptively change the shooting angle (e.g., tilt angle of the camera) and the shooting speed (e.g., shutter speed) of the infrared camera while adjusting the moving direction and the speed of the to- And performs image tracking on the tracked object. In addition, the photographing angle of the camera can be adjusted according to the eye height of the to-be-recognized person.

The second setting section is a biometric section for acquiring biometric information on at least one tracking target after tracking of a plurality of tracking targets for the to-be-recognized object. The second setting period may be set according to the focal distance of the camera (infrared camera or the like) to be used. For example, the photographable focal distance of the infrared camera can be set as the start position of the second setting section at which the acquisition of the biometric information starts.

When the subject to be authenticated enters the focal distance, that is, the second setting section (for example, when approaching a point corresponding to 1.5 m from the multi-biometric device), one tracking target is selected from the tracking targets. Specifically, a plurality of images for the tracking objects are acquired according to the image tracking in the first setting period, and the biometric information is acquired based on the plurality of acquired images. In this case, it is possible to select the image of the tracking object having the highest quality among the acquired images, and obtain biometric information on the tracking object corresponding to the selected image. For example, in the first setting period, a plurality of images are acquired by continuously photographing the face, the eyes, and the hands in accordance with the image tracking, the image having the highest resolution is selected from among the acquired images, If the image corresponds to a face, an eye, or a hand, biometric information (face image or iris information of the eye or fingerprint of the hand) corresponding to the face, the eye, or the hand is acquired.

The third setting period is a recognition algorithm processing period for performing authentication using biometric information obtained in the second setting period. When one tracking object (face or iris or fingerprint) is selected for a plurality of tracking objects in the second setting period and biometric information (face image, eye iris information, or hand fingerprint) of the selected tracking object is acquired, And performs authentication processing based on comparison with pre-stored registration information according to a recognition algorithm corresponding to the biometric information. For example, when the face image is acquired, the authentication process is performed through comparison between the face image obtained according to the face recognition algorithm and the pre-stored face registration information, and when the iris image of the eye is acquired, The authentication process is performed by comparing the iris image and the previously stored iris registration information. When the fingerprint image is acquired, the authentication process is performed by comparing the fingerprint image acquired according to the fingerprint recognition algorithm with the stored fingerprint registration information do. Here, in the authentication process based on the fingerprint image, a non-contact fingerprint authentication system can be separately configured to improve the reliability.

FIG. 2 is a view illustrating an example of a process of acquiring biometric information according to image tracking for a to-be-recognized person according to an exemplary embodiment of the present invention. 3 is an exemplary view illustrating an image obtained according to an image tracking for a to-be-recognized person according to an embodiment of the present invention.

As shown in (a) of FIG. 2, a plurality of images are acquired by performing face tracking and eye tracking of a to-be-recognized person using an infrared camera, as shown in FIG. 2 (a). The face identification and extraction are performed on the acquired images to acquire a face image as illustrated in FIG. 3 (a), and iris identification and extraction are performed on the obtained plurality of images, The iris image as illustrated in FIG. 2 (b), a plurality of images are obtained by performing hand tracking of a to-be-recognized person, and finger identification and extraction are performed on the obtained plurality of images, Obtain a fingerprint image such as a bar.

The acquisition of the face image, the iris image, and the finger image as described above may be all performed, and in some cases, only a part of the images may be acquired. When the face image, the iris image, and the finger image are all acquired, the quality of the image is measured for the obtained face image, iris image, and finger image, respectively, and the image having the highest quality is used as the biometric information. Or images of some of the face images, iris images, and finger images are acquired, the quality of the images is measured for the obtained face images and / or iris images and / or finger images, respectively, The image is used as biometric information.

In this case, images having the highest quality can be selected using a plurality of methods. For example, an image having the highest resolution among the acquired face image, iris image, and finger image can be selected as biometric information. Alternatively, the image quality may be measured by reflecting the characteristics of each biometric information for each of the acquired face image, iris image, and finger image, and an image having the highest image quality may be selected as biometric information. Here, the measurement of the image quality by reflecting the characteristics of each biometric information is performed by measuring the image quality based on the inherent characteristics of the biometric information of the face (e.g., the outline of the face, the eyes of the face, the sharpness of the mouth, etc.) And measures the image quality based on the intrinsic characteristics (for example, focus, texture, etc.) of the biometric information, such as iris, and measures the inherent characteristics of the biometric information such as fingerprint (for example, ) Of the image quality. The image quality can be individually measured based on the characteristics of each biometric information and the biometric information having the highest image quality can be selected as the final biometric information for authentication.

4 is a diagram illustrating an example of a feature of measuring an image quality of an iris image according to an embodiment of the present invention.

As described above, if one tracking object is selected based on the image acquired according to the image tracking for the object to be recognized and the biometric information (face image, eye iris information, or hand fingerprint) of the selected tracking object is acquired, And carries out an authentication process by comparing it with pre-stored registration information according to a recognition algorithm corresponding to the acquired biometric information.

Accordingly, it is possible to recognize and authenticate faces, irises, fingerprints, etc. using a single device. If necessary, a single authentication process for each of the face, iris, and fingerprint, or a combination using at least two of face, iris, and fingerprint Authentication processing can be performed.

The fan motor unit 113 performs the left and right rotation of the infrared camera 111 to enable tracking of the to-be-recognized person and the tilt motor unit 114 performs the up-and-down rotation of the infrared camera 111, Enable tracing.

The distance measuring unit 120 may be installed at the lower end of the photographing unit 110.

7 is a flowchart of a remote multi-biometric identification method in accordance with an embodiment of the present invention.

When the multibody recognition apparatus according to the embodiment of the present invention is allowed to perform an authentication process for an arbitrary zone and the person to be recognized enters the first setting zone while walking, S100), and performs image tracking on the recognition target (S110). For example, the multi-biometric device operates an infrared camera to perform image tracking to acquire a plurality of images (face image, iris image, fingerprint image, etc.). At this time, the infrared camera blocks the visible light from the outside, and can track the face, eye, and hand position of the object to be recognized. In addition, a plurality of images of the object to be tracked are acquired (S120) by performing image tracking on the object to be tracked such as the face, the eyes, and the hand while adapting the shooting angle and the shooting speed of the infrared camera.

Thereafter, when the to-be-recognized person enters the second setting section, the multi-biometric device selects an image to be traced having the best quality to be obtained based on a plurality of images obtained for the objects to be traced. For example, a face image, an eye image, or a finger image of a hand is obtained by continuously photographing a face, an eye, and a hand according to the image tracking, and the image having the best quality (for example, For example, the image having the highest resolution or the image having the highest recognition rate is selected (S130, S140).

In step S150, an image for authentication processing is acquired through high-resolution / high-speed capturing with respect to the tracking object corresponding to the selected image, and the biometric information of the tracking object (face, iris, or fingerprint) is acquired. In this case, if the target to be tracked is a hand as needed, the fingerprint image of the hand may be obtained separately through a separate fingerprint recognition processing system.

Next, when the to-be-recognized person enters the third setting section, the multi-biometric device performs the authentication process based on the image of the subject to be traced selected in the second setting section (S160, S170). When one of the plurality of tracking objects is selected and the corresponding biometric information (facial image, eye iris information, or hand fingerprint) is obtained in the second setting period, the multi-biometric device corresponds to the acquired biometric information And performs authentication processing based on comparison with pre-stored registration information.

8 is a flowchart of a remote multi-biometric method in accordance with another embodiment of the present invention.

As in the above embodiment, when the to-be-recognized person enters the first setting section while walking (S300), image tracking is performed on the recognition target (S310), and a plurality of images (face image, iris image, Etc.) (S320).

Thereafter, when the to-be-recognized person enters the second setting interval, the multi-biometric device selects a tracking object for authentication based on the plurality of images obtained for the objects to be tracked (S330, S340).

Specifically, the multi-biometric device determines whether face detection is possible based on a plurality of images obtained for the objects to be tracked (S350). If the face detection is possible, it is determined whether iris detection of the eye is possible (S360). For example, a face image, an eye image, or a fingerprint image of a hand is obtained by continuously photographing a face, an eye, and a hand according to a video image tracing, and face detection based on a face image among acquired images . In this case, the iris information acquired from the eye image is a predetermined quality (for example, the iris inherent feature (FIG. 4) as shown in FIG. 4 (Quality based on, for example, focus, texture, etc.)), it is determined that iris detection is possible.

If the iris detection of the eyes is not possible, the face authentication mode is set (S370). If iris detection of the eyes is possible while face detection is possible, the iris authentication mode is set (S380).

On the other hand, if face detection is not possible, the fingerprint authentication mode is set (S390).

When the authentication mode is set, the multi-biometric device acquires an image for authentication processing through the high-resolution / high-speed photography again with respect to the tracking target (face, eye, hand) corresponding to the mode, Or biometric information of a fingerprint can be obtained. In this case, when the fingerprint authentication mode is set, the fingerprint image of the hand may be separately acquired through a separate fingerprint recognition processing system instead of acquiring the hand image.

Thereafter, when the to-be-recognized person enters the third setting period, the multi-biometric device performs the authentication process according to the authentication mode according to the selected tracking object in the second setting period (S400, S410). When the biometric information (face image, eye iris information, or fingerprint of the hand) of the subject to be traced is obtained according to the authentication mode set in the second setting period, the multi-biometric device searches the biometric information And carries out an authentication process by comparing with the stored registration information.
