[0001] APPARATUS FOR AUTHENTICATING USER USING HYBRID BIOMETRICS INFORMATION [0002]

The present invention relates to a user authentication apparatus using complex biometric information, and more particularly, to a user authentication apparatus using complex biometric information that enables a user to easily acquire a plurality of biometric information from a user.

As interest and research on system security have been actively developed, interest in user authentication has been increasing day by day.

As a conventional method for user authentication, a method using a password has been widely used. The password input method means a method of authenticating a user by allowing a user to input a password composed of numbers, characters, or a combination thereof registered in advance.

However, such a password method has a problem in that the security is not high and damages such as leakage of personal information are worried. For this reason, there has been a method of authenticating a user by using biometric information such as fingerprint and iris recognition, which have higher security.

Fingerprint recognition, which is widely used as a biometric authentication method, is the simplest and cheapest biometrics technology, and has a relatively high recognition rate of error rate within 0.5% and fast verification speed within 1 second.

However, since about 5% of the population can not perform fingerprint authentication due to fingerprint damage, biometric information may be leaked when copying the fingerprint traces left on the fingerprint scanner glass, There is a problem that accurate authentication can not be performed when there is dirt or the like.

The iris recognition method recognizing the user using the iris pattern can extract more feature points than the fingerprint, so that a higher complement can be expected. However, the recognition rate in the outdoor is considerably lowered. And the difficulty of being accepted by the public.

As described above, biometrics technologies widely popularized by the public are disadvantageous in that, when user authentication is performed using only one biometrics technology, the user may be inconvenienced.

The user authentication apparatus 100 using complex bio-information according to an embodiment of the present invention includes a gripper 110, an iris recognition unit 130, and a controller (not shown).

In FIG. 1, only the components related to the embodiment of the present invention are shown. Accordingly, it is to be understood that one of ordinary skill in the art to which the present invention belongs may further include general components other than the components shown in FIG.

The gripper 110 allows the user to grasp the user authentication apparatus 100 using the complex biometric information in the form of a bar type. 1, the grip portion 110 is a bar type. However, the shape of the grip portion 110 is not limited to the shape of the grip portion 110, and may be formed in other general shapes such that the grip portion 110 can be grasped by a user.

The gripper 110 according to an embodiment of the present invention includes a fingerprint scanner 111. The fingerprint scanner 111 includes a capacitive array sensor that acquires a fingerprint image in contact with a chip using a silicon chip, an optical sensor that acquires a fingerprint image using total reflection of light incident on the prism from the light source (CCD) / CMOS sensor (CCD) that acquires fingerprint images using a CCD / CMO-S sensor, a CCD sensor that acquires a fingerprint image by measuring the temperature of a finger, / CMOS sensor), an ultrasonic sensor (ultrasound sensor) that converts ultrasonic waves to fingers placed on a contact surface and converts the reflected sound waves into electrical signals to obtain a fingerprint image, A tactile sensor, or the like. However, the manner of implementing the fingerprint scanner 111 is not limited thereto, and other general-purpose sensors may be used.

The control unit (not shown) performs user authentication using at least one biometric information of the user's fingerprint information acquired from the fingerprint scanner 1110 and the iris information acquired from the iris recognition unit 130.

Here, the meaning of performing the user authentication may mean that the biometric information acquired by the above-described method is transmitted to another electronic device stored with the fingerprint recognition algorithm or the iris recognition algorithm and compared with the previously registered user biometric information. Alternatively, the user authentication apparatus 100 using the complex bio-information according to an embodiment of the present invention may store fingerprint recognition algorithm or iris recognition algorithm and perform user authentication using the fingerprint recognition algorithm or the iris recognition algorithm.

As described above, when a plurality of biometric sensors are provided in one user authentication apparatus, a plurality of biometric information can be acquired at one time, and the user convenience can be achieved.

2 and 3 are views for explaining a process of simultaneously acquiring a plurality of biometric information through a user authentication apparatus using complex biometric information according to an embodiment of the present invention.

In order to capture a user's own iris image, it is necessary to close the user authentication apparatus 100 using the complex biometric information provided in the iris recognition unit 130 as shown in FIG. 2 do.

At this time, the fingerprint scanner 111 according to one embodiment of the present invention is provided on the surface of the iris recognition unit 130 facing the same direction as the direction in which the iris recognition camera 130 photographs the iris of the user, .

Accordingly, when the user grasps the gripper 110 to capture his or her iris image, the end of the thumb comes into contact with the fingerprint scanner 111 as shown in FIG. The fingerprint scanner 111 can acquire the fingerprint information of the user's thumb.

Accordingly, the user can transmit a plurality of pieces of biometric information through one device without transmitting the fingerprint information and the iris information through a separate user authentication device for user authentication.

4 and 5 are views for explaining a user authentication apparatus using complex biometric information according to another embodiment of the present invention.

At least one guide groove 113 capable of receiving the user's finger may be formed on the grip 110 according to an embodiment of the present invention. Four guide grooves 113 may be formed to accommodate the remaining four fingers except for the thumb.

5, when the user grasps the gripper 110 while positioning the remaining four fingers except for the thumb along the guide groove 113, the iris recognition unit 130 faces the user's face, Can be easily photographed.

At this time, the fingerprint scanner 111 may be provided on the surface of the guide groove 113 where the user's finger contacts. The fingerprint scanner 110 may be provided for each guide groove 113 as shown in FIG. 4, and may be provided only on the surface where the index finger contacts.

As described above, when the guide groove 113 is used, the user's satisfaction can be enhanced by increasing the grip feeling, and the error rate can be lowered by allowing the user's finger to touch the fingerprint scanner 110 naturally.

6 and 7 are views for explaining a user authentication apparatus using complex biometric information according to another embodiment of the present invention.

The grip portion 110 according to one embodiment of the present invention may include a receiving groove 115 formed at the lower end as shown in FIG. At this time, the fingerprint scanner 111 may be provided on the inner surface of the receiving groove 115.

7, when the user inserts the finger into the receiving groove 115 and moves the iris recognition unit 130 to the eye position of the user, the fingerprint scanner (not shown) provided on the inner surface of the receiving groove 115, The user 111 can acquire fingerprint information of the user.

In the embodiment shown in FIG. 7, the user inserts only one finger into the receiving groove 115, but the receiving groove 115 may be formed so that a plurality of fingers can be inserted.

In addition, the receiving groove 115 may be formed on the side surface or the entire surface of the grip 110 as well as the bottom.

8 is a diagram for explaining a method of setting a security level according to another embodiment of the present invention and selecting biometric information to be used for user authentication according to a set security level.

The user authentication apparatus 100 using complex biometric information according to an embodiment of the present invention may further include a switching unit 150 that can set a security level.

The security of the security system utilizing the biometric information can be changed according to the characteristics of the biometric information. For example, in the case of a fingerprint, which is a representative biometric information authentication method, the rejection rate is 0.1 to 0.5% and the acceptance rate is 0.001 to 0.01%. On the other hand, in the case of user authentication using iris widely used for user authentication, the rejection rate is 0.0001% ~ 0.1% and the other acceptance rate is 0.000083% ~ 0.0001%, which is higher than the method using fingerprint.

Therefore, when biometric information to be used for user authentication is selected according to the security level preset by the user, the user convenience can be enhanced.

Here, the security level is a relative concept compared with other security levels. For example, the level of the first security level is the highest as compared with the other security level classes, the second security level is lower than the security level of the first security level but higher than the third security level having the lowest security level . ≪ / RTI >

That is, the security level of the security level described below can be lowered in the order of the first security level-> the second security level-> the third security level.

The control unit according to an embodiment of the present invention can generate a control signal for activating at least one of the corresponding iris recognition unit 130 and the fingerprint scanner 111 through the switching unit 150. [

For example, when the switching unit 150 is set to the first security level requiring the highest security, the controller activates both the fingerprint scanner 111 and the iris scanner to acquire the user's fingerprint information and iris information have.

The acquired biometric information may be transmitted to another electronic device and used to perform a user authentication procedure. Alternatively, the fingerprint recognition algorithm and the iris recognition algorithm stored in the user authentication device 100 using complex biometric information according to an embodiment of the present invention An authentication procedure can be performed.

On the other hand, when the switching unit 150 is set to be higher than the first security level requiring the highest security and higher than the second security level higher than the third security level requiring the lowest security, Only the iris information of the user can be acquired.

Generally, since the user authentication method using iris is superior to the user authentication method using fingerprint, when the switching unit 150 is set to the second security level, the iris recognition unit 130 ) Is activated.

Finally, when the switching unit 150 is set to the third security level requiring the lowest security, the control unit may generate a control signal for activating only the fingerprint scanner 111. [

In the case of the user authentication method using the fingerprint information, since the security is low, but the error rate is low and the recognition speed is high, only the fingerprint scanner 111 is activated to acquire fingerprint information only and then the user authentication procedure is performed using the fingerprint information.

As described above, if the biometric information used for user authentication is different according to the operation of the switching unit 150, not only optimal security can be ensured but also an error rate can be lowered to achieve user's convenience have.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. Therefore, the disclosed methods should be considered from an illustrative point of view, not from a restrictive point of view. The scope of the present invention is set forth in the appended claims rather than the foregoing description, and all differences within the scope of equivalents thereof should be construed as being included in the present invention.
