Description

[0001] INTEGRATE MODULE CHECKING ALGORITHM OF FINGER VEIN AND FINGERPRINT AT THE SAME TIME [0002] FIELD OF THE INVENTION [0003]

The present invention relates to an input / output integration module for simultaneously linking fingerprint and fingerprint algorithms. In particular, fingerprints and fingerprints that are designed to be applied to national intelligence agencies and financial transaction systems that require extreme security are authenticated simultaneously by authenticating fingerprints and fingerprints simultaneously. And an input / output integration module for simultaneously linking Mac algorithms.

If the fingerprint and the fingerprint are authentic, the stereoscopic authentication device distinguishes men and women and uses two fingers to fingerprint the fingerprint, and additionally authenticates the fingerprint. By keeping the biometric authentication of the individual as much more unique information than the existing authentication environment, Device technology.

Biometric information unique to each person has the advantage that it can not be separated by a person.

In the case of fingerprint recognition, frequent authentication errors are pointed out, such as when moisture or foreign matter is present on the finger or when the finger skin is damaged or deformed, and the fingerprint can easily be forged and copied.

The false recognition rate of fingerprint recognition is about 5%, for example, it does not recognize fingerprints of about 5 out of 100 people.

On the other hand, in the case of the red - light recognition technology, when the user wears a color content lens or has undergone LASIK or LASIK surgery, the authentication time or authentication time is long and the error is caused by distance and angle.

Fingerprint authentication technology is superior to biometrics technology in that it provides superior biometric information in all aspects, such as inferiority composition, false acceptance rate, false rejection rate, failure to enroll rate, It was announced.

The finger vein authentication technique is a technique of recognizing a vein pattern by transmitting a near infrared ray to a finger. Because it authenticates the inside of the blood vessel, it can not be tampered with, and if necessary, it can utilize the finger vein pattern of the dead person.

This fingerprint authentication technology combines a hardware device technology for obtaining a finger vein image using a CCD camera and a software technique for filtering a finger vein image using a pattern processing program or extracting vein patterns .

However, there are two drawbacks to the fingerprint authentication device, the first being the possibility of false recognition. It is known that one finger per 100,000 people or one per million people perceive the same vein blood vessel shape according to the finger vein processing algorithm. Therefore, despite the excellence of the fingerprint authentication technology, there was a vulnerability that the two-dimensional finger vein shape in the finger could not be authenticated correctly by only the shape of the finger vein for two persons having the same chance.

The second disadvantage is that it is necessary to compare the similarities of the two phallocentric photographs and to compare them after overlapping the two shapes as much as possible. In other words, the similarity of blood vessels in two veins is compared with reference to relative coordinates, not relative to absolute coordinates, which can be a deviation factor that hinders accurate recognition.

In order to solve such a problem, the technology as shown in Fig. 1 was invented.

1, a scan panel 105 made of a transparent material such as glass or acrylic is installed on the upper part of the object accommodating portion 101. [ The user places the finger object on the scan panel 105 to start finger vein authentication. When the finger vein authentication by the device is started, the infrared light source unit 140 and the line-of-sight light source unit 141 irradiate infrared rays and visible rays toward the finger object.

Then, the CCD infrared camera and the CCD line-of-sight camera shoot the finger vein fingerprint and the finger vein fingerprint of the irradiated finger, respectively.

In the device 100 of the prior art, two CCD cameras 130 and 131 are incorporated.

The finger vein camera 130 is installed inside the object accommodating unit 101 and captures the finger vein of the object toward the scan panel 105. [ At the same time, the finger-joint fingerprint camera 131 is installed in the same object accommodating portion 101 to photograph the finger-joint fingerprint of the object.

The infrared light source unit 140 irradiates infrared light toward the object accommodating portion. Preferably one or more LEDs emitting infrared light having a wavelength of 630 to 1,000 nm suitable for imaging the finger vein image. In addition, preferably, an optical filter is provided to remove the light noise.

The line-of-sight light source unit 141 irradiates visible light toward the object accommodating portion. And may be constituted by one or more LEDs by emitting ultraviolet light of a suitable wavelength for photographing a finger-joint fingerprint of the finger surface.

In one embodiment of the present invention, one infrared light source unit 140 and one line-of-sight light source unit 141 for irradiating infrared light and visible light to the object accommodating unit may be provided.

Moreover, in a preferred embodiment of the present invention, the vein camera 130 acquires a vein image for a two-finger object.

However, even if two fingers are used in the finger vein authentication device, it is necessary to compare two similarities of the two finger vein photographs, which are the first defect and the second defect, And there was a problem that the recognition rate of only one finger vein could not be covered.

In addition, biometric information is superior in all respects such as internal structure, false acceptance rate, false reject rate, failure to enroll rate, authentication time, Mac authentication technology is known.

The finger vein authentication technique is a technique of recognizing a vein pattern by transmitting a near infrared ray to a finger. Because it authenticates the inside of the blood vessel, it can not be used for modulation, and it can not utilize the finger pattern of the dead person. However, there is a problem in that it may have the same pattern of about 10 million or more.

It is an object of the present invention to provide a fingerprint authentication apparatus and a fingerprint authentication method capable of simultaneously reducing a false recognition rate of a fingerprint and reducing an error in determining similarity of a blood vessel to a finger vein by simultaneously authenticating fingerprints and fingerprints, And an authentication method that can easily recognize the information with a single finger.

Furthermore, in order to narrow the error range of the fingerprint or the fingerprint recognition rate, it is necessary to reduce the recognition rate of each fingerprint and to determine whether the fingerprint or fingerprint is authenticated by the form of the combination, It has its purpose.

The RO 8 line is a serial 232 communication transmission port, and functions to transmit a command. It is linked with the integration module U1.

Next, the fingerprint and fingerprint input and USB output integration module U1 will be described.

The D1 / TX1 line of the integration module U1 is a serial 232 communication transmission port and functions as a data transmission function to a computer. The D0 / RX2 line is a serial 232 communication reception port. , GND line 4 is the ground of 0V as a voltage reference and D2 line 5 is the serial 232 communication transmission line of the fingerprint module (U2).

}

The algorithm is an algorithm that accepts a fingerprint authentication code and a fingerprint authentication code from the integration module U1 and allows an authentication code only when the fingerprint and the low vein are the same person.

The following is a more detailed description.

If other fingerprint code and fingerprint code are invalid or do not match, an error code of 0 is output.

The following describes the procedures for registering, authenticating and deleting fingerprints and fingerprints from the self-archiving recognizer or bank.

First, as shown in FIGS. 17 to 19, registration of a fingerprint and a fingerprint is performed by a fingerprint and a fingerprint recognizer (S311).

When there is a registration request in the fingerprint and fingerprint recognizer, the fingerprint and finger vein are scanned first by the finger of the person to be registered (S312).

Next, the fingerprint and the finger vein are scanned to the recognizer by the finger of the person who wants to register the fingerprint and the fingerprint of the person who intends to register after the first registration in the recognizer of the finger vein (S313).

Next, the fingerprint and finger vein are scanned by the finger of the person who intends to register the fingerprint and finger vein to the recognizer after the first registration in the fingerprint and fingerprint recognizer (S314).

In order to measure the accuracy of the registration of the fingerprint and finger vein in the recognizer, it is determined whether all three scanned images match (S315).

If the three fingerprints and the fingerprint registered in the recognizer do not coincide with each other and the three scanned images do not coincide with each other, the process is resumed. If all the scanned images match, the registration is completed (S316).

This process is performed three times to register the image of the correct fingerprint and finger vein.

Next, authentication of the fingerprint and the fingerprint is performed, and the fingerprint and fingerprint recognizer make an authentication request (S321).

The fingerprint of the fingerprint and the image of the finger vein are scanned in the fingerprint and fingerprint recognizer (S322).

In step S323, the image of the fingerprint and the finger vein scanned by the finger of the registered person is compared with the image of the fingerprint and finger vein.

In step S324, it is determined whether or not the scanned image matches the fingerprint and the fingerprint recognizer.

If all of the scanned images in the fingerprint and finger vein recognizer do not coincide with each other as described above, they are restarted. If all the scanned images match, the authentication is completed (S325).

The following is a step of deleting the registration of the fingerprint and the fingerprint, and the deletion request is made from the fingerprint and the fingerprint recognizer (S331).

The code of the party to be deleted is input to the fingerprint and fingerprint recognizer (S332).

It is determined whether the image of the code to be registered is deleted from the recognizer of the fingerprint and the finger vein (S333).

If the scanned image is not deleted from the recognizer of the fingerprint and the finger vein, the authentication is restarted. If the scanned image is deleted, the authentication is completed (S334).

As described above, when the fingerprint and the fingerprint are managed by a method of registering, authenticating and deleting the fingerprint and the fingerprint of the fingerprint and the fingerprint of the fingerprint and the fingerprint, the recognition degree of the fingerprint and fingerprint is further increased and the operation is simplified.

The scope of protection of the present invention is not limited to the description and the expression of the embodiments explicitly described in the foregoing.
