Description

[0001] The present invention relates to an electronic safe box having a secure function of biometric data,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a locking device for a safe using biometric information, and more particularly to a locking device for a safe using biometric information, which is characterized by a fingerprint sensor and a finger vein recognition sensor.

Since a safe stores valuables such as cash or securities, precious metals, confidential documents, and so on, various studies have been made on safety devices of safes.

However, in such a conventional safe, it is only intended to prevent the safe from being lost due to the destruction of the safe itself or theft of the safe itself. As is well known, the opening and closing of the door opening / .

1 and 2, a door 10 provided on the front surface of the safeguard 1 according to an embodiment of the present invention includes a door handle 11 and a fingerprint sensor 20 is provided on one side of the case 1, and a signal generating unit 70 for emitting an alarm signal is provided on one side of the case 1. A door opening / closing device 60 is provided at the side end of the door provided with the door handle 11 and at the end of the body in contact therewith.

Inside the safe 1 is stored a data processing unit 30 for processing fingerprints recognized from the fingerprint sensing unit 20 as data and a fingerprint data storage unit for storing the fingerprint data in an administrator having authority to open and close the safe 1 The fingerprint data processed by the data processing unit 30 and the fingerprint data stored in the memory unit 50 are compared with each other and if the fingerprints match the fingerprint data stored in the memory unit 50, And a controller 40 for controlling the door signal generator 60 to generate an alarm signal through the door signal generator 70 while maintaining the closed state of the door opener 60 when both the fingerprints do not coincide with each other It is built-in.

However, in the method of authenticating only the fingerprint when opening and closing the door as described above, the fingerprint recognition technology is small in size and can be mass-produced at low cost. Also, it shows relatively good performance in terms of accuracy and speed of recognition. However, fingerprints are exposed outside the body and are likely to be stolen and deformed by sweat, which can affect recognition performance.

In order to overcome and overcome the disadvantages of fingerprint recognition techniques described above, finger vein recognition technology has been developed.

The finger vein recognition technology refers to a technique for identifying an individual using a finger vein pattern image acquired through infrared rays. Human veins are located in complex shapes directly beneath the skin. According to various studies, the pattern of the veins is different for each individual, and it is known that the pattern does not change with age.

The fingerprint recognition technology has the following advantages. That is, since the vein is inside the body, there is little risk of theft or forgery, and the state of the finger surface has no effect on the recognition. In addition, it is possible to construct a noncontact type device with high convenience for the user by using infrared rays. Since the finger pattern can be stably and relatively clearly searched, a camera having a low resolution can be used to obtain a small fingerprint image have. That is, fingerprint recognition technology can provide balanced performance in terms of security and convenience.

Due to these advantages, finger vein recognition technology is more difficult than fingerprint, iris, face and voice recognition technology for counterfeit modulation. Therefore, biometric authentication device with higher safety can be realized and miniaturization is possible. .

However, according to the authentication method of the fingerprint or the fingerprint, the probability of false recognition of the fingerprint is 1/10 billion, and the fingerprint is known to be about 1 / 100,000, and the probability varies depending on the design technique.

Accordingly, when a technique of authenticating a fingerprint with a fingerprint authentication and simultaneously authenticating the fingerprint is applied, the probability of the inviscans is simply an astronomical number, and there is no person having the same fingerprint and fingerprint pattern on the earth It is estimated.

    }

    return 0;

}

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.

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. 12 to 14, a registration request is made in the fingerprint and finger vein recognizer as a step of registering fingerprint and finger vein (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.
