Description

  The present invention relates to a safe deposit box system in which a financial institution such as a bank or a securities company lends a part of a safe to a customer, and in particular, recognizes the individual's biological characteristics to determine whether the customer is the only one, and identifies only the identified customer. The present invention relates to a safe deposit box system using biometric recognition technology that enables a user to use a safe.

  Generally, a safe deposit box is a type of safe deposit in which a financial institution such as a bank or securities company lends a portion of the safe with a key, and stores securities, precious metals, important documents, etc. This is a one-dimensional high-level financial service that has become inaccessible. Currently, domestic financial institutions mainly provide VIP customers in the form of services, or receive and provide a certain amount of loans to customers who want to use it. Is being done.

  In such a safe box, a large number of safe boxes are provided in a plurality of safe boxes, and each safe box is opened and closed by a key or a dial.

  However, the conventional safety box as described above has a disadvantage that a key used for opening and closing is highly likely to be lost and can be stolen, so that even a person other than the person himself / herself cannot identify the key.

  In the case of dialing, the operation is cumbersome, and the user may forget the dial number required for the dialing operation.Like a key, there is no identification function even when disclosed to others, so lending against the will of the person himself There was a disadvantage that the safe was used.

  In addition, there is a problem that the customer information on the breakdown of use of the safe deposit box cannot be determined and cannot be managed.

  The present invention has been devised in order to solve the above-described problems of the conventional safe deposit box system, and uses a blood vessel such as a face or a hand which is an invariable element in personal identification for use of the safe box. Identification of a person or another person by using biological characteristics such as a certain vein pattern, fingerprint, iris, cornea, DNA pattern, etc., prevents other people from plagiarizing the card and, from the manager's point of view, It is an object of the present invention to provide a safe deposit box system using a biometric recognition technology that enhances the convenience and security of customer management by making the use status of a safe into a database.

  In order to achieve the above object, the safe deposit box system using the biometric recognition technology according to the present invention compares the biometric characteristics of a registered customer with the biometric characteristics of a current user to determine whether the user is the same person. A biocharacteristic recognizer that generates an authentication packet; a microcontroller that receives and decodes the authentication packet transmitted from the biocharacteristic recognizer and sends out an electric signal for opening the safe door; An electronic lock for opening and closing the safe door while operating, and an LED that is turned on or off in accordance with the open / closed state of the electronic lock; and a number of safe boxes with the electronic lock attached.

  As described in detail above, the safe deposit box system using the biometric recognition technology of the present invention opens and closes the safe door of the safe box using unique and invariant biological characteristics such as face, fingerprint, and vein pattern. As a result, there is an advantage that the security is improved without duplication possibility, the convenience of use is enhanced without being bothersome, and the information of the usage status is stored in a database, so that efficient customer management and system management can be performed.

  Hereinafter, a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

  FIG. 1 is a schematic configuration diagram showing the configuration of a safe deposit box system according to the present invention.

  As shown in the drawing, the present invention provides a biological characteristic recognizer 100 for recognizing biological characteristics, a microcontroller 200 for controlling opening and closing of a safe door according to a control signal of the biological characteristic recognizer 100, and a communication between the microcontroller 200. A safe box 300 provided with an electronic lock (LOCK) for opening and closing the safe door in response to a control signal.

  In particular, the biometric characteristic recognizer 100 is provided with an output device 110 so as to output the current state of use.

  The biometrics recognizer 100 is preferably formed of a kiosk in order to provide a user with a convenient interface using a touch screen.

  The kiosk is a term referring to a street stall derived from Turkey and generally refers to a terminal that sells digital information.

  The kiosk is a computer-human interactive system that can provide the latest information in real time through voice and image media. The range of medical services and reservations for hospitals, etc., traffic information, geographic information, sightseeing spots and accommodations, reservation and sale of various tickets, unmanned sales of convenience stores, academic affairs management, unmanned postal processing, etc. are rapidly increasing. I have.

  Such a kiosk includes a storage device for storing the biometric characteristics (eg, fingerprint, face, vein pattern, iris, cornea, and DNA pattern) of a registered customer (user), and a recognition device for recognizing the biometric characteristics of the customer. (A biometric recognition module), a comparator equipped with software for comparing and recognizing the biometric characteristics of the recognized user with the biometric characteristics of the customer stored in the storage unit, and when it is determined that the customer is a registered customer A controller such as a microprocessor for generating an authentication packet and controlling the transmission to the microcontroller 200 and a monitor for displaying the progress to the user are provided.

  In addition, the kiosk can be provided with a management module for an administrator when the vault is not in use, for example, by checking items such as system operation check, safety box status check, locking test, etc., and periodically checking the items. Then, the result can be output through the output device 110 or displayed on the screen of the manager and stored in a separate memory at the same time, so that the result can be output when necessary, and the record of registration and use of the customer can be managed. It is easier to do.

  As shown, the biocharacteristics recognized and determined by the kiosk used as the biocharacteristic recognizer 100 include, as illustrated, a vein pattern of a user having invariance and individuality (vein patterns within a predetermined specific area). Grasping characteristics such as distribution characteristics indicating the branch points, the number of branches at the branch points, and the connection relationship between the branch points), face (grasping the characteristics such as skin color and face outline in the selected area and positional information such as eyes, nose, mouth, etc.) ), Fingerprints (characteristics such as protrusions of fingerprints, branch points, end points, break points, etc. of protrusions centered on the fingerprints), iris of eye, cornea or DNA pattern.

  At this time, it is possible to recognize the user's face with a general CCD camera, but it is preferable to use an infrared camera to recognize veins, and it is preferable to use an optical module for fingerprints. Since the recognition process and the comparison judgment relationship are well known, a detailed description will be omitted.

  On the other hand, a password selection mode can be provided as protection means in case the biometric characteristics of the customer cannot be used, such as the death of a registered customer, in the biometric characteristic recognizer 100.

  This can be easily handled by programming the initial selection mode through the kiosk so that any one of the biometric characteristic recognition selection mode and the password selection mode can be selected and used.

  As shown in FIG. 2, the microcontroller 200 has a bio-characteristic recognizer through an RS-232 (Baud Rate: 9600 bps, Data Bit: 8 Bit, Stop Bit: 1 Bit, Parity: No Parity, Over Time: User Define) serial port. A data processing unit 210 for exchanging data with the data processing unit 100; an opening / closing signal output unit 220 for outputting an electric signal for opening / closing a safe of a safe in accordance with a signal received by the data processing unit 210; Open / close sensing unit 230 for detecting whether the device is opened or closed by detecting a control signal and a signal controlling unit 240 for controlling a data flow.

  It is desirable that the data processing unit 210 communicates with 5 bytes when receiving a command signal from the biometric characteristic recognizer 100 and communicates with 3 bytes when outputting a response signal.

  For example, a command signal which is an authentication packet when it is confirmed that the customer is transmitted by the structure shown in FIG.

  Here, (1) in FIG. 4 means 1 Byte (= 8 bits), STX is a start flag, expressed as 5AH as a hexadecimal value (Hexa) (hexadecimal), and as 01011010 as a binary number. Is represented by 8 bits to form a total of 1 Byte, and such 5AH is set as a value indicating the start.

  Further, CMD is a command value. For example, 31H (0011 0001) releases the lock (L0CK); 37H (0011 0111) performs a lock test; 35H (0011 0101) checks the lock state; 39H (0011 1001) ) Can be defined and used to perform commands such as LED checks.

  If the safe number is normally 4 digits (10,000 units), it can be expressed as a hexadecimal value by dividing it by 2 digits. For example, the safe at the 0001th position is 00H + 01H: The safe at the 1000th position is It can be expressed and recognized as 10H + 00H.

  In addition, Check sum is a value obtained by adding the previous 4 bytes. If the value is 1 Byte or more, the value larger than that is processed by truncating, and the error is checked by combining the bit strings.

  A response signal to such a command signal is transmitted in 3 bytes having a structure as shown in FIG.

  Here, STX has the same meaning as in the case of the command signal, and a response 1 Byte is a response (RESPONSE) corresponding to each command value, for example, 31H (lock release successful); 32H (lock when CMD is 31H). 33H (Lock open when CMD is 35H); 34H (Lock closed); 35H (Lock test normal); 36H (LED ON); 37H (LED OFF); 50H (Lock error); AOH (Check sum error) ) Can be defined as a response value to process the signal.

  The open / close signal output unit 220 is a unit that decodes a command signal for opening or closing the safe door among the command signals of the data processing unit 210 and sends out an electric signal for opening or closing the safe door.

  For example, when the biometric characteristic recognizer 100 transmits a safe door opening request signal, the data processing unit 210 receives the signal, and the open / close signal output unit 220 opens the safe door under the control of the signal control unit 240 after receiving the signal. Output an electrical signal.

  The open / close sensing unit 230 detects when the user closes after opening each safe door of the safe box 300 and sends a signal indicating that the safe door of the safe box 300 is closed through the data processing unit 210 to the above-described structure. This is a part to be transmitted to the biological characteristic recognizer 100 as a response signal.

  As such a microcontroller 200, for example, a ks88 series which is an 8-bit MCU (Micro Controller Unit) can be provided, which provides 81 electronic lock ports, and connects up to 50 controllers to one kiosk. It can also be configured to be used in connection with.

  The safe box 300 is provided with an electronic lock that opens and closes the safe door by the above-described electric signal processing. The electronic lock is preferably a solenoid that operates at, for example, 24 V. The structure of the safe is well-known, and a description thereof will be omitted. I will.

  At this time, it is possible to automatically open and close the safe door of the safety box 300 only through the electronic lock. However, it is preferable to hold the primary unlocked state through the electronic lock and then use the key to finally open the safe door. Let it. As a result, security is further improved.

  In addition, it is preferable that an LED is provided in each of the electronic locks so that the LED is turned on at the time of processing the release signal so that the user can immediately identify which safe requested the release.

  The operation relationship of the present invention having such a configuration is as follows.

  With reference to FIG. 3, an example of face recognition among the biological characteristics according to the present invention will be described.

  Except for the point where the biometric characteristic used in the operation relation of the present invention described later is a face and whether to input a safe number first or to select a biometric recognition mode first, the remaining control processes are fingerprint recognition and The vein pattern, iris, cornea, and DNA pattern recognition are all the same.

  First, the user approaches the biological characteristic recognizer and selects a biological characteristic selection mode, for example, a face recognition mode (S11).

  Next, the user inputs the safe number and determines whether the safe is lent (S12, S13).

  If the safe is not lent, the system returns to the initial mode after outputting a message such as "The safe is not lent", and if the safe is lent, the customer's image ( (Face) is input (S21, S14).

  The input image is converted into digital data through a frame grabber and converted into data to be used for authentication.This data is stored in a database (repository) and the registered customer's biometrics (face) and a comparator are used. And whether the user is a registered user is determined (S15, S16, S17).

  The algorithm of the comparator used at this time, for example, compresses and detects 128 feature points of the face centered on both eyes into 512-byte data, thereby comparing the registered customer face image with the data value. And performing comparative authentication in accordance with the set separation degree.

  If the result of the above determination is that the user is not an authorized user, the message "Authentication failed. Please execute the authentication process again" is output, and then the screen returns to the initial screen again. Generates a 5-byte authentication packet and transmits it to the microcontroller (S22, S18).

  When a command signal, which is an authentication packet, is received, the microcontroller sends a 24V electric signal to the electronic lock of the safe box of the safe in accordance with the command value to open the electronic lock (solenoid) and simultaneously activate the LED. Is turned on, and if the opening and the lighting of the LED are normal, the normal opening by the response signal of 3 bytes is displayed on the touch screen of the kiosk, which is a biometrics recognizer, by the microcontroller and becomes usable (S19). ).

  Thereafter, when the safe door is closed and the LED is turned off, the completion of use is reported by the signal processing of the microcontroller that detects the opening and closing, and the mode is returned to the initial mode (S20).
