Hereinafter, a fingerprint authentication device having a fingerprint image display function according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a fingerprint authentication device for access confirmation according to an embodiment of the present invention, Figure 2 is a block diagram of a network of the fingerprint authentication device according to an embodiment of the present invention.

As shown in FIG. 1, the fingerprint authentication apparatus for confirming access according to an exemplary embodiment of the present invention includes a controller 110, an image of a visitor captured image display unit 120, a key input unit 130, a fingerprint recognition unit 140, and a memory unit. 150, an Ethernet communication unit 160, a door control unit 170, an accessor image pickup unit 112, and an accessor image capture image comparison unit 114.

The person image capture image display unit 120 displays a necessary matter during the authentication process, and outputs the image image of the person to be displayed so that the person can check the fingerprint image of the person, for example, the LCD is preferred. The person captured image display unit 120 outputs a person captured image obtained by the person image capture unit 112 according to a control signal of the controller 110.

The key input unit 130 is a device for inputting a variety of key signals according to the key operation of the person, it is provided with a variety of setting keys including a fingerprint image recording key, the person in advance fingerprints the fingerprint image of the person using the fingerprint image recording key It records and stores in the authentication device 100, and sets the environment of the fingerprint authentication device 100 using various setting keys.

The fingerprint recognition unit 140 includes a fingerprint input unit 142 to which a person's fingerprint is input, and a biometric sensor 144 that determines whether the input fingerprint data is due to a fake fingerprint made of silicon or the like. The fingerprint recognition unit 140 scans a fingerprint input from the fingerprint input unit 142 to generate a fingerprint image, and generates and outputs image data from the fingerprint image.

The fingerprint image obtained by the fingerprint input unit 142 refers to a still image of one frame such as an ID picture, and the size of the fingerprint image is slightly larger than a thumb of a normal adult. The fingerprint image is divided into the actual fingerprint image and the background image which is the other part. Fingerprint data means that only the actual fingerprint image except for the background image is extracted from the fingerprint image, and the feature points (ridgeline, triangular point, center point, valley, weak point, branch point, etc.) of the fingerprints are extracted and dataized.

The fingerprint input unit 142 recognizes a person's fingerprint and generates a fingerprint image of the fingerprint. When light is irradiated from a light source (not shown) installed therein, the light is input to a pad (not shown) of the fingerprint input unit 142. After the path is changed by being reflected by the finger interviewed by), it is input to an image sensor (not shown). The image sensor generates a fingerprint image corresponding to the input light and transmits the fingerprint image to the fingerprint recognition unit 140. The fingerprint person 140 extracts feature points from the fingerprint image to generate fingerprint data, and outputs the generated fingerprint data and the fingerprint image to the outside (for example, the controller 110).

The biometric sensor 144 detects a change in capacitance according to a person's finger contact and identifies whether the fingerprint data is fingerprint data due to a forged fingerprint by silicon or the like, and is installed adjacent to the fingerprint input unit 142.

The biometric sensor 144 detects a change in capacitance automatically when a person touches a finger to the fingerprint input unit 142 and changes its voltage value. The biometric sensor 144 inputs the voltage value to the controller 110 to control the controller ( 110 determines whether the fingerprint is a fake through the voltage value. For reference, a process of determining whether the controller 110 is a fake fingerprint when inputting fingerprint data will be described later.

The memory unit 150 stores various data necessary for authentication and various programs necessary for operation. When the power of the fingerprint authentication apparatus 100 is turned on, the boot loader stored in the flash ROM 154 is stored. Copied to the RAM 152 and automatically executed, the controller 110 performs an overall operation of the fingerprint authentication device 100 such as an authentication process and data communication. Here, a plurality of fingerprint data may be recorded per person, and the number of recorded fingerprint data may be recorded up to 10 for each finger.

In addition, the memory unit 150 further includes an access person captured image storage unit 151. The guest image capture unit 151 stores an image of the person captured by the image capture unit 112. At this time, the extension of the saved file is a still image such as JPG, TIF, or BMP. The file name is year, month, date. * Or year, month, date, ID. *, And the size is about halftone photo. The accessor image file may be transmitted and recorded by the controller 110 to the central control server 200 connected to the network 300 of FIG. 2 through the Ethernet communication unit 160 described later. Therefore, the administrator can check only when the accessor image capturing image file recorded in the central control server 200 determines when the accessor entered (when and when).

The person imaging unit 112 images the person using the control unit 110. As the image capturing unit 112, a CCD camera may be generally used, and an infrared CCD camera may also be used so that it can be used at night. The accessor image pickup unit 112 images the accessor only when the fingerprint data output by the fingerprint recognition unit 140 matches the fingerprint data in the accessor information stored in the Flash ROM 154.

As described above, when the person image pickup unit 112 picks up the person, the control unit 110 stores the person image captured in the person image capture unit 151 as the year, month, date and time. * Or year, month, date and time ID. *. Next, when there is a new person, the person imaging unit 112 captures a new person in the same manner as above, and sets the person captured image as the year, month, date, time, or year, date, time ID. * To the person captured image storage unit 151. The data is stored and recorded in the central control server 200 through the Ethernet communication unit 16. Next, the controller 110 compares each of the image of the person stored in the image of the person image storage unit 151 by the person image capture image comparison unit 114 with each other. In this case, a device including a commercially available algorithm for comparing the images with each other may be used, and may be implemented programmatically. If the particle-captured image comparator 114 determines that the same image of the image of the same person is not present, or that the image of the image of the image of the same person is not greater than 80%, the controller 110 displays the newly input image of the image of the image of the same person. The time ID. * Is recorded in the central control server 200 through the Ethernet communication unit 16. However, if the particle-captured image comparator 114 determines that the same image of the image of the same person is present or that the image of the image of the image of the user is the same, or more than 80%, the controller 110 controls the newly inputted image of the image of the user to enter the Ethernet communication unit 16. Through the central control server 200 is not recorded. This is usually done for one day (24 hours), and the next day, the visitor captured image storage unit 151 is reset, deleted, and restarted.

By doing so, it is impossible for one person to duplicate the centralized control server 200 to record an image of a person entering and exiting the central control server 200. In other words, even if a single person records 10 fingers on each of the other persons, only one person can recognize the entrance confirmation.

The flash ROM 154 stores accessor information, for example, personal information such as a person's name and affiliation, fingerprint data, and a fingerprint image. In addition, the door open / close status data, the fingerprint authentication device 100, and central control are stored. Various data about the server 200, for example, the IP address of the fingerprint authentication device 100, the IP address of the central control server 200, the record number of the fingerprint authentication device 100, and the like are stored. In addition, the RAM 152 is a variety of data transmitted and received between the fingerprint authentication device 100 and the central control server 200 (see Fig. 2), for example, the above-mentioned access information and fingerprint authentication device 100 and the central control server ( Various data for the 200 may be temporarily stored. The central control server 200 through the operation state of the fingerprint authentication device 100 and information about the person, for example, the person, access information, for example, whether the door is opened or closed, the fingerprint authentication device 100 through It can control the information, and also can manage the information about the person.

The Ethernet communication unit 160 performs data communication through the network 300 with the central control server 200 shown in FIG. 2, and performs Ethernet TCP / IP communication with the central control server 200. The authentication apparatus 100 and the central control server 200 are each assigned an IP (INTERNET PROTOCOL) address to transmit and receive various data and accessor image file using the IP address and the record number of the fingerprint authentication apparatus 100.

Here, the Ethernet communication unit 160 and the central control server 200 transmits the IP address and the record number recorded in the fingerprint authentication device 100 to record the fingerprint authentication device 100 and then to the fingerprint authentication device 100. The various data and control information as described above are transmitted.

The door controller 170 opens or closes the door according to a control signal by the controller 110, and includes a door relay 172 and a door sensor 174.

The door relay 172 controls on / off of a motor (not shown) for operating the door according to a control signal of the controller 110 so that the door is opened or closed, and the door sensor 174 detects an entrance and exit. Do not close the door while the person passes through it.

The controller 110 generally controls the fingerprint authentication apparatus 100 for confirming entrance and exit according to an embodiment of the present invention. The controller 110 includes the fingerprint recognition unit 140, the image of the visitor captured image display unit 120, and the flash ROM ( 154, and electrically connected to the door control unit 170 (for example, by a bus method), the door is opened and closed according to the authentication result and authentication result for the door opening and closing, and data communication with the central control server 200. And control various data uploads and downloads according to data communication with the central control server 200.

In the accessor authentication process, first, when fingerprint data is output by the fingerprint recognition unit 140 for accessor authentication, the control unit 110 corresponds to the fingerprint data output by the fingerprint authentication device 100, The fingerprint data is read from the accessor information stored in the flash ROM 154, and the fingerprint data of the accessor information read from the flash ROM 154 of the memory unit 150 and the fingerprint data output from the fingerprint recognition unit 140 are read. In comparison, the door control unit 170 is controlled according to a match.

In this case, when the fingerprint data in the access information read by the flash ROM 154 of the memory unit 150 and the fingerprint data output from the fingerprint recognition unit 140 match, the door controller 170 is controlled to open the door. If different, close the door.

Hereinafter, the fingerprint image display process according to the operation of the controller 110 will be described in detail with reference to FIG. 3.

3 is a flowchart illustrating a fingerprint authentication method for access confirmation according to an embodiment of the present invention.

When the person interviews a finger on the pad of the fingerprint recognition unit 140, the fingerprint input unit 142 scans the person's fingerprint (S10), generates the person's fingerprint data (S20), the generated fingerprint data, and the flash The fingerprint information is compared with the fingerprint data stored in the ROM 154 (S30). When the fingerprint data of the two do not match, the door is closed through the door controller 170. When the fingerprint data of the two coincide, the controller 110 opens the door through the door relay 172 of the door controller 170, photographs the person through the person imaging unit 112, and captures the captured person image. Is stored in the person image capture image storage unit 151 as the year, month, date and time. * Or year, month, date and time ID.

Thereafter, the controller 110 causes the person captured image comparison unit 114 to compare the identity between the person captured images stored in the person captured image storage unit 152 (S50). Algorithms used for comparing the identity may be selected to be selected by those skilled in the art. As a result of the comparison, if there is no entrance image captured by the user, the controller 110 determines that the new entry is a new entry, and sets the entrance image to date, month, date, time, or year, date, time, ID. *, And the Ethernet communication unit 160. Through the recording to the central control server 200 connected to the network 300 through. As a result of the comparison, if there is a person image captured as determined to be the same, the controller 110 determines that the person is not a new person and does not record the person image captured by the central control server 200.

Therefore, the administrator can know whether and how many days and how many people went to work just by searching for the image file of year, month, date and time. * Or year, month, date and time ID. * Recorded in the central control server 200. The accessor image image storage unit 151 is updated daily.

In addition, the Ethernet communication unit 160 provides information about the person and the fingerprint authentication device 100 such as the personal information of the person corresponding to the fingerprint data output from the fingerprint recognition unit 140, the access information, and the door opening time. By using the network 300 to transmit to the central control server 200.
