Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a personal identification device which is used as a room entry / exit management device for managing entry / exit to and from an important facility and which carries out personal authentication using characteristic information of an individual's finger.

[0002]

2. Description of the Related Art In recent years, for the purpose of maintaining confidentiality in a building or a room, a personal authentication device is often installed which manages only a specific individual to enter or leave the building or the room. ..

For example, as a personal authentication device for authenticating a specific individual, a method is known in which characteristic information of the entire finger is used without using a fingerprint. This is done, for example, by placing a finger on the prism and illuminating it with a light source.
The addition information obtained by adding the image information in the direction orthogonal to the finger from the image information of the finger obtained by photographing the abdominal surface image of the finger with the television camera and A / D converting the output is used as the characteristic information of the finger. To do.

In the matching process, the registered characteristic information registered in advance and the matched characteristic information input as described above for matching are aligned, the difference S between the two at that time is obtained, and this is calculated. It is called the dissimilarity and is used as the matching result. The value of the dissimilarity S takes a smaller value as the two pieces of feature information are more similar, and becomes “0” when they completely match. The judgment process is
Using an appropriate threshold value T, the person and the other person are judged as follows. When S ≦ T: determined to be the person S> T: determined to be another person Next, the entry / exit management using such a personal authentication device will be described.

FIG. 3 shows a conventional personal identification device, which includes a control unit 21 for overall control, a numeric keypad 22 for inputting a personal identification number of a person entering the room, and characteristic information of a finger of a person entering the room. It is configured by a finger image input unit 23, a storage device 24 that stores a personal identification number registered in advance and characteristic information of an individual's finger corresponding thereto, and an unlock controller 26 that unlocks the door 25 under the control of the control unit 21. Has been done.

Next, the operation will be described. First, a user who wants to enter the room inputs his / her own personal identification number using the ten-key pad 22, and also inputs the characteristic information of his / her finger from the finger image input section 23. The input personal identification number and the characteristic information of the finger are sent to the control unit 21. The personal identification number at this time is the first key for opening the door, and the characteristic information of the finger is the second key for opening the door. The control unit 21 reads the characteristic information of the finger corresponding to the personal identification number input from the ten key 22 from the storage device 24.

The control unit 21 collates the characteristic information of the finger read from the storage device 24 with the characteristic information of the finger from the finger image input unit 23, and determines whether or not the characteristic information matches (whether or not the person is the same). Or) is determined. When both feature information match, the control unit 21 outputs an unlock signal to the unlock controller 26,
The door 25 is unlocked by the unlock controller 26. If the two pieces of characteristic information do not match, the control unit 21 does not output the unlocking signal, and therefore the unlocking controller 26 does not unlock the door 25.

Further, for example, in the case of a person who does not normally enter the room and has the authority to enter the room (for example, an executive), or when inspecting an important customer, that person must also have a personal identification number and a finger beforehand. The characteristic information is registered, and the room is entered by the method described above.

[0009]

As described above, the conventional method of inputting a personal identification number requires time for inputting the personal identification number with the ten-key pad, and if the personal identification number is forgotten, access is possible. There is inconvenience such as disappearance. Also,
In the case where the personal identification number itself is known to a third party, there is a problem that the first key for entering and leaving the room is lost, and the personal identification number can be passed through trial and error.
In addition, whenever an executive or an important customer is inspected,
There was an inconvenience that the person to be inspected had to register the personal identification number and the characteristic information of the finger.

Therefore, an object of the present invention is to provide a personal identification device which can simplify an input operation, prevent unauthorized access, and eliminate inconvenience.
