Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for recognizing whether or not an individual is an individual.

[0002]

2. Description of the Related Art In an automatic cash transaction system and an entry / exit management system, in order to guarantee the security of transactions and the reliability of management,
Individuals need to be identified. Since iris patterns are different for each person, personal recognition devices that identify individuals using iris data are being widely adopted in those systems.

[0003]

However, the conventional personal recognition device has various problems as described below. (1) Even when it is necessary to perform personal recognition for a plurality of persons, each person is individually recognized. As a result, the individual recognition is completed because each person performs the overlapping procedure independently, or the personal recognition of a certain person (for example, a person with fine eyes or a person who has difficulty obtaining good iris data) is delayed. It took a lot of time to do so.

(2) Even if entry / exit is managed based on personal recognition, for example, a third party other than a person who can enter / exit normally, such as an employee or a person involved, is mistaken for entry / exit of an employee or person involved. It was difficult to avoid entering and leaving the room.

[0005] (3) Although cash transactions are permitted based on personal recognition, even those who intend to trade against their own intentions, such as threats, have to permit the transaction as usual. The lack of a transaction could not rescue traders from such acts.

[0006]

In order to solve the above-mentioned problems, in the personal recognition apparatus of the present invention for performing personal recognition based on an image of an eye of a distinguished person, a photographing unit includes The imaging unit is used for inputting the number of persons for continuous imaging, and the control unit causes the imaging unit to continuously photograph the eyes of the identified persons of the input number. This allows
Since it is possible to avoid duplicate procedures, it is possible to shorten the time until the individual authentication of all the members is completed.

[0007] In another aspect of the present invention, the iris data obtaining section obtains iris data representing the iris of the identified person,
The iris data storage unit stores iris data representing the iris of the identified person in advance, and the iris comparison unit compares the acquired iris data with the stored iris data so that the two iris data match. The weight measuring unit measures the weight of the identified person, the weight storage unit stores the weight of the identified person in advance, and the weight comparing unit determines the measured weight of the identified person. By comparing the weight of the discriminator stored with, it is determined whether or not both weights match, the determination unit, the iris comparison unit determines that both iris data match,
And when the weight comparison unit determines that both weights match,
The identified person is determined to be the person. As a result, it is possible to determine whether there is a person other than the person,
It is possible to prevent a situation in which a third party takes advantage of the person to enter and exit the room.

In another aspect of the personal recognition apparatus of the present invention, the iris data obtaining section obtains iris data representing the iris of the identified person, and the iris data storage section previously stores iris data representing the iris of the identified person. Then, the iris comparison unit compares the acquired iris data of the identified person with the stored iris data of the identified person to determine whether the two iris data match, and determines the pulse measurement. The unit measures the pulse of the identified person, the pulse storage unit stores the pulse of the identified person in advance, and the pulse comparing unit compares the acquired and measured pulse of the identified person with the stored identified person. By comparing the two pulses, it is determined whether the two pulses match, the determination unit, the iris comparison unit determined that both iris data match, and the weight comparison unit determined that both weights match Sometimes, it is determined that the identified person is the person himself. Thereby, since the trader's own intention can be confirmed, it is possible to avoid a situation where the trader conducts a trade against his / her own intention.

Step S200: When the identified person starts using the entry / exit management system, the photographing unit 30 photographs the eye of the identified person and outputs an image of the eye. When given an image of the eye, the processing unit 31 generates iris data from the image. Step S210: The iris matching section 33 stores the iris data of the identified person generated by the processing section 31 and the iris storage section 3
By comparing the iris data of the identified person as the permitted person to enter / leave stored in 2 with the iris data, it is determined whether the identified person to enter / leave the room is the person himself or herself. Step S
220: If it is determined that the person is the person, the weight measuring unit 34
Measures the weight of an object in a predetermined range.

Step S230: The weight collating unit 36 collates the weight of the object measured by the weight measuring unit 34 with the weight of the identified person stored in the weight storage unit 35 in advance. Judge whether there is a third party around the person. Step S240: When it is determined that there is no third party because the difference between the two weights is small, the weight collation unit 36 notifies the permission unit 37 of that fact. Upon receiving this notification, the permission unit 37
The control unit 41 in the entry / exit management device 4 is instructed to open the door unit 40. In accordance with this instruction, the control unit 41
