Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an iris data collation system for registering and collating iris data for personal identification.

[0002]

2. Description of the Related Art For example, when performing a deposit / withdrawal transaction using an automatic transaction device in a financial institution such as a bank, individual identification is performed before the transaction is started. That is, a process of inputting a personal identification number and confirming whether or not the person is the person himself / herself is carried out in advance so as to prevent an illegal transaction using an account of another person. However, if the personal identification number or the like is known to others for some reason, there is a risk that illegal transactions will be conducted. Therefore, in this type of device, a safer method of personal identification is being researched. As a personal identification method of this kind, a method of capturing fingerprints, voiceprints, and various other characteristic points of individuals has been developed. Among them, methods using, for example, the features of the retina and iris of the eye are introduced (Japanese Patent Laid-Open Nos. 1-306984 and 1-175362).

[0003]

By the way, there are various problems to be solved in order to apply the above-mentioned conventional means for personal identification to an actual transaction device or entrance / exit management of a building. In particular, when using iris, that is, iris data for personal identification, a practical system configuration in which the iris data is registered and managed, and the iris data of a customer who has visited a transaction etc. is acquired and collated. Is required.

[0004]

The present invention adopts the following constitution in order to solve the above problems. <Structure 1> An iris data acquisition unit that receives an image of a person's iris captured by a camera and obtains iris data for personal identification, and a terminal that accepts the iris data are provided. An iris data registration unit that stores the iris data in association with personal identification attribute data, an iris data registration control unit that controls the registration process of this iris data, and new iris data acquired from the iris data acquisition unit for matching. And an iris data collation processing unit that compares and collates the iris data read from the iris data registration unit, and a collation result output unit that outputs the collation result.

<Description> The iris data is data suitable for personal identification, such as a fingerprint. If this is to be used for an automatic transaction device of a financial institution or an entrance management system of a laboratory, a system for accepting and collating the data is required. At this time, the problem is where to store the iris data registered in advance and where to perform the matching process. Here, as shown in FIG. 1, the iris data is registered in the terminal device 6 which is directly connected to the iris data acquisition unit 5 and performs various controls, and the matching process is performed in this terminal device. Therefore, this is suitable for a system for identifying a limited number of users such as an entrance management system. Personal identification attribute data refers to data such as an individual name. It should be noted that the iris data for personal identification exhibits its function with a relatively small amount of data. Therefore, even a terminal such as a personal computer can store and verify the iris data of a large number of subjects. This configuration,
That point is also taken into consideration.

The output of the collation result may be in any format, either display or print. Further, the output may be directly supplied to a device or the like that executes transaction processing by using the collation result. Since the acquisition of iris data can be performed in an extremely short time, the transaction can be started more smoothly than when entering a personal identification number using a card. In addition, there is no trouble caused by forgetting the password or wrong number, and the damage caused by card theft is also eliminated. In addition, even if you lose your card, you can withdraw your deposit without a passbook or seal.

<Structure 2> An iris data acquisition unit for receiving an image of a person's iris taken by a camera to obtain iris data for personal identification, and a terminal device for receiving the iris data are provided in this terminal device. , A card reader / writer that is set inside the card for personal identification and that stores and stores iris data in association with personal identification attribute data to the iris data registration unit that writes and reads iris data when the card is mounted. , The iris data registration control unit that controls the iris data registration process, the new iris data acquired from the iris data acquisition unit for matching, and the iris data of the card installed in the card reader / writer before starting the matching process. Iris data matching process that compares and matches the iris data read from the data registration unit If, provided with the collation result output section which outputs the verification result.

<Explanation> Iris data is important data for personal recognition. Therefore, for safety, it is preferable to store the information while preventing it from being used by others. Therefore, here, as shown in FIG. 4, the iris data is stored and registered in a card 20 such as a magnetic card or an IC card, and only the person himself holds the data. At the time of verification for identity verification, this is read out to the terminal device 6.

<Structure 3> An iris data acquisition unit for receiving an image of a person's iris taken by a camera to obtain iris data for personal identification, and a terminal device for receiving the iris data are provided in this terminal device. The card for verifying the identity, which is mounted on the card reader / writer before starting the matching process, controls the iris data registration unit that stores the iris data in association with the personal identification attribute data and the iris data registration process. Iris data registration control unit and the iris data matching process that accepts new iris data acquired from the iris data acquisition unit for matching from the terminal and compares it with the iris data read from the iris data registration unit And a collation result output unit for outputting the collation result.

<Explanation> For more strict management of the iris data, as shown in FIG. 5, while registering the iris data inside the card 20 such as an IC card owned by the person himself, the matching process is also performed for the card. Do it internally. Therefore, the registered iris data will not be taken out of the card and will not be misused by others.

<Structure 4> An iris data acquisition unit that receives an image of a person's iris taken by a camera and obtains iris data for personal identification, a terminal that receives this iris data, and a communication line to this terminal. An iris data registration unit that stores the iris data in association with the personal identification attribute data, and an iris data registration control unit that controls the iris data registration process. Is provided, and the terminal compares the new iris data acquired from the iris data acquisition unit for verification with the iris data read from the iris data registration unit of the host computer and transferred. An iris data matching processing unit and a matching result output unit that outputs this matching result are provided. .

<Explanation> In a large-scale system having a large number of terminals, it is preferable to centrally manage the iris data by a host computer. Therefore, as shown in FIG. 6, the iris data registration unit 7 and the like are provided on the host computer 30 side. In addition, the iris day collation processing unit 8 is provided on the terminal 6 side.
The reason for providing the above is to reduce the load on the host computer. Further, the iris data, which has a relatively small amount of data per case, can be easily transferred at high speed through the communication line, and the structure is utilized.

<Structure 5> An iris data acquisition section for receiving an image of a person's iris photographed by a camera and obtaining iris data for personal identification, a terminal for receiving this iris data, and a communication line for this terminal. An iris data registration unit for storing the iris data in association with the personal identification attribute data, and an iris data registration control for controlling the iris data registration process. Part, the iris data matching processing part that compares the new iris data acquired from the iris data acquisition part for matching with the iris data read from the iris data registration part, and the matching result that outputs this matching result. And a result output unit.

<Explanation> In this configuration, as shown in FIG. 7, the host computer 30 side performs everything from iris data registration to collation processing. Suitable when the host computer has sufficient processing power.

<Structure 6> An iris data acquisition unit that receives an image of a person's iris taken by a camera and obtains iris data for personal identification, a terminal that accepts this iris data, and a communication line to this terminal. An iris data registration unit that stores the iris data in association with the personal identification attribute data, and an iris data An iris data registration control unit that controls the registration process of the iris data registration unit is provided, and the iris data registration unit that registers the iris data transferred from the host computer and the iris data acquisition unit for matching are provided to the other terminals. Compare the new acquired iris data with the iris data read from the iris data registration section And iris data collation processing section for collating Te, and a verification result output unit for outputting the collation result provided.

<Explanation> In this configuration, as shown in FIG. 8, the matching process is performed by the terminal 6A which is different from the terminal 6 which acquires new iris data for matching. In the case of building entry / exit management, etc., the terminal 6 directly connected to the plurality of iris data acquisition units 5 may lack the capability of collation processing and the like. Therefore, the collation process and the like are performed by the other terminal 6A. One terminal may be connected to a plurality of iris data acquisition units 5, or a plurality of terminals 6 connected to the iris data acquisition unit 5 may be provided. The iris data is registered by the host computer 30, and the registered data is transferred in advance to another terminal 6A for collating the iris data. The iris data registered on the host computer side is used as a master file, and the iris data registered on the other terminal side is used as an operation file.

<Structure 7> The iris data registration unit of the terminal is registered with iris data with low individual identification accuracy, which is simplified iris data that can surely identify an individual.

<Explanation> For example, when the behavior of a specific person or a plurality of persons is monitored by a large number of terminals, it is necessary to register all the iris data necessary for a large number of terminals. It is not realistic in terms of installation space and cost of the storage device. This is because the terminal can be installed in any place such as a gate, a door of a building, and a passage. Therefore,
Even if the person cannot be identified, the simplified iris data that allows the person to be identified as a likely person is registered. As a result, simple management is possible even if the individual identification accuracy is low. Further, if the amount of data to be collated is small, the collation speed is also increased. Furthermore, the configuration of the iris data acquisition unit can be further simplified. To confirm that you are the person, you can register the iris data that can identify the individual surely in the one installed in the main part of many terminals, or narrow down the search range of that person. Any other appropriate means may be adopted.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to specific examples. <Specific Example 1> FIG. 1 is a block diagram showing an iris data matching system of a specific example 1. The system shown is for person 1
Data for personal identification is obtained by capturing the features of the iris 3 in the eye 2. This data is called iris data.
A camera 4, an iris data acquisition unit 5, and a terminal 6 are provided to acquire this data. The control unit of the terminal 6 is provided with an iris data registration unit 7, an iris data collation processing unit 8, a collation result output unit 9, an iris data registration control unit 10, and the like. Camera 4 is person 1 iris 3
The iris data acquisition unit 5 is a part that takes in the image as an image signal and generates iris data for personal identification from this signal. The acquisition method, data structure, and the like that are already well known are used.

The terminal device 6 is composed of, for example, a personal computer for receiving a fixed amount of iris data for one person thus obtained and performing registration processing and collation processing. The iris data registration unit 7 comprises a storage device for registering and storing iris data. The iris data collation processing unit 8 is a unit that collates the iris data acquired from the iris data acquisition unit 5 when a person comes in for a transaction or the like. The collation result output unit 9 is a part that outputs the collation result. The iris data registration control unit 10 is a part for performing processing for registering the iris data of the user on the iris data registration unit 7.

Next, a specific operation of the iris data registration process will be described with reference to FIG. First, in step S1, the camera 4 and the iris data acquisition unit 5 shown in FIG.
Iris data is acquired by. Next, in step S2, the personal identification attribute data of the person to be registered is set by operating the keyboard or the like of the terminal device 6.
This personal identification attribute data is, for example, the name of the person,
The account number of the deposit, etc. Although the name is input from the keyboard or the like, the account number is transferred from the host computer or the like. In case of laboratory access control, it will be the identification number of the researcher. Next, in step S3, a correspondence table is created. As shown on the right side of the flowchart, this correspondence table associates the personal identification attribute data 15 such as name and account number with the iris data 16. By this, when the iris data is acquired,
You can get the person's name and account number. In step S4, this is registered in the iris data registration unit 7. The iris data registration control unit 10 shown in FIG. 1 includes a program for executing such a series of registration processes and an interface for input / output.

Next, the iris data collation processing operation will be described with reference to FIG. First, in step S11, when a new person who wants to make a transaction comes, the iris data is acquired. How to get the iris data
It is exactly the same as when registering. In step S12, the registered iris data for verification is read. Then, the matching is performed. Iris data consists of a fixed amount of encoded digital data. A search process is performed to determine whether data having the same content as this data is registered in the iris data registration unit 7. As the method of this search processing, the technique conventionally used in various database search processing such as character search is directly adopted. The above processing is executed by the iris data matching processing unit 8 shown in FIG.

Next, in step S13 of FIG. 3, the collation result is output. In this example, the matching result is
An output such as "not applicable" or "applicable and the account number is as follows" is obtained. Then, this output is sent to a device that controls deposit / withdrawal transactions and the like. In this case, step S14
In step S1, it is determined whether there is a match, and if there is a match, the transaction for that account is started (step S1).
5). If there is no corresponding item, the process proceeds to step S16, for example, "You have not registered iris data".
Is displayed. The above system can be used not only for transactions such as deposit and withdrawal, but also for deposit and withdrawal management for preventing entry by outsiders by being installed at the entrance of a building, for example. In this case, the terminal system handles the registration and verification of iris data at all, resulting in a simple system.

<Second Embodiment> FIG. 4 shows an iris data collation system of the second embodiment. This system is also for person 1
The camera 4, the iris data acquisition unit 5, and the terminal 6 are provided to acquire the iris data of the. Further, the terminal 6 is provided with an iris data collation processing unit 8, a collation result output unit 9, an iris data registration control unit 10, and the like. In this specific example, the iris data is registered on the side of the card 20 carried by the person 1. That is, the card 20 is provided with the iris data registration unit 7. The card 20 is preferably composed of, for example, an IC card having a sufficient capacity for recording iris data. The card 20 is attached to the card reader / writer 21, and the terminal 6 reads and writes data.

The iris data registration procedure and collation processing of this system are the same as those of the first embodiment, but since the iris data is registered inside the card 20, even the terminal 6
It is not easy for the staff who operates the iris data to refer to or modify the iris data without the permission of the person. Therefore, the iris data, which is important data for identity verification, is safely stored. Further, there is an effect that the registered iris data can be used not only in the terminal device but also in an unspecified terminal device or a completely different system. In the collation process, the iris data is read from the iris data registration unit 7 by the iris data collation processing unit 8 via the card reader / writer 21 and compared with the actually acquired new iris data for reference. . The output of the collation result after that is the same as that described in the first specific example.

<Example 3> FIG. 5 shows an iris data collation system of Example 3. This system is a further improvement of the system of FIG. 4 to enhance the safety of storing iris data. That is, the card 20 such as an IC card can store a program for performing iris data matching processing, registration processing, and the like. Therefore, in this specific example, the iris data collation processing unit 8, the collation result output unit 9, and the iris data registration control unit 1 are provided in the card 20.
0 and the iris data registration unit 7 are stored. The card 20 is always owned by the person. When registering the iris data, the card 20 is attached to the card reader / writer 21, the iris data is loaded into the card 20 through the terminal device 6, and the registration process is performed. Further, in the processing for confirming the identity, new iris data is input to the card 20 through the terminal device 6, and then the iris data matching processing unit 8 and the like operate to perform the matching processing. The verification result is returned to the terminal device 6. It should be noted that the iris data registration unit 7 itself needs to store only the iris data of its own, and a storage area having a relatively small capacity is sufficient. Note that the other registration operations and collation processing operations are the same as those in the first specific example.

<Fourth Embodiment> FIG. 6 shows an iris data collation system of a fourth embodiment. In this example, the camera 6 and the iris data acquisition unit 5 are connected to the terminal device 6, and the control unit thereof is provided with the iris data collation processing unit 8 and the collation result output unit 9. Meanwhile, the terminal 6 is connected to the communication line 25
The iris data registration unit 7 and the iris data registration control unit 10 are provided on the host computer 30 side. That is, in this system, the host computer 30 entrusts iris data registration control and iris data registration storage. Then, in the matching process, the host computer 30 is called to receive the required iris data on the terminal 6 side,
Perform the actual matching process.

In this way, when the iris data for registration is acquired by a large number of terminals and the host computer 30 centrally manages the iris data, the data management becomes easy. It should be noted that a procedure for transferring the iris data via the communication line 25 is included in the registration and collation processing of the iris data. Others are the same as those described in the first specific example.

<Fifth Embodiment> FIG. 7 shows an iris data collation system of a fifth embodiment. In this example, the terminal 6 is connected to the host computer 30 via the communication line 25, and the iris data registration unit 7, the iris data matching processing unit 8, the matching result output unit 9, and the iris data registration are provided on the host computer 30 side. A control unit 10 is provided. For example, when the system is adopted in a place where the terminal needs to be sufficiently reduced, it is difficult to request various functions from the terminal. Therefore, the terminal has only the function of acquiring the iris data and controlling the communication with the host computer 30 through the communication line 25, and the host computer 30 performs the iris data registration / verification processing.

<Sixth Embodiment> FIG. 8 shows an iris data collation system of a sixth embodiment. In this system, for example, a plurality of cameras 4, an iris data acquisition unit 5, and a terminal 6 are connected to a communication line 25. That is, for example,
An arbitrary number of terminals 6 connected with a plurality of cameras 4 and iris data acquisition units 5 or a plurality of terminals connected with one camera 4 and one iris data acquisition unit 5 are connected to the communication line 25. An iris data registration unit 7 and an iris data registration control unit 10 are provided on the host computer 30 side. Register the iris data here. Further, the collation of the iris data is performed by another terminal 6A provided separately from the collation.

The other terminal 6A is connected to the communication line 25. The other terminal 6A is provided with an iris data registration unit 7A, an iris data collation processing unit 8, and a collation result output unit 9. In the iris data registration section 7A,
The iris data registration unit 7 of the host computer 30 in advance
The necessary iris data is transferred from and copied. That is, an operational file is previously formed here before the iris data matching process. And a plurality of terminals 6
When there is a matching request from the user, the other terminal 6A refers to the iris data registration unit 7A and executes the iris data matching process. Then, the result is output by the matching result output unit 9.

Such a system is practical, for example, when the terminal itself has a small size due to entrance / exit management of a building having a large number of entrances / exits. For example, in FIG. 8, in the case of a system in which a large number of terminals 6 monitor the behavior of a specific person, first, the host computer 30
Even if the iris data registered in the iris data registration unit 7 is not surely determined to be that person,
The content should be simplified so that you can understand what it looks like. As a result, the amount of data is sufficiently reduced. This simplified iris data is transferred to another terminal 6A and registered in the iris data registration unit 7A. That is, the iris data matching process using the other terminal 6A may have a lower individual identification accuracy than the case of using the iris data registered in the host computer 30. As a result, the storage device of the other terminal 6A and other circuit configurations are simplified, and the size and cost can be reduced.

In order to simplify the iris data,
A part of the original iris data may be cut out, sampled according to an appropriate rule, or the iris data acquisition process itself may be simplified and newly generated. Further, for example, a terminal for acquiring iris data is provided in each automatic transaction device of a bank, and one other terminal 6A is provided in each bank. In this way, the collation processing of the iris data acquired by a large number of automatic transaction devices is performed by the other terminal 6A. The registration of the iris data is unified and managed by the host computer 30 in the head office of the bank. With such a configuration, a large-scale system can be supported.
