(Specific example 1)

The system in Fig. 1 captures the characteristics of the iris 3 in the eye 2 of the person 1 and obtains data for personal identification. Hereinafter, this data is referred to as iris data. The system includes a camera 4, an iris data acquisition unit 5, and a terminal 6 for acquiring the iris data. In the figure, the camera 4 and the iris data acquisition unit 5 are separated from the terminal 6 as a separate device. However, the camera 4 and the iris data acquisition unit 5 can be incorporated as an integrated device with the terminal 6. The camera 4 captures an image of the iris 3 of the person 1 and sends an image signal of the iris 3 to the iris data acquisition unit 5. The iris data acquisition unit 5 receives the image signal of the iris 3 of the person 1 from the camera 4 The iris 3 is converted into a digital code from this image signal to generate iris data for personal identification, and the iris data is transmitted to the terminal 6. It should be noted that the iris data generation method and data configuration use well-known ones. The terminal device 6 acquires a certain amount of iris data for one person in this way, and performs the registration processing or the collation processing of the acquired iris data offline. The terminal device 6 takes the form of, for example, a personal computer / automatic transaction device. The terminal 6 includes 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. The iris data registration unit 7 includes a storage device, and registers iris data of a person who uses the system. The iris data collation processing unit 8 is composed of an interface for programs and input / output. When performing personal identification of a person who uses the system, a new iris data acquisition unit 5 is adopted. The iris data is compared with the iris data registered in the iris data registration unit 7. The collation result output unit 9 is composed of a display and a printer, takes in the collation result from the iris data collation processing unit 8, and outputs the collation result. The iris data registration control unit 10 is composed of an interface for programs and input / output. Register data and in association with each other. The iris data registration unit 7, the iris data collation processing unit 8, the collation result output unit 9, and the iris data registration control unit 10 can be separated from the terminal device 6 as a separate device. Alternatively, it can be incorporated as a device integrated with the terminal device 6.

Next, the operation of the iris data registration processing will be described with reference to FIG.

First, in step S1, the system communicates with the camera 4 shown in FIG. The iris data acquisition unit 5 acquires the iris data of the registration target person. Next, in step S2, the system incorporates the setting of the attribute data for individual identification of the registration target created by the system staff operating the keyboard or the like of the terminal device 6. The attribute data for personal identification is, for example, the name of the customer divided by the account number of the deposit if the attribute data is used for an automatic transaction device in a financial institution. The name is entered from a keyboard or the like, and the account number is transferred from a host computer or the like. Also, the attribute data for personal identification is the identification number of the researcher when it is used for an access control system in a laboratory or the like. Next, in step S3, the system creates a correspondence table by the iris data registration control unit 10. As shown in FIG. 2, the correspondence table associates personal identification attribute data 15 such as name and account number with iris data 16. By using this correspondence table, the system can obtain the name and account number of the user from the system user's list data. In step S4, the system registers the correspondence table 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 processing and an interface for input / output.

Next, the operation of the iris data collation processing will be described with reference to FIG. In the following description, the terminal device 6 is an automatic transaction device in a financial institution.

First, in step S11, when a person who desires a new transaction (hereinafter simply referred to as a user) visits the terminal device 6, the system uses the camera 4 and the iris data acquisition unit 5 to transmit the user information. Get the iris data of The method of acquiring iris data is the same as that for registration. Next, in step S12, the system uses the iris data collation processing unit 8 Then, the iris data registered in the iris data registration unit 7 is read, and the iris data acquired in step S11 is compared with the iris data read in step S12 for comparison. I do. That is, in the system, the iris data matching processing unit 8 registers the iris data which coincides with the iris data composed of the fixed amount of encoded digital data acquired in step S11. A search process is performed to determine whether or not the data is registered in the part 7. If the matching data is registered in the iris data registration part 7, the attribute data for personal identification 15 registered in association with the data is read out. . For this search processing method, the technology conventionally used in character search and other various database search processing is adopted as it is.

Next, in step S13, the system outputs the collation result by the collation result output unit 9. For example, if the iris data registration unit 7 has iris data that matches the iris data of the user, the display of the terminal device 6 indicates that "there exists iris data", The following is displayed. "If there is no matching iris data," No corresponding iris data "is displayed. In addition, the collation result is output to a host computer (not shown) connected to the terminal 6 via a communication line. In this case, in step S14, the host computer determines whether or not a transaction is possible based on the matching result. Then, when the collation result is “there is applicable iris data”, the process proceeds to step S15, and the transaction is started. If the collation result is “No applicable iris data”, the process proceeds to step S16. Then, the terminal device 6 displays, for example, "You have not registered iris data" on the display. The above system is not limited to automatic transaction equipment at financial institutions, but is installed at the entrance of a building to prevent entry and exit by outsiders. Available for management system.

The system configured as described above can have a simple configuration because the terminal processes all registration and collation of iris data.

(Specific example 2)

FIG. 4 is a block diagram showing an iris data matching system of the second embodiment.

This system also includes a camera 4, an iris data acquisition unit 5, and a terminal 6 for acquiring iris data of a person 1. Further, the terminal device 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 card 20 carried by the person 1 performs iris data registration processing. That is, the card 20 is provided with an iris data registration unit 7. This card 20 is preferably constituted by, for example, an IC card having a sufficient storage capacity for registering iris data. The card 20 is mounted on a force reader / writer 21, and various data are read and written by the terminal 6 via the card reader 21. For example, in the collation process, the terminal 6 reads the iris data from the iris data registration unit 7 of the card 20 by the iris data collation processing unit 8 of the terminal 6. After that, the terminal device 6 compares the iris data read from the card 20 with the new iris data actually obtained by the camera 4 and the iris data obtaining unit 5 and compares them. The collation result and the like are output by the collation result output unit 9 in the same manner as in 1. The other processing is the same as in the first embodiment.

This system has the following effects. That is, in this system, the iris data is registered inside the card 20. Therefore, even if the person operating the terminal 6 does not have the permission of the person in question, the iris data can be obtained. It cannot be easily referenced or modified. Therefore, this system can safely store iris data, which is important data for identity verification. In addition, this system can use the iris data registered in the card 20 not only for a specific terminal, but also for an unspecified terminal or a completely different system.

(Specific example 3)

This system improves on the system in Fig. 4 and increases the security of iris data storage.

That is, the card 20 such as an IC card carried by the user can store a program for performing iris data collation processing, registration processing, and the like. Therefore, in this specific example, the iris data collation processing unit 8, the collation result output unit 9, the iris data registration control unit 10 and the iris data registration unit 7 are stored in the card 20. It should be noted that the iris data registration section 7 itself needs to store only the iris data of the user himself, and a relatively small storage area is sufficient.

In this system, when registering the iris data, the card 20 user attaches the card 20 to the force reader / writer 21 and transfers the iris data via the terminal 6. Capture to code 20. Then, in the card 20, the iris data registration control unit 10 and the like operate to perform iris data registration processing. Also, the user of the card 20 mounts a force 20 on the card reader / writer 21 and performs a new iris via the terminal 6 at the time of the verification processing for identity verification. Import data to card 20. Then, in the card 20, the iris data collation processing section 8 and the like operate to perform collation processing, and output the collation result to the terminal 6. Other processing Is the same as that of the specific example 1.

In this system, the iris data is not output to the terminal device 6. Therefore, the confidentiality of the iris data can be guaranteed. Therefore, the security of the system for personal identification using the iris data can be enhanced.

(Specific example 4)

FIG. 6 is a block diagram showing an iris data matching system of the fourth embodiment.

In this example, the camera 4 and the iris data acquisition unit 5 are connected to the terminal 6, and the terminal 6 and the host computer 30 are connected via the communication line 25. In addition, an iris data collation processing unit 8 and a collation result output unit 9 are provided in the control unit of the terminal 6, and an iris data registration unit 7 and an iris data registration control unit 8 are provided in the host computer 30. The system configured as described above can entrust the host computer 30 with control of iris data registration and iris data storage.

In this system, the terminal 6 calls the host computer 30 at the time of the collation processing, and incorporates iris data necessary for the collation. Then, the terminal device 6 compares the iris data acquired by the camera 4 and the iris data acquisition unit 5 with the iris data acquired from the host computer 30 and collates them. When performing the iris data registration processing and the collation processing, a procedure for transferring the iris data via the communication line 25 is included. Other processes are the same as those described in the first embodiment.

In this way, iris data can be acquired by a large number of terminals and the iris data can be centrally managed by the host computer 30, so that data management becomes easy. (Specific example 5)

FIG. 7 is a block diagram showing an iris data collation system of Example 5.

In this example, a terminal 6 and a host computer 30 are connected via a communication line 25. Then, the host computer 30 is provided with an iris data registration unit 7, an iris data collation processing unit 8, a collation result output unit 9, and an iris data registration control unit 10. In this system, a terminal 6 has a function of acquiring iris data and a function of communicating with a host computer 30 via a communication line 25. The iris data registration processing and collation processing are performed by the host computer 30.

In this system, the terminal device 6 can have a simple configuration. This system is suitable, for example, when the terminal 6 must be sufficiently reduced in size and the terminal 6 cannot have various functions.

(Specific example 6)

FIG. 8 is a block diagram showing an iris data collation system of Example 6.

In this system, for example, a plurality of cameras 4, a license data acquisition unit 5 and a terminal 6 are connected to a communication line 25. That is, for example, a terminal 6 to which a plurality of cameras 4 and iris data acquisition units 5 are connected, or a plurality of terminal devices to which each of the cameras 4 and iris data acquisition units 5 are connected are arbitrary. As many as are connected to the communication line 25. The host computer 30 is provided with an iris data registration unit 7 and an iris data registration control unit 10 to register iris data in the host computer 30. In addition, the iris data collation processing is performed by a function exclusively for iris data collation connected to the host computer 30 via the communication line 25. Iris data verification computer (hereinafter simply referred to as another terminal) 6 A.

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. The iris data necessary for collation is transferred and copied from the iris data registration unit 7 of the host computer 30 to the iris data registration unit 7A in advance. That is, before the iris data collation processing, an operational file is formed here in advance. Then, when there is a request for collation at an arbitrary timing from a plurality of terminals 6, the other terminal 6A refers to the iris data registration unit 7A, performs iris data collation processing, and compares the collation result. Output by the collation result output unit 9.

This system is described below using an example of an automatic transaction device of a financial institution.

In financial institutions, the terminal 6 is in the form of an automatic transaction device. A number of such automatic transaction devices are installed in one financial institution, each of which is provided with a camera 4 and a file data acquisition unit 5. The automatic transaction apparatus is connected to the host computer 30 or another terminal 6A on-line. In such a system, registration of iris data is centrally managed by a host computer 30 at a bank head office or the like, and verification of iris data obtained by a large number of automatic transaction machines is performed by other computers. This is performed by the terminal 6A. The system configured in this way can support large-scale systems such as the online trading network of financial institutions. Further, this system is suitable for, for example, a terminal having a small size in an access control system for a building having a large number of entrances.

(Specific example 7)

The iris data registration unit 7 registers iris data with a low degree of personal identification accuracy by simplifying the amount of iris data that can reliably identify individuals. can do. Hereinafter, such a system will be described with reference to FIG. 8 as an example of a system in which a large number of terminals 6 monitor the behavior of a specific person. 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. Should be generated.

In a system in which the behavior of a specific person is monitored by a large number of terminals 6, the host computer 30 reliably identifies the specific person from the iris data registered in the iris data registration unit 7. Even if not possible, it generates file data simplified so that it is possible to identify the person as a specific person, and transfers the data to another terminal 6A. The other terminal device 6A registers the simplified iris data by the host computer 30 in the iris data registration section 7A. As a result, the amount of iris data registered in the iris data registration unit 7A of the other terminal 6A is sufficiently reduced. Then, when performing personal identification using iris data in another terminal 6A, the simplified iris data registered in the iris data registration unit 7A is used.

In such a system, the accuracy of personal identification is lower than in the case of performing personal identification using the iris data registered in the host computer 30.

Instead, in this system, the storage device provided for each of the other terminals 6A can have a small capacity, and the space for installing the storage device can be reduced. Therefore, this system can be small and low cost. Further, since the amount of data to be collated is small in this system, the configuration of the iris data acquisition unit and the like can be simplified and the collation speed can be increased. This system registers iris data that can identify the person to be monitored with certainty at one of the many terminals installed at major locations, and performs reliable identification at major locations, or By using various personal identification technologies, it is possible to accurately confirm where the monitored person is.
