Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ID verification for judging whether or not a holder who has an ID such as a driver's license has forged the ID, and verifies the ID. Regarding the system.

[0002]

2. Description of the Related Art For example, when a police officer asks a driver of a vehicle to show his driver's license to control a traffic violation or a crime, the police officer should compare the photograph of the driver's license with the person himself. Check if the driver's license belongs to him or her by asking the driver what to enter. However, it is not easy to confirm the fact that the driver's license is forged with this alone. Therefore, if there is any doubt, the license number is notified to the headquarters by radio telephone and the corresponding data registered in the host computer is searched. The search results are notified to the police officers at the site and various interrogations are conducted. In addition to this, there is also a case where a driver's fingerprint or the like is collected to introduce a career.

[0003]

The conventional verification system for a driver's license as described above has the following problems to be solved. In the conventional system, since the person intervenes in the information transmission, it is not easy to confirm or introduce the information described in the driver's license in real time. That is, the inquiry takes a certain amount of time, and it is not easy to speed up the inquiry. Further, it is not always satisfactory to confirm whether or not the person is a person, because the method such as fingerprint collation requires more processing time and the collation accuracy depends on the fingerprint sampling technique.

On the other hand, as a method for confirming the person,
There is a method of capturing the image of the eye, recognizing the iris pattern, and comparing this. Further, it is superior to the recognition by the retinal pattern in that the pattern can be acquired without the eyes approaching the camera. This iris pattern can be acquired automatically by using a camera or the like, and it has a feature that each person can be distinguished with high accuracy. Such a technique is described in, for example, Japanese Patent Publication No. 5-84166. It is an object of the present invention to utilize the personal identification using such iris data to inquire the contents of an identification card such as a driver's license.

[0005]

The present invention employs the following structure to solve the above problems. <Structure 1> A camera for photographing the holder of the identification card, an iris pattern acquisition unit for acquiring the iris pattern of the holder from the photographed image of the holder, and transmitting the iris pattern to the host computer. The iris data file stored on the host computer side is searched for the same iris pattern to identify the above holder, and the host inquiry section that receives the information on the holder's identification card and this identification card And a display unit for displaying the items described in.

<Explanation> An identification card is for proving the identity of the holder to a third party, such as a driver's license, a passport, or a passport. The iris pattern is unique to the holder and is data obtained by processing the image of the pupil portion that can identify the holder. This data may include or include only the iris pattern. In the iris data file, the iris patterns of a large number of subjects and the items to be recorded on the identification card are stored in association with each other. Therefore, if you search for data that matches the iris pattern, you can return the information on the person's identification card.

The display unit may have any configuration as long as it can display the items described in the identification card, and may be a printer, a display, or the like. Items displayed on this display,
By collating with the presented identification card, it can be determined whether the holder owns the authentic identification card of the person in question, or possesses another person's article or a forged article. If the same iris pattern does not exist in the iris data file, the fact is notified to the host inquiry unit.

<Structure 2> In Structure 1, the identification card is a driver's license, the camera is a handy camera, and the acquired iris pattern is transmitted to the host computer by wireless communication.

<Explanation> In many cases, police officers ask the driver to show his driver's license outdoors. Therefore, it is preferable that the camera is a handy type that a police officer can carry around, and the iris pattern is transmitted to the host computer by wireless communication. The process of acquiring the iris pattern from the image taken by the camera may be performed by a processing circuit provided inside the camera, or a control terminal that executes the iris pattern acquisition process and the communication process with the host computer inside the patrol car. May be provided. In this case, it is preferable that wireless communication be performed both between the handy camera and the control terminal and between the control terminal and the host computer.

<Structure 3> A camera for photographing the holder of the ID card, an iris pattern acquisition unit for acquiring the iris pattern of the holder from the photographed image of the holder, and the information recorded in the ID card. The iris pattern obtained by the iris pattern acquisition unit and the certificate reading unit that reads the obtained iris pattern are compared with the iris pattern read by the certificate reading unit to determine whether the two match. The determination unit and the display unit that displays the determination result of the determination unit are provided.

<Explanation> When the iris patterns of a very large number of subjects such as drivers' licenses and passport holders are registered in the host computer in advance, the amount of data becomes enormous. Therefore, the process of searching for a specific iris pattern from among them is not easy and takes time. Therefore,
Record the iris pattern on the ID card by magnetic recording. This makes it possible to quickly and easily determine whether the holder of the ID card is the person who is the person who listed the ID card or another person. Moreover, communication processing with the host computer is unnecessary, the determination speed is high, and the equipment can be downsized.

<Structure 4> In Structure 1, the certificate reading unit for reading the iris pattern recorded on the identification card, the iris pattern acquired by the iris pattern acquiring unit, and the certificate reading unit for reading the iris pattern. The iris pattern is compared with a determination unit that determines whether the two match, and when the two match as a result of the comparison, the search information read by the certificate reading unit is transmitted to the host computer. , Using this search information, the same iris pattern in the iris data file stored on the host computer side is searched to identify the above-mentioned holder, and the host inquiry to receive the items described in the holder's ID card And a display unit that displays the determination result of the determination unit together with the items to be written on the identification card.

<Explanation> By providing the functions of the configuration 1 and the configuration 2 together, the reliability of verification of the holder of the identification card is improved. In addition to the iris pattern, the ID card also contains information for identifying the holder of the iris pattern, such as a key useful for searching the iris pattern data. It can be read by the department and sent to the host computer to speed up the search process. The search information is information corresponding to such a key.

[0014]

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 schematic view of an identification certificate matching system of the present invention. The present invention provides a system for inquiring about the fact that, when a holder of an ID card presents the ID card, he / she has reprinted a photo or tampered with the described items. Therefore, it can be applied to various identification cards such as a driver's license, passport, and pass certificate. In the following specific example, an example of a driver's license will be described.

First, in FIG. 1, a camera 3 for photographing the driver 1 is prepared. As the camera 3, CC
D cameras and video cameras are suitable. Then, the image of the driver 1 taken by the camera 3 is sent to the terminal device 4 and processed. The terminal device 4 includes an iris pattern acquisition unit 5, a host inquiry unit 6, and a display unit 7.
Etc. are provided. The iris pattern acquisition unit 5 uses the conventional iris pattern acquisition technique described above,
The image of the eye portion is cut out from the image of the driver 1, and the characteristic pattern of the iris portion unique to the person is extracted. The host inquiry unit 6 is a unit that transmits the iris pattern 11 from the terminal device 4 to the host computer 10 and performs a process of requesting the inquiry. The display unit 7 is provided with a display, a printer and the like for displaying the result of the inquiry made by the host computer 10.

The host computer 10 is provided with a storage unit 12, in which, for example, an iris data file 13 of drivers nationwide is stored. Host computer 1
0 receives the transfer of the iris pattern 11 and searches the iris data file 13 to obtain data in which the iris pattern matches. In this way, the information 14 of the driver's license of the driver 1 is acquired and transmitted to the terminal device 4. The items displayed on the display unit 7 are compared with the contents of the driver's license 2 shown in the figure. The system of the present invention has a schematic configuration as described above, and specifically operates as follows.

FIG. 2 shows an operation flowchart of the system of the present invention. First, in step S1, at least the face portion of the driver 1 shown in FIG. 1 is photographed.
The image is sent to the terminal device 4. The iris pattern acquisition unit 5 cuts out the image of the eyes from the image of the driver's face and obtains its image data. This image data is feature-extracted by the method described in Japanese Patent Publication No. 5-84166 described above to obtain iris pattern data (step S2). This iris pattern is transmitted from the terminal device 4 to the host computer 10 by wireless communication or the like (step S3).

The host computer 10 is installed at the police headquarters, the driver's license issuing center, or the like, and the iris data file 13 is searched there (step S4). The iris data file 13 is
Iris pattern 11 and various items to be written on driver's license 14
It is a data file in which, etc. are stored in association with each other. The host computer 10 searches for a driver having the same iris pattern from such a file, and takes out the information described in the license corresponding to the driver (step S5). This result is transmitted from the host computer 10 to the terminal device 4 (step S6). In some cases, the iris data file 13 does not store the corresponding iris data and the corresponding driver license entry. In this case, since the person is an unlicensed person, the fact is also notified to the terminal device as a result of the search. Then, in the terminal device 4, the information 14 described in the received driver's license is displayed on the display unit 7
Display in a suitable layout. This layout is preferably the same as the order in which the driver's license 2 is written, for example. This is because matching is easy.

After that, the police officer checks the driver's license 2 presented by the driver 1 and the contents displayed on the display unit 7, and if all match, the driver's license is confirmed to be his own.
In other cases, take appropriate measures because there is a suspicion of forgery. In addition, when a police officer temporarily stops the vehicle for various crackdowns and requests the presentation of a driver's license, the police officer is preferably as light as possible. Therefore, it is preferable to use so-called wireless rather than connecting the camera 3 and the terminal device 4 shown in FIG. 1 with a cable.

FIG. 3 shows an explanatory diagram of a communication method with the host in such a case. In this example, the police officer 21 is moved by the patrol car 20. And police officer 21
Owns a camera 3. In addition, the driver 1 of the vehicle 22
Is taken by this camera 3. An antenna 24 is attached to the camera 3. On the other hand, the patrol car 20 is also provided with an antenna 25. The antenna 26 is also attached to the host computer 10.

In this state, the police officer 21 makes the driver 1
When you take a picture of the
Is transmitted to the receiver of the patrol car 20.
The data received by the antenna 25 is the patrol car 20.
The iris data is acquired by processing by a terminal device (not shown) installed inside the. Then, this is wirelessly transferred from the antenna 25 to the antenna 26 of the host computer 10. The patrol car 20
The terminal device housed inside the terminal may be a terminal device configured as shown in FIG. The host computer 10 wirelessly notifies the patrol car 20 of the search result again. Therefore, the items to be written on the driver's license are displayed inside the patrol car 20. After that, for example, the contents can be transmitted by a transceiver or the like between the police officer 21 on the spot and the police officer who is waiting inside the patrol car 20, so that the license can be verified.

As will be described later, if the camera 3 is equipped with a display or the like for displaying license information, the police officer 21 looks at the display and compares it with the license presented by the driver 1. Can be matched.
If the camera 3 itself has an iris data acquisition function, a method of directly transmitting and transferring iris data from the antenna 24 of the camera 3 to the host computer 10 is also possible.

FIG. 4 shows a schematic diagram of the second embodiment of the system of the present invention. In the above example, the iris data is sent to the host computer and the iris data file search processing is performed. However, the driver's license,
When the data of passports and other data of an extremely large number of subjects is stored in a database, the search process is not easy, and a highly complex system for high-speed search is required.

On the other hand, normally, in this type of field, the operation of the vehicle is temporarily stopped and the driver's license is inquired. Therefore, it is necessary to respond as promptly as possible. Therefore, in this specific example, the iris data of the license holder is recorded in the driver's license. The driver's license 2 shown in FIG. 4 is provided with a magnetic stripe 28 similar to a cash card of a bank or the like. The iris pattern 29 and information such as the license number 30 are stored here. It should be noted that as much information as possible is preferably stored here, for example all the driver's license information is conveniently stored on this magnetic stripe 28.

In order to read the information written on the magnetic stripe 28 of the driver's license 2, the camera 3 is provided with a card reader 34, and a certificate reading section 35 for processing the signal obtained here. Is provided.
Further, the camera 3 illuminates the driver with the illumination lamp 33,
The image is acquired using the lens 38. The irradiation lamp 33 is preferably a lamp that emits infrared light. This is because many Japanese eyes have dark colors such as black and brown, and infrared rays are preferable for photographing the features of the eyes. In addition to this, the camera 3 has an iris pattern acquisition unit 37.
And a determination unit 36 that compares the iris pattern read by the certificate reading unit 35 and determines the result. Further, a display unit 31 and an indicator lamp 32 are provided to display the determination result.

In this specific example, the magnetic stripe 2 is displayed on the display unit 31 as a matter described in the driver's license 2.
The information recorded in 8 is displayed. In addition to this, the result of comparing the iris patterns in the determination unit 36 is also displayed. The indicator lamp 32 is specially prepared in order to easily convey such a result to a person who operates it, that is, a police officer. For example, when the iris pattern matches the iris pattern recorded on the magnetic stripe 28 of the driver's license 2, the blue indicator lamp 32 lights up. When the iris pattern cannot be correctly acquired and the determination is difficult, the yellow indicator lamp 32 is turned on. Further, if the iris data is correctly acquired, but the iris pattern 29 recorded on the driver's license 2 does not clearly match, the red indicator lamp 32 is turned on. In this way,
The judgment result is configured to be easily recognized even in a dark place such as at night.

FIG. 5 is an operation flowchart of the second specific example. First, the driver is photographed in step S1 and the iris pattern is acquired in step S2. This processing is exactly the same as that described in the first specific example. Then, in step S3, the magnetic stripe of the driver's license is read. The police officer mounts the driver's license 2 received from the driver on the card reader 34 of the camera 3 and reads the data from the magnetic stripe 28. Next, in step S4, the determination unit 36 compares the iris pattern captured by the camera 3 with the iris pattern 29 stored in the magnetic stripe 28. Then, in step S5, it is determined whether or not they match. If they match, step S6
In the case of displaying the license information, compare it with the contents of the license, and if there is no problem, the inquiry ends. On the other hand, if the iris patterns do not match in step S5, the process proceeds to step S8, and an inquiry to the host computer is made by the same method as the method described above with reference to FIGS.

In this case, it is advisable to transmit the iris pattern actually acquired and the iris pattern read from the driver's license and search the iris data file using both. This makes it possible to refer to the content of the iris pattern based on the recorded data of the driver's license when the iris pattern cannot be accurately acquired.

When the driver's license is recorded with the iris pattern, the driver's license description items, etc., and is collated with the iris pattern, the reliability of the driver's license against falsification is not necessarily high. Therefore, there is a method in which the host computer side inquires about the driver's license information. In this case, in order to reduce the burden of searching a large amount of iris data files on the host computer side, at least a key for searching the iris data files is recorded in the driver's license. This becomes the license number 30 shown in FIG. 4, for example. An example using such a key will be described below.

FIG. 6 is an operation flowchart of the third specific example. First, in step S1, the magnetic stripe of the driver's license is read, and in step S2, the iris pattern is acquired and collation determination is performed. This is the same as the processing from step S1 to step S4 which has already been described with reference to FIG. Next, in step S3, the search information is transmitted to the host. That is, the search information such as the license number read from the license is sent to the host computer to request the search of the iris data file. In step S4, the host searches the iris data file and notifies the terminal device of the result. This process itself is exactly the same as the operation of steps S4 to S6 described with reference to FIG. Finally, in step S5, the iris pattern matching determination result and the driver's license entry information are displayed on the display unit of the terminal device. The determination of the iris pattern is performed based on the data recorded in the driver's license, and the driver's license entry information is the content transferred from the host computer. As a result, the driver's identity is verified and the information on the driver's license is checked.

In addition to this, for example, a search key is stored in the driver's license, the search key is transferred to the host computer, and the iris data is obtained by searching the iris data file. You may make it collate with the iris data acquired by photographing the driver on the spot. The iris pattern does not change throughout life, and unlike facial photographs, once registered, it is not necessary to update it. Therefore, it is said that it is possible to identify the person with high accuracy. Therefore, the driver's license only needs to include the minimum necessary items for such inquiry. Further, unlike the identification method using a signature, a fingerprint, a voiceprint, etc., the data can be easily obtained without the driver having to do anything, and there is an effect that the convenience and certainty are high. Further, since the iris pattern can be registered with data having a much smaller capacity than data such as a fingerprint, the capacity of the data file itself can be reduced.
