Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for identifying a person, for example, in a case where a person is used in a bank, a government office, or the like.

[0002]

2. Description of the Related Art Conventionally, for example, when confirming the identity of a person at a bank, a government office, or the like, a driver's license, a health insurance card, or the like is presented, or a seal or the like is used. However, it is inconvenient to carry such a certificate or a seal as described above, and the confirmation work is troublesome, and the confirmation is not always possible.

[0005] Therefore, a fingerprint collation apparatus has been proposed in which a user's fingerprint is registered in advance and the identity of the user is determined by collating the fingerprint with the visitor's fingerprint.

[0004]

However, in the conventional fingerprint collation device, fingerprint data is registered in advance in a memory inside the fingerprint collation device or a memory of a computer or the like connected to the fingerprint collation device, and the fingerprint data is registered in advance at the time of fingerprint collation. The fingerprint data registered has been compared with the fingerprint data from the fingerprint verification device to perform verification. Therefore, there is a problem that fingerprint data to be registered and stored increases as the number of users increases, and the labor and time required for collation increase accordingly.

[0005] The above-mentioned fingerprint collation devices are usually installed at a plurality of locations. In such a case, it is very complicated and troublesome to newly register or delete fingerprint data for each fingerprint collation device. Therefore, it is conceivable to perform centralized management at one place. However, there has been a problem that the managed device and each fingerprint collation device must be connected online.

The present invention, which has been proposed in view of the above problems, provides an identification method and apparatus that can be easily managed and that can easily and quickly identify whether or not the user is the identity. With the goal.

[0007]

In order to achieve the above object, a method and apparatus for identifying an individual according to the present invention have the following arrangement.

That is, in the personal identification method according to the present invention, the fingerprint data of the individual is recorded on the card in advance, the fingerprint of the person who brought the card is read by the fingerprint reading means, and the fingerprint read by the fingerprint reading means is read. It is characterized in that the data and the fingerprint data recorded on the card are collated to determine whether or not the user is the principal.

The personal identification device according to the present invention comprises: card data reading means for reading personal fingerprint data recorded on a card in advance; fingerprint data reading means for reading a fingerprint of a person who carries the card; and fingerprint data reading means. The fingerprint data read by the card data reading means is compared with the fingerprint data read by the card data reading means to determine whether or not the fingerprint data matches each other.

[0010]

As described above, the fingerprint data of the principal is recorded on the card in advance, and the fingerprint data recorded on the card is compared with the fingerprint data of the person who brought the card to determine whether or not the principal is the principal. This eliminates the need to register and store fingerprint data in each fingerprint matching device as in the related art, thus making it possible to manage fingerprint data and simplify the device configuration.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A personal identification method and apparatus according to the present invention will be specifically described below based on the embodiment shown in the drawings.

FIG. 1 is a schematic block diagram showing an example of a card issuing machine for recording and issuing fingerprint data on a card. The card issuing machine shown in FIG.
And card data writing means 2 and control means 3.

The fingerprint data reading means 1 puts a finger on a reading part (not shown) to convert the characteristics of the fingerprint of the finger into data, and reads the data. The card data writing means 2 reads the fingerprint data with the fingerprint data reading means 1. Write fingerprint data to the card. The control means 3 transfers the fingerprint data from the fingerprint data reading means 1 to the card data writing means 2 and controls the two means 1 and 2.

FIG. 2 shows an embodiment of the personal identification apparatus, which comprises a card data reading means 4, a fingerprint data reading means 5, a fingerprint collating means 6, and a control means 7.

The card data reading means 4 reads the fingerprint data written on the card by the card data writing means 2, and the fingerprint data reading means 5 converts the characteristics of the fingerprint into data as in the case of the fingerprint data reading means 1. read. Further, the fingerprint collating means 6 collates the fingerprint data of the card read by the card data reading means 4 with the fingerprint data read by the fingerprint data reading means 5 to determine whether or not they match. Further, the control means 7 transfers the fingerprint data from the card data reading means 4 and the fingerprint data reading means 5 to the fingerprint collating means 6, controls the respective means 4 to 6, and the like. As the control means 3 and 7, for example, an existing personal computer (hereinafter, referred to as a personal computer) can be used.

As a card for recording fingerprint data, for example, an IC card, a magnetic card, or a fingerprint data
A card or the like printed as a dimension code can be used. In particular, when a card on which fingerprint data is printed as a two-dimensional code is used, an existing printer or the like can be used as the card data writing means 2, so that a card on which fingerprint data is recorded can be created simply and at low cost. . In addition, since the existing fingerprint reader can be used almost as it is as the card data reader 4, the card data reader can be obtained only by adding the card (two-dimensional code) reader to the fingerprint reader, and it is very inexpensive. There is an advantage that it can be manufactured.

When a card on which fingerprint data is recorded is issued by the card issuing machine of FIG. 1 constructed as described above, the fingerprint data is read by the fingerprint data reading means 1 and the fingerprint data is written into the card data writing means. 2 to be written on the card and issued. When a two-dimensional code or the like is used, two-dimensional data is printed on a card using a printer or the like as the card data writing means 2.

The above fingerprint data can be stored in a memory (hard disk) of the control means (personal computer) 3 as required. By doing so, for example, when re-issuing a card, it is possible to issue the card without re-reading the fingerprint data.

Next, in order to determine whether the person who brought the card issued as described above is the person, the fingerprint data written on the card by the card data reading means 4 in FIG. At the same time, the fingerprint is read by placing the finger of the person who brought the card on a reading section (not shown) of the fingerprint data reading means 5. The fingerprint and the fingerprint data of the card are collated by the fingerprint collation means 6 to determine whether they match. And if they match,
For example, a coincidence signal is output for a certain period of time, or displayed on a display device or the like which is omitted in the figure. As a result, the identity of the person can be confirmed.

In the above embodiment, the card issuing machine (FIG. 1) and the personal identification device (FIG. 2) are separately configured. However, both are integrated, that is, the personal identification device having a card issuing function is also provided. It can also be configured. FIG. 3 shows an example of such a configuration, in which the personal identification device of FIG. 2 is provided with the card data writing means 2 of FIG. In the present embodiment, the fingerprint data reading means 5 performs both reading of fingerprint data for issuing a card and reading of fingerprint data for collation. The fingerprint data read by the means 5 is sent to the card data writing means 2 and a card is issued, and at the time of verification, the fingerprint data read by the fingerprint data reading means 5 is sent to the fingerprint verification means 6 and the card data is read. This is a configuration for collating with the fingerprint data of the card read by the reading means 4.

The card on which the fingerprint data is recorded may record not only the fingerprint data but also an expiration date, a limit on the number of times of use, a security level, a device number, a personal ID code, and the like. By doing so, it becomes easy to manage fingerprint collation and the like, and it is possible to extend the use mode of the card and make various effective uses.

For example, by inserting an expiration date, it is possible to automatically invalidate the card when the expiration date has expired. Unauthorized use can be prevented. In addition, by setting the security level on the card, the setting of the fingerprint collation device itself can be automatically reduced to lower the false rejection rate (decreasing the false rejection rate increases the false acceptance rate) or lowering the false acceptance rate (lowering the false acceptance rate). If it is lowered, the rejection rate will increase).

The present invention is not limited to the case where the identity of a person is identified at a bank or a government office as described above. For example, the identity of a credit card, a card-type electric lock at a hotel or the like, or a member It can also be applied to entry and exit management of system clubs.

That is, as for the identification of the credit card, for example, by registering fingerprint data in the credit card, it is necessary to confirm that the person is currently signed and that the face photograph is judged by the person, and the judgment standard is ambiguous. The judgment criteria can be clarified because the judgment can be made by the fingerprint collation device (machine).

When a card-type electric lock is used in a hotel or the like, if a card in which fingerprint data is registered is used as a key for a room in a hotel or the like, if the card is lost or stolen, Also, since a person other than the person cannot unlock the lock, a highly secure system can be created.

Further, in the case of use for entry / exit management of a membership club, if fingerprint data is recorded on the membership card of the club, there is an advantage that unauthorized use by others can be prevented.

[0027]

As described above, the fingerprint recognition apparatus according to the present invention records the fingerprint data of the person in advance on the card, and compares the fingerprint data recorded on the card with the fingerprint data of the person who brought the card. Then, it is determined whether or not the user is the principal, so that it is not necessary to register and store the fingerprint data in each fingerprint collation device or the like as in the related art, and the device configuration, the management of the fingerprint data, and the device configuration are greatly reduced. In addition to being able to simplify, the number of people who can register is limited by the number of people who can use the fingerprint collation device in the past, but according to the present invention, the number of people who can use the fingerprint collation device and the trouble such as pre-registration of fingerprint data are eliminated. be able to.

Further, in the conventional fingerprint collation apparatus, since the collation target is performed for all the registered data, as the number of registered data increases, the acceptance rate of others (the identity of a person who is another person) increases. However, according to the present invention, since the data to be verified is only the data registered in the card, the verification can be performed easily and quickly, and the acceptance rate of others does not change regardless of the number of users. And the like.
