Abstract

PURPOSE:To reduce the danger for misuse of an ID card by collating the feature point data on the user's own fingerprint with that on the user himself/herself stored in an external memory device. CONSTITUTION:The ID number recorded on an input ID card is read and sent to a fingerprint collator 3. The collator 3 retrieves the feature point data registered to an external memory device 2 based on the received ID number and collates the feature point data read out of the device 2 with that received from a direct fingerprint scanner 1 and sends the result of this collation to a terminal equipment 5. Then the fingerprint image received from the scanner 1 is sent to an ID card device 4 via the collator 3. The device 4 contains a function to print the received fingerprint image onto the ID card. While the equipment 5 displays the result of collation and various indications are inputted to the collator 3 from the equipment 5.

〔Example〕

The present invention will be explained below with reference to Examples.

Referring to FIG. 1, a personal verification recognition system according to the present invention includes a direct fingerprint scanning device 1, an external storage device 2, a fingerprint verification device 3, and an ID card device 4.

and a terminal device 5.

The fingerprint direct scanning device 1 directly reads a fingerprint image and extracts minutiae from this fingerprint image.

These fingerprint images and minutiae data are then sent to the fingerprint matching device 3. The external storage device 2 is.

The magnetic file is constituted by a memory element, and feature point data is stored in advance in correspondence with an ID number.

The card device 4 can record more information on the card.
Equipped with a function to read D numbers and issue ID cards.

Then, when an ID card is input, the ID number recorded on the ID card is read.

Send it to the fingerprint matching device 3. The fingerprint verification device Roha-Uke searches for minutiae data that is registered in the external storage device 2 based on the received number and retrieves the minutia data read from the external storage device 2 and the minutiae data read from the fingerprint direct scanning device 1. The fingerprint image from the fingerprint direct scanning device 1 is sent to the matching device 3.
is sent to the ID card device 4 by. The card device 4 has a function of printing the fingerprint image taken on the card. The terminal device 5 displays the verification results, and on the other hand, various instructions are input from the terminal device 5 to the fingerprint verification device 6.

Next, the bell ringing process will be explained with reference to FIGS. 1 and 2.

First, instructions for registration (ID number, etc.) are input from the terminal device 5 (step 201).

Place one arbitrary finger of the user on the scanning surface of the fingerprint direct scanning device 1 and read the fingerprint image directly (step 20
2). The fingerprint direct scanning device 1 is.

Feature points are extracted from the read fingerprint image (step 203). Then, the feature point data extracted via the fingerprint matching device 6 is registered in the external storage device 2 in correspondence with the ID number input from the terminal device 5 (step 204).
). A card with the card number input from the terminal device 5 recorded is issued by the ID card device 4 (step 205).

In addition, if necessary, a fingerprint image can be added to the ID card as an ID.
Printed with the number.

Next, the collation/update process will be explained with reference to FIGS. 1 and 2.

First, an instruction to either verify or update the terminal device 5 is input (step 301).

In the case of verification, the ID card is inserted into the ID card device 4 (step 302). If the ID card has an expiration date, the ID card device 4 first checks whether the card is within the expiration date (step 303). As a result, if the ID card has expired, the process moves to an update process to be described later.

On the other hand, if the ID card is within its expiration date, search and verification processing (304) is performed. First, a fingerprint image of a user's finger is read by the fingerprint direct scanning device 1 (step 401), and feature points are extracted from this fingerprint image (step 40).
2). The fingerprint verification device 6 searches for feature point data registered in the external storage device 2 based on the ID number read by the ID card device 4 (step 406).

If the search fails, that is, if the feature point data corresponding to the ID number is not registered in the external storage device 2 (step 404), that fact is displayed on the terminal device 5 (step 405). If successful (step 404), the fingerprint verification device 3 compares the extracted minutiae data with the retrieved minutiae data (step 406).
).

The verification result is displayed on the terminal device 5 (step 305).

Then, the user inserts the card into the card device 4.
It is then returned (step 306).

On the other hand, in the case of update processing, the ID card is input into the ID card device 4 (step 307). The ID card device 4 records the number on the card and reads the number (step 308).
If the ID card is determined to have expired in step 03, the process moves to step 308, but in this case, the card device 4
Do not read the number on the D card. Therefore,
A user inputs an ID number from the terminal device 5. Thereafter, search and matching processing (309) is performed. This search and matching process (309) is similar to the above-mentioned search and matching process (304), so the explanation will be omitted. As a result of the search matching process (j09), if matching of feature point data is confirmed (step 31
0).

The newly determined card number is recorded on the card by the ID card device 4, and the new card is handed over to the user (step 311). On the other hand, if it is confirmed that the feature point data do not match, this fact is displayed on the terminal device 5 (step 605). Note that in the case of update processing, step 06 is not performed (.

In this manner, in the verification process, the external storage device 2 is searched using the ID number recorded on the card, and the retrieved minutiae data is collated with the minutiae data of the user's fingerprint image. 2. Perform personal identification.

On the other hand, the update process is a process that is performed when the user updates the ID card (in the case of a certain degree), the card has an expiration date and this expiration date has passed.

In the update process, the person updating the card must first insert the ID card into the
It is inserted into the D card device, and the feature point data of the user's fingerprint image is compared with the feature point data searched using the ID number recorded on the ID card or the ID number input from the terminal device 5 (・Based on the matching results (
·hand.

A new ID card with a new number recorded will be issued. Note that a fingerprint image is printed on the new ID card if necessary.

By the way, ID card issuance in registration process.

And in the renewal process and new card issuance,
In this way, when a fingerprint image processed by the fingerprint direct scanning device 1 is printed on a card, a verification process can be performed by comparing the fingerprint printed on the ID card and the person's fingerprint. Therefore, individual identification can be easily performed.

〔Effect of the invention〕

As explained above, the present invention has the effect of improving the user's ability to recognize individuals compared to conventional personal verification systems.

For example, if the number recorded on the card is read, or even if the card is forged, the fingerprint minutiae data of the two individuals and the data registered in the external storage device 2 will be used for verification. (Since the card can be compared with the person's feature point data, the risk of the card being misused can be further reduced.Also, by printing the person's fingerprint image on the ID card, it is possible to easily identify the person.) There is also.
