DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a certificate having a personal identification function in which a plurality of registrants are posted, such as a health insurance card, and an improvement of an identity verification system using the certificate.

[0002]

2. Description of the Related Art Various types of identification cards, such as driver's licenses and passports, have conventionally been used as a certificate having a personal identification function. A face photograph is added as identification information to these certification slips. However, since the face changes with age, it is necessary to update the face periodically in order to ensure the validity as identification information.

On the other hand, Japanese Patent Application Laid-Open No. 2-88778 discloses a consultation ticket card in which a fingerprint of a person is printed on a card as identification information. Fingerprints are information unique to each individual and can be considered to not change with age, and therefore are superior as identification information to face photographs.

[0004] In each of the above-mentioned licenses and consultation ticket cards, information of one person is recorded for one certificate. On the other hand, a health insurance card in which there are multiple owners per certificate voucher has columns for the insured and dependents, and for each medical benefit record. At present, personal identification information for confirming whether the user is a proper person is not attached.

[0005]

For this reason, with the current health insurance card, it is not possible to confirm whether or not the person who brought the health insurance card is the insured or dependent person described. If a health insurance card is handed over to another person, there is a possibility that the other person will be disguised as the person and present the health insurance card and receive medical treatment, or the health insurance card will be misused as a means of identification .

[0006] Further, in the medical examination ticket card disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 2-88778, the fingerprint image itself is recorded as visible information so that it can be observed with the naked eye.
There is a possibility that a person who picks up such a consultation ticket card may rewrite the fingerprint image with his / her own fingerprint image and use it improperly.

The present invention has been made in view of the above-mentioned problems of the prior art, and a first object of the present invention is to provide a certificate such as a health insurance card in which a plurality of registrants are present on one certificate. This is because the vote has an identity verification function. Also, the second
It is an object of the present invention to provide a certificate that is less likely to rewrite registered information for identifying a user. further,
A third object is to provide an identity verification system having such a function.

[0008]

In order to solve the above-mentioned problems, a certificate voucher according to the present invention is a certificate voucher in which information of a plurality of registrants is recorded. The information on physical characteristics was configured to be printed in invisible ink for all registrants. in this case,
The information on the physical characteristics unique to the registrant can be printed as image data with invisible ink. Further, information on the physical characteristics unique to the registrant may be printed with invisible ink as numerical data extracted from those characteristic amounts. Further, the information may be printed with invisible ink using fingerprint information as information on physical characteristics unique to the registrant. When using the fingerprint information of each registrant as the information on the physical characteristics unique to the registrant, the invisible ink was applied to a thin film using wax as a binder in the form of fine particles and in a planar shape. It is desirable to print using an invisible ink ribbon. Further, in the case of an identity verification system using a certificate printed with invisible ink, information on physical characteristics unique to each registrant is recorded as information for identifying a plurality of registrants, A feature amount input unit that reads the physical characteristics of the verified person among the plurality of registrants described in the certificate, a print information input unit that reads information about the physical characteristics printed on the certificate, Comparing means for comparing the actual information on the physical characteristics input by the feature amount input means with the record information input by the print information input means to determine whether the confirmed person is a registered person. What is necessary is just to provide and comprise. Also in this case, the fingerprint information of each registrant can be used as the information on the physical characteristics.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a certificate voucher having a personal identification function in which a plurality of registrants are posted according to the present invention will be described below. 1 and 2 show an embodiment in which the present invention is applied to a health insurance card.
Is an example of using a paper health insurance card (hereinafter referred to as a health insurance card) similar to the present as a certificate, and FIG. 2 shows an example of a plastic health insurance card.

The health insurance card 10 shown in FIG. 1 is provided with three pages as shown in FIG. 1 on the front side and a medical payment record column on the back side (not shown). The center page 11 on the front side contains text information on the insured person, business office, and prefecture, and the right page 1
2, character information about the dependent is described. Here, the insured person and the dependents are registrants of the health insurance card. On the left page 13, columns A1, A2,... For listing the names of registrants and information on their unique physical characteristics are used as information for confirming the identity of the insured and dependents. Fields B1, B2, ... for printing fingerprint image information
・ Is prepared for all registered persons.

On the other hand, in the health insurance card 20 shown in FIG.
In the upper part of the figure, a field for printing the name of the registrant and a lower part for printing the fingerprint of each registrant are provided. With a card-type health insurance card,
Character information other than the name is recorded as magnetic information on a magnetic strip provided on a part of the card.

By printing fingerprint information as image information or digitized information in each fingerprint printing column, this fingerprint information can be used as identification information for identifying a person, so that health insurance Easily identify whether the submitter is a registrant on the health insurance card by comparing the information obtained from the actual fingerprint of the person submitting the certificate with the printed registered fingerprint information And prevent unauthorized use of the health insurance card.

In addition, since the fingerprint information of the registrant is printed on each health insurance card, it is used as a hospital or identity card when used on the confirmer side, that is, when a medical fee is paid, which is the original purpose of use. In this case, for example, there is no need to construct a database for associating fingerprint information with names at government offices or banks, and a system can be constructed at relatively low cost.

Next, an apparatus and a procedure for printing fingerprint information on a health insurance card as described above will be described. FIG. 3 shows an outline of an apparatus for printing registrant fingerprint information on a health insurance card. The apparatus includes a fingerprint input device 30 that optically reads a fingerprint of a registrant's finger and outputs the image data as image data, and an image processing device 40 that processes the image data into print data.
And a fingerprint information printing device 50 that prints fingerprint information on a health insurance card based on print data.

The fingerprint input device 30 includes a contact glass 3
1, a light source 32 for illuminating the finger F placed on the top from below,
Lens 33 which forms a fingerprint image by reflected light from
And a band pass filter 34 for cutting unnecessary wavelengths, and an image sensor 35 such as a CCD area sensor for reading a fingerprint image.

The image processing device 40 outputs fingerprint information as image data or numerical data based on the image data output from the image sensor 35. The fingerprint information printing device 50 includes a thermal head 51, an invisible ink ribbon 54 passed between a pair of ribbon rollers 52, 53,
A feed roller 55 for feeding the health insurance card 10 to the thermal head 51 in the direction of the arrow in the figure is provided.

FIG. 4 is a flowchart showing a procedure for printing fingerprint information on a health insurance card using the above-described device. When registering a fingerprint, fingerprint image data is read by the fingerprint input device 30 in step S1. The image processing device 40 converts the fingerprint image data input in step S2 into 2
It prints different data according to the recording mode.

The recording modes include a feature amount recording mode in which a feature amount is extracted from image data and printed as numerical data, and an image recording mode in which a binarized fingerprint image is printed as it is. If it is determined in step S3 that the mode is the feature recording mode, the feature as a fingerprint figure is extracted from the binary image data in step S4, and the fingerprint information printing device 50 is controlled in step S5. The feature amount is printed as numerical data using a format such as a barcode. If the recording mode is the image recording mode, the binarized fingerprint image is printed in step S6.

FIG. 5 shows an apparatus and a procedure for comparing fingerprint information printed on a health insurance card with a fingerprint of a person to be confirmed.
This will be described with reference to FIG. The collation device placed on the confirmer side is
As shown in FIG. 5, a print information reading device 6 for reading fingerprint information printed on a health insurance card as image data.
0, a fingerprint input device 30 similar to FIG. 3 for reading actual image data of a fingerprint of a person to be confirmed, an image processing / control device 61 for processing and collating images input from these devices,
And a display device 62 for displaying the collation result.

The collation is performed according to the flowchart shown in FIG. In step S11, the fingerprint input device 30
When a real fingerprint image is input from the, steps S12 and S1
In step 3, the fingerprint actual image data is binarized to extract a feature amount. Next, it is determined in step S14 whether the fingerprint information printed on the health insurance card is numerical data of the feature amount or image data of the fingerprint itself. If the feature amount is recorded, printing is performed in step S15. The data related to the obtained feature amount is input, and this is compared with the feature amount of the real image obtained in S13 in S16.

If the fingerprint information is printed as image data, the registered fingerprint image data printed in S17 is input, and in step S18, a feature amount is extracted from the data. In step S19, the feature amount extracted in S18 is compared with the feature amount of the real image obtained in S13.

In any mode, step S2
In step 0, it is determined whether or not the feature amount of the fingerprint information printed on the health insurance card matches the feature amount of the actual image of the fingerprint input at the time of confirmation. Is displayed on the display device 62 so as to approve the use of the health insurance card in S21. On the other hand, if the two feature amounts do not match, the confirmed person is different from the registrant, so that the display is made on the display device 62 so as to reject the use of the health insurance card.

In the feature amount recording mode, although an extraction operation is required at the time of registration, it is possible to save time and effort for extracting a feature amount from registered fingerprint data at the time of collation, thereby improving the efficiency of the confirmation operation. Considering that the registration is performed once, but the collation is required for each confirmation, recording in the feature amount recording mode can improve overall efficiency. However, if the image is recorded in the image recording mode, it is possible to perform collation with the naked eye without using the collation device. Can expand the range of use.

By configuring the registration and collation system as described above, unauthorized use by a third party other than the registrant of the health insurance card can be accurately prevented. If a password is used in combination with fingerprint information as confirmation means, security against unauthorized use can be further increased.

When recording image information on a card, an image can be recorded invisible to human eyes by printing using invisible ink. The term “invisible” in the invisible ink means an object that cannot be seen by human eyes, and here refers to a region of light (electromagnetic wave) having a wavelength other than visible light. The visible light range is from about 380 nm to 7
80 nm, and there is a wide invisible area on both sides. When the image is printed with the invisible ink as described above, it is difficult to perform an illegal act such as rewriting the image data, so that the possibility of unauthorized use of the card can be reduced.

FIG. 7 is a sectional view showing a specific example of the invisible ink ribbon 54 shown in FIG. Here, the invisible ink 71 is in the form of fine particles, and is applied in a plane on the base paper 73 using wax (WAX) as a binder 72. Here, the base paper 73 has a thickness of about 6 to 9
μm, and PET or the like can be used as a material. The invisible ink ribbon 54 is wound in a roll as shown in FIG. The application amount of the invisible ink is 1
About 3 grams per square meter is a reasonable amount. An image can be printed with invisible ink by setting such an ink ribbon on the fingerprint information printing apparatus 50 and transferring the ink ribbon with a thermal head.

The invisible ink used in the present embodiment is
It is a material in the above-mentioned invisible wavelength band. As a material of the invisible ink 71, a phosphor that emits infrared light such as a rare earth element, a transition metal, or a group IIIb, or an infrared light such as a trifluoride compound of yttrium Y, erbium Er, or ytterbium Yb is used to emit visible light. A phosphor that emits light, a phosphor that emits visible light when irradiated with ultraviolet light, or the like can be used.

These invisible inks are excited by irradiating light of a predetermined wavelength, and emit fluorescent light of a wavelength different from the incident light. When an image is printed with ink that emits infrared light, the natural light impinges on it, causing infrared light that is invisible light to be emitted. Read the image using. At this time, it is desirable to use a bypass filter to cut off light having a wavelength other than infrared light necessary for reading. When an image is printed with ink that emits visible light when irradiated with infrared rays or ultraviolet rays, the image cannot be observed with the naked eye under natural light. When irradiated with light of each specific wavelength, the ink emits visible light so that the image can be recognized by the naked eye and read using a CCD or amorphous Se avalanche target (HARP imaging tube) with sensitivity in the visible region. Can be.

The present invention is applicable not only to the health insurance card described in the above embodiment, but also to a certificate such as a credit card company card or a family card having a plurality of owners per certificate. can do.
In addition, as the unique physical characteristics, not only the fingerprint described above but also a pattern of capillaries of a retina or a finger, a palm, or the like can be used.
