Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement of a photo IC card.

[Conventional technology]

IC cards (including an LSI memory that writes and reads by magnetic signals) are built into the card, and IC cards that store a large amount of information are being put to practical use. Since the conventional IC card cannot distinguish the owner and the user, there is a risk of misuse. Therefore, the present inventor has proposed an IC card in which a photograph of a person is enclosed in the card so that the owner can be specified (Japanese Patent Application No. 61).
-82223).

[Problems to be solved by the invention]

However, even with this IC card enclosing the portrait, there is a problem that the abuse cannot be found if the portrait is replaced.

[Object of the Invention]

It is an object of the present invention to provide an IC card in which tampering due to replacement of portrait photographs can be easily found.

[Means for solving problems]

In order to achieve the above object, the present invention displays an image in which a character image and a photograph image of a person are combined on an IC card, and the line drawing information of the photograph image is collated with the photograph image in an IC memory incorporated therein. It is stored as information.

[Action]

Since the line drawing information of a person's photo image is stored as collation information with the photo image, when using the IC card, this line drawing information is read and the line image is displayed and collated with the photo image so that the person photo on the IC card can be displayed. It is easy to find out if they have been replaced.

Embodiments of the present invention will be described below with reference to the drawings.

〔Example〕

In FIGS. 1 and 2, as the color printing paper 1, a thin one of 100 to 190 μ is used in order to prevent the occurrence of curling, and the person image 1a and personal information such as name are printed on the printed surface. A character image 1b representing "," a graphic image 1c, and the like are printed. This color photographic paper 1 is composed of a person image captured by a TV camera and characters representing personal information such as name and age entered by a key using a computer, and the composite image is displayed on a CRT. It is printed on a color photographic paper, developed, and then punched to a predetermined size.

In order to prevent the color photographic paper 1 from bulging, a white or transparent polyvinyl chloride frame sheet 2 is used, and the color photographic paper 1 is fitted into a large opening 2a formed in the frame sheet 2. The frame sheet 2 preferably has substantially the same thickness as the color photographic paper 1 in order to flatten the card. A white polyvinyl chloride core sheet 3 is joined to the lower surface of the frame sheet 2.

A transparent polyvinyl chloride first oversheet 4 is bonded to the upper surface of the frame sheet 2, and a transparent polyvinyl chloride second oversheet 5 is bonded to the lower surface of the core sheet 3.
Are joined. The magnetic stripe 6 is bonded to the upper surface of the first oversheet 4.

The first oversheet 4 and the color photographic paper 1 are strongly adhered to each other with a colorless and transparent adhesive layer 7 having heat sealability so that they are not peeled off even when the card is squeezed. Are glued together. Although the adhesive layer 7 is formed in advance on the print surface of the color photographic paper 1, it may be formed on the first oversheet 4 instead.

In the IC memory 10, in addition to information according to the purpose of use of the card, line drawing information of a person photograph, which is characteristic information of a person, is written in order to detect tampering. This line drawing information is created by the TV camera and the image processing device. That is,
An image of a person is taken by a TV camera, the obtained video signal is converted into a digital signal, and then written in the image memory. Next, the outline, eyes, nose, mouth, etc. are extracted from the still original image stored in the image memory to create line drawing data, and this line drawing data is created by the IC.
Write to memory 10.

In order to mount the IC memory 10, the frame sheet 2 has an opening 2b and the core sheet 3 has an opening 3a. The opening 2b and the opening 3a have the same circular shape, and the IC memory 10 is housed in them. The first oversheet 4 prevents the IC memory 10 from falling off and exposes the contacts 11 so that the IC memory 10 is not exposed.
An opening 4a having a size smaller than the upper surface of is formed.
Further, an adhesive layer 13 having a heat-sealing property is used so that the second oversheet 5 and the IC memory 10 are strongly adhered to each other so that they are not peeled off even when the card is squeezed. Although the adhesive layer 13 is applied to the back surface of the IC memory 10 in advance, it may be formed on the second oversheet 5 instead.

When making a card with a photo, first, the frame sheet 2
The color photographic paper 1 is fitted into the opening 2a of the above, and this is stacked on the core sheet 3. After stacking these on the second over sheet 5, the IC device 10 is fitted into the recess formed by the opening 2a of the frame sheet 2 and the opening 3a of the core sheet 3. Finally, the first oversheet 5 is overlaid on the frame sheet 2 so that the opening 4a is located above the contact 11.

Each of the stacked sheets is inserted between a pair of chrome plates whose surfaces are plated with chrome. By pressing and heating the ferroe plate, the sheets are joined and integrated. The heating temperature is, for example, 140 to 150 ° C., and the pressing pressure is 10 to 15 kg / cm ² . After thermocompression bonding, the card is naturally or forcibly cooled until it becomes hard, and then punched with a punch cutter to prepare a card 12 with a photograph.

FIG. 3 shows a card reader. The photo card 12 is set in the card reader 15 when writing or reading data. When the photo card 12 is set in place, the contact device 16 causes the contact 11 of the IC memory 10 to
Then, the computer 17 and the IC memory 10 are connected to each other. The computer 17 first reads the line drawing information stored in the IC memory 10 and sends it to the synthesizing circuit 18.

On the other hand, a TV camera 19 is provided in the card reading device 15, and picks up a photographic image 1a of the photo IC card 12. The video signal output from the TV camera 19 is sent to the image processing circuit 20, where it is subjected to digital conversion, gradation processing, etc., and then sent to the synthesizing circuit 18. This synthesis circuit 18
Is the line drawing information and TV camera output from the computer 17.
CRT controller 19
Is displayed on the display surface 20a of the CRT 20 via.

FIG. 4 shows a composite image displayed on the CRT. On the display surface 20a of the CRT 20, an image 21 of the person image 1a of the photo IC card 12 and a line drawing 22 read from the IC memory 10 are displayed side by side. When these two images 21 and 22 are observed, and if they do not match, it can be determined that the person photographs have been replaced. Two
If the two images 21 and 22 match, the operator operates a key (not shown) provided on the card reading device 15 to operate the computer 17 as a host computer (not shown).
1 connect. The host computer reads the data stored in the IC memory 10 or sends the data to the IC memory 10 to write it.

In the above embodiment, the line drawing information of the portrait is stored in the IC memory.
Character information such as weight, size and color of eyes, hair color, and fingerprint shape may be written and displayed on the CRT 20.
Further, although a photographic paper on which a photograph of a person is recorded is used as a display sheet, a photosensitive emulsion may be applied to the core sheet and a person may be directly printed on the core sheet without using the photographic paper.

〔The invention's effect〕

As described in detail above, according to the present invention, an image obtained by combining a character image and a photo image of a person is displayed on an IC card, and the line memory information of the photo image is stored in a built-in IC memory as a photo image. Stored as the collation information of
By reading this line drawing information when a card is used, displaying the line drawing, and collating the photo images, it is possible to easily find out whether or not the person photo on the IC card has been replaced, and prevent misuse of the card. You can

Moreover, first, the photo image displayed on the IC card and the line drawing based on the line drawing information stored in the IC memory can be used to verify the authenticity of the photo image, and then the photo image and the IC card owner can be verified. Therefore, the matching accuracy can be improved. That is, the collation between the line drawing and the photographic image based on the line drawing information stored in the IC memory is easier than the comparison between the person itself and the line drawing, and the collation accuracy does not deteriorate. Moreover, after this collation, in order to collate the photo image displayed on the IC card with the IC card holder,
The comparison is easier than the comparison between the person and the line drawing and the comparison between the person and the reproduced image based on the image data stored in the IC memory, and the collation can be performed more reliably. In this way, when a line drawing is directly collated with the IC card holder, or when the redevelopment of the person image stored in the IC card memory and the IC
Compared with the case of directly comparing with the card holder, the two-stage matching, which is easier to compare, can be performed, and the matching accuracy is improved. Further, since the line drawing information is used as the collation information, the total amount of data for collation can be reduced, and the memory capacity used for the original purpose of the IC card is not pressed.
