Description

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

[Conventional technology]

2. Description of the Related Art IC cards that have a built-in IC memory (including an LSI memory that writes and reads data using magnetic signals) and that store a large amount of information are being put into practical use.

Since conventional IC cards cannot identify the holder and the user, there is a risk that they may be misused. Therefore,
The present inventor has proposed an IC card in which a photograph of a person is enclosed within the card so that the owner can be identified (
(Patent Application No. 82223/1982).

[Problem that the invention seeks to solve]

However, even with this IC card containing a photograph of a person, there is a problem in that if the photograph of the person is replaced, misuse cannot be detected.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide an IC card that allows easy detection of tampering due to replacement of portrait photographs.

[Means for solving problems]

In order to achieve the above object, the present invention is characterized in that a person's image is displayed on an IC card, and characteristic information of the person is stored in a built-in IC memory.

[Effect]

Characteristic information of a person is stored in a part of the IC memory, so by reading this information, it is possible to know the characteristics of the owner. Therefore, by checking this characteristic information, it is possible to discover whether the portrait photos have been replaced.

The characteristic information includes a photograph of a person and a line drawing of a fingerprint.

There is text information etc. This text information includes, for example, height and weight, presence or absence of glasses, eye color and size, and hair color.

There are fingerprint shapes (vortex, hoof, etc.).

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

[Example] In FIGS. 1 and 2, the color photographic paper 1 is
In order to prevent curling, a thin material of 100 to 190 μm is used, and a person image 1a, a character image 1b representing personal information such as a name, a graphic image 10, etc. are printed on the printed surface. There is. This color photographic paper 1 is
An image of a person captured by a TV camera and a name entered using a key, for example.

A computer is used to synthesize characters representing personal information such as age, the resulting composite image is displayed on a CRT, printed on color photographic paper, developed, and then punched out to a specified size. .

In order to prevent the color photographic paper 1 from bulging out, a frame sheet 2 made of white or transparent polyvinyl chloride is used, and the color photographic paper 1 is fitted into a large opening 2a formed in the frame sheet 2. This frame sheet 2 is preferably approximately the same thickness as the color photographic paper 1 in order to make the card flat. A white polyvinyl chloride core sheet 3 is bonded to the lower surface of the frame sheet 2.

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

In order to strongly adhere the first oversheet 4 and the color photographic paper 1 so that they do not peel off even when the card is squeezed, a colorless and transparent adhesive layer 7 having heat sealing properties is used to bond them together. is glued. This adhesive layer 7
is formed in advance on the print surface of the color photographic paper 1, but may be formed on the first oversheet 4 instead.

In addition to information according to the purpose of use of the card, the IC memory 10 has written therein characteristic information of a person, such as line drawing information of a portrait, in order to detect tampering. This line drawing information is created using a TV camera and an image processing device. That is, a photograph of a person is taken with a TV camera, the obtained video signal is converted into a digital signal, and then written into an image memory. next,
One contour part, eyes, and nose from the still original image stored in the image memory.

The mouth etc. are extracted to create line drawing data, and this line drawing data is written to IC memory 0.

In order to attach the IC memory 10, an opening 2b is formed in the frame sheet 2, and an opening 3a is formed in the core sheet 3. The frontage 2b and the opening 3a are
They have circular shapes of the same size, and the IC memory 10 is housed inside them.

The first oversheet 4 has an opening 4a smaller in size than the upper surface of the IC memory 10 in order to prevent the IC memory 10 from falling off and to expose the contacts 11. In addition, the second oversheet 5 and the IC memory 10
An adhesive layer 13 having heat-sealing properties is used to strongly adhere the cards and prevent them from peeling off even when the card is squeezed. This adhesive layer 13 is
Although it is applied in advance to the back surface of the C memory 10, it may be formed on the second oversheet 5 instead.

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

Each of the stacked sheets is inserted between a pair of ferro plates whose surfaces are plated with chrome.

By pressurizing and heating this ferroplate, each sheet is joined and integrated. This heating temperature is, for example, 14
0~150°C, press pressure 10~15kg/c
+fl. After thermocompression bonding, the card is naturally or forcedly cooled until it becomes hard, and then punched out with a punching cutter to create a photo card 12.

FIG. 3 shows a card reading device.

The photo card 12 is set in the card reading device 15 when writing or reading data. When the photo card 12 is set in a predetermined position, the contact device 16 connects to the IC.
It contacts the contacts 11 of the memory 10 and connects the computer 17 and I.
c memory 10 is connected. This computer 17 first reads line drawing information stored in the IC memory 10 and sends it to the synthesis circuit 18.

On the other hand, a TV camera 19 is provided in the card reading device 15, and a photo image 1 of the photo-containing IC card 12 is provided.
Take an image of a. The video signal output from the TV camera 19 is sent to an image processing circuit 20, where it is subjected to digital conversion, 1-gradation processing, etc., and then sent to the synthesis circuit 18. This synthesis circuit 18 synthesizes the line drawing information output from the computer 17 and the person image captured by the TV camera 19, and displays the result on the display surface 20a of the CRT 20 via the CRT controller 19.

FIG. 4 shows a composite image displayed on a CRT. On the display surface 20a of the CRT 20, an image 21 obtained by capturing the person image 1a of the photo IC card 120 and a line drawing 22 read out from the IC memory 10 are displayed side by side. By observing these two images 21 and 22, if they do not match, it can be determined that the portrait photographs have been exchanged. If the two images 21 and 22 match, the operator operates a key (not shown) provided on the card reader 15 to read the computer 17.
■Connect to a host computer (not shown). The host computer reads data stored in the IC memory 10, or sends and writes data to the IC memory 10.

In the above embodiment, the line drawing information of the portrait is stored in the IC memory, but instead of or in addition to this, line drawing information of the fingerprint, height, weight, eye size and color, hair color, and fingerprint shape are also stored. Write text information such as
It may be displayed as 0.

Furthermore, although photographic paper on which a photograph of a person is recorded is used as the display sheet, it is also possible to coat a core sheet with a light-sensitive emulsion and directly print the person on the core sheet without using this photographic paper.

〔Effect of the invention〕

As explained in detail above, according to the present invention, since the characteristic information of a person is written in the IC memory, by reading out this characteristic information, card tampering such as replacing the photograph of the person can be easily detected. Misuse of the card can be prevented.
