BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ID card, a personal identification system and a method thereof.

[0002]

2. Description of the Related Art A conventional ID card has a structure as shown in FIG. 9, and a face photograph 4 of the owner and character information 5 for identifying the owner are directly added to the ID card 3 (a). They were pasted, (b) a part of the ID card 3 was cut out and fitted, and (c) the ID card 3 was cut out.

Further, in a personal authentication system that handles a large number of ID cards, when collation is performed to determine the authenticity of the ID cards, as shown in FIG.
20b, ..., 20n via the personal authentication system 21a,
The inquiry was made to the center 19 connected to 21b, ..., 21n. However, the conventional ID card described above has the following drawbacks. (A) It can be easily forged. When the method of directly pasting on the ID card 3 is adopted, it can be easily counterfeited by means such as replacing the facial photograph 4. (B) The privacy of the owner cannot be protected. The ID card 3 as shown in FIG. 9 may violate the privacy of the owner.

(C) In the network-based personal authentication system, the communication control unit 2 is affected by a network failure.
When the 0a, 20b, ..., 20n are stopped, the IDs are obtained by the personal authentication systems 21a, 21b ,.
The card cannot be authenticated. for that reason,
Japanese Laid-Open Patent Publication No. 3-193495 proposes an ID card provided with specific anti-counterfeit information in the face photograph area in order to prevent forgery.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a view showing the structure of the back surface of the ID card 1. On the back surface of the ID card 1, face photograph information for identifying the owner and characters for identifying the owner are shown. A two-dimensional barcode 2 having information and security information as data is attached. It should be noted that conventional face information and personal information as shown in FIG. 9 are pasted on the surface of the ID card 1.

FIG. 2 shows the ID card 1 described above.
It is a figure which shows the structure of the system which reads the two-dimensional barcode 2 from the produced ID card 1 and performs personal authentication.
In the figure, the system bus 6 includes a CPU 7, a memory 8, an external storage device 9 such as a magnetic disk, a CRT and an LCD.
Display device 10, A / D converter 11, keyboard 1, etc.
A three-dimensional and two-dimensional bar code reader 14 and a printer 15 such as a thermal dot printer are connected. Furthermore, A /
A camera 12 is connected to the D converter 11.

The case of creating the two-dimensional bar code 2 will be described below with reference to the flow charts of FIGS. 1, 2 and 6 described above. Here, each step is simply indicated by S.

First, facial photograph data photographed by the camera 12 is converted into digital image data by the A / D converter 11 and temporarily stored in the memory 8 via the system bus 6 (S1, S2, S3). Where the camera 12
Is a digital camera, the A / D converter 11 is unnecessary, and in this case, the data from the camera 12 is directly taken into the memory 8. Next, the image data captured in the memory 8 is stored in the external storage device 9 under the control of the CPU 7.
Is stored as a color or monochrome image file (S4), and then the image file is displayed on the display device 10 using the image file display program under the control of the CPU 7 (S5).

Next, the personal information corresponding to the face photograph as the image data displayed in the personal information input box on the display device 10 is input from the keyboard 13 (S6). Next, CP
Under the control of U7, a two-dimensional barcode file in which the image data on the display device 10 and the personal information data are combined is created and stored in the external storage device 9 (S7). Then C
Using the two-dimensional barcode printing program under the control of the PU 7, the two-dimensional barcode file stored in the external storage device 9 is converted into two-dimensional barcode data,
A two-dimensional barcode is printed by the printer 15 (S
8). Two-dimensional barcode 2 created in this way
Is attached to the back surface of the ID card 1 as shown in FIG.

A case where the ID card with a two-dimensional bar code 1 is authenticated using the system shown in FIG. 2 will be described below with reference to the flowcharts of FIGS. 1, 2 and 7. First, the two-dimensional bar code reader 14
Scan the two-dimensional barcode 2 on the D card 1 (ST
1). The read two-dimensional bar code data is once stored in the memory 8 and then stored in the external storage device 9 (ST2). Next, the face photograph data and the personal information data are separated under the control of the CPU 7, and each is displayed on the display device 10 using the display program (ST.
3). See the display screen 16 shown in FIG. by this,
The face photograph 17 and the personal information 18 of the owner of the ID card 1 registered in the two-dimensional barcode 2 can be seen.

The second embodiment will be described below with reference to FIG. Also in this embodiment, as in the first embodiment,
The two-dimensional bar code 23 created by using the ID card creating method described in the first embodiment is attached to the back surface 22 of the ID card, except that the owner's handwriting signature 24 is the two-dimensional bar code. That is what was written above the code 23. In this embodiment as well, authentication can be performed by the same personal authentication method as in the first embodiment, but the forgery prevention effect is further improved.

The third embodiment will be described below with reference to FIG. In this embodiment, the ID card surface 25
Then, the two-dimensional barcode 26 created by the ID card creating method described in the first embodiment is attached. In this case, a face photograph and personal information (Fig.
Since 4) and 5) are not provided, when performing personal authentication,
The face photograph and personal information displayed on the display device 10 and I
This will be done by comparing with the face of the owner of the D card. As described above, according to the above-described embodiment, the following effects can be obtained.

In the first and second embodiments, the conventional ID
Since the face photograph 4 attached to the card 3 is compared with the face photograph 17 on the display device 10 obtained by reading the two-dimensional barcode 2 using the two-dimensional barcode reader 14, the ID card is a real one. You can tell if it exists and prevent counterfeiting.

The face photograph 17 on the display device 10 obtained by reading the two-dimensional bar code 2 by the two-dimensional bar code reader 14 is compared with the face of the owner so that the center 19 is not inquired. Authentication is possible.

In the third embodiment, the information about the owner cannot be viewed unless the two-dimensional bar code reader 14 reads the two-dimensional bar code 26, which is advantageous in that privacy is maintained.

[0024]

As described in detail above, according to the present invention,
Since the face photograph, personal information, etc. are expressed by a two-dimensional bar code, it is possible to prevent forgery with a simple card structure and perform personal authentication on the spot.
