DESCRIPTION OF THE PREFERRED EMBODIMENTS A card authentication system according to the present invention comprises:
When the card type optical recording medium as shown in FIG. 1 is used as a personal ID card, the authenticity of the card is authenticated and personal information can be displayed as necessary. The personal ID card 10 shown in FIG. 1 includes a data recording area 11 in which at least one different card ID (identification information) is recorded by a plurality of holograms (computer generated holograms), and a photograph of the face of the individual. A printed face photograph area 12, an information printed area 13 on which personal information such as a name is printed, and an IC module (and / or a magnetic recording area) 14 are provided as necessary.

Here, the identification information recorded in the data recording area 11 has different contents one by one, and a predetermined number of CGHs provided in the data recording area 11 when the card is created. Is recorded so that it cannot be rewritten.

FIG. 4 shows an optical recording medium (personal ID card) 1
FIG. 7 is a diagram for explaining an example of a method of recording identification information unique to each card (information capable of identifying each card) in the CGH column of the data recording area 11 when issuing 0. It is. Here, the meaning of recording information in the CGH column differs depending on the position of the destroyed CGH (or the position of the undestructed CGH) by destroying a predetermined number of CGHs included in the CGH column. It means giving meaning.

The specific position of the CGH to be destroyed is determined by the combination. Combination fracture, for example, out of 10 CGH28, when making sure to destroy five to is, as shown in FIG. 4, ₁₀ C
₅ = 252 meanings. And in this case, the CGH destroyed in any combination
And the number of non-destructive CGHs are always 5, so
If other CGHs were destroyed in an attempt to rewrite this combination for forgery, the number of non-destructive CGHs would be 5
And the data indicated by the CGH becomes meaningless. As described above, the CGH is an irreversible memory, and it is impossible to reproduce the destroyed CGH. Therefore, once information is recorded in the CGH, rewriting cannot be performed. If the same CGH information is to be reproduced, the CGH must be replicated or analyzed in some way, and the method is complicated. Therefore, recording information in this CGH column is an extremely effective means against forgery and the like.

For example, in the case of a row in which 30 CGHs are arranged (a plurality of rows may be used), ₃₀ C ₁₅ = about 1.
500 million expressions can be performed, and it becomes possible to issue a card 10 having different information for the Japanese population.
Furthermore, in the case of arranging the 50 CGH28 it is, ₅₀ C
₂₅ = approximately 126 trillion expressions are possible, and it is sufficiently possible to assign unique numbers to the cards 10 whose number is equal to or greater than the population of the world. Recording data on the CGH using a YAG laser or the like in this way is a personal ID.
Since the recording is performed before the issuance of the card 10 (at the time of manufacturing), the recording apparatus itself may be installed in a factory. Therefore, at the place where the personal ID card 10 is issued or authenticated, only the optical recording medium reproducing apparatus having only the CGH and no recording means may be installed. However,
As will be described later, a part (second recording part) for additionally recording in the data storage area 11 provided with a plurality of CGHs is prepared in advance, and when information is additionally recorded in the card issuing system 1, It is necessary to enable data recording on the CGH at the card issuer. In this case, only the read access may be permitted to the portion where the identification information is recorded (the first recording portion), and writing may not be performed.

The card authentication system 3 for authenticating such a personal ID card 10 is used in an overall system as shown in FIG. In FIG. 2, the card issuing system 1 includes a face card, name, gender, date of birth, face photo information on a card called a raw card in which identification information is already recorded in the data storage area 11 but other information is not recorded. blood type,
In addition, personal information such as a face photograph and a name are printed so as to be visually recognized. At this time,
When personal information and face image information are registered on the card issuing system 1 side, the contents are also registered in the database 2, and when personal information already registered in the database 2 is used, the card issuing system 1 is used. To receive that information. In any case, the identification information recorded in the data storage area 11 of the raw card is read by the card issuing system 1, and the identification information is transmitted to the database 2 and registered in association with the personal information.

In the authentication in the authentication system 3, the card information including the identification information is transmitted from the authentication system 3 to the database 2, and the personal information corresponding to the identification information is transmitted from the database 2 to the authentication system 3. Authentication by the authentication system 3 becomes possible. When recording all necessary personal information in the personal ID card 10,
The personal ID card 10 issued by the card issuing system 1 can be authenticated by the card authentication system 3 alone without using the database 2.

Here, FIG. 3 shows the configuration of one embodiment of the card authentication system 3 of the present invention. It is to be noted that all the components of the card authentication system 3 are not always necessary, and a necessary configuration is appropriately selected and configured according to each embodiment described below.

A CGH reproduction image is obtained and output by providing an image pickup device such as a CCD and taking an image. CGH reproduced image is image recognition means 3
2 is compared with the reproduction position information (basic position information) of the reproduced image stored in advance and the content (recognition parameter) meaning of the reproduced image, and the content is recognized.

When the CGH recognition result includes an access key (permission information) for the IC module 14, the permission information is supplied to the access code generation means 33 and the access code for the IC module 14 is supplied. (CS
C) is generated and supplied to the IC data reading means 34, and the information (card data) recorded in the IC module 14 of the personal ID card 10 is read and displayed on the display means 36.

Then, by using the identification information included in the recognition result of the CGH and the search information of the database recorded as card data in the IC module 14, D
The B reading means 35 accesses the database 2 to read the owner information (personal information) and the card identification information registered in the database 2, and the DB information collation / display means 37 reads the IC information from the IC data reading means 34. The result is displayed by comparing it with the output personal information (card data) and the CGH recognition result. The collation by the information collation / display means 37 may be a collation of only a part of the personal information.

Further, when authenticating the cardholder, the photographer captures the face of the owner from the information input means 38 such as a video camera, a digital camera, a fingerprint detection device, and a key input device, takes in a fingerprint image, and obtains a password. Input, etc.,
The image information collating and displaying means 39 collates the image with the face image, fingerprint information, personal identification number, and the like recorded in the database 2 and the IC module 14 to authenticate the owner and display. The face and fingerprint information may be compared by judging the similarity between the face and the fingerprint image itself, or by extracting the feature points of the face or the fingerprint image or comparing them with the feature points that have already been extracted and recorded. Is also good. Further, both the face from the information input means 38, the face stored with the fingerprint information, and the fingerprint information may be output to the image information collation / display means 39 so that the operator can make a judgment.

When recording the authentication history and the state of the card in the database 2 or the IC module 14, the information is written into the database 2 or the IC module 14 by the writing means 40.

Next, embodiments of the present invention will be described with reference to the drawings. In addition, FIG. 3 shall be referred to by each embodiment.

In the first embodiment described below with reference to FIGS. 3 and 5, the first embodiment is registered in the database 2 using the identification information recorded in the data recording area 11 of the personal ID card 10. This is a card authentication system for reading and displaying personal information. In this case, as shown in FIG. 5, it is sufficient that only the identification information is recorded in the data recording area 11, and the personal information is registered in the database 2 corresponding to the identification information. In addition, the personal ID card 10 without the IC module 14 or the magnetic recording area
It is also possible to use

When authenticating the personal ID card 10, the identification information obtained from the CGH reproducing means (reproducing means) 31 and the image recognizing means (reading means) 32 is used to read the DB reading means (obtaining means). ) 35 to access the database 2 to read out personal information and the like;
GH, IC, and DB
It outputs to the B information collation / display means 37. At this time, if the image recognition means 32 determines that the identification information is counterfeit or the identification information cannot be reproduced, or if there is information that does not match in the verification, the information to that effect is displayed on the DB information verification / display means 37. . The personal ID card 10 may be collected by a collecting unit (not shown) as needed.

In a second embodiment described below with reference to FIGS. 3 and 6, the data recording area 11 of the personal ID card 10 is divided into at least a first recording section and a second recording section. This is a card authentication system in which identification information is recorded in a first recording unit and personal information is recorded in a second recording unit, and information is read out from the data recording area 11 and displayed. . In this case, as shown in FIG. 6, since the identification information and the personal information are recorded in the data recording area 11, the card can be authenticated by the card authentication system alone without accessing the database 2. . Further, the personal ID card 10 without the IC module 14 or the magnetic recording area can be used.

When the personal ID card 10 is authenticated, the CGH reproduced image obtained from the CGH reproducing means 31 is supplied to the image recognizing means 32 and the identification information is judged to be valid. , The personal information obtained from the CGH reproduction image is output to the recognition result display means 36 and displayed. At this time, if it is determined by the image recognition means 32 that the proper identification information cannot be obtained or that the recognition information cannot be reproduced, information indicating that fact is displayed on the recognition result display means 36. Also in this case, the personal ID card 10 may be collected by a collecting unit (not shown) as necessary.

A third embodiment, which will be described below with reference to FIGS. 3 and 7, uses an IC using the permission information recorded in the data recording area 11 of the personal ID card 10.
Reading the identification information recorded in the module 14;
This is a card authentication system that reads and displays personal information registered in the database 2 only when the identification information matches the identification information recorded in the data recording area 11. In this case, as shown in FIG. 7, identification information and permission information are recorded in the data recording area 11, and the IC module 1
4 records identification information and database search information. In the database 2, personal information corresponding to the identification information is registered in a format that can be searched by the database search information. The IC module 14 can read and write only by using the permission information recorded in the data recording area 11.

When the personal ID card 10 is authenticated, the CGH reproducing means (reproducing means) 31 and the image recognizing means (first reading means) 32 use a data recording area (first data recording area). The permission information and the identification information recorded in 11 are read, and this permission information is supplied to the access code generation means 33 to generate an access code (CSC) for the IC module (second data recording area) 14, The identification information is supplied to the IC data reading means (second reading means) 34 and read out from the IC module 14 of the personal ID card 10.

Only when the identification information read from the data recording area 11 and the identification information read from the IC module 14 match, the DB reading means (obtaining means) 35 uses the database search information to search the database 2. To read personal information, etc.
Output to the recognition result display means 36. At this time, if the image recognition means 32 determines that the identification information is counterfeit or the recognition information cannot be reproduced, or if the identification information read from the data recording area 11 does not match the identification information read from the IC module 14, For example, the display of forgery or inaccessibility is performed by the recognition result display means 36, so that the database 2 is not accessed or transmitted to the database 2 to the effect that it is an unauthorized card. Further, the information read from the IC module 14 does not match the information registered in the database 2, or
If the identification information obtained in step 2 does not match the information registered in the database 2, information indicating that fact is displayed on the DB information collation / display means 37.

When the identification information and the personal information are recorded in the IC module 14, the card can be authenticated without using the database 2. That is,
The CGH reproducing means (reproducing means) 31 and the image recognizing means (first reading means) 32 use the data recording area (first
Of the IC module (second data recording area) 14 by reading the permission information and the identification information recorded in the data recording area (11) of the IC module (second data recording area). ), And
The IC module 14 of the personal ID card 10 supplies the IC data to the IC data reading means (second reading means) 34.
Read the identification information recorded in the.

Only when the identification information read from the data recording area 11 and the identification information read from the IC module 14 match, personal information and the like can be transferred from the IC module 14 using the IC data reading means 34. The data is read out and output to the display means 36. At this time, if the image recognition means 32 determines that the identification information is counterfeit or the recognition information cannot be reproduced, or if the identification information read from the data recording area 11 does not match the identification information read from the IC module 14, , Forgery or inaccessibility is displayed on the display means 37, and the personal information recorded in the IC module 14 is not displayed.
At this time, it may be recorded in the IC module 14 that the card is an unauthorized card.

As another method for authenticating the personal ID card 10, permission information and identification information are recorded in a data recording area (first data recording area) 11.
Only the database search information may be recorded in the C module (second data recording area) 14. In this case, the permission information and the identification information recorded in the data recording area (first data recording area) 11 are converted by the CGH reproducing means (reproducing means) 31 and the image recognizing means (first reading means) 32. The access information is supplied to the access code generation means 33, and the IC module (second
Access code (CSC) to the data recording area 14)
Is generated and supplied to IC data reading means (second reading means) 34 to read database search information recorded in the IC module 14 of the personal ID card 10. Then, using the database search information read from the IC module 14, the database 2 is accessed by the DB reading means (obtaining means) 35 to read the identification information, the personal information, etc., and the recognition result display means 3
6 for display. At this time, if the image recognition means 32 determines that the identification information is counterfeit or the recognition information cannot be reproduced, or if the identification information read from the data recording area 11 does not match the identification information read from the database, the counterfeiting is performed. Alternatively, display such as inaccessibility is performed by the DB information collating and displaying means 37, and personal information of the database is not displayed. Further, at this time, the IC module 14 may record that the card is an unauthorized card.

In each of the above embodiments,
An access information recording unit is provided in the data recording area (first data storage area) 11, the IC module (second data storage area) 14, or the database 2, and the number of times of authentication of the personal ID card 10, the authentication date and time, the authentication place, Access history information such as authentication contents may be recorded. When recording in the IC module 14 or the database 2, the writing means 37 (recording means) writes the access history information.

Further, in each of the above embodiments,
When authenticating whether the owner of the personal ID card 10 is a legitimate owner, the face or fingerprint information of the owner is input on the spot by the image information input means 38, and the database 2 or the IC module 14, A face or fingerprint information (a face or a fingerprint image, feature point data of a face or a fingerprint, etc.) which is a part of the personal information recorded in any of the data recording areas 11 is compared by the information comparing means 39, and the comparison result is obtained. Alternatively, both images may be output to the display means 39 to determine whether or not the user is the proper owner, and the personal information may be displayed only when it is confirmed that the user is the proper owner. It should be noted that the face or fingerprint information, which is a part of the personal information recorded in any one of the database 2 or the IC module 14 and the data recording area 11, is converted into an image to perform image
The information may be simply displayed on the display means 39. In this case, the operator can determine whether or not the user is an authorized owner by comparing the face or the fingerprint of the owner.

In each of the above embodiments,
Even if a magnetic recording area is provided instead of or in addition to the C module, the same can be realized. If the third embodiment is implemented as a magnetic recording area, the identification signal to be recorded in the magnetic recording area may be encrypted, and the decryption key may be recorded in the data recording area 11 as permission information.
