Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an authentication record such as a personal authentication card or a credit card provided with an authentication image such as a face image or a tint block image, and
The present invention relates to an authentication method, an authentication device, and an authentication system for determining the authenticity of a user and a user of the authentication record.

[0002]

2. Description of the Related Art In recent years, systems using cards, such as shopping using an after-paid card such as a credit card, withdrawal of a deposit using a bank card, and a prepaid card in a transportation system, have become widespread in society. In the future, it is expected that a system that can use a plurality of systems with one card will be developed.

In such a system, when a card which is a key for use of the system is forged, or when a card holder is falsified by a card holder, the card holder is falsified and illegally used. Significant damage can occur to system builders or legitimate cardholders. Alternatively, if a record for authentication such as a passport or a driver's license issued by a public organization is forged or its contents are falsified, there is a concern that it may become a serious social problem.

[0004] As described above, security is required for an authentication record to be used. In order to prevent counterfeiting of the record for authentication, a face image of the owner (user),
Alternatively, a special sheet, such as a hologram sheet having a specific pattern, which is generally difficult to obtain, is provided for authentication.
In addition, a background pattern with a specific pattern is provided, or an image with a special printing technique is provided for authentication.

Further, when the system is used by using the authentication record, the owner of the authentication record and the user are generally stored in advance in the authentication record in order to check whether or not the owner and the user are the same person. The authenticated number is collated with the authentication number input by the user to the terminal device of the system to determine the authenticity of the user.

However, if such information is falsified, unauthorized use becomes possible. In addition, the alteration of information includes alteration of the balance of a prepaid card. In order to prevent the information stored on the card from being tampered, security is improved by using a special magnetic recording for the magnetic card or by using an IC memory (such as an IC card) for which the information storage section is more difficult to falsify than the magnetic recording. It is intended to be improved.

[0007]

However, in response to these measures, the face image is replaced, the special sheet is diverted,
The copying of special prints by computers, color scanners, and color printers with high performance is performed, and therefore, the countermeasures described above are not always thorough with respect to forgery of authentication recordings.

[0008] In recent years, with respect to falsification of information stored in authentication recordings, computer performance has been improved,
If a person with specialized knowledge, such as the emergence of advanced information analysis software, makes full use of knowledge and equipment, it is expected that reading and writing of information in an IC memory will be possible in the near future.

For example, even if the authentication image is changed from the face image of the authorized owner to the face image of the unauthorized user, the face of the unauthorized user matches the face image of the authentication record.
There is a risk that unauthorized use of the authentication record may not be recognized.

Accordingly, an object of the present invention is to provide an authentication record which is resistant to forgery, falsification, or alteration of stored information due to replacement of an authentication image.

Further, the present invention provides an authentication method, an authentication apparatus, and an authentication system which can determine the authenticity of an authentication record even if the authentication image or the like of the authentication record is forged or falsified. The purpose is to:

Further, the present invention provides an authentication method capable of determining the authenticity of a proper owner and a user of an authentication record even if the authentication image or the like of the record for authentication is forged or falsified.

[0018]

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

FIG. 1 is a personal authentication card (certificate IC card) as an authentication record according to an embodiment of the present invention.
Is schematically shown. In FIG. 1, on one side (front side) of the personal authentication card C, a face image section 1 on which a face image of a card owner, which is an authentication image, is printed and recorded, a name 2 of the card owner, and a card An expiration date 3 and the like are provided. On the other surface (back surface) of the personal authentication card C, a contact (contact part) 4 for obtaining electrical contact with a card reader / writer (not shown), a card issuing company name 5, and the like are provided. .

An IC memory (integrated circuit memory) 6 as an information storage unit is embedded in the personal authentication card C, and the IC memory 6 is electrically connected to the contact 4.

In a part of the face image unit 1, fingerprint information as biometric information for identifying a person of the face image converted into barcode information is recognized as a pattern which is difficult to recognize visually and can be recognized through a reproduction filter described later. An embedded image section 7 superimposed and recorded on the face image section 1 is provided.

The authentication image may be, for example, a specific background pattern, a logo mark,
Images, characters, and patterns that characterize the authentication record, such as the name of the authentication record issuer, can be used.

Also, biometric information for specifying a person includes:
In addition to the above fingerprint information, such as the iris, the positional relationship between the eyes and the nose,
Information unique to a human individual can be used.

The pattern of the fingerprint information recorded in the embedded image section 7 includes, for example, a first grid 10 indicated by an upward arrow (↑) and a downward arrow (↓), as schematically shown in FIG. And a color-difference grating pattern composed of a combination with the second grating 11 indicated by.

FIGS. 3A and 3B show the first grating 10 and the second grating 11 in detail, each of which is divided into an upper half and a lower half. In the first lattice 10 shown in FIG. 3A, the upper half is configured such that the blue component is added to the face image portion 1 and the red component is reduced by that amount so that there is no change in brightness. On the contrary, the red component is added to the face image portion 1, and the blue component is reduced by that amount.

In the second grid 11 shown in FIG. 3 (b), the red color component in the upper half of the face image portion 1 is opposite to the first grid 10.
And the blue component is reduced by that amount so that there is no change in brightness. In the lower half, on the contrary, the blue component is added to the face image portion 1 and the red component is reduced by that amount. These first and second gratings 10 and 11 are called a color difference grating pattern.

Next, the issuing process of the personal authentication card C will be described. FIG. 4 schematically shows a configuration of a card issuing device for performing an issuing process. This card issuing device includes an image output unit 40, a fingerprint information generation unit 41, a barcode generation unit 42, a color difference grid modulation unit 43, an adder 44, a face image unit printing unit 45, a coding processing unit 46, and an IC memory. The writing unit 47 is configured.

First, a process for providing a face image portion on which fingerprint information is superimposed and recorded will be described with reference to a flowchart shown in FIG. The fingerprint information generation unit 41 generates the fingerprint information of the index finger, which is the biometric information of the person registered in the personal authentication card C registered in advance (S1),
The data is input to the barcode generator 42. The barcode generation unit 42 converts the input fingerprint information into barcode information (S2), and outputs it to the color difference grid modulation unit 43.

The chrominance grating modulating section 43 is provided in FIG.
The first grating 10 and the second grating 11 shown in (b) are read (S3), and the color difference grating pattern is modulated by the barcode information from the barcode generator 42 (S4).

That is, the color components forming the face image of the face image section 1 are cyan, magenta, and yellow, and the color component amount signals Co (cyan), Mo that specify the amounts of these color components.
(Magenta) and Yo (yellow), the first and second lattices 10 and 11 each have ± αc in accordance with the following formula according to the pattern information of the embedded image portion 7 with respect to the face image portion 1. , ± αm, ± αy are added to modulate the color difference grid pattern.

C ′ = Mo ± αc M ′ = Mo ± αm Y ′ = Yo ± αy However, by adding ± αc, ± αm, ± αy, luminance I = (± αc) + (± αm) + (± αy) does not change,
It is desirable that only the color difference be changed. Also,
The first grating 10 and the second grating 11 are configured such that there is no difference in the average chromaticity (the average chromaticity of the upper half and the lower half), that is, the first grating 10 and the second grating 11 Are set to be approximately “0”. α
The plus or minus sign added before c, αm, and αy is selected according to the pattern to be superimposed and recorded.

In this manner, the color difference grid pattern is modulated by the pattern information corresponding to the fingerprint information (S
4) The modulated color difference grid pattern is input to the adder 44. Also, from the image output unit 40, color component amount signals Co (cyan), Mo (magenta),
Yo (Yellow) is output (S5) and input to the adder 44.

The adder 44 converts the modulated color difference grid pattern from the color difference grid modulator 43 into the original color component amount signals Co,
Mo and Yo (S6) to generate the color component amount signals (each color recording information) C ', M' and Y 'shown in the above equation (S6).
7) Output to the face image section printing section 45. The face image section printing section 45 prints and records the face image of the face image section 1 according to the recording information, and superimposes and records the pattern of the fingerprint information converted into barcode information on the embedded image section 7 (S8). .

As described above, the addition of ± αc, ± αm, ± αy causes no or small change in luminance in the grid, and the color difference between the first and second grids 10 and 11 is substantially “ Since it is set to be “0”, the grid and the image in the embedded image section 7 are hardly visible.

Next, the IC memory 6 of the personal authentication card C
The process of writing fingerprint information to the printer will be described with reference to the flowchart shown in FIG. The fingerprint information described above is output from the fingerprint information generation unit 41 to the coding processing unit 46. The coding processing unit 46 converts the fingerprint information into code information by a predetermined process (S9), and outputs the coded fingerprint information to the IC memory writing unit 47. The IC memory writing unit 47 writes and stores the coded fingerprint information into the IC memory 6 via the contact 4 of the personal authentication card C (S10).

As described above, on the face image as the authentication image, the fingerprint information of the index finger, which is the predetermined biometric information, is a pattern that is difficult to visually recognize and can be recognized by a specific method. Superimposed and recorded as
In addition, a personal authentication card in which the same fingerprint information is stored in the IC memory is obtained.

Next, a description will be given of the reproduction of the image of the embedded image portion 7 which is superimposed and recorded. By superimposing, for example, a reproduction filter 60 as shown in FIG. 6 on the superimposed recorded image, the embedded image can be recognized.

The reproduction filter 60 shown in FIG.
As in the case of the first grating 10 shown in (a), the upper half is constituted by a color difference lattice filter in which lattices of a blue filter and a lower half are arranged in a matrix of red filters. FIG. 7 schematically shows a state in which the embedded image section 7 is observed through the reproduction filter 60. When the reproduction filter 60 is superimposed on the embedded image part 7, the pixels 70 corresponding to the barcode information part of the embedded image part 7 are composed of the first grid 10, so that the pixels 70 The red filters overlap, and the brightness of blue and red becomes double overlapped.

On the other hand, since the pixel 71 corresponding to the background portion of the embedded image portion 7 is constituted by the second grid 11,
The red filter overlaps the portion where the blue component is added, and the blue filter overlaps the portion where the red component is added, which is darker than the barcode information section. As a result, the difference in brightness between the barcode information portion and the background portion makes it possible to see the barcode information as the biometric information that is superimposed and recorded.

As the reproduction filter 60, FIG.
A grating filter composed of the second grating 11 shown in (b) may be used. In this case, the barcode information portion is darker, and the background portion is brighter, and the barcode information portion can be visually recognized similarly.

Next, an authentication device for determining the authenticity of the personal authentication card C and its user will be described.

FIG. 8 shows information obtained by mechanically reading the fingerprint information of the embedded image section 7 superimposed and recorded on the face image section 1 by a specific method, code information of the fingerprint information read from the IC memory 6, and 1 schematically shows the configuration of a personal authentication card C and an authentication device that determines the authenticity of the user using fingerprint information obtained from a card user. This authentication device includes red light emitting diodes 81 and 82, optical sensors 83 and 8
4. Reproduction masks 85 and 86, embedded image extraction unit 87, coding processing unit 88, information determination unit 100, contact terminal 10
2. IC memory information reading unit 103, fingerprint information reading terminal 1
04, a fingerprint information reading control unit 105, and a display 106.

First, reproduction of fingerprint information embedded in the embedded image section 7 will be described with reference to the flowchart shown in FIG. The personal authentication card C in which the fingerprint information described above is stored in the embedded image section 7 of the face image section 1 and the IC memory 6 is inserted into the apparatus. The inserted personal authentication card C is transported by a transport path (not shown). At this time, the face image portion 1 of the personal authentication card C is illuminated by the red light emitting diodes 81 and 82 (S11), and its reflection is performed. Light is detected by the optical sensors 83 and 84.

At this time, the red light emitting diodes 81 and 82
3 in the optical axis of FIG.
Reproduction masks 85 and 86 for selecting the gratings 10 and 11 shown in (a) and (b) are provided. FIG.
10A and 10B schematically show an example of the reproduction masks 85 and 86. FIG. 10A shows the reproduction mask 85, and FIG. 10B shows the mask 86. , Hatched portions are light-shielding portions.

When the embedded image portion 7 in the face image portion 1 passes below the reproduction mask 85, a portion corresponding to the upper half of the lattices 10, 11 of the embedded image portion 7 is selectively read (S12). When passing below the reproduction mask 86, a portion corresponding to the lower half of the lattices 10, 11 of the embedded image portion 7 is selectively read (S13).

The first part of the embedded image part 7 shown in FIG.
Considering the case where only the blue / red pattern portion where blue is added to the upper half and red is added to the lower half is read out of the lattice 10 pattern, the output of the optical sensor 83 via the reproduction mask 85 is Since the blue pattern receives the reflected light illuminated with red light, the value becomes small (S14).
Next, when the same blue / red pattern is read through the reproduction mask 86, the reflected light of the red pattern illuminated with the red light is read, so that the output of the optical sensor 84 has a large value (S15).

On the other hand, in the embedded image section 7, FIG.
Considering the case where only the red / blue pattern portion where the upper half is added with red and the lower half is added with blue is read out, the pattern of the second lattice 11 is reversed. The output of the optical sensor 83 via the mask 85 has a large value (S14). Next, when the same blue / red pattern is read through the reproduction mask 86, the light sensor 8
4 has a small value (S15).

The embedding image extracting section 87 compares the output of the optical sensors 83 and 84 with respect to the same input portion to determine the pattern to be read by the embedding image section 7 in FIG.
Whether the pattern is the blue / red pattern in (a) or the red / blue pattern in FIG. 3B is identified (S16), and the embedded barcode information is extracted (S17). The extracted barcode information is sent to the coding processing unit 88. The coding processing unit 88 obtains the code information of the reproduced fingerprint information obtained from the embedded image unit 7 by converting the input barcode information into predetermined code information (S18). The code information thus obtained is stored in the information determination unit 100.
Sent to

If no information is reproduced in the process of reproducing the fingerprint information from the embedded image section 7, code information indicating "no information" is sent to the information determination section 100. In this case, the information determination unit 100 determines that the personal authentication card C is suspect.

Next, the IC memory 6 of the personal authentication card C
Will be described with reference to the flowchart shown in FIG. When the reproduction process of the fingerprint information embedded in the embedded image section 7 is completed, the personal authentication card C is set at a predetermined position.
Then, the contact 4 of the personal authentication card C comes into contact with the contact terminal 102 of the IC memory information reading unit 103 (S2).
1). As a result, the IC memory information reading unit 103
The code information of the fingerprint information is selectively read from the C memory 6 (S22), the read code information is converted into predetermined code information (S23), and the converted code information is determined by the information determining unit 1.
Output to 00.

Next, a process for obtaining fingerprint information from the user of the personal authentication card C will be described with reference to the flowchart shown in FIG.

There are several known methods for obtaining fingerprint information. Here, an electrical measurement method is used, and the method will be described below. As shown in FIG. 13, the user's index finger 13 is placed on the fingerprint information reading terminal 104.
Place 2 so that its abdomen touches. Fingerprint information reading terminal 1
In FIG. 4, a large number of rod-shaped electrodes 131 are arranged in parallel at a high density on the surface in contact with the finger 132 as shown in the figure.
Many electrodes 131 are connected to the fingerprint information reading control unit 105.

A large number of electrodes 131 are paired with adjacent electrodes, and a predetermined voltage is applied from the fingerprint information reading control unit 105. A voltage drop occurs due to the resistance of an object existing between the electrodes 131, and the voltage measured at both ends of a reference resistor (not shown) connected in series to the electrodes 131 is (applied voltage-drop voltage). When the fingerprint groove 133 of the finger 132 exists between the electrodes 131, the resistance value becomes extremely high, and the measured voltage becomes small. That is, the finger 13
A change in the measured voltage value between the pair of electrodes 131 according to the position of the second groove 133 is obtained. This change in voltage value becomes fingerprint information.

The user places the index finger 132 on the fingerprint information reading terminal 104 (S31). Then, the fingerprint information reading control unit 105 acquires voltage value information corresponding to the fingerprint information by the above-described operation (S32). Then, the fingerprint information reading control unit 105 digitizes the acquired voltage value information and converts it into binary fingerprint information (S33), and then converts it into predetermined code information (S34). The converted code information is sent to information determining section 100.

Next, the processing for determining the authenticity of the user of the personal authentication card C based on the fingerprint information obtained as described above will be described with reference to the flowchart shown in FIG. The information determination unit 100 first compares and matches the fingerprint information reproduced from the embedded image unit 7 with the fingerprint information reproduced from the IC memory 6 of the personal authentication card C (S41). In this case, permission is displayed on the display 106 (S42), and if they do not match, the fact that there is doubt about the personal authentication card C is displayed on the display 106 (S43).

If the collation results in step S41, the information determination unit 100 further performs comparison and collation with fingerprint information obtained from the user (S4).
4) If the collation result is a match, the display 106
Is displayed (S45), and if they do not match, a message that the user is suspect is displayed on the display 106 (S46).

Next, an authentication system for determining the authenticity of the personal authentication card C and its user will be described.

FIG. 15 schematically shows the configuration of an authentication system using fingerprint information as biometric information. The authentication system includes a fingerprint information registration unit 150 for acquiring and registering fingerprint information for specifying the owner of the personal authentication card C, and the fingerprint information registered by the fingerprint information registration unit 150 in the IC memory of the personal authentication card C. 6 and a personal authentication card C printed with a synthetic authentication image embedded in the face image portion 1 as a pattern that is difficult to visually recognize the same fingerprint information and that can be recognized by a specified specific method. Card issuing means 151 for issuing, fingerprint information reading means 152 for reproducing (reading) fingerprint information stored from IC memory 6 of personal authentication card C, fingerprint information embedded from composite authentication image of personal authentication card C Information reproducing means 153 for restoring and reproducing fingerprints, fingerprint information obtaining means 154 for obtaining fingerprint information from the user of the personal authentication card C, and each obtained finger. Authenticity determination unit 15 for performing authenticity determination from the information
5 and a true / false presentation means 156 for presenting the determination result (true / false).

Here, the acquisition and registration processing of the fingerprint information in the fingerprint information registration means 150 will be described with reference to FIGS.
This will be described with reference to the flowchart shown in FIG. Note that the method of acquiring fingerprint information is the same as the method described above with reference to FIG. 13, and thus a detailed description will be omitted.

First, the registrant places his / her index finger 132 on the fingerprint information reading terminal 104 (S5).
1) The voltage value information corresponding to the fingerprint information is obtained (S5).
2). Next, the obtained voltage value information is digitized and then converted into binary fingerprint information (S53). Next, this binarized fingerprint information is stored (registered) in the memory of the system (not shown) as the acquired fingerprint information (S
54). From the fingerprint information registered in the memory, desired fingerprint information is selected when the card issuance by the card issuing means 151 is stored in the IC memory 6.

The processing of the card issuing means 151 is the processing described with reference to FIGS. 4 and 5, the processing of the fingerprint information reading means 152 is the processing described with reference to FIG. The processing of the means 153 is the processing described above with reference to FIG. 9, the processing of the fingerprint information obtaining means 154 is the processing described with reference to FIG. 12, and the processing of the true / false judgment means 155 and the true / false presentation means 156. Are the same as the processes described above with reference to FIG. 14, respectively, and thus description thereof will be omitted.

As described above, according to the above embodiment, the fingerprint information of the forefinger, which is the predetermined biometric information, is difficult to visually recognize on the face image as the authentication image, and it is difficult to recognize the fingerprint information. A personal authentication card in which the same fingerprint information is superimposed and recorded as a pattern recognizable by the specified method and the same fingerprint information is stored in the IC memory is obtained.

Therefore, it is possible to obtain a personal authentication card which is resistant to forgery or falsification due to replacement of a face image as an authentication image or falsification of information stored in an IC memory.

Further, even when the face image as the authentication image is falsified, the authenticity of the personal authentication card can be determined by the presence or absence of an embedded image that cannot be visually recognized in a normal state. Further, since the fingerprint information of the user is used for the authenticity of the user, it is not possible to forge the collation information in comparison with the conventional collation using a password. For this reason, the authenticity determination of the user of the personal authentication card is ensured.

In the above-described embodiment, an IC card type personal authentication card having an IC memory as an information storage unit has been described as an example. However, a magnetic card type personal authentication card having a magnetic recording unit as an information storage unit has been described. It goes without saying that the present invention is applied to a card.

Further, the present invention is not limited to the personal authentication card, but can be similarly applied to authentication recordings such as credit cards and bank cards.

[0067]

As described above in detail, according to the present invention, it is possible to provide an authentication record which is resistant to forgery, falsification, or alteration of stored information due to replacement of an authentication image.

Further, according to the present invention, there is provided an authentication method, an authentication apparatus, and an authentication system which can determine the authenticity of an authentication record even if the authentication image of the authentication record is forged or falsified. Can be provided.

Further, according to the present invention, even if the authentication image or the like of the authentication recording is forged or falsified, the authenticity of the authenticated owner of the authentication recording and the user can be determined. An authentication method, an authentication device, and an authentication system can be provided.
