BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to protection of written contents of printed matter, and more particularly, to detection of falsification of recorded information,
Regarding techniques related to verification of uniqueness.

[0002]

2. Description of the Related Art Japanese Patent Application Laid-Open No. 8-297743 discloses a technique for preventing tampering of a printed material. In this publication, after reading information of a printed material and converting it to electronic information, the electronic information is compressed using a hash function or the like to create dependency information, converted to a print format such as a barcode, and converted to a printed material. A technique for creating a printed matter by adding the information is described. When verifying the printed matter, the dependency information generated by reading the information of the printed matter in the same process as above is compared with the dependent information restored by reading the barcode or the like added to the printed matter. Thus, tampering of information is detected.

[0003]

In the prior art described in the above publication, alteration of information is prevented by printing dependency information such as a bar code. However, since both the information described in the printed matter and the dependent information are print information that can be copied by a copying machine, a copy can be easily created by copying the printed matter described in the official gazette by a copying machine or the like. Therefore, it is difficult with this conventional technique to ensure the uniqueness of the printed matter. On the other hand, as a technique for ensuring the uniqueness of a printed matter, there is a technique in which a special pattern or a watermark is added to the paper used for printing so that the paper can be distinguished from the copy paper by appearance and touch. Therefore, it is conceivable to create a printed matter described in the above-mentioned publication using a special pattern or a paper with a watermark to prevent falsification of information of the printed matter and to ensure the uniqueness of the printed matter. However, in recent years, the performance of copiers has dramatically improved, and it has become possible to reproduce information on printed matter with high precision, so that it is possible to output the whole image including special patterns and watermarks. Was. Therefore, even if a printed matter described in the official gazette is created using a paper with a special pattern or a watermark, it is difficult to sufficiently ensure the uniqueness of the printed matter.

[0004] It is an object of the present invention to solve the above-mentioned problems and to provide a printed matter verification information adding technique and a printed matter verification technique which ensure the uniqueness of a printed matter and highly protect the information of the printed matter.

[0005]

In order to solve the above problems, a printed matter verification information adding apparatus according to the present invention uses an ID sheet which outputs ID information in response to a radio wave as a sheet.
The digitized data of the verification target image printed on the D paper, which is a place that needs to be verified, is encrypted using an encryption key corresponding to the ID information output from the ID paper, and the information is verified. The information is added to the ID paper as information. The printed matter verification device converts the verification target image into digitalized data in the same manner as the printed matter verification information adding device and separately obtained verification information into the I
By comparing the data decrypted with the decryption key corresponding to the b information output by the D paper, it is determined whether the two data match, and the uniqueness of the printed matter and the presence / absence of falsification of the information are verified.

In addition to the ID function, the ID device integrally attached to or incorporated in the above-described ID paper also has a function of additionally writing electronic information, and a method of additionally writing the verification information 110 on such an ID device. is there. Alternatively, a device having an additional recording function may be pasted on or built into the ID paper separately from the ID device, and the verification information 110 may be additionally recorded on this device.

The print verification information adding apparatus 5 includes:
Since the processes of the information compressor 40, the encryptor 50, and the encryption key generator 70 are numerical operations, they can be implemented by software. Further, the information compressor 40, the encryption device 50, and the encryption key generation device 70 may be configured as an information processing device 80 and may be constituted by independent devices, or the information compression device 40, the encryption device 5

Also, the encoder 90 can be implemented by software, and may be included in the information processing apparatus 80 described above, or may be an independent apparatus, or may be an apparatus integrated with the code generator 100. There may be.

In this embodiment, the printed matter verification information adding device 5 does not need to be a physically integrated device.
For example, the image scanner 20 and the A / D converter 30 are scanners, the ID scanner 60 is an ID reader, the information processing device 80 and the encoder 90 are computers, and the code generator 100 is a printer. It may be operated. Here, the ID reader is a device that applies a specific radio wave to the ID paper and acquires ID information output from the ID paper in response to the radio wave. When the image to be verified is character information, the image scanner 20 and the A / D converter 30 are OC
R can also be used. When the verification information 110 is a barcode, a barcode printer can be used as the encoder 90 and the code generator 100. In such a configuration, a program for performing each of the above operations is installed in the computer.
This program is recorded on a computer-readable recording medium or provided through a communication line. In the embodiment described later, the printed matter verification information adding device 5 does not need to be integrated, and may be constituted by a scanner, an ID reader, a computer, a printer, and the like. Further, in order to maintain the security of the process of adding the verification information 110, the printed matter verification information adding device 5 is installed in a safe place with a low risk such as reverse engineering, and only the printed matter verification device 300 described later is used for the printed matter. It can be placed wherever verification is required.

FIG. 2 shows a first embodiment of a printed matter verification apparatus according to the present invention.
FIG. 2 is a block diagram showing an embodiment of the present invention, and ID paper 10 with verification information 110 added by the printed matter verification information adding device 5 of FIG.
1 shows a configuration of a printed matter verification device 300 that performs verification of a printed matter. Hereinafter, the operation of the printed matter verification device 300 will be described. The image scanning device 210 serving as an image scanning unit includes the verification information 110.
An image to be verified, which is a place that needs to be verified, is read out of the images printed on the attached ID paper 10, and this information is converted into bitmap information by an A / D converter 220, which is an inspection target information generating unit. The information compressor 230 compresses information necessary for verification from the bitmap information. In the process from image scanning to compression, conversion equivalent to the flow of data from the image scanner 20 to the information compressor 40 of the printed matter verification information adding device 5 is performed. At the same time, the ID scanner 260 as the ID information acquisition unit reads the ID information 65 of the ID paper 10 and inputs the ID information 65 to the decryption key generator 270 as the decryption key generation unit. The decryption key generation device 270 stores the ID of the ID paper 10
It has a pair of the information 65 and the decryption key 275 and gives the decryption key 275 corresponding to the ID information 65 to the decryption device 250. Note that the decryption key generator 270 may generate the decryption key 275 by calculating based on the ID information 65.

A verification information reader 240 as verification information reading means reads the verification information 110 of the ID sheet 10. The verification information 110 is converted into numerical data by the digitizer 245. This conversion is performed by the printed matter verification information adding device 5.
Is the inverse transform of the encoder 90 of FIG. This numerical value is provided as an input to the decryptor 250 and decrypted using the decryption key 275.

The pair of the ID paper ID information 65 and the encryption key 75 of the encryption key generator 70 of the print verification information adding apparatus 5 is the ID information 65 of the ID paper 10 of the decryption key generator 270 of the print verification apparatus 300. And the pair of the decryption key 275 and the algorithm of the decryptor 250 and the decryption key 2
The combination of 75 is complementary to the above-described combination of the encryption algorithm of the encryption device 50 and the encryption key 75 of the printed matter verification information adding device 5. Therefore, the information encrypted by the encryption device 50 using the encryption key 75 can be decrypted by the decryption device 250 using the decryption key 275, and the original information can be restored.

With the above features, the verification information is read, digitized, and decrypted in the print verification apparatus 300 so that the output of the decryption apparatus 250 is the same information as the input of the encryption apparatus 50 of the print verification information adding apparatus 5. Is performed. Output 255 of the decoder (hereinafter referred to as “decryption verification information”)
Is compressed information required for verification at the time of adding the verification information 110 to the ID paper 10. On the other hand, the information 235 output from the information compressor 230 of the printed matter verification apparatus 300.
(Hereinafter referred to as “verified information”) is the current ID paper 10
This is equivalent to performing processing from the image scanner 20 of the printed matter verification information adding device 5 to the information compressor 40 on the print information held by the printer. The information and the information under verification should match.

The comparator 280, which is a determining means, compares the decryption verification information 255 with the verification target information 235, and if they match, adds the verification information 110 to the print information of the current ID paper 10. If the information at the time is maintained, and if they do not match, it is determined that the information at the time when the current ID paper 10 has added the verification information 110 is not maintained, and as a result 31
Outputs 0. As a method of outputting, the result 310
Any method may be used as long as the method can notify the user of the printed matter. For example, there is a method of providing a display unit in the printed matter verification device 300 and displaying the result. Also, instead of or in addition to the result of the match, the contents of the decryption verification information 255 and the verified information 235 itself may be output.

As described above, the printed matter verification device 300 scans the ID sheet 10 to which the verification information 110 is added with the same contents as the printed matter verification information adding device 5, performs A / D conversion,
The information to be verified is generated by performing information compression, and the verification information 11 added by the printed matter verification information adding device 5 is output.
From 0, decoding verification information is generated by restoring the results of image scanning, A / D conversion, and information compression at the time of adding the information, and by comparing the two, it is confirmed whether or not the information has been tampered with. can do. Also, at the time of this restoration, by utilizing the ID function of the ID paper 10,
If the printed matter is a duplicate, the same procedure cannot be performed, and the uniqueness of the ID paper 10 can be ensured.

The processing of the information compressor 230, the digitizer 245, the decryptor 250, the decryption key generator 270, and the comparator 280 of the printed matter verification apparatus 300 is a numerical operation, and is therefore implemented by software. be able to. These are included in the information processing device 290, and the information processing device 29
0 may be an independent device, or the information compressor 230, the digitizer 245, the decryptor 250, the decryption key generator 270,
Each of the comparators 280 can be configured as an independent device.

As described with reference to FIG. 1, the image scanner 210 and the A / D converter 220, the verification information reader 240 is a scanner, and the ID scanner 260 is an ID reader.
The information processing device 290 may be operated as a computer by connecting them. When the verification target image or the verification information is character information, OCR can be used. When the verification information is a barcode, a barcode scanner may be used. In such a configuration, a program for performing each of the above operations is installed in the computer. This program is also recorded on a computer-readable recording medium or provided using a communication line. In the embodiment described below, the printed matter verification device 300 does not need to be integrated, and may be configured by a scanner, an ID reader, and a computer.

As described above, since the ID information 65 output from the ID paper 10 is not copied by a normal optical copying apparatus, the uniqueness of the printed matter 10 can be ensured by this ID function. That is, when the printed matter 10 is copied, when the printed matter is verified using the printed matter verification device 300, the ID information 65 output from the copied matter is different from the ID information 65 of the genuine printed matter, so that the printed matter 10 is decrypted. If the verification information 255 is not correctly generated and compared with the verification information 235 separately generated from the verification target image, the two are determined to be inconsistent, and it is easily detected that the data is a duplicate.

Further, by adding the verification information 110 generated from the verification target image to the printed matter 10, the printed matter 1
0 can be prevented from being falsified. That is, the printed matter 10
If the verification target image printed on
Since the verification target image of the falsified printed material is different from the original verification target image, the verification target information 235 is not correctly generated, and if the verification target information 235 is compared with the decryption verification information 255 separately generated from the verification information 110, the both are determined. Are determined to be mismatched, and it is easily detected that the printed matter is a falsified printed matter. Also, it is impossible to falsify the printed matter 10 in correspondence with the verification target image up to the verification information 110 unless the encryption key 75 corresponding to the ID information 65 output from the ID paper 10 is used. By safely managing the information 75, it is possible to prevent the tampering of the printed matter 10 more strongly.

In order to improve security, the encryption key 75
For example, as described above, the printed matter verification information adding device 5 may be installed in a safe place. As will be described later, a method of separately managing the management of the encryption key 75 and the decryption key 275, the printed matter verification information adding device 5, and the printed matter verification device 300 and using communication may be employed.

Reference numeral 80a denotes an information processing apparatus in which the encryption generator 70 is separated. Other configurations are the same as those in FIG. 1, and the same components are denoted by the same reference numerals and description thereof will be omitted.

In this embodiment, the ID information 65 read by the ID scanner 60 is transmitted to the encryption key generator 70 via the communication path 120 using a communication means (not shown). The key management center provided with the encryption key generator 70 receives the transmitted ID information 65 by receiving means (not shown), and uses the encryption key generator 70 to generate the encryption key in the same manner as described in FIG. 75 is transmitted to the printed matter verification information adding device 5a via the communication path 120 using a transmission unit (not shown). The printed matter verification information adding device 5a encrypts the compressed data obtained from the verification target image using the encryption key 75 received by the communication unit (not shown). In this embodiment,

Other configurations are the same as those in FIG. 2, and the same components are denoted by the same reference numerals and description thereof will be omitted.

In this embodiment, the ID information 65 read by the ID scanner 260 is transmitted to the decryption key generator 270 via the communication path 120 using a communication means (not shown). The key management center provided with the decryption key generator 270 receives the transmitted ID information 65 by receiving means (not shown).
The decryption key generator 270 generates a decryption key in the same manner as described with reference to FIG. 2, and transmits the decryption key to the print verification apparatus 300a via the communication path 120 by a transmission unit (not shown). The printed matter verification device 300a decrypts the verification information using the received decryption key. In this embodiment, the decryption key 27
5 is performed not in the printed matter verification apparatus 300a but in a secure place for key management and the like.

It has been described that 0 is provided in the key management center. The key management center manages the keys in an effort to ensure security. When the ID information 65 is transmitted from the printed matter verification information adding device 5a, the key management center replaces the encryption key 75 corresponding to the ID information 65 with the printed matter verification device. When the ID information 65 is transmitted from the terminal 300a, this system is managed by an organization whose business is to return the decryption key 275 corresponding to the ID information 65. According to the configurations shown in FIGS. 3 and 4, only the ID information 65 is transmitted without transmitting the contents of the printed matter to be verified, so that the user can know the contents of the printed matter to a third party who manages the center or the like.

According to this embodiment, since the encryption key 75 is generated not in the ID paper printing device 6 but in a secure place where the key is managed, the relationship between the ID information 65 and the encryption key 75 is hidden. High security can be secured. In the case of the configuration shown in FIG. 8, one encryption key generator 70 is prepared and a plurality of IDs are prepared.
An implementation is possible in which the paper printing device 6 is connected to the encryption key generator 70 by communication.

FIG. 9 is a block diagram showing one embodiment of an ID paper printing apparatus and a print content creation center with verification information according to the present invention. In addition to the configuration shown in FIG. 2 shows a configuration in the case where the processing is performed outside the paper printing apparatus 6. The difference from FIG. 8 is that the print content creator 15a for creating print content is divided into two, and the first print content creator 15a for creating information 104 that does not need to be verified is provided inside the ID paper printing device 6. The second print content creator 15b that creates the information 35 to be verified and placed is placed in a print content creation center with verification information installed outside the ID paper printing device 6b, and the information 35 to be verified is transmitted to the communication means ( (Not shown) using communication channel 1
20 to the printing machine 105 and the encryption machine 5
0 and the encoder 90 are also placed at the print content creation center with verification information. That is, the main information processing device 80c is located at the print content creation center with verification information. Other configurations are the same as those in FIG.

The printing machine 105 includes a first printing content creating machine 1
5a, the information 104 that does not need to be verified and the second
To be verified 35 created by the print content creating machine 15b
Then, the information 35 to be verified is encrypted by the encryption device 50 and the three types of verification information 110 encoded by the encoder 90 are combined and printed. In the case of such a configuration, since the second print content creator 15b, the encryption key generator 70, the encryptor 50, and the encoder 90 are respectively numerical processing, they can be included in the information processing device 80. is there. Further, although not explicitly shown in FIG. 9, the ID paper printing device 6b shown in FIG.
It is also possible to eliminate the information creation function that does not need to be verified by the print content creator 15a, and to make the second print content creator 15b of the information processing device 80 create all print content.

As described above, the embodiments of the printed matter verification information adding device 5, the printed matter verification device 300, and the ID paper printing device 6 have been described with reference to FIGS. 1 to 9. In each embodiment, the encryption algorithm is as follows. There is no particular limitation, and any encryption algorithm can be implemented.

To enhance the security, the RSA encryption algorithm is optimal, and the ID paper 1 of the encryption key generator 70 is used.
0, a pair of the ID information 65 and the encryption key 75, and the ID information 65 and the decryption key 275 of the ID paper 10 of the decryption key generator 270.
And the encryption key 75 and the decryption key 275 associated with the same ID information 65 have a relationship between a secret key and a public key in the RSA encryption method. Then, the printed matter verification information adding apparatuses 5, 5a, 5b are installed in a highly secure place, the encryption key 75 is used as a secret key, and the decryption key 275 used in the printed matter verification apparatuses 300, 300a, 300b is used as a public key. . If the secret key and the public key are used in this way, the key information used for encryption when the verification information is added and the key information used for decryption during the verification will be different. Even if it is used, the decryption key 2
Since it is not possible to know the encryption key 75 from 75, it is difficult to create a fake of the printed matter verification information adding device 5, 5a, 5b or the ID paper printing device 6, 6a, 6b.
Therefore, since the verification information 110 cannot be generated, it is possible to prevent falsification of the printed matter. Further, if the decryption key 275 used in the printed matter verification devices 300, 300a, and 300b is made public as a public key, general users can perform verification, which is convenient.

In order to enhance security, the encryption key 75
It is also effective to limit the number of generations of For example, if the generation of the encryption key is limited to one time, once the verification information 110 is added to the printed matter, the encryption key 75 will not be generated again, so that the verification information 110 can be added after the second time. And falsification can be prevented.

In each of the embodiments, the information compressor is used. However, the information compressor is unnecessary when the information does not need to be compressed. When the information to be verified is a character, the technology of character recognition is particularly effective.

In the embodiment using the communication path 120, if a communication control unit having encryption and decryption functions is installed before and after the transmission and reception of information, the security is further improved. The communication path 120 may be a dedicated line,
Alternatively, a network such as the Internet may be used. Also, each center described in each embodiment can use a server connected to a dedicated line or a network.
