  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

(1) Identification Method As shown in FIG. 1, paper has a unique pattern (hereinafter referred to as a pattern) configured by complex entanglement of fibers inside, not the surface. As can be seen from the fact that the image can be viewed by holding it over light, it can be obtained as an image (hereinafter referred to as a pattern image) by, for example, a transmissive scanner.

  Therefore, in the identification method according to the present embodiment, as shown in FIG. 2, a predesignated area (hereinafter, designated area) of the pattern image of the original paper (hereinafter referred to as original paper) OP1 is used. A paper pattern feature amount MP1 indicating the feature of the pattern pattern is extracted from a pattern (hereinafter referred to as a pattern pattern) of the pattern image in AR1.

  Further, in the identification method according to the present embodiment, based on the print content SP1 to be printed on the original paper OP1, information representing the print content (hereinafter referred to as print content certification information) SP2 is generated. .

  Then, the identification device generates composite information MX1 by combining the paper pattern feature amount MP1 and the print content certification information SP2, and uses the composite information MX1 as an authentication code BC1 including a two-dimensional bar code on the paper surface of the original paper OP1. Print on a part of.

  On the other hand, as shown in FIG. 2B, when the identification device 1 identifies the photographic paper XPc1 on which the authentication code BC1 is printed (hereinafter referred to as “code-added photographic paper”), the code-added photographic paper The restored paper pattern feature amount MP1 ′ is extracted from the restored composite information MX1 ′ restored based on the authentication code BC1 of XPc1, and the extracted restored paper pattern feature amount MP1 ′ and the paper extracted from the pattern image in the designated area AR1. The originality (presence / absence of the original paper OP1) of the code-added photographic paper XPc1 is identified by collating it with a pattern feature amount (hereinafter referred to as a comparison sheet pattern feature amount) MP2.

  Further, the identification apparatus 1 extracts the restored print content certification information SP2 ′ from the restored composite information MX1 ′, displays the restored print content certification information SP2 ′ on a display unit or the like, for example, and displays the restored print content certification information SP2 ′. And the print content SP1 are directly visually compared with each other so that the presence or absence of alteration of the print content SP1 of the code-added photographic paper XPc1 is identified.

  Therefore, as shown in FIG. 3, even if the code-added photographic paper XPc2 is copied from the code-added photographic paper XPc1 by a copying apparatus such as a copier, for example, the code-added photographic paper XPc2 has the original paper OP1. Since the same pattern pattern existing in the designated area AR1 cannot exist, the comparison result between the comparison sheet pattern feature amount MP2 and the restored sheet pattern feature amount MP1 ′ does not match, and the copy code-added photographic paper XPc2 It is possible to detect that it is a duplicate and not an original.

  Further, as shown in FIG. 4, for example, the authentication code BC1 and the designated area AR1 in the code-added photographic paper XPc1 are cut out and pasted on other photographic paper to produce a photographic paper XPc3 with a modified code. However, since the restored print content certification information SP2 ′ restored from the authentication code BC1 and the print content SP1 of the code-added photographic paper XPc3 do not match, the print content SP1 of the altered-code-attached photographic paper XPc3 is altered. Can be detected.

  As described above, since it is possible to verify whether or not the code-added photographic paper XPc1 has been legitimately created from the original paper OP and to verify whether or not the print content SP1 of the photographic paper is legitimate, it is immediately possible to It is possible to discover unauthorized duplication or alteration of the photographic paper used as a high value-added medium such as a merchandise exchange medium or a content certification medium.

(2) Configuration of Identification Device In FIG. 5, reference numeral 1 denotes an identification device according to the present embodiment. A control unit 2 that controls the entire identification device 1 is connected to a scanner unit 4 and a printer unit 5 via a bus 3. And a display unit 6 including an LCD (Liquid Crystal Display) or the like is connected.

  The control unit 2 has a CPU (Central Processing Unit) configuration, and has a work memory made of RAM (Random Access Memory) and an information storage memory made of ROM (Read Only Memory).

  In this information storage memory, the position information of the designated area AR1 (FIG. 2) for each standard size of paper (hereinafter referred to as area position information), the character string information for two-dimensional barcode (hereinafter referred to as this). Various information such as code character string information) and programs are stored. Therefore, the control unit 2 executes various processes according to programs loaded in the work memory, using various information stored in the information storage memory as appropriate.

  In practice, when the control unit 2 (FIG. 5) receives an instruction from the operation unit (not shown) to print the print information including the print content SP1 and the authentication code BC1, the control unit 2 (FIG. 5) This is called a printing mode), and a pattern image reading command is sent to the scanner unit 4.

  Then, as a response result of this command, the control unit 2 is supplied with pattern image data (hereinafter referred to as pattern image data) D1 on the original photographic paper OP1 from the scanner unit 4.

  As shown in FIG. 6, the control unit 2 extracts a paper pattern feature amount MP1 from the pattern image data D1, and generates print content certification information SP2 based on the print content SP1. Then, the control unit 2 generates an authentication code BC1 composed of a two-dimensional barcode based on the combined information MX1 obtained by combining the paper pattern feature amount MP1 and the print content certification information SP2. Further, the control unit 2 combines the authentication code BC1 and the print content SP1 to generate print information and sends it to the printer unit 5.

  This print information is stored in the original paper OP1 in the printer unit 5 as the print content SP1 and the authentication code BC1. As a result, the control unit 2 stores the paper pattern feature amount MP1 and the print content SP1 on the paper surface of the original paper OP1 in a linked state through the authentication code BC1.

  In addition, when a predetermined identification command is given from the operation unit, the control unit 2 shifts to a second mode (hereinafter, this mode is referred to as an identification mode), and sends a pattern image reading command and a code reading command to the scanner unit 4. To send.

  As a response result of these commands, the control unit 2 prints pattern data on the code-added photographic paper XPc1 (hereinafter referred to as code-added pattern image data) D2 from the scanner unit 4 and the code-added photographic paper XPc1. The code image data D3, which is the result of reading the authentication code BC1 thus obtained, is given.

  As shown in FIG. 7, the control unit 2 extracts the comparison sheet pattern feature amount MP2 from the code-attached pattern image data D2 in the designated area AR1, and restores it by restoring from the code image data D3 in the authentication code BC1. The paper pattern feature amount MP1 ′ and the restored print content certification information SP2 ′ are obtained.

  Then, as shown in FIG. 8, the control unit 2 compares the restored paper pattern feature amount MP1 ′ with the comparison paper pattern feature amount MP2. Therefore, as a result of the comparison and collation, the control unit 2 determines whether or not the respective feature amounts exceed a predetermined threshold value, and if it can be recognized that both match, the code-added photographic paper XPc1 is legitimately determined. It is proved that the original paper OP1 itself has been created, that is, the original, but if the two do not match, the originality of the code-added photographic paper XPc1 is denied.

  Further, the control unit 2 can cause the user to compare the print content SP1 printed on the code-added printing paper XPc1 and the restored print content certification information SP2 ′ by displaying the restored print content certification information SP2 ′ on the display unit 6. If the user can recognize the coincidence, the print content SP1 of the code-added photographic paper XPc1 is proved that it has not been tampered with, that is, it is valid. The legitimacy of the print content SP1 on the code-added photographic paper XPc1 is denied.

  In this way, the control unit 2 can verify the originality of the code-added photographic paper XPc1 and the correctness of the print content SP1, so that it can detect unauthorized duplication or alteration of the code-added photographic paper XPc1, and thus the code-added photographic paper XPc1. It is designed to prevent unauthorized duplication and alteration.

  On the other hand, the scanner unit 4 (FIG. 5) has a pattern reading mode and a code reading mode. When a pattern image reading command is given from the control unit 2, a pattern reading code and a code reading command are given from the control unit 2. If it is, the code reading mode is executed.

  In practice, the scanner unit 4 (FIG. 5) is obtained by, for example, irradiating the original photographic paper OP1 or the code-added photographic paper XPc1 placed on the placement table and transmitting these in the pattern reading mode. The pattern projection light is imaged on a solid-state image sensor via an optical system. Then, the scanner unit 4 performs A / D (Analog / Digital) conversion processing or the like on the pattern image signal obtained from the solid-state image sensor, and uses the pattern image data D1 or the code-attached pattern image data D2 obtained as a result. It is sent to the control unit 2.

  Similarly, in the code reading mode, the scanner unit 4 irradiates, for example, the code-attached photographic paper XPc1 placed on the placing table and reflects the reflected code light through the optical system. An image is formed on a solid-state image sensor. Then, the scanner unit 4 performs A / D conversion processing or the like on the code image signal obtained from the solid-state imaging device, and sends the code image data D3 obtained as a result to the control unit 2.

  In this way, the scanner unit 4 can read the pattern image and the authentication code BC1 (FIG. 7) by executing the modes according to the various commands given from the control unit 2.

  On the other hand, when printing information is supplied from the control unit 2, the printer unit 5 (FIG. 5) performs a pulse width modulation process or the like on the printing information, and sends the resulting printing data to the printing head unit. To do. As a result, by driving the printing head unit based on the printing information, the printing content SP1 (FIG. 6) is printed on the printing paper (original paper OP1) set on the printing paper stand at this time, and the predetermined printing paper is used. An authentication code BC1 is printed at the position.

  On the other hand, when the restored print content certification information SP2 ′ (FIG. 8) restored from the authentication code BC1 is supplied from the control unit 2, the display unit 6 displays the restored print content certification information SP2 ′. ing.

(3-1) Print Content Certification Information Generation Processing In the print mode, the print content certification information generation unit 10 is a photograph, a character, or a combination image input from the outside or read from an information storage memory (not shown). Based on the data, for example, a concert admission ticket image is generated as the print content SP1. Then, the print content certification information generating unit 10 generates print content certification information SP2 based on the print content SP1. For example, when the print content SP1 is concert admission ticket information, information specifying the concert name, date and time, a concert such as a designated seat, admission conditions, and the like is generated. Then, the print content certification information generation unit 11 sends the print content certification information SP2 to the composite information generation unit 13.

  As a result, the print content proof information generation unit 10 can extract only the information that certifies the print content from the print content SP1, so that the data amount as the print content proof information SP2 can be reduced.

(3-2) Paper Pattern Feature Amount Extraction Processing When the pattern image data D1 is supplied from the scanner unit 4 (FIG. 5), the paper pattern image processing unit 12 (FIG. 9) performs the paper pattern feature from the pattern image data D1. An amount MP1 is extracted. Here, when the contents of the paper pattern feature amount extraction processing in the paper pattern image processing unit 12 are functionally classified, as shown in FIG. 7, a low frequency component extraction unit 21, an image separation unit 22, and an area division unit 23 and a paper pattern feature amount extraction unit 24.

  Actually, the control unit 2 inputs the pattern image data D1 supplied from the scanner unit 4 to the low frequency component extraction unit 21.

  When the pattern image data D1 is input, the low-frequency component extraction unit 21 acquires the area pattern image IM1 (FIG. 10A) in the designated area AR1 from the pattern image data D1, as shown in FIG. The low-frequency component pattern image IM2 (FIG. 10B) is extracted from the region pattern image IM1, and the low-frequency component pattern image IM2 is sent to the image separation unit 22 (FIG. 9).

  As a result, the low-frequency component extraction unit 21 generally removes various noise components contained in the high-frequency component of the image, prevents a decrease in the extraction accuracy of the paper pattern feature amount, and thus improves the reliability of the collation result in the collation unit 33. It is made to be able to let you.

  As shown in FIGS. 11A, 11B, and 11C, the image separation unit 22 converts the low-frequency component pattern image IM2 (FIG. 11A) extracted by the low-frequency component extraction unit 11 into The white component pattern image WIM (FIG. 11B) and the black component pattern image BIM (FIG. 11C) are separated.

  Specifically, the image separation unit 22 sequentially detects the luminance value of the low-frequency component pattern image IM2 for each pixel, extracts the white component pattern image WIM having a luminance value equal to or higher than the high luminance threshold, and this white component pattern The image WIM is sent to the area dividing unit 23.

  The image separation unit 22 extracts a black component pattern image BIM having a luminance value at which the detection result of each pixel in the low frequency component pattern image IM2 is equal to or lower than the low luminance threshold, and the black component pattern image BIM is divided into region division units. 23.

  In this way, the image separation unit 22 can reduce the complexity of the pattern pattern by separating the low-frequency component pattern image IM2 into the white component pattern image WIM and the black component pattern image BIM. As a result, the image separation unit 22 can prevent a decrease in the extraction accuracy of the paper pattern feature amount in the paper pattern feature amount extraction unit 24 due to the high degree of complexity of the pattern pattern.

  As shown in FIG. 12, the area partition unit 23 has an area in which the pattern of the white component pattern image WIM (FIG. 11B) is a unit of a set of adjacent white pixels (hereinafter, this is referred to as a white dama). ), And the black component pattern image BIM (FIG. 11C) has a pattern divided into regions (hereinafter referred to as “black dama”) having a set of adjacent black pixels as a unit.

  Specifically, the area dividing unit 23 detects all white pixels from the white component pattern image WIM supplied from the image separating unit 22, and then adjoins any target pixel AP as shown in FIG. A total of 8 pixels (hereinafter referred to as 8 neighboring pixels) of 4 pixels in the vertical and horizontal directions and 4 pixels in the diagonal direction are sequentially connected.

  The area dividing unit 23 is also configured to form a plurality of black dams BD1 to BDn for the black component pattern image BIM supplied from the image separation unit 12 in the same manner as the white component pattern image WIM.

  In this way, the area dividing unit 23 divides the pattern included in the white component pattern image WIM into a plurality of white damascene WDs (WD1 to WDn) and the pattern included in the black component pattern image BIM into a plurality of black damascene BDs. By dividing it into (BD1 to BDn), the pattern can be subdivided.

  As a result, the area division unit 23 can finely analyze the patterns included in the white component pattern image WIM and the black component pattern image BIM, thereby improving the paper pattern feature amount extraction accuracy in the paper pattern feature amount extraction unit 24. Has been made to get.

  Further, the area dividing unit 23 is configured to remove lumps that are equal to or less than a predetermined number of connections (FIG. 13B) from the divided white component pattern image WIM (FIG. 13A). The remaining white dama data WD obtained as a result of the removal is sent to the paper pattern feature amount extraction unit 24.

  Similarly, the area dividing unit 23 (FIG. 9) removes dams that are equal to or less than a predetermined number of connections from the black component pattern image BIM, and uses the remaining black dama data BD obtained as a result of the removal as a paper pattern feature amount extraction unit. 24.

  As a result, the area dividing unit 23 can extract only the feature portions of the patterns included in the white component pattern image WIM and the black component pattern image BIM as white dama data WD and black dama data BD. In this case, the accuracy of extracting the paper pattern-like feature amount can be further improved.

  The paper pattern feature amount extraction unit 24 extracts the paper pattern feature amount by calculating the shape feature amount in the white dama data WD and the black dama data BD. In this case, when the paper pattern feature quantity extraction unit 24 calculates the feature quantity of each shape in the white dama data WD and the black dama data BD as they are, the shape is complicated and difficult, so the white dama data WD and the black dama data are calculated. Each of the BD shapes is approximated by a rectangle, and a rectangular information value obtained as a result is extracted as a paper pattern feature amount MP1. Then, the paper pattern feature amount extraction unit 24 sends the paper pattern feature amount MP1 to the composite information generation unit 13.

  Then, the PC 54 (FIG. 16) sends a print processing end notification to the web management server 52 indicating that the print processing has ended in accordance with the user's operation.

  In addition to this configuration, the online ticket system 50 performs a confirmation process for confirming that the coded ticket CT has been normally issued.

  When the above-described print processing end notification is supplied, the control unit 52A of the web management server 52 sends a photographic paper image acquisition request image to the effect that the code-added pattern image data D2 of the code-added ticket CT is acquired to the PC 54. To do. As a result, the control unit 52A displays the photographic paper image acquisition request image on the display unit 54B of the PC 54. Then, the control unit 52A causes the scanner unit 54A to acquire the code-attached pattern image data D2 of the code-added ticket CT based on the user's operation on the PC 54 based on the pattern image acquisition request image, and supplies it to the control unit 52A via the Internet 53. It is made to let you.

  When the code-attached pattern image data D2 is supplied, the control unit 52A extracts the comparison sheet pattern feature amount MP2 from the code-added pattern image data D2 and restores it from the authentication code BC1. A pattern feature amount MP1 ′ and restoration ticket content certification information TN2 ′ are obtained. Then, the control unit 52A compares the restored paper pattern feature amount MP1 ′ with the paper pattern feature amount MP1 read from the information memory.

  Accordingly, as a result of the comparison and collation, the control unit 52A determines whether or not the respective feature amounts exceed the predetermined threshold value, and if it can be recognized that both match, this indicates that the authentication code BC1 is the original paper. This means that the printing is normally performed in OP1, and a ticket issuance end notification indicating that the issuance of the coded ticket CT has been completed is sent to the PC 54, and the issuance of the coded ticket CT is completed.

  On the other hand, when the control unit 52A recognizes that the feature amounts do not match as a result of the comparison and collation, this means that the authentication code BC1 is not normally printed on the original paper OP1. Then, a notification that the pattern image data D1 of another original paper OP2 is acquired is sent again to the PC 54, and the process relating to the issuance of the code-added ticket CT is performed again.

  Thus, the control unit 52A, for example, creates a new original paper OP2 even when the authentication code BC1 is printed on paper other than the original paper OP1 or when it is not printed normally due to a trouble due to a printing mistake or the like. Thus, the code-added ticket CT can be issued again, and the ticket can be issued reliably.

  In this way, in the online ticket system 50, the pattern image data D1 is acquired from the original paper OP1 by the scanner unit 54A of the PC 54, and the pattern image data D1 and the ticket contents TN1 generated by the control unit 52A of the web management server 52 are used. Since the printing information PI generated from the image is printed on the original paper OP1 by the scanner unit 54C of the PC 54C, a ticket can be issued by the PC 54, and a coded ticket CT can be issued online such as the Internet. .

  At this time, the PC 54 can obtain the pattern image data D1 from the original paper OP1, and can issue a ticket by simply printing the print information PI generated by the web management server 52. Therefore, special software is required. In other words, the ticket CT with code can be issued with a simple configuration.

(5-1-2) Ticket Identification As shown in FIG. 16, the collation device 56 includes a control unit 56A, a scanner unit 56B, and a display unit 56C, and controls each unit under the control of the control unit 56A. By doing so, various processes can be executed.

  The control unit 56A, the scanner unit 56B, and the display unit 56C of the verification device 56 correspond to the control unit 2, the scanner unit 4, and the display unit 6 in the identification device 1 (FIG. 5), respectively, and perform the above-described processing. ing.

  In practice, the control unit 56A of the collation device 56 starts processing when an instruction for identifying the originality of the coded ticket CT and the validity of the print content is given via the operation unit (not shown).

  The control unit 56A restores the paper pattern feature amount MP1 ′ by the above-described authentication code restoration process (4-1) from the code image data D3 in the authentication code BC1 of the code ticket with code CT (FIG. 17) acquired by the scanner unit 56A. In addition, the restoration ticket content certification information TN2 ′ is obtained, and the comparison paper pattern feature amount MP2 is obtained from the code pattern image data D2 in the designated area AR1 by the above-described paper pattern feature amount extraction process (3-2).

  Then, the control unit 56A (FIG. 16) performs a matching process (4-2) between the restored paper pattern feature value MP1 ′ and the comparison paper pattern feature value MP2, and also displays the restored ticket content certification information TN2 ′ on the display unit 56C. The authenticity of the ticket CT with code and the validity of the ticket content TN1 can be verified by allowing the user to directly compare the ticket content TN1 and the restored ticket content certification information TN2 ′ by visual comparison. The legitimacy of CT can be identified.

  At this time, the verification device 56A can perform the above-described verification process using the paper pattern in the designated area AR1 of the code-added ticket CT and the authentication code BC1, and does not need to be connected to the management server. Compared with the conventional method for collating information with management information managed by the management server, the configuration can be simplified and the processing time required for collation can be shortened because communication time is not required. Can do.

  In the online ticket system 50, since the collation device 56A can quickly identify the originality of the ticket CT with code printed by the PC 54 and the validity of the ticket content TN1, the illegally copied or altered ticket is used. Thus, unauthorized duplication or alteration of the ticket can be prevented.

  As a result, the online ticket system 50 can prevent illegal duplication or alteration of the ticket by the identification method, so that it is not necessary to take special alteration prevention measures on the ticket content TN1 or the original paper OP1, so that a special issue is issued for issuing the ticket. Can issue original paper OP1, which is ordinary paper, and general-purpose electronic communication equipment such as a personal computer, and issue a coded ticket CT to an unspecified number of users online without the need for equipment or paper. Can do.

  In addition, in the online ticket system 50, the code ticket CT with the code can be identified as valid only by combining the paper pattern of the solid paper and the data stored as the authentication code BC1, and therefore, for example, hacking or the like. Thus, even when electronic information such as the pattern image data D1 and the print information PI is leaked, the electronic information can be prevented from being illegally used.

  In this way, the online ticket system 50 can safely issue and use the coded ticket CT online.

(5-2) Identity Confirmation System (5-2-1) Configuration of Identity Confirmation System In FIG. 18, reference numeral 90 denotes an identity confirmation system as a whole, which includes an ATM (Automatic teller machine) 91, a management server 92, and a cash card 94. And an identification card 95 (95A and 95B in FIG. 18). The ATM 91 is connected to the management server 92 to exchange information.

  In the identity verification system 90, when the user uses the ATM 91, a cash card 94 and an identity verification card 95 are required as ID cards for identity verification. That is, the identity verification card 95 is used as an ID card for confirming that the user is the user himself / herself when the user uses the cash card 94.

  Here, the personal identification card 95 includes, for example, the user's name and the date and time when the ATM 91 was used last time as the print content SP1, a designated area AR1 (ARa, ARb) is provided at the lower right of the page, and authentication is provided in the vicinity thereof. A code BC1 (BCa, BCb) is printed. The authentication code BC1 is a time based on the time when the personal identification card 95 is issued in addition to the paper pattern feature amount MP1 extracted from the designated area AR1 and the print content certification information SP2 based on the print content SP1. Information (hereinafter referred to as issue time information) is stored.

  The identity verification card 95 is newly issued when the user uses the ATM 91 for the next use of the ATM 91. That is, this identity verification card 95 is issued every time the user uses the ATM 91.

  As shown in FIG. 19, the ATM 91 is configured by a control unit 91D that controls the entire ATM 91, a scanner unit 91A connected via a bus 91E, a display unit 91B, a printer unit 91C, and a communication interface unit 91E. Is done. The control unit 91D, the scanner unit 91A, and the printer unit 91C correspond to the control unit 2, the scanner unit 4, and the printer unit 5 of the identification device 1, respectively, and execute various processes.

  The identity verification card 95 corresponds to the code-added printing paper XPc1 on which the authentication code BC1 is printed.

  On the other hand, the management server 92 manages the management customer information and stores the issuance time information and the print content certification information SP2 stored in the identity verification card 95A in association with the management customer information. Accordingly, the print content certification information SP2 based on the management customer information is generated and the issue time information is generated and sent to the ATM 91.

(5-2-2) Processing Contents of Identity Verification System Next, processing contents of the identity verification system will be described.

  When the cash card 94 is authenticated, the control unit 91D of the ATM 91 makes a transition to the identification mode and requests the user to supply the personal identification card 95 by displaying on the display unit 91B. When the identity verification card 95A is supplied as a result of this request, the control unit 91D acquires the code-attached pattern image data D2 and the code image data D3 from the identity verification card 95A by the scanner unit 91A.

  The control unit 91D restores the restored paper pattern feature amount MP1 ′, the restored print content certification information SP2 ′, and the restoration issue time information from the code image data D3 by the above-described authentication code restoration process (4-1). In addition, the comparison paper pattern feature amount MP2 is acquired from the code-pattern image data D2 by the paper pattern feature amount extraction process (3-2). Then, the control unit 91D verifies the originality by collating the restored paper pattern feature amount MP1 ′ and the comparison sheet pattern feature amount MP2 by the collation process (4-2).

  Further, the control unit 91D generates a specific information supply command which is a command for supplying the print content certification information SP2 and the issue time information, and sends the specific information supply command to the management server 92.

  When the specific information supply command is supplied from the ATM 91 via the communication interface 92B, the control unit 92A of the management server 92 specifies the latest issue time information and print content certification information SP2 based on the management customer information, The issue time information and the print content certification information SP2 are sent to the ATM 91.

  When the issue time information and the print content certification information SP2 are supplied as the response result of the specific information supply command, the control unit 91D of the ATM 91 receives the print content certification information SP2 and the restored print content certification information SP2 ′ restored earlier. Is matched.

  When the print content certification information SP2 and the restored print content certification information SP2 ′ match, the ATM 91 determines that the personal identification card 95A is the legitimate user personal identification card 95A and is legitimate. On the other hand, if the two do not match, it is determined that the personal identification card 95A is not from a legitimate user. As described above, the ATM 91 can verify the authenticity of the personal identification card 95A.

  Further, the control unit 91D collates the latest issue time information acquired from the management server 92 with the restored issue time information restored earlier.

  When the latest issuance time information and the restoration issuance time information match, the control unit 91D determines that the personal identification card 95A has been issued most recently. On the other hand, if the two do not match, the controller 91D determines that the identity verification card 95 is not the latest. In this way, the ATM 91 can identify whether or not the personal identification card 95A is the latest one.

  Accordingly, this ATM 91 can not only verify the originality and correctness of the identity verification card 95A, but also can clarify the context of the issue time by checking the restoration issue time information with the management server 92. It is possible to use only the identity verification card 95A issued to

  Further, since only the latest identity verification card 95 can be used, it is possible to prevent the old identity verification card 95 from being misused.

  The ATM 91 then provides the service after authentication of the cash card 94 and identification of the identity verification card 95, and when the service is completed, the identity verification is newly performed together with a usage certificate such as a usage statement that proves the provision of the service. A card 95B is issued.

  In this case, when the control unit 91D of the ATM 91 acquires the pattern image data D1 from the designated area AR2 of the new original paper OP2 by the scanner unit 91A, the paper pattern feature amount MP1 is extracted by the above-described paper pattern extraction process (3-2). To do. Then, the control unit 91D sends a generation information supply command, which is a command for supplying the print content certification information SP2 and the issue time information, to the management server 92 via the communication interface 91E.

  On the other hand, when the generation information supply command is supplied, the control unit 92A of the management server 92 recognizes the reception time when the information supply command is received as the issue time information, and generates the print content certification information SP2 from the management customer information. Then, the issue time information and the print content certification information SP2 are sent to the ATM 91 via the communication interface 92B, and these pieces of information are stored in association with the management customer information.

  When the issue time information and the print content certification information SP2 are supplied, the control unit 91D of the ATM 91 generates composite information from the paper pattern feature amount MP1 extracted earlier, the issue time information, and the print content certification information SP2. The authentication code BC1 is generated by the process (3-3) and the print information generation process (3-4). The control unit 91D issues the personal identification card 95 by printing the authentication code BC1 and the predetermined print content SP1 by the printer unit 91C.

  Thereby, in ATM91, since the identity verification card 95 is updated every time, it is possible to prevent the identity verification card 95 from being altered based on the old identity verification card 95. Security can be improved.

  In addition, in the ATM 91, since the identity verification card 95 is issued every time the ATM 91 is used and is used only once, the lost old identity verification card 95 can be prevented from being repeatedly used and misused.

  Further, in the ATM 91, since the personal identification card 95 is printed together with a usage certificate indicating the state of using the ATM 91, no special equipment is required for printing the personal identification card 95, and a simple configuration can be achieved. .

  Furthermore, in ATM91, since the personal identification card 95 is used instead of the personal identification by the personal identification number required when using ATM91, it is not necessary for the user to memorize the personal identification number, and the ATM91 can be easily used. Is possible.

  Further, the identity verification card 95 is adapted to identify the authenticity of the identity verification card 95 by a unique paper pattern of the paper. The identity verification card 95 is required for identification processing, and a pattern image is displayed by skimming. Even if it is acquired, it is impossible to produce a paper pattern from the pattern image, so that the identification card 95 can be prevented from being altered by skimming.

  Further, since the identity verification card 95 is used incidentally to the cash card 94 that is an ID card as a legitimate user, unlike the cash card 94, it cannot be skimmed or altered. Can be compensated for, and security can be improved.

(6) Operation and effect according to the present embodiment In the above configuration, the identification device 1 of the present invention includes the paper pattern feature amount MP1 extracted from the pattern image data D1 acquired from the original paper OP1 and the contents to be proved. The print content certification information SP2 representing the content of the print content SP1 is synthesized, and the resultant composite information MX1 is used as an authentication code BC1 as a reference for detecting alteration of the original paper OP1 and the original paper together with the print content SP1. Print on OP1. As a result, the printed content SP1 and the paper pattern feature amount MP1 are registered in the printed code-added photographic paper XPc1 through the authentication code BC1.

  In this case, the identification apparatus 1 obtains the code-added photographic paper XPc1 from the restored paper pattern feature amount MP1 ′ obtained from the authentication code BC1 registered in the code-added photographic paper XPc1 and the designated area AR1. The originality can be verified by comparing and comparing the comparison sheet pattern feature amount MP2 obtained, and the print content SP1 is compared with the restored print content certification information SP2 ′ obtained from the authentication code BC1. The validity of the content SP1 can be verified, and thus the originality of the code-added photographic paper XPc1 and the validity of the printing content SP1 can be identified.

  On the other hand, in the online ticket system 50, the identification device 1 is configured by connecting a PC 54 and a web management server 52 via the Internet 53. Therefore, in the online ticket system 50, the web management server 52 extracts the paper pattern feature amount MP1 from the pattern image data D1 of the original paper OP1 acquired by the PC 54, and print content certification information SP2 representing the content of the ticket content SP1. The paper pattern feature amount MP1 is combined, and the combined information MX1 generated as a result is printed on the original paper OP1 by the PC 54 as the authentication code BC1 together with the print content SP1.

  As a result, in the online ticket system 50, normal paper can be used as the original paper OP1, and the pattern image data D1 is acquired as the PC 54 and sent to the web management server 52, and the supplied print content SP1 and authentication code BC are displayed. Since it is only necessary to print, and a general-purpose personal computer or the like can be used, a code-added ticket CT in which the print content SP1 and the authentication code BC1 are printed on the original paper OP1 can be issued at home or at work.

  On the other hand, the identity verification system 90 is configured by connecting the management server 92 and the ATM 91, and is generated by the management server 92 using the paper pattern feature amount MP 1 extracted from the pattern image data D 1 acquired from the original paper OP 1 by the ATM 91. The print content certification information SP2 representing the content of the printed content SP1 and the issue time information representing the creation time are synthesized by the ATM 91, and the composite information MX1 generated as a result by the ATM 91 is used as an authentication code BC1 together with the print content SP1 and the original paper. Print on OP1. Therefore, in the identity verification system 90, the authentication code BC1 in which the paper pattern feature amount MP1 and the issue time information are linked is registered in the identity verification card 95, and the identity verification card 95 is stored in the management server 92 via the ATM 91. As a part of the usage certificate indicating the usage status, it is sequentially issued every time the ATM 91 is used, and the latest time information TP is held by the management server 92.

  As a result, the identity verification system 90 checks whether or not the identity verification card 95 is the latest by comparing the latest issue time information with the restoration issue time information restored from the authentication code BC1. Since it can be identified, only the latest identity verification card 95 can be used, and the old identity verification card 95 can be prevented from being misused. Further, since the personal identification card 95 is identified by a unique paper pattern of the paper, even if the information of the paper pattern itself is leaked due to loss, it does not affect the next personal identification card 95 and is safe and new. An identity verification card 95 can be issued.

  In addition, since the personal identification card 95 is used as a password for unlocking the cash card 94 and making it usable, the user does not need to store the password and can easily store the cash card 94. The lock can be released. Since the personal identification card 95 requires a paper pattern itself for identification, that is, the personal identification card 95 itself cannot be altered by skimming and is tangible, the user is aware of the identity card 95 being stolen or lost. Therefore, the risk of unauthorized use due to alteration, theft and loss can be reduced. Furthermore, since this identity verification card 95 can be used only once, it is possible to prevent unauthorized use of the identity verification card 95 that has been lost or the like. Security can be improved.

  According to the above configuration, since the identification device 1 can identify the originality of the code-added photographic paper XPc1 and the legitimacy of the print content SP1, the unauthorized copying or alteration of the print content SP1 of the code-added photographic paper XPc1 is possible. Can be prevented.
