Abstract
Description
[Technical field]
[0001] The present invention relates to an authenticity determining device and a program therefor. [Background technology]
[0002] When opening an account at a financial institution, identification such as a driver's license is required, but there has been an increase in cases of people forging driver's licenses or other documents to open accounts under the guise of another person for the purpose of committing criminal acts such as special fraud.
[0003] For this reason, there is a demand for technology to determine such counterfeits. For example, Patent Document 1 describes an authenticity determination device that determines the authenticity of a driver's license or other card by determining whether there are inconsistencies in the text information on the card.

[0004] [Patent Document 1] JP 2019-209603 A Summary of the Invention [Problem to be solved by the invention]
[0005] The authenticity determination device of Patent Document 1 can detect driver's licenses and other documents with forged faces, but in recent years, in light of increasingly strict identity verification, there has been a demand for technology that can more reliably determine the authenticity of driver's licenses and detect forgeries.
[0006] The present invention has been made in consideration of the above problems, and has an object to provide an authenticity determining device etc. that can more reliably determine the authenticity of a driver's license. [Means for solving the problem]
[0007] A first invention for solving the above-mentioned problems is a driver's license authenticity determination device, which has a verification means for verifying whether IC chip information obtained from an IC chip of the driver's license matches character information on the face of the driver's license obtained from an image of the driver's license, and a discrimination means for discriminating whether or not there is a contradiction between the content of the character information on the face of the driver's license obtained from an image of the driver's license and the content of another character information on the face of the driver's license obtained from an image of the driver's license. The discrimination means extracts the band color of the expiration date, which is character information on the face of the card, from the image, and if the year of the expiration date is not within a predetermined range based on the issue date and the band color, which are other character information on the face of the card, it is determined that there is a contradiction. The authenticity determination device is characterized by: The discrimination means discriminates, for example, a plurality of discrimination items, and the discrimination means further comprises: Determine whether there is a contradiction between the content of the character information on the face of a driver's license obtained from an image of the driver's license and the attributes of the character information on the driver's license. In order to determine this, if the license number, which is the character information that should be written as a number of a specified number of digits on the driver's license, is not a number of the specified number of digits, a contradiction is found. Things to do It is also preferable that the discrimination means further compares the date of birth, which is character information on the face of the card, with another character information on the face of the card, which is a type of exemption, and discriminates whether or not there is a contradiction between the date of birth and the type of exemption.
[0008] In the present invention, the authenticity of a driver's license is determined by comparing the IC chip information with the character information on the face of the driver's license and determining whether or not there is a contradiction in the character information on the face of the driver's license. By determining the authenticity based on these results, the authenticity of the driver's license can be determined more reliably.
[0009] The text information used for authenticity determination indicates, for example, a specific date, and the authenticity of the driver's license can be suitably determined based on whether the content of the information matches the IC chip information or whether there is a contradiction. Inconsistencies in text information can be broadly divided into cases where there is a contradiction between the content of one piece of text information and the content of another piece of text information, and cases where there is a contradiction between the content of one piece of text information and the attributes of that piece of text information, and both cases can be determined as contradictions in the present invention.
[0010] When the IC chip of the driver's license cannot be read, the authenticity determining device determines that the matching result by the matching means is inaccurate, and can determine the authenticity of the driver's license from the discrimination result by the discrimination means. If the IC chip cannot be read, the possibility that the driver's license is genuine even if the IC chip is broken should be considered. The driver's license should not be deemed invalid simply because the IC chip cannot be read, and authenticity can be determined by also taking into account whether there are any inconsistencies in the text information on the face of the card.
[0011] The authenticity determination device can determine that the driver's license is not genuine if the comparison means determines that the IC chip information and the character information do not match, or if the discrimination means determines that there is a contradiction. The authenticity determination device can make a more reliable determination by determining that the driver's license is not genuine if a negative result is obtained by either the comparison means or the discrimination means.
[0012] The IC chip information is information that can be read without inputting a password, for example. This eliminates the need to enter a personal identification number (PIN) to read the IC chip information, simplifying the process of determining authenticity.
[0013] No. 2 The invention relates to a computer, a driver's license authenticity determination device, which includes a verification means for verifying whether IC chip information obtained from an IC chip of a driver's license matches character information on the face of the driver's license obtained from an image of the driver's license, and a determination means for determining whether there is a contradiction between the content of the character information on the face of the driver's license obtained from an image of the driver's license and the content of another character information on the face of the driver's license obtained from an image of the driver's license. The discrimination means extracts the band color of the expiration date, which is character information on the face of the card, from the image, and determines that there is a contradiction if the year of the expiration date is not within a predetermined range based on the issue date, which is another character information on the face of the card, and the band color. This is a program that functions as an authenticity determination device. 。 Effect of the Invention
[0014] According to the present invention, it is possible to provide an authenticity determining device etc. that can more reliably determine the authenticity of a driver's license. [Brief description of the drawings]

[Figure 6] 11A and 11B are diagrams for explaining determination of the presence or absence of a contradiction in character information.
[0016] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.
[0017] (1. Authenticity Determination System 1) Fig. 1 is a diagram showing an authenticity determination system 1 having an authenticity determination device 3 according to an embodiment of the present invention. As shown in Fig. 1, the authenticity determination system 1 has a reading device 2 and an authenticity determination device 3. The reading device 2 and the authenticity determination device 3 are connected to each other so as to be able to communicate with each other via wireless or wired communication means.
[0018] The reading device 2 reads the driver's license 10 and includes a scanner 21 and an IC chip reading unit 22 .
[0019] The scanner 21 is for acquiring an image of the face of the driver's license 10, and may be, for example, a known scanning device.
[0020] The IC chip reading unit 22 reads data stored in an IC chip (not shown) of the driver's license 10, and may be, for example, a known reader / writer.
[0021] In this embodiment, the scanner 21 and the IC chip reading unit 22 are configured as an integrated device, but they may be configured as separate devices. Also, a camera or the like can be used to capture an image of the face of the driver's license 10.
[0022] The authenticity determination device 3 determines the authenticity of the driver's license 10 based on the face image of the driver's license 10, etc. Fig. 2 is a diagram showing the hardware configuration of the authenticity determination device 3, and the authenticity determination device 3 can be realized by a computer configured by connecting a control unit 31, a storage unit 32, a display unit 33, an input unit 34, a communication control unit 35, etc. via a bus or the like. However, the authenticity determination device 3 is not limited to this, and various configurations can be used as appropriate.
[0023] The control unit 31 is composed of a CPU, a ROM, a RAM, etc. The CPU loads programs related to the processing of the authenticity determination device 3 stored in a storage medium such as the memory unit 32 or ROM into a work area on the RAM and executes them. The ROM is a non-volatile memory, and permanently stores programs such as the boot program and BIOS, data, etc. The RAM is a volatile memory, and temporarily stores programs and data loaded from the memory unit 32, ROM, etc., and also has a work area used by the control unit 31 to perform various processes.
[0024] The storage unit 32 is a hard disk drive, a solid state drive, a flash memory, or the like, and stores programs executed by the authenticity determination device 3 in the processes described below, data necessary for executing the programs, an OS, etc. These programs and data are read out and executed by the control unit 31 as necessary.
[0025] The display unit 33 includes a liquid crystal display or the like. The input unit 34 is used to input various information to the authenticity determination device 3 . The communication control unit 35 is a communication interface that mediates communication, and performs communication with the reader 2.
[0026] (2. Driver's License 10) The driver's license 10 is an identification card that is the subject of authenticity determination in this embodiment, and is used for identity verification by financial institutions, mobile phone carriers, and the like.
[0027] Figure 3 shows an example of the face of a driver's license 10. On the face of the driver's license 10, text information such as the driver's name 11, date of birth 12, address 13, date of issue of the driver's license 14 and expiration date 15, the type of license 16 under which the driver obtained the driver's license and the date of acquisition 17, the name of the prefectural public safety commission 18 that issued the driver's license 10, and the license number 19 are each formed in predetermined positions.
[0028] The driver's license 10 also has a built-in IC chip (not shown), which stores part of the text information on the face of the card as data. To read the data, a PIN must be entered as a personal identification number, but the IC chip also stores data that can be read without entering a PIN, such as the expiration date and issue date of the driver's license 10.
[0029] (3. Functions of the Authenticity Judgment Device 3) 4 is a diagram showing a functional configuration of the authenticity determination device 3. The authenticity determination device 3 includes a matching means 301, a discrimination means 302, and the like.
[0030] The comparison means 301 is a means for the control unit 31 of the authenticity determination device 3 to compare whether or not the IC chip information obtained from the IC chip of the driver's license 10 matches the character information obtained from the face image of the driver's license 10.
[0031] The determination means 302 determines whether or not there is a contradiction in the character information obtained by the control unit 31 of the authenticity determination device 3 from the face image of the driver's license 10. The details will be described later.
[0032] (4. Authenticity determination method) Fig. 5 is a flowchart showing the authenticity determination method executed by the authenticity determination device 3. S1 to S2, S5 to S6, and S9 in Fig. 5 are processes executed by the reading device 2, and other processes are executed by the control unit 31 of the authenticity determination device 3 by controlling each part of the authenticity determination device 3. The process in Fig. 5 is started, for example, by setting the driver's license 10 in a specified position of the reading device 2 and transmitting an instruction to start processing from the authenticity determination device 3 to the reading device 2.
[0033] In this embodiment, first, the reading device 2 obtains an image of the face of the driver's license 10 by the scanner 21 (S1), and transmits the image of the face of the driver's license 10 to the authenticity determination device 3 (S2).
[0034] When the authenticity determination device 3 receives the face image of the driver's license 10 (S3), it performs OCR (Optical Character Recognition) processing on the face image (S4) to obtain character information required for authenticity determination, such as the issue date 14 and expiration date 15, as character information on the face of the driver's license 10. Since the OCR processing is known, its description will be omitted.
[0035] The reading device 2 further reads data (IC chip information) from the IC chip of the driver's license 10 by the IC chip reading unit 22. If the reading device 2 can read the data from the IC chip (S5; YES), it transmits the read data to the authenticity determination device 3 (S6). In this embodiment, data on the issue date and expiration date of the driver's license 10, which can be read without entering a PIN, is read from the IC chip and transmitted to the authenticity determination device 3.
[0036] When the authenticity determination device 3 receives the IC chip data from the reading device 2 (S7), it compares the IC chip data with the character information on the face of the card obtained in S4 (S8).
[0037] In S8, the authenticity determination device 3 compares the issue date of the driver's license 10 read as data from the IC chip with the issue date 14 of the driver's license 10 obtained as character information on the face from the face image of the driver's license 10. Also, it compares the expiration date of the driver's license 10 read as data from the IC chip with the expiration date 15 of the driver's license 10 obtained as character information on the face from the face image of the driver's license 10.
[0038] If the reading device 2 is unable to read the data on the IC chip (S5; NO), it transmits a message to the authenticity determination device 3 indicating that the data could not be read (S9), and the authenticity determination device 3 receives this message (S10).
[0039] If the comparison in S8 described above shows that either the issue date or the expiration date of the driver's license 10 do not match, the authenticity determination device 3 determines the comparison result to be a mismatch (NO) (S11; NO), and displays on the display unit 33 that the driver's license 10 is not authentic (S12).
[0040] Furthermore, if the comparison in S8 above finds that both the issue date and the expiration date of the driver's license 10 match, the authenticity determination device 3 determines that the comparison result is a match (YES) (S11; YES), and then determines whether there is a contradiction in the text information on the face of the driver's license 10 (S13).
[0041] If the authenticity determination device 3 is unable to read the data on the IC chip, it determines that the comparison result is unverifiable (S11; unverifiable), and in this case too, it determines whether or not there is a contradiction in the text information on the face of the driver's license 10 (S13).
[0042] S13 will be described in detail later. If the authenticity determination device 3 determines in S13 that the character information on the face of the card has a contradiction (S14; YES), the authenticity determination device 3 determines that the driver's license 10 is not authentic, displays that fact on the display unit 33, and ends the process (S12).
[0043] On the other hand, if the authenticity determination device 3 determines in S13 that there is no contradiction in the text information on the face of the card (S14; NO), it determines that the driver's license 10 is authentic, displays that fact on the display unit 33, and ends the process (S15).
[0044] In this embodiment, as described above, the authenticity of the driver's license 10 can be determined from both the comparison result in S11 and the discrimination result in S14. The person in charge can check the authenticity determination result displayed on the display unit 33 and decide on the subsequent processing.
[0045] (5. Determining whether the text information on the card contains inconsistencies) In the above-mentioned S13, it is determined whether or not the character information obtained from the card face image has a contradiction. The contradiction in the character information can be broadly divided into a case where there is a contradiction between the content of one piece of character information and the content of another piece of character information, and a case where there is a contradiction between the content of one piece of character information and the attribute of the character information in the driver's license 10. In the former case, it can be determined that there is a contradiction when the content of one piece of character information is not within a predetermined value or range corresponding to the content of the other piece of character information, and in the latter case, it can be determined that there is a contradiction when the content of the character information is not within a predetermined value or range corresponding to the attribute of the character information.
[0046] (5-1. Cases where there is a contradiction between the content of text information and the content of other text information) An example of a case in which there is a contradiction between the content of one character piece and the content of another character piece is when there is a specified relationship between the issue date 14 and the expiration date 15, as determined from legal or other considerations, and when viewed from that relationship, there is a contradiction between the issue date 14 and the expiration date 15 obtained from the card face image.
[0047] For example, as shown in Fig. 6(a), assume that there is a relationship in which the year of expiration date 15 of driver's license 10 falls within a range of two years to six years after issue date 14. In this case, if the issue date 14 or expiration date 15 of driver's license 10 is forged, causing the year of expiration date 15 to fall outside the above range, it is determined that there is a discrepancy in content between issue date 14 and expiration date 15. Note that the above range differs depending on the band color (background color, e.g., blue or gold) of expiration date 15, so authenticity determination device 3 extracts the band color from the face image of driver's license 10 as necessary.
[0048] Also, as shown in Figure 6(b), assume that there is a relationship in which the month of expiration date 15 of driver's license 10 is one month after the month of date of birth 12. In this case, if the date of birth 12 or expiration date 15 of driver's license 10 is forged, and as a result the month of expiration date 15 becomes a month outside the above relationship, it will be determined that there is a discrepancy in content between date of birth 12 and expiration date 15.
[0049] The above is an example of comparing text information indicating specific dates, but other text information may be used for comparison. For example, the date of birth 12 obtained from the face image of the card and the type of exemption 16 can be compared to determine whether there is a discrepancy between their contents. In this case, the authenticity determination device 3 obtains the person's current age from the date of birth 12, and if the age is not within a range predetermined according to the content of the type of exemption 16, it determines that there is a discrepancy between the date of birth 12 and the type of exemption 16.
[0050] For example, if the contents of license type 16 include a medium-sized vehicle license, the age required from date of birth 12 must be 18 years of age or older (because legally, a medium-sized vehicle license can only be obtained by those aged 18 or older), and if the age required from date of birth 12 is not within that range, there will be a contradiction.
[0051] (3-2. Cases where there is a discrepancy between the content of the text information and the attributes of the text information on the driver's license 10) An example of a case in which there is a contradiction between the content of the character information and the attributes of the character information on the driver's license 10 is when the content of the date of birth 12 obtained from the face image of the card contradicts the attributes (indicating the date of birth of the holder of the driver's license 10).
[0052] For example, if the date of birth 12 is an impossible date, such as "Showa 70," "13th," or "April 31st," it is determined that there is a contradiction in the content. The same applies to the issue date 14, expiration date 15, acquisition date 17, etc. of the driver's license 10, and appropriate value ranges for dates (for example, Showa 1 to 64, month 1 to 12, April 1 to 30, etc.) are recorded in advance in the memory unit 32 of the authenticity determination device 3, and the presence or absence of a contradiction can be determined by referring to the range. Furthermore, it can also be determined that there is a contradiction when the current age obtained from the date of birth 12 is too young to be considered a normal holder of the driver's license 10.
[0053] Furthermore, if the issue date 14 is a date on which the driver's license 10 was not actually issued, for example, a certain period during the year-end and New Year holidays or a Saturday, it is determined that there is a contradiction between the content of the issue date 14 and its attribute (the date on which the driver's license 10 was issued). The authenticity determination device 3 records in advance in the memory unit 32 the dates on which the driver's license 10 was not issued, and can refer to this to determine whether or not there is a contradiction.
[0054] In addition, if the number of digits in license number 19 is not a predetermined value (for example, 12 digits), it can be determined that there is a contradiction between the contents of license number 19 and its attribute (being a number with a predetermined number of digits).
[0055] The determination of the presence or absence of a contradiction described in 3-2 above may be used in combination with the determination of the presence or absence of a contradiction described in 3-1 above. For example, it is possible to determine whether there is a contradiction in the attributes of the date of birth 12 obtained from the card face image, and whether there is a contradiction in the contents of other character information such as the expiration date 15.
[0056] In the above-mentioned S13, the discrimination method as described above is executed for one or more discrimination items, and the presence or absence of a contradiction in the character information can be discriminated from the result. When discrimination is performed for multiple discrimination items, for example, when it is determined that there is no contradiction for all discrimination items, the driver's license 10 can be determined to be genuine.
[0057] As described above, in this embodiment, the authenticity of the driver's license 10 is determined by comparing the IC chip information with the character information on the face of the driver's license 10 and determining whether there is a contradiction in the character information on the face of the driver's license 10. By determining the authenticity based on these results, the authenticity of the driver's license 10 can be determined more reliably.
[0058] The character information used for authenticity determination indicates, for example, a specific date, and the authenticity of the driver's license 10 can be suitably determined based on whether the content of the information matches the IC chip information or whether there is a contradiction. Inconsistencies in character information can be broadly divided into cases where there is a contradiction between the content of one piece of character information and the content of another piece of character information, and cases where there is a contradiction between the content of one piece of character information and the attributes of that piece of character information, and both cases can be determined as contradictions in this embodiment.
[0059] Furthermore, in this embodiment, if the IC chip of the driver's license 10 cannot be read, the possibility that the driver's license 10 is genuine simply because the IC chip is broken is taken into consideration, and the driver's license 10 is not deemed to be genuine simply because the IC chip cannot be read, but the authenticity can be determined by also taking into consideration whether there are any inconsistencies in the text information on the face of the card.
[0060] Furthermore, the authenticity determination device 3 can make a more reliable determination by determining that the driver's license 10 is not genuine if a negative result is obtained by either comparing the character information on the face of the license with the information on the IC chip, or by determining whether or not there is a contradiction in the character information on the face of the license.
[0061] In addition, in this embodiment, the IC chip information used for matching is information that can be read without entering a personal identification number (PIN), so that there is no need to enter a PIN to read the IC chip information, simplifying the authenticity determination process.
[0062] However, the present invention is not limited to the above-described embodiment. For example, the character information used to determine the presence or absence of a contradiction is not limited to the above-described one, and character information indicating specific locations, such as the address 13 and the public safety commission 18, can be compared to determine whether or not there is a contradiction between the contents. In this case, for example, if the address 13 is forged and the prefecture of the address 13 obtained from the face image does not match the prefecture of the public safety commission 18, it is determined that there is a contradiction.
[0063] It is also possible to use IC chip information used for verification that can be read by entering a PIN. In this case, however, it is necessary to enter the PIN during the authenticity determination process, which is time-consuming.
[0064] Although the preferred embodiment of the present invention has been described above with reference to the accompanying drawings, the present invention is not limited to the above examples. It is clear that a person skilled in the art can come up with various modified or altered examples within the scope of the technical ideas disclosed in this application, and it is understood that these also naturally belong to the technical scope of the present invention.
