1 is a simplified diagram illustrating the principles of the present invention.

The present invention is carried out by examining the identification of forgery of three stages.

In the first step, the identification information written on the identification card 1 is checked. After the identification card 1 is photographed by a camera, an OCR (Optical Character Reader) process is performed. The identification information is determined based on the acquired identification information, and the validity of the social security number is determined.

2 is a view showing an identification card forgery determination apparatus according to a first embodiment of the present invention.

ID card forgery determination device 100 of the present invention shown in the ID card 10, the photosensor 20, the image pickup unit 30, the infrared detector 40, the ultraviolet detector 50, the OCR processor 35 ), A first A / D converter 45, a second A / D converter 55, a controller 60, and a database 70.

First, when the ID card is inserted into the ID card opening 10, the photo sensor 20 detects the ID card input, and the controller 60 drives the image capturing unit 30. At this time, the identification card is transferred by a motor (not shown). The image capturing unit 30 includes a camera 31 and an illumination lamp 32.

The camera 31 is a CCD camera for acquiring the image data of the inputted ID card, and the lighting lamp 32 is an illumination lamp such as a light emitting diode (LED).

The image data acquired by the image capturing unit 30 performs OCR processing by the OCR processing unit 35. The OCR processing unit 35 extracts a name, resident registration number, address, issue date, and issuer in the case of a resident registration card and stores it in the database 70.

The controller 60 drives the image capturing unit 30, the infrared sensing unit 40, and the ultraviolet sensing unit 50, and determines whether the ID card is forged based on the information obtained from the ID card.

The control unit 60 includes an identification card determination unit 61, a social security number determination unit 62, an infrared forgery determination unit 63, and an ultraviolet forgery determination unit 64.

The identification card determination unit 61 first determines that the card is a resident registration card through the letter “resident registration card” displayed on the identification card among the data read by the OCT processing unit 35.

If it is difficult to judge due to the damage and damage of the resident registration card, it is determined by comparing the identification information stored in the database 70 second.

Identification information is information stored in each identification card, such as national ID card, driver's license, disabled welfare card, national merit card, and independent merit card.

The identification card determination unit 61 compares the data constituting the identification card read by the OCR processing unit 35 with the identification card information stored in the database 70 to determine the type of identification card.

In addition, since the resident registration number determination information based on the resident registration number generation logic is stored in the database 70, the resident registration number determination unit 62 of the control unit 60 validates the validity of the resident registration number obtained by the OCR processing unit 35 based on the resident registration number identification information. To judge.

After determining the resident registration number in the resident registration number determination unit 62, the identification card is transferred to the infrared detection unit 40 by the motor.

The infrared detector 40 includes an infrared lamp 41 and an infrared light receiver 42, and detects the transmission value of the infrared light to determine whether the forgery exists.

The infrared lamp 41 irradiates the identification card with infrared light, and the transmitted amount of infrared light received by the infrared light receiving part 42 passes through the first A / D conversion part 45 and is converted into a transmission value.

Identification cards are forged by making color copies, changing the photo of the identification card, and changing the social security number. Therefore, the forged ID card changes the infrared transmittance of the ID card by changing the material of all or part of the ID card such as copying or changing or overwriting the ID card. That is, the present invention is characterized by discriminating forgery and identification of identification cards by focusing on the transmission function of infrared rays, among other various characteristics of infrared rays.

The infrared detection unit 40 determines the forgery by the difference in the carbon ratio between the overlaid ink and the existing ink by using the property of infrared rays that are absorbed more as the carbon is more contained.

The infrared forgery determination unit 63 of the controller 60 compares the standard transmission value for each identification card stored in the database 70 with the transmission value detected by the infrared detection unit 40 to determine whether the forgery is performed.

Then, the ID card is moved to the UV detection unit 50 to determine whether the forgery through the ultraviolet light.

In general, identification cards are fabricated by embedding fluorescent materials that appear during ultraviolet transmission. These fluorescent materials do not appear in normal visible light, but appear when ultraviolet light is irradiated. It uses the properties of ultraviolet light to cause chemical reactions with materials.

The ultraviolet detector 50 includes an ultraviolet lamp 51 and an ultraviolet light receiver 52, and detects a reflection value of ultraviolet rays to determine whether the forgery exists.

The ultraviolet lamp 51 irradiates the ID card with ultraviolet rays, and the ultraviolet light receiving unit 52 measures the wavelength of light reflected on the ID card surface of the irradiated ultraviolet rays. This value passes through the second A / D conversion unit 55 and is converted into a reflection value.

The UV counterfeit determination unit 64 of the control unit 60 compares the standard reflection value for each ID card stored in the database 70 with the reflection value detected by the UV detection unit 50 to determine whether the forgery is performed.

As described above, the identification forgery and forgery determining apparatus 100 according to the present invention discriminates based on the validity of the social security number, the transmission value of the infrared ray, and the reflection value of the ultraviolet ray.

The sequence described in FIG. 2 is merely an example for clarity of understanding, and the present invention can operate regardless of the order, and can arbitrarily manipulate the sequence or perform only necessary processes.

FIG. 3 is a diagram illustrating the function of the database shown in FIG. 2.

The database 70 includes an identification card information DB 71, a social security number identification DB 72, an infrared ray transmission value DB 73 for each identification card, and an ultraviolet reflection value DB 74 for each identification card.

The identification card information DB 71 is used to determine the type of identification card using the information stored in the resident registration card, the driver's license, the welfare card for the disabled, and the national ID card, and the arrangement information.

For example, a driver's license specifies the driver's license number, name, address, and aptitude test period. Then, the driver's license number read by the OCR processing unit is configured as the area name AB-CDEFGH-IJ, and thus, the driver's license number of the driver's license is read out that the ID is a driver's license.

Similarly, in the case of independence and national merit certificate, the veteran number is specified so that it can be distinguished by the veteran's number.

The resident registration number determination DB 72 stores an algorithm for determining the validity of the resident registration number using the resident registration number read by the OCR processor.

The social security number consists of the first six digits and the last seven digits of the social security number, indicating the year, month and day of birth.

If 790101-abcdefg, a indicates gender and date of birth, followed by bcde indicates the region (city, state, ward / county, town, town, dong) where the social security number is registered.

The next f is the serial number of the day's birth notification in that order in the bcde area, and usually does not exceed 1,2,3 because there are not so many newborns born per day in the bcde 4-digit combination.

The last g is a number that checks if the social security number is correct. Based on this algorithm, the validity of the social security number is determined.

Infrared transmission value DB for each identification card 73 stores the infrared transmission value of each identification card for each identification card.

The ultraviolet transmission value DB 74 for each identification card stores the reflection value of the reflected wavelength by the ultraviolet lamp of the material constituting the surface of each identification card for each identification card.

4 is a diagram illustrating a process according to a second embodiment of the present invention.

First, the ID card is inserted into the ID card slot (S1010). In order to determine the type of identification card, the illumination lamp is driven (S1020), and the camera is operated (S1030).

Image data is acquired (S1040), and OCR processing (S1050) is performed. The type of identification card is determined based on the information obtained through the OCR process and the content stored in the identification card information DB (S1060).

Companies, banks, and government offices that keep separate copies of their IDs will automatically save the image data they have obtained, saving you the trouble of preparing a copy of your ID.

In addition, since information obtained through OCR processing is automatically stored in a database, an input process for inputting personal information is unnecessary.

The user selects a menu for the necessary inspection (S1070).

When the user selects the "resident registration number check" (S1100), the validity of the resident registration number is determined based on the contents stored in the resident registration number determination DB (S1110).

After determining whether it is valid (S1120), if it is valid, the display device displays "valid social security number" (S1140).

If it is not valid, the display shows "Invalid Social Security Number. Please perform another check or contact the police."

When the user selects "infrared inspection" (S1200), the infrared lamp is irradiated on the identification card (S1210).

The transmittance is extracted from the infrared light receiving unit (S1220), and after the A / D conversion, the detected transmission value is compared with the transmission value of the corresponding ID stored in the infrared transmission value DB for each ID (S1230).

After determining whether it matches (S1240), if it matches, it displays on the display device, "It is an ID that is not forged as a result of an infrared test" (S1250).

If it does not match, display on the display device "Possible identity card, please perform another check or contact the police station" (S1260).

If the user selects "ultraviolet test" (S1300), the UV lamp is irradiated to the ID card (S1310).

The reflectance is extracted from the ultraviolet light receiver (S1320), and after the A / D conversion, the detected reflection value is compared with the reflection value of the corresponding ID stored in the ultraviolet reflection value DB for each ID (S1330).

After determining whether it matches (S1340), if it matches, the display device displays "Ultraviolet test result that the ID is not forged" (S1350).

If it does not match, display on the display device "Possible forgery identification card other check or contact the police station" (S1360).

The present invention is helpful in crime prevention because the image data of the forgery identification card, and the information is automatically transmitted to the police server.

The ID card forgery determination system 500 further includes an ID card forgery determination apparatus 200, and a real name verification server 300, according to a basic configuration or need, for an identity inquiry server 400.

Identification card forgery forgery determination system 500 transmits the resident registration number and name of the identification card acquired by identification card forgery and forgery determination apparatus 200 to perform real name authentication.

In addition, when the identification card inputted to the identification forgery forgery identification device 200 is a driver's license, a national merit certificate, and an independent man's ID card, identity verification is possible in the identity inquiry server 300 with a driver's license registration number and veteran's number.

Therefore, in the case of an adult entrance area and a company that sells items that cannot be purchased, juveniles may change the digit of the resident registration number. Therefore, the counterfeit ID card, the real name verification, and the identity inquiry may be selectively performed to determine whether the ID card is forged. Can be.
