Description

{Secrimination method and apparatus for forgery of wertpapier, and Recording medium}

The present invention relates to a system using a two-dimensional bar code, and more particularly, to a method, apparatus, and a recording medium for securities authenticity determination.

Checks are securities in which the issuer consigns a fixed amount of payments to the payer (financial institution) to the recipient or other legitimate holder. The check is a means of securitizing the bonds together with the draft to ensure repayment of the bonds and to facilitate the circulation of the bonds. .

A check issued by a financial institution in Korea records the amount, payment address, issue place, issue number, and date of year. These data are recorded at the bottom of the check ticket in magnetic letters in dotted lines. On the other hand, bank stores are equipped with machines that process these checks in batches. A bank store prepares a check before starting work with this machine.In the case of a flat ticket, the headquarters receives a check ticket printed with only the amount and the check number.The branch name, the branch manager's name and the ticket type, amount, payment address, issue place and issue number Print a large number of basic information such as checks and, in the case of non-scheduled bills, input the amount into the input device of the machine and print it like a flat ticket or prepare to print the amount through a transaction.

Now, when a customer who visits a financial institution requests a check issuance, the employee of the financial institution calls the check transaction screen on the teller terminal device and inputs the check number of the check prepared before the start of the operation. The check issuance service is processed by inputting in the input field. If there are many checks, only the serial number and the number of copies can be entered to process the check issuance service.

On the other hand, when a customer who visits a financial institution requests a check receiving service, a worker calls a transaction screen from a remote terminal device, and in the case of a self-checked check, enters a check number and issuing point to process a check receiving service and receives the received check. Seals the seal 'PAID' and keeps it for 10 years in our vault. In the case of other checks, on the check transaction screen, check only the amount of money as the other check distinction value, and simply enter the total amount to process the check collection service.After the closing of the bank window, the other checks received from the customer are sent to the microfilm machine. After taking two-sided pictures, the checks are physically transferred to the current funding department for payment and bill exchange.The funding department separates the checks for each bank using a check sorting machine, and then transfers them to the financial settlement agency. In addition, the checks collected at the KFTC will be cashed for each bank.

To prevent counterfeit checks are self-printed with ink containing magnetic ingredients to prevent counterfeit money. When counting checks, an ink containing chromium oxide (CrO3) is added to the ink printed on the surface to use the principle that the resistance changes when a magnetic field is applied.

It can be seen that the magnetoresistance occurs only where the ink containing chromium oxide is applied, so there is no magnetoresistance reaction, even if there is a reaction, the reaction occurs at an unspecified position, or the exact response waveform does not occur at a specific position, Or determine the maximum value from the ratio using magnetic tape or iron powder to determine whether it is a counterfeit currency or a pneumococcal.

Check the authenticity of the check through the resistance value according to the specific material contained in the ink as described above. There is no way to do it.

The first technical problem of the present invention is to provide a securities authenticity determination method which is not vulnerable to the determination of copied securities while easily determining the authenticity of securities anytime and anywhere.

A second technical problem to be achieved by the present invention is to provide a recording medium that can be read by a computer system as a medium on which a program for executing the security authenticity determination method in a computer system is recorded.

The securities authenticity determination device 110 accesses the financial settlement source server 130 through the mobile communication network 121 such as the base station 120 and inquires the serial number in the securities database 131.

When the securities authenticity determination device 110 displays the serial number in the securities database 131, information about the authenticity of the securities 100 is displayed on the screen 112.

The financial settlement server 130 stores the information of the two-dimensional barcode printed on the security 100 in the security database 131 or the like. The security database 131 may store the contents of the security, such as a check issued.

2 is a block diagram of an apparatus for determining authenticity of securities according to an embodiment of the present invention.

In the following, it is assumed that a two-dimensional bar code representing the serial number of the security is printed on the surface of the security. Here, the securities may be checks, bonds, securities, insurance policies, payment certificates, gift certificates, and the like.

The digital camera 210 obtains a barcode image by photographing a two-dimensional barcode printed on the security. The digital camera 210 includes a CCD image sensor or a CMOS image sensor.

The barcode inspection unit 220 directly receives a barcode image of the digital camera 210 and the digital camera 210 or reads a barcode image stored in the memory 230. The barcode inspecting unit 220 determines whether the security is counterfeit by inspecting the brightness values of the color and background color of the black cell in the barcode image. Here, black cells refer to black dots displayed on a white (or gray) background in order to image information in a bar code form. The barcode inspection unit 220 inspects the two-dimensional barcode to obtain a serial number by reading the barcode image when the security is not counterfeit.

In another embodiment of the present invention, when two or more two-dimensional barcodes representing the serial number of the security is printed on the surface of the security, two or more barcode images may be obtained through the digital camera 210. In this case, when the barcode image includes both a black two-dimensional barcode and a gray two-dimensional barcode in the barcode image, the barcode inspection unit 220 determines that the securities are not forgery, and reads the barcode image to obtain a serial number.

The memory 230 stores a barcode image obtained by the digital camera or a serial number obtained by the barcode inspection unit 220. The memory 230 may be a volatile memory such as a DRAM, but a nonvolatile memory may be used as necessary.

The wireless communication unit 240 accesses the financial settlement server through the mobile communication network and inquires the serial number stored in the memory in the security database.

When the serial number is inquired in the security database, the verification unit 250 displays information on the authenticity of the security on the display panel 260.

As an example of the display panel 260, a liquid crystal display (LCD) panel may be used. The display panel 260 may include a graphics processor for screen display.

Table 1 shows an example of a bar code format when the two-dimensional bar code is used for a gift certificate or a ticket.

division Item Contents Byte Remarks One Individual Approval Number Mobile phone approval key 5 2 Read Password Key Read Required Key 10 3 Product Code Classification name or code / amount for a product name 40 4 Account1 Issuer's Account 14 5 Account2 Recipient's Account 14 None [null] 6 First issuer Business name 20 7 First issuer Mobile Phone Number 15 8 One-time recipient name 20 9 One-time recipient Mobile Phone Number 15 sum 153

If the security is a voucher or ticket, when the customer selects the voucher on the website and pays the amount of the voucher to be purchased, the two-dimensional barcode of the above format is encrypted and printed on the voucher, printed on the actual voucher / ticket or by mobile phone. Once downloaded, it can be used for payment.

When a user of a gift certificate is presented, he or she can read it with the registered owner's registered mobile phone or a dedicated reader (securities authenticity determination device), and then transfer the amount of the product to the registered owner's account. If you have a gift certificate in the form of a two-dimensional barcode on your mobile phone, read the barcode displayed on the screen of the mobile phone with the store owner's mobile phone or a dedicated reader (securities authenticity determination device), check the transfer amount, and send the approval number to the customer. Can be used.

3 is a flowchart illustrating a method of determining authenticity of securities according to an embodiment of the present invention.

First, a two-dimensional barcode of the security is photographed with a digital camera embedded in the mobile terminal to obtain a barcode image (S310).

Next, by checking the brightness value of the color and the background color of the black cell in the barcode image to determine whether the security of the forgery (S320).

As a result of the determination, if the security is not a counterfeit (S330), the serial number is obtained / confirmed by reading a barcode image (S340). If the security is counterfeit (S330), it indicates that the security is counterfeit on the screen of the portable terminal and the procedure ends.

When the serial number is read, the mobile terminal accesses the financial settlement server through the mobile communication network and inquires the serial number in the security database (S350).

If the serial number inquiry is successful (S360), the portable terminal displays information on the authenticity of the security on the screen (S370). If the serial number lookup fails (S360), the portable terminal terminates the authentication process of the security or displays an error message or the like on the screen.

In another embodiment of the present invention, if the inquiry of the serial number is successful, the settlement process using the security may be performed. This process includes reading a bar code image to read account information and amount information, and a mobile terminal accessing the bank network and transferring cash according to the amount information using the account information.

FIG. 4A illustrates an example of an authentication process using a mobile phone approval key in the serial number reading process (S340) of FIG. 3.

First, the mobile terminal reads the barcode image and reads out the mobile phone approval key (S441).

Next, it is determined whether the read cellular phone approval key matches the secret key preset in the portable terminal (S442).

At this time, if the mobile phone approval key does not match the secret key (S442), the mobile terminal rejects the authentication and displays a message to reject the authentication (S444). On the other hand, if the mobile phone approval key matches the secret key (S442), the authentication message is displayed on the screen of the mobile terminal (S445).

In another embodiment of the present invention, the unique secret key of the mobile phone may be stored in an external storage such as a financial settlement server. In this case, the mobile terminal can proceed with the authentication procedure by transmitting the mobile phone approval key to an external server.

FIG. 4B illustrates an example of an authentication process using a read encryption key in the SSS server access and inquiry process (S350) of FIG. 3.

Before the portable terminal connects to the financial settlement server, the barcode image is read and the read encryption key is read (S451).

Next, access to the financial settlement server to determine whether the read encryption key and the encryption key stored in the financial settlement server (S452).

If the readout encryption key does not match the encryption key of the financial settlement server, and authentication fails (S453), the portable terminal rejects the authentication and displays a message for rejecting the authentication (S454). On the other hand, if authentication is successful, the mobile terminal displays an authentication message on the screen.

5 is a flowchart of a securities authenticity determination method according to another embodiment of the present invention.

First, a bar code image is obtained by photographing two-dimensional barcodes of the security with a digital camera embedded in the mobile terminal (S510).

Next, it is checked whether a black two-dimensional barcode and a gray two-dimensional barcode are included in the barcode image (S520). Here, the black two-dimensional barcode and the gray two-dimensional barcode are distinguished by the brightness difference between the two. Black two-dimensional barcodes have lower brightness than gray two-dimensional barcodes.

When the barcode image includes the black two-dimensional barcode and the gray two-dimensional barcode, it is determined that the double barcode is printed on the security (S530), and the serial number is read from the barcode image (S540). If the double bar code is not printed on the security (S530), it indicates that the security is counterfeit on the screen of the portable terminal and ends the procedure.

When the serial number is read, the mobile terminal accesses the financial settlement server through the mobile communication network and inquires the serial number in the security database (S550).

If the serial number inquiry is successful (S560), the portable terminal displays information on the authenticity of the security on the screen (S570). If the serial number lookup fails (S560), the portable terminal terminates the authentication process of the security or displays an error message or the like on the screen.

In another embodiment of the present invention, if the inquiry of the serial number is successful, the settlement process using the security may be performed. This process includes reading a bar code image to read account information and amount information, and a mobile terminal accessing the bank network and transferring cash according to the amount information using the account information.

6A, 6B, 7 and 8 illustrate an example of performing a brightness value checking process S520 of the barcode of FIG. 3.

As shown in FIG. 6A, the portable terminal may examine a change in the concentration of the black cell to determine whether the security is forged.

If the two-dimensional barcode is in the form of black cells (black cells printed with the brightness of the first brightness value) printed in gray on the surface of the security, there is a difference between the brightness of the black cells and the background color in the barcode image taken by the mobile terminal. If it is above the second brightness value, it can be determined that the security is not a counterfeit. If the first first brightness value is appropriately adjusted to print a two-dimensional bar code, the second brightness value for copy protection can be determined.

FIG. 6B shows a threshold value at which scanning becomes impossible, that is, a second brightness value at which a security is forged.

7 shows an example in which the brightness value of the cross (+) area in the center of the two-dimensional barcode is increased and printed.

In FIG. 7, the brightness of the entire black cell is 70, but the brightness of the center cross (+) region is 100. In FIG. In this case, if the difference between the brightness of the entire black cell and the brightness of the cross (+) area in the center decreases or increases, it may be determined that the security is counterfeit. That is, when a specific area of the barcode image includes gray cells having brightness greater than or equal to the third brightness value, it may be determined that the security is not a counterfeit. Here, the third brightness value is a value that can be determined by repeated experiments.

8 shows an example of determining whether a forgery is generated when the background color of the two-dimensional barcode is gray.

Such two-dimensional barcodes appear to be white due to the increase in the brightness of the background color during copying. If the brightness of the background color excluding the black cells in the barcode image is less than the threshold value, it can be determined that the security is not a counterfeit. In this case, the threshold value is a brightness value that can be used as a reference for distinguishing gray from white color with the naked eye.

An example of a method of manufacturing a two-dimensional bar code with a gray background color may include printing black black cells on a security and attaching a gray translucent sticker thereon.

9 illustrates an example of performing the double bar code inspection process S520 of FIG. 5.

An example of a method of manufacturing a double barcode may be a method of printing black black cells on a security, and then attaching a transparent sticker printed with a gray two-dimensional barcode on the securities. The two barcodes may be arranged side by side as shown in FIG. 9 or may be arranged such that certain portions overlap each other. As a result of photographing on a portable terminal or a dedicated reader (securities authenticity determination device), if two two-dimensional barcodes are not seen, it can be determined as a copy.

The invention can be implemented via software. Preferably, a program for executing the security authenticity determination method according to embodiments of the present invention may be provided by recording a program for executing in a computer on a computer-readable recording medium. When implemented in software, the constituent means of the present invention are code segments that perform the necessary work.
