An Authentication Method Of A Teasted Copy Using Two Dimensional Bar Code}

The present invention relates to an authentication method for preventing forgery and tampering of a certified copy of a register, and more particularly, by printing a two-dimensional bar code on a certified copy and allowing a separate authentication server to authenticate the contents of the two-dimensional bar code. And it relates to an authentication method of registered copies using a two-dimensional bar code that can prevent tampering.

1 is an explanatory diagram schematically illustrating an application example of the PDF417 10 in a two-dimensional bar code. As shown in FIG. 1, two-dimensional barcodes can be broadly divided into stacked bar codes and matrix codes. In the present invention, the PDF 417 method is used. The PDF 417 method is a multi-layered barcode with variable symbol length and height. PDF 417 may contain up to 1350 ASCII characters, 1108 bytes, or 2710 numbers (if error detection is zero), depending on the presentation format of the data. That is, it can contain a large amount of data, and has a function of detecting and correcting data errors, which makes it suitable as a portable data file and can be read by a conventional linear laser scanner, raster laser scanner, linear CCD scanner, and 2D CCD scanner.

Application examples of the PDF417 10 include voice information, binarization data, text information, photo or image information, palm rest information, signature information, fingerprint information, and the like. In other words, the information can be converted into a two-dimensional bar code of the PDF417 (10) and printed (output) or scanned (read) and reproduced.

Registered copies issued by court registers are public documents widely used in bank loans, mortgages, and guarantees. Such registered copies are particularly likely to be subject to crime, forgery, or forgery, as they represent documents representing large amounts of real estate.

Reflecting this, the issue number is written at the bottom of the current register copy, but this is only for the recognition of the registered copy and the convenience of data input. Thus, these publication numbers were easy to forge or alter through copying, pasting, overwriting, scanning, and graphics.

Therefore, there is a growing demand for the development of a more secure security system to address these risks.

Accordingly, the present invention has been made to solve the above problems, an object of the present invention is to print a two-dimensional bar code containing a large amount of information on a certified copy of the two-dimensional bar code that can prevent forgery and tampering It relates to an authentication method of registered copy using.

As shown in Fig. 2, the registered copy 20 (for example, the real estate register copy) is an official document issued by the registry register of the court and is a document for indicating the legal relationship of the real estate.

The publication number 22 is written at the bottom of the registered copy 20, and Arabic numerals and alpha-pets are mixed according to a predetermined method, and used as needed within a total of 60 to 90 digits. In Fig. 2, a 73-digit publication number 22 is described.

The two-dimensional bar code 30 is produced by the PDF417 method and is printed on the side of the issue number 22 among the lower ends of the registered copy 20. The two-dimensional bar code 30 includes the contents of the publication number 22 encrypted, and includes the contents of the registered copy. For example, the inside of the two-dimensional bar code 30, the issue number (22), the pressurized water setting items, the basis of each basis setting, the amount of information, the issue date (2002.03.20), the unique number (1164-1996-748660), Includes information on the owner, etc. Since the 925 codewords or 1850 ASCII characters can be input in the two-dimensional barcode 30 of the PDF417 type, there is no problem in including the data related to the registered copy.

3 is a system configuration diagram for implementing a method of authenticating a registered copy using a two-dimensional barcode according to the present invention. As shown in FIG. 3, at least the authentication server 42, the issuer computer 44, and the loan agency computer 46 are connected to the Internet 40.

The issuing authority computer 44 has a configuration in which it is possible to issue an issued copy of the registered copy 20 and to transmit data about the issued copy of the registered copy 20 to the authentication server 42 via the Internet 40.

The authentication server 42 receives data on the registered copy 30 from the issuing agency computer 44 through the Internet 40, receives the contents of the barcode read from the lending institution computer 46, and receives the password. After solving, the structure is configured to determine whether or not the same by cross-checking each other, and whether or not authentication is transmitted to the lender institution computer 46 according to the determination.

To this end, a database server (not shown) capable of storing and retrieving data received with respect to the registered copy 20 in the authentication server 42 and configured or embedded therein, and an encrypted two-dimensional barcode 30 The inverse encryption algorithm that can solve the contents of and recover the issue number 22 is built in. In addition, the database table of member data for member management, the billing database table for billing, the e-mail server for e-mail, the SQL server for searching, and the www server for operating the homepage are separately configured or embedded.

The lending institution computer 46 may transmit the contents of the two-dimensional barcode 30 read through the Internet 40, receive an authentication result, and a separate registered copy reader 50 is connected. A detailed configuration of such a reader 50 will be described later in the description of FIG. 4.

The loan institution computer 46 receives the reading result of the two-dimensional bar code 30 from the connected reader 50, and controls the operation, stop, and the like of the reader 50.

As shown in FIG. 5, this window 60 is displayed on the issuer computer 44.

The issue number 22 is 73 characters and is automatically generated according to a predetermined algorithm. When the contents of the publication number 22 are read by the naked eye, their meaning is unknown.

The encrypted issue number data 63 is data which is enciphered with the random number table by encrypting the issue number 22 in a predetermined manner. In the present invention, the issue number 22 is 73 digits, and the encrypted issue number data 63 is 146 digits. The detailed algorithm of encryption will be omitted.

The "Encryption + 2-D Barcode Generation" button 65 is a button for displaying the encrypted issue number data 63 and the 2-D barcode 30 on a monitor (not shown). Accordingly, when the "Encryption + 2D barcode generation" button 65 is pressed while the issue number 22 is generated, the encrypted issue number data 63 is generated, and the 2D barcode 30 including the issue number 22 is monitored ( (Not shown).

The "register copy output" button 67 has a configuration for transmitting a print command to an actual printer (not shown).

Hereinafter will be described in detail the authentication method of the registered copy using a two-dimensional barcode according to the present invention having the configuration as described above. This description will be described by dividing the register copy issuance step of FIG. 6 and the register copy authentication method of FIG. 7.

First, FIG. 6 is a flowchart illustrating an issuing step of a registered copy using a two-dimensional barcode according to the present invention. As shown in FIG. 6, the applicant applies for issuance of a certified copy of registration for a specific real estate (for example, Rainbow Apartment Building 4, 401) online or offline to the issuing organization (for example, a registry) (S10). .

Then, the person in charge of the issuing organization prepares the issuance of the registered copy 20 by inputting the address relating to the specific real estate in the issuing agency computer 44. Then, the issuing authority computer 44 reads the data on the registered copy 20 according to the command, and generates the issue number 22 of the registered copy 20 as shown in FIG. 5 (S12).

The person in charge of the issuer who visually confirmed this presses the "Encrypted Issue Number Data" button 65. Then, the issuing authority computer 44 encrypts the issuing number 22 in a predetermined manner to generate the encrypted issuing number data 63 (S14).

Next, the encrypted issue number data 63 is converted into a two-dimensional barcode 30 of the PDF417 type and displayed (S16).

Then, when the person in charge presses the "register copy output" button 67, the registration copy 20 is printed, and the issue number 22 and the two-dimensional barcode 30 are printed together at the bottom of the register copy 20. (S18). The registered copy 20 thus printed is handed to the applicant.

Then, the issuer computer 44 connects to the authentication server 42 via the Internet 40, and then transmits and stores the issue number 22 to the authentication server 42 (S22). Through this process, the issuance process of the registered copy 20 is completed.

7 is a flowchart illustrating a method of authenticating a registered copy using a two-dimensional barcode issued by FIG. 6. As shown in FIG. 7, the applicant submits the registered copy of the issued registration to a lender such as a financial institution (S30).

Then, the employee at the window of the lending institution puts the submitted registered copy 20 into the reader 50 for reading. When the registered copy 20 is input, the scanner 57 detects this and reads the two-dimensional bar code 30 (S32). The read data is transmitted to the loan institution computer 46, and the loan agency computer 46 transmits the read data to the authentication server 42 via the Internet 40 (S34).

Next, the authentication server 42 reverses the cipher of the read data to generate data, and compares the generated data with the issued number 22 received from the issuing authority computer 44 (S36).

As a result of the comparison, if the decrypted data and the issue number 22 are the same, the authentication server 42 transmits the authentication confirmation data to the lender institution computer 46. By the way, if the decrypted data and the issue number 22 are not the same or if the password cannot be decrypted, the non-authentication data is transmitted to the lending institution computer 46 (S38).

Therefore, the lending institution computer 46 can determine whether the registered copy submitted is authentic through the receipt of the authentication confirmation data or the non-authentication data from the authentication server 42.

Then, the authentication server 42 transmits the authentication result to the lending institution computer 46, and then charges data according to the number of times of authentication from the authentication server 42 to the lending institution computer 46 (for example, 23 times * 200 won / time = 4,600 won) (S40).

The authentication method of the registered copy using the two-dimensional bar code according to the present invention can be implemented as a program code executable by a computer, such program code is a hard disk, floppy disk, compact disk, memory stick, magneto-optical disk, mini disk It can be implemented to be stored in a recording medium such as a DVD, a digital tape, a memory chip, a flash memory, and the like to be read by a computer.

In the present invention, a registered copy is issued directly in the form of a paper, and the applicant shows and explains it in the form of submitting it directly to the lender, but the registered copy completed according to the present invention is an image file (for example, BMP, GIF, JPG). , TIFF format) may be transmitted to an e-mail address designated by the applicant, and then may be determined to be authenticated through the image file attached to the e-mail received from the lender computer 46.

In the present invention, although the registered copy of the register is illustrated and described as a representative example, the present invention is not limited thereto, but may be applied to an application for admission, a graduate application, a driver's license application, and the like. In addition, it can be applied to a tax invoice, transaction statement, additional tax return, income tax return, national health insurance claim, insurance policy, national health insurance application, industrial accident compensation insurance application, employment insurance application, national pension application, government complaints application, etc.

Other construction-related documents (including construction performance reports, etc.), various financial documents (bank deposit slips, withdrawal slips, alternative slips, etc.), and jiro slips (all OCR slips, construction billing OCR slips, and apartment management fee slips). It can be widely used.

According to the authentication method of the registered copy using the two-dimensional bar code according to the present invention as described above, even if the contents of the issued number or the barcode is altered, cut or pasted into another or deleted through the computer, the authentication server 42 is the issuing authority computer ( Since it is determined whether or not to be authenticated based on the data transmitted from 44, it is possible to immediately know whether the forgery or tamper is made through the lender's computer 46.

Therefore, even if a certified copy is used for a crime such as a loan fraud, it can be blocked at an early stage. As a result, the reliability of the registered copy is increased, and there is an advantage that civil complaints can be used with confidence.

Although the present invention has been described in connection with the above-mentioned preferred embodiments, it is possible to make various modifications or variations without departing from the spirit and scope of the invention.
