Description

Authentication system using divided bar-code}

The present invention relates to an authentication system using a barcode, and in particular, to divide a barcode stored with first authentication information corresponding to a subject requesting authentication in a transaction requiring authentication, to issue a first divided barcode, and to issue the first divided barcode. An authentication system using a split bar code that performs the requested authentication by determining whether a bar code including the authentication information is matched by combining with a second split bar code in which second authentication information corresponding to a subject having a common area among bar codes is stored. It is about.

In general, a barcode is an optically readable encoding of letters, numbers, symbols, etc. through a combination of black bars and white bars in between, which facilitates data input and data processing. The system can be configured and widely used in various fields.

However, the information encoded by the one-dimensional barcode as described above is represented only by the bar and the width of the space extending in a single dimension. Since all bars and blanks have a uniform height in their vertical direction, the information is stored only in the horizontal direction of the one-dimensional barcode. Therefore, only a limited amount of data can be recorded because data must be recorded within a certain width.

Recently, as the demand for information technology increases, there is an increasing demand for removing associated databases and storing more information in the code itself. As a result of this demand, two-dimensional barcodes have emerged as an extension of one-dimensional barcodes since the mid-1980s. The two-dimensional bar code is a flattened array of data on both axes (x-axis direction, y-axis direction), which expands the problem of one-dimensional barcode, that is, the limitation of data representation. Such two-dimensional barcodes can generally be classified into two categories. That is, one is a stacked bar code, and another one-dimensional bar code is provided on the top of the one-dimensional bar code, and the other is a matrix bar code, which is designed as a true two-dimensional matrix.

The use of such barcodes is mainly used for tickets, coupons, etc. as a method of writing information on a product so that the information of the product can be confirmed, photographed with a digital camera, displayed on a screen, or printing a received barcode.

However, due to the easy tampering of the bar code, the application is not limited or used in security-critical areas. In order to partially solve this problem, each time a barcode containing the information of a cash card or membership card that requires repeated use is accessed and downloaded and used every time through the Internet, it still contains a vulnerability to security.

In addition, in order to increase the security in the e-commerce using a bar code, OTP (One Time Password) code can be generated and used as a bar code. The required personal information is inconvenient to be input by the user separately.

Therefore, the present invention has been made in order to solve the above problems, by issuing a first divided bar code by dividing a bar code stored in the first authentication information corresponding to the subject to request authentication in a transaction requiring authentication, and issued Enhanced security against illegal copying and forgery of barcodes by reading the barcodes to perform the requested authentication by combining with the second divided barcodes in which second authentication information corresponding to the subject having a common area among the first divided barcodes is stored. The purpose of the present invention is to provide an authentication system using a split bar code that can improve gender.

It consists of another 3rd area | region 330 with the 2nd area | region 320b which shows a division | segmentation barcode common to one division | segmentation barcode. At this time, the second area is formed of the same code by overlapping the second area 320a of the first divided bar code and the second area 320b of the second divided bar code as shown in FIG. 2A, or as shown in FIG. 2B. The second area 320a of the divided bar code and the second area 320b of the second divided bar code are cut based on the cut surface of the pattern corresponding to each other, so that the second area 320a and the second divided bar code of the first divided bar code are divided. The second region 320b may be formed of different codes in which regions opposite to each other are removed based on the cut surface.

When the authenticator 300 receives an authentication request from the subject, the authenticator 300 may access the second regions 320a and 320b which are common to the first divided barcode and the second divided barcode. Authentication of the subject is performed through complete barcodes generated in a manner that is coupled to each other.

In this case, in the case of the first divided barcode and the second divided barcode having the structure of FIG. 2A, the second region 320 may be combined in the authentication unit 300, as shown in FIG. 3.

The first divided barcode and the second divided barcode are combined with each other.

In this manner, the second regions 320a and 320b which are the common regions of the first divided barcode and the second divided barcode are generated in such a manner as to overlap or interlock with each other, and then the first region 310 of the first divided barcode is generated. And the third region 330 of the second divided barcode are combined together to form a complete barcode as shown in FIGS. 3 and 4.

The first divided barcode and the second divided barcode are issued in advance by a third party such as an authenticator or a social service manager, and the first authentication kit 100 includes a plastic card type on which the first divided barcode is printed or It consists of a paper card type.

On the other hand, the first divided bar code formed in the first authentication kit, as shown in Figure 5, the remaining bar code deleted in addition to the first area 310 and the second area 320 (third area 330 of the second divided bar code) And a first dummy area 340 having a size of a bar code), and may be configured in the same form as the overall size and shape of the bar code previously issued by the subject. This may have the effect of eliminating awkwardness due to the partial barcode formed in the first authentication kit by being configured in the same shape and size as the entire size of the barcode previously issued by the subject. In this case, the same size of the bar code means the same ratio, and not the general size.

As such, the shape of the first divided barcode may be various embodiments within the scope of the technical idea of the present invention.
