Description

Authentication method using divided bar-code}

The present invention relates to an authentication method using a barcode, and in particular, to issue a first divided barcode by dividing a barcode in which first authentication information corresponding to a subject requesting authentication is authenticated in a transaction requiring authentication, and issuing the first divided barcode. An authentication method using a split bar code that performs a requested authentication by determining whether a bar code including 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 method using a split barcode that can improve the castle.
