Bar code copy prevention method and device therefor

Abstract

The present invention relates to a bar code copy prevention method and a device therefor. In detail, when a terminal provides a one-time bar code for an electronic payment, the one-time bar code is provided to a user in a state which a bar code scanner cannot recognize by changing the one-time bar code for the electronic payment, and when the bar code scanner exposes a light source in order to recognize the one-time bar code for the electronic payment, a light source recognition module installed in the terminal recognizes the light source of the bar code scanner, a payment may be performed by recovering an original bar code which the bar code scanner can recognize from the changed bar code, and thus an illegal use of the bar code may be prevented since the payment is not performed using the captured bar code.

Description

technical field [0001] The present invention relates to a barcode copy prevention method and a device used in the method, and more particularly, to a barcode copy prevention method and a device capable of preventing a barcode from being copied through barcode capture by the following operations: changing part or all of the barcode It is a state that the barcode scanner cannot recognize, and when a barcode for electronic payment is generated and the generated barcode is output to the terminal, a changed barcode is output. Background technique [0002] What is described in this section merely provides background information related to the embodiments of the present invention and may not constitute prior art. [0003] According to the development of terminal specifications and mobile communication networks, mobile communication terminals have been separated from the category of traditional simple communication equipment or information providing equipment and have become a must-...

Problems solved by technology

[0005] In particular, various electronic payment methods using barcodes in which barcodes are used by using barcode providing technology in mobile communication terminals have been tried, but in order to perform electronic payment using near field communication (NFC), there are the following problems: mobile communication terminals are required and should replace the attached store payment terminal, and therefore, barcodes that can be used for product identification that do not require hardware changes of mobile communication terminals and barcode scanners that have been used have been widely used for electronic payments

[0006] However, in electronic payment using a barcode, there is a disadvantage of reduced security compared with NFC, and in order to solve this disadvantage, a one-time barcode having a short effective time has been developed and applied, but even when using a one-time barcode In the electronic payment, another user can also use the captured barcode to perform payment after capturing the barcode through the capture function of the mobile communication terminal. Because it is difficult to distinguish the captured barcode from the original barcode with the naked eye, the mobile communication terminal is blocked by malicious codes, etc. Infections and theft of personal information are on the rise, and the risk of illegal payments is increasing
