Authentication method for bank certificate printed with two-dimension code

Abstract

The invention discloses an authentication method for a bank certificate printed with a two-dimension code. The surface of the bank certificate is printed with a bank certificate two-dimension code. The authentication method comprises the following steps of: 101. analyzing an element item contained in the bank certificate two-dimension code information; 102. selecting a detection area; 103. printing the two-dimension code and the detection area: printing the two-dimension code and the detection area in the vacancy of the bank certificate; 104: authenticating the bank certificate: comparing whether the corresponding element item information on the detection area and the bank certificate is consistent; if yes, proving that the two-dimension code information on the bank certificate is correct; and if no, proving that the two-dimension code information on the bank certificate does not conform to information in the bank certificate. With the authentication method, the element item in the two-dimension code information serves as the detection area to be printed on the certificate in a plaintext mode, and whether the element item in the two-dimension code and the element item of the certificate are consistent can be quickly judged so as to make up the deficiency that the bank certificate can not be directly authenticated.

Description

technical field [0001] The invention relates to a method for verifying a bank certificate, in particular to a method for verifying a bank certificate printed with a two-dimensional code. Background technique [0002] Two-dimensional bar code (2-dimensional bar code) is a black and white graphic that is distributed on a plane (two-dimensional direction) according to certain rules to record data symbol information with a specific geometric figure. In the coding, the concepts of "0" and "1" bit streams that constitute the internal logic basis of the computer are skillfully used, and several geometric shapes corresponding to the binary are used to represent the text and numerical information, through image input devices or photoelectric scanning devices Automatic reading to realize automatic processing of information. Two-dimensional codes can express information in both horizontal and vertical orientations at the same time, so they can express a large amount of information in ...

Problems solved by technology

[0004] However, the two-dimensional code itself is printed in the form of graphics, and the information contained in it cannot be directly recognized. That is to say, the printing operator cannot judge whether the printing is correct from the graphics itself. I don’t know what the QR code information is. The pre-set element information is not easy to make mistakes, but it is unavoidable that errors in the element information set during printing will occur during manual input and printing. When using it, it will bring a lot of trouble or even cause losses to customers; when accepting vouchers, asking the acceptor to compare the information on the QR code with the information on the voucher will greatly reduce the acceptance speed, and when printing the printed voucher Passing the reading equipment inspection one by one will increase the huge workload
