Embodiment Construction

[0023] figure 1 It is a flow chart of the method for generating an electronic check two-dimensional code voucher in the present invention. like figure 1 As shown, the method for generating an electronic check two-dimensional code voucher includes:

[0024] The payment platform receives the request from the user to generate an electronic check QR code voucher, the request includes the original certificate information, and the original certificate information specifically includes the necessary information of the voucher such as the password used for the voucher, the amount issued, and the purpose of the voucher;

[0025] The encryption module encrypts the original plaintext information of the voucher according to the encryption algorithm to generate the ciphertext information of the original voucher: After the payment platform receives the request from the user, the encryption module generates the encrypted original voucher ciphertext information according to the encryption al...

Abstract

The invention relates to an electronic check two-dimensional code certificate generation method, which comprises the following steps: a request with source document cleartext information for generating an electronic check two-dimensional code certificate is received, and source document ciphertext information is generated; two-dimensional code pictures are generated; source number summary information is computed and source document identifying codes are generated; source document identifying codes are embedded into the two-dimensional code pictures in the form of digital watermark, thus acquiring the two-dimensional code certificate. The verification method for the electronic check two-dimensional code certificate comprises the following steps: a two-dimensional code certificate and a code are received; the two-dimensional code certificate is decoded to generate new certificate ciphertext information; new number summary information is figured out after decryption; the source number summary information is reverted; two pieces of number summary information are compared; and the verification results are fed back. In the electronic check two-dimensional code certificate generation method, the electronic check two-dimensional code certificate with digital watermarks is generated by certificate information ciphering and by adopting embedded identifying codes in the form of digital watermarks. In this way, the two-dimensional code certificate can not be reproduced or fabricated, thus significantly improving the forgery prevention and the security of electronic checks.

Description

technical field [0001] The invention relates to a method for generating and verifying a two-dimensional code certificate, in particular to a method for generating and verifying an electronic check two-dimensional code certificate. Background technique [0002] As a financial payment certificate, checks have strict restrictions and requirements in terms of technical security and business processes. With the rapid development of financial electronic systems based on computer and network communication technology, banks and other financial institutions urgently need to improve the processing speed of their bill business. Electronic check is a form of electronic payment that draws on the advantages of traditional paper check transfer payments and uses digital transfers to transfer money from one account to another. Compared with traditional paper checks, electronic checks are more convenient, fast, and low-cost, and present a trend of replacing traditional paper checks. [0003...
