Problems solved by technology

However, these methods have potential safety hazards. For example, only using the signature method, the merchant did not carefully check whether the signature matches the handwriting reserved on the credit card. When the credit card is lost, it is easy to imitate the handwriting for malicious consump

Embodiment 1

[0088] Figure 4 It is a flowchart of a credit card encryption method in Embodiment 1 of the present invention. Such as Figure 4 As shown, the following steps S401-S409 are included:

[0089] Step S401, sampling the voice password entered by the cardholder, extracting the sampling point and obtaining the feature value of the sampling point;

[0090] Step S402, generate a two-dimensional code according to the characteristic value of the sampling point and the information of the payment account, and reserve the two-dimensional code in the payment terminal;

[0091] Step S403, during the payment process, obtain the two-dimensional code information by scanning the two-dimensional code;

[0092] Step S404, analyzing the two-dimensional code information to obtain the characteristic value of the voice password and the information of the payment account;

[0093] Step S405, obtaining the input speech, and obtaining the feature value of the speech;

[0094] Step S406, matching th...

Abstract

The invention discloses a credit card encryption method and device, applied to generate a QR (quick response) code according to a voice password recorded by a card owner and information of a payment account so as to encrypt an information card. The method includes: generating the QR code; sampling the voice password recorded by the card owner, and extracting a sampling point, and acquiring a feature value of the sampling point; according to the feature value of the sampling point and the information of the payment account, reserving the QR code in a payment terminal. The existing traditional password-signature payment mode of the credit card is changed, and greater convenience, safety and reliability is achieved.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a credit card encryption method and device. Background technique [0002] With the development of society, the credit card business of banks continues to develop, and credit cards are more and more widely used in people's lives. According to the common practice of international banks, when consumers use their credit cards, they use their own signatures as evidence to confirm the consumption, and banks and merchants also use this signature as a basis for settlement. At present, in order to ensure the consumption safety of credit cards, most of them adopt the method of signing and adding passwords. However, these methods all have potential safety hazards. For example, only the signature method is used, and the merchant does not carefully check whether the signature matches the handwriting reserved on the credit card. When the credit card is lost, it is easy to imitate...
