Credit card encryption method and device

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.

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 consumption.

There are certain security risks when the signature and password are transmitted between the POS machine and the bank through the communication line by using the signature encryption method. Once criminals use high-tech means to intercept this information, it will bring great losses to consumers.
