Problems solved by technology

[0003] Due to the influence of factors such as vehicle movement, electromagnetic interference, dense crowds, and the geographical location of the platform, the network of bus vehicles has problems of poor stability and low reliability. The online payment mode of QR codes that relies entirely on the network is not feasible.

Embodiment Construction

[0037] The embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. The following are only preferred embodiments of the present invention, and are not intended to limit the present invention.

[0038] Such as figure 1 , offline payment based on QR code, firstly needs to initialize the system, the account issuer server uses the SM2 algorithm to generate an asymmetric key updated in the form of a daily cycle; the terminal server regularly updates the account issuer information list and user blacklist, the account issuer The issuer information list includes the account issuer information and the public key information of the asymmetric key; the account issuer server evaluates the user's credit and provides the user with a micropayment credit guarantee, and the user sends the account number to the account issuer server through the mobile client Apply to obtain a corresponding user certificate signed by the private key of...

Abstract

The invention discloses a two-dimensional code-based offline payment method. According to the method, asymmetric keys are adopted to issue certificates, so that the identity information of users is prevented from being forged and tampered; the asymmetric keys are managed by account issuers, so that the safety rights and interests of the account issuers are ensured; a terminal can realize the support for a plurality of account issuers and keep the simplicity and invariability of programs by adoption of a dynamic public key list updating manner; and a double-time stamp mechanism is adopted, one time stamp key is controlled by terminal operators and is used for preventing replication, and the other time stamp key is controlled by the account issuers and is used for preventing the terminal operator from forging transactions.

Description

technical field [0001] The invention relates to a two-dimensional code payment method, in particular to an off-line payment method based on a two-dimensional code. Background technique [0002] With the gradual popularization of smart phones, two-dimensional codes, as a mature image data encoding and recognition technology, have the advantages of low mobile phone hardware requirements, fast recognition speed, and can support a large number of users, and have been widely used. However, the traditional bus industry is still stuck in the way of swiping cards or inserting coins, so citizens have put forward demands for the application of QR code payment in the bus industry. [0003] Due to the influence of factors such as vehicle movement, electromagnetic interference, dense crowds, and the geographical location of the platform, the network of bus vehicles has problems of poor stability and low reliability. The online payment mode of QR codes that relies entirely on the network ...
