[0034] figure 1 It is a flowchart of a secure payment method based on a trusted two-dimensional code provided in the first embodiment of the present invention. The method in this embodiment can be executed by a secure payment system based on a trusted two-dimensional code. The system includes a two-dimensional Code issuer, QR code management platform and QR code display party. The method of this embodiment specifically includes the following steps:

[0035] Step 110, the two-dimensional code issuer performs digital signature calculation on the original information, generates first signature information, and sends the first signature information and original information as first information to the two-dimensional code management platform. Wherein, the original information includes item information and payment information.

[0036] In this embodiment, the two-dimensional code issuer does not directly generate the two-dimensional code, but sends the original information for gen...

[0062] figure 2 It is a flow chart of a secure payment method based on a trusted two-dimensional code provided in the second embodiment of the present invention. On the basis of the above-mentioned embodiments, this embodiment uses a public key pair to perform digital signatures. Wherein, the two-dimensional code issuer stores the first public key-private key pair, including the first public key and the first private key, and stores the first public key in the two-dimensional code management platform at the same time; the two-dimensional code management platform stores the first public key The second public key-private key pair includes a second public key and a second private key, and simultaneously stores the second public key on the two-dimensional code display party. The method of this embodiment specifically includes the following steps:

[0063] Step 210, the two-dimensional code issuer generates an information summary for the original information according to a predet...

[0083] image 3 and Figure 4 It is a flow chart of creating and scanning an authentic two-dimensional code according to the third embodiment of the present invention. In this embodiment, the two-dimensional code issuer is the payee in the payment activity. The two-dimensional code management platform is established through CMS and opened to the payee through web page login. The two-dimensional code issuer first needs to enter the Register on the CMS webpage. After the registration is successful, the QR code management platform will assign a USB shield to the QR code issuer to verify the identity of the payee; the QR code display party is the payer in the payment activity, and the QR code The code management platform provides a specific scanning client for the payer to realize the credible verification of the received QR code by the payer.

Abstract

The invention discloses a safety payment method and system based on a credible two-dimension code. The safety payment method comprises the steps that a two-dimension code publisher performs digital signature computation on original information to generate first signature information and sends the first signature information and the original information, as first information, to a two-dimension code management platform; the two-dimension code management platform verifies the first information, performs digital signature computation on payment information to generate second signature information when the first information passes the verification, encodes the second signature information and the original information to generate the credible two-dimension code, and sends the credible two-dimension code to the two-dimension code publisher; the two-dimension code publisher sends the credible two-dimension code to a two-dimension code displayer; the two-dimension code displayer verifies the credible two-dimension code, and displays the original information in the credible two-dimension code when the credible two-dimension code passes the verification. According to the method and the device, the risk of a user in the two-dimension code using process is reduced, the safety of the two-dimension code is ensured, and the reliability of the two-dimension code payment system is further improved.

Description

technical field [0001] The embodiments of the present invention relate to the fields of computer technology and information security, and in particular to a secure payment method and device based on a trusted two-dimensional code. Background technique [0002] With the advent of the 3G (3rd-Generation, third-generation mobile communication) era, the mobile Internet has become the industry with the fastest growing speed, the largest market potential and the most attractive prospect in the world today. Now a large part of people's consumer goods are traded through the Internet, and more and more people choose mobile Internet for payment. [0003] In an existing mobile-oriented payment technology, the payment platform (for example: Alipay) uses mobile Internet communication to transplant the payment function of the PC (Personal Computer, personal computer) terminal to the mobile terminal; combined with the mobile phone to scan the QR code, Complete on-site payment. Among them...
