Embodiment 1

[0056] Attached below figure 2 Further introduce the working method of generating a dynamic two-dimensional code provided by the present invention, the specific operations are as follows:

[0057] Step 210: safety device initialization;

[0058] Security device initialization includes initializing the serial number, dynamic factor and master key, specifically: writing a serial number with a globally unique identifier for the security device, generating a master key through a key dispersal algorithm based on the serial number, initializing the dynamic factor and Server dynamic factor synchronization;

[0059] Wherein, the dynamic factor may be at least one of time factor, event factor, random input value, fingerprint information set or face information set.

[0060] When the dynamic factor includes a time factor, the initialization specifically includes: synchronizing the clock time of the security device with the clock time of the server; wherein the time factor changes wit...

Embodiment 2

[0097] The above combined figure 2 And attached image 3 Introduced the working method of the security device that generates dynamic two-dimensional code in embodiment one, below in conjunction with appendix Figure 4 A system for generating dynamic two-dimensional codes is introduced, including; a security device 410, a mobile device 420 and a server 430;

[0098] Security equipment 410 includes:

[0099] The initialization module 4101 is used to initialize the serial number, the master key and the dynamic factor;

[0100] The two-dimensional code generation module 4102 is used to regenerate the two-dimensional code picture according to the serial number, the master key and the dynamic factor every preset time;

[0101] The display module is used to display the two-dimensional code picture.

[0102] The mobile device 420 includes a processing module 4201 for scanning the picture of the two-dimensional code and sending the corresponding two-dimensional code data to the se...

Abstract

The invention relates to the field of information security, in particular to a security device, method and system for generating a dynamic two-dimensional code. The method includes: initializing the serial number, master key and dynamic factor; regenerating and displaying the two-dimensional code picture according to the serial number, master key and dynamic factor every preset time; the dynamic factor includes time factor, event factor, At least one of random data combination, fingerprint information set or face information set. By adopting the technical solution of the present application, a dynamic factor is added in the process of generating the two-dimensional code to achieve the purpose of regularly updating the two-dimensional code and preventing the two-dimensional code from being maliciously tampered with.

Description

technical field [0001] The present invention relates to the field of information security, because it relates to a security device, method and system for generating a dynamic two-dimensional code. Background technique [0002] With the widespread application of QR codes, QR code scanning payment has been applied to many application scenarios. Now in the QR code payment market, Alipay and WeChat occupy most of the market. When merchants use Alipay and WeChat to collect money, they can print out their own payment QR codes and paste them in places that are easier for customers to scan. When users pay the merchants, they can directly scan the merchants’ payment QR codes to make payment . [0003] However, since the printed two-dimensional code is static, it is easy to be tampered by criminals, causing unnecessary economic losses. Based on this, the application of the present invention is born. Contents of the invention [0004] In order to solve the problems in the prior a...
