Embodiment Construction

[0055] The following is a detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and preferred embodiments. This patent is based on the original static two-dimensional code, providing a safer and more reliable two-dimensional code generation and verification technology - dynamic two-dimensional code.

[0056] The dynamic QR code image is generated by a component that can be deployed across platforms. This component can be deployed on a variety of hardware carriers, such as ATMs, personal computers, web browsers, etc. This component mainly realizes the following functions:

[0057] 1. Data encryption:

[0058] In order to prevent the content of the QR code from being parsed by a common QR code scanner, it is necessary to encrypt the content of the QR code. The encryption method is encrypted with a security algorithm that conforms to the national secret standard.

[0059] 1) The dynamic two-dimensional code g...

Abstract

The invention refers to the technical field of coding and decoding of a two-dimensional code, and particularly relates to a method for generating and verifying a dynamic two-dimensional code. The method for generating and verifying the dynamic two-dimensional code includes the following steps: generating the dynamic two-dimensional code according to original data input by a user and encrypting the data content of the dynamic two-dimensional code; applying a mobile terminal to scan the dynamic two-dimensional code and performing time verification, data decryption, inspection of data integrity and hardware information matching on one frame of obtained dynamic two-dimensional code data; if the whole inspections are passed, performing subsequent normal flows; otherwise, giving up the data. The dynamic two-dimensional code makes that every two-dimensional code image is dynamically encrypted and generated by using different secrete keys respectively within a period of time on the basis of an original QR Code; its content is encrypted through a security algorithm according with the national password standard and then mixed, so that the data transmission is safer.

Description

technical field [0001] The invention relates to the technical field of coding and decoding of two-dimensional codes, in particular to a method and system for generating and verifying dynamic two-dimensional codes. Background technique [0002] With the development of technology and network technology, especially the popularity of smart phones in recent years, and the rapid development of mobile Internet technology, network information transmission has penetrated into all aspects of people's lives, such as electronic shopping, social networking, online marketing, instant messaging, etc. etc.; with the emergence of these services, two-dimensional codes have gradually been widely used in the Internet field due to their large storage capacity, easy identification and analysis, and rapid spread on the Internet. [0003] In recent years, with the popularity of smart phones, the Internet of Things, and the mobile Internet have developed extremely rapidly. Many companies and institu...
