Abstract

The invention discloses a dynamic two-dimensional code and an identification method and identification device thereof, and relates to the technical field of computers. One specific embodiment of the method comprises the steps of obtaining information of a current picture frame, the information comprising generation time of the picture frame, a total frame number and a current frame serial number,and the picture frame being used for displaying a static two-dimensional code; judging whether the picture frame is valid according to the generation time; if the picture frames are valid, judging whether all the picture frames included in the dynamic two-dimensional code are identified or not according to the current frame number, the total frame number and the identified picture frame number; and if yes, extracting effective information of the dynamic two-dimensional code to complete identification of the dynamic two-dimensional code. According to the embodiment, the identification end can accurately judge the validity of the dynamic two-dimensional code, so that the security problem of the two-dimensional code caused by forwarding after screen capture or screen recording by others is prevented, and the security of the dynamic verification code and the identification process of the dynamic verification code is improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a dynamic two-dimensional code and its identification method and identification device. Background technique [0002] At present, most of the QR codes used on electronic devices are displayed as static pictures, which can be screenshotted and forwarded at will, and are still valid. In some special scenarios, such as payment or identity information verification, it should be limited to personal use, but some people will send QR code screenshots to others for use. Since the QR code is static, it is still valid after the screenshot , and it is not easy for the party who scans the code to intuitively judge whether the QR code is a screenshot, so it will bring a great security risk. What's more, in order to increase their own performance, some operators cheated with customers regardless of the interests of the boss behind them, causing losses to the actual stakeholders. So...
