The invention provides a dynamic two-dimensional code generating method, reading method, generating apparatuses and reading apparatuses. According to the technical schemes of the invention, the dynamic two-dimensional code generating method includes the following steps that: each frame of two-dimensional image generated by the dynamic two-dimensional generating apparatus carries a dynamic two-dimensional code corresponding to the display frequency information of the two-dimensional image; and the two-dimensional image is displayed according to the display frequency information of the two-dimensional image in the dynamic two-dimensional code. The dynamic two-dimensional code reading method includes the following steps that: the dynamic two-dimensional code reading apparatus reads one frame of two-dimensional image in a dynamic two-dimensional code with the reading frequency of the dynamic two-dimensional code reading apparatus itself, and performs image processing on the two-dimensional image, and decodes the two-dimensional image which has been subjected to the image processing so as to obtain display frequency information corresponding to the two-dimensional image; and all the rest unread two-dimensional code images in the dynamic two-dimensional code are read according to the display frequency information of the two-dimensional image.
Description
technical field [0001] The invention relates to two-dimensional code technology, in particular to a method and a device for generating and reading a dynamic two-dimensional code. Background technique [0002] Two-dimensional code / two-dimensional bar code (2-dimensional bar code) records data symbol information with a specific geometric figure distributed on a plane (two-dimensional direction) according to certain rules, and records data symbol information through image input equipment or photoelectric scanning The device automatically reads to realize the automatic processing of information. [0003] As login credentials, traffic entry, identity credentials, payment credentials, etc., QR codes are spread across various e-commerce platforms, shopping malls, websites, magazines, and even train tickets, and have become the new darling of the mobile Internet era. [0004] With the wide application of two-dimensional codes, its security has attracted more and more attention. For...
