Abstract

The invention is suitable for the technical field of access control, and provides an access control authentication method based on a dynamic two-dimensional code. The access control authentication method comprises the following steps of scanning an image of the two-dimensional code, and decrypting, so as to obtain the information of the two-dimensional code; judging whether the current time is setwithin the effective time or not, and judging whether the frequency of scanning the image of the same two-dimensional code is smaller than or equal than the effective frequency or not; when the current time is set within the effective time, and the frequency of scanning the image of the same two-dimensional code is smaller than or equal than the effective frequency, sending ID (identification) ofa user to an access control controller. The access control authentication method has the advantages that by analyzing and decrypting the two-dimensional code, the failure to analyze the two-dimensional code or decrypt the data indicates that the scanned two-dimensional code is not the correct two-dimensional code for opening a door, thereby effectively preventing the malicious opening of the access control; the effective time and effective frequency are judged after decrypting, thereby furthermore preventing the malicious opening of the access control, improving the anti-theft ability, and reaching higher security.

Description

technical field [0001] The invention belongs to the technical field of access control, in particular to an access control authentication method based on a dynamic two-dimensional code. Background technique [0002] With the advancement of science and technology, intelligent access control technology has been widely used in the management and control of public places such as office buildings and intelligent communities. At present, most of the existing access control systems use the access control card technology, because the access control card is inconvenient to carry. Here, you only need to scan the two-dimensional code when using it. Although this technology is more convenient to use and the cost is relatively low, but because the existing two-dimensional code access control uses fixed two-dimensional code pictures, it is easy to be used. Others copy or take pictures, poor security. Moreover, in order to convert the original access control equipment that recognizes the ...
