Operating authorization method and system based on dynamic two-dimensional code

The invention provides an operating authorization method based on a dynamic two-dimensional code. The method includes the steps that a dynamic secret key is generated according to real-time data relevant to a device to be controlled; a link and the dynamic two-dimensional code corresponding to the link are generated according to the dynamic secret key; the link is acquired through analysis of the dynamic two-dimensional code by scanning, and access to the link is finished; the dynamic secret key is acquired according to the link; the dynamic secret key is verified, and if the dynamic secret key passes verification, a control interface for controlling the device to be controlled is provided. Accordingly, the invention further provides an operating authorization system based on the dynamic two-dimensional code. Uniqueness of authorization is achieved through the dynamic two-dimensional code when a user acquires control authority of the device to be controlled, and safety of authorization is effectively improved; in addition, the user can acquire the control authority of the device to be controlled by scanning and analyzing the dynamic two-dimensional code, operation is convenient and quick, and user experience is good.
