Abstract

The invention discloses an off-line authorization method and system under a non-communication condition. The method comprises the following steps: an instruction sending end displays an information image; the instruction receiving end obtains the information image and analyzes the information image to obtain analysis data; and verifying and determining whether the information image is correct by analyzing the data, and if so, executing an instruction corresponding to the information image. According to the application, the instruction sending end and the instruction receiving end control the instruction receiving end through the information image under the non-communication condition, so that the accuracy of information transmission and the efficiency of information transmission can be ensured.
