Abstract

The invention discloses a method and a device for starting two-dimensional code display. The method comprises the following steps: display equipment sends target parameters to a background server; thebackground server receives the target parameters sent by the display equipment, generates a ciphertext based on the target parameters and a predetermined encryption parameter, and sends ciphertext parameters to the display equipment; and the display equipment receives the ciphertext parameters sent by the background server, decrypts the ciphertext parameters to obtain a target two-dimensional code URL corresponding to the ciphertext parameters, converts the target two-dimensional code URL into a target two-dimensional code image, and displays the target two-dimensional code image. Before thetwo-dimensional code display is started, information corresponding to the display device for displaying the two-dimensional code is encrypted to obtain the encrypted ciphertext, and the encrypted ciphertext is parsed to obtain the two-dimensional code URL, so that the two-dimensional code image corresponding to the two-dimensional code URL is displayed, the safety and reliability of the two-dimensional code data are improved, and the possibility that the two-dimensional code information is copied and propagated is reduced.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a method and device for starting two-dimensional code display.
