Abstract

The invention provides a generation method and device of dynamic verification code pictures and a verification method and device of the dynamic verification code pictures in order to reduce the success rate of automatic identification through a machine. The generation method of the dynamic verification code pictures includes the steps that at least two frames of static verification code pictures are acquired, wherein in each frame of static verification code picture, a verification code is displayed after first display content and second display content are played; the static verification code pictures are played, and the dynamic verification code pictures are obtained, wherein in the playing process, first dynamic content is obtained according to the first display content, second dynamic content is obtained according to the second display content, and the first dynamic content and the second dynamic content contain different kinds of dynamic information. Through the method, the success rate of automatic identification through a machine can be lowered, the risk that verification codes are cracked is reduced, and the safety of a network is improved.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to a method and device for generating a dynamic verification code picture, and a verification method and device. Background technique [0002] In order to prevent certain users from using machines to automatically perform computer operations such as login, posting information, and downloading, many websites require users to enter verification codes when users perform related computer operations. The verification code is usually displayed in the form of a picture, and the user inputs the characters shown in the picture. [0003] At present, static verification code pictures are usually used. In order to reduce the success rate of recognition, the characters can be blurred, distorted, and noise can be added to the background. However, due to the increasingly powerful automatic recognition capabilities of machines, there are still high recognition rate. [0004] In order to ...
