Prompt method for verification code based on image carousel

Abstract

The invention discloses a verification code prompting method based on picture carousel, which comprises the following steps: step S100, a terminal receives M+1 picture and a playback order of the picture, wherein the M+1 picture comprises a reference picture and M verification guide pictures; each picture comprises a lattice of P*Q; in the reference picture, each point in the dot matrix has the same display characteristics; in the verification guide picture, the lattice comprises one verification guide point and P*Q-1 non-verified pilot points; in the verification guide picture, the verification guide point and the point in the reference picture have different display characteristics, and the non-verification guide point and the point in the reference picture have the same display characteristics; Step S200, the terminal plays the received M+1 picture in turn according to the playing order; during playing according to the playback order, the verification guide points in the M verification guide pictures forming a verification code trajectory.

Description

technical field [0001] The present invention relates to the field of identity verification, in particular to a method for prompting verification codes based on picture carousels. Background technique [0002] At present, Internet platforms may be attacked at any time, such as spam registration, SMS spam, scalpers grabbing tickets, fake voting, etc. Most of these attacks are executed through automated scripts. The full name of the verification code (CAPTCHA) is "Completely Automated Public Turing test to tell Computers and Humans Apart", which can avoid the attack of automated script execution to a large extent. The verification codes that have been commercially applied in the prior art mainly include such as figure 1 The verification code for recognizing letters as shown, such as figure 2 The verification code of the sliding puzzle method shown, such as image 3 The verification code and other ways to identify the text in the picture as shown. Tencent has disclosed the ...

However, this form of video or animation also has technical deficiencies, which are reflected in the one-to-one correspondence between the video or animation and the verification code, that is, a video or animation can only display one verification code, and the video or animation takes up storage space. Large, resulting in a small number of videos or animations, so it is easy to obtain the corresponding relationship between videos or animations and verification codes through manual exhaustive methods, so as to complete the cracking
