Verification response method and system based on picture verification code

Abstract

The present invention relates to a verification response method based on picture identification codes. The method comprises the following steps: a response server receives a picture identification code pulling request, wherein the picture identification code pulling request includes the picture file format of the picture identification code requiring pulling; the response serve pulls a lattice picture including identification code character generated in advance; the response serve converts the lattice picture to the picture identification code having the picture file format; and the response serve returns back the picture identification code to the sender of the picture identification code pulling request. The verification response method based on picture identification codes can ensure the response speed, ensure that the generation amount of the picture identification code of each picture file format is equal to the protection of the pulling amount without wasting the computer resource of generating the picture identification codes, and ensure the supply of each picture identification code. The present invention further provides a verification response system based on the picture identification code.

Description

technical field [0001] The invention relates to the field of identity verification, in particular to a verification response method and system based on a picture verification code. Background technique [0002] User accounts and passwords usually correspond to specific user rights and are related to user privacy information. Some hackers may make continuous login attempts to a specific registered user with a specific program, so as to achieve brute force cracking of the user's password. On the other hand, some hackers may also use specific computer programs to perform illegal operations such as flooding forums and swiping votes. Therefore, a program is needed to identify whether the user is a human or a computer. CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) is such a public automatic program that can identify whether the user is a human or a computer. [0003] CAPTCHA distinguishes whether the user is a computer or a human by adopti...

Problems solved by technology

Since the generation of the picture verification code takes a long time, in order to improve the response speed, the server usually pre-generates a certain number of picture verification codes in various picture file formats and stores them, and the picture verification codes of each picture file format The demand (pull volume) usually changes, resulting in a situation where the storage capacity of the image verification codes in some image file formats is insufficient, while the supply of image verification codes in some image file formats is insufficient
