Method and equipment for providing picture verification code based on verification security level

Abstract

The invention aims to provide a method and equipment for providing a picture verification code based on a verification security level. The method comprises the following steps: enabling the verification code providing equipment to acquire a verification request submitted by a user in a visited page through user equipment; according to user related information of the user, determining a verification security level corresponding to the verification request; according to the verification security level, acquiring a picture verification code corresponding to the verification request; and providing the picture verification code to the visited page. Compared with the prior art, the invention can provide picture verification codes of different levels based on verification security levels, thereby increasing the machine recognition difficulty, and simultaneously facilitating user verification and improving the use experience of the user.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a technology for providing a picture verification code based on a verification security level. Background technique [0002] CAPTCHA is the abbreviation of "Completely Automated Public Turing test to tell Computers and Humans Apart" (Turing Test to Tell Computers and Humans Apart), which is a public fully automatic program to distinguish whether the user is a computer or a human. The main purpose of verification codes is to force human-computer interaction to defend against machine automation attacks. Using verification codes can also effectively prevent malicious password cracking, swiping tickets, and flooding forums. In the prior art, the difficulty levels of the picture verification codes used in the same application are basically the same, which leads to that if the difficulty level is too high, although the security is improved, it is not conducive to user identificati...

Problems solved by technology

In the prior art, the difficulty levels of the picture verification codes used in the same application are basically the same, which leads to the fact that if the difficulty is too high, although the security is improved, it is not conducive to user identification; if the difficulty is too low, then bad for network security
