Abstract

The invention discloses a graphic reasoning verification code recognition method, system and device and a medium. The recognition method comprises the steps of extracting a verification indication statement; detecting all alternative verification code graphs from the verification code image and obtaining attribute information corresponding to each alternative verification code graph; extracting akeyword from the verification indication statement; if the keywords include the reference object keywords, comparing the reference object keywords with the attribute characteristics of all the alternative verification graphs, selecting one of all the alternative verification graphs as a reference object, and determining the attribute characteristics of the target verification code graph by takingthe reference object as a reference; and screening out the alternative verification code graph conforming to the attribute feature as a target verification code image. The defects of low verificationcode recognition efficiency and poor recognition accuracy caused by a manual mode are overcome, the accuracy of graphic reasoning verification code recognition is effectively improved, and the response time for verifying the graphic reasoning verification code is shortened.

Description

technical field [0001] The invention relates to the field of image verification code recognition, in particular to a method, system, device and medium for graphical reasoning verification code recognition. Background technique [0002] Verification code (CAPTCHA) is widely used in Internet companies. It is a public automatic program that distinguishes whether a user is a computer or a human. It can prevent malicious cracking of passwords, swiping tickets, flooding forums, etc., thereby ensuring the stability of the server system and user information. security. [0003] Currently, the more common types of verification codes include picture verification codes, sliding window verification codes, and selection verification codes. If the verification code can be automatically identified, it can effectively assist the user to quickly pass the verification link of the verification code, thereby realizing automatic access to web pages and obtaining public information. [0004] How...
