Recognition system and recognition method for verification code of mobile platform

Abstract

The invention discloses a recognition system and a recognition method for a verification code of a mobile platform. The recognition system comprises a mobile platform verification code intercepting module, a verification code de-noising module, a verification code binaryzation module, a verification code recognition core module and a self-learning module, wherein the mobile platform verification code intercepting module is used for intercepting an original verification code image from the mobile platform to a verification code recognition system; the verification code de-noising module is used for de-noising the original verification code image through a median filtering algorithm so as to acquire a secondary verification code image; the verification code binary module is used for converting the secondary verification code image into a black and white bicolor image and cutting into a plurality of verification code sub-blocks; the verification code recognition core module is used for recognizing the well-cut verification code sub-blocks, acquiring a character string represented by the verification code and calculating an equation value represented by the character string; and the self-learning module is used for speculatively trying the possible optimizing character string and automatically recording a speculative value into a self-learning database if the speculative value correctly passes. The recognition system provided by the invention can be used for quickly and automatically recognizing the verification code contained in an interface supplied by the mobile platform and promoting the user experience.

Description

technical field [0001] The invention relates to the field of verification code identification, in particular to a mobile platform verification code identification system and identification method. Background technique [0002] The Completely Automated Public Turing test to tell Computers and Humans Apart (CAPTCHA for short), commonly known as CAPTCHA, is a public fully automatic program that distinguishes whether a user is a computer or a human. In a CAPTCHA test, a computer acting as a server automatically generates a question for the user to answer. This question can be generated and judged by a computer, but only a human can answer it. Since computers cannot answer CAPTCHA questions, users who answer the questions can be considered human beings. [0003] CAPTCHA is currently widely used on message boards of websites. In order to prevent people from using computer programs to post a large number of advertisements or other spam on the message boards, many message boards w...
