Picture identifying code generation method and system, and verify method and client side, and server

Abstract

A picture identifying code generation method comprises the following steps: obtaining a background picture; obtaining foreground characters; embedding the foreground characters in the background picture so as to obtain a picture identifying code; generating interference element used for cutting the foreground characters and integrating with background picture color. The method uses the interference element integrating with the background picture color in the picture identifying code to cut the foreground characters, so an automatic machine can only extract foreground character fragments in the picture identifying code without extracting the whole foreground characters, thus increasing automatic machine difficulty of declassifying picture identifying code; the foreground characters are cut, yet a whole layout formed by the foreground character fragments allow the image identifying code to be easily recognized by a user, so the difficulty of the user identifying the picture identifying code is not increased; in addition, the invention also provides a picture identifying code generation system, a verify method based on the picture identifying code, a client side, and a server.

Description

technical field [0001] The invention relates to image processing technology, in particular to a method and system for generating a picture verification code. Background technique [0002] Captcha technology is a fully automated Turing test (Completely Automated Public Turing test to tell Computers and Humans Apart, CAPTCHA) that distinguishes between computers and humans. It is a public fully automated program that distinguishes whether a user is a computer or a human. Verification code technology is to generate a picture from a string of randomly generated numbers or symbols, and add some interference elements to the picture. The website is verified by the website, and the user can use a certain function only after the verification is successful. [0003] In order to prevent batch registration of computers, malicious cracking, flooding of forums, etc., general websites use verification code technology. The automaton is a computer program specially used to crack the pictur...

AI Technical Summary

Problems solved by technology

With the development of OCR (Optical Character Recognition, optical character recognition) technology, image verification codes are increasingly unable to resist the cracking of automatic machines

In order to increase the difficulty of automatic machine cracking, more and more complex interference elements need to be added to the picture verification code, but these interference elements will also greatly reduce the recognition rate of normal users for the picture verification code
