A method and device for generating a picture verification code, and an identity verification method and device

Abstract

Disclosed are an image verification code generating method, an identity verification method and an identity verification device. The image verification code generating method includes: cutting a preset image into at least two fragments, and recording a legal order for splicing the fragments into the preset image; selecting at least one of the fragments as a to-be-processed fragment, and subjecting the to-be-processed fragment to filtering treatment; storing the fragments as a whole, performing identity verification as required, randomly spicing an image verification code by the fragments, and sending the image verification code to a client end. By the scheme, a server is enabled to automatically identify legal users and illegal users, the illegal users are prevented from cracking the verification code via computer programs, identifying difficulty for the users is not increased, and user experience is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for generating a picture verification code, and an identity verification method and device. Background technique [0002] With the continuous development of computer and Internet technology, the Internet has penetrated into people's daily life, which not only brings convenience to people, but also brings various risks. Some malicious users will use computers to seize a large number of network resources, such as repeatedly registering and logging in to the website server, submitting garbage data to the server, etc., which wastes server resources, affects the normal use of legitimate users, and may even cause server paralysis in severe cases. In addition, some malicious users continue to visit the server, trying to crack the website super administrator account or ordinary legitimate user account, etc., which seriously damages the user's privacy an...

Problems solved by technology

But simple characters are easy to be read by computer programs, so in order to increase the difficulty of this verification method being cracked by computer programs, certain processing will be performed on the characters in the picture, such as processing the text into irregular crooked shape, add some interfering pixels, lines, fill the verification code background with different colors, etc., which increases the difficulty of computer-level recognition of verification codes, but also increases the difficulty of user recognition, and accordingly prolongs the verification code. It shortens the time for the user to input the verification code, affects the user experience, and causes the verification code to lose its usability to a certain extent
