Generation system for questioning-type picture verification code

Abstract

The invention provides a generation system for a questioning-type picture verification code. The system comprises a database, a collection module, a problem establishment module, an association module, a problem randomization module, a picture randomization module, an image splicing module and a verification code generation module. The database is used for storing pictures and questioning-type problems; the collection module is used for collecting the pictures in the database and generating corresponding labels according to type annotations of the pictures; the problem establishment module isused for establishing different questioning-type problems according to the types of the pictures and label content; the association module is used for associating the questioning-type problems with the pictures according to the picture labels; the problem randomization module is used for randomly selecting any one questioning-type problem as a problem of the questioning-type picture verification code from all the questioning-type problems; the picture randomization module is used for randomly selecting corresponding right pictures and wrong pictures according to the questioning-type problems;the image splicing module is used for randomly splicing the right pictures and the wrong pictures to generate verification code images; the verification code generation module is used for generating the questioning-type picture verification code by using the questioning-type problems and the spliced verification code images. According to the generation system for the questioning-type picture verification code, the breaking difficulty in the verification process is improved, the verification safety is guaranteed, and the user experience degree is also increased.

Description

technical field [0001] The invention relates to the technical field of network applications, in particular to a system for generating question-type picture verification codes. Background technique [0002] With the increasing popularity of computers and computer networks, the Internet has penetrated into all areas of people's work, study and life. Network development brings various challenges while providing convenience. In order to prevent attacks such as spam, batch registration and distribution of stolen resources, and false voting on the online voting system, the authenticity and security of the network cannot be guaranteed. In order to ensure the security of the Internet, many websites have adopted verification code technology. [0003] The full name of the verification code is the fully automatic Turing test that distinguishes between computers and humans. It originated from AltaVista in 1997. Its purpose is to prevent the automatic submission of URLs. A string of n...
