[0045] see image 3 , which is a flow chart of the second embodiment of a method for generating a question-type picture verification code provided by the present invention, including:

[0046] After step S7, also include:

[0047] Step B, obtaining the verification code picture submitted by the user according to the question-type picture verification code, and detecting whether the verification code picture matches the verification answer;

[0048] When the verification code picture matches the verification answer, the verification is qualified;

[0049] When the verification code picture does not match the verification answer, the verification fails.

[0050] In this embodiment, the server records the splicing position according to the standard answer of the question-type question picture (that is, the verification code picture). verification answer, to verify the verification answer submitted by the user; when the verification code picture matches the verification answer,...

Abstract

The invention provides a question type picture verification mode generation method. The question type picture verification mode generation method comprises the steps of collecting all kinds of pictures and labeling the pictures according to the type to generate corresponding labels; building different question type questions based on the picture types and label content; associating the question type questions with pictures by combining the picture labels with different types of question type questions; selecting one question type question randomly from all the question type questions as a question of a question type picture verification code by utilizing a random function; selecting corresponding correct pictures and wrong pictures randomly based on the selected question type question; splicing the correct pictures and the wrong pictures randomly to generate a verification code image; and generating the question type picture verification code by utilizing the question type question andthe spliced verification code image. The question type picture verification mode generation method can increase the difficulty which is easily cracked in a verification process efficiently and can guarantee verification safety; and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of network applications, in particular to a method 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...
