Problems solved by technology

[0003] The present invention overcomes the deficiencies in the prior art and provides a method and system for realizing network verification in a question-and-answer manner. It uses the system to randomly generate several verification code prompt questions, and uses the method of selecting the corresponding answer to the verification code prompt question to judge whether the user has obtained Whether the verification code is valid or not, these ever-changing verification code prompt questions can be designed to make it easy for people to find the correct answer, but for robots, it is very difficult to identify the question and choose the answer; in the design, you can require It is very easy for people to choose the answers (or more) corresponding to 4 to 5 questions, but it is very difficult for robots to find out all the answers completely correctly, so as to maintain network security by using verification code technology , for the purpose of preventing cheating

Embodiment 1

[0008] Example 1, such as figure 1 Shown: a method and system for implementing network verification in a question-and-answer manner, including a question generator 1 , an answer selection device 2 and a verification code judging mechanism 3 . It is characterized in that: the question generator 1 generates at least one verification code prompt question, the answer corresponding to the question is selected through the answer selection device 2, and the verification code judging mechanism 3 judges whether the corresponding answers selected by the user are all correct, and if they are all correct, then It is determined that the user has passed the verification of the verification code, otherwise it is determined that the user has not passed the verification of the verification code.

[0009] In the above embodiment, it is assumed that the question generator 1 randomly generates 4 questions, which are questions a1, a2, a3, and a4 respectively. The user must select the answer corres...

Abstract

The invention discloses a method for realizing network authentication in a question-and-answer manner and a system for realizing the network authentication in the question-and-answer manner. The system includes a question generator, an answer selection device and a verification code judging mechanism. The system is characterized in that the question generator generates at least one verification code prompt question; answers corresponding to the question are selected through the answer selection device; and the verification code judging mechanism judges whether answers selected by a user are correct or not, if the answers are all correct, the verification code judging mechanism affirms that the user passes the verification of verification codes, otherwise, the verification code judging mechanism affirms that the user does not pass the verification of the verification codes. In the design, people can easily find answers for ever-changing questions, while, a robot is difficult to select correct answers.

Description

technical field [0001] The invention belongs to the technical field of verification code protection for preventing network brute force cracking, and in particular relates to a method and system for realizing network verification in a question-and-answer manner. Background technique [0002] Verification codes play an increasingly important role in preventing brute force cracking, malicious registration and login attempts, and preventing online ticket swiping. It is precisely because of this special effect of verification codes that some unscrupulous merchants or hackers have developed some programs. , the so-called robot program, which can automatically recognize verification codes that are easily recognizable to the naked eye. Therefore, in order to make better use of the special functions of verification codes, the current verification code technology tends to increase the difficulty of human naked eye recognition, so it is more difficult for robots to identify, so as to ...
