Realization method for completely automated public turing test to tell computers and humans apart, and terminal

Abstract

The embodiment of the invention relates to the technical field of the internet and discloses a realization method for a completely automated public turing test to tell computers and humans apart, and a terminal. According to the method and the terminal, the realization method for the completely automated public turing test to tell computers and humans apart comprises the steps of displaying first screen location information and first pressure information, wherein the first screen location information is used for indicating a to-be-pressed screen location of a pressure sensing screen of a user side, and the first pressure information is the pressed pressure information of the to-be-pressed screen location; obtaining second screen location information and second pressure information, wherein the second screen location information indicates the pressed screen location of the pressure sensing screen, and the second pressure information is the pressed pressure information of the pressed screen location; comparing the first screen location information with the second screen location information, comparing the first pressure information with the second pressure information and carrying out verification according to comparison results. The invention also discloses the terminal. According to the embodiment of the method and the terminal, an identification success rate and identification difficulty can be balanced, and a computer program can be prevented from carry out the verification instead of a person.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a verification code realization method and a terminal. Background technique [0002] CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart, referred to as the fully automated Turing test to tell Computers and Humans Apart) is a public automatic program that distinguishes whether a user is a computer or a human, and can prevent violent cracking of user passwords , Swiping votes, flooding forums and other malicious behaviors. [0003] A commonly used verification code scheme is to allow users to input characters displayed on a distorted picture to avoid automatic recognition by computer programs. If the user can type correctly, the user is determined to be a human, not a computer program. [0004] The biggest disadvantage of this scheme is that it cannot balance the recognition success rate and recognition difficulty. If the graphics are too co...

[0004] The biggest disadvantage of this scheme is that it cannot balance the recognition success rate and recognition difficulty

If the graphics are too complex, it will be difficult for people to recognize and affect the user experience. If it is too simple, it will be easily recognized by computer programs, thus failing to achieve the purpose of the verification code
