Abstract

The invention discloses a human-machine recognition method of CAPTCHA, comprising: collecting a sample data set including one or multiple groups of training sample data and corresponding tags set forthe groups of training sample data, wherein the tags represent attributes of users; using the sample data set to train a machine learning model; collecting real-time user data; predicting the real-time user data according to the machine learning model so as to determine a user's attribute.

Description

technical field [0001] The disclosure mainly relates to the technical field of machine learning, and more specifically, relates to a human-machine identification method of a slider verification code. Background technique [0002] Human-computer identification is a public Turing machine test used to identify whether the log-in is a normal user or an abnormal user, and to distinguish between computers and humans. Abnormal users, that is, computers or machines, can request login by continuously visiting websites, and simulate normal users to input verification codes to attack website services. Therefore, it is very important to defend against attacks on large websites by identifying whether the login request is a normal user or an abnormal user. [0003] The verification code (CAPTCHA) is the abbreviation of "Completely Automated Public Turing test to tell Computers and Humans Apart" (Turing Test to Tell Computers and Humans Apart), which is a public fully automatic program to...
