Embodiment approach

[0099] According to an embodiment of the present invention, the feature extraction module includes: a statistical analysis sub-module for analyzing the spatial features and motion direction features of the operation data to obtain the statistical feature vector of the operation data; a dimensionality reduction sub-module for using principal components Analyze the PCA dimensionality reduction method to extract the nonlinear eigenvectors of the operating data; the splicing sub-module is used for vector splicing of statistical feature vectors and nonlinear eigenvectors.

[0100] It should be pointed out here that: the above description of the embodiment of the human-machine identification device is different from the aforementioned Figures 1 to 4 The description of the illustrated method embodiment is similar, with the same Figures 1 to 4 The method embodiments shown have similar beneficial effects, so details are not repeated here. For the technical details not disclosed in t...

Abstract

The invention discloses a man-machine identification method and device and a computer readable storage medium. The man-machine identification method comprises the following steps of: receiving a logininstruction of an object to be logged in; in response to the login instruction, obtaining operation data of the to-be-logged-in object in a set time period before the moment when the login instruction is received; and identifying the operation data by using a pre-constructed identification model to obtain an identification result. The embodiment of the invention is based on operation data in a set time period before an object to be logged in logs in. Statistical features and nonlinear features corresponding to a series of operations executed before login are extracted by using the recognitionmodel, so that an execution body of the login operation is judged, the man-machine detection recognition rate is effectively improved, and illegal behaviors performed by using scripts without root orinformation tampering and the like can be effectively recognized.

Description

technical field [0001] The present invention relates to the technical field of Internet applications, in particular to a human-computer identification method, device and computer-readable storage medium. Background technique [0002] With the popularization of the Internet and the rise of smart phones, product manufacturers or service providers will use smart terminals to distribute information materials for users or customers to obtain and use. And some criminals will use some scripting methods such as autojs (a JavaScript IDE on the Android platform that supports barrier-free services, which can write various automation scripts), button wizard, and one-touch, etc., to obtain the above-mentioned information through group control operations on a large number of mobile phones. Information material, so that users or customers who really need it cannot obtain this information material, which affects the normal distribution of information material. [0003] At present, the trad...
