A user identification method, device, equipment and storage medium

Abstract

The present invention discloses a user identity identification method, device, device and storage medium, comprising: obtaining the first behavior characteristic data of a first user inputting a password and keystroke; constructing the first behavior biometric fingerprint sequence of the first user, the The first behavioral biometric fingerprint sequence includes a first behavioral characteristic data set of each keystroke when the first user enters the password this time, and the first behavioral characteristic data set includes a plurality of first behavioral characteristic data of this keystroke; according to Multiple sets of the first behavioral biometric fingerprint sequence and multiple sets of public behavioral biological fingerprint sequences obtain the identification threshold of the first user; obtain the keystroke behavior characteristic data of the second user when entering the password, and construct the second user's second behavioral biometric fingerprint sequence; determine the average distance between the second behavioral biometric fingerprint sequence and multiple groups of the first behavioral biometric fingerprint sequence; when the average distance satisfies the identification threshold, it is determined that the second user is the first user.

Description

technical field [0001] The present invention relates to the field of data analysis, in particular to a user identification method, device, equipment and storage medium. Background technique [0002] The existing user identity authentication methods for smart mobile terminals are mainly divided into three categories: [0003] Type 1 Knows: Passwords, Privacy Questions, etc. [0004] The second type of holdings: U-Shield, dynamic tokens, etc. [0005] The third category: fingerprints, faces, voiceprints, etc. [0006] As we all know, the first type of authentication means is easy to be stolen and embezzled in the Internet age. The second type of authentication means requires devices other than smart mobile terminals, which are inconvenient to carry and easy to lose. The third type of authentication method largely solves the problems of being easy to steal and inconvenient to carry, and is currently the most widely used method. However, with the development of science and ...

Problems solved by technology

[0006] As we all know, the first type of authentication method is easy to be stolen and embezzled in the Internet age

The second type of authentication means requires devices other than smart mobile terminals, which are inconvenient to carry and easy to lose

However, with the development of science and technology, human biometric codes such as fingerprints, faces, and voiceprints are copied, disseminated, and abused, and such identity authentication methods are no longer applicable.
