Title: IDENTITY AUTHENTICATION METHOD, DEVICE AND APPARATUS
Abstract:
Disclosed are an identity authentication method, device and apparatus. The identity authentication method comprises: in the process from a user logging into an account to logging out of the account, calculating first feature data according to a keystroke behaviour of the user when inputting data; calculating a difference between the first feature data and second feature data, wherein the second feature data is used to represent the keystroke behaviour of a legitimate user corresponding to the account; and if the difference is greater than a pre-set threshold value, executing warning processing. In the present invention, a keystroke behaviour of a user is detected all the time in the process from the user logging into an account to logging out of the account, and identity authentication is performed in the whole process, so that the quantity of detected samples is larger. Even if a malicious user obtains login information and bypasses the authentication of a login level, the malicious user can still be identified due to the difference between the keystroke behaviour and the keystroke behaviour of a legitimate user in the process of use, and accordingly, warning processing is carried out, so that account security is prevented from being impaired, and the degree of accuracy is higher.
