Embodiment 1

[0023] Such as figure 1 As shown, this embodiment includes the following steps:

[0024] 1) Collect behavioral fingerprints. The behavioral fingerprint includes: the abscissa x of the touch point, the y coordinate of the touch point y, the pressing duration t, the pressing area s, the angular velocity, and the linear acceleration g.

[0025] The angular acceleration includes: X-axis angular acceleration α, Y-axis angular acceleration β and Z-axis angular acceleration γ. When the user performs an input operation through the touch screen, the user's behavioral fingerprint is collected.

[0026] The angular acceleration is collected by a gyroscope sensor installed in the device, and the linear acceleration g is collected by an acceleration sensor. The abscissa x of the touch point, the y coordinate of the touch point y, the pressing duration t and the pressing area s are the data collected directly through the screen.

[0027] 2) Establish a behavioral database for storing be...

Abstract

The invention discloses a mobile terminal user authentication method based on a behavior fingerprint. The method comprises the steps of 1), collecting the behavior fingerprint; 2), establishing a behavior database for storing the behavior fingerprint; 3), establishing an identification model according to the behavior fingerprint in the behavior database; 4), inputting current behavior fingerprint by a user; and 5) carrying out identity identification and carrying out a response by a system if the identity of the user is identified successfully. According to the method, the user identity can be detected and identified accurately, the security cost is reduced, the key storage cost of the user and the risk of losing a key can be reduced, and the authentication is completely carried out based on the behavior fingerprint of the user without an extra support device, so that the authentication can be carried out only by the user behavior information transmitted through the mobile terminal.

Description

technical field [0001] The invention relates to a technology in the field of mobile device security, in particular to a method for authenticating mobile terminal users based on behavioral fingerprints. Background technique [0002] A mobile terminal is a computer device used on the move, including mobile phones and other portable devices. With the development of technology, the mobile terminal has changed from a simple caller to a comprehensive information processing platform. The security of mobile terminals is becoming more and more important, and the passive defense measures usually adopted, such as passwords, lock screen patterns, etc., cannot effectively prevent intruders. Behavioral fingerprints refer to the characteristics of users that are different from others caused by personal habits and biological differences in the operation of electronic equipment. Contents of the invention [0003] The present invention aims at defects such as only gyroscope sensors are us...
