A continuous identity authentication method for mobile devices to collect user motion behavior

Abstract

The invention discloses a continuous identity authentication method for mobile equipment to collect user motion behaviors, the steps of which are: (1) collecting user motion behavior data; (2) synchronizing user motion behavior data; (3) generating time-domain data block sets; (4) Generate a frequency domain data block set; (5) Build a user identity authentication model; (6) Obtain the time domain behavior detection value; (7) Obtain the frequency domain behavior detection value; (8) Determine the type of behavior; (9) Determine user identity. The present invention overcomes the problem that the user behavior collected by the prior art is easy to be imitated and the prior art collects the user behavior data with high energy consumption, difficult data collection, low privacy protection and long single authentication period, making the present invention secure The advantages of security, practicality, privacy and convenience.

Description

technical field [0001] The invention belongs to the field of information technology, and further relates to a continuous identity authentication method for mobile equipment to collect user motion behavior in the field of information security technology. The invention realizes the continuous authentication of the user's identity through the user's motion behaviors such as running and jumping collected by the mobile device. Background technique [0002] The continuous identity authentication method is based on the user's unique behavioral characteristics and cognitive characteristics. By continuously collecting and evaluating user authentication information, it aims to authenticate the user's identity without interfering with the user's normal behavior. Mobile devices contain a variety of sensors that can continuously collect user behavior and cognitive feature data, and build a continuous identity model for users based on the uniqueness of user behavior and cognitive features...

Problems solved by technology

The disadvantage of this method is that the user is easily peeped and imitated when swiping the screen. Once the user swipes the screen and is successfully imitated, the identity authentication mechanism will fail.

But, the weak point of this method is: this method needs to often open GPS sensor in the process of collecting GPS location information data, and power consumption is bigger; When collecting browser browsing record, must obtain the Root permission of mobile device; The method needs to transmit highly private data such as user application usage records, browser browsing records, and GPS geographic location information to a remote server for calculation

Once the remote server is compromised, it will cause serious user privacy leakage; this method can only authenticate the user's identity every 30 minutes, and the single authentication period is too long
