Document Type and Number:
WIPO Patent Application WO/2019/192253
Kind Code:
A1
Abstract:
Provided in the present invention is a mobile device-based user identity authentication method and system, the user identity authentication method comprising following steps: step S1. acquiring, by means of a mobile device, a sensor signal in respect of the movement of the mobile device from a pick-up position to a stationary state; step S2. filtering the sensor signal; step S3. performing signal preprocessing on the filtered sensor signal, and extracting a time domain feature and a frequency domain feature in a pick-up event of the mobile device; and step S4. inputting the time domain feature and the frequency domain feature in a neural network identification algorithm for training, so as to identify and determine user data. In the present invention, an existing mobile device is used to extract the behavior features of a user, and a neural network identification algorithm of a machine learning identification model is used to identify a user identity, effectively simplifying the process of user identity authentication, and greatly improving the user experience, without adding any hardware cost; moreover, the system is simple and effective, is convenient to use, and has good practicability.
