Problems solved by technology

Each person's motion characteristics are usually unique, but there is still a lack of technical solutions based on the acceleration sensor in the terminal to detect the motion characteristics generated by the user's static gestures for identity authentication

Embodiment 2

[0146] Such as image 3 The illustrated embodiment of the present invention provides a device for user identity authentication, which includes:

[0147] The acquisition module 301 is configured to acquire the acceleration data detected by the acceleration sensor, the acceleration data is the acceleration data detected by the acceleration sensor and generated by the terminal vibration driven by the muscle vibration of the user to be authenticated while maintaining a static posture;

[0148] The extraction module 302 should perform feature extraction on the acceleration data obtained based on high-order statistics to obtain a set of feature vectors;

[0149] The authentication module 303 is used to authenticate the user to be authenticated according to the feature vector set and the minimum classification hypersphere, which is obtained by training the acceleration data generated by the terminal vibration driven by the muscle vibration of the legitimate user while maintaining a s...

Abstract

The invention discloses a method and a device for user identity authentication. Acceleration data generated by vibration of a terminal driven by muscle vibration of a to-be-authenticated user with static postures is acquired through an acceleration sensor, feature extraction of the acceleration data is carried out on the basis of higher-order statistics, a characteristic vector set is acquired, identity authentication of the to-be-authenticated user is carried out according to the characteristic vector set and the minimum classification hypersphere, physiological vibration of the user with the static postures is detected on the basis of the terminal, identity authentication is carried out, the minimum classification hypersphere is acquired through training the acceleration data generated by vibration of the terminal driven by muscle vibration of a legal user with the static postures, physiological vibration characteristics of different users with the static postures are different, so the minimum classification hyperspheres of each user is different, and identity authentication safety can be realized.

Description

technical field [0001] The invention relates to the technical field of identity authentication, in particular to a method and device for user identity authentication. Background technique [0002] At present, in the network environment, the traditional identity authentication technology determines a person's identity by identifying things such as user names, passwords, ID cards, credit cards, and smart cards that identify the user's identity. However, these methods have security problems such as passwords are easily forgotten, leaked and counterfeited, and items such as smart cards are easily lost and stolen. In order to solve the problem of low security, identity authentication can be realized through image processing and pattern recognition technology based on each person's unique and life-long stable biometric characteristics, thereby improving the security of identity authentication. These biological characteristics include physiological characteristics such as face, ir...
