Gait bio-feature based mobile device identity recognition method

Abstract

The invention provides a gait bio-feature based mobile device identity recognition method. The method is combined with a mobile terminal and is perfection and expansion of an existing bio-identification technology. The method consists of two parts of a training module and an identification module. The training module comprises three steps of data acquisition, feature extraction and model establishment; and the identification module comprises to-be-identified user data collection, model matching and notification response. According to the method, by utilizing self functions and convenience of the mobile terminal, data is completely acquired, a scientific mathematic basic model is constructed, and gait information of a user is obtained, so that user uniqueness is ensured. A system adopts a national SMS4 symmetric encryption algorithm to perform encryption, so that the data transmission security is well ensured. The method has the advantages that rich sensor and network functions of the mobile device are fully utilized, a modeling process is combined with daily gaits of the user, and the bio-identification technology can be continuously perfected without the need for a deliberate operation. Compared with other identification modes, the security system is relatively high in concealing property and difficult to target. Meanwhile, no contact is required, the concealing is difficult, and remote identification can be performed, so that the user security guarantee is greatly improved.

Description

technical field [0001] The invention belongs to the field of biotechnology identification and mobile terminal security, and aims to develop a mobile device identity authentication method based on gait biometrics, so that the mobile device becomes more intelligent and safe. Background technique [0002] With the improvement of people's living standards, smart mobile devices have gradually become the direction of people's consumption. According to market research reports, the global mobile device market will continue to expand. Smart devices are small and easy to carry. Therefore, many criminals will steal them to obtain illegal income, or use the important information in the device to carry out illegal activities. Not only that, as people's personal belongings, mobile devices have many functions. They not only store contacts' phone numbers, but also a series of sensitive information such as mailboxes and birthdays, and even private information such as photos and text message...

AI Technical Summary

Problems solved by technology

Judging from the existing security software, most of them protect based on passwords or gestures, but this method has its inherent defects, such as easy imitation, easy leakage, no specificity, etc., and the protection is very passive, so Biometrics has become a mainstream security protection method
