Problems solved by technology

[0006] Because of the discreteness and uncertainty of gesture data, both algorithms will inevitably cause partial loss of information
In addition, gesture recognition in the prior art does not consider the impact of environmental factors

Abstract

The invention discloses an identity authentication method and system based on gesture features. The method includes: collecting acceleration data of user gestures; resampling the acceleration data to obtain the processed acceleration data; performing environmental denoising on the processed acceleration data to obtain the denoised acceleration Data; use a support vector machine to identify the correctness of the denoised acceleration data, and if the identification result is correct, the identity authentication is successful. The identity authentication method and system based on gesture features provided by the present invention, on the one hand, can better guarantee the integrity of the collected data; on the other hand, considering the influence of environmental factors, the identity authentication method and system provided by the present invention Under different environmental scenarios, it can still maintain a good recognition rate.

Description

technical field [0001] The invention relates to the field of identity recognition, in particular to an identity authentication method and system based on gesture features. Background technique [0002] With the continuous development of smart phones and Internet technology, mobile phones have gradually become an indispensable part of people's lives. Now people usually use mobile phones as an information processing platform, from chatting and communication, to bank payment, to learning Office and mobile phones have penetrated into every aspect of our lives. With the improvement of the convenience of mobile phones, all kinds of private information will inevitably be stored in mobile phones. If the mobile phone is lost, the result will undoubtedly be catastrophic harm. As the first barrier to protect these private information, mobile phone identity authentication is particularly important. [0003] At present, there are two commonly used identity authentication methods for mo...
