Embodiment Construction

[0040] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0041] Such as figure 1 As shown, the present invention discloses a method for motion recognition and privacy protection based on acceleration data, the method comprising the following steps:

[0042] S1. Preprocessing the original acceleration sensor data;

[0043] S2. Converting the format of the preprocessed data into characteristic data;

[0044] S3. According to the mutual information theory, calculate the mutual information between the feature data and the action and identity under different sampling rates, and obtain the total mutual information value of the action and the total mutual inf...

Abstract

The invention discloses a method and system for motion recognition and privacy protection based on acceleration data. The method of the present invention includes the following steps: preprocessing the original acceleration sensor data; converting the format of the preprocessed data into feature data; calculating the mutual information of the feature data and actions and identities respectively under different sampling rates according to the mutual information theory , and correspondingly obtain the total mutual information value of the action and the total mutual information value of the identity; visually convert the mutual information value into a solution for the user to choose. The system of the present invention corresponds to the method described above. In view of the development of the existing technology for obtaining personal identity privacy from gait features and the lack of privacy protection schemes for acceleration data, the present invention can be well applied to the protection of personal data privacy.

Description

technical field [0001] The invention belongs to the technical field of information security, and in particular relates to a method and system for motion recognition and privacy protection based on acceleration data. Background technique [0002] At present, most mobile phones and wearable devices have built-in acceleration sensors, and the acceleration data is widely used to identify the user's action state. However, the user's gait behavior has this unique characteristic, which leads to acceleration data being used to illegally obtain identity information. With the popularization of mobile terminals, there is an urgent need for a simple and highly visible privacy protection system to cope with the current trend. Contents of the invention [0003] The purpose of the present invention is to provide a method and system for motion recognition and privacy protection based on acceleration data, aiming to solve the above-mentioned deficiencies in the prior art in the background...
