Embodiment Construction

[0021] Such as figure 1 As shown, this embodiment includes the following steps:

[0022] Step 1. Use the offline classifier module to collect sensor data generated by multiple sets of straight fist movements made by users wearing the device through wearable devices. After denoising the data, extract eigenvalues, and use the eigenvalues ​​as eigenvectors using a class The support vector machine is trained to obtain a classification model and a classifier is established.

[0023] The wearable devices include, but are not limited to: smart watches and smart bracelets.

[0024] Step 2. Use the online identification module to collect the sensor data of the wearer through the wearable device, and classify the classifier established by the offline establishment classifier module according to the eigenvector of the denoised data to determine whether the wearer is the owner, and output the result.

[0025] The biometric information expressed by different people performing the same a...

Abstract

The invention provides a user authentication method used for hand wearable devices and based on straight punch movement detection. The method comprises the steps of adopting an offline building classifier module to build classifiers by collecting sensor data generated when multiple groups of users wearing a wearable apparatus make straight punch movement, via the wearable apparatus, removing noise of the data, extracting feature values, and training the feature values as feature vectors by one-class support vector machines to obtain a classification model; adopting an online identification module to perform classification based on the sensor data of wearers collected via the wearable apparatus, the feature vectors of the data with noise removed and classifiers built by the offline building classifier module, determine whether a wearer is an owner and output a result. Compared with conventional identity identification mechanisms that have been used by most manufacturers, the method has the advantages that the safety is high, eavesdropping is prevented, and fist shaking movement is simple and easy to make, so that the method can be applied to most hand wearable apparatuses.

Description

technical field [0001] The present invention relates to a technology in the field of identification, in particular to a user authentication method for a hand wearable device based on straight fist motion detection. Background technique [0002] In recent years, due to cheapness and convenience, wearable devices have become more and more widely used in daily life. Smart watches, wristbands, etc. provide users with many practical functions, but also bring new security issues. Since a lot of sensitive information is stored on these devices, if there is no corresponding identity authentication mechanism, this information is likely to be eavesdropped by intruders. The identification mechanism of wearable devices needs to apply the existing sensing devices on wearable devices to obtain the user's identity information. Most equipment manufacturers use the following two authentication mechanisms: one is to verify by entering a PIN code. However, due to its characteristics, wearabl...
