Embodiment Construction

[0034] First of all, according to the change characteristics of people's walking acceleration, a division method based on HMM (hidden Markov) is proposed, and the people's walking acceleration is divided into two parts: relative dynamic and steady state, and the standard deviation, mean value, energy, etc. are extracted from the two regions respectively. feature. Then, these features are selected according to different walking speeds and combined into a new feature set. Finally, the recognition accuracy is obtained by the method with different classifiers.

[0035] specific plan:

[0036] The user carries a mobile phone for walking. The smartphone was fixed on the right thigh of the experimenter, and the specific position was as follows: figure 2 As shown, in the process of data collection, users need to walk for a period of time according to their walking habits in order to obtain stable data. The software platform for collecting data is Sensor Log. Users need to record 3...

Abstract

The invention discloses a walk acceleration information segmentation-based personnel identification method. Walk acceleration data of personnel is collected by utilizing an acceleration sensor arranged in a mobile phone; for further mining acceleration information, an eigenvector is detailed, and an acceleration change rate is explored; an HMM-based information segmentation method is proposed; andthe acceleration data is divided into a dynamic part and a steady part according to a relationship between continuous acceleration data sampling points. Features are extracted from the two parts to form dynamic and static feature sets, and the features are selected from the two sets by applying a Relief algorithm to form a new feature set, so that the personnel identification rate is increased. The personnel identification is performed by utilizing a mobile phone, so that the identification timeliness is improved and the cost is low.

Description

technical field [0001] The invention belongs to the field of information security, and in particular relates to a person identification method based on walking acceleration information segmentation. Background technique [0002] With the advancement of society and the development of mobile computing technology, many electronic devices such as mobile phones, tablet computers and other portable electronic devices are becoming more and more popular, and have become important tools in people's daily work and life. These electronic products often store a large amount of personal sensitive information of users, such as online bank accounts, various account numbers, and electronic certificates. The importance of information security in portable electronic products is becoming more and more obvious, and identity authentication, as a necessary premise to ensure information and security, has become an important guarantee to protect personal privacy and property inviolability.
