Smart phone user identity authentication method based on gyroscope behavior characteristics

Abstract

The invention discloses a smart phone user identity authentication method based on gyroscope behavior characteristics. The method comprises the following steps: extracting sensor behavior data corresponding to different operation events according to time information of screen touch operation by analyzing gyroscope behavior data generated during screen touch operation of a smart phone user to generate sensor behavior characteristics; establishing an identity authentication model of the user based on the behavior characteristics; performing identity authentication on the smart phone user. The method disclosed by the invention has the advantages that the method is easy to operate, and any additional equipment does not need to be added; the behavior characteristics of the mobile phone user in an authentication process are described by using gyroscope operation behaviors on the basis of not changing the user habit to lay a basis for user identity judgment, so that smear attack and observation attack can be effectively prevented, and extensive safety and adaptability are achieved.

Description

technical field [0001] The invention relates to smart phone user identity authentication, in particular to a smart phone user identity authentication method utilizing mobile phone sensor data. Background technique [0002] With the rapid development of the mobile Internet, smart phones have penetrated into all walks of life, affecting every detail of people's life and work. Smartphones record and store more and more important data (such as account passwords) and private information (such as text messages and videos) of mobile users. Especially in recent years, the extensive use of mobile payment-related applications and the frequent occurrence of privacy leakage incidents have made people pay more and more attention to the security protection of smart phones. [0003] Safe and effective identity authentication is the core issue of smart phone security protection. It refers to the process that the system confirms whether the user's identity is legal when the user accesses th...
