Smart phone user identity authentication method based on gyroscope behavior characteristics

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.
