A continuous identity authentication method for collecting user interaction behaviors by using a mobile terminal

The invention discloses a continuous identity authentication method based on a mobile terminal interaction behavior. The method comprises the following steps: (1) collecting user interaction behaviordata; (2) fuzzifying user interaction behavior data; (3) constructing WiFi-geographic position mapping table; (4) generating an interaction event set; (5) constructing a user identity authentication model; (6) obtaining an interaction event departure value; (7) judging the type of the interaction event; And (8) judging the user identity. According to the method, the problem that the user behaviorcollected in the prior art is easily simulated and the problems that the energy consumption is high, the data is not easy to collect and the privacy protection intensity is low when the user behaviordata is collected in the prior art are solved, so that the method has the advantages of safety, practicability and privacy. 本发明公开了一种基于移动终端交互行为的持续身份认证方法，其步骤为：(1)采集用户交互行为数据；(2)模糊化用户交互行为数据；(3)构建WiFi-地理位置映射表；(4)生成交互事件集；(5)构建用户身份认证模
