INFORMATION PROCESSING APPARATUS

Learning model generating unit 332 generates a learning model using a user ID of a user estimated by driver estimating unit 331 and driving attributes of the user, as training data. Specifically, learning model generating unit 332 generates a learning model in which the driving attributes are an explanatory variable and the user ID of a user is an objective variable. When various driving attributes are input to this driving behavior model, the user ID of a driver specified by the attributes is output.
