The sharing activities of smart devices have been proved to occur commonly among users and discussed by many studies. In contrast to sharing behaviors of personal computer, smartphone sharing is impromptu. It occurs pervasively like on the street between strangers or at home between family members. The variety of sharing behaviors requires the investigation of the most impact factors for smartphone sharing, which underlies the design of usable privacy user interface. This work investigates and analyzes the influencing factors of smartphone users sharing decisions based on CART algorithm of Decision Tree. The data for analyzing is based on a survey involving 165 participants’ responses. Results indicated the features belonging to the sharing attitudes and behaviors impacted users’ sharing decisions mostly.
