Abstract : During data sharing process across people, users do not want the information that contains privacy to be shared with everyone else; some people may only want to share it with someone they are familiar with. To solve this issue of privacy preservation in data-sharing applications, we propose a novel user-centric method. Our main contributions include the followings. 1 Users can select key words or characters for their own privacy information, which is a user-centric way to protect privacy. 2 During the process of data sharing, data substitution can be used to ensure privacy preservation as well as high successful rate of data sharing. 3 Our method can be used in different data-sharing applications in a flexible way. Simulation results show that our method can achieve our privacy preservation goal.
