Privacy-Preserving Mobile Accesses for Virtual Private Social Media

Online social networking can be accessed by mobile devices, e.g., smartphones which become a platform for social media user interaction. However, although the social media users have the right to turn off and on the application platform, media may be insecurely allowed by followers in many arbitrary situations, and the privacy preserving services are inflexible between followers and followees. This paper proposes a novel technique to generate the flexible and automatic virtual private social media (VPSM) for each follower for every different situation. The VPSM in social media takes into account the location and time information of mobile users. The contribution of this paper includes the location- and time-dependent VPSM which can preserve the privacy of the users and followers while controlling access to media services.
