Exploring Privacy Notification and Control Mechanisms for Proximity-Aware Tablets
In hospitals, offices and other settings, professionals face the challenge of accessing and sharing sensitive content in public areas. As tablets become increasingly adopted in work environments, it is important to explore ways to support privacy that are appropriate for tablet use in dynamic, mobile workflows. In this research we consider how spatial information can be utilized to support both individual and collaborative work in a natural way while respecting data privacy. We present a proof-of-concept implementation of a proximity-aware tablet, and a range of privacy notification and control mechanisms designed for such a tablet. Results from a user study support the idea that interpersonal distance and orientation can be used to mediate privacy management for tablet interfaces. Selecting a specific design for privacy threat notification and response is highly context-dependent-for example, in health care the first priority is to not impede the fluid exchange of information.
Abstract Mobile networks have experienced a sharp expansion in the population of mobile clients/subscribers. Such growth incurs additional expending of the bandwidth resources for network cost management. For future PCS (Personal Communication Services) networks, it is desirable to devise mobile networks that make resourceful use of the limited radio bandwidth. Effective mobility and location management is a way to realize such efficiency. This paper surveys different location management strategies and cost planning for personal communication systems. The stress is on how to minimize both the location update and paging costs from the wireless and wired networks.
