With technology no longer restricted to the home or office, users are now capable of accessing information in virtually any sort of public setting. This creates situations where sensitive information, both organizational and personal in nature, can be seen and captured by nearby people and technology. Even in places like offices and public computer clusters, there is a chance that people will oversee something that is not meant for their eyes. Therefore, methods are necessary to help ensure the privacy and security of displayed information, on mobile devices and desktop machines. This talk gives first gives an overview of o ur recent exploration and testing of different software-based concepts for maintaining privacy (and security) of displayed information. We then summarize the needs for information privacy on various devices, both large and small, and discuss possible future research directions in each of these different areas. Finally, other potential information management and user interaction uses for some of the techniques we have been investigating are presented.
