Privacy-aware shared UI toolkit for nomadic environments

摘要

As computing becomes more nomadic, privacy becomes a greater concern. People use portable devices to annex displays in their environments so that they can share information with other people. However, private information such as usernames, e-mail addresses, and folder names are shown on foreign displays. In addition, foreign keyboards can be used to enter in passwords generating a significant privacy and security risk. Because nomadic users' sensitive data is constantly at risk for exploitation via the UI toolkit, a solution for protecting user privacy must include that toolkit. This paper introduces the XICE framework— a windowing toolkit that provides easy display annexing and includes a robust privacy framework to help protect users and their data. This paper discusses the exploits that annexing external devices introduces and how XICE mitigates or eliminates those threats safely and naturally for both users and developers.
