Executive Summary

Loaded with personal data, e.g. photos, contacts, and call history, mobile phones are truly personal devices. Yet it is often necessary or desirable to share the phones with others. This is especially true as mobile phones are integrating features conventionally provided by other dedicated devices, from MP3 players to games consoles. Unfortunately, when the authors lend their phones to others, they give away complete access because existing phones assume a single user and provide little protection for private data and applications.
