  1. EagleVision: A Pervasive Mobile Device Protection System Faculty Advisor: Dr. Daji Qiao Student: Ka Yang Department of Electrical and Computer Engineering Collaborators: Dr. Wensheng Zhang and Nalin Subramanian (Dept. of Computer Science) SYSTEM DESIGN SYSTEM FEATURES EagleVision provides an integrated protection to both mobile device and the stored data. Specifically, it has the following unique features: • Context Awareness: Sensors carried by the user and the mobile device collect relevant context information (e.g., proximity of the user to the mobile device) and then the system adapts its behavior properly and promptly to the context change. • Transparency: System adapts its behavior autonomously without requiring explicit user intervention or causing distractions to the user. • Low-cost and Light-weight In EagleVision, depending on the proximity of the user to a mobile device, the mobile device may operate in one of the following three safety modes: • Strong Safe Different functional modules are executed at different safety modes and during transitions between safety modes. • Unsafe • Weak Safe SYSTEM MODEL EagleVision consists of the following four components: • Mobile Device Sensor (MDS) • User Sensor (US) • Infrastructure Sensor (IS) • Central Server (CS) At different safety modes and during transitions between safety modes, different functional modules are executed. PERFORMANCEEVALUATION An example deployment of EagleVision in a library Alert dispatch delay to US Registration Delay PROTOTYPE IMPLEMENTATION Lock delay in lobby Lock delay in office MDS is connected with the laptop through USB port US can be carried in the user’s pocket ISs are deployed inside the ceiling CS is implemented on a desktop Unlock delay in office Unlock delay in lobby Theft detection delay via motion detection (in seconds) Alert dispatch delay via text messaging/email (in seconds) PROGRESS ANDFUTUREWORK • “EagleVision: A Pervasive Mobile Device Protection System," submitted to Mobiquitous, Toronto, Canada, July 2009. • Demo: “A Pervasive Mobile Device Protection System,” to appear in the demo session of INFOCOM, Rio de Janeiro, Brazil, April 2009. • Future work: improve the system responsiveness while guaranteeing the reliability of the system. Deployment of the prototype EagleVision ACKNOWLEDGMENT This research is supported in part by • Information Infrastructure Institute (iCube) of Iowa State University • National Science Foundation (NSF) under Grants CNS 0831874 and CNS 0716744 Switching of safety modes in prototype EagleVision (a) An example RSSI trace.
