  2. Project Concept/Motivation • Concept: • This project will act as deterrence against laptop thefts, providing the owner a greater degree of security. • The prototype integrates off-the-shelf embedded components, such as motion-sensing accelerometer, buzzer, RFID reader and tags for passive activation of the device and the Tmote Sensor. • Motivation: • A laptop owner today is unable to leave his/her laptop unattended without risk of the laptop being stolen. • Using our prototype system, an alarm will be activated if the laptop is being handled by unauthorized personnel.

  3. Competitive Analysis: • Caveo Anti-Theft PC Card: • http://caveo.com/products/anti-theft.htm • The product works by sensing motion and emitting an alarm when its moved. • Our product will automatically activate the lock when it does not sense the user’s presence • Kensingston Cable Lock: • http://us.kensington.com/html/11179.html • The product works by physically locking the laptop to a secure object. • Our product requires less user input and is a smaller and lighter solution.

  4. Requirements: • Functional Requirements: • Detects the presence of the user when in range and disarms the device. • Arms the device when user is out of range. • Allows software arming and disarming of device. • Detects movement of laptop when armed and sounds alarm accordingly. • Non-functional Requirements: • Reliability: When armed, the device will detect significant movement and sound the alarm. • Usability: The device will require minimal user input after installation. • Threshold: Non-extended small movements will be tolerated by the system. • Timing: The alarm will trigger within 5 seconds of detection of motion.
