  1. Mini Talk Graduate Research Larry Shi Computer Science Department

  2. My Research • When people ask my research Basic research is what I am doing when I don’t know what I am doing.

  3. My research • Secure systems • below OS level • Identity management • for mobile devices • Assistive technologies • using wearable devices

  4. Hardware and physical security

  5. Yes. We go to defcon.

  6. Layered view of security System Firmware Circuit Transistors Physical

  7. Usability and Security Avoid same pw for different sites Interaction speed No "remember me" Instant access No automatically sign in on boot-up Touch based interface Use password with strong entropy Small screen Change password frequently No keyboard Usability often wins this battle in smartphones (It is economy!!!)

  8. Smudge Attack Applied fingerprint powder

  9. Password Doesn’t Solve the Problem 4.7% of users have the password password; 8.5% have the passwords password or 123456; 9.8% have the passwords password, 123456 or 12345678; 14% have a password from the top 10 passwords 40% have a password from the top 100 passwords 79% have a password from the top 500 passwords 91% have a password from the top 1000 passwords http://xato.net/security/passwords

  10. Smartphone Has Many Sensors Sensor Based User Authentication GPS • Cell ID/GPS history. • Touchscreen outputs. • Voices (speaker recognition). • Accelerometer. • Camera. Touchscreen Accelerometer Microphone

  11. Touch Based Authentication Enhance Shape Drawing Access with User Specific Touch Features Touch Gesture Based Authentication Virtual Typing Dynamics Based Authentication Shape Drawing Login Manager Multi-touch Gesture Engine Virtual Keyboard Multi-touch Driver Touchscreen

  12. Touch Gestures from 30 Users

  13. Context-Aware Touch Screen Based User Identity Recognition Under Uncontrolled Environment Data Variation (3 users’ data in Launcher) Result of 8 Users

  14. Computers over Time 1983 1946 1968 2000

  15. What Can Google Glass Do?

  16. Assistive Eyewear Assisted Living Computerized Eyewear

  17. Additional Cases with Difficulties to Recognize Faces • Dementia. • Brain injury. • Memory loss caused by stroke. • Memory disorder.
