  1. The BOSS Project: Recent Advances in Facial Scanning Adam C. Champion

  2. BOSS Project • New York Times reported (Aug. 21, 2013) [1] • Dept. of Homeland Security (DHS) tested Biometric Optical Surveillance System (BOSS) • Goal: identify persons of interest in crowd • E.g., terrorism suspects, criminals at large events • Customers: U.S. police departments • Originally: military (detect persons with IEDs)

  3. Technical Challenges • BOSS faced the following challenges: • Distinguish person of interest in crowd at a distance • Various lighting conditions • Harder to scan a crowd than to scan an individual

  4. BOSS Development • Electronic Warfare Associates. Inc. developed BOSS with U. of Louisville scientist • Two towers with infrared cameras, distance sensors • Compute 3D model of person’s face • Model compared with photos in databases … Criminal?

  5. BOSS Test Results • DHS tested BOSS in a Washington state arena six times • 30 volunteers’ faces compared to 1000 criminals’ faces • Conclusion: police departments should not buy BOSS • Facial recognition accuracy degrades at larger distances • Takes ≥ 30 s to process images

  6. Privacy Implications • The Times story heavily mentions privacy • Currently, there are no “rules” about how a BOSS-like system should be used • Could track people’s movements in public places • Civil libertarians argue for policy establishment • Public has accepted some surveillance in public places like airports

  7. Thank You Questions and Comments?
