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)

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

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

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

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
