The U.S. Department of Homeland Security will test its crowd-scanning facial recognition system, known as the Biometric Optical Surveillance System, or BOSS, at a junior hockey game this weekend, according to the Russian news agency RT.

With assistance from the Pacific Northwest National Laboratory, DHS will test its system at a Western Hockey League game in Washington state. The test will determine whether the system can distinguish the faces of 20 volunteers out of a crowd of nearly 6,000 hockey fans, to evaluate how successfully BOSS can locate a person of interest.
