From 2012 to 2013, students at the University of Colorado’s Colorado Springs campus were secretly photographed as part of a research project. The U.S. Navy wanted to improve its facial recognition algorithms.
To conduct the study, [professor] Boult set up a long-range surveillance camera in an office window about 150 meters away from the West Lawn of the Colorado Springs campus, a public area where passers-by would not have a reasonable expectation of privacy. The camera surreptitiously photographed people walking in the area of the West Lawn on certain days during the spring semesters of 2012 and 2013.
