* Robert Pless, Patrick and Donna Martin Professor of Computer Science, was recently awarded a two-year, $1 million grant from the Department of Justice to continue and expand a project that helps law enforcement identify specific hotel rooms where they suspect illegal activity has taken place.

The database compares these with photos submitted by hotel patrons through the smartphone app TraffickCam and photos from a travel website for a match, which can tell investigators key information about where the photo was taken, including the specific hotel or hotel chain. * https://gwtoday.gwu.edu/using-computer-science-tackle-human-...
