The free app TraffickCam asks travelers to take pictures of their empty hotel rooms and upload them on the site. The goal is to create a database that can be used by authorities to locate human traffickers and their victims.
Hotel rooms are ideal locations for traffickers; they can move on a daily basis making it hard for them to be found. Traffickers also often take photos of their victims in hotel rooms to “advertize” them. With a database of empty hotel room photos, law enforcement will be able to identify the rooms where the pictures were taken by comparing patterns in carpeting or wallpaper, furniture, views from the windows, etc.
