Travelers can now help combat human trafficking using a new app called TraffickCam. Developed by Exchange Initiative and Washington University, the app enables users to anonymously upload photos of hotel rooms along with basic hotel details to assist investigators in identifying locations shown in images posted by traffickers.
In testing, TraffickCam has demonstrated about 85 percent accuracy at matching traveler-submitted photos with hotels in its database. The system relies on subtle visual cues—carpet patterns, furniture placement, bedding, curtains, and window views—to make positive identifications. These visual matches can provide valuable leads for law enforcement working to locate victims and suspects.
“Law enforcement is always looking for new and innovative ways to recover victims, locate suspects and investigate criminal activity. The app created by Exchange Initiative will give law enforcement yet another technological tool to reach that goal in a quicker, more proficient manner when investigating cases involving human trafficking and child exploitation,” said Sergeant Adam Kavanagh, supervisor of the St. Louis County Multi-Jurisdictional Human Trafficking Task Force.
TraffickCam’s database already contains roughly 1.5 million photos and covers more than 145,000 hotels across the United States. The submission process is completely anonymous: the system only retains GPS coordinates provided with uploads and does not store identifying information about contributors. This design helps protect volunteers while still supplying investigators with actionable location data.
The app originated from work by staff at Nix Conference & Meeting Management, the parent company of Exchange Initiative, during the development phase and has recently become available to the public. Exchange Initiative principal Molly Hackett recalls a turning point that motivated the project: “The first time we were able to help law enforcement identify a hotel where a trafficked child had been photographed, we realized that our travel experience was valuable in the fight against trafficking. Our pivotal moment for developing the app came when we couldn’t identify a motel room. We connected the vice squad with our associates in that city, but it took three days to find the girl. That seemed way too long, given today’s technology.”
Dr. Robert Pless, professor of computer science and engineering at Washington University School of Engineering & Applied Science, explained the technological rationale: “Criminals take advantage of technology to advertise and coordinate illegal sex trafficking. We’re using new technologies to fight trafficking, with this app that allows everyone to contribute data and with new image analysis tools to help law enforcement use the images in investigations.”
By crowdsourcing hotel room images from travelers worldwide, TraffickCam expands the resources available to investigators and shortens the time needed to locate victims and disrupt traffickers. The app’s blend of widespread public participation, image-analysis technology, and careful privacy protections aims to make it easier for law enforcement to act quickly and effectively when trafficking images arise during investigations.
