The TraffickCam app enables travelers to submit pictures of hotel rooms around the world. The images are matched against a national database used by police.
“You just enter your hotel room, and your room number. You take four pictures, and you submit them to the website,” Washington University Researcher and TraffickCam developer Abby Stylianou said. “And then those become part of the pipeline that law enforcement can use to track down where the victims are being trafficked.”
As a frequent hotel visitor, this is something I plan to take a look at. I have no idea how well it works, or how effective it is, but if something as simple as taking a few photos and uploading them can even potentially help, it may be worth it.
