There is, and my friend can speak to this perhaps.
I know the Toronto Police Service has been very active in trying to track back through image analysis. You may remember the case of images they released, taking out the young girl's image but showing a hotel room or amusement park where she was being abused, and it actually led back to Disney and a hotel there. It turns out she'd had a rescue, but there is a lot of work being done by law enforcement, and some groundbreaking stuff here in Canada I think to track back.
One of the goals—and one of my friends spoke to it—is protecting the public, identifying these kids and rescuing them. It is not just about putting the bad guys away; it is about finding these kids who are being abused. So there is a lot of excellent work being done in that area.
