A handful of Google engineers has redesigned a set of video and image analysis tools to help find missing children and combat child pornography and abuse. Their effort is now being tested by the National Center for Missing and Exploited Children, and it stems from anti-piracy software Google developed for the company's YouTube division. The software is designed for find patterns in images and video, and the NCMEC will likely use it to track down child predators and find and identify missing and abused children.
