Picture This: Tracking Thieves & Pedophiles with Image Metadata

Published on

Over the past few years I have developed and used technologies that help recover stolen devices ranging from laptops, cell phones, iPods, flash drives and even high end digital cameras. One tool was CameraTrace which is a massive database of camera serial numbers discovered via distributed bots that scan popular photo sharing and social media websites extracting serial numbers and other data from the metadata of images. The tool has led to the recovery of several stolen cameras and is being utilized by law enforcement agencies across the country including the Homeland Security Investigations Cyber Crimes Center (HSI C3) Child Exploitation Investigations Unit who is using it along with several other sophisticated tools to help track down child pornographers and pedophiles many times before they are able to hurt a child.
