Your personal data is valuable to corporations, governments, and criminals. In part two of User Profiled, VICE investigates a social experiment designed to find out how easily people will give up their personal, private information online. We meet with an online investigator to look at the tools and techniques used to track down people's information online. We interview a high-profile hacktivist to learn about how he's fighting back against increasing surveillance online. And we meet a cybersecurity professional who outlines the steps you can take to keep your messages private and your personal data secure.This video has been made possible by Ubisoft and 'Watch Dogs 2.'
