Tracking users is not only IP recording. You can use a lot of tools to track and analyze users across platforms even without IP. In this session, I will explain how users try to conceal their identities and how to bypass those techniques. How you can detect users and track them even if the use incognito mode. How to track them even if they use VPN or TOR. There are a lot of open source tools and code that is available to help us: from digital fingerprint to forever cookies. From WebRTC local IP detection to DNS cookies. You can use the information in this session to violate's users privacy, or you can use the session information to know how to defend your privacy. I use it for the latter.
