In this talk EFF Technologist Noah Swartz will present Privacy Badger, EFF's new browser extension that automatically blocks both invisible trackers and spying ads. It is intended to be a minimal or zero-configuration option that most Internet users can use to prevent non-consensual third party collection of their reading habits from their everyday browser. Privacy Badger couples the recently developed HTTP Do Not Track opt-out header with a number of heuristics for classifying the behavior of third parties, to automatically determine which should be blocked, which are needed but should have cookies blocked, and which are safe from a privacy perspective. They will also talk about the current state of non-consensual tracking on the web, what methods are currently being used to track people and exploring what alternatives we can pursue.
